Heavy invisible neutrinos could leave a pattern on the celestial map of ancient light. A chemical asymmetry during the Big Bang amplifies their signal—like a whisper turned into a shout by a bullhorn. The discovery promises to crack open the door to physics hidden beyond known laws.
🎯 The seesaw effect links the mass of ordinary neutrinos with superheavy twins: the more massive the heavy partner, the lighter our neutrino.
