> they're saying that you cannot prove that the earth is moving. again, you're misunderstanding what's being said. what is being said is you cannot do any experiment in physics to determine objective movement when there's relative motion between two inertial frames of references. you cannot determine absolute motion in the absence of acceleration. > this makes perfect sense if the earth is the center of mass of the universe this wouldn't even be a necessary assumption. you can construct a geocentric model where the center of mass would be moving around the earth. regardless > everything is revolving around it again is something that only works under the guise that everything has to orbit other things too: > the sun orbits earth > mercury orbits the sun which orbits the earth > europa orbits jupiter which orbits the sun which orbits the earth is the only way to make geocentrism work. geocentrism only works when you accept that every inertial frame of reference is equal, and then on an emotional basis proposing that earth is "more equal".
