black holes are known as Kerr black holes. Time runs slower where gravity is stronger. If we look at something next to a black hole, it appears to be in slow motion, and it is. The further into the hole you get, the slower time is running. However, if you are inside, you think that you are moving normally, and everyone outside is moving very fast. Some scientists think that if you enter a black hole the forces inside will transport you to another place in space and time. At the other end would be a white hole, which is theoretically a point in space that just expels matter and energy. Also as a result of the powerful gravitational waves, most black holes orbit around stars, partly due to the fact that they were once stars. This may cause some problems for the neighboring stars, for 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 can then grow strong enough (from the star's mass) as to possibly absorb another star. 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 its 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, and 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 Centaurus A. The existence of a star apparently absorbing nothingness led astronomers to suggest and confirm the existence of another black hole, Cygnus X1. By emitting gravitational waves, non-stationary b...
