relative to this, if you do travel that fast and age slower do you actually stay in the same state of time as an observer? or would say a year to the observer be like a second to you (with whatever speed is needed).
also, id like to clear up that traveling backwards in time is impossible, my reason for this being the fact that if some1 DID invent a time capsle or whatever they could have come bak in time and told us that they invented it, and considering time is endless either the human race dies out before one can be invented or, some1 who did invent one would find a way to keep it nder wraps the entire time which does seem highly unlikely.
travelling forward in time does seem very interesting, do you know what it would do if you were instead of "moving" fast, spinning around fast?
