Masters of the Universe
One of the few remaining mysteries of science is the black hole. When a star runs out of fuel to keep it burning, it explodes into a supernova(Intro. to Black Holes 1) After a supernova, some of the matter that was blown off leaves in pockets to different places in space. These pockets contract to from a pulsar, or new born star. The rest of the matter left from the massive explosion of the supernova comes back together forming a neutron star. If the dead star was too massive, the neutron star will be so large that its own gravity will crush it(Intro. To Black Holes 1). This is called its maximum density(Filkin 202). After all of the matter has collapsed in on itself, it becomes a black hole(Filkin 202). After being compressed infinitely, almost to nothing, the point in space that it makes is called a singularity(Filkin 216). The singularity is the bottom of the black hole. Every stellar body has an escape velocity(Intro. to Black Holes 1). The escape velocity is the speed at which one must be going to escape the gravity of the
Filkin, David. "Stephen Hawking's Universe." New York: Harper Collins "Introduction to Black Holes" n. pag. Online. America Online. 18 April 1999. It is possible that our galaxy is powered by a black hole(Freedman 69). Astronomers Linda Dressel, Tim Heckman, Roeland Van Der Marel and Meg Urry are looking into this(Olson 48). Because you cannot see a black hole, you can use one of two other ways to find it(Intro. to Black Holes 1). First, if a star is sighted that was circling something that could not be seen, that object is likely a black hole(Filkin 224). Second, view X-rays that are given off by the black hole through the use of radio telescopes(Filkin 225).
