Description:
This paper examines the debate surrounding black holes. The paper provides theoretical speculation about the link between galaxy formation and black holes and discusses how astronomers prove the existence of black holes through the discovery of event horizons. The paper notes that while more advances are pending, proving the definitive existence of black holes, and actually identifying them, will remain a challenge for astronomers for many years to come.

From the Paper:
"In the fall of 2000 astronomer John Kormendy of the University of Texas (Austin) reported research that seemed to establish a "correlation between the size of a galaxy's bulge--the bright inner region where stars are most concentrated--and the mass of the black hole it contains." Specifically, Kormendy reported that there was a "magic fraction" and that it could be concluded that "a galaxy's central black hole carries about 15 percent of the mass of its bulge." The presence and size of the galactic bulge and a corresponding black hole are linked in other words."Kormendy also proposed an explanation for this phenomenon or a theoretical process that would justify this correlation: "The galaxy bulge and the black hole inside it form together.... Bulge formation is a process of bringing gas into the center.... Somehow the same process feeds material into the central black hole at a rate that keeps pace with the growth of the bulge."
"Thus, Kormendy is linking black holes to the formation of galaxies a connection that has become common, if not yet fully explained, amongst astronomers. That said, debate continues to rage concerning some of the most fundamental facts about black holes, even as to their existence, and their characteristics."
