27 Back to the Future Gadgets and Trends we have in 2025

27 Gadgets featured in Back to the Future' gadgets that are real in 2025 !……

2015 was the year when Back to the Future II promised everything would be cooler.

The first Back to the Future movie hit theaters 37 years ago.

In the sequel, released in 1989, director Robert Zemeckis imagined a futuristic world where people would have hoverboards, food hydrators and automatic dog walkers. Oh, and for some reason, fax machines would still be cool.

Amazingly there are some gadgets the film predicted correctly. Here are a just a few tech tools from the Back to the Future universe that have actually come to life.

1. Phone glasses

Phone Glasses

In Back to the Future II, everyone wore multi-purpose smart glasses to watch TV or answer calls.

Today, we have things like Google Glass and the Oculus Rift for similar-ish tasks, though neither are super mainstream yet.

Marty’s future self gets fired during a video phone call in Back to the Future II. That call is not only prophetic of video chat applications like Skype and Apple’s FaceTime but also of Facebook, in that personal details like date of birth, occupation, political leanings, and hobbies are shared electronically.

BTTF Phone Glasses

Of course, the movie gets a few details a little wrong—like the widespread use of fax machines. But amazing prediction being the movie was released some 36 Years ago

2. Doors with fingerprint recognition (and biometrics in general).

THUMBPRINT BIOMETRICS

Thumb Print Reader

Aside from phones with touch ID, people today can buy door locks that operate with fingerprint recognition.

In BTTF II’s version of 2015, thumbprints are the preferred mode of identification. We first see a futuristic thumb-pad in action when Hill Valley Police use one to identify Jennifer, whom they find sleeping in an alley.

Once at the McFly residence, we see another thumb pad, in the place of a doorknob. They pop up again as a way to make mobile payments. None of that seems very far-fetched today.

The real question when it comes to thumbprints isn’t about the technology itself, but if it’s “the most efficient, reliant way of accelerating and expediting transactions,” says Shawn DuBravac, head of research at the Consumer Electronic Alliance.

What seems more likely is less of a reliance on actual thumbprints and more of one on our smartphones, which DuBravac says “will become an extension of your thumbprint.” That sounds better anyway. If your front door and phone communicate with each other, the door can open while you’re walking toward it, rather than requiring you to press your thumb to a pad.

For an even more futuristic twist, there's a hotel in Barcelona that has a fingerprint recognition system on its doors, as well as a Singaporean hotel that has fingerprint recognition technology. (On top of that, it also largely be run by robots.)

3. Marty McFly's self-lacing Nikes and Smart Clothing

THE SELF-LACING NIKES

Do we really need self-tying laces ?

Not really. Laces are not only very easy to tie, but also quick and don’t exactly require a ton of energy.

But that doesn’t mean that self-tying laces aren’t super cool or make us any less excited about the prospect of someday owning our very own pair of Nike Air Mags.

Gone would be the days of not only your shoes coming untied by accident, but also trying them too tight or too loosely. That’s a world I want to live in.

In the sequel, McFly slips on a pair of self-lacing white Nikes, inspiring a chorus of ooh-ing and aah-ing sneakerheads.

In 2011, Nike actually released 1500 pairs of limited edition Nike Air Mags, replicas of the '80s high-tops.

They were only sold through an eBay auction, with benefits going toward the Michael J. Fox foundation for Parkinson's Research.

 Auto Adjusting/Drying Clothes

Real world technological advancement has led to the public sale of hydrophobic sprays that can prevent items and clothing from becoming wet, but we still don’t have anything close to the amazing jacket that Marty McFly wears in Back To The Future Part II - which not dries itself after the hero’s hoverboard mishap, but even has the capacity to grow and shrink to fit perfectly on a person’s body. This would certainly make shopping a hell of a lot easier (no need to try anything on!), but clothes probably also last a lot longer.

4. TV video calls

VIDEO CALLS IN THE FILM.

TV SKYPE CALLS WITH AN XBOX ONE

Video chatting straight from your TV seemed like a futuristic impossibility in 1989. Today, we have the power of video calling in our pockets. There are also numerous ways to video chat on a TV in today's world, from using a smart TV with Skype to using a BluRay player or an Xbox One.

5. Tablets

Characters casually wield tablets in the film and — surprise, surprise — we're obsessed with the things now. Sure, we all made our jokes when the iPad was initially released, but tablets have since become the perfect in-between for people carrying laptops and too tired to stare at small phone screens.

BTTF Tablet

Mobile Payment Technology

Viewers catch a glimpse of a flat, wireless electronic device in the film, during a scene in which an elderly Terry asks Marty to electronically donate $100—equal to only a couple of inflation-adjusted 1985 dollars—to save the town’s historic clock tower.

Thankfully, inflation hasn’t hit the dollar nearly as hard as Back to the Future predicted. But mobile technology has met and even surpassed that of the devices in the movie—in a way that one of the film’s screenwriters recently said he never could have imagined.

6. 3-D movie obsessions (and never-ending sequels)

Jawes 19 3D

Jaws 19

AN AUDIENCE WATCHES A 3-D FILM

In one scene, McFly walks by a movie theater called a Holomax playing Jaws 19 — and a hologram of a shark leaps out at him.

Sure, we don't have hologram theaters, but 3-D movies have become de rigeur (experiencing a particular boom after the release of Avatar in 2009) and are only becoming more impressive.

Sequels and remakes in general are also getting fairly more aggressive in Hollywood. (Looking at you, Fast and Furious 7 and Spider-Man).

7. Hands-free gaming

THE ARCADE GAME WILD GUNMAN

THE XBOX KINECT Playing video games with your hands is basically like playing "a baby's toy," according to a kid in the film (played by a pint-sized Elijah Wood). Today, we have the Xbox Kinect, which can operate via gestures and spoken commands.

8. Holographic Advertisements

The proliferation of holograms definitely sounds cool, just because the technology would actually be neat to see in real life, but it has its downsides as well. For example, do you really want to be just minding your own business on a street corner and suddenly get attacked by an advertisement for Jaws 19?

9. Dog Walking Drone

Dog Walker Drone

Owning a dog is a lot of fun, but it’s also a lot of responsibility. That fact was surely the inspiration behind the dog walking drone featured in Back To The Future Part II. Sadly, this device would probably be exploited, but it would definitely be helpful if you’re just too busy to go for a walk, or are on vacation and can’t find a dog walker.

Flying drones are ubiquitous in Back to the Future’s 2015, and they’re shown doing everything from walking a dog to capturing images for news organizations.

The latter prediction has come true, and while people still walk their dogs the old-fashioned way, drones—widely available to consumers for about $1,000 a pop—have given us new and creative ways to catch fish, deliver dry cleaning, and make people feel awkward at holiday parties

Owning a dog is a lot of fun, but it’s also a lot of responsibility. That fact was surely the inspiration behind the dog walking drone featured in Back To The Future Part II. It would definitely be helpful if you’re just too busy to go for a walk, or are on vacation and can’t find a dog walker.

10. Floating Back Fixer

BTTF Flying Back Brace

Hurting your back is rough, simply because it means that practically every move you make starts to hurt. It’s why I can have a lot of appreciation for the floating back fixer that George McFly uses in Back To The Future Part II.

11. Food Hydrator

Food Hydrator

A part of me does wonder if the taste of the food featured in Back To The Future Part II is at all affected by the dehydrating/hydrating process, but assuming that it’s not, then hopefully this technology will eventually become a part of our everyday life.

Not only would it make preparing meals incredibly easy, but it would also make it extremely simple to send a great deal of food to people and areas suffering from starvation.

 “Boy, oh boy, Mom, you sure know how to hydrate a pizza.”

But, “Boy, oh boy, Mom, you sure know how to PRINT a pizza” is a total possibility.

“In the future, maybe consumers will go down to the store, pick up a tube of A, B, and C molecules, type ‘filet mignon’ [into their 3-D printers], and they’ll have filet mignon,” says Roger Clemens, a food scientist at USC and spokesman for the Institute of Food Technologists. Early versions of this technology are currently in the works. In fact, a pizza printer exists, though the product doesn’t look delicious, or even edible. Still, the dream of “pizza from a tube of nothing,” as Clemens calls it, is alive.

 12. Sleep-Inducing Alpha-Rhythm Generator

A bad night’s sleep is the worst. You wake up feeling miserable, and that particular feeling seems to follow you throughout the day as everything becomes stupid, annoying, or enraging. If we actually had EZ Sleep’s Sleep-Inducing Alpha-Rhythm Generator, however, all of this would be put in the past. At night, you just point the two lights at your face, and before you know it you’re getting the most restful sleep of your life.

All it takes is a quick flash from Doc’s handheld device made by EZ Sleep, and Jennifer is out cold. A product like this in the wrong hands would be trouble.

“The idea that we can induce a radical change in at least an unhealthy brain with a series of light flashes is not completely out there,” “The demand for it would be incredible. People are definitely looking for that device or that pill that makes sleep automatic.

13. Hoverboards

Can anyone honestly say that they walked away from a screening of Back To The Future Part II without wanting a hoverboard of their very own?

While surely dangerous – just like any skateboard – they look like they’re a ton of fun, and also a good method of transportation.

It’s true that they have their limitations – like lower-power models struggling to work over water – but I wouldn’t even hesitate picking up the real deal if it worked exactly how it does in the film.

We’re talking about a real hoverboard here, not Hendo’s hoverboard, which requires a specialized surface to hover. In BTTF II, the hoverboard Marty borrows from a young girl works on any surface except water.

How far away is that? Frey is firmly noncommittal. “Ten years, 20 years, who knows?” he says. He’s not so quick to discount Hendo’s innovation, though, saying, “It’s an interesting breakthrough in thinking that dramatically brings a BTTF II–type device much closer.”

14. Weather Control and Scheduling

Weather prediction has certainly come a long way since Back To The Future Part II, but sadly we still haven’t gotten to the point where a government body called "The Weather Service" can schedule when it’s going to rain.

It’s a shame it doesn’t exist, because it could not only stop or prevent major disasters, but also save lives. It would even be beneficial for all of us on a day-to-day basis, just because it would allow us all to plan our schedules better around necessary but dreary weather.

15. Mr. Fusion

The Mr. Fusion Home Energy Reactor has a fairly small role to play in Back To The Future Part II, but given that it’s an invention that could potentially solve the world’s energy problems, it deserves very special recognition.

The idea of turning garbage into fuel is one that today’s scientists only dream about, and if the technology were actually invented it could change everything. The version featured in the film isn’t 100% ideal, as it can really only power the DeLorean’s time circuits and flux capacitor and not the car itself, but it is the ultimate step in the right direction.

16. Flying Cars?

Flying Cars back to the Future

When Doc, Marty, and Jennifer first arrive in 2015, the airborne DeLorean is cruising through the sky on a literal highway. According to Thomas Frey, executive director of futurist think tank the DaVinci Institute, we shouldn’t expect to see either of those things, ever.

“We will never get to the flying car era,” Frey told Vulture. “We will get to the era where we get flying drones that haul people, though.” The BTTF II model, in which a person gets behind the wheel of his own flying car, is too dangerous, Frey says.

Flying along the Freeway

Flying Taxi Cab

“Once we get into three-dimensional space, flying vehicles are exponentially more complicated, As for the highway in the sky, Frey envisions a much more sophisticated solution to controlling air traffic. “Directional layers of airspace,” he says, where specific altitudes have a designated direction in which vehicles fly.

Flying DeLorean

Not to Mention the Weight
Don’t believe Goldie Wilson III, grandson of former Hill Valley mayor Goldie Wilson, who charges “only $39,999.95” to convert an “old road car into a skyway flyer.” Frey says, “Traditional cars are way too ‘Heavy’. They’re constructed all wrong for something like that.”

Wilson Hover Conversion

 17. Robot Gas Stations
By 2015, Hill Valley’s local Texaco has lost its attendants, replacing them with a robotic arm that fills the tanks of flying cars. The Dutch have invented a robotic pump, and though these are a long way from ubiquity,

Robot Gas Station

More likely, though, he says, is a variation on the full-service gas station but for electric cars. “Being able to drive over a platform with an electric car, and charge your battery and never have to get out, is entirely possible right now,”

18. Neon Curbs

Neon Curbs

It’s easy to imagine why neon curbs would be common in 2015 Hill Valley, given the need to land a car from above, but don’t expect to see them in real life.

In fact, all public-safety lighting may one day be replaced by jellyfish genes, “We’re able to embed them in trees and plants, and there’s some interesting speculation that a lot of night lighting is going to go away and we’ll have our plants and trees glowing in the evening.”

19. Abolition of the Justice System

Back to the Future Police

 In 2015, Doc tells Marty, lawyers are abolished and the criminal justice moves at the speed of light. That’s how Marty Jr. is tried, convicted, and sentenced within two hours of his arrest.

That kind of justice system would require a society in which “surveillance is so pervasive, intrusive, and thorough that every action (and thought?) could be monitored and recorded.” The technology to achieve that type of surveillance, at least as it relates to actions, exists today, but let’s hope it’s never deployed.

Not because we should fear the technology itself, Smith says, but because of the people behind it. “We would always need to worry about the manipulation of criminal evidence and control of prosecutions by those flawed human beings who are controlling the technology.”

20. Bionic Implants and Rejuvenation Clinics

Technological advancements in BTTF II’s version of 2015 aren’t limited to consumer electronics and transportation. There are a few goodies for those hoping to live forever, too.

Bionic Implants Griff Tannen

Bionic implants are apparently elective enough that teenage Griff Tannen has them, and Doc mentions a trip to a rejuvenation clinic that, among other things, added 30 to 40 years to his life.

Doc Brown Rejuvenation Clinic

Doc Brown Rejuvenation Clinic

Frey, who has written extensively on the future of biotech, says 3-D printing presents an alternative to rejuvenating our failing bodies or augmenting them with mechanical implants.

“There’s all this work being done on 3-D printing body parts. How long until we can 3-D-print an entire replacement body for ourselves?” he asks.

21. Cubs Sweeping the World Series in 5 games

If we would have done this piece a few years ago, BTTF II’s joke about the Cubs finally winning the World Series would be just that — a joke.

But in 2016 just a year after they predicted in the film it actually happened ! ….”If only we could go back in time and put some money on the Cubbies”

Cubs win world Series

22. Computers that take orders via voice controls:

Cafe 80’s

Siri, anyone? And the new Apple TV emphasis on Siri integration makes it even weirder.

23.News footage being filmed by a drone:

News Drone BTTF

Drone footage is increasingly common, though they didn't quite foresee the explosion in the amateur drone market.

 24. Super-thin advanced digital cameras?

Marty McFly and Doc Brown

If anything, Doc Brown is a bit behind the times. Our phones are usually our cameras now too.

25. Large Screen Multi Channel :

BTTF Large Screen TV

While we might not watch six TV channels at once, Marty's son certainly has the same need for multiple streams of information as today's millennials. We just prefer them in rapid succession, on our phones, or via a dual monitor setup.

26. Waste-Fueled Cars

Although you can’t yet buy a vehicle with a fusion engine, like that in Doc Brown’s DeLorean, the scene in which Doc uses garbage to power his car (well, technically the flux capacitor) is prescient.

In fact, Toyota is promoting its new hydrogen fuel cell car—the Mirai—with an ad campaign featuring Back to the Future actors Michael J. Fox and Christopher Lloyd.

Hydrogen-powered cars are lauded as environmentally friendly since they convert hydrogen and oxygen to electricity, with water vapor as a byproduct. That eco-friendliness is partly offset by the fact that fossil fuel or natural gas is typically consumed to create the hydrogen in the first place, but scientists are experimenting with solar and wind-powered generation—and, in Orange County, Calif., hydrogen will be harvested from human waste.

27. Pepsi Perfect

Pepsi Perfect

This one is a marketing stunt, though hardcore fans might not mind: In honor of the trilogy’s 30th anniversary, Pepsi is selling a limited number of bottles of “Pepsi Perfect,” the soda of choice in Back to the Future‘s 2015.

The bottles, sold in the movie for $50

Despite the futuristic packaging, the flavor of Pepsi Perfect is traditional; the company is using natural cane sugar rather than the typical corn syrup. Unfortunately, that doesn’t make it any healthier.

Great Scott !!! How to generate 1.21 Giggawatts (Jiggawatts) with Mr Fusion ...... in the DeLorean Time Machine

We all know what Doc Brown said in the first movie.

"I need a nuclear reaction to generate the 1.21 gigawatts of electricity I need".

GREAT SCOTT !!! HOW TO GENERATE 1.21 GIGGAWATTS (JIGGAWATTS) WITH MR FUSION ...... IN THE DELOREAN TIME MACHINE

Your Built a Time Machine ….. Out of a DeLorean ! ….. We explore the science behind Doc Browns amazing Time Machine, starting with what is 1.21 Gigawatts and how can you generate that kind of Power …….

Great Scott! Marty: What? What the hell is a gigawatt?

1.21 Gigawatts was pronounced (on set) as it were spelled with a "j", as in jigawatts (or jigowatts)..

So, how much is 1.21 gigawatts you ask?

Well, a gigawatt is equal to one billion (10 9) watts or 1 gigawatt = 1000 megawatts.

A watt is a unit of power.

Your typical 100 watt incandescent light bulb draws 100 watts of energy, so 1.21 gigawatts would be able to light over 12 million 100 watt light bulbs. 1.21 gigawatts is also equivalent to 1,621,400 horse power

How does the plutonium in the BTTF car generate 1.21 gigawatts in less than a couple of minuets?

Well the meaning of power (the watt is a unit of power). Power refers to the rate at which energy is produced. Power can be one of several things. The most often way to describe it is the change in energy in a certain amount of time.

1 watt = 1 joule per second where a joule is a unit of energy. Horsepower is another unit of energy where 1 hp = 746 watts.

(roughly equivalent to the amount of energy it takes to lift a medium large apple 3 feet)

If energy is measured in units of Joules, and the time interval is in seconds the power would be in Watts.

What about the giga? Giga is a prefix for units that typically means 10 to the power of 9.

This means that 1.21 gigawatts would be 1.21 x 10 to the power of 9

This means producing a given amount of power in a limited amount of time is not an important problem.

If you have a battery that can store only 1 joule of energy : but will discharge in a nanosecond the power output will be a gigawatt, but only for that nanosecond.

A large marine battery can store 8 megajoules and could theoretically produce 1.21 gigawatts for .066 seconds.

Nowhere in the movies is it stated for how long the 1.21 gigawatts needs to be produced, but we can estimate an upper limit based on the properties of lightning.

A typical bolt of lighting contains about a gigajoule of energy and lasts for .2 seconds.

The dynamics of how the lightning was used to power the flux capacitor indicates that it was directly powered by the lightning and no storage battery was involved. We can therefore deduce that the maximum energy needed to create a temporal shift is 1.21 gigajoules/sec X .2sec = 242 megajoules.

We now have two ways to power the flux capacitor:

The Flux Capacitor Credit : Universal Pictures Amblin Entertainment

1) Feed it directly from gigawatt capable generator or

2) Use a lower power generator to charge up a 242 megajoule battery.

A currently available 242 megajoule battery weighs a little over 200 pounds and is the size of a standard blue home recycling bin.

While this type of battery is not rechargeable and cannot deliver all of it’s energy in .2 seconds it gets us in the ballpark of what is needed.

On the other hand there are no gigawatt generators currently available that could fit in a container sized truck , much less a Delorean.

We therefore conclude that in standard mode the flux capacitor is battery powered for the .2 seconds or less it is in use and the plutonium generator does not need produce 1.21 gigawatts.

A micrometer-sized circulators that can be fabricated on a microchip.

We figured out how to integrate magnetic flux quanta — the smallest units of magnetic field — with microfabricated capacitors and other superconducting circuit elements, so that time-reversal symmetry can be broken.

This led to our new circulator proposal. As with conventional circulators, there is a magnetic field present. But because we can use just one magnetic flux quantum, our design can be microscopic.

See the design similarity: (left) the fictional flux capacitor from the movie and (right) a schematic representation of the proposed circulator. Tom Stace/Screenshot from Back to the Future, Author provided

We’ve nicknamed the device the quantum flux capacitor as its circuit diagram has a passing resemblance to Doc Brown’s mythical invention (which are for sale, sort of).

Sadly for history buffs, our design won’t help much in your DeLorean time machine: it doesn’t reverse time. But its magnetic field does break time-reversal symmetry as advertised and we expect these devices will find applications in future quantum technologies.

Even sooner, they may help in high-bandwidth communications environments like mobile phone base stations in very dense populations, or for ultra-high sensitivity radar where every photon of the electromagnetic field counts.

Great Scott Doc Brown -

 If we allow for a 24 hour recharge time for the battery then the generator only needs a continuous output of 2600 watts. No problem for an eccentric genius.

Paul Grimshaw - IT Architect in the Computer Industry (1983-present)

How many AA batteries would it take to generate the 1.21 gigawatts of electricity needed to send Doc Brown’s Delorean back to 1985?

Let’s see, you can squeeze around 5A at 1V out of a decent NiMH AA cell, so that’s 5W.

To get 1.21GW you would therefore require 242,000,000 cells

NiMH AA batteries weigh around 30g per cell, so 242 million of them would total 7,260 tonnes!. With cabling that’s around the weight of a modern Navy Destroyer ship.

AA batteries are 14mm diameter and 50mm long. Allowing a little room for cabling, you can squeeze 100 batteries in 1000 cubic cm (1 litre).

So for 242,000,000 cells you would need 2,420 cubic metres.  That’s about the size of 10 double decker buses.

So probably not the most practical of options.

Instead, ironically, capacitors would be a much better idea for powering a flux capacitor.

The Flux Capacitor

Not just any old capacitors, but some of the capacitors capable of outputting the highest powers as listed here:

SERIES CMX - Self-Healing Energy Storage Capacitors

The 3330CMX2205 looks particularly suitable, each one capable of outputting 100,000A at 3,300V.

So just four of these could generate a colossal 1.32GW - that’s more than enough to send Doc to 1985 AND power his heated car seats at the same time.

Weighing in at 49kg each, four of these capacitors weigh a mere 196kg - let’s round up to 200kg with some mounting brackets. Spacewise, the bank of four capacitors occupy 0.66 x 0.41 x 0.56m, so these would fit comfortably in the trunk, with room for a set of golf clubs to spare.

Did anybody spot the name of the capacitor manufacturer in the link? Yep, it’s General Atomics. So it may not be Plutonium, but it’s still Atomic powered!

Just the job. To be fair, these capacitors can only output this level of power for a fraction of a millisecond, but I’m pretty certain that’s more than enough time to get back to 1985 as long as the car is going fast enough.

Also they would be ideal for recharging by lightning ready for the trip back. As you can see in the picture, they even have a convenient warning on the front not to handle the lightning whilst it’s running through the cable.

On a slightly more serious note, capacitors are commonly used to provide very high power short duration energy bursts. One example is at the US National Ignition Facility, where they have 4,000 capacitors similar to those above, in this case to power their laser.

 The energy stored is again released in a fraction of a millisecond, but this time at a power exceeding 1 TeraWatt. That’s a thousand times that used by Doc, and it exceeds the peak electricity demand of the entire US.

How Do You Get 1.21 GigaWatts For Your Time Machine?

DeLorean Time Machine

Nizmitz Class Aircraft Carrier

Is that a large amount of power?

Yes. Just for comparison, the nuclear power reactors in a Nimitz Class Aircraft Carrier produces 194 megawatts (1.94 x 108 watts).

Or perhaps you would like to compare this to the flying S.H.I.E.L.D. Helicarrier. With my calculations, I get a power requirement of 317 gigawatts.

What Does Doc Brown Even Mean?

How much power does it take to travel through time?

Well, Doc said 1.21 gigawatts.

If I want to calculate the energy required for time travel, I will need the power (given) as well as the time.

How Long Does it Take to Travel in Time?

That's actually looks like a stupid question. Oh well. Let's take a look at the actual real life footage of the time machine (from the historical archives).

Time travel is possible if you get the car up to 88 mph.

Is this car going 88 mph? Is there any way to tell? Oh, yes. Yes, there is. All I need to do is to look at this car (a DeLorean) and use – video analysis. The clip isn't perfect, but I think it will give a good enough estimate. I can scale the video using the wheel base of 2.413 meters.

Here is a plot of the position of the DeLorean in the first time travel (with the dog in the car).

The slope of this line puts the car's speed at 56.7 m/s (127 mph). Yes, that is faster than 88 mph. I'm not sure why the one frame repeated. Also, there could be a problem with my scale since it was rather difficult to see the car. Here is the next time the car gets to a speed near 88 mph (when Marty first goes back in time).

Well that's not good. This give a speed of 29 m/s (65 mph). For this video, the car isn't quite up to 88 mph so this seems ok. I guess I should look at the last time travel speed (when Marty goes BACK TO THE FUTURE). Oh, actually there is not a good shot to analyze there. Oh well, the second shot is close enough to 88 mph, that I will just stick with that.

What about the time interval? For the first test, I looked at the time from just when the car started to shoot sparks until it "exploded".

This gives a time of 4.3 seconds. But wait !

What about the case when a lightning bolt is used to power the car? For that case, the time machine is only getting power for at most 0.46 seconds. So, there are two different time intervals for two different trips through time.

Time Travel Energy

Now that I have the power AND the time, I can calculate the required energy. Let's just do it (for both time interval estimates).

That's not so bad. I have an energy range with the high end just a factor of 10 higher.

Now, how do you get 5 x 108 - 5 x 109 Joules?

 Doc Brown's first choice was to use plutonium. Although he didn't give too much of the details, I guess he was using Plutonium-239. Pu-239 is radioactive, but I don't think that's how it gave energy in this case.

Instead, I guess that there was some type of fission process that broke the nucleus into smaller pieces. Since the pieces have less mass than the original, you also get energy (E = mc2). The Wikipedia page on plutonium as the details, but let's just say that one Plutonium atom produces 200 MeV (mega electron volts) in the fission process (3.2 x 10-11 Joules).

In a typical nuclear reactor (which probably wouldn't use Plutonium-239), this energy is used to increase the temperature of water to make steam. The steam then turns an electric turbine to produce electricity. Clearly, that's not happening here. I'm not sure what's going on - but surely it's not a 100% efficient process. I am going to say it's 50% efficient.

In order to get 5 x 108 Joules, I would need:

Since 1 Plutonium-239 atom has a mass of 3.29 x 10-25 kg, this would require a fuel mass of just 1.2 x 10-5 kg. That seems possible.

What about a lightning bolt? Could you get this much energy from lightning? According to Wikipedia, a single bolt of lightning can have about 5 x 109 Joules. That would be just perfect for the time traveling machine.

But what if lightning & Plutonium for an energy sources are just difficult to get hold of ?

Maybe batteries would be an interesting way to power this machine.

How many AA batteries would you need? From a previous post,

I already know that a high quality AA battery has about 10,000 Joules of energy. In order to get 5 x 108 Joules, I would need 5 x 104 AA batteries. Of course, that assumes that I could completely drain these batteries in just half a second. Damn, those things would get hot.

AA Batterys

Homework

Clearly, there are other questions. Here are some that I can think of.

How much space would a DeLorean need to get up to 88 mph? You can look up the time for it to get from 0-60 mph and assume that it has a constant acceleration.

At the end of Back to the Future, Doc Brown replaces the Plutonium energy source with a Mr. Fusion. Estimate how much energy he could get from a banana peel.

Mr Fusion Fuel Credit : Universal Pictures Amblin Entertainment

·         If you watch all three movies in the Back to the Future series, there are several times that the car gets up to 88 mph. Use video analysis to check the speeds.

·        

How long would it take current from the lightning strike to travel from the clock tower to the car?

·        

Suppose that Marty is 1 second late on his start to get to the lightning wire. How much greater of an acceleration would he need to make it to the wire on time (assuming that over 88 mph works just as well as 88 mph)?

·        

What if there wasn't a known source of lightning? What other ways could Doc get energy to power the DeLorean in 1955 (or whatever the year was)?

·        

Assume that the energy needed to time travel was directly proportional to the mass of the object. Would the S.H.I.E.L.D. Helicarrier have enough power to go back to 1957?

Wheres Mr Fusion ?

To get some answers, I spoke with Egemen Kolemen. He’s a specialist in the control of fusion plasmas at Princeton University, where he is an assistant professor with joint appointments at the Andlinger Center for Energy and the Environment, the department of mechanical and aerospace engineering, and the Princeton Plasma Physics Laboratory. 

Egemen Kolemen, Princeton University (Credit:

Our Q&A is below, and is lightly edited for clarity.

Carmen Drahl:

Thanks for talking futuristic fusion with me, Dr. Kolemen!

In Back to the Future, the central time travel device was originally powered by plutonium, but this was replaced by the Mr. Fusion reactor.

Mr Fusion Home Energy Reactor Credit : Universal Pictures Amblin Entertainment

What’s the difference between how radioactive plutonium might generate electricity and how a fusion reactor would?

Egemen Kolemen: Radioactive plutonium produces energy by splitting up to smaller elements, which is known as the fission reaction.

In a fusion reactor, we combine small nuclei to make energy. Soon enough, we hope to move from fission to fusion technology just as Back to the Future II predicted.

This would help Doc Brown avoid troubles with the terrorists in the original movie— we use water as fusion fuel and you cannot make an atomic bomb with water!

CD: Mr. Fusion was able to generate power from household garbage— a banana peel, Miller beer, and even a beer can! What are the typical starting materials that are used in fusion reactors today?

EK: We use isotopes of the element hydrogen (known as deuterium and tritium) in current fusion reactors. There is enough heavy hydrogen fuel in sea water, H2O, to fuel the world’s energy needs for billions of years.

CD: In theory, could Mr. Fusion have been generating power by fusing together several different atoms or isotopes contained inside the garbage?

Mr Fusion ReFuelling

Or could the reactor only work by fusing deuterium and tritium in the garbage? In other words— could you generate energy from fusing many different nuclei?

EK: Theoretically, fusing elements lighter than iron releases nuclear energy. If a clever physicist could overcome the engineering problems, a machine like Mr. Fusion could physically make energy by fusing banana or beer which mostly consists of carbon, oxygen and hydrogen. (It would even work for a beer can made of aluminum!). This is the process that happens in the core of large stars which is the birthplace of all the heavy elements in the universe.

Time Machine refuelled

However, as the elements get heavier, the fusion process gets harder and requires more energy to initialize and becomes less economical. That is why we use the isotopes of hydrogen, the lightest element in the universe.

Mr Fusion

There is no physics reason why you could not fuse many different nuclei.

Stars fuse many different elements with each other.

However, just as cars are designed to run with only one specific type of fuel (gasoline, diesel, etc.) to make them more efficient and economical, fusion reactors that work on preset fuels would be cheaper and an easier engineering challenge.

CD: Mr. Fusion was the size of a coffee maker.

That’s pretty tiny compared to the typical fusion reactor— 

the experimental reactor being built in France will be over 5000 tons!

What are the challenges to making fusion reactors small?

EK: The fusion process happens when two particles hit each other each other at high velocity inside the reactor.

So, the energy production in a fusion reactor grows roughly in proportion to the volume (or the number of particles inside) of the reactor.

At the same time, the energy loss occurs mostly due to the drifting particles out from the surface of the reactor. As the reactor size gets bigger, volume which grows roughly as the cube of the radius increases much faster than the surface which grows as the square of the radius.

As a fusion reactor gets bigger the ratio of energy production to losses increases making it easier to produce net energy.

We use very strong magnetic forces to be able to confine the deuterium, tritium and electrons inside the reactor. If one can build superconducting coils that can produce much stronger magnetic fields (i.e. a stronger trap) than the ones available today, a smaller machine might be possible. This is an active research topic!

Interior of the National Spherical Torus[+]

CD: We’ve all seen car engines malfunction. Could Mr. Fusion explode in a mushroom cloud destroying everything in a 250 mile radius if something went wrong?

EK: Fusion is a delicate process that needs constant control. Unlike fission reactors, fusion cannot have a runaway chain reaction. If the “engine” malfunctions, the fusion process would stop immediately. So no explosion is possible. That is one of the many advantages of fusion energy.

CD: Mr. Fusion would have to be doing hot fusion, because cold fusion is a myth, right?

EK: There is no scientifically known net energy-producing cold fusion reaction.

CD: So since you do have to heat your starting materials to extremely high temperatures to achieve fusion, how cool can we make the outside of a fusion reactor—cool enough to safely attach to a vehicle?

EK: The wall inside the fusion vessel would be hot just as the inside of the car engine. However, the reactor would have a cooling system, similar to the radiator in a car, making the outside of the reactor at room temperature. The reactor would be as safe as the car engine.

CD: We still haven’t passed the break-even energy point in nuclear fusion— where we get more energy out of fusion than we had to put in. What gives you reason to think we’ll get there?

EK: We have been running experiments on many different fusion reactors all around the world and comparing the experimental data we obtain to computed simulations of the physics process.

We have been upgrading our simulation capabilities using new numerical methods and tools and checking against the experimental data.

At this point, we can reproduce and predict experimental outcomes in existing fusion reactors. We believe that our understanding of the physics and capability to simulate processes are advanced enough to roughly predict how a reactor will behave.

Based on this understanding, we designed the ITER (International Thermonuclear Experimental Reactor) nuclear fusion reactor. ITER is under construction under an international collaboration, and it is expected to come online in a decade.

We predict that we will obtain 10 times more fusion energy output as the power we put in. As with any research, we can only know the exact answer after running the machine but we try to do our best to predict the reactor behavior.

CD: Thank you for your time, Dr. Kolemen!

As a renewable energy source,  cold fusion is potentially unlimited clean energy. But what is fusion energy, how does it work, and is there such a thing as cold fusion?

You may have heard about cold fusion, the idea that atoms can be fused together without using any significant heat or other type of energy and yet producing a great deal of energy.

This philosopher’s stone has been the object of the quest of many a modern-day alchemist, so we shall leave it to them.

Hot fusion, however, is real. It’s what happens inside the sun and other stars. Nuclei of atoms crash into each other at great speed, resulting in fusion and a great deal more energy released. Research and development into fusion energy is trying to create similar reactions here on Earth at over 100 million degrees Celsius.

The opposite of nuclear fission

Fusion energy, in a way, is the opposite of what we conventionally call nuclear energy – although fusion energy also deals with the nucleus of atoms. In current nuclear power plants, the energy comes from splitting the atom.

Fusion, as the name suggests, produces energy not by breaking atoms apart, but by fusing them together.

The real difference comes from the kind of elements involved in these processes. What we know as nuclear energy requires elements with big, heavy atoms like uranium or plutonium that can be split into smaller atoms.

However, uranium, plutonium, and their fission products are radioactive, which means that when they decay they emit ionising radiation, which in certain circumstances might be dangerous to humans.

Fusion energy instead is based on combining two lightweight atoms – usually hydrogen. When two hydrogen atoms fuse, they create helium.

So not only does fusion energy rely on the most abundant element in the universe, its byproduct can be easily used for medical purposes, or to blow up balloons.

Try pushing two magnets together

How do you fuse two atoms?

The challenge comes from the fact that the nucleus of an atom contains positively charged protons and neutral neutrons, as you will surely recall from your physics class.

Therefore, the nucleus of an atom will always carry a positive charge. Trying to combine it with another one with a positive charge is like trying to push two magnets towards each other. They will resist. This is why fusion energy uses the lightest atoms possible. But it is still very hard.

Inside the sun, fusion occurs because the immense gravity draws atoms together, creating extreme density and enormous heat, which makes the atoms collide with each other at great speed.

The force of gravity is much weaker on Earth, because of the relatively small size of this planet, and the temperature – despite global warming – is nowhere close to the heat of the sun. So how can we create similar conditions here for fusion to occur?

Hotter than the sun

The answer is fairly obvious. To make up for our lower gravity, you simply have to create a temperature hotter than the sun.

Six to ten times hotter, up to 150 million degrees Celsius. Here on Earth this tremendous heat will create the conditions to allow the hydrogen atoms to bump into each other, resulting in fusion and generating even more energy.

Sounds easy? There are quite a few details that need to be ironed out.

First issue: where could you create such a temperature, so that the heated substance wouldn’t destroy everything it touches?

Again, the solution is simple: don’t allow it to come into contact with anything. To achieve this, Russian scientists in the middle of the 20th century developed the tokamak, a chamber the shape of a hollow doughnut, surrounded by powerful magnets.

Inside this chamber, the hydrogen gas is heated to an extremely high temperature and transformed into a plasma state.

The plasma state is one of the four fundamental states of matter, in which the gaseous substance becomes ionised – because electrons orbiting the atomic nuclei are stripped away.

The ionised matter is electrically conductive and therefore the magnetic fields can dominate the behaviour of the matter. That is where the magnets come in.

Magnets can keep this electrically conductive substance from approaching the tokamak’s walls, hovering above it. Inside the plasma, the conditions are suitable for the atoms to bump into each other and to fuse, releasing energy.

The world’s largest experimental tokamak nuclear fusion reactor – called ITER – is under construction in France, to prove the feasibility of thermonuclear fusion as a large-scale and carbon-free source of energy.

ITER is an international research and engineering megaproject involving the European Union, China, India, Japan, South Korea, Russia and the US.

If successful, the facility will turn 50 MW of power inserted into the system – to initially heat the plasma – into fusion power output of 500 MW.

A lot of doughnut

The ITER reactor will be huge:

• the ITER tokamak will be as heavy as three Eiffel Towers;

• the structure of the 1 000-tonne electromagnet in the centre of the machine must be strong enough to contain a force equivalent to twice the thrust of the Space Shuttle at take-off (60 meganewtons, or over 6 000 tonnes of force);

• there will be 18 D-shaped electromagnets around the doughnut-shaped tokamak chamber, each of them 17 metres high and 9 metres wide, weighing 310 tonnes, the approximate weight of a fully loaded Boeing 747-300 aeroplane.

• 270 million degrees Fahrenheit to ignite fusion—a full ten times hotter than the sun's core.

But how could we get that enormous energy out of the doughnut and safely channel it into our homes as electricity?

This is done via the main chamber wall and a region called the divertor, positioned at the bottom of the tokamak. The divertor controls the exhaust of heat, waste gas and impurities from the reactor and withstands the highest surface heat loads. The surface of the divertor is covered by tungsten, the metal with the highest melting point (3422°C).

In 2019, with the backing of the European Fund for Strategic Investments, the European Investment Bank signed a €250 million loan to the Italian research agency ENEA to help build the divertor and tokamak test facility. The plant will test various alternatives to exhaust the huge amount of heat flowing into the divertor component of a nuclear fusion reactor.

A glorified steam turbine

Researchers continue to look for alternatives, but as it stands now the whole process of transitioning the heat to electric power then becomes rather old-fashioned. 

The heat received by the plasma-facing wall and the divertor will be used to turn water into steam, which will drive a steam turbine. divertor, positioned at the bottom of the tokamak“The scientific advances towards fusion energy are not likely to occur like the apple falling on Newton’s head,” says Istvan Szabo, a senior engineer in the European Investment Bank’s energy security division. “You need many more resources.”

Szabo concedes it is possible that tomorrow someone will come up with a completely different solution to harness fusion energy, or a different answer to the need for sustainable energy to power us into the future.

“There are other ideas to compress matter and fuse atoms. For example to use lasers or mechanical compression. And maybe someone will one day solve cold fusion,” Szabo says. “But testing these will all require immense resources.

Thermonuclear fusion is furthest along the research and development phase. It offers the most hope.”

Cold fusion remains elusive—but these scientists may revive the quest

The first public results from a Google-funded project reveal renewed interest in the long-sought but controversial nuclear energy source.

BY MICHAEL GRESHKO

PUBLISHED MAY 29, 2019

Sparking a controversy

Nuclear fusion occurs when pairs of light nuclei fuse together to form a nucleus of net lighter mass, releasing huge amounts of energy as described by Einstein's iconic equation E = mc2.

Inside the sun, hydrogen atoms fuse to produce helium and energy. If successfully harnessed on Earth, fusion could provide humankind with abundant, emissions-free energy—a huge boon to efforts to combat climate change. (As a byproduct, fusion on Earth might also help to address a global helium shortage.)

But getting fusion to work on Earth is tricky, since it's hard to get two nuclei close enough to combine; atomic nuclei are positively charged, so they fiercely repel one another, a hurdle known as the Coulomb barrier.

 Crossing this barrier and realizing fusion power is possible at high densities and temperatures, if the nuclei are confined for a sufficiently long time. But to achieve these conditions, scientists seem to need large, expensive machines and huge amounts of initial power.

“What nature does with the enormous force of gravity in the sun's core is what mankind has been trying to do under controlled conditions in the laboratory,” says physicist Amitava Bhattacharjee, the head theorist at the Princeton Plasma Physics Laboratory, one of the leading fusion research groups in the U.S.

“For the last 60 years we’ve been at this, and I think the progress has been enormous,” he adds. “But we still continue to have a challenge to make nuclear fusion power inexpensively available to people.”

But what if cleverly structured materials could somehow lower the energy needed for fusion? That's what chemists Martin Fleischmann and Stanley Pons at the University of Utah thought they had achieved.

On March 23, 1989, University of Utah chemists Martin Fleischmann and Stanley Pons announced their "cold fusion" device to the world—sparking a scientific firestorm. 

But for many, excitement quickly gave way to skepticism. Early outside attempts to replicate the results didn't turn up massive amounts of heat, nor did the setup appear to yield many high-energy neutrons, a signature of conventional nuclear fusion.

“In March 1989, everybody jumped on this topic, even serious fusion physicists (like me),” Hans-Stephan Bosch, the head of the Wendelstein 7-X fusion experiment at the Max Planck Institute for Plasma Physics, writes in an email.

“However, we didn’t find any positive result confirming their claims. Therefore we finished our work, published it, and closed the topic. My impression is that most physicists and chemists did the same, regarding cold fusion as an 'interesting' episode.”

Ever since, cold fusion largely served as a parable on the perils of irreproducibility. But a small group of researchers and enthusiasts has remained convinced that the phenomenon is real and nuclear in nature, though not necessarily the same thing as fusion.

This scientific circle still does experiments and reports its results in its own meetings and journals, though it has shed the “cold fusion” name for low-energy nuclear reactions, or LENR

Small modular reactors (SMRs) are a type of nuclear fission reactor which are smaller than conventional reactors.

This allows them to be manufactured at a plant and brought to a site to be assembled. Modular reactors allow for less on-site construction, increased containment efficiency, and enhanced safety due to passive nuclear safety features.[1] 

SMRs have been proposed as a way to bypass financial and safety barriers that have plagued conventional nuclear reactors.[1][2]

Several designs exist for SMR, ranging from scaled down versions of existing nuclear reactor designs, to entirely new generation IV designs.

Both thermal-neutron reactors and fast-neutron reactors have been proposed, as well as molten salt and gas cooled reactor models.[3]

A main hindrance to the commercial application of SMRs as of 2015 is licensing, since current regulatory regimes are adapted to conventional nuclear power plants and have not been adapted to SMRs in terms of staffing, security etc.[4] Time, cost and risk of the licensing process are critical elements for the construction of SMRs.[5]

Some larger SMRs require more significant on-site construction, such as the 440 MWe 3-loop Rolls-Royce SMR, which targets a 500-day construction time.[9]

SMRs are particularly useful in remote locations where there is usually a deficiency of trained workers and a higher cost of shipping. Containment is more efficient, and proliferation concerns could be lowered.[10] SMRs are also more flexible in that they do not necessarily need to be hooked into a large power grid, and can generally be attached to other modules to provide increased power supplies if necessary.

Companies that are planning new nuclear units are currently indicating that the total costs (including escalation and financing costs) will be in the range of $5,500/kW to $8,100/kW or between $6 billion and $9 billion for each 1,100 MW plant.

The smallest nuclear reactor in operation today isn't from some startup or a cutting-edge nuclear agency: It's tiny, frozen Bilibino Nuclear Plant in Chukotka, Russia, where up to four different 12 MWe modular reactors have run since 1974.16 Dec 2019

Is it legal to own a nuclear reactor?

While they might un-nerve the neighbours, fusion reactors of this kind are perfectly legal in the US

The Flux Capacitor and How does it work ?

The Flux Capacitor How does it Work ?

As featured in ‘Back to the Future’ a device imagined by Doc Brown when he was standing on the edge of his toilet, slipped and hit his head on the sink, when he came to had a revelation of the Flux Capacitor

The Flux Capacitor

The Flux Capacitor is one of the central pieces of equipment in the DeLorean Time Machine which is what makes time travel possible.

In Theory :

This is essentially a storage device for the huge amount of power 1.21 gigawatts (1,210,000,000 watts) of power, once 88mph is reached power is channelled through three glowing rods. This forces microwaves to flow in one direction meeting in the centre.

A newly developed Flux Capacitor (not for time travel though) uses Quantum tubes of magnetic flux moving around a central capacitor by a process known as Quantum Tunnelling, This creates a brace of wormholes accelerating at different velocities relative to each other.

Flux Capacitor - Back to the Future

1.21 Gigawatts of energy would be released from the Flux Capacitor through the Flux Bands (mounted on the outside of the DeLorean). This would allow for the transition through the wormhole to happen at 88mph, the wormhole would have to be created by the Delorean harnessing two black holes, entangle them, and then separate them again. Except this involves ties between quantum mechanics and classical mechanics. (See our ‘Is Time Travel possible’ blog)

The Back to the Future A-Car (the DeLorean used for close up filming) Flux Capacitor consisted of 3 high pressure gas relays connected to Glass Vacuum tubes.

In this particular theory the space-time continuum is shown to be essentially spherical. The Flux bands allowing the traveller to enter the wormhole in one location in space, but emerge from it in a new location which is exactly the same in space, but entirely different in time. So you travel through time, but remain in the same relative place.

Of course this is far more complex than we have described here, but again see our blog ' Is Time Travel Possible' for more detailed explanation.

The short version is that nothing really stays in place, the world is constantly moving through space, so even a slight displacement in time would be extremely difficult to link up exactly with a particular point in space.

Marty McFly with the Flux Capacitor

DeLorean Power ?

The Delorean runs on regular gas (petrol unleaded) to power its 2.8 v6 Peugeot Renault Volvo (PRV) ZMJ-159 engine. But the Time Machine conversion runs on something little more potent ….

Can a DeLorean go 88 mph? Yes it can it can :

In U.S Spec - 130 BHP - 0.60 in 9.6 Seconds - Top Speed 122 mph

In European Spec - 150 BHP - 0.60 in 8.5 Seconds - Top Speed 129 mph

One of the key problems for the flux capacitor is energy. Even theoretically, the amount of power needed to create a wormhole (as yet, still only a concept rather than a reality) is barely conceivable.

In the film, it’s defined as 1.21 gigawatts (pronounced ‘jigawatts’ in the film). That’s an awful lot of watts, the kind you can only get from a plutonium-powered nuclear reactor, or a couple of seriously huge gas turbines or, say, a bolt of lightning !

So try to explain how much power this is the nuclear power reactors in a Nimitz Class Aircraft Carrier produce 194 megawatts (1.94 x 10-8 watts)

But here we are talking about a Bolt of Lighting which is 300 million volts, and 30,000 amps. For comparison a household current is 240 Volts (120volts for USA) and 16 Amps. And a bolt of lighting is 5 x 10⌃9 Joules perfect for Doc Browns Delorean Time Machine

Giga is a prefix for units that typically means 10⌃9 This means 1.21 gigawatts would be 1.12 x 10⌃9 watts

What other mode of transport requires this colossal amount of power ? Try the S.H.I.E.L.D Helicarrier at 317 gigawatts

S.H.I.E.L.D Helicarrier

The Reactor

So how could that work? Let’s get technical for a second. If the reactor uses (for example) Plutonium-239 (dangerously radioactive by the way), then each atom of the stuff could theoretically produce 200MeV (mega electron volts) during the fission process, equivalent to 3.2×10⌃11 joules of energy. With each Plutonium-239 atom having a mass of 3.29×10-25kg, you would only need a fuel mass of 1.2×10-5kg, which could conceivably fit in the boot of a DeLorean.

So long as it didn’t explode, and 1.21 gigawatts is all the power you needed, then you could conceivably power a time-travelling car.

Then all you’d have to worry about are the complexities of relativity, space-time paradoxes and the impossibility of altering the future by changing history to make time travel by DeLorean a reality.

Ghostbusters - P.K.E Meter - How does it work ?

The P.K.E Meter

Ghostbusters - P.K.E Meter - How does it work ?

Ghostbusters ! So what is the PKE Meter and how does it work ?

The Ghosbusters P.K.E. Meter works similarly to a EMF Detector or a Gas Detector, it is designed specifically to locate P.K.E. (Psychokinetic Energy) in an area. As featured in Ghostbusters 1, Ghostbusters 2 and Ghostbusters Afterlife

It is set to register P.K.E. due to this being the substance that makes up most paranormal entities. The P.K.E. Meter tells the operator if an entity is in the area through both indication of its arms with blinking indicator lights, but also through the LED readout screen.

The P.K.E. Meter also informs the operator of the ghost's classification, and how strong it is. The P.K.E. Meter's power source is just a pair of standard AA batteries.

But what is Psychokinetic Energy ?

Psychokinetic energy (PKE, psionic or psychic energy/force) involves activity dealing with conscious mental energy directly affecting physical objects. It is very specific to consciousness, will, emotion, memory, and other qualities equated with the mind. This energy is very common in Kaf, particularly in the ethereal plane.

Psychokinesis

An umbrella term that is used to describe a variety of abilities that directly manipulate this mental force. In the Arcane Realm, the field of study concerned with phenomena produced by this is called parapsychology.

Research has shown that psychokinetic energy has a sympathetic relationship with electromagnetism. This is believed to be the reason how spirits have PK serve as their sustaining life force, how the neural activity of physical brains produce PK, how PK can affect physical objects, or how electronics can detect the presence of PKE.

Spirits and Psychics are in tune with PKE to the level that they have the access to the following abilities:

P.K.E Meter

Telekinesis

The ability to manipulate objects by the power of thought. Telekinetic force works roughly as an analog to electrostatic force, a mental field generated from the psychic can produce waves that polarized objects which can be attracted or repelled by their field.

Telepathy

Transfer of information on thoughts or feelings between individuals via PKE.

Extrasensory Perception

Perception outside the known physical senses, instead relying on PKE.

Precognition

Perception of information on thoughts or feelings between individuals via PKE.

Dowsing

Ability to locate objects, sometimes using a tool called a dowsing rod.

Energy medicine 

Healing by channeling psychokinetic energy.

Levitation

Bodily levitation and flying, typically by pushing off the ground.

Precognition, premonition and precognitive dreams 

Perception of events before they happen.

Psychometry or psychoscopy

Obtaining information about a person or object, usually by touching or concentrating on the object or a related object.

Remote viewing

Gathering of information at a distance.

Retrocognition or post-cognition

Perception of past events that one was physically present or aware of at the time.

Faith healing

Diagnosing or curing diseases using religious devotion or similar strong beliefs.

Aura reading 

Perception of energy fields surrounding people, places and things.

Astral projection or mental projection

An out-of-body experience in which consciousness becomes separate from the physical body.

After the empirical revolution in academia, mental force was reexamined with its own specific field of study, parapsychology. It was found that spirits use PKE in the same way organic beings use the energy from breaking down chemical molecules into electrical energy.

Spirits in fact use ESP as their way to perceive their environment and respond to stimuli of the ethereal plane, and what they draw upon to manifest in the physical plane.

Despite its development for spirits, it is possible for physical beings to harness this power in their minds.

Those who take it upon themselves to tap into this potential and develop these abilities are known as espers or simply psychics.

P.K.E Meter with the Gigameter

P.K.E Meter

One interesting premise of the P.K.E. Meter is that it can be used to track human biorhythms for use in locating missing humans. However these readings are weaker due to this not being the P.K.E. Meter's primary function. The meters can be adjusted to pick up the location of the Proton Pack.

How to Read a P.K.E. Meter: A P.K.E. Meter measures the Psychokinetic energy in the current area. In order to correctly assess the reading, you must view this guide.

200-300 = No Threat, small to no paranormal activity.

301-450 = Trouble, you have a faint trace of a spook.

451-550 = Biblical Proportions, don't let anyone in your house named "Zuul".

Now that you know how to correctly process the information, now you need to know some other tips.

If the meter is reading very close in between 300-305, you may be picking up a trail of a ghoul that was already in your area. In other words, you are seeing his residual traces.

If you are reading anywhere from a 450-455 when a ghost is present, you are looking at a Class V apparition, a ghost not to be taken lightly.

C/N Above entry sourced from GBHQ's Egon's Lab by Dr. Riddle.

Safety Precautions: There is only one warning about the P.K.E. Meter that should be taken very seriously:

Overload: It is not uncommon for a P.K.E. Meter to overload. This ranges from mild electric shock, to a slight burning of skin and even self-destruct. The P.K.E. Meter is by far the most fragile and sensitive piece of equipment, so treat it carefully.

Time Paradox Explained - Back to the Future

Time Paradox

“Doc: “I foresee two possibilities. One, seeing herself thirty years in the future would put Jennifer into shock and she’d simply pass out. Or two, the encounter could create a time paradox. The results of which could cause a chain reaction that would unravel the very fabric of the space-time continuum and destroy the entire universe!... Granted, that’s the worst-case scenario. The destruction however might be limited merely to our own galaxy.”
Marty: “Well that’s a relief!”
— Doc and Marty discussing the implications of 1985 Jennifer running into her 2015 self.
A paradox, in time travel, is “a situation in which the effect of an incident contradicts or eliminates the cause of that same incident”.[1]
”

— https://backtothefuture.fandom.com/wiki/Paradox

Time travel paradox Explained

The Earth rotates around the sun - the sun rotates around the galaxy - the galaxy moves in the universe. All that being said, if the time machine were possible, the DeLorean would be in a different place, and not the same place each time it moves into the past or future.

Solar System

• Here’s one possible answer: The time machine is still affected by the gravitation pull of a body such as that on Earth.

• Expounding upon that: Views from inside the time machine indicate that the DeLorean time machine is traveling through a portal that only opens when the machine reaches 88 miles per hour.

• Since time travel hasn't been witnessed, it's plausible that the unopened time portals are held in place by the Earth's gravity or by a physical force not yet proven. The ideas behind the first paragraph, about Earth's movement in space, have been discussed in the article about spatial displacement.

DeLorean Time Travel

Behind the scenes

• The word "paradox" is often used to describe a mystery or an unanswered question. eg :

• Paradox was also the title of the musical score played during the scene in Part II in which the time-traveling Doc Brown talked with his younger self while handing himself a wrench to attach the electrical cable to the lamppost in 1955; since Doc Brown caused a "pair o' Docs" to occur.

Doc Brown

Though many paradoxes arise in the trilogy, Doc may be overzealous about them because, though the effects obviously happen, the risk of destroying the space-time continuum may not really exist, mearly being a fabrication of Doc's mind to give reason to fix time-lines.

Evidence of such exists, because 1985 Doc was willing to correct 1955 Doc with the wrench size and give him the suggestion that he was conducting a weather experiment as well as telling him there was going to be a storm. He also gave 1955 Doc information on how to repair the DeLorean, via the letter, while he was stuck in 1885, knowing the risks.

There is nothing in Einstein’s theories of relativity to rule out time travel, although the very notion of traveling to the past violates one of the most fundamental premises of physics, that of causality.

With the laws of cause and effect out the window, there naturally arises a number of inconsistencies associated with time travel, and listed here are some of those paradoxes which have given both scientist and time travel movie buffs alike more than a few sleepless nights over the years.

The time travel paradoxes which follow fall into two broad categories:

1) Closed Causal Loops, such as the Predestination Paradox and the Bootstrap Paradox, which involve a self-existing time loop in which cause and effect run in a repeating circle, but is also internally consistent with the timeline’s history.

2) Consistency Paradoxes, such as the Grandfather Paradox and other similar variants such as The Hitler paradox, and Polchinski’s Paradox, which generate a number of timeline inconsistencies related to the possibility of altering the past.

1: Predestination Paradox

Travel through Time

A Predestination Paradox occurs when the actions of a person traveling back in time becomes part of past events, and may ultimately causes the event he is trying to prevent to take place.

This results in a ‘temporal causality loop’ in which (Event 1) in the ‘past’ influences (Event 2) in the ‘future’ (time travel to the past) which then causes (Event 1) to occur.

With this circular loop of events ensuring that history is not altered by the time traveler, and that any attempts to stop something from happening in the past, will simply lead to the cause itself, instead of stopping it.

This paradox suggests that things are always destined to turn out the same way, and that whatever has happened must happen.

Sound complicated? …… O.K this may sound a grim, but just for a moment Imagine that your lover dies in a hit-and-run car accident, and you travel back in time to save her from her fate, only to find that on your way to the accident you are the one who accidentally runs her over.

Your attempt to change the past has therefore resulted in a predestination paradox. One way of dealing with this type of paradox is to assume that the version of events you have experienced are already built into a self-consistent version of reality, and that by trying to alter the past you will only end up fulfilling your role in creating an event in history, not altering it.

– Cinema Treatment

The Time Machine (2002)

In ‘The Time Machine’ Movie' in (2002) for instance, Dr. Alexander Hartdegen witnesses his fiancee being killed by a mugger, leading him to build a time machine to travel back in time to save her from her fate.

His subsequent attempts to save her fail, though, leading him to conclude that “I could come back a thousand times… and see her die a thousand ways.” After then traveling centuries into the future to see if a solution has been found to the temporal problem, Hartdegen is told by the Über-Morlock:

“You built your time machine because of Emma’s death. If she had lived, it would never have existed, so how could you use your machine to go back and save her? You are the inescapable result of your tragedy, just as I am the inescapable result of you.”

The DeLorean Time Machine

Movies: Examples of predestination paradoxes in the movies include :

12 Monkeys (1995), TimeCrimes (2007), The Time Traveler’s Wife (2009), and Predestination (2014).

Books: An example of a predestination paradox in a book is Phoebe Fortune and the Pre-destination Paradox by M.S. Crook.

2: Bootstrap Paradox

Bootstrap Paradox

A Bootstrap Paradox is a type of paradox in which an object, person, or piece of information sent back in time results in an infinite loop where the object has no discernible origin, and exists without ever being created.

It is also known as an Ontological Paradox, as ontology is a branch of philosophy concerned with the nature of being, or existence.

– Information: George Lucas traveling back in time and giving himself the scripts for the Star War movies which he then goes on to direct and gain great fame for would create a bootstrap paradox involving information, as the scripts have no true point of creation or origin.

– Person: A bootstrap paradox involving a person could be, say, a 20 year old male time traveler who goes back 21 years, meets a woman, has an affair, and returns home three months later without knowing the woman was pregnant. Her child grows up to be the 20 year old time traveler, who travels back 21 years through time, meets a woman, and so on.

These ontological paradoxes imply that the future, present and past are not defined, thus giving scientists an obvious problem on how to then pinpoint the “origin” of anything, a word customarily referring to the past, but now rendered meaningless.

Further questions arise as to how the object/data was created, and by whom. Nevertheless, Einstein’s field equations allow for the possibility of closed time loops, with Kip Thorne the first theoretical physicist to recognize traversable wormholes and backwards time travel as being theoretically possible under certain conditions.

Movies: Examples of bootstrap paradoxes in the movies include ‘Somewhere in Time’ (1980), ‘Bill and Ted’s Excellent Adventure’ (1989), ‘The Terminator’ movies, and ‘Time Lapse’ (2014). The Netflix series Dark (2017-19) also features a book called ‘A Journey Through Time’ which presents another classic example of a bootstrap paradox.

Books: Examples of bootstrap paradoxes in books include Michael Moorcock’s ‘Behold The Man’, Tim Powers’ The Anubis Gates, and Heinlein’s “By His Bootstraps”

Cyberdyne Systems Model 101

3: Grandfather Paradox

The Grandfather Paradox concerns ‘self-inconsistent solutions’ to a timeline’s history caused by traveling back in time. For example :

Again we are going to be very grim for a minuet, if you traveled to the past and killed your grandfather, you would never have been born and would not have been able to travel to the past – a paradox.  Let’s say you did decide to kill your grandfather because he created a dynasty that ruined the world. You figure if you knock him off before he meets your grandmother then the whole family line (including you) will vanish and the world will be a better place. According to theoretical physicists, the situation could play out as follows:

The Grandfather Paradox

– Time line protection hypothesis: You pop back in time, walk up to him, and point a revolver at his head. You pull the trigger but the gun fails to fire. Click! Click! Click! The bullets in the chamber have dents in the firing caps. You point the gun elsewhere and pull the trigger. Bang! Point it at your grandfather.. Click! Click! Click! So you try another method to kill him, but that only leads to scars that in later life he attributed to the world’s worst mugger. You can do many things as long as they’re not fatal until you are chased off by a policeman.

– Multiple universes hypothesis: You pop back in time, walk up to him, and point a revolver at his head. You pull the trigger and Boom! The deed is done. You return to the “present” but you never existed here. Everything about you has been erased, including your family, friends, home, possessions, bank account, and history. You’ve entered a timeline where you never existed. Scientists entertain the possibility that you have now created an alternate timeline or entered a parallel universe.

Movies: Example of the Grandfather Paradox in movies include ‘Back to the Future’ (1985), ‘Back to the Future Part II’ (1989), and ‘Back to the Future Part III’ (1990).

Books: Example of the Grandfather Paradox in books include Dr. Quantum in the Grandfather Paradox by Fred Alan Wolf, The Grandfather Paradox by Steven Burgauer, and Future Times Three (1944) by René Barjavel, the very first treatment of a grandfather paradox in a novel.

4: Let’s Kill Hitler Paradox

We will steer off this subject soon but similar to the Grandfather Paradox which paradoxically prevents your own birth, the Killing Hitler paradox erases your own reason for going back in time to kill him. Furthermore, while killing Grandpa might have a limited “butterfly effect”, killing Hitler would have far-reaching consequences for everyone in the world, even if only for the fact you studied him in school.

The paradox itself arises from the idea that if you were successful, then there would be no reason to time travel in the first place. If you killed Hitler then none of his actions would trickle down through history and cause you to want to make the attempt.

Movies/Shows: By far the best treatment for this notion occurred in a ‘Twilight Zone’ episode called ‘Cradle of Darkness’ that sums up the difficulties involved in trying to change history, with another being an episode of Dr Who called ‘Let’s Kill Hitler’.

Books: Examples of the Let’s Kill Hitler Paradox in books include How to Kill Hitler: A Guide For Time Travelers by Andrew Stanek, and the graphic novel I Killed Adolf Hitler by Jason.

5: Polchinski’s Paradox

American theoretical physicist Joseph Polchinski proposed a time paradox scenario in which a billiard ball enters a wormhole, and emerges out the other end in the past just in time to collide with its younger version and stop it going into the wormhole in the first place.

Polchinski’s Paradox

Polchinski’s paradox is taken seriously by physicists, as there is nothing in 'Einstein’s General Relativity to rule out the possibility of time travel, closed time-like curves (CTCs), or tunnels through space-time.

Furthermore, it has the advantage of being based upon the laws of motion, without having to refer to the indeterministic concept of free will, and so presents a better research method for scientists to think about the paradox.

When Joseph Polchinski proposed the paradox, he had Novikov’s Self-Consistency Principle in mind, which basically states that while time travel is possible, time paradoxes are forbidden.

However, a number of solutions have been formulated to avoid the inconsistencies Polchinski suggested, which essentially involves the billiard ball delivering a blow which changes its younger version’s course, but not enough to stop it entering the wormhole.

This solution is related to the ‘timeline-protection hypothesis’ which states that a probability distortion would occur in order to prevent a paradox from happening. This also helps explain why if you tried to time travel and murder your grandfather, something will always happen to make that impossible, thus preserving a consistent version of history.

Books: Paradoxes of Time Travel by Ryan Wasserman is a wide-ranging exploration on the topic of time travel, including Polchinski’s Paradox.

Are Self-fulfilling Prophecies Paradoxes?

A self-fulfilling prophecy is only a causality loop when the prophecy is truly known to happen and events in the future cause effects in the past, otherwise the phenomenon is not so much a paradox as a case of cause and effect. 

Say,  for instance, an authority figure states that something is inevitable, proper, and true, convincing everyone through persuasive style. People, completely convinced through rhetoric, begin to behave as if the prediction were already true, and consequently bring it about through their actions. This might be seen best by an example where someone convincingly states:

“High-speed Magnetic Levitation Trains will dominate as the best form of transportation from the 21st Century onward.”

Jet travel, relying on diminishing fuel supplies, will be reserved for ocean crossing, and local flights will be a thing of the past. People now start planning on building networks of high-speed trains that run on electricity. Infrastructure gears up to supply the needed parts and the prediction becomes true not because it was truly inevitable (though it is a smart idea), but because people behaved as if it were true.

It even works on a smaller scale – the scale of individuals. The basic methodology for all those “self-help” books out in the world is that if you modify your thinking that you are successful (money, career, dating, etc.), then with the strengthening of that belief you start to behave like a successful person. People begin to notice and start to treat you like a successful person; it is a reinforcement/feedback loop and you actually become successful by behaving as if you were.

Are Time Paradoxes Inevitable?

The Butterfly Effect is a reference to Chaos Theory where seemingly trivial changes can have huge cascade reactions over long periods of time. Consequently, the Timeline corruption hypothesis states that time paradoxes are an unavoidable consequence of time travel, and even insignificant changes may be enough to alter history completely.

Lets explain this theory in a little story ….

A paleontologist, with the help of a time travel device, travels back to the Jurassic Period to get photographs of Stegosaurus, Brachiosaurus, Ceratosaurus, and Allosaurus amongst other dinosaurs. He knows he can’t take samples so he just takes magnificent pictures from the fixed platform that is positioned precisely to not change anything about the environment.

His assistant is about to pick a long blade of grass, but he stops him and explains how nothing must change because of their presence. They finish what they are doing and return to the present, but everything is gone. They reappear in a wild world with no humans, and no signs that they ever existed..

They fall to the floor of their platform, the only man-made thing in the whole world, and lament “Why? We didn’t change anything!” And there on the heel of the scientist’s shoe is a crushed butterfly.

Butterfly Effect

The Butterfly Effect is also a movie, starring Ashton Kutcher as Evan Treborn and Amy Smart as Kayleigh Miller, where a troubled man has had blackouts during his youth, later explained by him traveling back into his own past and taking charge of his younger body briefly. The movie explores the issue of changing the timeline and how unintended consequences can propagate.

Solutions

Scientists eager to avoid the paradoxes presented by time travel have come up with a number of ingenious ways in which to present a more consistent version of reality, some of which have been touched upon here,  including:

–The Solution: time travel is impossible because of the very paradox it creates.

–Self-healing hypothesis: successfully altering events in the past will set off another set of events which will cause the present to remain the same.

–The Multiverse or “many-worlds” hypothesis: an alternate parallel universe or timeline is created each time an event is altered in the past.

–Erased timeline hypothesis: a person traveling to the past would exist in the new timeline, but have their own timeline erased.

Thank you to KEVIN BONSOR & ROBERT LAMB for this excellent article.

Here’s some more Paradox theory’s for you to think about ….

As we mentioned before, the concept of traveling into the past becomes a bit murky the second causality rears its head. Cause comes before effect, at least in this universe, which manages to muck up even the best-laid time traveling plans.

• For starters, if you traveled back in time 200 years, you'd emerge in a time before you were born. Think about that for a second. In the flow of time, the effect (you) would exist before the cause (your birth).

• A math professor travels into the future and steals a groundbreaking math theorem. The professor then gives the theorem to a promising student. Then, that promising student grows up to be the very person from whom the professor stole the theorem to begin with.

• Then there's the post-selected model of time travel, which involves distorted probability close to any paradoxical situation [source: Sanders].

• What does this mean? Well, put yourself in the shoes of the time-traveling assassin again. This time travel model would make your grandfather virtually death proof. You can pull the trigger, but the laser will malfunction. Perhaps a bird will poop at just the right moment, but some quantum fluctuation will occur to prevent a paradoxical situation from taking place.

• But then there's another possibility: The future or past you travel into might just be a parallel universe. Think of it as a separate sandbox: You can build or destroy all the castles you want in it, but it doesn't affect your home sandbox in the slightest. So if the past you travel into exists in a separate timeline, killing your grandfather in cold blood is no big whoop. Of course, this might mean that every time jaunt would land you in a new parallel universe and you might never return to your original sandbox.

The DeLorean TIme Machine

Time travel may be theoretically possible, but it is beyond our current technological capabilities. 

Time travel — moving between different points in time — has been a popular topic for science fiction for decades. Franchises ranging from "Doctor Who" to "Star Trek" to "Back to the Future" have seen humans get in a vehicle of some sort and arrive in the past or future, ready to take on new adventures. Each come with their own time travel theories.

The reality, however, is more muddled. Not all scientists believe that time travel is possible. Some even say that an attempt would be fatal to any human who chooses to undertake it.

Understanding time

What is time? While most people think of time as a constant, physicist Albert Einstein showed that time is an illusion; it is relative — it can vary for different observers depending on your speed through space.

Albert Einstein

To Einstein, time is the "fourth dimension." Space is described as a three-dimensional arena, which provides a traveler with coordinates — such as length, width and height —showing location. Time provides another coordinate — direction — although conventionally, it only moves forward. (Conversely, a new theory asserts that time is "real.")

Most physicists think time is a subjective illusion, but what if time is real? 

Einstein's theory of special relativity says that time slows down or speeds up depending on how fast you move relative to something else. Approaching the speed of light, a person inside a spaceship would age much slower than his twin at home. Also, under Einstein's theory of general relativity, gravity can bend time.

As Marty McFly would say ‘ Doc this sounds Heavy ! ‘

Doc Brown

Picture a four-dimensional fabric called space-time. When anything that has mass sits on that piece of fabric, it causes a dimple or a bending of space-time. The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity.

Both the general and special relativity theories have been proven with GPS satellite technology that has very accurate timepieces on board. The effects of gravity, as well as the satellites' increased speed above the Earth relative to observers on the ground, make the unadjusted clocks gain 38 microseconds a day. (Engineers make calibrations to account for the difference.)

In a sense, this effect, called time dilation, means astronauts are time travelers, as they return to Earth very, very slightly younger than their identical twins that remain on the planet.

Through the wormhole

General relativity also provides scenarios that could allow travelers to go back in time, according to NASA. The equations, however, might be difficult to physically achieve.

Wormwhole

One possibility could be to go faster than light, which travels at 186,282 miles per second (299,792 kilometers per second) in a vacuum. Einstein's equations, though, show that an object at the speed of light would have both infinite mass and a length of 0. This appears to be physically impossible, although some scientists have extended his equations and said it might be done.

A linked possibility, NASA stated, would be to create "wormholes" between points in space-time. While Einstein's equations provide for them, they would collapse very quickly and would only be suitable for very small particles. Also, scientists haven't actually observed these wormholes yet. Also, the technology needed to create a wormhole is far beyond anything we have today. 

Can You Time-Travel?

Alternate time travel theories

While Einstein's theories appear to make time travel difficult, some groups have proposed alternate solutions to jump back and forth in time.

Infinite cylinder

Astronomer Frank Tipler proposed a mechanism (sometimes known as a Tipler Cylinder) where one would take matter that is 10 times the sun's mass, then roll it into very long but very dense cylinder.

After spinning this up a few billion revolutions per minute, a spaceship nearby — following a very precise spiral around this cylinder — could get itself on a "closed, time-like curve", according to the Anderson Institute. There are limitations with this method, however, including the fact that the cylinder needs to be infinitely long for this to work.

An artist's impression of a black hole like the one weighed in this work, sitting in the core of a disk galaxy. The black-hole in NGC4526 weighs 450,000,000 times more than our own Sun. (Image credit: NASA/JPL-Caltech)

Black holes

Black Hole

Another possibility would be to move a ship rapidly around a black hole, or to artificially create that condition with a huge, rotating structure.

"Around and around they'd go, experiencing just half the time of everyone far away from the black hole. The ship and its crew would be traveling through time," physicist Stephen Hawking wrote in the Daily Mail in 2010.

"Imagine they circled the black hole for five of their years. Ten years would pass elsewhere. When they got home, everyone on Earth would have aged five years more than they had."

However, he added, the crew would need to travel around the speed of light for this to work. Physicist Amos Iron at the Technion-Israel Institute of Technology in Haifa, Israel pointed out another limitation if one used a machine: it might fall apart before being able to rotate that quickly.

Cosmic strings

Credit to Aderson Institute

Another theory for potential time travelers involves something called cosmic strings — narrow tubes of energy stretched across the entire length of the ever-expanding universe. These thin regions, left over from the early cosmos, are predicted to contain huge amounts of mass and therefore could warp the space-time around them.

Cosmic strings are either infinite or they’re in loops, with no ends, scientists say. The approach of two such strings parallel to each other would bend space-time so vigorously and in such a particular configuration that might make time travel possible, in theory.

Time machines

It is generally understood that traveling forward or back in time would require a device — a time machine — to take you there. Time machine research often involves bending space-time so far that time lines turn back on themselves to form a loop, technically known as a "closed time-like curve."

The Doctor's time machine is the TARDIS, which stands for ‘Time and Relative Dimensions in Space’.

Doctor Who Tardis

To accomplish this, time machines often are thought to need an exotic form of matter with so-called "negative energy density." Such exotic matter has bizarre properties, including moving in the opposite direction of normal matter when pushed. Such matter could theoretically exist, but if it did, it might be present only in quantities too small for the construction of a time machine.

However, time-travel research suggests time machines are possible without exotic matter. The work begins with a doughnut-shaped hole enveloped within a sphere of normal matter. Inside this doughnut-shaped vacuum, space-time could get bent upon itself using focused gravitational fields to form a closed time-like curve.

To go back in time, a traveler would race around inside the doughnut, going further back into the past with each lap. This theory has a number of obstacles, however. The gravitational fields required to make such a closed time-like curve would have to be very strong, and manipulating them would have to be very precise. [Related: Warp Speed, Scotty? Star Trek's FTL Drive May Actually Work]

Back to the Grandfather paradox

If that were to happen, some physicists say, you would be not be born in one parallel universe but still born in another. Others say that the photons that make up light prefer self-consistency in timelines, which would interfere with your evil, suicidal plan.

Some scientists disagree with the options mentioned above and say time travel is impossible no matter what your method. The faster-than-light one in particular drew derision from American Museum of Natural History astrophysicist Charles Lu.

That "simply, mathematically, doesn't work," he said in a past interview with sister site LiveScience.

Also, humans may not be able to withstand time travel at all. Traveling nearly the speed of light would only take a centrifuge, but that would be lethal, said Jeff Tollaksen, a professor of physics at Chapman University, in 2012.

Using gravity would also be deadly. To experience time dilation, one could stand on a neutron star, but the forces a person would experience would rip you apart first.

Time travel in fiction

Two 2015 articles by Space.com described different ways in which time travel works in fiction, and the best time-travel machines ever. Some methods used in fiction include:

Interstellar

One-way travel to the future: The traveler leaves home, but the people he or she left behind might age or be dead by the time the traveler returns. Examples: "Interstellar" (2014), "Ikarie XB-1" (1963)

Time travel by moving through higher dimensions: In "Interstellar" (2014), there are "tesseracts" (which is the four-dimensional analogue of the cube) available in which astronauts can travel because the vessel represents time as a dimension of space. A similar concept is expressed in Madeleine L'Engle's "A Wrinkle In Time" (2018, based on the book series that started in 1963), where time is folded by means of a tesseract. The book, however, uses supernatural beings to make the travel possible.

Travelling the space-time vortex: The famous "Doctor Who" (1963-present) TARDIS ("Time And Relative Dimension In Space") uses an extra-dimensional vortex to go through time, while the travelers inside feel time passing normally.

Instantaneous time jumping: Examples include "The Girl Who Leapt Through Time" (2006), the DeLorean from "Back To The Future" (1985), and the Mr. Peabody's WABAC machine from "The Rocky and Bullwinkle Show" (1959-64).

Time travelling while standing still: Both the "Time Machine" (1895 book) and Hermione Granger's Time-Turner from "Harry Potter" keep the traveler still while they move through time.

The Time Machine

Slow time travel: In "Primer" (2004), a traveler stays in a box while time traveling. For each minute they want to go back in time, they need to stay in the box for a minute. If they want to go back a day in time, they have to stay there for 24 hours.

Traveling faster than light: In "Superman: The Movie" (1979), Superman flies faster than light to go back in time and rescue Lois Lane before she is killed. The concept was also used in the 1980 novel "Timescape" by Gregory Benford, in which the protagonist sends (hypothetical) faster-than-light tachyon particles back to Earth in 1962 to warn of disaster. In several "Star Trek" episodes and movies, the Enterprise travels through time by going faster than light. In the comic book and TV series "The Flash," the super-speedster uses a cosmic treadmill to travel through time.

Star Trek

Difficult methods to categorize: There's a rocket sled in "Timecop" (1994) that pops in and out of view when it's being used, which has led to much speculation about what's going on. There's also the Time Displacement Equipment in "The Terminator" movie series, which shows off how to fight a war in four dimensions (including time).

So is time travel possible?

While time travel does not appear possible — at least, possible in the sense that the humans would survive it — with the physics that we use today, the field is constantly changing. Advances in quantum theories could perhaps provide some understanding of how to overcome time travel paradoxes.

One possibility, although it would not necessarily lead to time travel, is solving the mystery of how certain particles can communicate instantaneously with each other faster than the speed of light.

In the meantime, however, interested time travelers can at least experience it vicariously through movies, television and books.

More Time Travel and Philosophy

In general relativity, things called closed time-like curves can exist, and are a way to solve general field equations.

It’s like stepping on a train, taking a wonderful trip through the mountains, and returning to the same spot you left off, both in space and in time.

That means the moment where you step off the train is both in the past and future of when you got on the train in the first place. In a closed time-like curve, an object returns to the same place and time that it was in the past, completing a loop. It’s unclear if closed time-like curves exist in our universe, but if they do, mathematically, they would allow for time travel.

Then there’s option two.

In this quantum mechanical model, each choice opens up another universe. If time travelers changed something in the past, they would enter another parallel universe.

The original timeline would still exist, one among many branching worlds. In such a model, it might be very hard for time travelers to return to the universe they came from.

Finally - if time travel is possible, time travelers can only do certain things.

A time traveler who went back in time, for example, could not kill Hitler, no matter what he tried. This raises all sorts of philosophical problems - does the time traveler still have free will? It’s difficult to say time travel is possible while simultaneously destroying freedom of choice.

Paradox-Free Time Travel While Preserving Freedom of Choice

That’s where young physicist Germain Tobar steps in.

Under the supervision of physicist Dr. Fabio Costa, Tobar came up with a way to mathematically preserve freedom of choice, while allowing for paradox-free time travel.

For example, let’s imagine there is a scientist in a laboratory with a time-traveling coin.

The coin enters the laboratory at some point in the past as “heads” and leaves at some point in the future as “tails”. Tobar’s model fixes the boundary conditions - the point in time where the coin enters and leaves the laboratory - as always heads and tails.

Then, his model allows the state of the coin to change when it is in the laboratory. Since the initial and final state of the coin is fixed, a paradox is avoided. However, anything can happen to the coin when it is in the laboratory. “For example,” says Tobar, “she [the scientist] can decide to always flip the coin, or always prepare heads regardless of what she got... it can flip, it can hit other coins, and so on.” But no matter what she did or how hard she tried, each time the coin time-travels through her lab, it will always leave as “tails”.

Let’s take another pertinent example. “Say you traveled in time, in an attempt to stop COVID-19’s patient zero from being exposed to the virus,” Costa says. “However if you stopped that individual from becoming infected – that would eliminate the motivation for you to go back and stop the pandemic in the first place.”

In Tobar’s model, no matter what you did, the virus would still escape somehow. “You might try and stop patient zero from becoming infected, but in doing so you would catch the virus and become patient zero, or someone else would,” says Tobar. “No matter what you did, the salient events would just recalibrate around you.”

Even time travellers couldn't stop the spread of the coronavirus.

That means that you have complete freedom of choice, but no matter how hard you tried, you could not stop COVID-19 from escaping.

But this is good news for Marty McFly in Back to the Future. Nothing he did could prevent his parents from falling in love and getting married, and eventually, allowing Marty to be born. Other things might change, like how they met, or what his father ate for breakfast that morning. But nothing could change their eventual meeting.

This doesn’t necessarily rule out other models of time travel, for example, a quantum mechanical one.

Quantum Mechanics

“Some of the quantum approaches would indeed invoke the existence of multiple universes, which interact through the time machine, possibly creating alternate timelines,” says Tobar. Instead, Tobar and Costa’s model is classical and shows that if only one universe exists, it is possible to allow for paradox-free time travel.

This work has other implications as well, including the unification of quantum theory with general relativity. “One of the main issues is that, in such a theory, time seems to disappear, making the traditional, temporal view of dynamics unsuitable,” says Tobar. “Our work presents a different way to look at physical laws, which could find applications in theories of quantum gravity.”

Could closed time-like curves, and potentially time machines, exist in our Universe?

Credit to Anderson Institute

“Proposals so far involve exotic matter (with negative or infinite energy), and we don't know if such matter exists in our universe,” says Tobar. “An interesting consequence is that the CTCs [closed time-like curves] would only exist after a certain point in time, which means it would not be possible to time travel to before the first time machine was created. This would explain why we haven't seen any time traveler from the future yet.”

Great Scott !!! Just look at our latest Time Machine Feedback !!!

Amazing Feedback from Rosie !!! Please read here Google Review on our DeLorean Time Machine Hire !!!

”5 stars is not enough for Mark, the Delorean and the service we received.

I contacted Sandstone productions regarding the Delorean as my husband to be was a massive massive back to the future fan and wanted to surprise him on our wedding morning.

Mark was prompt replying and really helpful, he wasn’t pushy salesman and it was a really easy booking process.

I was unsure if it would be to much for a quick car journey but I was wrong, not only did it make my husband cry with happiness it made every guest talk about it at the wedding.

Mark was so so lovely, he was smiley, happy for people to take pictures and didn’t rush us. He made us feel like our wedding day was the most important day although I’m sure he does a lot of weddings.

He took some fantastic pictures of us and sent them through via email days after.

The Delorean was amazing and the details were incredible.

Mark himself knew a lot about the film, what made my husband comfortable to be excited and really really enjoy the moment without embarrassment. I highly highly recommended Mark, the Delorean and Sandstone Productions and can safely say it was the best thing I spent money on at the wedding”.

21 DeLorean Facts - Click on picture to find out more !

HOW FAST CAN A DELOREAN GO ? 129 MPH - 0.60 in 8.5 seconds (in european spec)

21 DELOREAN FACTS :

1. The DeLorean DMC-12 was the vision of automotive industry executive John DeLorean, who worked for Chrysler, Packard, Pontiac and Chevrolet before setting up his own company in 1975. 

John Z DeLorean Living the Dream

2. The car was built in Dunmurry, a suburb of south-west Belfast, with the first car rolling off the production line on January 21, 1981. 

DeLorean Motor Company Factory

3. Approximately 9,000 were made before production halted in early 1983. Only 16 official right-hand-drive cars were ever produced. 

DeLorean Production

4. The brand new 72-acre factory was claimed to have a capitalization value if $156 million. Would produce 30,000 cars per year a short fall from the 7,500 made whilst the plant was in operation.

New DeLorean Factory

5. The body panels weren’t painted, as they were made from the same brushed stainless steel used in the catering industry, SS304 austenitic stainless steel

Stainless Steel DeLorean Prototype

6. However, 3 cars were plated in solid gold. The original plan was to build 100 as part of a Christmas 1980 promotion for American Express gold card members. Only two of the $85,000 cars were sold, but a third was also built with spare parts, in case one of the other two was damaged. 

Gold Plated DeLorean

7. John DeLorean managed to design, engineer, build a brand new factory, staff it with 3000 staff, and produce a car in a record 28 months. To date this has never been replicated.

Proud DeLorean Factory workers

8. The official 0-60mph time for the DMC-12 in US Spec was 9.0 seconds, from the 130hp

DeLorean Performance

9. The #DMC-12 was so named the because it was originally priced at $12,000. However, by the time it came to market, the car had a suggested retail price of $25,000 (optional extra was an automatic transmission for an extra $650). 

Last DeLoreans sold

10. A total of six DeLorean cars were used for the making of the Back to the Future movies, along with one built entirely out of fibreglass for scenes in which the car had to fly. Only three of the cars still exist, plus the one that was destroyed at the end of the trilogy’s final film.

DeLorean Train Scene - Back to the Future III - This was one of the real cars used in filming

11. The doors have space-age tech developed by the defence industry, Grumman Aerospace developed the doors' torsion bar (which helps with the lifting and lowering) and did most of the manufacturing under cryogenic conditions to ensure longevity. When not working on the DeLorean, Grumman made things like the Apollo Lunar Module and the F-14.

DeLorean Gull Wing Doors

12. The government used DeLoreans to test airbags, DeLorean originally intended the DMC-12 to be an extremely safe vehicle -- in fact one of the top contenders for the car’s name was DSV, "DeLorean Safety Vehicle." The company even donated two of the early prototypes to the NHTSA for airbag crash tests. 

13.  Before starting his eponymous company, John Z. DeLorean was one of GM's brightest stars, He headed up Pontiac in the 1960s, where he was responsible for the birth of legendary cars like the GTO and Firebird, before running Chevrolet in the early 1970s and making a few enemies at GM along the way.

14. The car’s shape was penned by legendary designer Georgette Giugiaro, Even if you’ve never heard of Giugiaro, you know his other works: the BMW M1, Yugo, Lotus Esprit, and Lexus GS all came from his mind, to name just a few.

15. The chassis was engineered by Lotus founder Colin Chapman. Well, it was actually re-engineered by Chapman, because the first design used unproven techniques. The chassis shares much of its components with the Lotus Esprit, and made by GKN England

Colin Chapman and the Lotus Esprit

16. The engine? Straight out PR of a Volvo. DeLorean went through a couple of engine plans, including a rotary engine like you’d find in a  Mazda RX-7, But ultimately, a version of a V6 developed by Peugeot, Renault, and Volvo found its way into the rear. The engine was a version of the 2.8-litre V6 that was developed jointly by Peugeot, Renault and Volvo. The Volvo varient was fitted (as this had already passed the strict U.S EPA emissions in the Volvo 260), and later the Volvo 760 (using the Bosh K-Jet tronic. Surprisingly, plutonium- and garbage-powered nuclear reactors were never taken into consideration.

PRV Engine - DeLorean

17. John DeLorean had plans for a DMC 24 (Which would have been a 4 door saloon), a Twin Turbo DMC-12 with 0-60 around 5.5 Seconds.

DMC -24 1984 After the DeLorean DMC-24 project ran out of money, Giugiaro converted the full-size design proposal for the DMC-24 Sedan into a Concept 'Lamborghini Marco Polo', presented in Dec. 1982 at Bologna Motor Show.

18. The "A" hero DeLorean time machine used throughout the entire film series was painstakingly restored by Temporal FX and is now on permanent indoor display at the Petersen Automotive Museum in Los Angeles, California.

19. The DeLorean time machine which was outfitted for stunt work with train wheels for Back to the Future Part III is now on display at Universal Orlando next to Doc Brown's time traveling train from Back to the Future Part III.

20. The third remaining time machine was retrofitted with 1950's white-wall tires in Back to the Future Part III, and is now in private hands.

Now in a Private collection sold for $550,000

21. The time machine which was hit by the train at the end of Back to the Future Part III was the "B" main stunt car used throughout the trilogy. To create this effect, the special effects crew cut up the car and frame, rigging it with explosives. The wrecked body panels were reassembled after filming, and the DeLorean was suspended from the ceiling for a number of years at the Planet Hollywood Honolulu restaurant in Hawaii (closed in 2010).

Back to the Future - Fashion

The clothing and accessories that people wear are a distinctive part of the popular culture. Clothing styles change not only with the time period, but also communicate one's social class and occupation. Those who don't dress appropriately are often viewed as outcasts or rebels, or at the very least, odd and out-of-place, so Marty McFly's clothing proved to be an endless source of embarrassment for him during his adventures, in spite of Dr. Emmett Brown's attempts to be prepared.

They generally had three options when they traveled from one time period to another:

• They purchased and changed clothes after arriving in a new time period

• They tried to find appropriate clothes for their destination before traveling

• They neglected to change clothes and just endured the awkwardness of attracting attention.

Note: Outfits are described here under the time periods the clothing came from, which were not necessarily when they were worn.

Back to the Future Fashion

Outfit 1: Marty McFLY

This Marty McFly outfit is probably the most iconic of them all.

Everything from the vintage wash denim jacket and faded dad jeans, to the orange puffer vest, looks as good now as it did back in ’85.

Trainers

They’re the overwhelmingly popular Nike Killshot 2 which was originally released in the ’80s and saw a surge in interest when it re-released in 2009, and subsequently in 2014 in collaboration with J.Crew.

Marty

"Life preserver" First day of school in 1955 

• Marty wore a red and gray jacket (that he took off in the school cafeteria), white shirt with light blue rectangles, brown pants, brown loafers (slip- on shoes), and had hair tonic in his hair.

"Darth Vader" 

• The day of the skateboard chase – Marty wore the same red and gray jacket, this time with a black shirt with red chain link pattern, brown pants and Converse Chuck Taylor All-Star shoes.

"That zoot suit" 

• Marty wore a gray wool suit, a white shirt and narrow red tie, that afterwards he called a “zoot suit”. "Get yourself some 50’s clothes ... something inconspicuous!"

—Doc to Marty

Marty in his "inconspicuous" disguise.

• "Something inconspicuous"– Marty chose an “inconspicuous” outfit to cover his basic outfit; he added a black felt fedora hat, black leather jacket and dark sunglasses. When Biff confronted Marty, he referred to the outfit as "that stupid disguise".

• After getting to Biff's car, Marty took off his sunglasses. At the Enchantment Under the Sea dance, Biff's gang member Match wondered how he changed his clothes so fast. After being knocked down by a door as his other self ran through it, and when Biff stole back the almanac, Marty was forced to abandon the fedora, which had fallen off his head. When taking Doc back to his mansion, Marty put the jacket and Nikes by the fireplace, along with the letter, so they could dry off.

At the Delgado Mine – Marty wore the same clothes as the day of the skateboard chase, and added a tan overcoat.

Marty's 1955 western outfit

• "Clint Eastwood never wore anything like this" – Doc prepared Marty to travel to 1885 with a pink and blue shirt with long, yellow fringe running along the chest, back and sleeves, under five embroidered atomic model designs on the front and back of his shoulders, a red bandana around his neck, red corduroy pants, an ornately tooled belt with golden sunburst buckle, white Nike sneakers, and carried along a white cowboy hat and boots that were too tight.

Outfit 2: Biff Tannen

Clothing in 1985

"C'mon, I had to change! You think I’m going back in that-- that zoot suit?"

—Marty

Basic outfit –

Marty McFly

Marty McFly

Marty McFly

• During most of his adventures, except when he changed clothes in 1955 and 1885, Marty wore Guess blue jeans with black 3/4" suspenders, a red t-shirt, lavender ("purple") Calvin Klein underpants, and white Nike Bruin shoes with red swoosh and backtab

(no word Nike on them until he visited 1885) with gray socks (changed to white socks when he visited 2015).

School outfit –

Marty McFly at School

• From Friday before school through his first day in 1955, Marty added a Guess Marciano two-tone blue denim jacket with an "Art in Revolution" button, a Fender P-Bass pin and a white checked Shah Safara shirt to his basic outfit.

• He accessorized this with a Casio CA50W digital watch on his left wrist, a silver Aiwa model HS-P02 Walkman, and mirrored Zeiss aviator sunglasses with a sweatguard in the morning.

• "Life preserver" – From the evening at Twin Pines Mall through his first day in 1955, Marty added a dark orange Class-5 bubble down vest to his school outfit.

• Tales From Space – Doc gave Marty a yellow full-length radiation suit for protection when loading the plutonium. Due to the similarity of his outfit to that of a space alien on a comic book cover, his outfit scared the Peabody family and an elderly couple driving past Lyon Estates in 1955.

• "Darth Vader" – Marty wore the yellow full-body radiation suit, a hair dryer from Doc Brown's suitcase tucked into a belt, and held his Aiwa portable stereo cassette player.

Biff

Although Biff was fabulously wealthy as a result of his cheating with the almanac in 1985A, his sense of dress was still tacky as the Biff of the original timeline. His outfits were gaudy and ugly, with gold chains and bright blue blazers, giving him the appearance of a lounge lizard. After coming out of the hot tub, Biff wore a blue bathing robe over black swim shorts.

Other distinctive clothing of 1985A

§  Biff's bodyguard Match wore a white cowboy hat.

§  Biff's goon 3-D no longer wore his nominal 3-D glasses as the 3-D movies fad had long since faded by 1985. However, unable to part with the nickname, he wore aviator sunglasses which he had custom made, the left lens to be red and the right lens to be blue.

Clothing in 1885

"You can’t wear those futuristic things in 1885. You shouldn’t even be wearing them in 1955."

—Doc Brown at the Pohatchee Drive-in

Marty

"Clint Eastwood never wore anything like this" – (See: 1955 Marty)

Marty's 1955 western outfit plus hat.

"You sure look like Seamus McFly" – Same as "Clint Eastwood never wore anything like this" (see: 1955 Marty), with a straw derby hat[6]

"Some respectable clothes and a fine hat" – Most of the week, Marty wore a long, blue workshirt, brown jeans, and a brown sarape over long underwear, with a brown flat-topped hat, and boots.[7] The outfit was very similar to the one Marty saw Clint Eastwood wearing in A Fistful of Dollars.

"Go ahead, make my day" – One morning, Marty woke up wearing his long underwear with a half-fastened drop seat, and put on his hat and gun belt to practice in front of the mirror.

Behind the scenes

1955

Bob Gale said that costume designer Deborah Scott found nearly all the clothing for the film in the studio’s wardrobe department; they didn’t have the budget for her to make many original items.[8]

Lea Thompson found the pink dress uncomfortable to wear and even more uncomfortable to dance in, and would walk around the set in the 1950s corset bra and crinoline underskirt to avoid wearing the dress, and once even shocked her mother when she visited her on the set. But despite that, she still hung on to one exemplar of the dress that was given to her, and helped out with the filming of the second movie when the original dress had been lost, and she provided it herself.[9]

The black fedora Marty wore as apart of his 'something inconspicuous' disguise was made by the Stetson hat company, especially for Michael J. Fox.[10]

2015

Costume designer Joanna Johnston said she was terrified at the prospect of designing the clothing of the future, making costumes for the cast and 150 extras from scratch, since Bob’s concept did not have a basis in anyone else’s work. For a future society in which men and women are truly equal, the clothing styles would exaggerate the difference between the sexes. She decided to use a very wide variety of fabrics in bright "but not fluorescent" colors.[11]

1885

Costume designer Joanna Johnston was already familiar with the clothing for the period, having worked on the movie Tess, but found that most of costumes that were made for the Westerns of the '40s, '50s and '60s lacked the authenticity she was looking for. After further research, she created clothing for the main characters and as many as 500 extras based on the original clothing patterns she found.[12]

 Back to the Future is being cited as a key fashion inspiration, it will come as no surprise to any fans of the film or, indeed, of fashion.

 So much so, in fact, that Eastpak is reissuing the original rucksack Marty travelled through time with this season, sold exclusively at Selfridges (although if you have a DeLorean, you are advised to time-travel and buy one of the 80s originals, as Eastpak is certainly not selling them now at 80s prices).

 Marty rocking double denim and high-tops

 Marty himself has been something of a hipster template for a while now: the double denim, the checked shirt, the high-tops. If only Marty had arrived in east London 2014 as opposed to Hill Valley 1955 (and, later, 2015 and 1885), he would have fit right in and instantly sparked a sleeveless parka revival.

As for the other characters, 

Lorraine Baines (later McFly, then Tannen) has, waist up, a proper Alexa Chung look going on, with her Peter Pan collars and demure little jumpers.

Biff Tannen's sports jackets are definitely in style, for men and women, while George McFly's thick-rimmed glasses have been a fashion staple since the dawn of time (maybe alittle exaggeration there)

As for what Back to the Future fashion pieces the biggest vote has to be for Lorraine's wacky 1955 hairstyle, in which her hair zigzags across her forehead

And honestly? Yeah. The clothing is superb. It doesn’t feel costume-y or try hard like The Great Gatsby or Gangster Squad; in BTTF, the period looks are natural yet interesting, feeling cool but dated.

As this film was made in the 80s, that the period they were parodying (1950s) wasn’t that historical.  It was like (literally) looking at pictures your parents wore and checking local thrift stores for clothing ideas.

This all probably contributes to why Hill Valley in 1955 feels real and not filled with some wise-cracking gangster with a down-on-his-luck shoeshine kid.

Clearly, there is a huge difference between menswear in 1955 and 1985, but there are just things that make the 1950’s stand out when compared to other eras, but the 1950’s was a remarkably different than the 1940s.

In this post war time, you had the first inklings of true casual style.  Instead of sportcoats as sportswear, you had dedicated garments like Hollywood jackets.

Shortjackets with point collars and bomber styles were extremely popular to wear when you were off work or just a youth. 

Jeans and converse were the new go-to for casual pant/shoes, though a few still wore pleated

Hollywood waist gab slacks and derbies. And let’s not forget the explosion of prints (tiki and atomic) and tone-on-tone variations that made sportshirts truly “sporty”.

People today call it the Bold Look for tailoring (due to the heavy shoulder pads and dropped button stance) and Rockabilly for casual style.  Either way, it’s pretty cool.

Good examples of the fun casual shirts in the 1950s.

Short jackets of all kinds were common, this time done with fun details.

Great shirts and an epic trouser to boot.

Ties in the 1950’s were more about abstract vertical designs.  Some were slim, others were wide.

Leisuire jackets were all the rage.

BTTF gets all of this right, presumably by the use of true vintage (since the patterns and designs are really specific) as according to the wiki, they only used whatever was in Universal’s costume warehouse. 

However, warehouses could definitely still make good reproductions!   We’ll never know what is true vintage or not, but I’m leaning on the use of true vintage pieces  since would only be 30 years old and wouldn’t be hard to source and get in decent condition.

Marty McFly

We all know Marty McFly’s epic 1985 look. Denim jacket on slim high waisted jeans, with a solid colored crewneck under a button up shirt; we also can’t forget the  life preserver and white/red Nike Bruin sneakers.  It’s a classic outfit that isn’t actually out of place today, since you could wear it at a Halloween costume or as a generic dude in LA (maybe lose one of the layers though).

That period paved the way for “non-traditional” garment mixing that ushered in the current way we approach casual style. Since this is only 15 years from the period of overalls with oxfords or puffers and military chinos, it’s no surprise that wanna-be rocker Marty McFly would also wear something as weird.

However, as we saw in the movie, he stuck out like a sore thumb when he was accidentally sent back in time to 1955.  Luckily with a rich heir like Doc Brown as a friend, Marty is able to get some period accurate clothes and fit into this iteration of Hill Valley.

Marty’s first look for a new day in 1955 is a damn good one: every piece is so great.  Firstly we can see the two-tone leather-gab jacket with a point collar.  Two-tone jackets were popular as youth novelty wear.  I’m pretty sure the one in the film is a reproduction, but if you found that as vintage it would be worth a lot. 

Underneath the jacket, Marty has a block motif sportshirt that he’s rolled up his sleeves a la James Dean. Patterns like this are what make this era’s shirts so much fun.

He has white socks and penny loafers!

With the shirt, he finishes this perfect 1950’s casual-youth outfit with (presumably) pleated hollywood waist slacks that seem to be made of some silk or rayon blend.  providing crunchy/shiny texture that fits in with the era’s obsession with patterns and atomic themes.

Overall, it’s a great uniform to do: sportshirt + high rise trousers + casual jacket. Marty wears the look well, with everything fitting perfectly. In fact, this vibe not only informs some of the looks you can see at Inspiration LA It may not be atomic or tiki, but alohas are certainly in full force in today’s spring/summer.  Even the thin belts are coming back.

They need to make prints like this again!

When Marty gets into the epic skateboard chase, he retains the two-tone jacket but brings in a new shirt and pant combo.  The shirt, now a red/blue piece with a wild diagonal stripe mixed with oversized squares is an EPIC one.  Its a bold pattern, which again makes the 1950’s unique in it’s choice of casual patterns. It just has that retro appeal that I think would look great under a sportcoat, if there were just makers that had it (since a true vintage one would no doubt be expensive).

Note here that he’s now wearing some straight cut blue jeans. It’s different than his slightly acid-washed ones from the 80s, mainly in how it drapes. They’re not overly wide, but moderate, ending with a cuff.  They look how I want my jeans to fit with proper drape. Again, Marty kills it.

At some point, Marty swapped his Corteze with black converse. Looks very 50’s when worn with cuffed blue jeans.

Another fun gab sportshirt that is worn untucked with a white undershirt base layer.

Note the two-tone coloring. Very 50’s.

His last major 50’s look is a sportcoat-trouser combo, worn to the Enchantment Under the Sea Dance. We don’t really get a good look at the full cut or details, so we’re left wondering if this is a true 50’s jacket (or designed like it) or something from the 1980s that they tried to pass off.

The choice of odd trouser, a charcoal grey fleck Again, this was a time of exploring fabrics and cuts in the realm of tailoring, and while illustrations may keep everything clean, photographs from the era showed that the youth always had a mishmash of things.  It’s probably because they didn’t have dozens of trousers to begin with.

The wide cut may be inspired by the zoot suit (Marty does reference it in the film, but zoot suits were more of a 40s thing IIRC), but he rocks it all the same. 

Since you get to see it in full force (along with white socks and black two-tone derbies) while he’s playing the guitar, perhaps it’s his way of exuding that rebellious rocker chic in 1955. He certainly stood out amongst the crowd!

Doc Brown

We don’t really get to see much of Doc Brown’s attire until Marty goes to visit him in 1955; Doc is just in a white jumpsuit in the  Lone Pine Mall. 

When Marty visits him, Doc seems to wearing a variation on what we’d expect a well-to-do heir would wear at home.  A pink shirt (the 1950’s loved color, if you couldn’t already tell) and a white single stripe tie are fun nods to the fact that he’s an adult, but you get the affluent charm with an epic silver dressing gown.

With a scale-esque texture and it’s moderate black satin peak lapels (echoed by the pocket piping), it definitely has that post-war fun vibe.

When Doc goes with Marty to Hill Valley High to check out Marty’s parents, Doc has on a very typical “casual man” outfit.  The tiki shirt is a no brainer at this point, but note the cool gab jacket he has on. 

It’s definitely some form of leisure jacket with modest lapels, patch pockets, and a fun little monogram on the patch.  Jackets like this were casual but they clearly took after the classic sportcoat design; it looks smarter than simply wearing a leather jacket or gab short jacket.

Also take note of his straw fedora (I don’t think it’s technically a panama hat). Instead of the traditional black band, he instead has an abstract design as a ribbon, which was a common trend in the 1940s-1960s for straw hats.  It also just makes the hat much more casual, which is one of the reasons why it’s hard to wear fedora-type hats often.

Flecked trousers. The 1950s loved fleck.

A checked asymmetrical sportshirt with a yolked pocket flap.

Look at Doc’s weird shirt! Super cool and novelty style that was popular in the late 40s-50s.  Finding one today would be rare and expensive.

Doc Brown’s last outfit in 1955 is hard to make out, as he wears an balmaccan style rain coat for the climax, but his polo-style shirt deserves some recognition.  Like so many other pieces we’ve seen, the shirt features a fun print, consisting of red and black squiggles.

The shirt has a contrast collar/placket and cuffs, which again fits in with many of the stylistic choices of the era. I’m not sure if I would wear it today, but more brands should definitely take a page out of the era and make something “new”!

Marty’s dad, at least this version of him, dresses like a dweeb because he is a dweeb.  It’s supposed to be 1985, where RL and other mall clothes are in full swing, and yet he dresses like a caricature of a 1960’s accountant.

Short sleeve shirt, repp tie, pen pockets, and browline glasses, all contribute to it.  I mean I’ve worn socks and shorts together, but I don’t think it looked this bad.

I mean, it makes sense since the film is portraying George as someone who is unlucky, who gets bullied, and gathers no respect.

A flecked short jacket.

In 1955, George McFly actually dresses pretty decently! He’s not exactly sticking out like a nerdy sore-thumb. Like Marty, he wears a few different sportshirts and short jackets, though in comparison, they’re much more plain.  George could also benefit with a better fit, but it’s not terrible.  At least in most cases.

What George does make a habit of doing is wearing his sportshirts fastened all the way to the top. Now this was done back in the day, but based on photos and illustrations, sport collars were definitely best worn open. 

It’s a nerd thing to do that came back in the mid 2010s as the “air tie” and always results in the wearer looking “closed up”.  And since George is a nervous guy with no friends or confidence, it works perfectly.

I like the checked cloth and red buttons.

In one scene, George actually wears a two-tone Hollywood Jacket! Like with Doc’s ivory jacket, these are meant to be a casual-yet-tailored approach to casual wear.  You’ll see that the cut and design are similar to a chore coat’s, just with shoulder pads and “formal” cloth.

George’s brown gab short jacket has shoulder pads and is a size or two too big for him. Also see how he’s got his shirt buttoned all the way up.

An interesting cotton short jacket with a wider collar and hand warmer pockets.  Very cool.

George goes all out for the dance, mainly because it’s his big moment to “save” Lorraine.  A white dinner jacket and black tie is hard not to separate from James Bond (or Casablanca), and its actually the first time George wears something that fits him well.  It’s still in the 1950’s aesthetic, so he has padded square shoulders, a low button stance, and  closed quarters.

When we return to good ol’ modified 1985, accounting-nerd George has been replaced by a true chad version. There are no short sleeve shirts and browline shades here.  Instead, he has a very 80s biz-caz outfit consisting of a moleskin blazer, vibrant red polo, and pleated slacks.  It’s not bold, but since this is a “normal” outfit, it contrasts against George’s first appearance.I also love the aviators for max 80s cool.

Biff Tannen

Biff.  When we first see him, his commandingly bold 70’s outfit just screams like a guy who peaked in high school and still bullies others.  Which is definitely true.

It’s such a weird look that actually has some prep vibes to it, mainly with the use of a navy brass button blazer and plaid odd trousers; I think I may even see a white braided belt.

1985 Biff actually dresses rather “normal” for the era, though he stands out for his boisterous character and sheer Kingpin-like aura.

It’s all just sportshirts, white crewneck tees, and jeans, nothing to write home about. but with it just being done with jeans and sneakers, it feels boring, mainly because its an easy way to do a 1950s look. It’s easy to replicate, but don’t forget that a sportcollar makes a world of difference; a regular standing collar wouldn’t achieve the same effect.

I guess the point is that Biff is just a regular old bully, contrasting against George’s plain looks that utilize jackets and Marty’s much more interesting take on the era.

Biff’s jacket of choice is a bomber style one that has black contrasting collar and cuffs. Can’t you see how popular two-tone clothing was in those days? Like Marty’s leather jacket, this one also ends around the waist, but instead of it just being a plain bomber design, Biff’s jacket has decorative front pleating.  Don’t ask why, it’s just for show.

Like with the shirt patterns, I wish we also had more vintage-inspired jackets like this!

A black shirt and bold tie? I guess stereotypical prom style was a thing even in 1955.

Others

Strickland has a bowtie and suit, but if you look closely, the suit is very 80s with wide shoulders, open notch and low buttoning point.

In 1955, he has a suit that clearly has more weight and features a fun shadow stripe, a common thing for vintage suits.

Ivy style isn’t really in the film other than the committee deciding on the band.  80s ivy is just like 70s ivy tbh: just a more exaggerated and bold version of 60s ivy.

Goldie Wilson also wears a bar motif sportshirt, though with the wide collar, it might be from the 40’s. That makes sense, since he might not have access to current fashions.

Lorraine’s dad wears a car coat (an overcoat with a shorter length). He has a fedora, which gives him an “adult” look. Not sure if the trouser fit is right though. 

As can be expected, Lorraine’s dad has a gab sportshirt.  The shorter collar points and higher buttoning point is period accurate to the 1950s.

So much great stuff here, from the faded, cuffed denim and saddle shoes to the absolutely epic novelty knitwear.  I’m very glad that the youth have a variety of style! 

Striped shirts are what kids wore back then, not flat caps, plus-fours, and suspenders. 

Biff’s gang all have variations on casual style.  Is that a knit tee I see? Wish we could see the ribbing!

More variety in style here and it all looks period. Love the kid’s pastel blue pleated pants, the red sweater, and what I think is a Cub Scout uniform. Check out that tiny brimmed hat!

Marvin Berry and the Starlighters all wear 50’s silk dinner jackets with their quintessential square shoulders and low button stance.  Instead of bowties, they have matching continental bow ties.

Great short jacket.

Conclusion

BTTF is a great example of a movie that makes 1950’s clothing seem accessible and easy.  There isn’t a big focus on tailoring, which probably makes it much more palatable. Instead, we see casual 50’s, rockabilly-esque style, which informs a lot of the heritage-Americana that is so easy for guys to wear. Sportshirts and cuffed jeans should get you through the most of it.

The real way to make it interesting is by checking out how Marty does it. Instead of plain shirts, he wore fun patterns that made his attire stand out among the others.  It might be vintage and dated, but I certainly love the personality they bring to an outfit, especially since today you can refine it by wearing with loafers or a sportcoat instead of on its own. 

Bonus points for those epic two-tone jackets (or leather jackets in general). I’m not sure if the world is ready for the return of hollywood jackets, but after the rise of chore coats and safaris, maybe there’s room for it.

Overall, I think a lot of guys who are searching for a more interesting way to dress can take some cues from this.  BTTF did a great job and since it didn’t go too crazy (note the lack of flat caps, which if included would just be inaccurate), it comes off as classic and actually wearable.

I love this movie and I hope you enjoyed this dive into the costuming

Always a pleasure,

Ethan M. Wong

Hill Valley - ‘Back to the Future’ History

Hill Valley Is the fictional town in California that serves as the setting of the Back to the Future trilogy.

Hill Valley Clock Towner - Back to the Future set

 In the trilogy, Hill Valley is seen in four different time periods (1885, 1955, 1985 and 2015) as well as in a dystopian alternate 1985.

 The films contain many sight gags, verbal innuendos and detailed set design elements, from which a detailed and consistent history of the area can be derived.

 The name "Hill Valley" is a joke, being an oxymoron. However, an early script for Back to the Future Part II mentioned that Hill Valley was named after its founder, William "Bill" Hill.

Production

For Back to the Future, the producers considered filming the town square scenes in the real city of Petaluma, California, but soon realized it would be prohibitively expensive and impractical to alter a real place to suit the different eras.

Instead filming was completed on the Universal Studios backlot, where they had more control. 

Hill Valley - Back to the Future set

 The town square set, once called Mockingbird Square after the 1962 film To Kill a Mockingbird but now known as Courthouse Square, had been used for many films and television shows dating back to 1948's An Act of Murder.

One notable example is the very first episode of the sci-fi series The Twilight Zone, called "Where Is Everybody?" in 1959.

 The Hill Valley courthouse can also be found in the movies Bruce Almighty, Gremlins, Bye Bye Birdie, Sneakers, The Offspring's music video "Why Don't You Get a Job?", an episode of Major Dad entitled "Who's That Blonde" and even in an episode of Buffy The Vampire Slayer.

Gremlins Set

Gremlins Cinema - (Remember the DeLorean crashing into it !)

 The clock tower itself was a removable addition, one of many ways in which the Courthouse building has been redressed over the years to suit the needs of a production.

 Many of the cars that appear in the 2015 scenes are either modified for the film or concept cars.

Hill Valley Sign 2015

Examples include Ford Probe, Saab EV-1, Citroën DS 21, Pontiac Banshee Concept, Pontiac Fiero and Volkswagen Beetle. Cars reused from other science fiction films include the "Star Car" from The Last Starfighter (1984) and a "Spinner" from Blade Runner (1982).

Griff's car is a modified BMW 633 (which was notably never in the convertible form seen in the film).

 For Back to the Future Part III, Hill Valley 1885 was filmed in Sonora, California. The producers were able to use the land rent-free under an agreement to leave the set buildings on site.

 All buildings except the clock tower were left intact after production completed.

 ! On November 6, 1990, an arson fire on the Universal Studios Hollywood backlot destroyed much of Courthouse Square, the setting in which all the other time periods were filmed.

 However, the Courthouse itself survived the devastation and other facades were reconstructed.

 ! Another fire on September 6, 1997 again damaged Courthouse Square. Once again, the backlot facades were then rebuilt, with the exception of the facades used for Hill Valley 1885.

 ! On February 14, 1999 fire at Whittier High School, California, where some (mostly exterior) scenes were filmed, destroyed the men's gym there.

 ! On June 1, 2008, yet another fire destroyed part of the rebuilt Courthouse Square backlot and damaged the clock tower.

Real-life locations

Other real-life shooting locations of Hill Valley landmarks include:

·         Doc's house in 1955 is the Gamble House in Pasadena, California. Doc's garage in 1985 was a façade set up next to a Burger King on North Victory Boulevard in Burbank, California.

Doc Brown House

·         Twin Pines/Lone Pine Mall is actually the Puente Hills Mall in Industry, California.

Lone Pine Mall

·         Marty's Lyon Estates house in 1985 is actually at 9303 Roslyndale Avenue, Pacoima, California.

Marty McFlys House

·         The 1955 Lyon Estates field is actually along farmland between the city borders of Chino, California and Corona, California.

Lyon Estates

·         Peabody's Twin Pines Ranch is really at Golden Oak Ranch, which is owned by The Walt Disney Company and used in many Disney productions.

Peabody on his Ranch

·         The houses of George McFly, Lorraine Baines, and Biff Tannen in 1955 are all in South Pasadena, California.

·         The train that hit the DeLorean and the Futuristic Train was parked in Port Hueneme, California.

·         John F. Kennedy Drive is actually Victory Boulevard in Burbank, California.

·         The River Road Tunnel is actually Observatory Tunnel at Griffith Park in Los Angeles. The actual tunnel is only a fraction of the length of the one depicted in Part II.

·         The Pohatchee Drive-In Theater where Marty initially travels from 1955 back to 1885 was not a real theater. It was constructed full-scale for the third film in Monument Valley, Utah (near the Arizona/Utah border) and was torn down after that portion of filming was completed.

·         Marty's race with Needles was shot on Doris Avenue in Oxnard, California.

According to an 1885 railroad map in Back to the Future Part III, Hill Valley is located in Northern California in the Sierra Nevada Mountains. Dialogue in Back to the Future Part II and Back to the Future Part III places it in "Hill County", a fictional county in California.

Fictional history

The following information is taken directly from places and events shown or mentioned in the three films:

Early settlement

The town of Hill Valley is depicted as having been first settled in 1850 and incorporated in 1865.

By the 1880s, it was connected by railroad to San Francisco. Construction of a new county courthouse was well underway in 1885, the setting of Back to the Future Part III, in which a new clock was dedicated for the building.

 The Shonash Ravine Bridge was completed in the summer of 1886, around the same time the ravine was renamed Clayton Ravine in memory of Clara Clayton, a school teacher who died from falling into the chasm.

However, in a revised timeline where Doc Brown saved Clara's life, the town renamed it Eastwood Ravine after Marty McFly's persona when it is believed that "Eastwood" fell into the ravine while trying to stop some train hijackers (who are really Marty and Doc).

Town square

By 1955, as seen in the first two Back to the Future films, the area around the courthouse has developed into the downtown of Hill Valley.

 In front of the courthouse is a grass-covered town square, with stores, two movie theaters (Essex and Town), and cafés on the surrounding streets.

 A key moment in the town's fictional history takes place on Saturday, November 12, 1955, at 10:04 p.m. PST, when lightning strikes the courthouse's clock tower, freezing the clock at 10:04.

Hill Valley lighting strike

The clock is never repaired and becomes a local landmark, left in its non-functional state at the behest of the Hill Valley Preservation Society.

Hill Valley Preservation Society

 The broken piece of ledge from Doc Brown's successful attempt to channel lightning from the clock tower is likewise never repaired, as can be seen when Marty returns to 1985 and in 2015, but not in the Alternate 1985.

 In Marty's original timeline, many of the town square businesses have moved or closed down by 1985.

 The new businesses which replaced them include a second-hand shop, a yoga studio, and an adult book store.

The Essex movie theater now shows porno movies while the Town Theater is used for church services, and the courthouse is in a state of disrepair, and at night at least one homeless person (called "Red" by Marty) sleeps on the town square park benches.

 The grassy park outside of the courthouse has been converted into a parking lot. "That was always one of the major elements of the story even in its earliest incarnation," screenwriter Bob Gale says in The Making of Back to the Future, "was to take a place and show what happens to it over a period of thirty years.

What happened to everybody's home town is obviously the same thing. They built the mall out in the boonies, and killed all the business downtown, and everything changed.”

 By the 21st century, the downtown area has experienced a revival as the courthouse has been converted into the Courthouse Mall.

Hill Valley 2015

Businesses have begun to move back into and around the town square and the parking lot has been replaced by a pond.

The clock on top of the courthouse is still preserved at 10:04, and the mall's logo is an illustration of a lightning bolt striking the clock tower.

The Town Theater / Assembly of Christ building has been converted to an art museum with a mural painted on the front side of the building above the marquee.

Signs that say "Welcome to Hill Valley" are seen in 1955, 1985 and 2015.

Welcome to Hill Valley

Both 1955 and 2015 signs have symbols representing the Rotary, Kiwanis and Lions clubs. In addition, the 1955 sign has the logos of the YMCA, Jaycees, and Future Farmers of America while the 2015 sign has those of the Neighborhood Crime Watch eye logo and the 4-H Club clover logo.

 The "Welcome to Hill Valley" sign in 1985 does not contain any signage representing any clubs and mentions the name of Mayor Goldie Wilson.

 In the alternate 1985 Marty is seen walking over the sign, which has been knocked down and an 'E' has been spray painted over the 'I' in HILL VALLEY making the name HELL VALLEY. 

Welcome to Hell Valley

This sign does not display the name of the mayor but instead the words "A Nice Place to Live" as also seen in 1955. A sign referencing US Highway 395 is also shown next to the Town Square in 1955.

Hill Valley 1955

Hill Valley 1955

 Twin Pines Mall (Lone Pine Mall)

 Twin Pines Mall is a shopping center located outside Hill Valley, where Doctor Emmett Brown first tests his time machine, making his dog Einstein the first time traveler in the world.

Lone Pine Mall

The site where the mall was filmed for the movie is actually Puente Hills Mall, located in City of Industry, California. The J.C. Penney location seen in the movie had been shut down, and is now occupied by a 24 Hour Fitness center.

The mall's name changed to Lone Pine Mall after Marty went back to 1955, because he accidentally destroyed one of the two baby pine trees for which it was named as he fled an irate Old Man Peabody whose barn the DeLorean had crashed into upon arriving in 1955.

Alternate history

In Back to the Future Part II, a nightmarish alternate version of Hill Valley (dubbed 1985A by Doc) is depicted complete with a partial history. Due to the influence of the powerful and corrupt Biff Tannen, gambling was legalized in 1979. Tannen's toxic waste reclamation plants were built downtown, polluting the air and leading to pollution alerts to be issued.

All of the local businesses in the downtown area closed or relocated and were replaced with strip clubs, porn theaters, and brothels. Tannen also bought off the police.

Hell Valley Biff Tannen

Consequently, crime increased and biker gangs settled in the city. Hill Valley's public schools burned down and the courthouse was converted into Biff Tannen's Pleasure Paradise Casino and Hotel. The clock on the courthouse still remains at 10:04 although despite the damage the Doc did to the tower's platform in 1955, for whatever reason, it now seems to have disappeared.

Hill Valley Clock Tower

Biff also murdered George McFly (Marty's dad) in 1973 so that he could marry George's wife Lorraine (Marty's mom) therefore making him a corrupt family man as well as town ruler. He also helped Richard Nixon remain President of the United States until at least 1985. Biff's effect on history affected the whole world – in this version of history, the Vietnam War was also still ongoing by May 1983.

According to the original script for Back to the Future Part II a partial view of the alternate 2015 was also to be depicted. By this time Biff now owns half the state of California with his influence having gained his son, Biff Jr., the seat of governor and they uphold their power and corruption with an army of large, powerful cyborg police officers.

Hill Valley Business

Many family businesses are passed down from generation to generation in Hill Valley. As a result, the city changes but remains similar from one generation to the next, as businesses are updated but rarely change. These recurring elements were a deliberate choice on the part of the filmmakers.

The production designer of Back to the Future Part II, Rick Carter, is quoted in a DVD extra as saying, "The future is built on the present." Director Robert Zemeckis adds that the continuity between the different eras in Hill Valley's history is an example of the adage, "the more things change, the more they stay the same".

The following is a list of such places. When a place is not seen or mentioned in a movie, it is marked unknown. Some buildings shown in 1885 scenes are actually located further down the street in an area not shown in the first two movies.

Ghostbusters Ecto 1C Hits the Streets !

Ready for some Ghostbustin action ?

We are so please to announce the completion of our very own Ecto 1 C Ghostbusters Car

Ghostbusters Ecto 1C Experience

Our meticulously crafted modern replica of Ecto 1C is a testament and dedication to the Ghostbusters franchise and its enduring legacy.

“Our inspiration for building this Ecto 1C came from many different places, firstly from already building a DeLorean Time Machine. This gave me the inspiration to look at another one of my favourite film franchises Ghostbusters.

Consulting the option of fellow Ghostbusters who asked the question :

What car would the Ghostbusters Drive today…..?

Everyone in the States pointed to the Dodge Magnum (here in the U.K it would be the Chrysler 300c). As this platform of vehicle has been used for police cars and other emegency vehicles due to the size and larger engines.

So work set out to find one….. Many years rolled past, and working progess was delayed by working out how to power up and make the equipment operational. Also here in the U.K 300c’s in white were not sold, which meant it needed to be completely resprayed.

Fast forward to June 2024 and Ecto 1 C was finished complete with P.K.E Meter, Ghost Trap, Portable Containment unit, Proton Packs, emergency lighting, and siren just ready for the 40th anniversary of Ghostbusters !

Why ?

Knowing there’s so many Ghostbusters fans out there (and now driving our Ecto 1C around the streets I’ve found there are many more people that love the Ghostbsusters) I wanted to bring the enjoyment of the Ghostbusters to all the Fans.

Being able to actually provide this amazing experience of having an Ecto 1 for real on their drive, or out in patrol in one, and seeing that smile makes this a fantastic experience.

Ecto 1C is available for Weddings, Partys, conferences, events, special occasions, Birthdays and much more !

Time Machine - Operators Guide - DeLorean

Back to the Future DeLorean Time Machine … Operators Guide.

The #DeLorean #timemachine is a fictional automobile-based time travel vehicle device as featured in the Back to the Future franchise.

Operation of the #DeLorean #Timemachine

The main operation of the time machine is the same in all three films. The operator is seated inside the DeLorean (except the first time, when a remote control is used), and turns on the time circuits using the Time Drive Switch, this activates a unit containing multiple fourteen- and seven-segment displays that shows the :

• Destination Time and Date (Red),

• Present Time and Date (Green)

• Last-departed Time and Date (Yellow)

Enter in your own Time and Date into the TIme circuits using the keypad below the unit so, if you wanted to travel to 5th November 1955 at 6.00am you would enter :

11 05 1955 0600 then press enter.

The Plutonium Gauges will power up at the same time as the Time Display. After entering a target date, and with the Time Drive Switch is left on, the system is active. Once the operator accelerates the car up to #88 miles per hour (141.6 km/h), the flux capacitor actives……(and the rest is History !)

As it accelerates, several coils around the body glow blue/white while a burst of light appears in front of it as it enters the wormhole (see our ‘Is Time Travel possible’ blog)

Surrounded by electrical current (similar to a Tesla coil), the whole car vanishes in a flash of white/blue light seconds later, leaving a pair of fiery tire tracks.

A digital speedometer attached to the dashboard allows the operator an accurately gauge of the car's speed.

Observers outside the vehicle see an implosion of plasma as the vehicle disappears, while occupants within the vehicle see a quick flash of light and instantaneously arrive at the target time in the same spatial location (relative to the Earth) as when it departed.

Time Machine - DeLorean Dmc-12

Hover Conversion - The DeLorean Time Machine

In the destination time, (immediately before the car's arrival), three large and loud flashes occur at the point from which the car emerges from its time travel (at the speed of Sound, the Sonic Boom). After the trip, the exterior of the DeLorean is extremely cold, and frost forms from atmospheric moisture all over the car's body and thermal heaters on the back of the vehicle.

A few technical glitches with the DeLorean that could hinder time travel for its users :

In the first film, the car has starter problems and Marty McFly has a hard time restarting once stopped, much to his repeated frustration.

In the second movie, the destination time display malfunctions and shows random dates (mostly January 1, 1885), which partially cause Doc to be sent to 1885.

In the third movie, the flying circuits (added by Doc in 2015), fuel line, and fuel injection manifold are damaged, preventing the car from moving under its own power

In the feature film series, Dr. Emmett L. Brown builds a time machine from a retrofitted #DMC DeLorean car, to gain insights into history and the future. Instead, he and Marty McFly end up using it to travel across 130 years of Hill Valley history to change the past for the better and to undo the negative effects of time travel.

The car requires 1.21 gigawatts of power, and needs to reach 88 miles per hour in order to operate the Time Machine circuits so it can time travel. The official Back to the Future DeLorean (named the A Car) can now be viewed at the Petersen Automotive Museum

Reactor Core - DeLorean Time Machine

Hill Valley Clock Tower - Back to the Future

#DeLorean Power ..... !

The time machine circuits are electric and require a colossal power input of 1.21 gigawatts (1,620,000 hp) to operate.

Originally provided by a plutonium-fuelled nuclear reactor (in the first movie), #DocBrown has no access to plutonium in 1955, so he outfits the car with a large pole and hook in order to channel the power of a lightning bolt into the #FluxCapacitor and send #Marty back to 1985.

During Doc's first visit to 2015, he had the machine refitted to Hover above ground in addition to standard road driving, and he replaces the nuclear reactor with a Mr. Fusion generator that uses garbage as fuel.

Mr Fusion - Home Energy Reactor

DeLorean Time Machine - Being pushed by steam locomotive

Although the #MrFusion unit provides the required power for the time machine, the DeLorean is still powered by an internal 2.8 V6 PRV combustion engine for propulsion.

This caused a problem when the fuel line was damaged during Marty's trip to 1885 in Back to the Future Part III; after he and Doc patch it, they attempt to use whiskey as a replacement fuel since commercial gasoline is not yet available.

The test fails, damaging the car's fuel injection manifold and leaving it unable to travel under its own power.

Doc and Marty consider options to reach the required 88 mph such as :
Pulling it with horses, which fails because the car barely breaks 20 mph) but ultimately settle on pushing the car with a steam locomotive.

For the extra power needed to push the DeLorean up to speed, Doc adds his own version of "Presto Logs" (a chemically treated mixture of pressed wood and anthracite) to the locomotive's boiler and chooses a location with a straight section of track long enough to achieve 88 mph

Presto Logs - Back to the Future

The power required is pronounced in the film as one point twenty-one "jiggawatts".

While the closed-captioning in home video versions spells the word as it appears in the script, jiggawatt, the actual spelling matches the standard prefix and the term for power of "One Billion Watts": Gigawatt. Although rarely used, the "j" sound at the beginning of the SI prefix "giga-" is an acceptable pronunciation for "gigawatt."

Back to the Future - Detailed Storyline

Doc Brown and Marty McFly - Credit to Universal Picture Amblin Entertainment

Back to the Future Detailed storyline - It all started when…

Marty: "Wait a minute. Wait a minute. Doc, uh... Are you telling me you built a time machine... out of a DeLorean?"

Doc: "The way I see it, if you're gonna build a time machine into a car, why not do it with some style? Besides, the stainless steel construction makes the flux dispersal- look out!!!"

— Doc and Marty during the first test

The DeLorean time machine was Dr. Emmett Brown's most successful invention, a plutonium-powered time machinecomprised of a DeLorean DMC-12 sports car that had to reach 88 miles per hour in order to time travel.

On November 5, 1955, Doc was standing on the edge of his toilet, while hanging a clock in his bathroom. But the porcelain was wet, making Doc slip, fall and hit his head on the sink. When Doc came to, he had a vision of the flux capacitor in his head, and drew a crude schematic diagram as well as scrawling some hurried calculations. The capacitor was constructed afterward and completed in 1985.

Hill Valley Telegraph

History

Doc purchased the DeLorean DMC-12 from a seller named Robert, who had advertised it in the classifieds section of the August 11, 1984 issue of the Hill Valley Telegraph.

BACK

The first test

Main article: World's first temporal displacement

Doc and Marty stand in the fire trails left behind by the DeLorean on the first test.

Doc Brown revealed his creation to his friend Marty McFly at Twin Pines Mall, in the early morning of October 26, 1985, and for its first test, Doc sent his dog Einstein one minute into the future. The sequence of events that followed were as so; after Doc revved up the engine to 65 m.p.h. while braked, he released the brake sending the car towards Doc and Marty.

A faint glow developed at the front of the car and then engulfed the vehicle. The coils lit up, internal circuits glowed, and the flux capacitor fired rapidly. Suddenly the car seemed to explode just before it hit Doc and Marty. Fire trails then scorched the pavement where the vehicle would have passed through, completing the temporal displacement sequence.

Marty: "Jesus Christ, Doc. You disintegrated Einstein!"

Doc: "Calm down, Marty, I didn't disintegrate anything. The molecular structure of both Einstein and the car are completely intact!"

Marty: "Well, where the hell are they?!"

Doc: "The appropriate question is "When the hell are they?" You see, Einstein has just become the world's first time traveler. I sent him into the future! One minute into the future to be precise. And at exactly 1:21 A.M. and zero seconds we will catch up to him and the time machine."

— Doc and Marty after the time travel experiment.

For Einstein, the trip was instantaneous, but to Marty and Doc they had to wait exactly one minute to catch up to Einstein in the timeline. In the meantime, Marty asked why a DeLorean was used. 

Doc explained that it needed some style and implied that the stainless steel construction of the car helped it in temporal displacement. But Doc didn't fully explain why because the watch he was wearing at the time beeped, warning him that the DeLorean's return was only seconds away.

The car suddenly appeared where Doc and Marty were standing and screeched to a halt as a frozen shell. Supercooled from traveling through time, the gullwing door was troublesome for Doc to open while using his hands. Inside the car, Einstein was unharmed, much to the surprise of Marty. Doc then showed Marty the interior and its controls.

"First, you turn the time circuits on. This read-out tells you where you're going. This one tells you where you are. This one tells you where you were."

—Doc Brown

While inputting dates on the keypad, Doc used July 4, 1776 (the date the American declaration of Independence was signed) and December 25, 0000 (the date of the birth of Christ) as examples, before inputting "a red-letter date in the history of science, November 5, 1955". From there he left the cockpit of the DeLorean and reminisced about the past, particularly about Old Man Peabody owning the land that is now Twin Pines Mall and his pine tree farm.

"My, things sure have changed. I can remember when this was all open land as far as the eye can see. Old Man Peabody owned all of this. He had this crazy idea... about breeding pine trees."

—Doc talking to Marty

Trapped in 1955

Soon after a new pellet of plutonium was inserted into the time machine, the Libyans who he stole the plutonium from intervened in a Volkswagen and shot Doc dead. Marty ran into the DeLorean to try to escape the Libyans. Marty accidentally turned the time circuits (still set to 1955) on while shifting, and as he avoided being destroyed by a rocket-propelled grenade, he sped up to 88 and entered temporal displacement. Suddenly, Marty went from a mall parking lot in 1985, to a field in 1955, and the DeLorean crashed into a scarecrow and then the Peabodys' barn.

A radiation suit-clad Marty trips as he leaves the DeLorean.

"It looks like an airplane... without wings."

Doc Brown and the Time Machine

—Otis Peabody

For a moment, Marty was stunned, and the Peabody family ran from their house to the barn to investigate. Believing that the vehicle was from another world, they screamed in horror as Marty lifted the gullwing door and stepped out, dressed in a radiation suit. Marty was almost shot from the buckshot of Otis Peabody's shotgun, and ran back to the safety of the time machine, floored the accelerator, and smashed through the doors of the barn. After escaping from Peabody's shotgun, the car ran over one of the two pines that Peabody had been growing. This was the first effect of Marty's trip into the past that would alter the future (the "Twin Pines Mall" would become the "Lone Pine Mall"). 

Marty pulled the DeLorean onto a highway that ran by the future site of Lyon Estates. He immediately stopped and viewed the undeveloped land stretch far out into the distance, questioning whether or not it was a dream. A meter in the DeLorean indicated that it was out of plutonium, and the car shut down. Marty failed to get it running again and decided to hide the DeLorean behind the Lyon Estates sign, covered by a few shrubs, and walked the two miles to town.

"It works! Ha ha, it works! I finally invented something that works."

—Young Doc Brown

After convincing the 1955 Doc that he was indeed from the future, Marty and Doc went back to the site to recover the time machine. Doc opened the door and turned on the flux capacitor which he had envisioned after his fall earlier that day. The DeLorean was driven back to Doc's garage where it was hidden under a tarpaulin until the night of the thunderstorm, November 12.

On the 12th, Doc brought the time machine to Courthouse Square in downtown Hill Valley, and started working on the cable assembly that would harness the impending lightning strike. Arriving late, Marty was briefed by Doc, just as the storm moved in and took down a tree. Marty drove the DeLorean to the starting line at the Bluebird Motel, and inserted a tall connecting hook into the flux capacitor. He then waited for the alarm to go off while Doc reconnected the cable, and decided to reset the controls to arrive 11 minutes earlier than scheduled. With that, the engine suddenly died, and left Marty trying to restart it. Marty finally (and unexpectedly) succeeded in restarting the engine after head-butting the horn in frustration, and took off. The DeLorean reached the cable just as the lightning struck, and Doc made the connection, sending the time machine back to 1985.

In 1985, Red the Bum was awoken by the sonic boom of the DeLorean, followed by the sound of a crash at the Town Theater. Marty jumped out of the icy time machine to check out downtown and to verify that he had gotten back to the future, and back to his normal year of 1985. Returning to the car to save Doc, Marty tried to drive off and the engine died once again. This was the last time in the trilogy that it had done so. The Libyans passed him on the street, and Marty ran back to the mall. There, he saw the first DeLorean make the jump to 1955, with the terrorists' van crashing into a photo booth. Originally believing he was too late, Marty was in grief, then surprise. Doc recovered, and revealed that he was wearing a bulletproof vest, having read the warning letter that Marty had written 30 years earlier.

Doc returned to downtown to start the DeLorean up, and drove Marty back to his home in Lyon Estates. Doc told Marty he would go roughly 30 years into the future, "a nice round number". Doc backed the DeLorean up with enough room to reach 88 mph on the street and vanished in three sonic booms.

While in the future, Doc decided to give the DeLorean a now standard hover conversion. To afford this, he traveled back to 1938, and bought several copies of Action Comics #1. He sold them for $2.5 million in 2015, and flew off in the newly converted DeLorean. At some point, he discovered that Marty's children were destined to accidentally go to prison, which would eventually destroy the McFly family.

Doc: "Roads? Where we're going we don't need... roads."

— Discussion between Doc and Marty in the DeLorean before takeoff

The DeLorean lifts off, bound for 2015.

Doc returned to the McFly residence, the morning after he left. Marty had discovered that his life had changed for the better. His visiting girlfriend Jennifer Parker, and he, were interrupted by the sonic boom and wind blast. The newly upgraded DeLorean knocked over some trashcans, and a futuristically-garbed Doc emerged from the vehicle. Doc made use of his upgraded time machine by adding garbage to the Mr. Fusion as fuel. Plutonium was no longer needed after the trip to the future. Doc told Marty and Jennifer of their future family, and the trouble that occurred (or would occur) with their children.

The DeLorean lifted off the ground and its wheels folded providing thrust. The rear louver then propelled it forward down the street, and Doc turned the car around to get the speed needed to make temporal displacement. This entire sequence was witnessed by Biff Tannen in the McFly driveway.

The time machine entered October 21, 2015, then descended through the clouds into a busy skyway, nearly in the wrong lane of multilevel traffic. Doc pulled off onto an exit ramp to downtown Hill Valley. He landed the DeLorean in an alleyway, just outside Courthouse Square, then left while Marty completed his mission to save Marty, Jr. After Doc recovered Einstein from a suspended animation kennel, he pulled the DeLorean out into the open, where Old Biff saw it, and eventually put two and two together to realize that they were time travelers. 

Biff steals the DeLorean.

"Flying DeLorean? Haven't seen one of those in... thirty years"

—Old Biff

Biff followed Doc and Marty in a taxi cab, and while the DeLorean was parked outside Hilldale, Biff stole it and went back to 1955 to hand the Grays Sports Almanac (that Doc had thrown away) to his younger self, thus altering history. In a matter of minutes, Biff returned the vehicle in the same position; however, he was feeling the effects of changing history.

In pain, he left the silver-colored bag and receipt for the almanac, as well as the top of his cane which broke off in the DeLorean when he doubled over. Getting out of view, Biff slumped to the ground and faded from existence behind a parked car. Doc and Marty, unaware that anything had happened, returned to the time machine with Jennifer and headed back for 1985.

An alternate history

"Imagine that this line represents time. At some point in the past, the timeline skewed into this tangent creating an alternate 1985. Alternate for you, me, Jennifer and Einstein...But reality for everyone else."

—Doc showing Marty 1985A on a blackboard.

By this time it was too late to prevent the changing of the timeline. Flying at a high altitude, the DeLorean was nearly hit by an airliner in the sky. The time circuits began to malfunction as well, indicating 1885 temporarily. After discovering the truth behind the alternate 1985, Doc and Marty left Einstein in Doc's garage, and Jennifer at her house, where time would alter around them pending a change in the past. They traveled back to November 12, 1955, the date that Biff revealed to have been the day he had gotten the almanac.

Doc parked the time machine behind the same sign that Marty hid it the first time in 1955. Marty notified Doc of his status with Biff, and after some repairs, Doc jumped into the DeLorean to pick him up at Hill Valley High School.

As Doc left Lyon Estates, the car had hooked onto some of the pennants on the sign. Doc and Marty followed Biff in his car, and hovered over him, until Marty thought of using the hoverboard to get closer. Marty grabbed the almanac after some fighting, but was faced with being in the middle of a long tunnel from which to escape.

At the end of the tunnel, Doc dropped the string of pennants that he had hooked onto earlier, and Marty grabbed the rope in time to prevent himself from getting run over by Biff (who crashed, for the second time in a week, into a manure truck).

Returning to Lyon Estates to destroy the almanac, Doc lowered Marty onto the ground, but deemed it unsafe to land the DeLorean in the storm. Marty successfully burned the almanac in an old bucket, reverting all effects that had been created by 2015 Biff. The celebration was short-lived; lightning struck a tree close to Marty, who warned Doc about getting struck himself. In the next instant, however, lightning struck the DeLorean as feared, spinning it up to 88 mph (thus creating the fire trails in the shape of backward 9's), scrambling the circuits, and sent Doc and the DeLorean back to January 1, 1885[1]

Less than a minute later, a man, representing Western Union, appeared on the rainy street and handed Marty a letter. The letter, from Doc, had been held in their possession for over 70 years, with instructions for delivery to that exact position, at that exact moment, to that exact person — Marty.

Marty ran back downtown, arriving just moments after his other self was going back to the future, and after the temporal displacement, he encountered 1955 Doc, who then fainted.

Marty: "OK, Doc, just calm down. It's me. It's me! It's Marty!"

Doc: "No, it can't be you! I just sent you back to the future!"

Marty: "Yeah, I know. But I'm back. I'm back from the future."

— Marty to Doc before Doc exclaims "Great Scott" and faints.

Delgado Mine - Back to the Future Part 3

BACK

The letter, read the next morning by Doc, stated that the DeLorean was buried in the Delgado Mine, and provided repair instructions on fixing the time circuits with 1955 parts. At the Boot Hill Cemetery, outside the mine, Marty and Doc stumbled onto 1985 Doc's tombstone from 1885. It was now Marty's mission to save Doc in the past, and bring him back to the future as well.

Finding the DeLorean

Doc replaced the rotting tires with new whitewall tires and, working from the schematic diagram provided with the repair instructions, replaced all the broken instruments with 1955-era vacuum tubes and other components. He also put gasoline in the tank, since 1985 Doc had to drain all the fluids from the car, including the gas, before putting it into long-term storage.

The Old West

The DeLorean encounters a tribe of local Indians.

"Marty, you're not thinking fourth-dimensionally. You'll instantly be transported to 1885 and those Indians won't even be there..."

1955 Doc and Marty set up at the Pohatchee Drive-In Theatre, far away from town, so that Marty's arrival would not be noticed by residents in 1885. Doc set the time circuits to the day after his 1885 counterpart sent the letter on September 1. Marty hesitated to drive at the screen because of a wall with Indians painted on it; but as Marty reached 88 mph, the 1955 wall was gone, but was replaced with real, 1885, Pohatchee Indians, who chased after the DeLorean, which Marty hid in a bear cave.

Marty avoided the Indians, and the U.S. Cavalry that was chasing them, but discovered that an Indian had shot an arrow into the engine of the DeLorean. Upon removing the arrow, Marty accidentally tears a hole in the fuel line of the car. He pays it no mind as he is chased out of the cave by the bear living there at the time, and fell down the hill and landed on the property of his Irish ancestors.

The DeLorean was recovered by Doc, but there was no gasoline available in 1885 to replace the fuel that had leaked out. [2]Marty wasn't concerned as he stated Mr. Fusion could refuel the DeLorean. Doc said that was impossible as the engine always ran on gasoline and Mr. Fusion only powered the flux compacitor and the flight circuits. Doc then plotted means of powering the car, including having his horses try to reach 88 mph out in the desert, they only made 30 mph.

Doc received a strong alcohol concoction from the town bartender, Chester, that he hoped would have a similar effect to gasoline, but instead, blew the fuel injection manifold out. This left only one available option: pushing the DeLorean up to 88, which came in the form of a locomotive.

Doc and Marty's plan was to hijack, or borrow,  the locomotive, and take it to an unused spur that ran to Shonash Ravine, where it would push the car before running off the end of the track. On the night of September 6, Doc placed the car onto the track. There, it awaited the locomotive.

Their plan was successfully enacted on September 7, and though Marty was sent back to 1985, Doc and Clara Clayton remained in the past. The DeLorean reached temporal displacement just before hitting the buffer at the edge of the ravine; however the train crashed through and landed into the ravine in a large explosion.

The DeLorean is destroyed by a locomotive.

Back in 1985, the DeLorean traveled along the railroad tracks for about a mile until it came to rest on the track outside Hilldale. Immediately, Marty was stunned to see a modern locomotive barreling towards him, and escaped from the DeLorean just before it was destroyed by the train. After it had passed by, Marty gazed at the time circuits and flux capacitor in shock just as they flickered on and then off for the last time.

"...Well Doc, it's destroyed... Just like you wanted..."

—Marty standing at the remains of the DeLorean

Marty and Jennifer, who had remained on her porch, both went through the wreckage. Then, peculiarly, the railroad crossing's bells sounded and its gates went down. No trains were to be seen. Just then, the Jules Verne Train appeared, and blew Marty and Jennifer back several feet. This was Doc's way to return without the aid of the DeLorean. After introducing Marty and Jennifer to the two new members of the family, Jules and Verne, Doc handed Marty a gift — the photograph of them standing in front of the clock — and gave some words of advice before leaving to times unknown.

"Your future hasn't been written yet! No one's has! Your future is whatever you make of it. So make it a GOOD one!"

Doc Brown - Your Future hasn’t been written yet

—Doc to Marty and Jennifer

Marty: "Where ya going Doc? Back to the future?"

Doc: "No, already been there!"

— Doc and Marty during the final scene of Back to the Future Part III

Just before its destruction, the DeLorean can be seen to have parts from every time period it has been in. Inside the time machine was also a walkie-talkie from 1985A.

Rebirth of the DeLorean

Note: The following section is considered non-canon or is disputed in canonicity.

Six months after the destruction of the DeLorean, another DeLorean time machine, nearly identical to the one used previously by Marty and Doc, appeared outside of Doc's garage. Upon following Einstein's clues to the source of the time machine, Marty drove it back to 1931, where he found Doc in jail for allegedly blowing up a speakeasy.

Doc told Marty that the DeLorean he had been driving was a temporal duplicate, created when the DeLorean was struck by lightning; the original going seventy years back to 1885, and the other version seventy years forward to 2025. Doc went forward in time with the Jules Verne Train, recovered the second DeLorean, fixed it up, and began traveling again. Doc also installed a program that would activate upon Doc not returning to the vehicle within a certain length of time. This automatic retrieval feature allowed the DeLorean to return to a set time and location of Doc's choosing.[3]

Around 1991, Doc Brown and his family returned to Hill Valley in the Train and settled down in the present. Marty had, by now, been attending Hill Valley College, and he visited the Brown family regularly. The DeLorean was rebuilt with added features, including a new audio receptive series of time circuits, submersible capabilities, a pincer, and having the ability to fold into a compact suitcase-sized box (which still weighed as much as the car at 2,796 pounds[4]). The greatest improvement to the DeLorean was the addition of spatial displacement, which allowed the car to travel not only through time, but through space.

Soon after, Doc built additional DeLoreans for use by the Institute of Future Technology.

In 1931B

The DeLorean time machine burned out after Edna burnt down Hill Valley.

One version of the DeLorean was stolen by Edna Strickland who took it back to 1876 to light Beauregard Tannen's half-finished saloon on fire, accidentally burning down Hill Valley and the DeLorean in the process. When Doc and Marty arrive at her residence in the newly created 1931B, the vehicle is a rusted hulk of metal on Edna's property.

Non-canon or disputable information ends here.

Behind the scenes

A rack of vacuum tubes and other components strapped to the hood replaces the time control microchip.

• In the animated series, the DeLorean is supposedly rebuilt, regardless of what Doc said about the dangers of time traveling.

• In the first script of Back to the Future the time machine was shaped like a refrigerator. The idea was scrapped, for fear of kids climbing into and becoming trapped in refrigerators. Because an abandoned refrigerator can become an inescapable trap for a small child, laws in most nations require that the door be removed when such an item is disposed of.

  • Coincidentally, the final version of the time machine was composed of stainless steel, from which many refrigerators are made of.

• At the end of Back to the Future, the alarm clock that the 1955 Doc had placed on the dashboard of the DeLorean could be seen. But in the beginning of Back to the Future Part II, it is no longer on the dashboard of the DeLorean.

• At the start of the 1990 behind-the-scenes TV show The Secrets of the Back to the Future Trilogy, host Kirk Cameron arrived in an Old West town in the DeLorean.

Construction of the DeLorean for the films

The base of the DeLorean's nuclear reactor was constructed from a hubcap of a Dodge Polara. The engine sounds came from a Porsche but the engine was never replaced with a Porsche engine and kept stock.[5] Aircraft parts and blinking lights were added for additional effects.

Since all American models of the actual DMC-12 had speedometers that only read up to 85 miles per hour, a modified instrument cluster was installed, with a speedometer that reached 95. (A law from the administration of President Jimmy Carter prescribed that automobile speedometers could not read more than 85 m.p.h. with the intent that if people could not read speeds higher than that, that they wouldn't drive faster than that.)

In popular culture

The Wolfram|Alpha computational knowledge engine defines a "delorean" as a unit of power equal to 1.21 jigowatts, and uses 88 miles per hour as a benchmark for comparing speeds. See: "speed cheetah".

In the game Borderlands there is an achievement on the Xbox 360 version entitled "1.21 Gigawatts" which is a clear reference to the amount of electricity needed for the time travel.

In the game Sonic CD (4th generation iPhone/iPod Only) there is an achievement called "88 miles per hour". Sonic's way of time traveling is similar to Back to the Future.

Similarly to Sonic CD, there is a trophy for the PS3 exclusive game Ratchet and Clank (Future): a Crack in Timecalled 88 MPH, though the action for doing so is by preventing a time travel rather than travelling through time.

In Grand Theft Auto V, there are several power stations which have the label "Danger: 1.21 GW", also referring to the amount of electricity needed.

The DeLorean Time Machine appears in Ready Player One as the vehicle of the protagonist Parzival in the OASIS. Parzival uses the DeLorean to win the race that is the first challenge and then speeds through the battlefield in the car during the final battle. The DeLorean is destroyed by MechaGodzilla during the final battle.

Great Scott …. Buckle Up !!!

DeLorean Time Machine - Ghostbusters Ecto 1 C - Knight Rider KITT

Buckle up, for a whirlwind adventure that throws Marty McFly's DeLorean Time Machine, the Ghostbusters' Ecto-1, and KITT from Knight Rider into a retrolicious time-traveling escapade !!!!

The year is 1985.... A temporal anomaly rips through the fabric of space-time, sending shockwaves across the fictional counties of Hill Valley, New York and LA.

In the idyllic town of Hill Valley, Marty McFly and Doc Brown are calibrating the flux capacitor of the DeLorean when a jolt of energy surges through the machine......
The time circuits spin wildly, throwing the DeLorean into a temporal vortex !

Meanwhile, in the bustling metropolis of New York, a PKE meter on the Ecto-1 flickers erratically.
Peter Venkman, Ray Stantz, Egon Spengler, and Winston Zeddemore are investigating a particularly stubborn haunting in an abandoned amusement park when the spectral readings go haywire. A blinding flash engulfs the Ecto-1, transporting it through time as well.

Across the country, KITT, the technologically advanced Trans Am, races down a deserted highway with Michael Knight behind the wheel.
Suddenly, KITT's internal systems blare a warning. An unidentified temporal distortion has been detected. Before Michael can react, KITT speeds into the anomaly, vanishing in a flash of light.

The three vehicles materialize in a swirling vortex of time energy, crashing onto a dusty road in the middle of nowhere. Marty, Doc, Peter, Ray, Egon, Winston, Michael, and KITT emerge from their respective rides, bewildered and confused.

As they assess the situation, a lone figure emerges from the shimmering heat haze.
It's Emmett Brown, Doc's eccentric inventor counterpart from an alternate 1985!
This Emmett, however, has never constructed a time machine. He explains that the anomaly is the result of a rogue experiment gone wrong, threatening to unravel the very fabric of time.

Our unlikely heroes, united by their unique vehicles and unwavering determination, join forces. Marty and Doc provide their expertise on the DeLorean's time travel tech.

Ray, Egon, and Peter utilize their ghostbusting equipment to scan for temporal anomalies.

Michael and KITT, with their advanced AI and arsenal of gadgets, assist in deciphering Emmett's scientific jargon.

Together, they embark on a thrilling quest through time, traversing different eras to locate the source of the anomaly.

Through hilarious mishaps, narrow escapes, and moments of genuine camaraderie, a bond forms between the unlikely crew.

Marty's youthful enthusiasm complements Michael's stoic resolve.

Doc's scientific ingenuity is matched by Egon's technical prowess.

Ray's optimism counterbalances Peter's cynicism, and Winston's dry humor keeps everyone grounded.

Even KITT, programmed for logic and efficiency, develops a grudging respect for the eccentric team.

As they inch closer to the source of the anomaly, they discover it's emanating from a hidden laboratory in the near future.

A rogue scientist, obsessed with manipulating time for personal gain, is conducting experiments that could tear apart the space-time continuum.

Using the combined firepower of the Ecto-1's proton packs, KITT's laser weaponry, and the DeLorean's time travel capabilities, they launch a full-scale assault on the laboratory.

The ensuing battle is a spectacle of 80's nostalgia, with proton beams clashing against laser blasts and the DeLorean weaving through a hail of gunfire.

In the end, it's a combination of Doc and Emmett's scientific know-how, Michael's strategic thinking, and the Ghostbusters' spectral expertise that disables the rogue scientist's machine.

The anomaly subsides, and the timestream stabilizes.

With the timeline secured, our heroes must part ways.

Doc and Marty use the DeLorean to return to their own 1985, forever bonded by their shared adventure.

The Ghostbusters pilot the Ecto-1 back to New York , ready to tackle whatever supernatural threats await them.

Michael and KITT speed off into the sunset, ready to uphold justice whenever duty calls.

The temporal anomaly may be a thing of the past, but the legend of their extraordinary team-up becomes an enduring echo throughout time, a reminder that with a little ingenuity, perseverance, and a whole lot of 80's flair.
