WebJun 18, 2024 · 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. WebFig. 1 is called a black hole1. The “interior” of H is the interior of the black hole (spacetime region where light is “trapped”, i.e. cannot escape to infinity), while H (which marks the great “divide” between trapped light, and light escaping at infinity) is the horizon, or the surface of the black hole. Note the presence ...
