Do naked singularities also appear mathematically if the mass of a black hole is uniformly spread around its Schwarzschild surface?
I recently heard about the concept of a naked singularity and it made me raise an eyebrow. I know near to nothing to about the mathematics behind General relativity. However, I do know that mass can not move faster than the speed of light so, if mass would actually have to rotate around in the Schwarzschild sphere of the black hole, that would put a "nice" mathematical limitation on the maximal rotation of a black hole.
It's probably already thought of, but hey who knows, perhaps it might actually be interesting to look at.
