Can We Build a Neutrino Laser? The Physics World Is Fiercely Debating Whether This Idea Could Be More Than Sci-Fi

🚀 Can we build a #neutrino #laser or is it pure sci-fi?

The AMO #physics community is debating if #superradiant neutrino emission could emerge from #radioactive #ultracold atoms. I unpack idea, criticism, & what might still work 👇
