Wrong! Young Doc in BTTF 3 saw his grave and would remember it when he's old, but ONLY in an alternate reality which they just created by seeing the grave. The inconsistency that you should mention is in BTTF 2, after Biff changes his past in 1955, when he travels to the future he should've ended up in an alternate 2015 instead of the one he came from, in which case Doc & Marty would have no Delorean anymore.
Chris Just I think that changes in 2015 were taking place at the moment Biff was returning the DeLorean and Marty, Doc and Jennifer were returning to the time machine... maybe time-space changes were taking a few more moments to adapt to the changes made in 1955 by Biff
Dimi oh yes.. the 3 years between 1955 and 1958.. mmm
Dimi That makes absolutely no sense. It doesn't matter if old Biff had left instantly before his young self made bets. Time will still continue to move forward and by he arrives in 2015 everything young Biff had done would have already taken effect. Old Biff SHOULD have landed in an alternative 2015! Chris is right. This was a mistake.
They explained this in the FAQs on the box set. Biff DID come back to alt-2015, it's just that this area of Hill Valley looked basically the same. Notice how Biff doesn't return until AFTER they get Jennifer out of the house. This was intentional. You're meant to assume that the area has now changes to the new timeline, it's just similar enough that they don't notice cause they're already out of the house.
passthelimejuice it's kinda confusing...
It’s always confused me how Biff changed the timeline and then returned to his original 2015 rather than the new 2015 where he’s a millionaire.
If you've read the comics, you'd know evil maniacal Trump Biff dies in 1986, hence Biff being erased as soon as he gets back. 29 years have past with Lorraine in charge. Maybe things have gone somewhat back to normal
Also, after George punches Biff, Biff is still a bully in that timeline, yet when they go back to 1985, Biff is George's feeble little worker. I guess it took him a little bit of time to transform into the weak Biff?
This is what I came to write!! After Biff gave his younger self the almanac when he traveled to the future it would be the alternate just like Doc said which is why they had to go to the past to stop it from happening….
@@BillGraperGood point. I didn't pick up on that.
@@mevestillerpotential paradox. IF Biff is offed by Lorraine, or, 2, assuming hes not, Old Biff goes out of existence soon after- after rich birds first bet. Perhaps in the time lag, theres a window of opportunity for D and M to see Biff there.
Back the Future 2 should never have happened. Doc took Marty to 2015 in order to help Marty's son. But they didn't have to travel to the future in order to save him. All Doc had to do is go back to 1985, tell Marty what is going to happen to Marty's son in the future. With that knowledge, all Marty has to do is make sure that he never let's his son hang out with Biff Jr. The future hasn't happened yet. So it can be changed from the past, as long as you have the knowledge of future events.
80's Nostalgia Guy Griff*
It definitely should have happened. Yes there are many plot holes, but it’s such an epic, fantastic movie. It’s impossible to not have plot holes in time travel movies
Your wrong remember how doc says if you notify someone of their future events it will ruin the timeline so he coudent of and also how did doc and marty go to the future and see themselves cause when you leave your time and go to the future your past self won’t be their because you left your own timeline and never came back
Griff was the grandson of Biff.
idk about you but i would forget about that by the time 2015 rolled around
The main flaw is at end of first one where Marty and Jen go from 1985 to 2015 and able to see themselves. The very beginning of part 1 shows Einstein the dog going 1 minute into the future where he was not there for the entire minute. So if Marty and Jen jumped from 1985 to 2015, realistically they would have arrived at a future where they had been missing for 30 years.
No, because they then go back to 1985, immediately after the time they left
@@josephmslyallI love BTTF2 & it was BTTF 1's idea at the end to go 30years into the future but other than wanting to have a fun future reality film with HoverBoards, FlyingCars etc...and make the film title "BackToTheFuture" make sense like it does in 1 & 3 for a valid reason. BTTF2's reason for going into the future isn't good. Do they just think they'll forget about that incident in the future they want to change? Also it would be less risky to just wait and tell your kids what to avoid rather than risking Jennifer seeing herself & fainting & having to hide from your future son and Biff noticing there's 2 people who look the exact same.
@@FootkerSnookballThe ending to 1 was a joke, a fun stinger to end a stand alone film.
The studio was going to make a sequel with or without them, so they went back at it.
They would've never had Jennifer be a part of a scene forcing them to write her into the story (they have her sleep the whole goddamned movie), and they weren't interested in going to the future at all (the future sequence was decent, but they zipped through that shit as quickly as they could).
You are correct
@@josephmslyall but that assumes that they successfully returned. What if something went wrong and they didn't? I know, plot armor and all, but let's say you can't assume success in getting back home.
There's an easy solution here. Immediately upon arrival in 2015, go to the library and start looking at newspapers from 1985 to see if there's an article about a 17-year-old named Marty McFly disappearing without a trace. If you find such an article, print it out and head straight back to the DeLorean since you now know this is destined to be an ill-fated expedition - and you weren't going to find your kids there anyway since you disappeared 30 years ago! Head back home immediately, and as you arrive back in 1985, you'll see the article fade away and get replaced with an announcement of the Hill Valley Bingo Tournament or something.
If you don't see such an article, then proceed with the expedition, since you know you're going to return safely. But maybe print out a couple of newspapers from the week or two following your departure and make sure nothing foreboding shows up in them as you go along ("teen goes missing," Marty McFly "obituary," etc). If so, get right back to the DeLorean and go straight home.
Of course, if we're going to get into plot holes, did BTTF2 have to occur at all? Couldn't Doc simply have told Marty and Jennifer what was going to happen in the future and to be on guard for it? That would accomplish the same goal (preventing the bad things from happening), with ~30 years rather than a couple of days to make that happen, and with much less disruption to the space-time continuum (including Old Biff getting the almanac). (Note that "knowing too much about your future is a bad thing" is a ship that has already sailed, since by going to the future Marty sees with his own eyes exactly what would happen in the future; if anything he found out way more about his future than he would have had Doc simply sat him down and explained what would happen 30 years from now. If Doc were that concerned, he could also have written Marty a letter with instructions not to open it until 2010 or so.)
its a good vid, but im surprised nobody has spotted the big time travel plot-hole in back to the future two, if biff steals the time machine, goes back in time and therefore creates a different 1985, how come he comes back to the normal 2015 timeline and returns the time machine back to Marty and the doc which results in them going back to the altered 1985; surely that 2015 would automatically change as soon as Biff changed the timeline in 1955 along with Marty and the doc changing with it, hopefully this makes sense
edit - i love this film franchise, my statement was based on what is shown in the theatrical release and what i personally consider logical regardless of deleted scenes. in my opinion back to the future is speilbergs best work, but depending how u view time, it could be considered flawed
BloodAngel500 They would lose the Delorean altogether and be stuck in 2015 because Doc would go to the loony house and not have the chance to even create and finish the time machine in the first place. So, it would just stop there with an Apocalyptic Biff world, no Delorean, and no way to change it. I dont think Zemeckis wanted it to be a sad story.
BloodAngel500
dude there is another problem
if biff took the time machine went back to 1955
if he change the past
then the whole incidents will change
marty went to Switzerland for higher education in alternate 1985
so he won't meet doc
marty won't go to past , future etc etc won't buy that book
so the thing is , marty and doc won't go to the future so old biff can't take the time machine and go back to 1955
so how cum he became so rich if we see it according to the time line
aaaaahhhhhhhh
It isn't a plothole as Old biff go back before young biff change anything in Theory, young biff didn't even believe in the book when old Biff left so only when he figure out things changed.
I know he said that, but that's bullshit as the fixed Jennifer was the one that they left there.
I think it works because if you're not in the time machine, it's your reality, meaning maybe it changed but it didn't matter because they weren't in the area where Biffs hotel was. (Note in the alt 1985 Lyon Estates looked kinda similar.
And This Is Where My Brain Stops Working
Brain.exe stopped working
why doesn't martys parents remember their son being calvin from 1955?
There was a deleted scenes where George actually thinks about it but he just shrugs is off
There are people I went to school with 30 years ago that I considered good friends. People who I hung out with almost every day for _years..._ yet all these years later I can’t remember their faces. I imagine it would be even harder to do that with someone you only knew for one week.
Nelson Leesong - Yes, the _words_ stuck with him but that doesn’t automatically mean that he’d be able to perfectly recall Calvin Cline’s face 30 years later.
Tugg Speedman that's spelled as "Klein" not Cline, but they both (Lorraine and George) should have a bit of DéJà Vu, everytime they look at Marty and remember the way they met in the better 1985, knowing who it was that brought them together in 1955.
Steve Pelt - I’m just saying that unless they have photographic memories, they’re not going connect the face of someone they knew for one week 30 years ago with that of their son who they’ve seen grow and change over the course of the past 18 years.
Given how Marty doesn’t just blink out of existence but rather slowly fades away in the first movie, it seems that time is malleable and takes a while to settle. Things don’t really change prior to a time jump even after another one guarantees another one, they settle and then get disrupted again. Which kinda fits with Docs closing remarks of “Your future hasn’t been written yet, no one’s has, the future is whatever you make of it, so make it a good one.”
Maybe it was such a heavy "Great Scott" moment, the doc's brain melted & he didn't figure it out.
The biggest time travel error and one that I think no one ever really mentions is, how the hell are Doc and Marty able to go into the future and see their future selves? If they leave 1985 to go to 2015 they should have arrived to a Hill Valley where they have been gone for 30 years in the same way that Einstein "skipped over that minute to arrive at this point in time."
The only other option is that they returned to 1985 and lived out the years as normal. But then their future selves would have been very aware of their presence in the future. The existence of their future selves would be an indication of if they return to 1985 or not. No future selves and chances are your not getting back. If there are future selves then your going to go back to 1985 but the future selves would be aware of their past selves running around. A bit of a paradox.
Indeed.
GodofFrankie I've thought the same thing
I've always wondered that myself.
The possibility of two of you existing at the same time breaks the laws of physics....and this folks, is what makes time travel impossible. Energy (and therefore matter) cannot be created or destroyed....
The last 30 seconds is the only important part of the video: since 1955 doc becomes aware of his future of becoming stuck in 1885 and dying, he should have been prepared for it.
One problem with this idea is that in the movie the time travelers do not immediately (or perhaps ever) gain the memories of their own modified past. This is seen many times, such as in the first movie when Marty returns to 1985 and is not aware that his mom is thinner, his brother has an office job, Biff is a sheepish auto detailer, and Marty has the truck in the garage. Marty is shocked because he has retained memories of his original timeline past instead of having new memories of this new past.
There are other ways this could work as well.
This is right. Was cruising the comments for anything like this.
There's a delay for time to "catch up" to what's been changed. In some movies it takes longer depending on how the movie needs it to happen.
But for sure, 50s Doc could have spent the next 35 years preparing for nearly anything.
Why the hell didn't he fix the time circuits?
Or the starter?
He could have copied the Mr Fusion too.
AND he knew about the hover conversion.
There should be another movie.
also where is the marty from the new timeline?
@@zouLworm That Marty traveled back to 1955. It’s shown in the movie.
It is not 1955 Doc. that's 1985 Doc who went back to 1885 then back to 1985 in his train all 1955 Doc know is m Marty went back to save his future self. 1955 Doc knows is he creates a time machine.. and it needs 21.1 Gigawatts
@@zouLworm Yeah, you'd think that should have had some ramifications. However it would have most likely been catastrophic, I'm guessing that's why it wasn't elaborated.
Basically the Marty from the alternate 1985 (Lone Pine Mall) timeline travels back to the exact second, and exact place that Marty from the beginning of the movie, from the (Twin Pines Mall) timeline appeared. Basically the two arriving at the exact same time would have killed both Martys and destryoed both Deloreans.
What’s funny is that this video only needed to be a few seconds long. Just say “Why didn’t old Doc in BTTF3 remember the tombstone his younger self saw?”
Pretty much! Also it skipped 2-3 other time travel inconsistencies on the way to arrive at that conclusion. But who doesn't like someone drawing timelines on a white board! Good times!
because he never looked for his tombstone, since the doc that died was the older doc how could a younger doc have the memories of what he did when he was older? there's another reason too but i explained it in my other comment.
@@mcdude9578 no older doc is in 1885 and younger doc saw the tombstone so older doc should have the memory but it doesnt because if he did have the memory he would have known that he dressed mrty in that stupid outfit. instead of asking who.
Because this doc from 1885 cant remember it because the 1955
Doc saw the tombstone, when 1985 doc already went to 1885, so it had no affect on his mind
Why didn’t the timeline collapse when Old Biff steal the time machine?
2:20 He’s married to marty’s mom? I am so pissed at you sir, her name is loraine
Llhorreyneh* Please spell it right atleast.
Kr0ll3x Gaming dude i forgot i even commented 🤦🏻♂️
@@P1_D yeah two years is a lot I suppose
@@P1_D damn after 2 years your here. Wait which timeline are you in ? 😂😂😂😂😂
Reetam Chakraborty idek anymore 😂😂
There's a rule of thumb I came up with when time traveling.
That is, anytime you go back in time its an alternative timeline.
BTTF only shows this in BTTF2 when Doc draws it on the board and called it alternate 1985.
The reality is, the first time Marty went to 1955, its an alternate 1955.
How? .... You can tell because the original one does not have a Marty in existence. Only the alternate 1955 does. (They're 2 separate instances of 1955, one with Marty, one without.)
You brushed over this and said it wasn't relevant.
The fact of the matter is, when he goes back to 1955 from 2015 its an alternate. When Doc goes back to 1885 its an alternate (docs existence now creates an alternate 1885)....
Rule of thumb.... anytime you go back its a new timeline an all of these make up a multiverse.
When you draw it out using alternate timelines you can clearly connect them together on your board.
There is no Marty in 1855. He wasn’t born yet.
@@RED-isTheNewBLACK Exactly.
Which is why when Marty travels there, his existence there is what causes it to be an alternate 1885 as opposed to the original 1885 where there isn't any Marty
And also, 1985 was alternate when Marty returned from 1955, his parents were different, Biff was different
@@RoyalW1979 There is no "Multiverse" in BTTF. There is only one single timeline that changes itself when alterations are made.
@Quadinaros Look I loved The Adam Project too lol. But the fixed timeline concept is flawed and so confusing.
This view to me is like when we thought the sun revolved the earth. To say there is one time line is just forcing all of existence to revolve around our own POV.
If you go with these mechanics, you get stuck with paradoxes. The grandfather paradox in particular. multiverse resolves the grandfather paradox.
BTW. Doc Brown drew part of a multiverse in BTTF2 on the blackboard in the library. He explained they were in an alt 1985 after old biff changed 1955 (again).
That's not one timeline at all
Back up more. The timeline changed initially when Marty returned to 1985 the first time in the first movie. THAT 1985 is the real 1985A. Nobody acknowledges this because everyone was happy with the changes made.
You mean the part when Marty fixed the timeline on 1955 about improving his father to be a better person, while everything seems better?
Yeah, I guess you're right about the first temporal replacement.
he was just trying to make his parents stay together so he and his siblings are born. thats its all it did was make his father a little better. and his mother,
I did the timeline and as I see it, the whole series ends in a 5th alternate 1985.
You have to assume that Everytime someone traved back to 1955, they would have created a new 1985 to go back to and finally after returning from 1885, Doc and Marty would have created a final (5th) 1985
A lot of it is to do with the fact that each time the Time Machine goes into the past, the Timeline it came from is overwritten due to the Ripple Effect.
BTTF is plain and simple. Marty McFly comes from an unsuccessful family and accidentally goes 30 years into the past. Whilst there he prevents his parents' first meeting which starts a ripple effect that will eventually erase him and his siblings from existence. However Marty and his siblings are not immediately erased because the key moment to his parents falling in love with each other is when they kiss at the Enchantment Under the Sea dance which gives him 7 days before the Ripple Effect catches up with him. When Marty returns to the future he see's a Time Remnant of himself (who comes from a successful family due to Marty's actions in the past) being sent back to 1955 in order to keep the Timeline stable. The reason 2 Marty's don't appear at the same time in the past is because Successful Marty supersedes Unsuccessful Marty, this is also the reason we don't see multiple Einstein's when he's sent ahead 1 minute. Marty has returned to a different future than the one he came from because in this Timeline his family turn out successful i.e. Timeline 2.
BTTF 2 is where things start to get a little complicated because Doc (Timeline 2) goes to the future at the end of BTTF, but he takes 4 more trips before coming back to 1985. He first goes back to 1938 to purchase Action Comics #1 to sell in the future creating Timline 3 and 2015A, he then returns to 2015A modifies the Time Machine, and finds out Marty Jr. gets arrested, he then goes ahead and finds out the ordeal with Marty Jr. ends up destroying the McFly family, he the goes back to 1985 to fetch Marty and Jennifer to sort out the ordeal with Marty Jr., but the moment he arrives in 1985 he creates Timeline 4 and 2015B so from that point on it's Marty (Timeline 1), and Doc (Timeline 2). After sorting out Marty Jr's ordeal, Jennifer is accidentally taken to her future home and whilst Marty and Doc are getting her out Old Biff takes the Time Machine back to 1955 creating Timeline 5, 1985A, and 2015C. When Old Biff returns after altering his own history he's actually returning to 2015C because in a deleted scene as soon as Old Biff returns he is erased from existence because it's theorized that Lorraine eventually finds out Biff murdered George so she murders Biff sometime in the late 90's and because Biff travels past the year of his own murder the Ripple Effect instantaneously affects him. This gives Hill Valley just under 20 years to reconstruct itself after Biff's hold on it so when Old Biff returns from 1955 it looks no different, but if Marty and Doc were to go back into the future McFly residence no doubt there would be somebody else living there, most likely the African American family who are living in the McFly residence in 1985A. When Marty and Doc return to what they discover to be 1985A they create Timeline 6 and thankfully because they're from alternate timelines they're not instantly erased from existence but it would only be a matter of time before they were, but after finding out when history was altered, Marty and Doc go back to 1955 creating Timeline 7. Marty and Doc had to let Old Biff (Time Remnant) give the Sports Almanac to his younger self, so that thinking his plan had succeeded he'd then take the DeLorean back to his now erased future in order to keep the Timeline stable. At this point people ask why Old Biff wasn't erased immediately after giving his younger self the Sports Almanac, and the simple answer is because time hadn't caught up with him yet. Old Biff gave the Sports Almanac to his 18 year old self, so time wouldn't catch up for at least another 3 years because Biff wouldn't of been able to gamble until he was 21, hence why Old Biff was able to return to 2015C, but the Ripple Effect immediately erased him from existence due to going past his own death in the 90's. After destroying the Sports Almanac, 1985A was erased and replaced with 1985B. Then when the Time Machine is struck by lightning sending it back to 1885 it creates Timeline 8. So in the end you've got Marty (Timeline 1 & 2 (Time Remnant)), Doc (Timeline 2), Biff (Timeline 6) 1955 Biff (Timeline 7), Old Biff (Timeline 4/Time Remnant), 1955 Doc (Timeline 7 & 8). After being sent back to 1885 creating Timeline 8 it also creates a Ripple Effect causing Marty to receive the letter Doc wrote in 1885 moments later.
BTTF 3 has Marty and 1955 Doc find the Time Machine that Doc (Timeline 2) buried 70 years ago. Afterwards Copernicus finds Doc's grave and that he died 1 week after writing the letter he has delivered to Marty by the Western Union. 1955 Doc (Timeline 8) has seen the tombstone so no doubt his future events will work out differently, but Doc (Timeline 2) is not aware of this. There's also the fact that the Ripple Effect doesn't change a time travellers memory since Marty (Timeline 1) still remembers his unsuccessful family before altering his family history, Doc (Timeline 2) is unaware of his fate despite his younger self viewing the tombstone, Doc doesn't know it was his younger self who dressed Marty in the cowboy outfit, also Doc and Marty still had their memories of 1985A despite erasing it. After going back to 1885 creating Timeline 9, Marty prevents Doc's death so the tombstone is erased meaning it will never exist for 1955 Doc (Timeline 9) so his future events will also play out differently. However after Marty returns to 1985 it takes Doc 10 years to build the Time Train which gives him plenty of time to fix any changes that were made during the 6 days that Marty was in 1885 e.g. He could place a fake tombstone in place of the real one for Marty and 1955 Doc to find whilst they're recovering the DeLorean from the Delgado Mine so that Marty will go back to 1885, plus Doc was the only one in the photograph Marty and 1955 Doc find of him in the archives standing in front of the 1885 clock, so he has to make sure the photograph either doesn't end up in the archives, or the photograph that Marty and 1955 Doc come across only shows him because Marty stood with him when the photograph was taken after he went back to 1885.
Basically the BTTF Trilogy doesn't all revolve around one Timeline. When the Time Machine lands in the past it automatically changes events due to the fact it not being there in the previous Timeline. As for the Ripple Effect it always catches up with the Time Traveller last which is why they're not immediately affected depending on the circumstances.
Notes:
Marty Jr. Paradox.
This is where we all start to get a major headache because by preventing Marty Jr. from going to prison, when Doc's younger self comes to 2015 he won't find out about these events because they were prevented therefore he'd have no reason to go back to 1985 to fetch Marty and Jennifer in order to prevent Marty Jr. from going to prison, which would then cause the events that get him sent to prison etc. so I'm foreseeing 2 possible outcomes. The first outcome I see is that by averting Marty Jr. from going to prison, Doc has unintentionally turned his younger self into a Time Remnant so when he arrives in the past on October 26th 1985 he's come from an erased Timeline, and then due to the several more times the DeLorean goes back he'd be bringing Marty and Jennifer into another erased Timeline.
The 2nd and more logical outcome is that bringing Marty and Jennifer to the Future is no doubt what's keeping the Timeline stable. Doc could've stopped the whole event from coming to pass on his own by knocking Marty Jr. out with that sleep inducing device, but then the Time Paradox I just mentioned would come into effect making the Timeline unstable with worse consequences because it would only involve Doc. However bringing Marty and Jennifer to the Future is most likely how Doc intended to keep the Timeline stable because with Marty already knowing what happens to his son by seeing the newspaper, and Time Travel not affecting his memory after the event was changed, when Doc comes to the Future for the first time, Future Marty can tell Doc's younger self what is to occur, so he can go back and fetch Marty and Jennifer to bring them to the Future to prevent it.
Future McFly Family.
A lot of people keep asking how the Future McFly Family exists when Marty and Jennifer have been brought to 2015 because you've got one theory that suggests if 1 were to go to the future, they'd end up in a future where the Time Traveller in question has been missing for the amount of years they've travelled ahead. Then you've got another theory that suggests if 1 were to go to the future you'll find your future self and can find out how your own history plays out.
The missing for so many years effect seems to only happen when someone travels to the future for the first time, seeing as how Doc is not seen or heard from for 30 years when he travels ahead to 2015. Whereas the meeting your future self effect seems to only happen if your future is set. In this case we've got both effects happening. As I just mentioned, Doc is not seen or heard from for 30 years after he goes ahead to 2015. However when Doc returns to 1985, he comes from a future where Marty and Jennifer are married and have a family of their own, so their future is set, hence why bringing their younger selves to 2015 has no effect on their future history. If 1 of them had died whilst in the future, then their future history would be effected e.g. When Jennifer met her future self, if she fell and hit her temple, it would've most likely killed her, affecting her future history and causing a Time Paradox.
You wrote a whole bible in here XD
@@XatD26 Ya 😂😂
I still think doc in 1885 should have remembered his 1955 self sending Marty back. It is the same as BTTF 1 when Marty returned to 1985 and older Doc remembered the events and had the letter.
Well, maybe. But how was the time machine, while hovering in 1955 and being struck by lightning, able to travel back to 1855 without reaching a velocity of 88 mph?
@@XatD26 Order Of St. Chronos. 😂😉
That's not an error. It's well established in the movies that the "ripple effect" only moves forward along the timeline, and not backwards. Once Doc travels back to 1885, his memory will be replaced with the original ones he had before. This also happens to Marty in the first film. Marty travels back to 1955, and changes how his parents fall in love. Marty then is raised with a differing story of his parents' first meeting. He travels back in time to 1955, and if the ripple effect moved backward, then Marty wouldn't have known what the heck he did to ruin the timeline when he pushed his dad out of the way of the car. Also, the Marty we actually follow throughout the movies would have had his memories replaced with new ones if the ripple effect moved backwards. There's no plot hole. The ripple effect only moves forwards, and that's why Doc didn't know he was going to die.
Thank you
But doc did know because he had the letter?
Remember by changing the timeline in the first movie, Marty only remembered his original time line. He was confused when he saw Dave in a suit at the end, and noticed how his parents were healthier and more in love... and he didnt remember owning a truck. By that logic, older Doc in 1885 doesnt know about the tombstone...
How did biff go back to the original timeline and not the alternate timeline after changing the past?
Now that’s the real error
It undoes the entire trilogy. Old Biff alters the original 1985 where Doc and Marty meet and test the Time Machine. So there’s a paradox with even having the Time Machine go back in the first place.
The whole concept of backward time travel opens a huge can of worms. We're all traveling forward through time right now.
It always bothered me that when they got stuck in 1885 because the Indians arrow ripped the fuel line , why didn't they just take fuel out of the delorean that Doc arrived in?
He never said the car was out of fuel in his letter, just the the time circuits were broke and suitable replacements won't be invented until 1947.
Dave Egginton Funny posted the same plot hole in bttf 3. Lol!
Dave Egginton
You normally take the fuel out of a car you mean to store for a while, never mind 70 years.
Name of the Rose yes, this.
Doc knew there wasn't any gas in the area for a while. He would of siphoned it and saved it.
Name of the Rose
Yeah of course you do. I'm not saying he would have left it in the car but like Tyler said, he would have stored it.
Thinking about it, why didn't he just go to western union and edit his letter to tell Marty to bring a can of gas?
Here's one that always bugged me...When Doc , Marty & Jennifer travel from 1985 to 2015 at the start of part II there shouldn't be a future Marty or Jennifer because they both skipped over 30 years to instantaneously arrive in 2015. So my theory is that they would have been gone (missing) for 30 years.
You are right, but then the BTF series wouldn't have been as Fun to Watch, and we wouldn't have all of these Fun Paradox's to think about. Also, Gale/Zuckerberg never planned on BTF sequels, and had to quickly come up with something Fun to Watch... 'Paradox's Be Damned'
I think it's clear that whenever they alter something there's a sort of ripple effect and it actually takes time for it to take effect. So when something happens it's not like looper where the effect is immediately known and seen. It takes time for it to catch up. Everything is taking place on one timeline but is constantly being altered so by the time anything catches up it could have already happened. So they would have to go back in time to stop it. It seems imformation/memories aren't linked to the timeline.
You're all forgetting the absolute MAIN time travel error. Marty goes from 1985 to 2015....and sees his older self, at home with the family etc etc. How? Technically, he's been missing for 30 years.
that's exactly the main problem of BTTF 2
I thought about this in the past. My thought process is that even though he knows it’s going to happen, he lets it happen anyway so the timeline doesn’t get disrupted
This wouldn't be a problem, though. Every time someone goes backwards in time, it makes a new timeline. For example, Marty and the delorean make a second timeline, which includes clones of him and the time machine. At the end, the versions from the second timeline disappear and the timeline 1 versions take their place. By the time Doc reads the letter, this is the doc from timeline 7. The doc in 1885 is the timeline 2 doc, the same one Marty saves at the end of part 1. So since the letter is only read by the timeline 7 and 8 docs, the doc from timeline 2 never read it. That's also why saving Clara doesn't wipe his memory of Clayton Ravine's name since it would only affect timeline 8 doc.
Who’s says doc didn’t know? Doc knew that he needed Marty to get the Time Machine back to 1885. That’s added motivation for Marty
I was so hopeful for this video. And then I watched it until the end. And then a shit ton of question marks literally appeared above my head like in the cartoons. And then I was like, “that was it? I just lost five whole minutes.”
There’s loads of flaws from Marty stopping Doc getting shot, to Biff going back to the same 2015 instead of the altered one.
Someone should make a high-quality funny video where Doc and Marty try out all these alternate approaches, such as 1955 Doc just remembering, "In 2015 I gotta make sure Biff doesn't steal the car", stuff like that, and then seeing the crazy and paradoxical results. Lol
did you realize that they had 2 time machines in 1885? they could get the gasoline from the old car that was hidden in the mine and come back to 1985 without all the troubles.
Doc would have drained all the fuel from the DeLorean before placing it into storage. Otherwise after 70 years the fuel would gum up and would require replacement of the entire fuel system. So unless Doc stored that gasoline someplace else, it was already gone. And even if he did store it, it was already over 9 months old by the time Marty arrived; by then, unless you added fuel stabilizer (which, admittedly is mostly alcohol so Doc might have been able to make some with distillation equipment available in 1885), it's a crapshoot as to whether that fuel would start the car, or cause damage to it. That being said, they did experiment with various forms of alcohol, and ended up destroying the fuel system anyway, so it could have been worth a shot if the gas had been saved.
I never considered that last part. I thought you were going to point out the fact that Doc says they can't go back to the 2015 they'd just left from the alternate 1985 because they would arrive in an alternate future, yet Biff seemed to have no trouble returning to that version of 2015 after he had set events in motion back in 1955 to change the timeline.
When Marty change his parents future 1985 is an alternate universe
They certainly wouldn’t be living in Hill Valley after George became a different person after punching out Biff in the modified 1955. The new George was now a successful sci-fi author and woulda moved up to better digs.
Incorrect, because why did 1885 Old Doc ask Marty "What idiot dressed you in that outfit?" He would surely remember that it was himself from 1955.......
Best comment section ever! :)
I'm sure you mean "worst"
My head hurts
@@jasonrice26 ikr
Yeah man! I love it!!! Back to the future fan page as well. Hours of time travel brain twisting fun!
anybody cares to reply after 2 fuckin years 😂😂?
Why didn't 2015 change when old biff came back from 1955?
True. Doc, Marty, and Jennifer should have disappeared right away. Since Doc is now in an institution, Marty is at a boarding school, and Jennifer never meets Marty.
Señor Deadpool
Nature, uh, finds a way.
By 2015, all the bad that Biff created had been fixed to good again (or relatively good, we don't know that Biff is not responsible for Hill Dale becoming so terrible).
Different timelines tho.
It did. When Old Biff retured to 2015 he was pale and exhausted, he was in pain like Marty when he was about to disappear in the first movie. There is an extended scene when Old Biff disappears from existence after returning to 2015, meaning the future is changing.
It could have something to do with time ripples small stuff changing the future slowly it took Dave a long time to vanish completely from the photo in the original movie however it's possible that the ripple effect takes a linear passage stating with more recent events first because Dave was the oldest he was being erased from existence first and the alternate timeline would finally exist with Marty being erased from existence. now 1955 to 2015 is about 60 years so it would theoretically take longer for the ripple effect to change 2015 because by the time Doc and Marty got back to 1985 the alternate timeline had taken over from 1955 had taken enough time to change 1985 to 1985A.
Oh wait! I see the error. When doc died in 1885, he can’t be alive in 1985 for seeing his own grave
Actually, that might explain why he changed his mind in after he tore up that note Marty gave him in 1955, warning him about the Libyan terrorists.
Well, he can, since the Doc in 1885 is the older version of the one in 1955, who will grow up, and invent the time machine in 1985. He'll still see it, until of course the ripple effect catches up and the tombstone disappears.
To me, the point of bttf3 isn’t to go back and save doc but rather to bring him back to 1985. However, doc still could have changed the fact that he’d be stuck in 1885 and prepare with a better built Time Machine that wouldn’t malfunction or one that if it did, he could fix it with the tools in 1885
Lorraine mentioned that she liked the name Marty, why didn’t she give that name to their first kid? They didn’t know there would be someone else to name Marty.
Everything you outlined was pretty accurate, except that the thing to keep in mind is, when Marty travels back to 1885, he's basically saving version B of 1985 Doc from not being able to live out his older years, that's all, since version A of Doc died at the beginning of Part I. He's not going back to save him from ever existing (like Marty did for himself in Part I). So it's not about "Old Doc (1985) vs Young Doc (1955)", it's about Marty wanting to save Doc B from 1985, so that he can live out his retirement years, nothing more, nothing less. At least that's what the creators tried to establish in terms of time travel--"Multiple Worlds Theory", or multiple dimensions, meaning several versions of Marty and Doc can exist along alternate timelines
I’ve always wondered why when young doc and Marty see old docs grave and it says “loved by Clara” or something along those lines but the only reason doc met Clara in 1885 is while him and Marty were checking the tracks and bridge for the Delorean to go back to 1985 which wouldn’t of happened yet if that makes any sense
If Marty hadn't been there, he was supposed to have picked her up when she arrived as the new school teacher according to the town council person.
There many possible ways that Doc could have met Clara. It's kinda like in Terminator, John Connor would have been born regardless of whether Reese time travelled. Sarah could have been knocked up by any man and still gave birth to a John.
Great to have these comment sections to clear up what can be cleared up. Doc volunteered to pick up claira at the station, so that wasn't one of the errors. The error was doc not knowing he was going to get killed by Mad Dog once 1955 Doc learned of it.
@@jesskoffman the doc in 1955 that sees his own grave never goes to 1885.
Also the fact that when biff steals the time machine,old biff should of been erased after giving himself the book. So that would also mean the time machine would be erased too because doc never made it in that timeline so old biff wouldn’t have stolen it in 2015. Which mean that 2015 they saw should have erased and that Marty and doc would just disappear with it
Correct! Been saying this for years
Einstein goes 1 minute into the future if he doesn't see himself like Marty because he's time traveled too.
You hit on your own mistake around the 2:35 point--the "kinda" new timeline. Two points:
1. There are several timelines, a new one with every jump backward--i.e., "Butterfly Effect."
2. These are distinct biological organisms. They aren't suddenly imbued with new memories when entering/starting a time line (see movie "Frequency" for examination of that sort of thing). The Doc who went back to 1885 is not the same Doc who saw the grave.
Putting these together, we don't know how Doc's life and actions would have changed due to all of this. Indeed, he might have either told Marty more back when working on it, or even--how's this for the classic paradox?--never invented it in the first place.
As one Tom Wilson is quoted as saying..."it's a movie."
A TIME MACHINE movie.
The biggest plot hole is that Marty would HAVE no kids,or future self waiting for him when he got to 2015, because he didn't live through those 30 years. He just disappeared from the world in 1985 and reappeared in 2015.
You may be able to use time travel to meet your past self, but you can't use it to meet your future self, because you always take yourself with you.
Also, what kind of name is Biff?!
Biff is an abbreviated name. His given name is Buford Ivan Fitzgerald the IV.
+The Cardboard Box Then what's his grandson's name Griff stand for?
Why does Griff call his Dad Gramps? Who is Biff's wife that had Griff? Why would Griff call him "Gramps"?
UNKPCRIDE because griff is biffs grandson not his son
Andy Anderson then if Griff is Biffs grandson, who/where is Biffs Son that was needed to make Griff? There's a gap
You and all of B2tF neglected to mention how Old Biff from the future returned the time machine to Marty and doc while they were in the alternate timeline's future, after giving himself the almanac.
In theory once old Biff stole the timeline and gave 1955 Biff, future George should have disappeared from the dinner table
No, because it takes 1955 Biff time to use the almanac - he doesn't use it straight away. Once he uses it, even after a day, Marty and Doc in 2015 would have already returned to 1985. It works within the film's logistics, even if it's confusing.
We don't really see what happens in the house. Biff comes back from the past after they get Jennifer out of the house.
4:35 he probably just saw a ghost lol
I thought that it was weird. He obviously saw something, but he goes back to his theory like nothing happened. Maybe a time traveler rather than a ghost?
He was probably just reading the script or notes to remember for what he’s talking about
Haha
His mom was calling him from the dining room: "stop fiddling with that thing and come in here and eat your dinnerrrrer!"
The second movie creates a time paradox Doc is always talking about. Biff changing the past result in Doc being sent to an Institution and Marty being sent away to boarding schools. Therefore, the events of the time machine can never happen and therefore Biff cannot steal one to make his future better.
It would, but, you have to remember, they are still continuing the "timeline" that the current Marty and Doc are on.
The doc’s that we’re present in both versions of 1985 were different people with different experiences of meeting Marty for the first time. 1 had no knowledge of Marty before Marty met doc for the first time, and 1 had to keep quiet about his memories of meeting Marty in 1955. Same it’s Biff in 1985. One got punched by George Mcfly, the other didn’t.
The doc that went back to 1885 is a different doc than the one in 1955 that sent Marty back to 1885. This doc may go on to meet Marty and keep quiet about everything until Marty experiences it for himself. This doc may remember the grave, but he also might still act surprised or even forget.
The doc that went back to 1885 wouldn’t have the memory of the grave or of getting a tool from a mysterious stranger that looked like himself in 1955. Since 1985 doc wouldn’t have altered memories just like Marty didn’t have altered memories when returning to the improved 1985.
TL;DR. They are different versions of the same character, but the original doc didn’t have the memory of seeing his own grave in 1955.
No, the timeline error occurred earlier, in 2015 when Biff stole the Delorean. When Biff returned to 2015 after altering the time line in 1955; he would've returned to an alternate 2015 that would not have Marty nor Doc waiting for the DeLorean. Biff altered 1985 to the point where Marty never met Doc. This means, when Biff went back to 2015 from 1955, it would've been a different 2015, void of Marty or Doc. So just to reiterate, you're wrong. The first time line error occurred in 2015.
Correct. Been saying this for years. 2015 Biff actually unravels the fabric of time, because he prevents Doc from ever making a Time Machine. Explosions!
@@JoshuaDanger ik it's been 6yrs since i first made this comment.. but yes, that's 100% correct..
the delorean time machine would've never been created.. ergo, biff would've never been able to return back to 2015..
The only way the movie works, is if they're not actually traveling back to linear timelines in history, but instead traveling to completely alternate (timelines & or dimensions) that are just similar enough, albeit different, from the ones they're originally traveling from..
There are alternative timelines so there are multiple docs’
Technically yes, but like the 2 Doc & Marty's in 1955 the timelines intersect thus forming one continuous timeline especially from Marty's perspective.
biff's return trip would have been an alternate
future.
I would argue that Everytime they travel is an alternate reality and they never changed the 1st time but went to an alternate reality where his father was doing better
💯 Very true. It seems we only see alternate time lines as major disrupters but they can indeed be smaller changes too which have butterfly effects within them.
@@rommee Yes in my opinion I feel like anytime they activate the machine is a disruption and opens an alternate reality, I'm a believer that even if you time traveled and never even got out of the vehicle it's still a butterfly effect because something from the foreign timeline has entered to where it doesn't belong, what do you think?
@@zeedapezant Agree. Plus the time- traveller wont always personally be aware of any changes they have made. There can be physical, emotional and psychological changes made on the people and environment. Ie. A person looking for a car parking space may see the Delorean parked in the far diistance and decide it's one too many cars on that road and will go to another road to park there instead OR a person chooses to walk on another pathway because the Delorean looks suspicious there etc. etc.
Actually BTTF series has THIS issue.... at the end of BTTF 1 Marty rips up the letter telling Doc that he'll be shot by terroritsts (libians) and when Marty comes back to 1985 after Doc gets shot Marty goes to him and Doc has a bulletproof vest and has the letter on him taped up put together and Marty says "What about all that talk about knowing too much about your own destiny"... Doc says: "What the hell"....
The issue here though is in BTTF 2 at the end when Marty says "Yeah, I know Doc, you did send me back to the future, but I'm back... back FROM the Future".... then "Great Scott" etc... etc.... this is changing things again.... will Doc still TAPE UP the letter putting it back together AND will Marty and Doc still even meet at the mall at that JC Penny parking lot and have everything back the same way.... I doubt it. And even after the 1st movie without BTTF 2.... It's interesting how when Marty travels back to 1985 at the mall he see's himself and Doc there..... sure it was awesome and real, but makes you wonder now that 1955 Doc was informed he made a time machine that DID work if he'd even be at the mall in 1985 showing his delorean time machine to Marty as he did.
So that's why it REALLY makes you think... NOT only about time travel if it's possible or not but how crazy the scenarios are in terms of IF it ever WAS possible what would be the effects. You could keep traveling back over and over and meet more icons or clones of yourself ininitely or who knows what the true effects or possibilities of time travel would be.
Lastly, I love BTTF and whether it's good or has questions about it's story... it's all fun and entertaining to me. But I have yet to wonder about anyone thinking about the letter Marty wrote Doc that he later taped up .... and wondering what ultimately happened with Marty coming back from the Future.
Hmmmm.
True. In the first movie, once Marty goes back to 1955, interacts with the Doc, and affects the timeline, it is impossible that Doc would be able to recreate the 1985 scene exactly. Doc actions would be completely different. Once he knows about time travel, everything he does until 1985 would change the timeline.
You notice that the letter Doc shows is not the exact same one that Marty wrote.
Neme of the Rose It's the same letter, that the whole point.
when 1955 doc showed Marty the drawing of the flux capacitor and Marty showed him the working capacitor he knew then it worked. So if it took that long to build the time traveling car then yea he would be showing it in 1985 if that's how long it took. but i do agree the way he showed the delorean would change.
AMPDOG2 actually the DeLorean began manufacture in 1981 or 82, so I'm sure Doc had smaller working inventions to sell the patent rights on, and afford a brand new one then, to make the time machine out of, instead of a used one in 1985, so he probably could have made one out of a Lamborghini or any kind of futuristic looking car for that matter. Lol
At the end of Back to the Future II, Marty should have just gone back in time a couple minutes in order to warn Doc that he's about to get struck by lighting if he doesn't get out of the DeLorean. Failing that, Marty should have gone back in time to 1885, found Doc, and then the two of them could have gone back to 1985 in the working DeLorean Doc had buried.
And, at the beginning of Back to the Future II, Doc, Jennifer, and Marty should all should have disappeared from 2015 after Marty managed to get Griff (instead of Marty's son) arrested. With future history changed, there would have been no reason for Doc to have gone back to 1985 at the end of Back to the Future I.
Marty did go back in time to 1885 to rescue Doc in the working DeLorean, but it was hit by an arrow and lost it's gasoline. The real mistake is he should have gone ahead in time to prevent all of the incidents that led to Doc being there in the first place....but that would have been a whole different movie, ,and we would have never found out that Clint Eastwood was the one who kicked Mad Dogs ass.
Why didn't 1885 Doc and Marty patch the arrow hole and then syphon gas out of the other delorean? The delorean that Doc had already hidden in the mine?
John Fakename: You solved the problem. Why didn't Doc think of that??? But then again, why didn't Marty just go back a few days, and warn Doc about the lightening strike? Then there would have been three working Deloreans to choose from.
Time paradoxes and shit like that
Because there wouldn't be any gas in it.
I think I am the only one to know something about this movie that know one else does. In 1885 there should have been 2 Deloreans! One Doc's accident brought him there and then Marty pulls it out of a cave and takes it back! So when Marty's car loses gas Doc's car still has gas in it!
He busted the fuel line and said it would take a month to rebuild. But maybe if he chose that safer but teduous route , to siphon the gas out of the delorean he hid in the cave rather than trying whiskey, you are on to something!
You have to understand that the 1955 doc is from the original family tree. The future Doc went back to 1885 and he created a new family tree, so therefore the original doc from 1955 would not remember him being in 1885 because he hasn't time traveled yet.
The movie falls apart when you realise doc- after witnessing Marty's son's incarceration with his involvement with Bif's grandson, decides to not just tell future Marty a day ahead about his son's pursuing dilemma. Allowing Marty(then in the future present) to simply have his kid stay inside and away from Bif's grandson and his gang. But instead electing to go all the way back to a unrelated timeline with Marty in the 80's to attempt a more complicated measure of resolving a problem that would not even equate teen Marty to have to be involved with.😩That's when in logic it starts go(to) fall apart.
Yeah, but then the 2nd movie is pretty boring. lol
@@mae2759 I suppose...but then. Doc could just bring him along to hang out in the future and see flying cars and hoverboards.🤣
Well it falls apart in my opinion when Biff from 2015 steals the time machine, goes to 1955 and changes things. He should have never returned to Doc and Marty in 2015 like. He should have returned to an alternate 2015. It doesnt make sense that he rturned to a normal 2015 and then Doc and Marty go back to an alternate 1985. Bad break in the story line right there.
it could be possible that it takes longer due to a ripple effect it took longer for Marty to start disappearing in 1955 than his brother did. it would take a lot more time for the 1955A timeline to take over 2015 then 1985 where it would take 60 years for 1955A to catch up to 2015 it took 30 years to change 1955A to 1985A
Workin'angel97
Not really. Search for BTTF 2 deleted scenes here on CZcams, there's a scene where the old Biff disappears right after getting back to 2015
It does change, but they're in a bad part of town and the change is unnoticeable, assuming 2015A is as seedy as 1985A. Biff is dead because Lorraine shot him years earlier, so he did disappear in a scene cut from the movie.
and if old Biff returns to the alternate timeline 2015, not only will it be one in which he is dead, but one where Doc and Marty never came to in the time machine, but both changes will make it impossible for him to have gone back to 1955, thereby erasing the whole premise for the movie and returning everything back the way it was before any of this happened??
So sometime between the better1985 and that timeline's 2015, Doc brown died, if the timeline was altered, then why did Marty and Jennifer's kids turn out to be stupid criminals, in the "entire family being destroyed in a chain reaction" statement?
Yeah, except in the letter doc sent to 1955, he repeats he is content with living in 1885 and for Marty not to go back to get him. We hear 1955 doc say this explicitly and is repeated after doc saves Marty from Mad Dog Tannen in 1885. There also would have been no way to know that he was killed by Mad dog because if Marty hadn't gone back to save him, he would have been shot by a single bullet on the 5th and died of lead poisoning two days later. The actual attempt on Docs life at the towns clock tower event was completely by surprise. Both Marty and Doc, with for knowledge of this event suspected he would have died on Monday; That's why when Mad dog Digs his little pistol into his back he says: 'Your early'.
Here's one to think about. Doc goes to 2015, then returns to 1985 to get Marty. Since Jennifer is there, Doc brings her along too, cause she saw the time machine. Now it's Doc, Marty, and Jennifer in 2015. Problem, since Marty and Jennifer were absent from the timeline from 1985 - 2015. They both disappeared in 1985, and reappeared in 2015. They weren't in the timeline to get married and have kids. Doc arrives alone 2015, Marty and Jennifer are married with kids. Doc arrives with Marty and Jennifer 2015, there should be no Marty and Jennifer too see, cause they were absent from the timeline for 30 years.
My Guess: This problem, and many others, can be solved using the "ripple effect" theory. i.e. Anytime you see multiple Marty's and Doc's at the same time, it is just temporary until time catches up -- the "older" versions will eventually be 'removed from existence' when they are replaced by new versions. So you could say that the old 2015 versions were 'starting to fade away' when they saw them.
Me: I can’t sleep
CZcams: do you want to watch Back to the future Time travel errors?
Me: sure.
I think I've found an error or a time paradox. In bttf part 3, Doc and Marty go to the Delgado mine to find the deloreon. When Marty discovers Doc's grave stone, it mentions is love Clara. Now the way Doc and Marty meets Clara is because they go to scope out the train site where Clint Eastwood revene is, then clara horses are running towards the edge of the cliff and they save Clara. Now the only reason Doc and Marty are at Clint Eastwood revene is because they are trying to figure out how to get back to the future. So how could Doc meet Clara if marry never went back to get Doc? Doc would have met Clara at the festival later that night. STRANGE!!!
UNKPCRIDE
well there is another possibility
doc might have roaming that area just for sightseeing , then he saw claira , then he saved her
It is mentioned in part 3 that Doc was going to the Train Station to meet the new teacher. She didn't die because he met her and she didn't travel by herself to town from the train station where her horses were spooked and she died from the crash.
UNKPCRIDE. doc was going to meet Clara at the train station because he wasnt there the snakes scared her horses and went over the cliff
Actually an answer to this is that Doc could have been there by himself and saved Clara for others reasons he was around and saw the horses going wild. Doc could have been looking at the train tracks in the area cause he was a scientist and wanted to do experiments who knows.
RyanKCR
Exactly, he was supposed to meet her at the station, they would have fell in love there without the the drama of doc saving her. You can tell from Clara's face when she lifts her hat back and looks at doc that it was love at first sight.
What kind of a name is Biff? Sounds like when you pop open a can of Pillsbury dough. "Biff!"
It's an old Doc from an earlier timeline that gets trapped in the past, so the only memories that that version of Doc has are the ones of Marty's actions in the first movie.
nice video, very well explained! the only explanation would be that the ripple in time didn't catch up to old doc, but that doesn't make sense given how long it was before marty went back...
There's a paradox in the first movie that no one seems to have noticed. Marty went back to 1955 and accidentally prevented his parents from meeting, which meant they wouldn't fall in love and have kids, which means Marty wouldn't exist. However, if he didn't exist, he wouldn't have gone back in time in the first place
And Marty started to disappear in the movie.
Did you actually see the movie? The whole part one was Marty trying to get them together.
I have a question about Clara Clayton on docs tombstone it says beloved by Clara but as we know she fell into the ravine. At the point they see that on the gravestone how is it there yet because Marty hasn’t gone back in time to alter the timeline to where she survives, so that means they would never of been at the tracks when she was about to go off. So doc could of never fallen in love and she wouldn’t have been on the gravestone. I am very confused.
In part 2, when Marty went to the future, there should not be another old version of him. Conceivably be would have vanished from the timeline in 1985 when he disappeared into the future and nobody would have seen him since then
If you change your own past, that past that you've created becomes the only past that you know. Back to the future messed this up.
No, you still have the same memories.
Eind actually no. You would be erased from existence and replaced with a version of you who only remembers the past that you've created.
Well, maybe so, but if not you wouldn't suddenly have a memory loss, you would remember the original timeline.
Eind though by doing so, you would've created a paradox and you would either be erased from existence or altered to fit the changes created by the paradox.
Eh, who the hell knows, no ones really traveled through time so nothing is right or wrong really.
my issue is if doc in 1955 knew he was going to die in 1885 then the doc in 1885 should know to since he is from 1985 granted 30 years have past but an event like that your not going to forget.
Yea but he didn't know how he reach there. In fact since the first movie (or the start of the 2nd) he mention 1885 so this isn't a plothole as he knew he would go there to die... Just not when
Yes. Either way, doc would have died back in the past, prior to 1955.
Just like every thing it was made up story idea.
All I have to say is "Hydrate level 4 please"
Biggest plot hole in back to the future 2 would be if Biff stole the car why in the hell would he even bring it back?
There is a theory that when one messes with time it sends a ripple through the space-time continuum that makes things change in waves. So it takes a while for the wave to arrive and things change in the future.
Yeah it's called ripple effect and basically anything you do from the past can change the future.
Anyone who dislikes this video isn’t thinking fourth dimensionally.
The part about the thing where old Doc doesn't remember his grave when he was younger actually makes sense, but the part when future Biff steals the delorean and changes the past and comes back is the one that doesn't make sense because Biff would end up back in 2015 with stuff that he changed.
This just got recommended btw
@Power106Fan true but jennifer was still in the future home after biff returned to 2015 and nothing changed when she was still in the future home but i might be wrong when i said it doesnt make sense, so when biff time travels in 1950 to give his past self the book to change the future, marty gets the book from past biff so when 2015 biff tries to go back and see what changed but its just the same 2015
@Power106Fanoh yeah, like in back to the future the game same thing happens edna time travels back in time and accidentaly changes stuff and affects 1931, even she didn't return
@Power106Fan i still dont know how that particular neighborhood didnt change
First of all, dude, he didn’t send that letter cause he needed help, he just wanted Marty to know that he was still alive.
I don't even get the first movie.I just watched back to the future 1 and the ending got to all weirded out.Marty saw himself at the mall escaping those terrorists.This means that he saw himself go back thirty years.If the marty who got back 30 years existed in the present time then that marty has got to come back again to 1985.However the evens have changed in the present time and now marty(the original one)has a luxurious life.But what about the other marty that went back in time what happens when he comes back?(I assume the 2nd marty interacted differenty back in time and thus went back to another timeline).But then doc pops out of the future and takes marty and his girlfriend with him.So if marty and his girlfriend went with doc how the fuck would they exist in the present time??
Its the same person, basically the first Marty leaving to 1955 running from the terrorists, then he is OVERLAPPING the time line with another copy of himself watching him, once he flashes back to 1955, he now is current running down to Doc, so really the change was instant, he disappeared back into the past then basically reappeared within the same minute. The way this would look to Doc who is now laying on the ground shot, is that Marty flashed back then he reappeared instantly, Just like when the dog skipped over that minute instantly arriving.
If you went back in time to when you were 15 let's say, and interacted with yourself, you would simply pass out or create a time paradox as Doc always says..., if you secretly did something to injure your younger self by setting a trap, like lets say you set a trap and a hot iron burned your younger self leaving a scar, then once you went back to your original self, you would have that scar.
Kartik Joshi You are correct. The movie, while being one of my favorite movies of all time, is also flawed. If Marty changed the past and altered the timeline, then he wouldn't be at the mall that night in 1985. He might not even be a friend of Doc's or even live in the same neighborhood. His parents are successful now, so they should be living in a nicer neighborhood. Marty shouldn't even have had to go back to the future. For once he changed the timeline in the past, he would disappear from 1955. Because he probably wouldn't have gone back in time to begin with. Why would Doc still let Marty go back in time and risk messing something up? Life is good for Marty now.
A good explanation for 2 alternate Jennifer endings
Chris Serna: Doc would make a point of finding Marty and befriending him, because he already knows that Marty befriended him, went back to 1955, helped his parents get together, etc. From Doc's POV, the first film is a Stable Time Loop.
The director said that there isn't an alternate Marty, it was just the one Marty, and, fuck that still doesn't make sense....
Why can't we .. Just for once. Enjoy an amazing film without over complicafing it. My 7 and 6 year old kids don't have a clue what's going yet they can just enjoy it for what it is.
So you're saying don't question things is that it
HERE'S YOUR ANSWER: There's tons of things that 1955 Doc sees and sees again but it never changes the outcome. Here's why: the trilogy eludes to an inherent force at play, arguably a "good" force, that's intertwined with the date Nov. 5th 1955- it's the lightening storm, the clock tower and Doc's "vision" for how time travel works. This force lets Doc become affected by many things while STILL building the time machine, etc.
Everybody says that since Biff changes his future, conseguentely the rest should have changed too, but the altered 2015 never happens and I belive that has a very simple reason: since Doc and Marty save the the timeline by changing history again, by the logic of time travel that future would have never existed in the first place: aka it was predestinated that they would save the future because nothing was changed by the actions of Biff, wich would also explain why his old self retured back into the original future and not the altered timeline.
You forgot to mention, that the 1985 Marty returns to in BTTF1 is on a different time line as the one he started in.
It does make sense. Doc sees the grave and knows that he dies in the past but since he doesn't know how he dies and doesn't try to avert it, the cycle continues. Marty goes home to 1985. Doc stays in the past and gets married and avoids dying. It's all neatly tied together. Just like the note Jennifer tried to show him. His future was rewritten.
Time to weigh in with my two cents on an old video. One point I’ve never heard anyone mention is that in 1885 there are actually 2 time machines so any spare parts and gas they need are readily available.
Wrong. Actual timeline issue: Biff would not have been able to return the Delorean to the original timeline after he stole it.
If he changes something in Ep. 1 he creates a different timeline so if he would travel back to 1985 there would be a second version of him and he would not belong in that timeline.
Marty was the one who found the grave. Without him, Doc wouldn't have even been in the graveyard in the first place. It comes down to if you think the 1955 part of the third movie actually happened in the first movie's continuity. The events that led to the 2nd and third movies were in direct response to the success of the goal of the plot of the first movie.
In the alternate past, rich Biff had Doc Brown certified, so he couldn't build the time machine, meaning he and Marty couldn't have travelled to 2015.
It's a time travel movie. If you think about any movie (where characters travel back in time) long enough, it won't make sense.
Think of timelines as parallel lines. The first films takes place on a timeline where Marty has a bad family and he ends up going to the past. Things is when he makes changes to 1955, he created new parallel timelines. Every choice you make will create parallel timelines where the choice was different. Through the film, as changes to the past are made, the characters end up in a parallel timeline. This even solves old paradoxes, why you can kill you father before he has you but then still being able to exist. It's because you are now sitting in an alternative universe where you don't exist. You are stranded there in a world that is not your own. Basically, changing the past only results in new parallel timelines. It's hard to explain but I hope someone understands what I'm saying. (Of course this is only a hypothesis)
The problem of multiple timelines and multiple copies of people in timelines is beautifully explained in an episode of Red Dwarf from Series 7 - I recommend watching it.
Good Video, however- it is missing one of the biggest errors I have noticed in BTTF 2...
When Doc comes back from the future and grabs Marty in 1985 to go to 2015 to spare Hill Valley of Marty's kid being an asshole, NO ONE has pointed out yet- that when Marty and Doc arrive at 2015 they would only get there to find out that Marty had gone missing for 30 years and didn't have any kids to speak of!
The problem with Back to the Future Part III is that there should be 2 deleoreans in 1885: the one that Doc Brown was accidentally sent to 1885 with and left for Marty in a cave to find so he could go back to 1985; Marty instead goes back to 1885 with the delorean to save Doc from Buford and ruptures the fuel tank which creates a problem for them until you realize there's another delorean that Doc MUST have since he came to 1885 with it. Marty created another paradox by going to 1885 and they should have just put the adjusted tech from Marty's version on Doc's version and headed home. The only problem with that is whether they could have added the tech before Buford was supposed to kill Doc as well as the paradox of leaving it for Marty to find in the future in the first place.
That's what i always thought, just use the other one and leave it there afterwards, it just needa to be there in 1955 so there won't be a paradox
I think a lot of this can be explained by the (admittedly wishy washy) "ripple effect".
We see in the first movie that Marty doesn't immediately cease to exist the moment Lorraine's dad hits Marty with the car and not George. By some logic, this should immediately remove Marty from existence since the opportunity for Lorraine and George to meet and fall in love has been changed. Yes, you could argue that it could still happen throughout the movie and that's why Marty's siblings (and eventually Marty himself) start to fade away gradually.
I think the fact that this "fading" establishes that the changes to the timeline aren't instantaneous then it's acceptable to think that when old Biff came back from 1955 to 2015 the world was possibly changing around him and his removal from it was part of that change. This is why I think the deleted scene of old Biff vanishing should have been kept in the movie as I always found it odd he was acting the way he was when I saw it as a child and even now it's not totally clear.
It's not perfect and I don't deny that there are holes in this theory as well but to be honest it's kind of an inherent problem with any story involving time travel.
The way I look at it is, Marty getting hit by the car is the antessident, its Potential only of disaster if,Trigger, George does not kiss Lorraine at the dance.Thats what the logic of the scene is, the t.line is starting to ' bend' , and it will buckle them break past the moment when their supposed to kiss.
My best movies ❤. I hope you are still around after 7 years ago 😊
and remember, when marty got back to 1985 in the first movie, he saw himself run from the terrorists and disappear, presumably to 1955 again. so there's some version of him in 1955 trying to get back to 1985 again.
Marty aimed always to save Doc's life in BTTF 1. Normally, Doc was killed by Lybians in 1985, but Marty gave to him a letter about his death and arrived at 5 min earlier, thus, Doc was alive in 1985. In 1885, Marty wanted to save Doc's life again because he didn't want to lose him. On the last moment, Doc changed his opinion and decided to stay in 1885. Because the timeline without DeLoreans and Doc was original timeline in 1985. In the end of, Marty came back to the original timeline, Doc visited him to say that he is ok and makes realize his dreams as a time traveler by timetrain.
