Laws of black hole mechanics
Web17 jun. 2024 · Black hole, as an outstanding prediction of Einstein gravity, is one of the most fascinating and mysterious compact subjects. This prediction is confirmed by observational data (1; 2). In addition, one of the remarkable achievements of theoretical physics is related to the discovery of a profound connection between the laws of black … Web8 dec. 2024 · The first law of black hole mechanics has been the main motivation for investigating thermodynamic properties of black holes. The first version of this law was proved in \cite {Bardeen:1973gs} by considering perturbations of an asymptotically flat, stationary black hole spacetime to other stationary black hole spacetimes.

But to verify the second law in the extremal and non- extremal configurations one has to be very cautious as it gets strongly affected by the choices of the values of the black hole parameters and …
