Understanding Black Holes Essay -- Astronomy, research papers
Throughout the modern era of astronomy, a single(a) type of celestial object has puzzled astronomers more than any other. portentous holes, whose existence was only verified in the early 1990s, have intrigue scientists ever since Einstein 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, hints, and even light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of billet and time however, many of these recent discoveries lead to more unanswered questions. Nevertheless, the basic life cycle of a black hole is now soundless in ways thought to be impossible only twenty years ago.In order to get down to grasp the destructive suck of a black hole, one must first understand its creation. particularly enough, a black hole underside only be create from the death of a star, but no ordinary star can create a blac k hole it has to be a super-massive star. Stars be mainly of hydrogen, and the hydrogen atoms are under such great ram that they collide and cause a fusion response, 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 balloon and engulf the inner planets (including earth) before contracting. An average sized star bid that of our sun will now become the size of the estate (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.
