Recently, it was shown in [1] that black holes are the source of dark energy. In [2-5], the truth or falsity of this concept has been discussed. We briefly state the arguments raised in each of these papers, but our main goal is not to accept or reject these debates. Rather, in this note, we show that black holes in specific structures, such as the Reissner-Nordstrom (R-N) black hole in the presence of quintessence, string cloud, and perfect fluid, can produce a repulsive force with respect to the weak gravity conjecture mechanism that overcomes the gravitational force.\textit{ We discuss these repulsions forces in a population of black holes of the same family can be considered as an auxiliary factor (albeit a weak factor) for the expansion of the universe}.

  1. Evaporating cosmologically coupled black holes

    astro-ph.CO 2026-07 conditional novelty 6.0 of 10

    If a black hole's mass grows with cosmic expansion, Hawking evaporation is slowed or reversed, weakening gamma-ray bounds on primordial black holes.

  2. The Influence of Stable Photon Sphere Advent on Orbital Precession in moving towards the Extremality

    gr-qc 2025-11 conditional novelty 5.0 of 10

    The periapsis shift near extremal charged black holes stays prograde in ModMax models but develops a three-region prograde-retrograde-prograde structure when a stable photon sphere coexists with extremality, which the...

  3. Holographic CFT Thermodynamics as a Bridge Between the Weak Gravity and Weak Cosmic Censorship Conjectures for EMPYM--AdS Black Holes

    hep-th 2026-06 conditional novelty 4.0 of 10

    For EMPYM–AdS black holes, the paper derives a holographic first law, a charge-to-mass bound r_min/Q̃ < 1 from the superradiance condition, first-order horizon survival under scalar absorption, and an island Page time.

  4. Probing the Weak Gravity Conjecture: Novel Aschenbach Signatures in Superextremal Non-Linear Charged AdS Black Holes

    gr-qc 2025-08 conditional novelty 4.0 of 10

    The Aschenbach angular-velocity reversal appears for an extremal, supercritically charged AdS black hole in massive gravity, supporting the claim that the effect survives beyond ordinary extremality.
