# Are there wormholes in black holes?

##### 1 Answer

Feb 27, 2016

This is an open topic of research.

#### Explanation:

Essentially the idea is that a rotating black hole cannot collapse to a point singularity since a point cannot have angular momentum. As a result, such spinning black holes may have a flat disc shaped singularity of zero thickness, which could function as a sort of wormhole, allowing objects falling into the black hole to avoid the central point singularity and potentially traverse the wormhole.

It is not clear whether such a geometry would be stable and this is an active area of research.
