Thirteen billion years ago, in the universe's earliest chapters, small reddish galaxies harbored supermassive black holes swaddled in dense gas — and new research suggests these ancient nurseries may be the long-sought origin of the high-energy neutrinos that silently pass through Earth today. The James Webb Space Telescope's discovery of these 'Little Red Dots' has given physicists a plausible answer to a stubborn mismatch: why neutrino signals reach us without the gamma rays that should accompany them. It is a reminder that the cosmos keeps its oldest secrets encoded in the faintest light, a
