This laser would shoot beams of neutrinos, not light

Scientists have proposed a groundbreaking concept to create neutrino lasers using superradiance, a quantum phenomenon that could make previously "impossible" neutrino beams a reality. By using radioactive Bose-Einstein condensates made of rubidium-83, researchers could dramatically accelerate decay processes to produce synchronized neutrino emissions, potentially enabling tabletop experiments that would free scientists from reliance on massive particle accelerators for neutrino research.
