Episode notes
Neutrino Detection
- Neutrinos rarely interact with matter, requiring massive detectors to spot them.
- KM3NeT detects faint light flashes from new particles created upon neutrino collisions with water molecules.
Record-Breaking Neutrino
- KM3NeT detected the highest-energy neutrino ever recorded, exceeding prior observations by 30-40 times.
- The previous record was a 6 PeV neutrino detected by IceCube.
Neutrino Origins
- The neutrino's origin remains uncertain, potentially from active galactic nuclei or cosmogenic sources.
- Current directional accuracy is insufficient to pinpoint the exact source object.
