If velocity and acceleration are relative (IE no true fixed reference) then how come, on a spinning wheel, an ant (fixed in the wheel's frame) experiences an apparent acceleration, seemingly induced by the spinning of the external universe? This makes it appear that there is some rotational reference frame, at the very least. Perhaps there is some sort of local reference frame, based on causality being limited to the speed of light? IE, the ant on the wheel can't really spin the universe by spinning the wheel. TT TTT TTT TTT TTT TTTTTTTTTTooooooooommmmmmmm CCCCCCrrrrraaaavvveer houti!trc
