well according to conventional physics travelling 500 light years in a number of days is impossible!! i suppose it never stopped us before.

at light speed it would take you 500 years to reach said star.
to reach it in a few days would require faster than light travel (which i've read isn't strictly impossible due to the expansion of the universe, though i could be wrong).

time slows down the faster through you go in space. according to special relativity the combined speed of any object’s motion through space and it’s motion though time is always precisely equal to the speed of light, so the faster you go through space the slower you go through time.

i suppose if special relativity is at least partly right (and wrong in the sense that you can travel faster than light) then the faster you go, beyond light speed, then time goes backwards or you travel through time....??? but if it goes backwards then after a while youll just end up not arriving at your destination at all only back in time before you set off...

quite strange

i not sure from where, but a theory in quantum physics states that time overlaps itself and everything is happening all at once. if everything is happening at once, then you can be at all places at all times. traveling a distance is irrelivant then.
