Neutrinos are like cosmic ghosts.
Each and every second, billions of the elusive subatomic particles pass through the Earth and everything on the planet. They pass through unnoticed. Neutrinos can travel 10,000 light years without disturbing anything. A collaboration of scientists would love to detect a neutrino's passing. Researchers from Arizona State University, the California Institute of Technology, Stanford, and the University of Alabama are using a 200-ton underground facility to do just that.
