Black holes: Their large interiors

TL;DR

This paper discusses the large interior volumes of static and spinning black holes, expanding on previous remarks and providing insights into their internal structure.

Contribution

It extends prior work on black hole interiors to include spinning black holes, highlighting their large internal volumes.

Findings

Static black holes have large interior volumes.

Spinning black holes also possess large interiors.

The work generalizes previous observations to rotating cases.

Abstract

Christodoulou and Rovelli have remarked on the large interiors possessed by static black holes. We amplify their remarks, and extend them to the spinning case.
