travelling faster than light doesn't move you back in time, time just moves more slowly for you than it does for the outside world.
before worrying about such things we'd need to become more radiation proof as a species or learn better shielding techniques though. astronauts tend to die younger and have a bad habit of getting cataracts among other things from their brief time in space.

Well did something exist before the big bang. Even if it was just nothing. I mean it would be all black because there is no nothing but is there something. You sure about things just moving more slowly if you go faster than light? I think it is a big FU to physics so there are no laws for that because physics say you can't go faster than light. Aren't there some things in the universe moving faster away from us than the speed of light so we would never be able to see thm as the light is not comming fast enough for it to ever reach us?
Was there a universe before this one? They say the stars are moving away from eachother and never will come back to together like they once thought. Now, will the entire universe be spread way to thin and everything just die out? Then WHAT!?! THEN WHAT?!!? I think we should start preparing now.
like i said this is cake. Question three is what we should focus our attention to.
