The Thermodynamics of Black Holes

TL;DR

This paper reviews the current understanding of black hole thermodynamics, including classical laws, Hawking radiation, entropy bounds, and open questions in the field.

Contribution

It provides a comprehensive overview of classical and quantum aspects of black hole thermodynamics and discusses various approaches to entropy calculation.

Findings

Black holes obey thermodynamic laws.

Hawking radiation leads to black hole evaporation.

Entropy bounds are fundamental but not fully understood.

Abstract

We review the present status of black hole thermodynamics. Our review includes discussion of classical black hole thermodynamics, Hawking radiation from black holes, the generalized second law, and the issue of entropy bounds. A brief survey also is given of approaches to the calculation of black hole entropy. We conclude with a discussion of some unresolved open issues.
