   I came across these on the arxiv blog, thought it was kind of interesting, although utterly disconnected from reality:

   Interesting indeed.
   As for their disconnection to reality, i say it's not "utter".

   Hmm, I need to read those before I call "reality" or not, but... they look incredibly fun at least. Thank you bcrowell, that was very thoughtful!

   Solutions of the EFE in more than 4 dimensions seems to be a hot game. These score high on the exotic scale. I liked the taxonomy of black holes.
