The T-domain and extreme matter phases inside spherically symmetric black holes

TL;DR

This paper explores the interior structure of black holes, focusing on the T-domain, presenting solutions including non-singular ones, and revealing how exotic matter phases can form inside the horizon without external detection.

Contribution

It introduces a detailed analysis of the T-domain inside black holes, including duality with R-domains and a singularity theorem independent of energy conditions.

Findings

Multiple local T-domain solutions, including non-singular ones.

Exotic matter phases can form inside the horizon without external evidence.

A new singularity theorem independent of energy conditions.

Abstract

Black hole interiors (the $T$-domain) are studied here in great detail. Both the {\em general} and particular $T$-domain solutions are presented including non-singular ones. Infinitely many local $T$-domain solutions may be modeled with this scheme. The duality between the $T$ and $R$ domains is presented. It is demonstrated how generally well behaved $R$-domain solutions will give rise to exotic phases of matter when collapsed inside the event horizon. However, as seen by an external observer, the field is simply that of the Schwarzschild vacuum with well behaved mass term and no evidence of this behaviour may be observed. A singularity theorem is also presented which is independent of energy conditions.
