Particle physicist Kirsty Duffy uncovers the mysteries of neutrinos, and the experiments searching for the answers.

Right now, around 100 billion neutrinos are passing through your thumbnail. You will not feel a single one. These ghostly subatomic particles are the most abundant matter particle in the universe, produced in the sun, in supernovae, at the heart of the Earth, and in bananas. They pass through almost everything without leaving a trace. And yet they may hold the answer to one of the most fundamental questions in all of physics: why does the universe exist?
