Unusual neutrino signals caught in the Antarctic, explained

ANITA, a scientific instrument, detected unusual signals from high-energy neutrinos, as reported in the Astrophysical Journal. Suspended by a helium balloon over Antarctica, ANITA is designed to detect neutrinos that hit the Antarctic floor. The detected signals suggest neutrinos behaving abnormally, possibly traveling through Earth, which could indicate new physics beyond the standard model or a systematic error.

What is the primary purpose of the ANITA experiment?

How do the detected neutrinos differ from typical high energy neutrinos?

What implications could the abnormal behavior of neutrinos have on physics?

What are the potential explanations for the detections made by ANITA?
