Time travel
Posts  1 - 2  of  2
Well, I'm not really well educated in this kind of thing, but I'd really like to learn. That being said, I have a couple of questions that I hope somebody can answer.

1. Assuming that parallel universes can indeed be reached, what would one call a person that is the exact copy of someone else, except from a different universe? Would it be a parallel doppelganger, I'm just not quite sure what the official term would be.

2. If somebody were to change the past, hypothetically of course, then one could argue that a universe would diverge where it did change the past, and one where it didn't, because that would create a time paradox. However, if in the universe where it didn't work, would time just stop for that universe? If something were to change that would change that universe, then it would have to just stop to avoid changing, right?

Maybe I am completely off base with these questions, but like I said, I am new to this, so any help or answers would be appreciated.

Try looking at the discussion on the thread:
"Is time travel possible?"

There're some points worth noting.
