Antarctic detector picks up signals that defy all known laws of particle physics

SMRTR summary

Scientists detected unexplained radio pulses from beneath Antarctica using the ANITA experiment. The signals suggest particles traveled through Earth, defying known physics. Researchers ruled out known sources and noise, deeming the signals "anomalous." This discovery hints at unknown particles or new particle interactions. A new detector, PUEO, is being developed to further investigate this cosmic mystery.
