This isn't a new story, but I just happened to stumble upon it today, and find it extremely fascinating, the idea that black holes contain universes, sort of like a portal linking the macro and the micro, that within each black hole there is an entirely different universe, and I suppose an entirely different dimension of reality, perhaps resonating at higher and lower octaves, that of heaven and hell, and all that.
It's pretty extreme, to me, more in the realm of religion than science, because probably the more you learn about it, the more you realize just how infinitely mysterious it all is and will always be. I believe there is so much more going on in the background of the universe, the hows and the whys, the underlying meaning and order of it all, that is just way beyond the threshold of human understanding.

Are We Living in a Black Hole?
Our universe may reside within a vast, black hole.
