大統一理論
The goals of the project were to: study the unification of all forces by observing proton decay (a very rare phenomenon expected to occur according to some Grand Unified Theory (GUT) models but never observed), study the galactic supernovae through neutrino-observations, study terrestrial and solar neutrinos (neutrinos are formed in nuclear processes), study the excess of matter over antimatter in the universe through observing neutrino oscillations in collaboration with CERN (that provides the neutrino-beams for the experiment; neutrinos are made in the CERN and the sent as underground beam for hundreds of kilometers through the Earth to the detectors).
