Are Neutrinos the Key to the Universe?

At a conference in 1932, the Nobel Prize-winning nuclear physicist, Enrico Fermi, became the first scientist to use the term “neutrino” publicly. Since then, scientists have experimentally confirmed Fermi's theories and directly observed neutrinos, but the subatomic particles are still not fully understood. In this episode of the Harvard Horizons podcast, PhD student Nicolò Foppiani asks whether the "sterile neutrino" exists and whether it could explain one of the greatest mysteries in astrophysics: the source of dark matter.
