Quote from ZZZzzzzzzz:
Is it a fact that the earth revolved around the sun?
It's a fact, to the current way of thinking, that objects and space are one entity, and that their relationship is relative. If we decide to definitionally fix Earth in a static location in the universe, we can do that, and then everything else can be "observed" moving around it, albeit in a most complicated, non-intuitive way.
