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

2021103 points34 comments Science & Space details

On December 8, 2016,* a high-energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts (PeV) of energy.
