Ghost-state neutrino from a black hole explosion could rewrite physics and dark matter

A 2023 ultra-energetic neutrino detected by KM3NeT may have originated from an exploding primordial black hole with a dark charge (a quasi-extremal PBH). If confirmed, such events could provide a complete catalog of subatomic particles and illuminate dark matter, but the idea is unproven and lacks corroborating detections. Researchers predict a first quasi-extremal PBH explosion could occur by 2035, highlighting a potential new window into particle physics and cosmology.

Dark-Charge Black Holes May Explain Ultra-High-Energy Neutrino Burst

KM3NeT detected a 100 PeV neutrino (KM3-230213A) with no known source. A Physical Review Letters study proposes exploding quasi-extremal primordial black holes with a dark charge as a possible origin, invoking Hawking radiation that heavier, lighter PBHs would emit high-energy particles in a final burst. IceCube has not observed a comparable event, possibly due to its different energy window. If correct, such PBH evaporations could occur roughly every decade, linking ultra-high-energy neutrinos to PBH physics.

Primordial Black Hole Bursts May Explain Ultra-Energetic Neutrinos

After a 2023 ultra-high-energy neutrino puzzled scientists, a UMass Amherst team proposes it originated from a primordial black hole explosion driven by Hawking radiation; their 'dark-charge' (quasi-extremal PBH) model could connect PBHs to dark matter and suggest these explosions may occur more often than thought, guiding future astrophysical searches.

Dark-Charge Black Holes Could Rewrite Our View of Neutrinos and Dark Matter

UMass Amherst theorists propose that explosions of quasi-extremal primordial black holes with a dark charge could produce the 2023 ultra-high-energy neutrino and, if true, link Hawking radiation to primordial black holes and dark matter, offering a new path to understand fundamental physics.
