Summary

Story summary

Physicists at the University of Massachusetts Amherst propose that a neutrino detected in 2023 came from a quasi-extremal primordial black hole explosion.
Quasi-extremal primordial black holes may form shortly after the Big Bang and could emit Hawking radiation.
The model suggests explosions could occur about once per decade, enabling tests of dark matter.
It introduces a 'dark charge' that alters PBH behavior and may explain discrepancies between KM3NeT and IceCube neutrino observations.
