Free Essays on Black Holes

Black Holes Everyday we look out upon the night sky, wondering and dreaming of what lies beyond our planet. The universe that we live in is so diverse and unique, and it interests us to learn about all the variance that lies beyond our grasp. Within this marvel of wonders our universe holds a mystery that is very difficult to understand because of the complications that arise when trying to examine and explore the principles of space. That mystery happens to be that of the ever clandestine, black hole. This essay will hopefully give you the knowledge and understanding of the concepts, properties, and processes involved with the space phenomenon of the black hole. It will describe how a black hole is generally formed, how it functions, and the effects it has on the universe. In order to understand what exactly a black hole is, we must first take a look at the basis for the cause of a black hole. All black holes are formed from the gravitational collapse of a star, usually having a gre at, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. The star manages to avoid collapsing at this point because of the equilibrium achieved by itself. The gravitational pull from the core of the star is equal to the gravitational pull of the gases forming a type of orbit, however when this equality is broken the star can go into several different stages. Usually if the star is small in mass, most of the gases will be consumed while s...

There is observational evidence from X-rays and the Hubble telescope that black holes do exist and might be in the center of some galaxies. The properties of a black hole are defined by its mass, charge, and spin. A black hole is a part of space that has so much mass concentrated in it that nothing could escape its gravitational pull. Black holes have so much concentration of mass that their escape velocity id so high that even light can not escape. Since nothing is faster than light, that means that nothing can escape from a black hole. Scientists in the 1930’s showed that when a massive star runs out of its hydrogen fuel, it could not support itself against its gravitational pull and collapses into a black hole. Massive objects can distort space and time, making the usual rules of geometry not applicable. Near a black hole space is extremely distorted and causes black holes to have strange properties. Black hole will have an â€Å"event horizon†. This is the boundary of the black hole. Once you pass the horizon you can not get back. Once you cross it you will keep moving to the center until you are ripped apart from the extreme gravity. There is no limit to how big a black hole can be. Technically any amount of mass can be made into a black hole if it has enough density. Since most black holes are believed to be made from dead stars, it is believed that black holes will weigh as much as massive stars. Astronomers also think that many galaxies might have very big black holes at their centers. These are thought to weigh about a million times bigger than the sun. If you were to travel to a black hole you would not feel anything at first. You would feel like you are in free fall and weightless. As you get closer and closer to the center you would start to feel the gravitational pull. The gravitational pull gets stronger the cl... Free Essays on 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 a s 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...
