> If the moon orbited earth a little bit faster, would the number of microseconds per day accumulated change (even if ever so slightly)? Meaning, if you attached rockets to the Moon to speed it up while not changing its orbital radius? In that case the speedup relative to Earth clocks would be less, yes. > in principle, I should be able to come up with a thought experiment that highlights what that speed means I gave you one upthread, in the subthread where the movie Interstellar was being discussed. > Would this hypothetical faster moon, billions of years orbiting earth at a different speed, look geologically younger than our regular speed moon? Meaning, if you compared the two after billions of years of Earth clock time had elapsed? Yes.
