(Or contracting, but that no longer seems to be a possibility for us). Then you'd need the planets, the stars, the galaxies, even gravity itself to stop moving. Every single thing in our universe is moving according to the point of view of something else. And every single thing can use itself as an observation post which it can itself say isn't moving.If I get on rocket ship to the Moon and reach the vacuum of space where I then shut down my rocket, I can say that the rocket is moving through the vacuum towards the moon. But I would be equally correct in saying that the Moon is moving through the vacuum towards me, and that my rocket is standing still and merely waiting for the Moon to reach it.That's like saying "let's forget about the laws of physics as we know them, so that we can discuss the laws of physics as we know them". The way you see things by way of light is an intrinsic part of the question of what you would actually see.</blockquote>
