Resolution of black hole singularities

Determine a specific, consistent mechanism that resolves the curvature singularities inside black holes predicted by general relativity, and characterize how the singular region is avoided or replaced by a regular spacetime within a quantum gravitational description.

Background

General relativity predicts the formation of curvature singularities inside black holes, signaling a breakdown of classical physics. A widely held view is that a quantum theory of gravity is required to address and potentially resolve these singularities.

The paper revisits Wheeler–DeWitt (WDW) quantization for black hole interiors and examines higher-curvature corrections within an effective field theory framework, arguing that true resolution necessitates ultraviolet (UV) physics beyond low-energy GR. The broader, foundational problem of singularity resolution remains explicitly acknowledged as open.
