## Resource

In February 2023, the deep-sea observatory KM3NeT detected a record-breaking neutrino with an energy of 220 million billion electron volts. Known as KM3-230213A, this “ghost particle” may be a rare cosmogenic neutrino—formed when ultra-high-energy cosmic rays collide with radiation from the Big Bang. Its path points to a handful of possible cosmic origins, but its true source remains unknown. If confirmed, detections like this could open a direct window into the early universe—and potentially expose physics beyond current models.
