Black Holes

Today in astronomy, black holes are one of the most talked about subjects because astronomers still don't have all the answers to them. You may ask why it would be important to study something that has no effect on us and is astronomical distances away. One reason is to get a further understanding of the universe, its creation, and its possible future. A second reason is some scientist believe that it is possible to use black holes for incredibly fast space travel or even time travel. In this paper I will explain more about black holes and how they may be used it the future.
A black hole is a region of space whose attractive gravitational force is so intense that no matter, light, or communication of any kind can escape. There are only three parts to a black hole. The event horizon, the singularity, and the Schwarzschild radius. The event horizon is the black hole's surface. It is in the shape of a sphere and has no matter at its location accept for the instant that matter crosses it into the black hole. Once past the event horizon nothing can escape the black hole, not even light. The singularity lies in the center of the black hole and is where matter is crushed into infinite density. The Schwarzschild radius is the distance from the center of the black hole to its boundary. Since black holes take in everything that crosses its path, scientist can't get a better look at the inside of a black holes because no electro magnetic radiation can escape it. But they have discovered that a lot of the time the gas around black holes can be very bright as illustrated in the picture.
Once matter enters a black hole, it keeps only three properties that it had before entering the black hole, its mass, angular momentum, and electrical charge. All other concepts like protons, neutrons, atoms, electrons, and molecules no longer apply.
There are two types of black holes, ones that rotate and ones that don't. Schwarzschild black hol...
