The first official evidence of a key imbalance between neutrinos and antineutrinos provides one of the best clues for why the universe contains something rather than nothing. Physicists have detected ...

Two papers challenged the existence of theorized particles called sterile neutrinos that might account for mysteries like the cosmos’s dark matter. By Kenneth Chang Just how many types of neutrinos ...

Neutrinos are fundamental particles that interact rarely with matter and are therefore notoriously difficult to detect. There are three known types of neutrino, but anomalous experimental results have ...

The highest energy neutrino ever detected from space may finally have an origin story. Mathematical analyses suggest that the ghost particle could’ve come from a theoretical object known as a ...
