Perhaps I am red-shifted, but I just saw a video demonstrating space/time as a loaf of bread and depending on how it is "sliced" an observer would see different times across space. I am having a hard time wrapping my head around this theory. I can see how an observer from afar would see my past, and if their speed, direction and distance relative to me remain constant, they would always be time delayed by the same amount. Time would pass at same rate for both of us. My issue is the loaf theory postulates that should the observer start moving towards me they would catch up with my present and start to see my future. I think it more likely that they would observe me moving slower to the point where, as the distance closed, they would catch my present but never my future.
