It may well seem ridiculous to imagine the entire universe moving to and fro in relationship to ourselves while we stand still, but it cannot be demontrated mathematically that this is not the case.
On the other hand, it is certainly satisfactory to the mind to imagine the universe standing still and ourselves moving, so that's the way we see it.
It's all relative. Neither perspective is absurd.
It's not all relative. Educate yourself. With all due respect and without malice, I can't be bothered explaining the obvious to someone who chooses ignorance or, as it is better known, subjectivism, as a path.
