The process obeys the laws of black hole mechanics.
2.
The laws of black hole mechanics, initially proved for event horizons, are generalized to isolated horizons.
3.
The four "'laws of black hole mechanics "'are physical properties that black holes are believed to satisfy.
4.
Even more remarkably, there is a general set of laws known as black hole mechanics, which is analogous to the laws of thermodynamics.
5.
This seemingly causes a violation of the second law of black hole mechanics, since the radiation will carry away energy from the black hole causing it to shrink.
6.
There is strong evidence that the laws of black hole mechanics are, in fact, a subset of the laws of thermodynamics, and that the black hole area is proportional to its entropy.
7.
For instance, by the second law of black hole mechanics, the area of the event horizon of a general black hole will never decrease with time, analogous to the entropy of a thermodynamic system.
8.
This allows the formulation of the first law of black hole mechanics as an analogue of the first law of thermodynamics, with the mass acting as energy, the surface gravity as temperature and the area as entropy.
9.
"' James Maxwell Bardeen "'( born May 9, 1939 ) is an American physicist, well known for his work in general relativity, particularly his role in formulating the " laws of black hole mechanics ."
10.
This leads to a modification of the original laws of black hole mechanics : for instance, as the second law of black hole mechanics becomes part of the second law of thermodynamics, it is possible for black hole area to decrease as long as other processes ensure that, overall, entropy increases.
