Anyone read Steven Hawkings "A Brief History of Time?" Great book - I highly recommend it.
If you're not familiar with the terms "singularity" and "event horizon" pertaining to black holes, he explains it well in his book.

Here's a few quotes from PBS online:
"A singularity is a region of space-time in which gravitational forces are so strong that even general relativity, the well-proven gravitational theory of Einstein, and the best theory we have for describing the structure of the universe, breaks down there. A singularity marks a point where the curvature of space-time is infinite, or, in other words, it possesses zero volume and infinite density. General relativity demands that singularities arise under two circumstances. First, a singularity must form during the creation of a black hole. When a very massive star reaches the end of its life, its core, which was previously held up by the pressure of the nuclear fusion that was taking place, collapses and all the matter in the core gets crushed out of existence at the singularity. Second, general relativity shows that under certain reasonable assumptions, an expanding universe like ours must have begun as a singularity."
"CAN ANYTHING ESCAPE FROM A BLACK HOLE?
Black holes are usually thought of as objects with such strong gravity that nothing, not even light, can escape from them. However, Stephen Hawking has shown that black holes can radiate energy. The reason goes back to quantum mechanics and the uncertainty principle. For very brief periods of time, matter or energy can be created from “empty” space because no such thing as truly empty space exists. Hawking realized that if a particle/anti-particle pair came into existence near the event horizon of a black hole, one might fall into the hole before annihilating its anti-particle. The other particle could then escape the gravitational clutches of the black hole, appearing to an outside observer as radiation."
Another great book is "Hyperspace" and the 10 dimensions.
