neutrinos
Chargeless subatomic travelers
Neutrinos are subatomic particles with no electric charge and nearly zero mass.
They pass through ordinary matter almost without interaction—billions stream through your body every second undetected.
Produced by nuclear reactions in the sun, reactors, and exploding stars, neutrinos are notoriously difficult to study precisely because they interact so weakly with anything else.
