What is in a black hole
Apr 9, 2019 · A black hole is a dense, compact object whose gravitational pull is so strong that nothing can escape, not even light. Black holes are thought to result from the collapse of very massive stars. The gravity is so strong because their mass has been squeezed into a tiny space. The boundary in space around a black hole is called the "event horizon."
The Bekenstein-Hawking entropy or black hole entropy is the amount of entropy that must be assigned to a black hole in order for it to comply with the laws of thermodynamics as they are interpreted by observers external to that black hole.This is particularly true for the first and second laws. Black hole entropy is a concept with …
