See it on NASA's siteThis is a dark matter map from a simulated universe. The gravity of unseen dark matter is the leading explanation for why galaxies rotate so fast, why galaxies orbit clusters so fast, and why gravitational lenses strongly deflect light. It also explains why visible matter is distributed as it is in the local universe and on the cosmic microwave background.
