A strange galaxy 72 million light-years away seems to be missing its dark matter – Yahoo News

Scientists have actually validated the discovery of an unusual galaxy 72 million light-years from Earth that appears to be missing its dark matter.Why it matters: Its long been believed that dark matter– the undetectable stuff that comprises much of matter in the universe– is an essential active ingredient for galaxies, however the discovery complicates that picture.Stay on top of the newest market patterns and financial insights with Axios Markets.
