“I mean, what’s the point of reference? Isn’t that the pertinent fact? Why can’t we consider the Earth fixed and all of creation “orbiting” our planet, more or less?”
According to relativity, there is no universal frame of reference. You can pick whatever frame of reference is convenient for your purposes, as long as you are consistent.
So it’s no more correct to say that the earth revolves around the sun than it is to say the sun revolves around the earth. Either one can be true, depending on the frame of reference you choose.
My point exactly.
Ate you saying that planet Earth identifies as the center of the universe?
