Besides scaring everyone for a few months by apparently breaking the limit of the speed of light neutrinos are particles of profound importance in cosmology and particles physics. Despite its extraordinary abundance in the universe—billions pass through your body every second—this ghostly particle is notoriously difficult to trap, inspiring some of the most sophisticated detectors in science just to study it. The elusive neutrino holds clues to some of the most profound questions in particle physics: What happened in the briefest moments after the Big Bang? Why does the universe contain more matter than antimatter? This video will attempt to tackle these mysteries. For more high quality videos use the links below.
