Famous Stephen Hawking theory about black holes confirmed

The areas of black holes are tied to the amount of disorder in the universe..

One of Stephen Hawking’s most famous theorems has been proven right, using ripples in space-time caused by the merging of two distant black holes.

The black hole area theorem, which Hawking derived in 1971 from Einstein’s theory of general relativity, states that it is impossible for the surface area of a black hole to decrease over time. This rule interests physicists because it is closely related to another rule that appears to set time to run in a particular direction: the second law of thermodynamics, which states that the entropy, or disorder, of a closed system must always increase. Because a black hole’s entropy is proportional to its surface area, both must always increase.

According to the new study, the researchers’ confirmation of the area law seems to imply that the properties of black holes are significant clues to the hidden laws that govern the universe. Oddly, the area law seems to contradict another of the famous physicist’s proven theorems: that black holes should evaporate over extremely long time scale, so figuring out the source of the contradiction between the two theories could reveal new physics.
