Rotating micro-geons

When m > a there is no naked singularity, neglect charge e for now.

The angular momentum is an "area" in Planck units. Essentially it scales as G, so does m.

Therefore the parameter a is invariant under the rescaling of G.

Hence it is easy to hide the ring singularity behind an event horizon in the rotating micro-geon as G increases.
