Black holes are points within space whose mass is so large and whose gravitational force is so strong, that they attract everything around them and once within their range of attraction, nothing can escape including light, because the escape velocity necessary to escape is infinite. There are many theories for why black holes exist, but Einstein's is most likely the most famous theory of black holes.

Einstein's theory was that the space time continuum was a flat plane of existence with masses representing indents within the flat plane. However, a black hole does not represent an indent, but a puncture within a space-time continuum, giving a representation of infinite gravity.Stephen Hawking gives a good lecture on how black holes work.

Within the video, Stephen Hawking references the infinite gravity of the black hole, and the idea that particles can escape. The difference within these particles and its ability to escape is because only one particle passes the singularity, or the point of no return, while the other particle has enough momentum and velocity in order to escape the black hole and be emitted as a form of radiation.

Hawking also touches briefly on falling within to a black hole and encountering a new universe. This references the theory within quantum physics that there are an infinite amount of universes parallel to ours in both minute ways and large ways as well, depending on the decisions that we take. There is no clear answer about where black holes lead to, but one theory is that, if one was able to survive the journey, which is very low to none, it would take the observer to a new universe separate from our own, ejecting them from what is known as a "white hole."
