WE COULD be living inside a black hole. This head-spinning idea is one cosmologist's conclusion based on a modification of Einstein's equations of general relativity that changes our picture of what happens at the core of a black hole.
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.
In Einstein's general relativity (GR), the insides of black holes are "singularities" - regions where the density of matter reaches infinity. Whether the singularity is an actual point of infinite density or just a mathematical inadequacy of GR is unclear, as the equations of GR break down inside black holes. Either way, the modified version of Einstein's equations used by Poplawski does away with the singularity altogether.

Let there be light?
Well, that is entirely possible as well, but not where I was going exactly.
I was referring to the Big Bang and Singularity theory.
IF true our Universe started as a single point, which expanded to form the current known Universe and is still expanding (according to 'science'), then it is possible it emerges as that Singularity from a black hole , which was part of a 'different' Universe.
The problem for me is I don't accept the multiple Universes theory to begin with.
But were it possible, I could see how each black hole could be the pathway to another Universe, and how each black hole contributes to building another universe. However, much of that 'understanding' is based on our limited perception abilities and limited understanding of our Universe, especially that little thing we call gravity.
>>I was referring to the Big Bang
So was I.
One instant there was nothing - the next, all the energy (and mass) in the universe existed.
Not a bad guess for a bunch of nomadic sheep herders, ehh?
