Because of the speed of light, and the distance between us and certain supernovas, we're just seeing the light of it, even though it occurred 170,000 years ago.
If we were able to travel twice the speed of light, I know it's impossible, but what if it were, and someone traveled to a planet a light year away, and then returned. Would, in one light year, we be able to see that person returning to earth, and would those same images follow the life he led up to his death?
