Can someone explain to me how do you tell which twin ages more quickly if you can't tell which is actually moving closer to the speed of light? Isn't it possible that the Earth is moving through the universe at a high speed so the spaceship is really at rest, in which case woudn't the spaceship twin age more quickly?
