Kerr metric and black holes

A different explanation I told someone in a comment to their Google+ post, wherein they mulled how it works.

This is what my tired mind conjured up based on skimming the Wikipedia article on the subject: The Kerr metric suggests two surfaces with singularities: a round one inside an oblate (elliptical one). Imagine putting an empty toilet roll into the hole of another, and then rolling one clockwise, and another counter-clockwise. I imagine, a Kerr wormhole is a hole, where one hole is in another, and leading from a certain point A to a certain point B in the universe.

Now, the image at Wikipedia suggests (to prove?) multiple-universe theory, in that unlike the Schwarzschild black whole, where the orbit is confined to a single plane (if wormhole, then travel from point A to point B), then the orbits around a Kerr black whole are filled in a torus-like region around the equator [of the black hole].

In conslusion, the image supports a multiple-universe theory; so not just from point A to point B, but presented with some choice. OR, an unstable, but traversable wormhole.

I don't really have anything else to back this up with, but the musings of my rather vivid imagination.
