In February 2023, a detector 3.5 kilometres beneath the Mediterranean caught the aftermath of the most energetic neutrino ever seen — a 220-petaelectronvolt ghost particle, roughly 16,000 times beyond CERN’s strongest collisions, with no confirmed source anywhere in the sky.

In February 2023, a single particle crossed a detector resting on the floor of the Mediterranean, and it carried more energy than any neutrino ever recorded. Two years of careful analysis later, the team behind the detector put a number on it: around 220 petaelectronvolts, roughly 16,000 times the energy of the most violent collisions [...] The post In February 2023, a detector 3.5 kilometres beneath the Mediterranean caught the aftermath of the most energetic neutrino ever seen — a 220-petaelectronvolt ghost particle, roughly 16,000 times beyond CERN’s strongest collisions, with no confirmed source anywhere in the sky. appeared first on Space Daily .
