Antarctic Detector Picks Up Bizarre Radio Pulses Defying Physics

The Antarctic Impulsive Transient Antenna (ANITA) experiment has detected unusual radio pulses seemingly originating from below the ice, contradicting current particle physics understanding. These signals, unlike expected cosmic ray reflections, appear to come from beneath the horizon. Researchers have ruled out known particles like neutrinos, suggesting the possibility of new particles or interactions, potentially even hinting at dark matter. A larger detector, PUEO, is being developed to investigate further.
