Still, though, you'd have to have a pretty good system for mapping out the universe if you wanted to know where the hell you were after the time travel.FuSoYa said:Sam I think what I've read about time travel is that the only way it'd be possible would be to create a gravitational force so strong that you would twist space-time so that two points existed in the same space. I think the implication was that it would really only be possible IN space, outside of the earth's atmosphere anyway.

Well that's kind of my point...has science established an absolute coordinate system for space? Or are all movements simply measured relative to larger bodies?xfer said:well, it depends on your point of reference--at what point, exactly, do you have to map out the universe moving? better to try to tie the time travelling to a fixed point, like the center of the earth, or something, right?
