Black Holes
... 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 some of it escapes. This occurs because there is not a tremendous gravitational pull upon those gases and therefore the star weakens and becomes smaller. It is then referred to as a White Dwarf. If the star was to have a larger mass however, then it may possibly Supernova, meaning that the nuclear fusion within the star simply goes out of control causing the star to explode. After exploding a fraction of the star is usually left (if it has not turned into pure gas) and that fraction of the star is known as a neutron star. A black hole is one of the last option that a star may take. If the core of the star is so massive (approximately 6-8 solar masses; one solar mass being equal to the sun's mass) then it is most likely that when the star's gases are almost consumed those gases will collapse inward, forced into the core by the gravitational force laid upon them. After a black hole is created, the gravitational force continues to pull in space debris and other type of matters to help add to the mass of the core, making the hole stronger and more powerful. Most black holes tend to be in a consistent spinning motion. This motion absorbs various matter and spins it within the ring (known as the Event Horizon) that is formed around the black hole. The matter keeps within the Event Horizon until it has spun into the centre where it is concentrated within the core adding to the mass. Such spinning black holes are known as Kerr Black Holes. Most black holes orbit around stars due to the fact that they once were a star, and this may cause some problems for the neighboring stars. If a black hole gets powerful enough it may actually pull a star into it and disrupt the orbit of many other stars. The black hole could then grow even stronger (from the star's mass) as to possibly absorb another. When a black hole absorbs a star, the star is first pulled into the Ergosphere, which sweeps all the matter into the Event Horizon, named for it's flat horizontal appearance and because this happens to be the place where mostly all the action within the black hole occurs. When the star is passed on into the Event Horizon the light that the star endures is bent within the current and therefore cannot be seen in space. At this exact point in time, high amounts of radiation are given off, that with the proper equipment can be detected and seen as an image of a black hole. Through this technique astronomers now believe that they have found a black hole known as Cygnus X1. This supposed black hole has a huge star orbiting around it, therefore we assume there must be a black hole that it is in orbit with. The name "black hole" was named such, because of the fact that light could not escape from the gravitational pull from the core, thus making the black hole impossible for humans to see without using technological advancements for measuring such things like radiation. The second part of the word was named "hole" due to the fact that the actual hole, is where everything is absorbed and where the centre core presides. This core is the main part of the black hole where the mass is concentrated and appears purely black on all readings even through ...
