New measurements aim to change that. Neutrinos are the featherweights of the subatomic world. These extremely plentiful, rarely interacting particles are at least 500,000 times lighter than electrons. They are produced in the sun, in exploding stars, and in decay processes on Earth—even ones in your own body. But they interact so infrequently with other matter that you’d hardly know there are so ...
