New IceCube detection proves 60-year-old theory
On December 8, 2016, a high-energy particle called an electron antineutrino was hurtling through space at nearly the speed of light. Normally, the ghostly particle would zip right through the Earth as if it weren’t even there.
 
But this particle just so happened to smash into an electron deep inside the South Pole’s glacial ice. The collision created a new particle, known as the W
– boson. That boson quickly decayed, creating a shower of secondary particles.
 
The whole thing played out in front of the watchful detectors of a massive telescope buried in the Antarctic ice, the IceCube Neutrino Observatory. This enabled IceCube to make the first ever detection of a Glashow resonance event, a phenomenon predicted 60 years ago by Nobel laureate physicist Sheldon Glashow. ....
