The area theorem is probably one of the most important results in classical black hole physics. It asserts that (under certain conditions which we specify below) the area of the event horizon of a predictable black hole spacetime cannot decrease. This result bears a resemblance to the second law of thermodynamics.

The classical four laws of black hole mechanics [1] are derived from the classical geometries of the event horizons, and are just similar to the four laws of thermodynamics. It is the discovery of Hawking radiation [2] that turns the black hole mechanics into black hole thermodynamics and ... Webled in Section 4 to formulate four laws of black hole mechanics which are similar to, but distinct from, the four laws of thermodynamics. 2.
