An interpretation for the entropy of a black hole

TL;DR

This paper explores the meaning of black hole entropy, proposing it measures the uncertainty of initial matter configurations, and suggests Hawking radiation can carry away all information about black hole formation and collapse.

Contribution

It introduces a new interpretation of black hole entropy related to initial matter configurations and demonstrates Hawking radiation can encode all information about black hole processes.

Findings

Black hole entropy measures initial matter configuration uncertainty.

Hawking radiation can carry away all information about black hole formation.

Gravitational waves alone cannot carry all information about black hole processes.

Abstract

We investigate the meaning of the entropy carried away by Hawking radiations from a black hole. We propose that the entropy for a black hole measures the uncertainty of the information about the black hole forming matter's precollapsed configurations, self-collapsed configurations, and inter-collapsed configurations. We find that gravitational wave or gravitational radiation alone cannot carry all information about the processes of black hole coalescence and collapse, while the total information locked in the hole could be carried away completely by Hawking radiation as tunneling.
