WebJan 30, 2024 · How is there enough space on the surface (2D) to encode something which is in 3D. The planck distance is the same in the black hole as in the universe. So how can the black hole encode information about an object in 3D that is both uniformly complex and as dense as the black hole? short bebe meninoThe four laws of black hole mechanics are physical properties that black holes are believed to satisfy. The laws, analogous to the laws of thermodynamics, were discovered by Jacob Bekenstein, Brandon Carter, and James Bardeen. Further considerations were made by Stephen Hawking. The laws of black hole mechanics are expressed in geometrized units. The horizon has constant surface gravity for a stationary black hole. sandwich tescoWebJun 23, 2024 · As a black hole gobbles up more matter, its mass and surface area grow.
