So far i understand that a star many light years away from us can be moving at the speed of light, but this breaks no rules as it is traveling with space.
But how about the star's momentum relative to us on Earth, i can only guess as it is moving away from us at the speed of light it's momentum would be the same as a star actually traveling through space.
But then that sounds strange, as the universe would be gaining energy as it gets older
Thank you, old ned.
