Cosmic Quicksand
A voracious swirling orifice lies in the center of every galaxy, even our own Milky Way. Anything that crosses over into its event horizon will be ripped to pieces. Some of these pieces are swallowed up, while others are propelled into the universe at one half the speed of light. Despite these grim facts, Black Holes are much less menacing than they seem. Although objects that cross over into the event horizon (the "mouth" of the Black Hole) are lost forever, Black holes also contribute energy and star-making gas and dust to the galaxy that surrounds it. Everything emitted from a Black Hole provides valuable information about how our universe functions.Everything in the universe has a birth, a life, and a death. Just as people are said to live on through their children, a star also lives on in the form of a Black Hole. A Black Hole is created when a star dies. Te inward gravitational pull of the star becomes so great that it collapses into itself and turns into a void with zero mass. This void is called a Black Hole. A Black Hole is not a giant vacuum. Rather, it is an object of infinite density and gravity that bends the space and time around it. Time moves more slowly the closer it gets to the center. On the very
edge of the event horizon, time actually stops! Black holes are not all alike. Stellar Black Holes are not found in the center of galaxies. In fact, we now know of three distinct kinds of black holes; Supermassive, Mid-mass, and Stellar. These black holes are remnants of deceased stars that once formed binary star systems. Most of the detectable rays emitted from Black Holes are X-Rays . " The Chandra X-Ray Observatory has discovered X-Rays that are believed to be coming from the Supermassive Black Hole in the center of our own Milky Way. These Black Holes have masses of millions of suns and produce huge amounts of energy. What we have found in the VLA data is the first direct evidence that the black holes actually do coalesce. Andrew Fabian presented the now-accepted argument that Black Holes produce anywhere from ten to fifty per-cent of all energy produced by stars in the universe . In August of 2002, scientists in New Mexico analyzed a pair of galaxies that had merged. Scientists are not sure how these Supermassive Black Holes form, but they have come up with two possible theories. Although nothing can escape the event horizon, the area surrounding a Black Hole is extremely turbulent and produces copious amounts of energy. This Black Hole is thought to have 2. Any star in the universe with a core more massive than three solar masses is destined to become a Black Hole at the end of its life.
