Quote:Originally posted by Finn mac Cumhal: Can you go back in time and see yourself? On one hand, that is precisely what one would expect, but since you’re you how are seeing yourself as someone else when you’re not someone else, but you?

Quote:Originally posted by chrisisall: The mistake here is the "We" go thru time, as if we're swimming down a river or driving down a road. We exist in all moments, like a googleplex of slices of time that you pick from, and yet we are unique in any one of them, so when Marty saw himself in 1955, it was the self of THOSE moments- the soul exists thru all of them...across time itself.

Quote:Originally posted by Finn mac Cumhal: An electron can travel back in time, because an electron is not unique. It can’t be distinguished from any other electron, nor can it be even exactly specified in space. So we don’t know where an electron is, nor do we know whether it is different from any other electron. As long as you are you, you cannot go back in time.

Quote:Originally posted by chrisisall: Not so much that it disregarded paradoxes- I got that they were part of what had always happened- I disliked it because the last 20 minutes turned into a bad remake of the last 20 minutes of Army Of Darkness (a glorious film, that!).

Quote:Originally posted by Finn mac Cumhal: He explains that the crew wasn’t being sent back in time, which is impossible, but copies of themselves are sent into an alternative universe the act of sending a copy of a person into this alternative timeframe entangles the two universes so that any influence the copies have in the alternate universe is represented by alternate copies of you in your universe.

Quote:Originally posted by DTuck: The way time travel is usually presented with respect to the multiverse theory, is that, you would be affecting a universe infinitesimally different from your own, and following suit, the 'you' from another infinitesimally different universe would be affecting yours. So: While you are not changing your universe's past directly, there is another you, essentially the same in every respect, who is affecting your universe's past.

Quote:Originally posted by DTuck: a quantum particle's difference caused a tangent universe where everything else is the same, and the 'you' of that universe goes down the same path, entering your universe in the past and affecting it in exactly the same way that you affect the past of the universe that you travel into.

How do you influences events in history if you’re not even in your own history? If you go back in time in some other universe and kill Hitler, then you can’t expect that Hitler would have been killed when you return to your time. In fact, wouldn’t you return to a completely unchanged timeline?

Quote:Originally posted by Grounded: Indeed. But take the Twelve Monkeys example where Cole travels back within his own history. The 'side-step' in this instance is that he ends up in causal loop, as evidenced by the fact that as a child he remembers seeing his future self die. The fact that the two Coles see each other doesn't produce a paradox (there may be other paradoxes in the movie, I can't remember!), because young Cole saw himself 'the first time around'. I use quotes because in the causal loop scenario there is no 'first time around'! I guess the vague point I'm trying to make is that most fiction tends to go with a concept of time travel that produces paradoxes by the bundle i.e. a supposedly mutable timeline that can be dipped in and out of at will. Those that implement many worlds or causal loops are few and far between.

Quote:Originally posted by Finn mac Cumhal: Also I want to clear up a distinction, when you say that it “doesn’t produce a paradox” I’m not sure that’s true. The paradox is probably there, it’s just being ignored.

Quote:Originally posted by Grounded: It seemed to me that you were arguing from a philosophical perspective (i.e. if I'm me looking at myself, which one am I?), but from a physical perspective I don't see the issue. Of course, I could very well be missing something obvious - it's hard to keep track of all these pesky time travelers... ;)

That doesn’t really make a lot of sense.

Quote:Originally posted by Grounded: But what I'm saying is you're talking about a philosophical 'you' by equating the 'you' of now to the 'you' of then. In the Twelve Monkeys case, what percentage, if any, of the particles making up young Cole's body are the same as those making up old Cole's body? And would it even matter if there was duplication between the two?

Quote:Originally posted by Finn mac Cumhal: If a person at time A travels (somehow) back in time and meets his younger self at time B, the problem that emerges concerns the nature of predetermination of time. If B recognizes A, then the system is overstrained, because the person at time B must return to B at A. But the older self knew the events that took place at time B, and so the younger person must not diverge from those known events, since it would constitute two different timelines at odds. Time is therefore predetermined, but if that is true then we should be able to determine the exact position and velocity of a particle, which means that quantum mechanics is wrong and we can now say that the two particles are unique.
