I was just reading the thread "Dark matter and black holes" started by Tanzanos and in a reply our PF Mentor, Janus, mentioned that the more mass a black hole has, the less dense it needs to be.
This reminded me of an idea I read in a book on black holes in the 1970s that as the universe contained enough mass and was of sufficient density, there was a possibility that it could actually be inside one!
Well, a lot of matter has passed through the event horizon since then so can anyone tell me if this possibility has been explored further, or if research has uncovered data that has proved it to be impossible?
