May 20, 2014 at 7:37 comment added user10851 @AlanSE I just wrote up a somewhat lengthy review of toroidal horizons related to this question: physics.stackexchange.com/q/92224. I don't know if you've already read those papers, but they show many ways you can't have tori, including topological (not cosmic) censorship.

Sep 27, 2013 at 20:56 comment added Alan Rominger @ChrisWhite That is helpful, I had not seen it. Still, they do ask about transient torus BHs, while I'm looking for the argument against stable torus BH. I might have titled this question too specifically actually. I'm really shooting in the dark about the censorship theorem.
Sep 27, 2013 at 20:46 comment added Zo the Relativist And I should say that it is very definitely the case that you can build a time machine out of a Kerr naked singularity by travelling a closed path that goes through the ring. I don't necessarily see why this should generically be true for all toroidal black hole horizons, but I remember my advisor saying that known numerical solutions that included toroidal horizons quickly evolved to spherical black holes.
Sep 27, 2013 at 20:43 comment added Zo the Relativist You shouldn't say "cosmic censorship theorem." The result isn't proved. And in fact, over a precisely fine-tuned subset of normal matter distributions, cosmic censorship will be violated.

Sep 27, 2013 at 20:00 comment added user23660 Is this somehow connected with black rings solutions in higher-dimensional gravity?
