## Black Hole Facts

Although common relativity can be utilized to carry out a semi-classical calculation of black hole entropy, this example is theoretically unsatisfying. In statistical mechanics, entropy is known as counting the number of microscopic configurations of a system that have the identical macroscopic qualities (similar to mass, cost, strain, and so on.). Without a passable principle of quantum gravity, one can’t carry out such a computation for black holes. Some progress has been made in varied approaches to quantum gravity.

In 1995, Andrew Strominger and Cumrun Vafa confirmed that counting the microstates of a selected supersymmetric black hole in string theory reproduced the Bekenstein–Hawking entropy. Since then, related results have been reported for various black holes both in string principle and in different approaches to quantum gravity like loop quantum gravity.

LIGO’s observations additionally present insights in regards to the direction a black hole spins. As two black … Read More
