The Penrose Conjecture

The Penrose Conjecture is a mathematical idea suggesting that in a universe governed by Einstein's theory of general relativity, the total mass of a black hole system can be predicted based on the size of its surrounding boundary, specifically the outermost surface called the apparent horizon. It proposes a precise relationship between mass and surface area, implying that the larger the black hole's boundary, the more mass it contains. This relationship helps physicists understand black hole formation and stability, tying the geometry of spacetime to the physical properties of these extreme objects.
