A mysterious neutrino detected in 2023 may be debris from an exploding primordial black hole. Scientists say the ultra-energetic particle defies known cosmic sources and could represent Hawking radiation, offering rare insight into early-universe physics and the possible nature of dark matter while challenging theories of black holes and cosmology.A mysterious neutrino detected in 2023 may be debris from an exploding primordial black hole.
