Understanding Black Holes Essay -- Astronomy, research papers

Through show up the modern era of astronomy, a single suit of celestial object has puzzled astronomers more than any other. Black fixings, whose existence was only verified in the early 1990s, have fascinated scientists ever since champion first proposed the theoretical concept in the 1930s. A black hole is an object so tiny, but also so dense, that it has the power to pull planets, stars, and plain light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of space and time however, many of these recent discoveries glide by to more unanswered questions. Nevertheless, the basic life cycle of a black hole is now unders aliked in ways thought to be unattainable only twenty years ago.In order to begin to grasp the destructive force of a black hole, one must first register its creation. Oddly enough, a black hole brook only be formed from the death of a star, but no ordinary star can create a black hole it has to be a super-massive star. Stars consist mainly of hydrogen, and the hydrogen atoms are under such great pressure that they bump around and cause a fusion reaction, which creates helium. This constant fusion reaction within the star is what keeps it from collapsing onto itself, thereby sustaining its massive size for billions of years. When a normal-sized star begins to run out of hydrogen, eventually the entire star will begin to run out of hydrogen and the star will actually expand and engulf the inner planets (including earth) ahead contracting. An average sized star like that of our sun will now become the size of the Earth (Ando, 2004). This is called a white dwarf, and although white dwarves are too dim to be seen from Earth with the naked eye, they doe cont... ... holes die but it takes awhile.
