"Rotating frames of reference are not inertial. Therefore, you're incorrect. If the Earth didn't rotate, the coriolis effect wouldn't occur, for starters."

It could still occur if the coriolis effect is in fact caused by an entity different from the entity to which we ascribe its causation.

In other words, when you said that a universe in which the Earth is fixed would be indistinguishable from our own, what you meant to say was that "a universe in which the Earth is fixed, and all the laws of physics are changed to make that universe indistinguishable from our own," would be indistinguishable from our own?"

Well, okay. Who cares?
