ANITA Detects UHE Radio Signals Defying Standard Model Predictions
ANITA Detects UHE Radio Signals Defying Standard Model Predictions The Antarctic Impulsive Transient Antenna (ANITA) experiment, designed to detect high-energy cosmic neutrinos, has registered anomalous upward-traveling radio pulses originating from deep within the Earth. These signals, detailed in Physical Review Letters, violate established particle physics models, as such pulses should be absorbed by the Earth’s crust before detection. ANITA’s balloon-borne detectors, positioned 30-39 km above Antarctica, observed pulses at steep angles (≈30° below the ice surface), implying a trajectory through…
