This is a review of some recent developments on quantum gravity aspects of black hole physics. In particular, we focus on a scenario leading to the prediction of the existence of a Planck-mass quasi-stable object, that could form a component of dark matter.

  1. Loopy Black-Hole Remnants

    gr-qc 2025-08 conditional novelty 6.0 of 10

    Within a covariant effective loop quantum gravity model, black holes evaporate asymptotically to a minimum-area remnant of mass ~20.94 μg that cannot form in finite time.

  2. Thermodynamics of black and white holes in ensemble of Planckons

    gr-qc 2025-06 conditional novelty 6.0 of 10

    A toy model counting pairs of Planckons gives integer black hole entropy, negative white hole entropy, charge-independent Reissner-Nordstrom entropy, and a quantized cosmological constant.

  3. Love Numbers of Covariant Loop Quantum Black Holes

    gr-qc 2025-05 conditional novelty 6.0 of 10

    Tidal Love numbers of three covariant loop quantum black holes are shown to be generically nonzero, Planck-scale suppressed, and model-dependent in sign and logarithmic running.

  4. Singularity Avoidance in Gravitational Collapse of an Inhomogeneous Fluid in Rastall Gravity

    gr-qc 2025-07 reject novelty 5.0 of 10

    An inhomogeneous collapsing cloud in Rastall gravity can be made to bounce at a finite minimum radius, while satisfying the weak energy condition, by tuning the Rastall parameter and free functions.

  5. Echoes of Love Beyond the Horizon: A Bridge to Recovering Information from Black Holes

    gr-qc 2025-05 conditional novelty 5.0 of 10

    Black holes may acquire Planck-suppressed tidal Love numbers from quantum gravity, which the authors argue could carry information about the initial collapse and help resolve the information loss paradox.

  6. De Sitter Cores from Nonlocal Quantum Field Theories

    physics.gen-ph 2026-07 conditional novelty 2.0 of 10

    An exponential nonlocal regulator maps a point mass to a Gaussian density whose Einstein solution has a de Sitter core, reproducing (with new labeling) the known Gaussian-sourced regular black hole.
