neutrinos

Describes the work of physicists John Bahcall and Ray Davis to find and discover the nature of neutrinos, ghostly particles with no electric charge that are essential to life on Earth.

Tells how the neutrino, an almost massless subatomic particle without a charge, was discovered and helped to explain the process of radioactive decay.

Explores the development of theories regarding the existence of the neutrino and discusses how this particle was finally detected and proven to exist. Reveals what neutrinos have told us about the universe at large.
