Ghost-state neutrino from a black hole explosion could rewrite physics and dark matter
TL;DR
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.
