US scientists unveil concept for ‘world’s first neutrino laser’ to unlock breakthroughs

SMRTR summary

MIT researchers propose creating the world's first neutrino laser using ultra-cold radioactive rubidium atoms in a quantum state that would decay synchronously to produce intense, controlled neutrino beams. This revolutionary concept could enable breakthrough studies of mysterious "ghost particles," enable communication through Earth's core, and generate medical isotopes, though significant technical challenges remain before experimental demonstration becomes possible.
