What is Black Hole? A mysterious giant planets resemble a black holes, and this holes can suck all the celestial bodies arround it in any form. The mistery of black holes is similiar in concept
bermuda triangle incident.
However, the black holes is like singularity hole, size large than the sun and the sky, suck anything. In fact, the strength of the pull is causing the light does not have the power and unable to escape. The mystery that surrounds the black holes incident was only able to be studied from afar. because the ability of human science and technology still not be able to bring them up to the hole.
Black holes are formed when a massive star starts to run out of energy and he was due to run out of fuel. Although not visible, the black hole has magnetic high level. The theory of black holes actually raised over 200 years ago. in 1783, scientist, John Michell theorize about the possibility of its form a black holes after he examines Isaac Newton's Theory of gravity. He believes if the object is thrown straight up, will be separated from the influence of Earth's gravity after reaching a distance over 11 kiomoters per second.
Black Holes was first used by American theoretical physicist, John Archibald Wheeler in 1968.
Wheeler gave the name because black hole cannot be seen, the light also drawn into it so that the surrounding area becomes dark.
According to the theory of stellar evolution, the origin of the black hole is a kind of blue stars that have surface temperatures exceed 25,000 Celsius degrees. When the combustion of hydrogen in the blue star which takes approximately 10 million years completed, it became a giant blue star. Then, the star becomes cold and swapping to a giant red star. In that phase, due to its own gravitational pull, giant red star experienced a tremendous explosion called Supernova and produces two types namely star Neutron stars and black holes.
