Fermilab's video: Interview with Nobel laureate Carlo Rubbia about neutrino research

In this 5-minute video, Nobel laureate Carlo Rubbia explains why mysterious particles called neutrinos could be the key to understanding the nature of the universe. He talks about the search for a fourth type of neutrino and why the universe would not exist without neutrinos. He describes how scientists aim to unveil the secrets of the neutrino with the ICARUS (https://icarus.fnal.gov) and DUNE (https://fnal.gov/dune) neutrino experiments, hosted by Fermilab (https://fnal.gov). He recalls why early in his career he chose liquid argon as his material of choice to collect information about neutrino interactions with matter.
