Study shows neutrinos possess m

Study shows neutrinos possess m

A team of Japanese and U.S. scientists have found evidence showing for the first time that neutrinos -- tiny, electrically neutral, subatomic particles -- possess mass, contradicting the standard theory of particle physics. The Super-Kamiokande group made the finding by using a 50,000-ton tank (in the photo) of highly purified water located about 1,000 meters underground in the Kamioka Mine in Gifu Prefecture, central Japan. ==Kyodo
