: : This is a strange question so please bear with it...

: : If there were several, say 3, black holes all on the same plane and in orbit around a central point that lay just inside the event horizons of all the black holes in this scenario so that there was an area that lay inside all of the black holes simultaneously, then what might be the properties of that region of space? Would it be possible to send something through the gap and out the other side without it falling into any of the gravity wells?

: : If you mean that the 3 black holes orbit around : a central point that lay just OUTside the event : horizons, then yes.

: If you mean that the 3 black holes orbit around : a central point that lay just INside the event : horizons, then NO.

: Infact if the latter was true then there would : be quite a bit of overlaping Event Horison (EH) : and the 3 Black Holes (BH's)would likely merge : into 1.

: : Here is another interesting question. Is it : possible for the 3 BH's to be rotating so fast : around this point that their centrifugual force : kept them apart even if their EH's overlaped?


I'm not sure about 3 objects. I don't believe 3 objects rotating around a single point is a stable configuration. Binary systems are very common, but has anyone ever heard of a trinary system?

In the case of 2 BH's rotating around a common point, they would have to be very close in order to overlap since BH's are very compact. Beyond that, I can't guess as to what would happen.
