back to the future 2 time travel dates

The Entire Back To The Future Timeline Explained

The Back to the Future trilogy is a classic, with a weaving narrative that pinballs back and forth through time, folding in on itself over and over like a perplexing piece of origami. While these movies have been around for so long that the distant "future" they imagine is now our past, their storytelling is complex enough that it's understandable if you still don't fully understand how all the different timelines play out and relate to one another — which is why we're here to explain it.

There's really no good way to chronologically trace the timeline of the Back to the Future movies, since each one splits into alternates so many times that it would be confusing to attempt to look at them all side by side. Instead, what we're going to do here is follow the different timelines as they branch off, even though that requires some bouncing around through various decades and centuries. So buckle your seatbelts and hold on tight as we ramp up to 88 miles per hour and dive into all the time-traveling adventure of Back to the Future .

1885 - Original timeline

There's not a lot we know about the original version of 1885 before Marty and Doc started messing with it, but we do know one vitally important event that happens: Clara Clayton (Mary Steenburgen) was hired to be the new teacher at the Hill Valley school. She had just arrived at the Hill Valley train station, loaded up her wagon with her possessions, and was heading to her new home when a snake spooked her horses. She lost control of her wagon, and her horses took off galloping toward Shonash Ravine.

After careening into the ravine, Clara died without ever making it to her teaching post. Clayton Ravine wound up being named after her, and the story of her death became an urban legend at Hill Valley High. When students didn't like their teachers, they'd say they wished they would fall into the ravine like Clara Clayton. At the time of her death, Clara was single with no children.

1955 - Original timeline

In Hill Valley during the fall of 1955, a teenage George McFly (Crispin Glover) is up in a tree using a pair of binoculars to watch his high school crush Lorraine Baines (Lea Thompson) change in her bedroom when he falls out into the road and is hit by a car. The driver of the car turns out to be Lorraine's father, who — not realizing that George was peeping through his daughter's window — brings George into their house to recuperate.

Lorraine finds herself attracted to George, drawn in by his apparent helplessness, and the two decide to attend the Enchantment Under the Sea Dance together, where they kiss for the first time. However, Lorraine is also pursued by Biff Tannen (Thomas F. Wilson), another teen in their high school class who bullies George relentlessly. Although Lorraine chooses George, Biff remains fixated on her, and works to make George's life more miserable as a result.

On November 5, shortly before Lorraine and George meet, Dr. Emmett "Doc" Brown ( Christopher Lloyd ) slips off his toilet while hanging a clock, bangs his head, and is temporarily knocked unconscious. When he comes to, he's had a vision of an invention called a flux capacitor, which is what makes time travel possible. On November 12, the clock tower at the Hill Valley courthouse is struck by lightning.

1985 - Original timeline

The original Back to the Future film begins in 1985, where George and Lorraine are now married and live in a modest suburban home in Hill Valley. At work, George reports to Biff, who continues to bully him and creepily hit on Lorraine. Instead of doing his homework, George has now graduated to doing Biff's reports for him. Lorraine's brother Joey is in jail, and has failed to make his parole for at least the second time.

George and Lorraine have three children: Dave (Marc McClure), who is in his early 20s and works at Burger King ; Linda (Wendie Jo Sperber), who is around 19 and single, and their youngest, Marty (Michael J. Fox), who is 17 and dreams of being a rock star. Marty's best friend is the eccentric scientist Doc Brown, and he has a serious girlfriend named Jennifer (Claudia Wells), of whom Marty's mother doesn't approve.

After 30 years of refining his initial design, Doc finally perfects the flux capacitor and builds a time machine out of a DeLorean . Because his invention requires a huge amount of energy, he lies to a group of Libyan terrorists, promising that he'll build them a bomb with the stolen plutonium they supply and instead giving them a bomb casing filled with pinball machine parts. As Doc conducts the first test of his time machine at the Twin Pines mall, the terrorists arrive and shoot him dead. In an effort to escape from the terrorists, Marty jumps into the DeLorean and accidentally travels back in time.

1955 - Alternate timeline A

Arriving in 1955, Marty crashes into a pine tree and winds up in a barn. After hiding the time machine, Marty walks into town, where he sees a boy about to be hit by a car and rushes to push him out of the way. The car hits Marty instead, and the driver brings him inside, after which Marty realizes that the boy he saved was his father, and that instead of becoming attracted to George during his convalescence, Lorraine is now attracted to Marty, who goes by the alias Calvin Klein.

Determined to restore the timeline, Marty seeks out the advice of the 1955 version of Doc, who has just had his vision of the flux capacitor. Doc instructs him to do whatever he has to do in order to get his parents together before Marty's timeline is completely erased from existence. In the process, Marty's intervention gives George the idea for a sci-fi novel. Marty's plan to push his parents together results in George standing up to Biff for the first time, and a newly confident George finally kisses Lorraine.

Meanwhile, Marty gives Chuck Berry the idea to write the song "Johnny B. Goode," three years before the song was composed in the original timeline. Marty and Doc take advantage of the clock tower lightning strike to create the power needed to run the flux capacitor, harnessing the lightning so Marty can return to 1985. Before Marty departs, he writes Doc a letter warning him of his death in 1985, but Doc rips the letter up, saying that the consequences of knowing his own future could be disastrous.

1985 - Alternate timeline A

Marty decides to set the time of his return to a few minutes earlier than he left, hoping he'll be able to save Doc. However, by the time he arrives at the mall — now Lone Pine Mall, thanks to the tree Marty crashed into in 1955 — he's too late, and watches Doc get shot again. However, after the terrorists depart and Marty approaches Doc's body, Doc sits up, revealing that he's wearing a bulletproof vest. Stunned, Marty asked how he knew; Doc admits that he let curiosity get the best of him, and taped Marty's letter back together.

Marty returns home to find his family significantly better off than he left them. George is now a published science fiction novelist, and he and Lorraine are healthier and much more flirtatious than they were in the original timeline. While they still live in the same house, the decor has received an upgrade, although Marty's room remains the same. Biff now owns an auto shop, and is responsible for the detailing on the McFly cars.

Instead of a Burger King, Dave now works in an office, and while we still don't know much about Linda's life, she's at least dating a lot, which seems to speak to her increased self-confidence. Perhaps thanks to her own altered high school dating experience, Lorraine now loves Jennifer, and the McFlys have purchased Marty a black pickup truck, which they expect him to take on his weekend trip with her.

2015 - Alternate timeline B

We never see what would've originally happened in the original 2015 timeline before Marty traveled back to 1955 the first time, and we actually never get to learn exactly how things play out in the first new timeline he creates either. The first perspective of 2015 that we get is Doc's, whose presence in 2015 causes yet another timeline to branch off. However, odds are that most of this new timeline was very similar.

In this timeline, after graduating high school, Marty going to pursue a career in music, but finds his rock star dreams thwarted due to a hand injury sustained during a car accident. Eventually, Marty and Jennifer get married in the Chapel O' Love and have two children, Marlene and Marty Junior. In 2015, Marty Jr. agrees to help Biff's grandson, Griff Tannen, rob the Hill Valley Payroll Substation. He's apprehended by police, and sentenced to 15 years in prison. Marlene then attempts to break him out, and she is sentenced to 20 years.

Doc witnesses all of this during his visit, and takes a newspaper to help him track alterations to the timeline. He also gets a hover conversion for the DeLorean which allows the car to fly, replaces the DeLorean's energy source with a Mr. Fusion portable nuclear reactor, and puts his dog, Einstein, into a suspended animation kennel — which honestly seems pretty risky, considering that he's about to reset the whole timeline again.

2015 - Alternate timeline C

Just as everything seems perfect for Marty in 1985, Doc returns from 2015 and informs Marty and Jennifer (now played by Elizabeth Shue) that their future children need their help. The three of them pile into the DeLorean — which can now fly, thanks to its alterations — and zip back to 2015, thus spinning off a third alternate timeline. Biff sees them disappear, but can't make sense of what he saw for another 30 years.

In 2015, Jennifer is knocked unconscious while Marty impersonates his son so he can avoid the payroll robbery, thus giving both of his children a better fate. Thanks to Marty's intervention, Griff and his gang are arrested instead. Feeling lucky, Marty purchases a Grays Sports Almanac, detailing the results of sporting events from 1950-2000, but Doc makes him throw it away. However, recognizing the flying DeLorean from 1985, a much older Biff realizes that it's a time machine. Unbeknownst to Marty, Old Biff grabs the sports almanac and steals the DeLorean.

Meanwhile, Jennifer is brought to her future home by well-meaning police officers who believe she's the 2015 version of herself. While hiding from her future family, she witnesses the older Marty being fired by his boss after agreeing to participate in an illegal scheme with a coworker. Afterward, she reconnects with Marty and Doc, and the trio (plus Einstein, who's thankfully fine) return to 1985.

1955 - Alternate timeline D

Old Biff returns to November 5, 1955, the same day Marty originally traveled to in the first movie. He tracks down the teenage Biff at his grandmother's house and gives the Grays Sports Almanac to his younger self, instructing him to use it to place bets on sporting events. At first, the younger Biff is skeptical, but Old Biff convinces him of the almanac's authenticity by using it to predict the results of a live event being reported on the radio.

After convincing teenage Biff of the almanac's potential power, Old Biff instructs him to always keep it hidden and locked up. He also warns his younger self that at some point in the future, a "kid" or a "crazy, wild-eyed old man who claims to be a scientist" may show up asking about the book. When that happens, Old Biff tells Young Biff that he shouldn't hesitate to kill them. Old Biff then takes the DeLorean and returns to 2015, leaving the almanac with his younger self. Not long after, Biff uses the sports almanac to place his first bet, and quickly starts amassing a fortune.

1985 - Alternate timeline D

Sometime after Marty was born, Biff — now a billionaire, thanks to the almanac — murders George McFly and marries Lorraine. He also starts a company called BiffCo, uses his vast resources and influence to legalize gambling in California, and builds himself a 27-story casino in Hill Valley named Biff's Pleasure Paradise. Biff's control doesn't end with his businesses, though. He also largely usurps control of the Hill Valley Police Department, leading to Hill Valley becoming a teeming crime hub. As for Lorraine's children, by 1985, Dave has fallen into a life of crime, although Biff pays to keep him out of jail; Linda lives off of Biff's credit cards; and Marty is sent to boarding school in Switzerland. Back in Hill Valley, Biff forces Lorraine to get cosmetic surgery and she becomes an alcoholic.

This is the 1985 that Marty and Doc return to, in which they quickly realize that something in the past has gone horribly wrong. Doc learns that the 1985-D version of himself has been committed to a mental hospital, and that George McFly is dead. Marty confronts Biff, who readily admits everything about the almanac and his murder of George, and also tells him exactly when he received the almanac from his future self. Biff then attempts to shoot Marty with the same gun that killed his father, but Marty and Doc escape in the DeLorean.

1955 - Alternate timeline E

Marty and Doc travel back to 1955 to steal the sports almanac back from younger Biff and restore the timeline. Most events play out as they did in 1955-A, since Doc and Marty have to be careful not to allow the other versions of themselves from the first movie know they are there. Marty manages to steal the almanac from Biff after George knocks him unconscious, but Biff later manages to steal it back.

Finally, Marty is able to retrieve the almanac from Biff's car while he's driving it, resulting in yet another car crash. Doc implores Marty to burn the almanac, which he does using a matchbook he'd taken from Biff's Pleasure Paradise in 1985-D. As the almanac burns, the logo on the matchbook changes into the one for Biff's auto detailing business from 1985-A. Satisfied that they've restored the timeline, Marty and Doc prepare to return to 1985, but before Doc can land the DeLorean and allow Marty to climb in, the flying car is struck by lightning and disappears.

1885 - Alternate timeline F

Doc arrives in 1885, back in the earliest days of Hill Valley, and finds that the time circuits of the DeLorean have been completely fried by the lightning strike. Lacking the technology to fix the time machine, Doc realizes he's stranded in 1885, and builds a new life for himself as a blacksmith. After spending some time in 1885, Doc decides to hide the DeLorean in a mine shaft and leave detailed instructions for Marty on how to fix it in 1955, so he can return to 1985. Doc turns the letter over to the postal service, instructing them on the exact location, date, and time that they'll be able to deliver it to Marty in 1955. In his letter, he gives Marty explicit instructions not to return for him.

One of Doc's jobs as a blacksmith is shoeing a horse for Buford "Mad Dog" Tannen, Biff's ancestor, but Tannen then refuses to pay. Afterward, the horse throws Tannen off, causing him to break a $5 bottle of whiskey. Tannen blames Doc for the incident, saying he owes him $5 for the whiskey and $75 for the horse.

Shortly thereafter, Doc is asked by the mayor to go meet the new schoolteacher at the train station, leading him to save Clara Clayton from her fall into the ravine. The two quickly fall in love, but their romance is sadly short-lived. After getting his portrait taken in front of the new courthouse clock, Doc is shot in the back by Tannen while dancing with Clara at the town festival. He dies and is buried in Hill Valley, where his grave is later discovered by Marty in 1955 after receiving Doc's letter.

1885 - Alternate timeline G

After enlisting the help of the 1955-F Doc to fix the recovered century-old time machine, Marty travels back to 1885, despite Doc's instructions. However, Marty nicks the fuel line once he arrives in 1885, causing the DeLorean to run out of gas. Although Doc challenges Marty's decision to return for him, Marty explains that Doc has only days left to live. Doc and Marty — the latter of whom is now using the alias "Clint Eastwood" — begin working together to try to figure out a way to get the DeLorean up to the required 88 miles per hour without fuel.

Aside from Doc and Marty's attempts to get the time machine working, most events play out as they did in 1885-F, up until the town festival, when Marty saves Doc's life. Angry at Marty's interference, Mad Dog Tannen challenges him to a duel in two days' time. Marty and Doc realize that they have to execute their plan to travel back to the future before then, and start preparing to hijack a train. However, Doc becomes so despondent after saying goodbye to Clara that he refuses to leave.

The following morning, a heartbroken Clara buys a one-way train ticket out of Hill Valley, while Marty is forced to face Tannen after all. Using a trick from an old Clint Eastwood Western, Marty manages to survive and incapacitate Tannen, and he and Doc go to commandeer the train, not realizing that Clara is on board. As the train approaches 88 miles per hour, Doc chooses to save Clara rather than return to the future with Marty, and as the train soars off the track into the ravine, the DeLorean travels through time again.

1985 - Alternate timeline G

Marty returns home for good, to a timeline very much like the one he'd hoped to restore, with the exception that the ravine is now named "Eastwood Ravine," after he supposedly perished in it in 1885-G. No sooner has Marty arrived back in 1985 than a modern train comes through, smashing the DeLorean to bits while Marty jumps to safety. Although it's bittersweet, Marty realizes that this is what Doc wanted: to have the time traveling be over, the timeline secured, Marty back home, and Doc with his true love.

Marty reunites with Jennifer, and the two of them go for a drive. They're challenged to a race by Marty's future criminal accomplice at a stoplight, but instead of racing, Marty puts his truck in reverse. Watching a Rolls Royce cut into the would-be path of his truck, Marty realizes he would have gotten into a devastating car accident, which Jennifer realizes is the accident that would've cost him his music career. Looking at the fax from 2015-C in which Marty was fired, Jennifer sees that it's been erased.

Marty and Jennifer head back to the site of the wrecked DeLorean, and are shocked when a flying locomotive engine appears out of nowhere. It turns out that sometime after Marty traveled back to the future, Doc stole another train and built a new time machine, which he and Clara are using to travel throughout time. Doc reveals that he and Clara are now married with two young sons, Jules and Verne, after their favorite science fiction author. Doc urges Marty and Jennifer to make the best futures possible, since nothing has yet been written, and then takes off in his train for worlds — and times — unknown.

This is the extended timeline of the events of the Back to the Future universe, including the animated series , the comics , Back to the Future: The Game , Back to the Future: The Card Game and Doc Brown Saves the World .

These sources combined have provided a detailed explanation for how time travel works in the Back to the Future universe:

Every time someone travels back in time, a new timeline is created that branches off from the last timeline. [1] This creates a ripple effect in the time stream. [2] Any major changes that would effect the life of the time traveler are slowed, as the time traveler is temporarily protected by a time bubble . [3] Traveling behind these changes slows the deterioration of the time bubble, [4] whereas traveling past these changes accelerates it. [5]

The ripple travels backward through time as well as forward, allowing the time traveler to see their own future, [6] before the time ripple catches up to them and the bubble protecting them pops. [7]

Once the time bubble pops, the timelines merge and the time traveler's counterpart from the alternate timeline merges as well, with the new timeline reflecting the time traveler's counterpart's actions in the past, but continuing from the actions of the time traveler in the present and future. [8] The exception to this is when the time traveler creates a timeline where they no longer exist. Once the time bubble pops in that scenario, the time traveler completely fades from existence. [9]

Each jump back in time creates a new timeline. Note that each timeline includes everything in the previous timelines except where deviations occur.

He sent it to the beginning of August, when he knew he and his dog were safe in the fireproof lab in his garage.

Timeline 2 [ ]

• The 465.3 megawatt capacity of the power grid would be converted to flux capacitance energy , which would send the time traveler to the date set on the time circuits displayed on a meter inside the chamber door. The limitations of using less than half of the energy needed to properly power the chamber meant that there was only four hours of flux energy available before the time bubble protecting the time traveler would burst. This would cause the time traveler to fade from existence in the past and re-appear back in the chamber in the present

This timeline was created when Stanford S. Strickland traveled from 1983 to 1946. ( Back to the Future: Biff to the Future )

• Mr. Strickland arrived from 1983. He walked to the school, and witnessed Biff picking on a smaller child. George McFly stuck up for the child, and Biff punched George, causing his nose to bleed. Lorraine Baines informed a senior teacher, Miss Hodges , about the bullying, just as the younger Strickland apprehended Biff, after calling him a slacker .
• The elder Strickland tried to stop Miss Hodges from intervening, but he was surprised to find out that she was the one who wanted to ship Biff to Idaho, and his younger self stopped her as he believed that Biff could become a good student with the proper guidance.
• The elder Strickland couldn't do anything else to change things, as he was accused of being a " sex herbert " by the young Biff, and Miss Hodges thought that might be true, as he did touch her when he tried to stop her from interfering.
• Devastated that he had changed his own memory as he didn't want to admit to himself that he was the reason why Biff remained in Hill Valley, Strickland walked to an alley, so he wouldn't be seen disappearing by any bystanders, and sat in a crouched position with his head in his lap until time ran out.
• Sunday, May 1 : Mr. Strickland is returned to 1983, still in a defeated position, and doesn't respond to anyone.
• The civic committee met again, commenting that no one had been able to reach Strickland since the incident, and he hadn't reported in to the school either (it's unknown which school he was working for, as Hill Valley High School burned down in 1979 and wasn't rebuilt until at least some point after 1985 ). He blamed himself for everything and didn't want to interact with anyone.
• The committee decided that the best attempt to stop Biff would be to prevent him from being born, by stopping the wedding of his parents. The only problem was that no records were available before 1950 , since everything was lost after Biff bulldozed the Hill Valley Courthouse to build his casino and hotel . Goldie Wilson realized that they would be able to determine the date by going to the Biff Tannen Museum inside Biff's casino.
• Upon arriving at the museum, Doc Brown was required to buy a cigarette and hold it in his hand, due to the museum's " smoking required" policy. He was already disgusted by the museum, but he pressed himself to go on. He learned that Biff's parents, Myra Benson and Kid Tannen (going by Thomas Tannen after escaping from prison), married at the Hill Valley Church of the Heather on December 6 , 1936 .
• Doc went back to the committee, and they developed a plan. Doc would arrive at the wedding, and object to the marriage, stating that the bride is already married to his son "Melvin", and that he thinks that she is pregnant. The committee then travels once again to the power grid, where the chamber is hooked up. Doc enters the chamber, disappearing into the past, and the city's power goes out again. This time Biff demands his gang to stop whoever is causing the blackouts. The Hill Valley Civic committee can't disconnect the wires from the power grid, and are apprehended by the police.

Timeline 8 [ ]

This timeline was created when Doc traveled from 1983 to 1936. ( Back to the Future: Biff to the Future )

• Date unknown : Biff Tannen is born.
• Doc arrives from 1983, and takes a taxi to the church. He is about to object to the wedding, when he hears a baby crying. When the babysitter calls him Biff, Doc realizes he made a mistake. Myra had become pregnant earlier that year. Kid wanted her to have an abortion, but she wouldn't do it, as it was illegal, and she felt that her mother would kill her if she did.
• Kid and Myra married simply for the purpose of making it seem like Biff wasn't born out of wedlock. The two parted ways immediately after the wedding, and neither parent wanted Biff. Because of this, Kid's mother, Gertrude Tannen , took custody of him. Before he left his son, Kid gave Gertrude a forged birth certificate that stated that Biff was born the next month, January 1937 .
• Doc planned to come up with a "Plan C" once he arrived in 1983, and disappeared into the future as he was looking at his pocketwatch .

The Hill Valley Telegraph reports that Doc has been committed to a mental ward.

• Date unknown : Biff stepped out of the chamber and realized he was in BiffCo, as the chamber was brought there after the police apprehended the members of the Hill Valley Civic Committee. Biff wanted to know what the refrigerator did, and why it took so much power. Doc refused, and Biff told him that there were ways to get him to talk if he wouldn't talk willingly.
• Sunday, May 22 : Doc Brown is committed to Mental Ward B at the Hill Valley Hospital after being declared legally insane. Richard Nixon announces he will run for a fifth term in office and promises to end the Vietnam War by 1985 . BiffCo's representatives announce that the company is going to build a new dioxin plant in Hill Valley and takes over Lone Pine Mall . [57]
• Date unknown : Marty McFly leaves his Switzerland boarding school to tour with a band. They played in Switzerland, Austria, and Venice. [58]
• Doc appears catatonic, leaving Biff mystified, as he is unable to get Doc to respond.
• Doc is moved to the Hill Valley Asylum .
• Biff enlists the help of a German psychiatrist, to determine what is wrong with Doc Brown.
• Biff announces his run for President of the United States , as Richard Nixon had decided not to run for a sixth term in 1988 .
• 3-D lets Biff know that the German psychiatrist that Biff hired visited Emmett Brown and in the Hill Valley Insane Asylum and let him know that he has news about his condition. Biff learns that Doc Brown used a practice performed by certain Eastern religions to shut of certain higher functions of his brain, which put him in a state similar to patients that had been lobotomized . Biff has Skinhead track down Doc's dog, Einstein , to attempt to bring him out of his mental state.
• Lorraine Baines McFly didn't want Biff to ruin the United States as he did to Hill Valley and her family, so she shoots him in the chest. However, she fails as the bullet is stopped by the book that contains the record of people that he had paid off.
• Tuesday, March 3 - Biff brings Marty , Dave and Linda back to Hill Valley so that he can have the image of a family man during his presidential run.
• April : Biff discovers that Doc Brown had built a time travel chamber .
• May : Biff discovers that Marty McFly visited Doc at the asylum after Marty had received the letters that Doc wrote in hopes of getting him to become his assistant to make his time travel back to 1955 a reality.
• Biff blackmails Doc into using the time machine, saying he'd kill Marty if he didn't, just as he did years later. He tells Doc to send him to 1996 so he can pick up ten years worth of almanacs and business books so he can play the stock market, which he could use to show the American public that he is a savvy businessman.
• Instead, Doc uses a remote control override to send him back to March 18 , 1884 instead.

Timeline 9 [ ]

This timeline was created when Biff traveled from 1986 to 1884. ( Back to the Future: Biff to the Future )

• Tuesday, March 18 : Biff arrives from 1986. He tells his grandfather, Buford Tannen, that he wanted to take a "shot" of him, meaning that he wanted to take his picture. Thinking he meant to kill him, Buford shoots him with his pistol.
• Four hours after he left, Biff reappears with a bullet hole in his head, as he was shot dead by his own great-grandfather  in 1884.
• Doc activates his electrified conducting mat , which electrocutes Biff's gang , preventing them from killing anybody.
• Saturday, May 31 : Biff is declared dead by a power surge, and Lorraine is set to inherit his fortune.
• Biff Tannen is buried, and his funeral has a large turnout, as the residents of Hill Valley wanted to make sure he was really dead.
• Lorraine, Dave, Linda, and Marty McFly, along with Goldie Wilson and Doc Brown announce that Biff's businesses would be closed and that they would work together to make Hill Valley once again a nice place to live.

21st century [ ]

• Tiffany Tannen , Biff's daughter, worked for CusCo . [59]
• Electra McFly is born.
• Electra McFly works for CusCo. [60]
• Biff Tannen returnes with the DeLorean. He is slowly being erased from history, as his new past had caused him to no longer be alive in 2015. While he was in pain from the ripple effect catching up to him, he broke his cane off in the DeLorean and left the Blast from the Past bag behind.
• Doc, Marty, Jennifer and Einstein travels in the DeLorean from 2015 to 1985, not realizing that the past had been changed.
• Date unknown : Fired Up , the greatest hits album by Marty McFly and The Pinheads tops the charts and goes platinum. [61]

Timeline 10 [ ]

This timeline occurs when Doc, Marty, Jennifer, and Einstein travel from 2015 to 1985. ( Back to the Future Part II )

• At 9:00 PM, Marty lies his sleeping girlfriend down on the porch swing outside of what he believes is her house, however he is surprised to see bars on the windows.
• Shortly afterward, Marty arrives at what he believes is his house, however the gate is locked. He jumps over it and opens the window to what he thinks is his bedroom. However, an African-American family now lives in the house, and he lands on the bed of a teenage girl named Loretta . Her father comes into the room and chases Marty out of the house with a wooden baseball bat .
• Marty discovers the date on the Hill Valley Newspaper on Principal Strickland's porch. He discovers that Hill Valley High School burned down years ago, and Strickland now weilds a shotgun to defend himself from armed teenaged gangs .
• Upon arriving at Biff Tannen's Pleasure Paradise Casino & Hotel, Marty is knocked out by Biff's gang, and is taken to the penthouse suite. He discovers that his mother is married to Biff, his sister had maxed out the limits on her credit cards, his brother is in jail, and his father was murdered in 1973.
• Doc goes to the closed Hill Valley Public Library and searches for clues that will explain the timeline he has found himself in. He discovers that his counterpart in this timeline has been declared legally insane and has been committed.
• Doc goes to the County Asylum, where his counterpart is now being held, and bribes the Asylum nurse to let him into his counterpart's room, giving his birth name of Von Braun as his surname. He is shocked to discover that his counterpart can not answer any of his questions. He assumes he had been lobotomized , not knowing that his counterpart had turned off certain higher brain functions to protect himself.
• Doc meets up with Marty at Oak Park Cemetery and then they travel to what remains of Doc's lab. He explains that Biff stole the sports almanac, by magnifying a photograph where Biff had the book in his pocket. He tells Marty that they need to find out when Biff gave his younger counterpart the book, as traveling to the future at that point would only result in traveling to the future in that timeline.
• Marty decided that the only way to find out is to ask Biff, and he heads back to Biff's casino hotel.
• While Marty is talking to Biff, Doc purchases Archer Space Patrol walkie talkies .
• Marty let Biff know that he knows about the almanac, and Biff tells him that he was given the book by an old man on November 12, 1955. He also states the old man told him that a kid or a wild haired old man who claimed to be a scientist would show up one day. Biff then fired a gun at Marty, but he caused Biff to miss by shooting an ashtray at him.
• Biff chased Marty up to the roof, and let him know that he killed his father with the same gun. Marty jumped off the roof, and Biff gloated. He walked to the edge to take a look down at the street and was surprised as Marty rose back up. He was then knocked out when Doc opened up the gull-wing doors of the DeLorean.
• Marty gives Doc the date, and Doc states that either that date is a significant date in the fabric of time, or it could just be a coincidence. Marty and Doc travel from 1985 back to 1955.

Timeline 11 [ ]

This timeline occurs when Doc and Marty travel from 1985 to 1955. ( Back to the Future Part II )

• 6:00 a.m. Doc and Marty arrive from 1985 in a DeLorean technologically improved than the one (with depleted plutonium) in which the younger Marty has already arrived. They have left Einstein at Doc's garage and Jennifer Parker safely asleep at home in 1985, as Doc surmises that they will not be erased by any changes to the future that they will make. He also advises Marty that Biff’s initial acquisition of the almanac must not be interfered with, so that the elderly Biff will return the time machine to 2015 thinking he’s succeeded.
• Later that same morning. The elderly Biff arrives from 2015 (in yet another instance of the DeLorean) with the almanac. He then locates his younger self later that day at Western Auto, picking up his car - and having an argument with Terry over the $302.57 repair bill. As this goes on, Marty smuggles himself into the back seat of Biff's car.
• Accompanied by Babs, Lorraine has just picked up her outfit for the dance from Ruth's Frock Shop. As young Biff boasts to her that he will marry her someday, she rebuffs his advances. Biff is then about to jump into his car to drive home and get ready for the evening, when he encounters an elderly stranger occupying the driver’s seat. Although the stranger is mysteriously able to start the car, Biff apparently fails to recognize him as his older self, who then informs him that "Today’s your lucky day."
• Marty, hiding in the back seat of the car, is an intimate witness to the elderly Biff’s demonstration of the power of the almanac, but he does not interfere, as Doc has advised. The young Biff tells his older self he’ll "...take a look at it."
• 6:38 p.m. : Thinking he’s done enough to change the future, and intending to escape detection, the elderly Biff departs in the DeLorean to the same moment he departed in 2015.
• 9:28 p.m. Marty retrieves the Sports Almanac from an unconscious Biff, while Doc departs the Lyon Estates construction site to fly towards the roof of Hill Valley High School.
• A more mature and fore-knowledgeable Marty fights off Match, Skinhead and 3-D and keeps them from jumping the naive Marty, allowing the events of that timeline to occur as they had before (i.e., as Marty recalls it from his point of view). Marty avoids any direct contact with his day younger self, until he loses the almanac to Biff again.
• After much wasted time and effort, Marty ultimately retrieves the almanac from Biff’s car. Biff, who has not paid for the $300 repairs after his first wreck, crashes his '46 Ford a second time, an event that had not happened in any previous timeline. Burning the almanac causes this timeline to fade back, making Old Biff's visit to the past mostly inconsequential, except for Biff's extra encounters with Marty. Marty and Doc are able to visually confirm the erasure of the alternate 1985 from items they’ve retrieved from that alternate future.
• 9:44 p.m. The hover-converted DeLorean from 2015, with Doc on board, gets unexpectedly struck by lightning just outside Lyon Estates and sent seventy years back in time to January 1 , 1885 due to an on-board malfunction Doc neglected to correct. [62] The overload of the time circuits also causes the DeLorean to be temporal duplicated . The temporal duplicate DeLorean is simultaneously sent seventy years into the future, without Doc, to 2025 . [63]

Timeline 12 [ ]

This timeline occurs when Doc travels from 1955 to 1885. ( Back to the Future Part III )

• 12:00 a.m. Dr. Emmett Brown accidentally arrives from 1955. The DeLorean's time circuits have been scrambled and shorted out by an overload caused by the lightning bolt, rendering the car useless for time travel and stranding Doc in the past. The overload also permanently damages the car's flying circuits, disabling its hover-conversion feature for good.
• Stranded in 1885, Doc settles in Hill Valley, where he sets himself up as a blacksmith. He then tries improvising methods in attempting repairs on the DeLorean, only to realize that most of the technology he needs will not be available until the next century (i.e. suitable replacement parts for the time circuits yet to be invented around 1947 at the earliest.) Nevertheless, Doc becomes adept at shoeing horses and repairing wagons, alongside his own experiments using the primitive technology available for the time.
• With the DeLorean's time circuit control microchip shorted out by the lightning bolt, Doc writes detailed instructions (including drawing schematic diagrams) on rebuilding it with 1955-era vacuum tubes and transistors (in a sense, Doc teaches his younger self how to repair the time machine.) He then places these in the DeLorean before burying it in the Delgado Mine , where he hopes it will remain undisturbed and preserved until his younger self and Marty unearth it 70 years hence.
• Blacksmith Emmett Brown is hired by Buford Tannen to shoe Buford's horse, but is not paid. After getting thrown off his horse and breaking a bottle of whiskey , Buford blames Doc for the accident and demands a total of eighty dollars from him; five dollars for the whiskey and seventy-five dollars for the horse, which was shot.
• Saturday, July 4 : Doc passes out after drinking one shot of whiskey at the 4th of July celebrations.
• Saturday, August 29 : There is a meeting of the townspeople over who will pick up the new schoolteacher on September 4 . Doc volunteers.
• Tuesday, September 1 : Having lived in 1885 for 8 months, [33] Doc writes a letter to be delivered personally by Western Union to Marty McFly on November 12 , 1955 exactly at 9:45 p.m. to the exact stretch of road he was hovering above when he was struck by lightning.
• Friday, September 4 : A train pulls into Hill Valley Station, carrying the new clock for the courthouse - and Clara Clayton aboard as a passenger. Doc meets her at the platform and brings her to the schoolhouse, where the two fall in love. Unknowingly, Doc also prevents Clara's death that day, and Shonash Ravine is never renamed Clayton Ravine in her memory.
• Saturday, September 5 : The Hill Valley Festival . A photographer takes a portrait of Doc posing next to the new courthouse clock (this photo is discovered by Marty and young Doc in 1955 at the library). While Doc dances with Clara, Buford Tannen shoots Doc in the back because he never paid Buford the eighty dollars.
• Monday, September 7 : Doc dies of the bullet wound Tannen caused, and is buried in Boot Hill Cemetery - which is fittingly adjacent to Delgado Mine, where the DeLorean (with repair instructions) is safely buried. Clara, grief-stricken over the loss of her man, erects a headstone on his grave in eternal memory of him.
• 9:45 p.m. A vehicle driven by a Western Union agent arrives at the entrance to Lyon Estates. The agent delivers to Marty, on time at that specified location, in the pouring rain, the letter Doc dispatched in 1885.
• 10:05 p.m. Lightning having just struck the clocktower, Marty scares the young Doc by "returning" on foot seconds after Doc sent the younger Marty back to the future, in effect creating an unexpected closed loop (from the young Doc’s point of view). Doc utters "Great Scott!" and suddenly faints. Marty drives the unconscious Doc back to his house in Doc's car.
• 7:01 a.m. : Young Doc reads the soggy old letter his 30-year-older self wrote seventy years in the past.
• Marty insists on going back to 1885 to rescue his friend.
• Tuesday, November 15 : Doc repairs and "soups up" the unearthed DeLorean, building a new time circuit with vacuum tubes and transistors. He also fits the DeLorean with new whitewall tires , and installs fresh oversized batteries on his and Marty's walkie talkies.
• 10:00 a.m. Marty leaves 1955 and heads back to 1885 to rescue Doc.

Timeline 13 [ ]

This timeline occurs when Marty travels from 1955 to 1885. ( Back to the Future Part III , the framing stories in Back to the Future: Untold Tales and Alternate Timelines , and the flashback scenes in Back to the Future: Continuum Conundrum )

• 8:00 a.m. Marty McFly arrives in 1885 to rescue Doc from impending doom. Native American Horseback-archers , who were on the run of the Federal Forces, shoot the DeLorean's fuel line, damaging it and leaving the car with no fuel at all. After hiding the DeLorean in a bear's cave, Marty later meets his ancestors Seamus , Maggie , and William McFly on the McFly farm and assumes the name " Clint Eastwood ".
• Marty arrives in Hill Valley, and upsets Buford "Mad Dog" Tannen, great grandfather of Biff Tannen , at the Palace Saloon, causing Tannen to nearly hang Marty. Doc saves Marty in time. Marty informs Doc of his impending death involving Buford and his infatuation with Clara Clayton . Aware that he will fall in love with Clara and worried about changing his future, Doc decides not to pick her up, as he has already volunteered to do five days ago. He and Marty then decide to leave 1885 and go back to 1985, but Marty notes about the DeLorean's damaged fuel line, realizing that there's no way to get the car up to 88 mph without gasoline, which will not be available until next century.
• With 6 horses, Doc and Marty ride out to the cave where Marty hid the DeLorean. They attempt to get it to up 88 mph on the way back to Hill Valley, but this proved unsuccessful as Doc explains that even the fastest horses in the world can reach nowhere near that speed.
• Doc tries using whiskey as fuel for the DeLorean's engine, but this only blows the fuel injection manifold, rendering the car completely powerless. He and Marty then think of various alternative methods to get the DeLorean up to 88 mph, but none of them seem practical.
• A train pulls into Hill Valley Station, carrying the new clock for the courthouse - and Clara aboard as a passenger. This gives Doc and Marty the idea of borrowing the locomotive to push the DeLorean. (They fail to recognize Clara standing behind them at the platform, waiting to be picked up. With no one to meet her, she then rents two horses and a wagon from Joe Statler, then sets out to find the schoolhouse on her own.)
• Doc and Marty ride out to Carson Spur, near the incomplete Shonash Ravine Bridge, ultimately deciding it is the perfect stretch of level track on which to push the DeLorean up to 88 mph with the locomotive just before they reach the edge of the ravine (over which the completed bridge would then exist upon arriving back in 1985).
• As Doc and Marty survey the bridge (which is scheduled for completion the following year), Clara's wagon runs away after a snake spooks the horses pulling it. Doc then comes to her rescue, saving her life. It is love at first sight. Much to Marty's horror, he and Doc realize that they unknowingly altered future history, resulting in Shonash Ravine not being re-named in memory of Clara. Marty nevertheless insists on getting the DeLorean ready to get them back to the future.
• After fitting the DeLorean with flanged steel railroad wheels, Doc uses a makeshift model railroad to demonstrate to Marty the plan on getting them back to the future. Immediately after, Clara arrives, asking Doc to repair her telescope, which had been damaged when it fell off the wagon during the rescue the day before. Doc, agreeing to perform the repair job without charge, becomes even more smitten with her.
• Evening. The Hill Valley Festival . Doc and Marty have a photograph taken, posing next to the new courthouse clock (this photo is given to Marty in 1985 by Doc at the spot where the DeLorean was destroyed by a locomotive near Eastwood Ravine). Later on, while Doc and Clara dance, Buford Tannen arrives and attempts to shoot Doc, but Marty interferes and saves him. Buford, angered by Marty's action, calls him " yellow ", challenging him to a duel on Monday morning. Aiming to prove himself to Buford that he isn't "yellow", Marty agrees to the face-off, setting it for 8 a.m. that morning.
• 7:00 a.m. Marty wakes up. After being confronted by Doc about the dangers of fighting Buford, Marty checks his photograph of the tombstone from 1955, and gets a shock. The future in which Doc is killed is replaced by one in which Marty, aka "Clint Eastwood", is likely to be killed.
• Evening. Doc and Marty haul the DeLorean out to Carson Spur, where they unload the car onto the tracks in preparation for their trip back to the future. Later that night, while an exhausted Marty sleeps, Doc tells Clara the truth and says goodbye to her, but she doesn't believe him. Both are broken-hearted: Doc heads back to town and gets a drink at the Palace Saloon, while Clara prepares to leave Hill Valley.
• Buford and his gang rob the Pine City stage.
• 8:00 a.m. Marty has a showdown scheduled with Buford Tannen outside Palace Saloon. Marty and Doc escape through the saloon's back door when Buford spots Marty, and again calls him "yellow". Marty still decides not to face Buford, showing an incredible amount of growth from a mere day earlier, and is about to walk away when Buford and his gang get a hold of Doc and threaten to shoot him.
• A train pulled by Locomotive 131 pulls into Hill Valley Station. Clara, deeply upset over losing Doc, then boards it before it departs for San Francisco.
• Marty decides to face Buford, who then shoots Marty in the chest. Using a trick learned from the Clint Eastwood movie A Fistful of Dollars (which was being watched by Biff in 1985), Marty survives, much to Buford's surprise. Marty then throws several punches at Buford, finally knocking him face-first into a manure cart, to the delight of the townspeople.
• Buford and his gang are arrested for the robbery of the Pine City stage.
• Taking one last look at the photo of the tombstone, Marty and Doc are relieved as it disappears (after having been damaged from Marty's punch-out with Buford). The future in which Marty is killed is replaced by one in which both Doc and Marty survive. They then head off to the railroad line to follow the train that had just departed.
• Meanwhile, on board the train, Clara overhears a passenger talking about the heartsick Doc; her belief restored, she stops the train and jumps off to find him. She discovers clues at the blacksmith shop and rides on horseback towards Carson Spur . She must reach Doc before he vanishes forever.
• Doc and Marty ride after the train which had just left Hill Valley earlier that morning. They then stop it just before it hits the switchtrack with Carson Spur, then hijack its locomotive to push the DeLorean up to 88 mph toward Shonash Ravine so they may both go back to the future ( 1985 ). Marty succeeds in doing so, but Doc, who has gone to Clara's rescue on the accelerating locomotive, and Clara are forced to stay behind. Doc now has the hoverboard and one of the walkie talkies. Since "Clint" was observed stealing the locomotive and is presumed to have gone down with it, he enters the town's folklore as the man who beat Mad Dog Tannen, and Shonash Ravine is renamed Eastwood Ravine.
• 9:00 a.m. Marty departs 1885 and finally returns to 1985.
• Tuesday, December 15 : Doc and Clara are married. [64]
• Date unknown : Doc and Clara's elder son, Jules Eratosthenes Brown, is born. [65]
• Monday, October 29 : Doc and Clara's younger son, Verne Newton Brown , is born. [66]
• While Doc tells his sons stories of his time travel adventures and reads them stories by the fireplace, Clara wishes that she could go to his time period. Doc is happy in his life as a blacksmith and father, but Clara feels restrained by the limits imposed upon her as a 19th century woman.
• After unsuccessfully attempting to generate the amount of electricity needed for time travel, Doc tells the story of how he and Marty first met to his sons Jules and Verne, the latter of whom Clara mentions is only two years old.
• Doc purchased a steam locomotive and begins to converts it into a time train .
• Doc improved the presto logs that he used to send make the boiler burn hot enough to send Marty back to 1985.
• Doc paid railroad workers to lay down fifty yards of track, as he surmises this will be enough length to break the time barrier .
• Date unknown : Doc finishes the Jules Verne train, but is reluctant to show it to his family. Clara tells him that she already knows about it, as he can't hide anything from her.
• The Brown family attempts a trip to 1985 in the time train, but they fail. Just as the train appears to be breaking the time barrier, it crashes at the end of the tracks. Marshall Strickland and his son Roger run to the train to help Emmett and his family. Everyone is alright, but Doc debates whether to just stay where he is. He is sure that Marty would take care of Einstein, and he is happy living with Clara and their sons.
• Clara decides to tell Emmett the truth, and lets him know that she wouldn't be happy if he gave up. She wants to travel through time. He lets him know that time travel isn't just his dream, but one that they both share. Jules and Verne tell him that it is their dream too, and that they all want to travel to see the future for themselves.
• Clara points out a man on a steam tricycle , and Emmett realizes that someone has invented an automobile . The man informs him that the device was created by Léon Serpollet in France , and that he had imported it, at great expense.
• Doc asks him how fast it can go. The man tells him that he had driven it as fast as eighteen miles an hour. Clara and Doc then decide that is a good start, and decide to work together to make their dream a reality.
• Doc examines the technology in the hoverboard, and is able to create a frictionless dynamo that can create multiples of the 1.21 gigawatts needed for time travel, which would improve the time machine's ability to break the time barrier.
• He also surmises that his steam time car wouldn't survive a second trip, so he builds a time parachute , which, when combined with the removable time circuits, flux capacitor, and frictionless dynamo from the steam time car, can be used to travel through time. He connected it to a hot air balloon, which would rise to a distance of half a mile. The person in the time parachute would fall at a rate of 35 feet per second per second, and would reach 88 mph between four and five seconds, successfully reaching the speed needed to break the time barrier and travel through time.
• Sunday, August 13 : Doc Brown left his family for the future in the steam time car, intending to go to 2015 to pick up items he needed to complete the Jules Verne train. The time travel was a success, however due to the 19th century parts he had to use, there was a fluctuation in the space-time continuum. Doc ended up in 2035 instead of 2015, and, although he told his family he'd return seconds after he left, he didn't return home that night.
• Monday, August 14 : Doc has been missing for a day, so Clara writes a letter and brings it to the Western Union, as Doc had done years earlier. She leaves the note with instructions for it to be delivered to Marty at "the highest attainable level of education prior to university, on the first Monday of March, 1986".
• 11:00 a.m. : Marty McFly returns from 1885 and the stopped DeLorean is almost immediately demolished head-on by a diesel locomotive approaching the Eastwood Ravine Bridge in the opposite direction. Marty escapes. He returns home to see everything is back to normal. He then drives over to check on his sleeping sweetheart. She is just as Doc predicted.
• In a virtuous display of uncharacteristic self-restraint, Marty decides not to race Needles, and avoids crashing into a Rolls Royce, thus erasing the future experienced in 2015. Jennifer surprises Marty with the fax she retrieved from 2015, and it "ripples" into a blank sheet of paper. She discovers the hidden truth about time travel, exclaiming: “It erased!” Marty takes her to see the remains of the DeLorean. Marty finds the photograph that was taken of Doc and himself in front of the unfinished clock tower in 1885, only the side of the photograph that showed Doc was burnt away. Doc and his family don't arrive in this timeline.
• The United States military cuts funding to the time travel research being done by Marcus Irving.

• Doc puts a tracking bracelet , using modified 2038 technology, on Clara, Jules, Verne, and Einstein, so that they won't get lost at the fair.
• However, Doc is informed that dogs are not allowed at the fair. Doc puts Einstein, who he calls Fido, due to the fact that Albert Einstein is well known in that time period, into the time train. He then uses a remote control to send the train away.
• Meanwhile, German spies, Fritz and Karl , wonder if Albert Einstein might have shaved his mustache. Thus, they mistake Doc Brown for Albert Einstein, Clara for Einstein's first wife Mileva Marić , and Jules and Verne for Milerva and Albert Einstein's sons Hans Albert and Eduard .
• Einstein manages to get out of the time train. Another grey sheepdog, Queen Jorgensen 's dog Prince Rufio , bites his keeper and escapes shortly afterward. Einstein is mistaken for Prince Rufio, and is taken to the Barataria exhibition.

• When Doc and Clara left the Perisphere to pick up the grey sheepdog the saw, they discovered that it wasn't theirs.
• Karl's associate, Fritz, was trying to kidnap Doc and Clara's sons, Jules and Verne. The boys ran away from him, and walked into the middle of a parade. A man dressed as a superhero named Fair Man was knocked off his float by an elephant, and fell on top of Fritz, allowing the boys to escape.
• In an attempt to find their dog, Doc used a scanner to track Einstein's location. However, Einstein escaped after Laurence took off his tracking collar. When Doc and Clara arrived at the Baratarian pavilion, Prince Rufio's handler, Lawrence, claimed that the Browns had attempted to steal Prince Rufio.
• The police were alerted that Prince Rufio was loose, and the Browns were threatened with extradition by the Baratarian embassy. Clara and Emmett Brown ran from from the Baratarian guards, while their sons, Jules and Verne found the dogs. ***The boys thought that the two dogs were both Einstein, just different temporal versions due to time travel. After both dogs ran away again, Jules attempted to use his scanner to find out where they went, not knowing that Karl had stolen the tracking collar that was around Einstein's neck.
• When the scanner activated, it was discovered by the two German spies, who planned on giving the tracker to Adolf Hitler to aid in his quest to conquer the world .

• Trivia Filmed at the same time as Back to the Future Part III (1990) . It was claimed at the time that in the four years since Back to the Future (1985) was made, Michael J. Fox had forgotten how to ride a skateboard. However, motor skills are not so easily lost (as in riding a bicycle), and Michael J. Fox has since stated that this was an early symptom of his Parkinson's Disease, although the medical diagnosis was not made until 1991.
• Goofs When old Biff steals the time machine to change the past, he returns the Delorean back to 2015 so Doc and Marty would suspect nothing. He should instead have arrived in the alternate version of 2015 just like Marty and Doc went to the alternate 1985. No explanation is given as to why he can return to the unaltered time-line while Doc and Marty can only get to alternate versions of the time-line. In The Big Bang Theory (2007) , the episode The Focus Attenuation (2014) , they suggest that this could be because when Old Biff travels forward, Young Biff hasn't made his first bet that starts the time-line changing yet, thus allowing Old Biff to return to the original 2015. Possible explanation: It is implied that Lorraine eventually got totally fed up with her abusive married life, and shot Biff to death sometime within just a few years after the time when Marty saw them in Alternate 1985 (this is the real reason that Old Biff clutches his chest and crumples to the pavement as he is exiting the DeLorean after returning to 2015, not because his aging body couldn't tolerate the physical stresses of time-warping, as most audience-members would have assumed was happening), removing him and his toxically-greedy influence on the Hill Valley area. The logical "further" idea, therefore, is that the decent-hearted Lorraine --- along with 99% of the other locals, who of course would themselves have also strongly disliked the dystopian wasteland that their community had degenerated into --- would then have banded together en masse --- "in numbers, there is strength" --- and ousted whatever "scum of the earth" officials and politically-influential residents were currently present in the area, and then made sweeping changes for the better to get Hill Valley back to being the peaceful bedroom community that it had been before Biff's interference that had started in the late '50's. Also, Hilldale --- where the McFlys were now living --- was quite a distance from Hill Valley, and so it's possible that Biff's dissipative influence hadn't reached that somewhat-geographically-removed area so much as it had affected his own immediate stomping-grounds.

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

• Crazy credits The theatrical version had a teaser for Back to the Future Part III (1990) . Some later versions do not have a teaser at all, only showing "To Be Concluded", and skip to the credits. Some have "To Be Concluded" followed by "Back To The Future III". Some cable versions retain the teaser for Back To The Future Part III, but, of course, do not say "Coming Summer 1990". It was, however, added back to the film for its digital download and Blu-Ray versions.

The simple reason 'Back To The Future's' screenwriter chose October 21, 2015 to be the day Marty McFly travels in time

October 21, 2015 is "Back to the Future Day."

It's the day Marty McFly and Doc Brown travel to the future in their time machine, the DeLorean, in Stephen Spielberg's "Back To The Future: Part II."

The date was carefully chosen for one simple reason: It was a day, theoretically, the Chicago Cubs could win the World Series.

In the movie, Marty McFly notices while time traveling that the Cubs finally win the world series in 2015, and buys a sports almanac so his younger self can make bets and get rich when he returns from the future. But his nemesis, Biff, gets his hands on the almanac and gets rich instead.

" The Cubs winning the World Series was the most absurd thing we could think of [for someone to bet on]," the movie's producer and screenwriter Bob Gale tells The Wall Street Journal's Mike Ayers . 

"If the Cubs were going to win the World Series, what date would that be on? In 1988, when we wrote this, there was only one set of playoffs, not two. If the World Series was going on and the Cubs were going to sweep the World Series, it could’ve happened on October 21. That’s how we arrived on that day.”

In 1988, the Cubs finished with a 77-85 record. In 2015, they posted a 97-65 mark.  Considering they've dropped the first three games of the NLCS to the Mets, it seems very unlikely that they'll wind up winning the World Series this year.

Back To The Future II: 10 Major Questions We're Still Asking

Many a sci-fi fan can trace their basic understanding of time travel to the Back to the Future trilogy. With a keen eye for how cause and effect can alter a timeline, there’s bound to be questions hiding in plain sight, especially in the three legendary films that saw Michael J. Fox ’s Marty and Christopher Lloyd ’s Doctor Emmett L. Brown ponder the biggest issues one could expect to run into. Tons of people have questioned the events of Back to the Future through such a critical lens, but not as many have turned that sort of eye towards its sequels.

Today, or whenever in the space-time continuum you’re reading this feature, we’re about to take a look at the events of Back to the Future Part II , and ask some major questions we have after watching the movie again. With this legendary sequel fresh in our minds, it’s these issues that we are still scratching our heads over with the second in this series of serialized shenanigans.

How Does Biff Tannen Know How To Operate The Delorean?

While Doc Brown’s Delorean time machine isn’t the most complicated piece of technology, there’s still a bit of a process that goes into putting that baby into gear for time travel. Between needing to know how to enter the date on the keypad, to requiring the knowledge of how to engage both the hover converter and revving things up to 88 miles per hour, you really need to be familiar with how to operate this time machine before you go anywhere. So how did Old Biff Tannen simply step into the Delorean, take it to 1955 to change the future, and come back to 2015 with barely a thought?

Could Biff Have Stayed A “Good Person” If Doc Never Showed Up Again?

The words “Biff Tannen” and “nice guy” never seem to be good bedfellows, but by the end of Back to the Future , a humbled Biff (Thomas F. Wilson) operates an auto detailing service. We’re reminded of this fact at the beginning of Back to the Future Part II , just as Biff sees Doc Brown and his Delorean show up to whisk Marty and Jennifer (Elizabeth Shue) into 2015. It’s only because of Biff remembering this event in 2015 that the central conflict in this sequel kicks off, which has us wondering: would Biff have remained meek and mild if Doc had either stayed home, or was a bit more discreet about his time traveling ways?

What Was Marty Sr. Going To Do That Ended Up Getting Himself Fired?

In Back to the Future Part II both Marty McFly and his son are primed to make horrific decisions that will crash their lives into a mountain of consequences. With Marty Jr. being enticed by Griff and Marty Sr. finding his co-worker Needles (Flea) as his tempter, these decisions would have landed the son in jail and the father in the unemployment line. While the son was spared from a particularly nasty rap for theft, Marty Sr. did the thing, and got himself terminated. But what exactly was this "business proposition" that promised a killer payout?

Would Marty Jr Have Recognized Doc?

Marty McFly Jr was supposed to be intercepted by Doc Brown in Back to the Future Part II , but as we see in the final chain of events, this never happened. Which might have been a good thing, because if the two of them had met, what would have happened? Would Marty Jr. have recognized Doc Brown from all of the stories his father would have more than likely told him? Imagine what the dinner table would have been like later that night with Marty’s kid asking about that wild eyed scientist he used to tell stories about.

Why Is It Ok To Bring A Hoverboard Into The Past, But Not The Sports Almanac?

All of Back to the Future Part II ’s time travel mayhem hinges on Marty’s purchase of Gray’s Sports Almanac, in the hopes of making some easy money on lucrative bets through time. While Doc warns Marty that this sort of thing isn’t exactly wise, considering it screws with the space-time continuum, there’s an outstanding question that needs to be answered in this specific instance: how does bringing a fully functioning Mattel Hoverboard back from 2015 make any more sense? Surely a fully completed piece of tech from the future would skew the timeline just as much as some ill-gotten wealth, right?

Did Doc And Marty’s Trip To 2015 Cause Marty’s Accident In 1985 Prime?

Throughout the course of Back to the Future Part II , and its sequel Back to the Future Part III , Marty’s issues about being called “chicken” are dealt with throughout the past, present, and future timelines in the series. And if it wasn’t for the lessons he learned, he’d have gotten into a music career-ending accident with a Rolls Royce. Which, come to think of it, is never mentioned prior to Back to the Future Part II ; which in turn makes us wonder, did Doc’s initial trip to 2015 accidentally put Marty on the road that would have led to a busted hand and a wedding at the Chapel O’Love?

Why Is Doc Brown So Obsessed With Changing The Future Now?

In Back to the Future, Marty tried to prevent Doc Brown's death by giving him a letter about his future demise. The man swears up and down that he won't read this letter from his young companion, but does it anyway and is spared a horrific death. Could this have turned the scientifically minded, usually careful Doc into a reckless time bandit? The Doc at the beginning of Back to the Future would have never let Marty sniff the future, much less interact with it; and now he's drafting him to course correct his entire family? Did Marty break Doc?

What Was “The Hard Way” Of Dealing With Intruders, According To Biff’s Thugs?

One of Back to the Future Part II’s funniest gags comes when Biff’s thugs threaten Marty McFly with “the easy way or the hard way” when it comes to subduing him. “The easy way”, funny enough, is clubbing Marty on the head with a Blackjack, and shipping him up to the good old 27th floor. The more times we hear that line, the more we feel like asking someone, what exactly was the “hard way," and how illegal is it in the world of Biff Tannen’s assent in alternate 1985?

How Bad Of A Kid Was Alternate 1985’s Marty?

Let’s be honest, the entire alternate 1985A scenario from Back to the Future Part II leaves a lot of questions in its wake. While it’s only a short segment of the entire film, it doesn’t change the fact that the tangent timeline is rich for asking the right questions. One of which has to deal with the fact that alternate Biff mentions oh-so-subtly that alternate Marty apparently has a habit of getting kicked out of boarding schools. So just how bad of a kid was alternate Marty, in order to get bounced from fancy school to fancy school?

Who Kills Alternate 1985’s Biff?

Our last two questions are major ones, especially when it comes to hardcore sci-fi fans . As dyed in the wool Back to the Future Part II fans will tell you, there’s an infamous deleted scene where Old Biff returns to 2015, only to fade away into obscurity. It’s the reason he’s doubled over in pain when he returns the Delorean, but the final shot of Biff disappearing was trashed in the final edit. With that moment still lodged in our minds after numerous sessions with the deleted scenes, we’re still stuck wondering: who killed Biff Tannen? Yeah, the suspect list is long, but that’s what makes it all the more interesting to ask.

Is Back To The Future’s Alternate 1985 Set In The Watchmen Universe?

The final question Back to the Future Part II is a fresh one, and you can blame HBO’s hit series based off of the Watchmen universe for its inspiration. In 1985A, Marty reads a newspaper that, among other things, talks about President Richard Nixon seeking a fifth term of office. The last time we saw that sort of history play out, we’d won Vietnam because of Doctor Manhattan, so time travel doesn’t feel totally out of place in this hypothetical overlap.

This doesn’t even begin to cover the numerous questions we could still ask about Back to the Future Part II , as well as what we could go on to discuss in reference to Back to the Future Part III’s conclusion to the series. But for now, we’ll stay in the here and now, with these major queries outstanding and just waiting for answers.

The Hover Cars in Your Favorite Sci-Fi Movie Might Actually Be Possible

It all comes down to magnets.

In 1989, we were told the transportation of the future would float — as long as you weren’t over a body of water.

That’s the year Back to the Future Part II was released, which, as anyone who was a child in the late ’80s or early ’90s will tell you, was the cool one. Not because of plot, necessarily, but because that’s when Marty McFly (impersonating his future son) first took off on a hoverboard. But in the streets around him, you also had floating and flying cars.

The year is 2024 now, and we could be facing down a second Biff Tannen presidency, so where are our floating cars and hoverboards? Could we even make those? The answer right now is a solid… kind of, but it would be difficult and come with unintended consequences. And that’s because of how we’ve accomplished it thus far.

Levitation, How Does It Work?

The fundamentals of levitation are relatively easy. A paper published in Physical Review Applied last fall demonstrated the ability to make a magnet hover in place with, of all things, a Dremel tool. It built off a discovery first made by Hamdi Ucar in a paper published in Symmetry in 2021. Ucar’s discovery initially made Rasmus Bjørk , who led last year’s paper, very skeptical of the research.

“I browsed through it, and then decided that looks really long and it was published in some obscure journal that I hadn’t heard of before, so I didn’t give it a lot of credibility, it didn’t look sort of entirely plausible,” Bjørk,a professor at the Technical University of Denmark (DTU), tells Inverse. Two weeks later, a colleague contacted him about the paper, and Bjørk told him he didn’t buy it. “Then he wrote back, ‘But have you seen his YouTube channel?’”

“You need a high-speed motor and some magnets.”

That channel has, to date, 219 videos of various objects levitating. Eggshells, test tubes, walnuts, and lots and lots of bearings, many looking like they’ve been taken on a cellphone. It also, according to Bjørk, relies only on classical physics, nothing elaborate needed. It could really have been discovered anytime since 1865, when James Clerk Maxwell first described his theories on electromagnetism that proved foundational in our understanding of magnetic fields. “It doesn’t even require a very elaborate experimental setup,” he says. “You need a high-speed motor and some magnets.”

This new levitation method was real, but how did it work?

If you’ve played with magnets before, you know that there are positive and negative poles; opposites attract, and two magnets oriented to the same pole repel. Joachim Hermansen , a Ph.D. student in medical technology at DTU who has worked with Bjørk on the project, tells Inverse that the dremel needs enough space from the magnet and to reach a steady state in its energy output.

“What happens is basically that the magnet on the dremel acts as both a repelling force to the magnet when it gets too close, and ... an attractive force when it gets (farther) away,” he says. And as the magnet tumbles over and over, it creates a sort of stable levitation. But the magnet has to continue to spin for this to really work. “It’s gyroscopically stabilized the same way a spinning top is stabilized, so it doesn’t fall over because of gravity,” Frederik Laust Durhuus , a DTU physics Ph.D. student also involved in the research, adds. According to Rasmus, the poles of the magnet and the dremel need to align in order to reach this hovering state.

Hovering At Scale

“Maybe sometime in the future we will be able to make something that could do that kind of thing.”

Now, an egg and a dremel is one thing. But how do you get a hoverboard or floating car out of the deal? In principle, a large object doesn’t need as fast a rotation from a proportionally equal dremel, according to the group. (“The magnetic fields don’t care about sizes as long as everything is relatively the same size,” Bjørk says.) But gravity does care, making stabilizing larger objects more difficult. Basically, the heavier the object, the more likely it is to fall out of levitation due to the effects of gravity.

Because of this, the most immediate application is using the technology to hover things around, what Durhuus calls “contactless object handling.” “As long as the object is magnetic, you can do that with quite a lot of dexterity, having it fixed in the air and then moving around the rotating device,” he says.

“The technology I have right now requires magnets on both ends, so you need magnetically paved roads.”

Bjørk says that a basic problem is trying to get an object to levitate above one of the magnets. “You can’t levitate anything above anything like the hoverboard, which would be super nice if you could,” he says. If you try, it throws off the delicate balance of this magnetism. And even if you magnetized the roads, which you’d have to do to hover objects above them in this, it could have unintended consequences on other electronics or just magnetized metals in general. This is especially true with the kind of very strong magnets you’d need to make this work on a human scale in the first place. “So that is not necessarily the way to go — instead more research to improve and understand the phenomenon is needed,” Rasmus says.

But by understanding the particulars of this technology, new understandings of magnetism could usher in breakthroughs that bring us closer and closer to the hoverboard.

“Maybe if we understand this, maybe sometime in the future we will be able to make something that could do that kind of thing,” Bjørk says. “If we study these things in depth, what else can we discover? So, I’m not ruling it out, but the technology I have right now requires magnets on both ends, so you need magnetically paved roads.”

In other words, the movie got one thing right — if you get caught trying to hover over water, the bullies are going to get you.

‘Back to the Future II’ Gave Us One of Godzilla’s Weirdest Storylines

When are we getting Godzilla on a hoverboard?

The Big Picture

• Back To The Future II inspired Godzilla vs. King Ghodorah , leading to the only Godzilla film featuring time travel.
• Time travel allows films like Back to The Future and Godzilla vs. King Ghodorah to explore intriguing "what if" scenarios.
• The unique twist of time travel in Godzilla vs. King Ghodorah changed Godzilla's motives and created a memorable installment.

Time travel has been a staple trope in cinema for decades , and it really became popular in the 1980s with films like The Terminator , Star Trek, and Bill and Ted's Excellent Adventure . It allows audiences to use their imaginations and dream of what the future could look like, with its endless possibilities. But perhaps the most famous entry into the time travel genre is the Back To The Future trilogy, which follows Marty McFly ( Michael J. Fox ) and Doc Brown ( Christopher Lloyd ) as they travel to various decades, both in the past and future.

In the first film, Marty, a teenager living in 1985, gets trapped in the 1950s when he uses the DeLorean time machine to quickly escape a terrorist group that is after Doc Brown after he promised them plutonium. He finds the Doc Brown of the past to help him figure out how to get back to his own time. In the second feature film, Marty has to travel to the future to stop his kids from falling down a dark path. It turns into a huge dystopian tale as Biff Tannen ( Thomas F. Wilson ), the notorious villain in every film, gets ahold of the DeLorean and makes some changes to the past. But did you know that Back to the Future Part II directly influenced one of the most weird and wonderful Godzilla films?

Back to the Future 2

After visiting 2015, Marty McFly must repeat his visit to 1955 to prevent disastrous changes to 1985...without interfering with his first trip

How Did 'Back To The Future II' Inspire Godzilla vs. King Ghodorah?

The director of 1991's iconic Godzilla vs. King Ghodorah, Kazuki Ômori , said in a 2022 interview with Medium that the success of Back To The Future II made Godzilla co-creator, Tomoyuki Tanaka , think about the possibilities of a Godzilla adventure featuring time travel. Even though he was initially against the idea of time travel, thinking that it was too much for him and that if you add time travel, there are too many possibilities. According to Ômori, Tanaka saw that Back To The Future II had higher attendance rates than his Godzilla vs. Biollante in 1989, which led him to consider and pursue the idea. Thus, it gave us one of the best of the Heisei era (refers to a political period in Japan), Godzilla vs. King Ghodorah . It is still the only Godzilla film featuring time travel.

Time Travel and Godzilla Are a Match Made in Heaven

In Godzilla vs. King Ghodorah, Godzilla, usually the film's antagonist, becomes the world's savior as he defeats the golden-scaled, three-headed King Ghodorah . In this installment, the Futurians travel back in time from the year 2044 to warn the people of Japan that Godzilla will come back to ruin them. Their plan of action is to travel back to 1944 with Terasawa ( Kôsuke Toyohara ), psychic Miki Saegusa ( Megumi Odaka ), and Professor Hironori Mazaki ( Katsuhiko Sasaki ), a paleontologist, and stop Godzilla from ever being created by the 1954 Castle Bravo H-bomb test. Their mission succeeds, but little do the people of 1992 know that the Futurians plan on creating another monster of their own using three Dorats to create King Ghodorah.

We later figured out that the Futurians were part of a political party known as the Equal Environment Earth Union. Their goal was to extort Japan because it was becoming increasingly corrupt. Once the travelers return to 1992, they see Ghodorah terrorizing the nation. So, their best solution is to recreate Godzilla to defeat the creature. It turns out that Godzilla wasn't gone after all but was in the depths of the ocean, and after Godzilla absorbed the nuclear submarine, he became even bigger than before. Godzilla and King Ghodorah duke it out in an epic battle , Godzilla decapitating one of Ghodorah's heads, and they both plummet into the ocean. But we know Godzilla won by the monstrous scream he lets out at the film's end, letting audiences know he shall return.

Robert Zemeckis Wanted Ronald Reagan To Be in ‘Back to the Future Part III’

This bizarre plot of Godzilla vs. King Ghodorah was the first and last of its kind. It had time travel, giving the film a new twist and changing Godzilla's motives. During the earlier films, Godzilla was a symbol of nuclear war, a world gone wrong, and something humans couldn't take back after creating it . But Godzilla was absolved of this wartime connection when he was deliberately created using the nuclear submarine; Godzilla became a force to help Japan save their nation. But since the time travel aspect seemed to be popular enough, why didn't they make another one featuring time travel? Maybe to keep the uniqueness of the film, or because once is enough. Either way, the film is one of the better installments within the ever-growing franchise.

Time travel films like these work so well because they explore the possibilities we ask ourselves every day. What if you could go back and fix this horrible mistake you made? What if you could take back what you said? How would your life be different? Films like Godzilla vs. Ghodorah , The Terminator, and Back to The Future explore these questions differently but always make audiences consider the possibilities. An idea they all explore is the effect fixing the past has on the future. Even with the technological advances in these films, it's interesting to see how they explain it to someone who has no idea what a hoverboard or cyborg is.

What Other Films Inspired 'Godzilla vs. King Ghodorah'?

Back to The Future II wasn't the only influence for Godzilla Vs. King Ghodorah . Kazuki Ômori told Medium that some of the biggest inspirations for the film were The Terminator and Aliens . The influence of The Terminator is evident; like in Godzilla vs. King Ghodorah , The Terminator ( Arnold Schwarzenegger ), who is a cyborg assassin, has to go back in time to save the future. His target is Sarah Connor ( Linda Hamilton ), but he ends up befriending and protecting her when secrets about the future are unraveled. Similar to The Terminator , everyone in Godzilla vs. King Ghodorah seems to have ulterior motives, like the Futurians who end up creating King Ghodorah and John Connor ( Edward Furlong ), who was the one who sent the T-1000 assassin, giving both films good plot twists.

It's almost time to evacuate another town as we reunite for another adventure in the MonsterVerse . Godzilla X Kong: The New Empire , premieres next month and will pit Kong and Godzilla against a colossal threat that will challenge the existence of the monsters and our own.

Back to the Future Part II is available to rent on Amazon.

Best time travel movies

Many films come with an escapism element, the ability to separate ourselves from our current timeline and reality to imagine an alternate time or place. It is a common feature in entertainment, which can serve as an outlet to explore our fears, dreams, and hopes for the future. Many movies take their characters on a journey to the past or future in hopes of teaching profound lessons, offering new perspectives, or simply presenting a challenge or a solution to a problem that they are facing in their current timeline. They expand the reach of what we think is possible in our current lives.

To celebrate these innovative and time-twisting tales, Stacker compiled data on the top time travel movies to come up with a Stacker score—a weighted index split evenly between IMDb and Metacritic scores. To qualify, the film had to involve some sort of time travel (be it literal, like "Back to the Future," or metaphysical, like "Donnie Darko"), have a Metascore, and have at least 5,000 votes. Ties were broken by Metascore and further ties were broken by IMDb votes. These films are some of the most memorable and culturally significant time-travel adventures in American cinema.

13 back to the future plot holes & time travel paradoxes (& which ones have been fixed).

Back to the Future is full of time travel plot holes and paradoxes, and while these 13 are the most apparent, some of them have actually been fixed.

Like all time travel stories, Back to the Future has several plot holes and time travel paradoxes, and these 13 are the biggest ones. Due to the nature of time travel and constantly changing timelines, Back to the Future has to keep track of a lot of small details, but some manage to slip through the cracks. Luckily, the Back to the Future trilogy has fixed some of these plot holes and paradoxes, although others are still in existence.

The Back to the Future trilogy mainly takes place in four different time periods. 1985 is the present across all three movies, while Marty and Doc travel to 1955, 2015, and 1885 throughout the trilogy. Due to the constant traversal between the past, present, and future, all kinds of alternate Back to the Future timelines are opened throughout the franchise, leading to some serious paradoxes. So, here are the 13 biggest plot holes and paradoxes from the Back to the Future series as well as which ones were fixed.

13 George & Lorraine Should Recognize Their Son As Marty McFly

One of the biggest plot holes in the Back to the Future series is that George and Lorraine McFly should have definitely realized that their son looked exactly like Calvin Klein in 1955. Although they didn't know Marty's alternate 1955 persona for long, he played a big role in both of their lives. Because of this, it is strange that neither of them ever mentioned how familiar Marty looked, although it makes sense that they wouldn't leap to the idea that Marty was a time traveler.

12 Marty McFly Shouldn't Have A Hairdryer In 1955

One plot hole that frequently gets brought up is that Marty McFly shouldn't have a hairdryer in 1955, although this has actually been fixed. In the first film, Marty puts on a sci-fi costume in an attempt to scare the 1955 version of George McFly. However, part of his costume is a handheld hairdryer, which shouldn't exist in 1955. The creators of Back to the Future answered this question , explaining that a deleted scene featured Marty pulling a hairdryer out of a suitcase that 1985 Doc put in the DeLorean.

11 The Clock Tower Should Work After Marty Gets Back To 1985

The broken clock tower is one of the most important elements of Back to the Future , with it ceasing to work after being struck by lightning in 1955. However, Marty and Doc change history by rerouting the lightning to Marty's DeLorean, sending him back to the future. Because of this, the clock tower should work when it is seen in Back to the Future Part II , although it is still broken for some unexplained reason.

10 Old Biff's Fate Was Never Revealed

A massive plot hole from Back to the Future Part II is that Old Biff's fate was never revealed, with him simply walking away after returning to 2015. This is another detail that is actually explained by a deleted scene. Since Old Biff gave Young Biff the sports almanac, this changed the future, meaning that Old Biff would cease to exist. Because of this, a deleted scene showed Old Biff falling over and fading away, although it was cut from the final film.

9 Marty Didn't Have To Steal The Almanac On November 12, 1955

The second half of Back to the Future Part II is pretty tense, with it following Marty as he tries to steal the sports almanac from Biff on November 12, 1955. Marty chooses this date because it is when Old Biff gives Young Biff the almanac, but choosing November 12, 1955, adds a lot of unneeded stress to the situation. Biff didn't use the almanac until several years after he got it, meaning Marty could have simply traveled to a time when it was unoccupied and taken it that way.

8 Old Biff Went Back To The Wrong 2015

Another paradox surrounding Old Biff is that he returned to his original 2015 timeline after giving Young Biff the sports almanac, but this actually shouldn't happen. Since Old Biff changed the future, 2015 should be completely different, but it looks the same when Biff returns. The creators have also explained this, saying that the timeline would either change around Old Biff or that the neighborhood he was in simply looked the same despite the timeline changes.

7 Old Marty & Old Jennifer Shouldn't Exist In 2015

Back to the Future Part II introduce Old Marty and Old Jennifer, introducing one of the series' biggest paradoxes. 1985 Marty and Jennifer meet 2015 Marty and Jennifer when traveling to 2015, but their older selves are from a timeline where they didn't travel to 2015. Since 1985 Marty and Jennifer did travel to 2015, this version of their older selves shouldn't exist and they should have been replaced by an Old Marty and Old Jennifer that did travel to the future when they were younger.

6 The DeLorean Time Travels Without Going 88MPH In Back To The Future 2

In Back to the Future II , the DeLorean time machine spins around before time traveling away, breaking the rule that DeLoreans must go 88 miles per hour to time travel. As it turns out, though, this problem has been fixed. Bob Gale and Robert Zemeckis have explained that the DeLorean doesn't necessarily have to be moving forward 88 miles per hour, and since it was spinning at that speed, it was able to time travel.

5 There Are Two DeLoreans In 1885

One of the franchise's most famous plot holes occurs in Back to the Future Part III 's 1885 timeline. During the film, there are actually two DeLoreans in the same location: Marty's DeLorean as well as the DeLorean Doc used to travel to 1885. Although they are both broken, Doc and Marty could have combined parts from the two cars in order to make one that worked, solving the film's problems much faster.

4 Doc Brown Should Know About Einstein In Back To The Future 2

In Back to the Future Part III , 1955 Doc smirks when he learns that his future dog is named Einstein. However, Einstein was in the tape that Marty showed 1955 Doc in the first film, meaning that he should have already known this. This plot hole has also been fixed, with the creators explaining that Doc simply didn't see or remember this part of the tape.

3 Doc's Tombstone Shouldn't Exist In Back To The Future 3

In Back to the Future Part III , Marty sees Doc's tombstone from 1885, opening up another paradox. Since Marty went back in time to prevent Doc's murder, the tombstone shouldn't exist, meaning that 1985 Marty would have never seen the tombstone and gone back to 1885 in the first place. This massive paradox ruins the movie's story, although the tombstone had to exist in order to serve as the story's inciting incident.

2 Clayton Ravine Should Have A Different Name If Clara Lives

In Back to the Future Part III 's main timeline, teacher Clara Clayton falls into the Shonash Ravine, causing it to be renamed Clayton Ravine. However, when Doc travels back in time, he falls in love with Clara and consequently prevents her from dying. When 1985 Marty sees Doc's grave, he is in the timeline where Clara lived, yet he still knows about the Clayton Ravine legend. Since Clara never died, Marty's knowledge of Clara's death shouldn't exist, and it should still be named Shonash Ravine. However, the franchise's creators have clarified that time travel doesn't affect memory, which is an odd but valid solution.

1 Doc Should Know That "Mad Dog" Tannen Is Going To Kill Him

The final major plot hole and paradox in the Back to the Future series occurs in the third movie, where Doc is killed by "Mad Dog" Tannen. The version of Doc that is killed comes from 1985, meaning that when Marty tells 1955 about Doc's death, 1985 Doc should know as well. Because of this 1985 Doc would be able to prevent "Mad Dog" Tannen from killing him, negating Marty's reason for traveling back to 1885 in the first place. While many of Back to the Future 's plot holes and paradoxes are confusing, this one is one of the most straightforward.

Viewers in what's called " the path of totality " saw the moon completely block the sun  — an opportunity those in North America won't have again for 20-plus years. The next total solar eclipses in North America are not anticipated until 2044 and 2045.

"A total solar eclipse is one of the most spectacular things anyone can see in their lifetime," Virginia Tech astrophysicist Nahum Arav told CBS News. The eclipse "looks like a black hole in the sky," said Arav, who watched the paths of totality of eclipses in 1991 and 2017.

Monday's eclipse started around 11:07 a.m. PDT on the Pacific Coast of Mexico, and then moved into Texas . The eclipse's visibility tracked  through 15 states  — Oklahoma, Illinois , Ohio,  Pennsylvania , New York , Vermont ,  New Hampshire  and Maine , among them — before heading northward into Canada and then exiting North America.

Even with spotty weather in some states, millions of people from coast to coast saw a partial solar eclipse, in which the moon partially covers the sun. However, only those within the path of totality experienced the darkness of the total solar eclipse. 

When is the next total solar eclipse in the U.S. after the 2024 eclipse?

Solar eclipses happen about twice a year, said Arav. "Eclipses happen all over the Earth evenly," he told CBS News — but noted the timings when they occur are not regular. That means  eclipses can occur within just a few years, or every few decades, in North America.

Before the eclipse in 2017, the last total solar eclipse to cross North America was in 1979 . That was the first eclipse whose path of totality crossed the entire continent in 99 years. 

Even though eclipses may seem to occur randomly, scientists can pinpoint exactly when and where they will happen.

"There is no ambiguity, as we know exactly where it will land," said Arav. 

There will be eight total solar eclipses visible from North America in the 21st century, Arav said, with one occurring about every 12 years, on average.   

The next total solar eclipse to cross North America is predicted to occur on Aug. 23, 2044 , NASA said. However, the path of totality from this eclipse will only touch three states, according to  The Planetary Society, a nonprofit organization dedicated to public interest in space.  

This next eclipse will mainly be observed in Canada, Arav said. 

Path of totality for the 2044 total solar eclipse

The 2044 eclipse will start in Greenland on Aug. 23, 2044, and will continue its path through Canada. 

The 2044 total solar eclipse will be short, mostly appearing in Canada. It will be visible from three states in the U.S.: Montana, North Dakota and South Dakota.  

The path of totality will cross Williston and Dickinson, North Dakota, and Great Falls, Montana.

Path of totality for the 2045 total solar eclipse

The next solar eclipse that crosses a significant portion of the continental U.S. will be in 2045, said Arav. That year, a solar eclipse will darken skies in parts of the U.S., Haiti, Dominican Republic, Venezuela, Guyana, French Guiana, Suriname and Brazil. 

In North America, the 2045 total eclipse will be visible in many states as it moves from coast to coast. The eclipse will start in California and move east to end in Florida, similar to 2017, Arav said. 

There will be numerous U.S. cities where eclipse watchers can view the total eclipse, including Reno, Nevada; Colorado Springs, Colorado; and Orlando, Florida.

Future solar eclipses in North America after 2045

Scientists have predicted eight total solar eclipses will appear in North America in the 21st century.

"Natural phenomena are like a Swiss clock," Arav said. "We know exactly when and where they will appear."

After the 2044 and 2045 total solar eclipses, the next total eclipses in North America will occur in 2078 and 2099.

May 11, 2078

This total solar eclipse on May 11, 2078 , will pass over the southern United States.

Cities include:

Atlanta, Georgia

New Orleans, Louisiana

Charlotte, North Carolina

Virginia Beach, Virginia

Sept. 14, 2099

This total solar eclipse on Sept. 14, 2099 , will cross a wide swath of the United States.

Minneapolis, Minnesota

Milwaukee, Wisconsin

Chicago, Illinois

Columbus, Ohio

Fargo, North Dakota

When is the next total solar eclipse in the US after 2024 and what is its path? What to know

The highly anticipated 2024 total solar eclipse will cross North America on Monday , giving millions of sky-gazers the chance to see a rare cosmic event that won't be viewable again for 20 years.

The eclipse's  path of totality  will travel over a portion of northern Mexico before entering the U.S. It then it will cross 13 states  from Texas to Maine, where the spectacle is expected to attract huge crowds.

If you aren't lucky enough to be in the path of totality this time around, you will have another chance - you'll just have to wait until the 2040s.

When is the next total solar eclipse visible from the U.S.?

It will be 20 years before there's a chance to  witness a total solar eclipse  in the United States again.

According to NASA, after Monday's total solar  eclipse , the next one viewable from the contiguous U.S. will be on Aug. 23, 2044.

2044 total solar eclipse path of totality

Unfortunately, the 2044 total  solar eclipse  won't have the broad reach across the U.S. as the 2024 eclipse.

The path of totality during the 2044 eclipse will only touch three states, according to the Planetary Society, a nonprofit involved in research, public outreach, and political space advocacy.

The eclipse will begin in Greenland, sweep through Canada and end around sunset in Montana, North Dakota and South Dakota.

2045 solar eclipse

While the 2044 total eclipse will only touch three states, a 2045 eclipse will have a more robust path across the U.S.

Expected to occur on Saturday, Aug. 12, 2045, this solar eclipse will trace a path of totality over California, Nevada, Utah, Colorado, New Mexico, Oklahoma, Kansas, Texas, Arkansas, Missouri, Mississippi, Louisiana, Alabama, Florida, and Georgia.

A partial solar eclipse will also be viewable in 35 other states, according to National Eclipse.com

What is a total solar eclipse?

Any celestial object like a moon or a planet that passes between two other bodies can create  an eclipse  by obscuring the view of objects like the sun.

In the event of a solar eclipse, the moon comes in between the Earth and the sun, blocking its light from reaching a small part of our planet. Partial eclipses, when some part of the sun remains visible, are the most common, making total eclipses a rare sight to behold.

Total eclipses can lead to a period of darkness lasting for several minutes, during which time nocturnal animals stir while confused birds and insects may fall silent, NASA says.

When a solar eclipse reaches totality, people are able to see the sun’s outer atmosphere called the corona, which is usually obscured by the sun's bright surface. This offers scientists an uncommon opportunity  to study the corona .

Totality also offers spectators a chance to gaze upon the spectacular sight with the naked eye, though  proper  safety  glasses  are still required for the rest of the time.

What states are on the 2024 eclipse path of totality?

Mexico's Pacific coast will be the first location in continental North America to experience totality, which is expected to occur at about 11:07 a.m. PDT,  according to NASA .

As the moon's shadow will northeast, totality in the U.S. will begin in Texas at 1:27 p.m. CDT. The path will then cut diagonally across the country, traveling through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont and New Hampshire.

The eclipse's path is expected to end in Maine at 3:35 p.m. EDT before visiting the maritime provinces of Canada, according to estimates.
