Black Hole
Curiosity in the study of Black holes was from a long time. Even though the scientist didn't knew what was there in the space that had a strange behavior. They were very well on the right track in the search of that unknown object. It was first predicted in 1783 by John Mitchell and called these strange objects as dark stars. He also predicted that as far a star with a fixed mass and is within its circumference then light would not be able to escape from its surface. Further in 1796, Pierre Simon Lapace also made the same prediction as John Mitchell. The formation and the behavior of black holes are the most unique behavior that scientist had never learned and thus it further deepened their interests in black hole. The real start of modern black holes theory began in 1915, when Albert Einstein and David Hilbert formulated the Einstein field equation. This equation simply describes how mass introduces curvature to spacetime. For example: a ray of light from a distant star passing close to the surface of sun will be bent to a small but measurable amount this is called the curvature to spacetime. This equation further led to the Schwarzschild solution, discovered by Karl Schwarzchild in 1916. This predicted the properties o
f nonspinning, uncharged black holes. Also in the same year, German physicist Hans Reissner discovered a solution to the Schwarzchild equation that described a nonspinning, charged black hole. In 1918, Dutch physicist Gunnar Nordstrom came up with the same solution. All these discoveries laid the foundations for future work on black holes. The formation of black hole was concluded by the astronomers as when a star which is more massive than Sun will evolve more quickly will be more spendthrift on its energy resources. Probably is looses mass at rate of something like 80,000 million tons and thus it cant stand this depletion of resources for long time while Sun losses mass at rate of 4,000,000. So the life of heavy mass star is much less then that of Sun. When the star will collapses as its fuel runs out, the reactions will be become completely out of control. Thus there will be catastrophic explosion which is called as supernova. Much of the star's material away is blown in the space and its residue shrinks down into a very small dense body. During this the protons and electrons inside an atom runs together, making up neutrons, and thus in the end we are left with neutron star. Supernovas are not common at all. In the past thousand years or so there have been four in our galaxy during 1006, 1054, 157, and 1604. But these supernova outbursts were not as violent as scientist has seen and study supernova outburst in different galaxies. In a massive star that is ten ti
