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

Scientists have actually validated the discovery of a strange galaxy 72 million light-years from Earth that appears to be missing its dark matter.Why it matters: Its long been thought that dark matter– the undetectable stuff that comprises much of matter in the universe– is a crucial component for galaxies, however the discovery makes complex that picture.Stay on top of the most recent market trends and financial insights with Axios Markets.
