I guess I wasn't clear. When I said empty space, I meant E M P T Y. Nothing there but you and empty. No starts, gravity, atoms, radiation. Nothing.
The point is that if you have no frame of reference are you really spinning? It's a corollary to the constant velocity question. As much as you expect that you'd experience centripetal force, that presupposes you can spin in a universe with no frame of reference. The question is, can you if you are spinning there are you really spinning? Can you spin?
That was my question for 1984 and being stoned.
