Natural Phenomena (BLACK HOLE)

Black Hole
Black holes are part of the time space which is the strongest gravity, even the light cannot escape. General Theory of Relativity predicts that it takes mass to create a Black Hole in the Time Space. Around the Black Hole there is a surface that is called Event Horizon. This hole is called "black" because it absorbs whatever is around and can not come back, not even light. Theoretically, black holes can possess any size, from microscopic to the observable size of the universe. The Quantum Field Theory in Curved Space-time predicts that Event Horizon emits nearby radiation with limited temperatures. This temperature is inversely proportional to black hole mass, making it difficult to observe black holes with mass of stars or more.

The theory of black holes was first proposed in the 18th century by John Michell and Pierre-Simon Laplace, developed by German astronomer Karl Schwarzschild, in 1916, based on Albert Einstein's general theory of relativity, and increasingly popularized by Stephen William Hawking. The term black hole became popular when John Archibald Wheeler used it in his lectures in 1967. Although he was widely regarded as the first originator of this term, he always dismisses the claim that he was not the inventor of this term.

The Origin of The Black Hole
At first, the star is formed with conditions where the level of radiation and gravity are balanced. As the star ran out of fuel to do the fusion, the radiation level went out weaker than the inward gravitational force. From there, the star collapses, and then experiences a supernova explosion. In this explosion, there are two possible outcomes. One of them is a black hole.

Death Black Hole
The black hole will die through the Hawking Radiation process. This process is as simple as disassembling parts per part of a black hole. Over time, the black hole will continue to shrink and shrink, until it ends up with a massive explosion, even thousands of times larger than the Hiroshima and Nagasaki bombs. However, this process tends to take a long time.While the black hole size must be big. Then it could be that we as human beings will not witness anything from this event.
