In the last 25 years, neutrinos have revolutionised particle physics. While we have understood some of this ghost particle's physics, more precise measurements have also led to new questions. Learning more about neutrinos will help us unlock unsolved mysteries of the universe: are there additional symmetries we did not know about? What happens during a supernova? Could dark matter be made out of neutrinos? Our new experiments such as DUNE and HyperK will be multi-messenger observatories able to see neutrinos from many sources and make the next groundbreaking measurements, leading us on a path to new discoveries.
