Dark matter might leave a telltale ‘fingerprint’ on light, scientists say
SMRTR summary
University of York scientists propose that dark matter, which makes up 27% of the universe but has never been directly observed, could leave detectable red or blue "fingerprints" on starlight passing through it. This theoretical breakthrough challenges assumptions that dark matter never interacts with light and could help astronomers identify dark matter's composition using next-generation telescopes.
