But how can we tell if a mathematical point is rotating or not? If we can't
tell, then there's no way to know if it's rotating fast enough. I don't know
much beyond this, but the fact that normal BH's can rotate (or even do rotate)
doesn't mean this "can't be enough" to form a ring singularity. I brought this
up because it seems like ring singularities would pretty useful things for
understanding more about gravity wells and possibly wormholes.
