Story summary

In a groundbreaking discovery, researchers at the IceCube Neutrino Observatory in Antarctica revealed that fewer than 70% of ultrahigh-energy cosmic rays are protons, upending previous beliefs. After 12.6 years of data collection without detecting high-energy neutrinos, this finding calls for a reevaluation of current theories and emphasizes the urgency for further investigation to address conflicting observations.
