Neutrino - GRB coincidence (?)

Another intriguing multi-messenger coincidence: A (very) high-energy neutrino candidate event was detected by the IceCube neutrino telescope at 2025-03-09 07:36:04. The preliminary data reconstruction gives an enormous energy of 4132 TeV (>4 peta electronvolt = 4x10^15 eV!). It has a 50% probability of being of astrophysical origin (signalness) and instead of a noise event induced for example by cosmic rays in the Earths atmosphere. This combination (very high energy but only relatively low sig...
