The firewall transformation for black holes and some of its implications

TL;DR

This paper proposes a new approach to understanding black hole physics by introducing transformations that remove firewalls, incorporating antipodal identification and CPT symmetry, leading to novel constraints on spacetime topology and boundary conditions.

Contribution

It introduces a transformation-based framework that addresses black hole unitarity and firewall issues, suggesting new constraints on topology and boundary conditions in quantum gravity.

Findings

Antipodal identification implies CPT symmetry at the horizon.

Transformations can potentially remove black hole firewalls.

New constraints on spacetime topology are proposed.

Abstract

A promising strategy for better understanding space and time at the Planck scale, is outlined and further pursued. It is explained in detail, how black hole unitarity demands the existence of transformations that can remove firewalls. This must then be combined with a continuity condition on the horizon, with antipodal identification as an inevitable consequence. The antipodal identification comes with a CPT inversion. We claim to have arrived at 'new physics', but rather than string theory, our 'new physics' concerns new constraints on the topology and the boundary conditions of general coordinate transformations. The resulting theory is conceptually quite non trivial, and more analysis is needed. A strong entanglement between Hawking particles at opposite sides of the black hole is suspected, but questions remain. A few misconceptions concerning black holes, originating from older investigations, are discussed.
