I understand Einstein’s theory of relativity quite well but I keep thinking about different things and getting confused. All galaxies are moving away from us and the further away are moving faster. I know nothing can move faster than c but if there was a galaxy far enough away should it not be moving faster than the speed of light when you look from a galaxy on the other side of the universe. You couldn’t see it though because the light would never reach you. Can some one explain why they don’t move faster than c?
