This is because he was killed a some point before 2015, whereas he still existed in the previous timeline. The classic Back to the Future rules of time travel say that whatever you change in the past can have huge effects on the future.
Back to the Future writer Bob Gale on the rules of time travel and Avengers: Endgame. Maybe it was just a simple heart attack. The correct response is "So everything doesn't happen at once!" You can't stop Pearl Harbor. Each timeline does “exist”—we see them both in the movie. The iron atoms were probably in some magnetite iron ore on a mountainside at that time. We like to think of time machines as capable of traveling the fourth dimension. This “reset,” however, takes time (as evidenced by Marty slowly being erased from existence in Part 1), suggesting that the time travelers have a chance to “repair” the altered fabric before it resets.Following this thinking, if Marty and Doc had taken too long to retrieve the almanac from young Biff, their memories would have reset to the new “healed” timeline (where Marty is Biff’s stepson and Doc has been committed).
we can assume that they have areas of greater and lesser resistance. According to experiments using a quantum time travel simulator, reality is more or less “self-healing,” so changes made to the past won’t drastically alter the future you came from – at least, in the quantum realm.But which set of rules has more basis in science? I only hope that none of my tax money paid for this experiemnt.Maybe there are five extended dimensions, length, width, height, time, and probability. And this one is a bit more esoteric, but if you’ve heard of an old video game called Shadow of Destiny, it’s an excellent example of tapestry timeline theory.Get email-only exclusives from Overthinking It right in your inbox.I’m very curious about the moment when Old Biff returns to 2015 after dropping off the Almanac. Also, in this theory you would disappear for the intervening years, meaning that Marty would never find himself or his family in 2015…Unfortunately, none of the BTTF movies offer a satisfying storyline with only “N-jump” non-paradoxical explanations. At some point in the past, Bob interferes with the qubit by measuring it. With a Bachelor of Arts in Professional Writing and several years experience under his belt, he joined New Atlas as a staff writer in 2016. If you return, nothing will have changed for you. "The Hill Valley we come back to at the end is pretty much the same. up the timeline the world is programmed to correct itself. We don’t follow old Biff’s story once he returns to the future, but his plan could have already failed, assuming the predestined timeline prevails.That's just bad compositing. Since we can’t exactly jump into a TARDIS and start experimenting ourselves, researchers at Los Alamos National Laboratory used a quantum computer to develop a “On a quantum computer, there is no problem simulating opposite-in-time evolution, or simulating running a process backwards into the past,” says Nikolai Sinitsyn, co-author of the study. Eddies in the space-time continuum. When Biff alters the timeline he creates a split that leads into an alternate timeline via 5th dimensional space. When MARTY travels back in time in Part 1 and changes the future, and then goes back to the future, things are different.Short answer: Biff HAD to come back to the same 2015, because otherwise Marty and Doc would have lost their time machine and the movie would have ended.For a more “realistic” depiction of how time travel might work, check out the movie “Primer.”I think the explanation of Biff’s return to 2015 was that it was a different reality than the one he left. According to a new study, quantum mechanics supports the In a way, it all comes down to the butterfly effect, where a tiny action in one system can escalate into huge consequences. In addition to hosts Joe and Anthony Russo, the hour-long conversation also featured the Marvel scribes behind Both Markus and Joe touched on how Marty's adventure in 1955 is permanently fixed into our pop culture consciousness.
