> If the ship were not moving relative to the earth which was moving as a constant velocity away from the ship at near the speed of light If the ship is not moving relative to the Earth, then the earth is not moving relative to the ship. The trouble I have with your first explanation is that the ship and Earth are moving away from each other -- it's not like one is the stationary one -- it can't be true that one experiences time more slowly, in some absolute sense, than the other. Whatever phenomenom happens to video streaming should happen in either direction.
