MIT Research Determines Neutrino Laser is Fundamentally Impossible

Physicists at MIT, led by Wolfgang Ketterle, have concluded that creating a coherent, laser-like beam of neutrinos is physically impossible. Their analysis, published in Physical Review Letters, indicates that the extreme recoil from neutrino emission and their fermionic nature prevent the necessary quantum coherence and amplification within a Bose-Einstein condensate. This finding refutes a previous proposal for such a device.
