THere was something on TV that seemed to imply that the farther the distance is between two objects moving relative to each other, the greater difference in the perception of what everything was "at that instant" would be. It didn't seem to be talking about seeing/perceiving things at the speed of light. It had something to do with future, past, and present all existing for everyone.
But I don't see why distance would increase this effect.
Point is, light does not travel instantly. The farther away two things are, the longer it takes for light to get from one to the other and back.
