Where is the way on a rotating black hole to another Universe? Where and how should it be entered by to get away from here?

  • $\begingroup$ Who says there is another universe that we can get to? $\endgroup$

    $\begingroup$ This question appears to be off-topic because it is about speculative physics and requires an in-depth explanation of the Kerr metric which makes it partially too broad and partially non-mainstream. $\endgroup$ Commented May 16, 2014 at 19:46

    $\begingroup$ @Brandon Enright : While I agree that to answer this question would be pure speculation, I absolutely disagree that the Kerr Metric is non-mainstream. It is a well studied solution to the Einstein equations which is to be found in any graduate lecture course on Black Hole Mechanics. See Cambridge for example. $\endgroup$

1 Answer 1


The singularity in the Kerr-BH has the form of a ring. This ring is in the event horizon, although if the BH rotates enough fast, it could be out of it, which were nonsense.

Some interesting happens if you are going through this ring.
