The project aims to unlock mysteries about the universe's fundamental nature and matter-antimatter asymmetry by analysing neutrino particles. The experiment involves assembling four giant detectors inside caverns blasted from rock a mile beneath the Black Hills.Why it mattersThe project is being conducted in the former Homestake mine, which for over a century attracted workers searching for gold. The experiment could potentially find answers to the deepest mysterie
