IceCube detection of high-energy particle proves 60-year-old physics theory

On December 6, 2016, a high-energy particle hurtled to Earth from outer space at close to the speed of light. It triggered the sensors of the IceCube Neutrino Observatory, a massive telescope buried in the Antarctic glacier. IceCube had seen a Glashow resonance event, a phenomenon predicted by Nobel laureate physicist Sheldon Glashow in 1960.
