WebIn 1971, Stephen Hawking proposed the area theorem, which set off a series of fundamental insights about black hole mechanics. The statement was a curious parallel … The second law of thermodynamics requires that black holes have entropy. If black holes carried no entropy, it would be possible to violate the second law by throwing mass into the black hole. The increase of the entropy of the black hole more than compensates for the decrease of the entropy carried by the object that was swallowed. In 1972, Jacob Bekenstein conjectured that black holes should have an entropy, where by the sa…
