Now listen. There’s all this theoretical bullshit thrown around all the time, and so I must insist that I take it all with a grain of salt. However, since it’s all so crazy and it titillates my Nerd Glands, I also get excited by it. Is it true? Probably Not? More importantly, who cares! It’s fun to contemplate.

New Scientist:

In an analysis of the motion of particles entering a black hole, published in March, Nikodem Poplawski of Indiana University in Bloomington showed that inside each black hole there could exist another universe (Physics Letters B, DOI: 10.1016/j.physletb.2010.03.029). “Maybe the huge black holes at the centre of the Milky Way and other galaxies are bridges to different universes,” Poplawski says. If that is correct – and it’s a big “if” – there is nothing to rule out our universe itself being inside a black hole.

So yeah, it sounds like a lot of Sci-Fi wanking, but I dig it. If you want to get into the mind-bending math behind it, check out the entire article.
