I seem remember somewhere there was a thread last year to discuss about what happens inside a rotating cylinder. It's to say if the obsever inside a rotating cylinder(big enough) can find out the motion state of the rotating cyclinder by experiments inside it.
I would rather say no, just like the observer inside the accelerating cabin cannot find if the cabin is accelerating or in a gravitation field. This is what the Equivalent Principle say. Now I find it's really very important to talk about this question as it deals with an Equivalent Principle between spin and magnetism.
Could anyone give me the link to this former thread?(I could hardly remember if I found it somewhere else)
Thanks
