What Is The Role Of The Central Black Hole?
At the center of galaxies there appears to be something known as a Super Massive Black Hole, which is a black hole with a mass millions to billions of times that of our sun. Studies show that orbital speeds of stars as well as gas clouds in the center of galaxies show that the masses of super massive black holes is around 1/500 of the mass of a galaxy’s bulge. It is believed although not proven that all galaxies contain super massive black holes. It is believed that super massive black holes may have played a role in galaxy formation. For a long time astronomers have suspected that galaxy evolution goes along with the formation of super massive black holes. The reason being because matter falling into a super massive black hole causes quasars. Quasars exist early in the life of galaxies, and were very common early in time when galaxies were growing swiftly. Although we do not understand this process, we have some theories as how super massive black holes formed. Some astronomers believ
