Tiny black holes (NCYT) are the effect of the fall down of individual stars. But the centers of most galaxies, including our own Milky Way, are unavailable by what is popularly known as black holes "supermassive". These holes whose accumulation is usually between one million and ten billion times the mass of our Sun Astrophysicists have long debated how they could grow as supermassive black holes for 14,000 million years since it was formed the universe. Some believe that black holes grow primarily by sucking large quantities of gas; others advocate the theory that grows primarily through the capture and absorption of stars. The second source of "nutrition" seems the most likely, judging by the results of a study conducted by the team of Ben Bromley astrophysicist at the University of Utah in the United States.
