QUOTE (warita200 @ Apr 13 2011, 06:47 AM) 1) if the time traveler decided to remain in this altered past, then there is no problem, right??? But what if he wants to return to the future?
2) Can he go back to the world number one with the unaltered future? That would mean not only time travel, but also travel from one parallel world to another.
3) or is he trapped in the parallel world he created, meaning he can travel to future, but it isnt the future he came from, aka nobody knows him, etc?
But to come back to John Titor story. He claimed he traveled back to the past to prevent the third world war. But by doing so, he would create a new parallel world and if traveling between the worlds is not possible, then that would effectively trap him in this world. That means his plan to acquire the PC model and return to the future to use it is logical faulty, because it is likely nobody in this new version of the future needs the device or expects him to return.
Also, I am also hoping whoever John Titor is reading the books and articles written about him and I bet he is laughing his ass off, watching how this whole fooling around in the forums created a hype around him and he even appears in animes and so on. I really liked the references to him in this anime and I am looking forward to the next episode greatly.
1) Theoretically he can't. IF one is succesfully creates paralel timeline and/or transfers into one, he should by all means become part of that timeline.
If he moved into future from that point he would move into future of that timeline, possibly causing it to split yet again at the arrival. The only way to even do that would be arriving at at least SOMEWHAT identical parallel timeline, which according to chaos theory is...well....good luck trying.
2) Theoretically all time travel that is plausible is a travel between parallel universes. And no. at best he could through his actions create/jump into a similar parallel world to his own, but due to application of butterfly effect, there's no way for him to know the extent of divergences his choices make. He could, for example, bump into random person in america in the past and that would diverge the timeline into another parallel where, for example, USA is governed by nazi totalitarian regime in 2011.
3) He can travel through the current parallel universe or he can change something else, making it shift into yet another parallel universe. To be exact, from traveler's POV, the universe he IS in is the primer/primary universe, while the one he WAS in becomes a parallel from his POV.
Traveling in time = Traveling between parallel realities. AT our current understanding of quantum physics, it is nigh impossible, because to cross over to another parallel you need to be "disassembled" at molecular level and then reassembled a the parallel. What happens with that? Look at the banana going gel banana in the episode.
That can be. But time travel point is not to "change" parallel universes. Its to change the primer universe from the traveler's POV. So if he ends up in timeline where no one needs that, its all good for him anyway. Thats what is depressing about multiple worlds or multiverse - there's a world where any of is us dead, there's a world where we did not just think about that and so on. And nothing can change that.
Possibly. But that is one things we will never find out. And even if he was a fake, there's infinity of parallel realities where he was not a fake.
