:surprisedOk, without criticism can we all just accept for argument sake a newtonian spacetime? That is - without relativity. Ok, i'm going to try to describe something that I thought of a long time ago (considering time travel when I knew not of relativity). If information travels through light, what things would happen if we travel faster than light? Will you be not seen by others while you are passing them? And they only see you after you have passed them?
