One of Stephen Hawking’s most famous theorems has been proven to be correct. The use of space-time waves is caused by the merger of two distant black holes. Hawking’s 1971 black hole area theorem from Einstein’s general theory of relativity states that the surface of a black hole will not decrease over time.
Physicists are interested in this rule because it is closely related to another rule that says that time flows in a certain direction: the second law of thermodynamics, which states that the entropy or disorder of a closed system should always increase. Since the entropy of a black hole is proportional to its surface area, both must always increase.
According to a new study, the researchers’ confirmation of the law of area seems to mean that the properties of black holes are important clues to the hidden laws that govern the universe. Interestingly, the law of area seems to contradict another accepted theorem of famous physicists: black holes must evaporate in an extremely long time, so finding the source of the conflict between the two theories can open up new physics. Surrounded by the spherical boundary of the event horizon; after that there is nothing, not even light can avoid its strong attraction.
Because, according to Hawking’s explanation of general relativity, the surface of a black hole increases as its mass increases, and because objects thrown inward cannot come out, its surface will not decrease. Researchers want to know whether it is possible to launch an object with enough force to rotate the black hole to reduce its area. The famous British physicist behind the law of area also proposed a concept called Hawking radiation, which uses a strange quantum effect to emit a cloud of particles at the edge of a black hole.
This phenomenon leads to the reduction of black holes and eventually evaporates within a period of time several times the age of the universe. This evaporation can occur long enough to not violate the law of area in the short term, but this is not comforting to physicists.
