Suppose that angular momentum of mass M is equivalent to the angular momentum of the background universe spinning in the opposite direction from center of mass M. Suppose that the background's true rotation is un-observable. What would be the implications of such a supposition?

If you suppose that X is unobservable then by definition it has no observable implications.
 
X's rotation is unobservable. You can't see it spinning. Maybe you can figure out that it is in other ways.
 
Yes. It is observable but indirectly. What I mean by "unobservable" is that you cannot see it spinning because it is the background and therefore there is no reference by which to gauge its rotation.

You don't need a reference to gauge rotation. Rotation is non inertial motion so it is not relative.
 
In this supposition. I'd like you to suppose that it is relative and see what the implications are.
 
Please PM me with a peer reviewed reference that describes this scenario. I will then reopen the thread for discussion of that paper.
