Loop hole in the BTTF universe? *SPOILERS*
OK, so by Emmet not going to the movie and hooking up with Edna, And then when Marty and Doc go back, Doc disappears while they're in the car. When Marty arrives in the alternate 1985, my question is, if that doc didn't exist, and the new one never invented the time machine, hence all the things they changed in 1955 never happened, meaning Doc never built the time machine, then why didn't the time machine disappear as well? Also, why didn't Marty disappear as well? I mean, in BTTF2 they explained that while time changed, since they were in the time machine, the time stream changed around them, but then wouldn't Doc not disappear?? Just seems like a loop hole. Unless Doc did build a time machine in secret without Edna knowing. But even then, if the events in 1955 were never changed, and the time machine was never built then it would also effect the changes made in 1885 and 1931. Unless someone wants to explain this to me. But I don't think Doc Should have disappeared.

*Because he never would have gotten the life-extending rejuvenation in the future, and because this Doc is several years older than the Citizen Brown Doc, Doc in this new timeline wouldn't live long enough to be as old as he is, so he can't exist... Yes, neither can the time machine, but I think what happens is that no matter how much you screw up the timeline, the changes affect time travelers themselves more slowly, and it seems the changes will always impact the time machine itself last, if ever.
I'd rather just enjoy the game/movies. If I pick on every single little thing, it would never end. You are right, Hituro, totally right! I just prefer to tone down the "Logic"-dial just a bit when playing this series. It's much more fun that way.
The time stream doesn't catch up to Marty as quickly because Marty has only time traveled for weeks rather than years like Doc and Einstein, so he is still the correct age in 1986. The DeLorean still exists because time is still being written, as explained at the end of Back to the Future Part III. Doc exists in 1986 as Citizen Brown, so the DeLorean still has a chance of being invented. (It's like why the photo didn't disappear at the end of Back to the Future Part III even though it just showed grass. Time was still being written, since Doc would have to put up the tombstone showing his death after Marty got back to 1985 in order to prevent a paradox).
Omg you're right, I totally forgot that even though Doc is with Marty, he's much much older than the Doc of 1986 due to the excessive time travel. Plus who's to say Edna doesn't bump off Doc at some point in Doc's future. And also, that makes sense about the Delorean. It's almost like the car is the photo of the grass, rather than the objects in it. Also I remember in Back to the Future II, when Marty went back to alternate 1985, he didn't erase, and his clone was off in Switzerland. So yes, you're right, it makes sense now. Thanks for clearing that up!
thats just a movie gimic, yes there should have been a different grave there but it would confuse the audience if there was the name of a character they didnt know there and if it was one of the existing characters that they were saying was buried there instead it wouldnt rule out that doc might have just been buried somewhere else.
Well actually we don't know if theres another marty in swizerland and another doc in a mental institution, it is never stated nor denied.
Doc is at least 15 years older than he should be (his children are already to go to college) and we have no clue how long he was time traveling prior to bringing Marty to the future.
Did you know that time travel is not possible? THIS GAME IS INVALID!
Doc doesnt know what happens if a paradox occurs so he acts precautious to prevent one but maybe they already have happened and can exist; ie. part II should be a paradox because the future was fixed giving doc no reason to bring marty there and at least 2 timelines do not have time travel being invented (the biffhoric timeline and FCB)
The third and fourth scenarios are definitely paradoxes by normal standards, but they are able to exist in the Back to the Future universe by that universe's rules of time travel, since the time ripples haven't caught up to Marty and the DeLorean yet.
I'd personally love to see a paradox like Sliders or Futurama (where the paradox rips open a tear in the universe), but by this universe's rules of time travel, that would require a major paradox to occur (like the time machine ceasing to exist or forgetting to prevent a circular paradox) since this universe's rules are pretty paradox-proof.
pretty much any time the characters time travel intentionally to change the timeline (doc bringing marty to the future, biff stealing the delorean, doc and marty going back to 1955, marty going to 1931 to save doc and further back to save his grandfather and again to get kid arrested), that should create a paradox. So maybe the rules are the timeline simply continues linear in the event of a paradox. So for instance in the 2 timelines without any time travel all of a sudden marty disappears from wherever he is and appears in a delorean.
Or had marty been unsuccessful in getting his parents back together in part I, he'd fade out and the timeline would simply show a mysterious figure named marty show up for a week in 1955 and fade out. Though in this case, i'm sure what would happen is as soon as doc got his hands on plutonium, he'd go back to that day, and bring marty back to 1985 before he got a chance to mess with the timeline.
How come the delorean still exists when doc never invented it in the new timeline.
How come doc disappeared when they went back to 1986.
How come Marty didnt disappear when in the new timeline he is a nerd (stiff).
The DeLorean and all of its components still exist in this timeline, even if Doc didn't put them together. Maybe it will fade out over time, maybe not.
Doc is almost 100 years old. In the FCB timeline, he doesn't live that long.
Same reason he doesn't disappear when he's supposed to be in Switzerland in BTTF2.
The fact that no one's been able to time travel YET doesn't mean it can't be done
Well if it ever does, we will never know about it in our life times. Actually when I was 7, I wrote a note to myself with a specific date and time to travel back too. And then locked it up and put it in a little safe i had. I waited, and when the date came my "future self" didn't show up. I was so disappointed that I ripped up the note and threw it away. I do not remember the year, date, time or anything of what I had wrote down...21 years later, still no time travel. Now, did I correct the paradox or did by ripping up the time traveling request (time capsule) did I prevent myself from visiting myself during childhood?
(i was a huge BTTF fan as a kid).
But I suppose it's a possible theory at this point, since I believe so far the time ripple effect was never mentioned in the movies or the games.
It would be weird to wrap your head around it though, since there would be a Marty without Marty being born. Although other fiction has done similar things with an object being given to a person in the past that came from that same person in the future, which would mean the object was a subject of a paradox since it never came from a specific place in time.
It's perplexing. Would the timeline correct itself and erase Marty from 1955 in the past, or would he still be there in the past since someone had to intervene to get George to stand up to Biff. The ripple effect suggests the former, but in order for the timeline to progress linearly it would need the latter. Even more perplexing is your second example. If the timeline did keep Marty in the past, could Doc stop Marty from going to 1955 and still continue linearly from the changes made in 1955? :eek:
If anything, if the universe is self-correcting and a paradox doesn't cause disastrous consequences, I imagine that if Marty or Doc created such a large paradox, the universe would just reset itself to how it all happened before they traveled through that particular time period and create a time bubble where Marty and/or Doc leave but never reach their destination (although a universe with disastrous consequences is much more fun than a self correcting one any day
It will start fading out next episode. Which would explain Marty's panic. Because he deviated the timeline further away from where Doc built it.
If close enough timelines can and will merge. We've seen that.
