Ghost-induced phase transition in the final stages of black hole evaporation

TL;DR

This paper proposes that quantum-induced ghost instabilities can cause an evaporating black hole to transition into a stable naked singularity, potentially resolving the information paradox.

Contribution

It introduces a novel high-energy phase transition driven by ghost instabilities in black hole evaporation, linking quantum corrections to classical singularity issues.

Findings

Ghost instability triggers a phase transition in black hole evolution.

Black holes may evolve into stable naked singularities at high energies.

This process could resolve the black hole information paradox.

Abstract

We explore a novel scenario in which a quantum-induced ghost instability drives the natural evolution of an evaporating Schwarzschild black hole toward a stable naked singularity. This process, arising from quadratic curvature corrections to the Einstein-Hilbert action at high energies, circumvents the inconsistencies associated with classical naked singularities. The onset of ghost-driven instability signals a phase transition that fundamentally alters black hole evaporation, rendering the information paradox moot as it merges with the singularity issue. Our findings suggest a new pathway for black hole evolution at high-energy scales, offering insights that may bridge key gaps until a full theory of quantum gravity is realized.
