Re: [Phys-l] Absolute four-momentum of massless particles

Bryan Whatcott comments:

I should be grateful for some commentary on the proposition that you CAN
determine absolute axis of rotation by experimental means.

My initial reaction is that rotation is not inertial, so you can do experiments to characterize it without violating provisions of SR. If I'm oversimplifying, perhaps I don't understand your question.
