Black holes have transfixed scientists since they were first theorized. They have been the subject or part of numerous science fiction books as well as legitimate scientific work. Albert Einstein included them in his many papers and there is one at the center of every galaxy. There are hundreds of fascinating facts to be had about black holes, but it can take quite a bit of time trying to follow a hodge-podge of links to track them down. Here on Universe Today, we wanted to cut down on that time for you, so we assembled many of those facts into different articles and this page links you to all of them.

Here are a few fun facts about black holes that are contained in the articles below:

Did you know that many scientists theorize that a black hole has an opposite? Matter has anit-matter, Batman has the Joker, a black hole has a white hole. Where the event horizon of a black hole pulls in matter, a white hole shrinks from it until it collapses. They also believe that the two are connected through a Schwarzschild wormhole.

There is a single supermassive black hole at the center of every galaxy. The black holes are much more massive than known stars. The one at the center of the Milky Way(named Sagittarius A*) is 40,000 times more massive than our Sun and the accretion disk(accumulated matter in the event horizon) has 4 billion solar masses.

All black holes will eventually collapse. Steven Hawking demonstrated that all black holes should emit black body radiation. This radiation is actually a loss of mass. As a black hole losses mass it begins to lose mass at a higher rate, so the smaller the black hole the faster it loses mass until POP, no more black hole. These facts, along with several images, can be found in the links below. Happy hunting.
