They're everywhere, but you will never see one. Trillions of them are flying through you right this second, but you can't feel them. These ghost particles are called neutrinos and if we can catch them, they can tell us about the furthest reaches and most extreme environments of the universe. Neutrinos are elementary particles, meaning that they can't be subdivided into other particles the way atoms can. Elementary particles are the smallest known building blocks of everything in the universe, and the neutrino is one of the smallest of the small. A million times less massive than an electron, neutrinos fly easily through matter, unaffected by magnetic fields. In fact, they hardly ever interact with anything. That means that they can trav...
