Evidence the Milky Way’s Central Black Hole Exists December 9, 2009

Posted by webs21 in Uncategorized.

Recent astronomical observations have sighted a star swiftly orbiting the center of the Milky Way Galaxy. Through this observation and other X-ray binary observations, there is almost certainty that a black hole exists at the Center of our galaxy. Perhaps the most prominent evidence supporting the argument for a black hole is the X-ray binary called Cygnus X-1. This system has a very bright star with an estimated mass of 18 solar masses. Over the past several years, astronomers have been tracking the path of this star and it has been concluded that no other astronomical object has reached this close to the center of our galaxy. It is believed that this star orbiting the center of the galaxy is moving at speeds close to 11 million miles per hour and at one point in its orbit, it came within 17 light hours of the conceived black hole.

There have been other theories as to what’s at the center of our galaxy, but the fact that a seemingly invisible object with a matter equal to 2.6 million suns is enough for most to assume that a black hole is indeed at the center of the Milky Way. According to Rainer Schoedel, a German physicist, “If one accepts the universal validity of the laws of physics, it is extremely hard to avoid the conclusion that the supermassive black hole in the Milky Way does indeed exist.” What he’s referring to is that a White Dwarf star cannot exceed 1.4 solar masses. And a neutron star cannot exceed 3 solar masses. Anything above this mass will prohibit neutron degeneracy from holding off the crush of gravity in a stellar core. Since the dark object in the center of our galaxy greatly exceeds this number, the most and perhaps only logical solution is a supermassive black hole.

With compelling X-ray binary and other objective observation, there is strong evidence that a supermassive black hole does exist at the center of the Milky Way Galaxy. And since this mysterious object incapable of emitting light cannot be a White Dwarf or a neutron star, evidence shows that only a black hole can exist.
