If I understand what I skimmed, the idea is that space-time itself rotates, not all the collective matter in it?

- jfengel 2y agoCorrect. Though the matter in it would also move, dragged along by the space-time. It's much like the expansion of the universe, which is separate from the ordinary momentum of the objects within the universe. But the objects within the universe do move apart along with it.
- BurningFrog 2y agoThanks. These things really challenge my physics intuition!
