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.

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

#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.

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

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

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- l…….ook out !!!"

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 51955, 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.

History

Doc purchased the DeLorean DMC-12 from a seller named Robert, who had advertised it in the classifieds section of the August 111984 issue of the Hill Valley Telegraph.

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 41776 (the date the American declaration of Independence was signed) and December 250000 (the date of the birth of Christ) as examples, before inputting "a red-letter date in the history of science, November 51955". 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.

—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 212015, 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 11885[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.

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.

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.

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 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.

Time Paradox Explained - Back to the Future

Great Scott !!! We feature Doc Brown’s Time Travelling DeLorean in our Blog about one of the wonders of Time Travel the Time Paradox. What is a Time Paradox - How does it relate to Time Travel and we discuss the science involved.

Time Paradox

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

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

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

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.

Two Doc Browns

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.

Closed Loop Paradox

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

Travel through Time

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)

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

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

Bootstrap Paradox

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.

Time Paradox in Films

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

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

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

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?

Self Fulfulling Prophecy

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

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

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

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

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.

Black holes

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

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

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

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

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

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.

Screen Shot 2021-01-16 at 14.32.30.png

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.

Screen Shot 2021-01-16 at 14.34.56.png

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

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?

“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.”

And to leave you to ponder on the future in Doc Browns own words :

Check out our latest review for Sandstone Productions ' DeLorean Time Machine ' Hire ! Taking you Back to the Future !

David left us this review :

“What an amazing experience this was!

Chosen for our son’s 16th Birthday but due to pandemic ended up being an end of school celebration.

So easy to book, Mark knows his stuff and being a Back to the Future fan, the things we wanted he already had sorted.

Car is unbelievable, the level of detail is incredible, exactly like one in film.

Our son had an amazing drive around and did an incredible photoshoot around the town where we live.

So not only was it an end of school celebration to remember, he also has some fabulous photos to remind him.

Professional and friendly service and Mark only adds to the experience with his knowledge and interest of the film.

Would recommend for any celebrations but especially for Back to the Future fans”
