time travel.

i also think if it is going to work it would have to be along the theory of spacial displacement. where a space from one place is swapped with the space of another.

What about potential differences in momentum ?

i don't think that would matter so much because it would be relative to where you start or end up.

imagine all the different time lines. looked at from any angle (theoretically speaking) it would only look like there was one. in fact there could be an infinite number occupying the same space.

energy and mass in the universe is a constant. maybe it's same with time.
