The team is trying to solve the mystery of extremely energetic cosmic rays that hit our atmosphere, sparking showers of other particles. Physicists have no idea what the rays are, where they come from, or how they travel so fast. One possibility is that they are neutrinos, in which case some would make it into the ocean. If they then interact with atoms in…
