The naive calculation of black hole evaporation makes the thermal emission depend on the arbitrary high frequency behaviour of the theory where the theory is certainly wrong. Using the sonic analog to black holes-- dumb holes-- I show numerically that a change in the dispersion relation at high frequencies does not seem to alter the evaporation process, lending weight to the reality of the black hole evaporation process. I also suggest a reason for the insensitivity of the process to high frequency regime.

  1. Scattered wave functions and worldline instantons for particle production in curved spacetime

    gr-qc 2026-06 unverdicted novelty 6.0 of 10

    Extends scattered-wave-function and open-worldline-instanton methods to multidimensional curved spacetimes and demonstrates agreement on 2D metric examples.

  2. Laboratory rivers extremize friction and are cosmological analogues

    physics.geo-ph 2026-05 unverdicted novelty 6.0 of 10

    River cross-sectional profiles satisfy the Friedmann equation for an Anti-de Sitter universe; the associated action extremizes friction and dissipation, and the extremum is a maximum by second variation analysis.

  3. Simulating Hawking radiation in quantum many-body systems: deviations from the thermal spectrum

    gr-qc 2025-02 conditional novelty 5.0 of 10

    A bosonic hopping model that emulates quantum fields in curved spacetime is shown to reproduce the non-thermal E^2 corrections to Hawking radiation predicted by the tunneling method.

  4. UV Effects and Short-Lived Hawking Radiation: Alternative Resolution of Information Paradox

    hep-th 2024-11 unverdicted novelty 5.0 of 10

    Hawking radiation terminates around the scrambling time due to trans-Planckian stringy effects in GUP and string-field-theory-inspired toy models, yielding negligible evaporation and a mostly classical black hole.
