if all motion is relative, how do we know the Earth isn’t stationary with everything else in the Universe rotating around us, albeit in a right weird and in uniform way.

if all motion is relative, how do we know the Earth isn’t stationary with everything else in the Universe rotating around us, albeit in a right weird and in uniform way.

Answer 1

Even if you thought of the Earth as stationary, the other stuff isn’t rotating around around us. Imagine a car stalled on the highway. Some stuff is heading away from it. Some stuff is heading toward it. Nothing could be perceiving as rotating or orbiting around it. It’s the same for our position in the universe.
