Frontiers Thermodynamics of Many Black Holes

The 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. WebBlack hole temperature is inversely related to mass. All known black hole candidates are so large that their temperature is far below that of the cosmic background radiation, which means they will gain energy on net by absorbing this radiation. They cannot begin to lose energy on net until the background temperature falls below their own ... gallant property and development services https://arodeck.com
