We prove the Penrose-Wall singularity theorem in the full semiclassical gravity regime, significantly expanding its range of validity. To accomplish this, we modify the definition of quantum-trapped surfaces without affecting their genericity. Our theorem excludes controlled "bounces" in the interior of a black hole and in a large class of cosmologies.

  1. Fundamental Complement of a Gravitating Region

    hep-th 2025-05 conditional novelty 8.0 of 10

    A gravitating region's hologram is the spacelike complement of the hologram of its fundamental complement, generalizing entanglement-wedge complementarity to arbitrary spacetimes and recovering AdS/CFT.

  2. Complete Quantum Stress Tensor Inside a Four Dimensional Schwarzschild Black Hole: A Divergent Focusing Source

    gr-qc 2026-07 conditional novelty 7.5 of 10

    Complete interior RSET of a massless scalar in Unruh and Hartle–Hawking states approaches a universal conserved r^{-6} focusing tensor near the Schwarzschild singularity.

  3. Tests of restricted Quantum Focusing and a new CFT bound

    hep-th 2025-10 conditional novelty 6.0 of 10

    From rQFC, a new CFT bound follows that forbids the QNEC from saturating faster than O(Σ^{d−2}) in near-vacuum states, while rQFC is proven in JT gravity and explicit QFC counterexamples are constructed.
