Mechanism for black-hole singularity avoidance via fluctuation dominance

Conjecture that the weakening or avoidance of black-hole singularities in asymptotically safe gravity arises from the dominance of stochastic spacetime fluctuations over deterministic general-relativistic solutions at short distances within the classical–quantum gravity framework.

Background

The theory studied suggests diffusion coefficients that may grow toward the ultraviolet, implying increasingly strong stochastic fluctuations of the metric at short distances. This motivates a potential mechanism for relieving singularities.

The authors conjecture that fluctuation dominance near the would-be singularity underlies singularity avoidance/weakening observed in asymptotically safe gravity studies.
