The neutrino is among the cagiest of particles, a subatomic wisp so ephemeral it could pass through light-years of lead with more ease than a hot knife through butter. 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. A closer look could change everything. 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? Join leading researchers as they chase neutrinos and other elusive particles in search of nature’s fundamental order.
