Fate of spacetime singularities in quantum gravity

Determine the fate of spacetime singularities in quantum gravity.

Background

The paper analyzes the Schwarzschild black hole interior within a minisuperspace Wheeler–DeWitt framework using Ashtekar–Barbero variables, and examines the “annihilation-to-nothing” scenario as a proposed mechanism for singularity resolution.

By incorporating generalized uncertainty principle (GUP)–induced minimal-length effects, the study finds that such ultraviolet-motivated corrections suppress the annihilation-to-nothing behavior, reinforcing that the broader, long-standing problem of how quantum gravity treats spacetime singularities remains unresolved.
