Ring Singularity - Traversability and Nakedness

Traversability and Nakedness

An observer crossing the event horizon of a non-rotating (Schwarzschild) black hole cannot avoid the central singularity, which lies in the future world line of everything within the horizon. Thus one cannot avoid spaghettification by the tidal forces of the central singularity.

This is not necessarily true with a Kerr black hole. An observer falling into a Kerr black hole may be able to avoid the central singularity, by making clever use of the inner event horizon associated with this class of black hole. This makes it possible for the Kerr black hole to act as a sort of wormhole, possibly even a traversable wormhole.
