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. 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...

  2. 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.

  3. 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.
