We point out that spacetime singularities play a useful role in gravitational theories by eliminating unphysical solutions. In particular, we argue that any modification of general relativity which is completely nonsingular cannot have a stable ground state. This argument applies both to classical extensions of general relativity, and to candidate quantum theories of gravity.

  1. Regular black holes from thin-shell collapse

    gr-qc 2024-12 conditional novelty 7.0 of 10

    In D≥5 pure gravity with an infinite tower of higher-curvature terms, spherical thin-shell collapse generically produces regular black holes that bounce into new universes.

  2. The free boundary problem in general relativity

    gr-qc 2026-06 unverdicted novelty 6.0 of 10

    Treating singularities as free boundaries in the Einstein-Hilbert action yields boundary conditions excluding Kasner/BKL spacetimes while admitting conformally regular FLRW cosmologies sourced by 0 ≤ P < ρ fluids with...

  3. Quantum Schwarzschild-(A)dS Black Holes: Unitarity and Singularity Resolution

    hep-th 2025-02 conditional novelty 6.0 of 10

    Unitarity in unimodular time self-adjointness resolves the Schwarzschild-(A)dS singularity and yields a quantum-corrected metric interpolating between black and white hole states.

  4. Singularity Resolution of Quantum Black Holes in (A)dS

    gr-qc 2025-08 conditional novelty 2.0 of 10

    Requiring unitary evolution in unimodular time resolves the Schwarzschild-(A)dS singularity and yields a quantum-corrected metric with a minimum radius r_min marking a black hole to white hole transition.

  5. Towards a Non-singular Paradigm of Black Hole Physics

    gr-qc 2025-01 unverdicted novelty 1.0 of 10

    This is a review built around a week-long workshop, synthesizing the state and open problems of regular black holes and black hole mimickers as alternatives to singular black holes.
