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.
