Re: time travel real?
You wouldn't have to reset the entire universe to travel back in time. It would be a localised event. Much as, if we ever get there, FTL will not be about adjusting the universe but only a ship, so that it moves around/bypasses/cuts through conventinal space.
"Ö Times change, and so must IÖ we all change. When you think about it, we are all different people, all through our lives and thatís okay, thatís good! You've gotta keep moving, so long as you remember all the people that you used to be."
