TED: The search for the invisible matter that shapes the universe | Chanda Prescod-Weinstein
The universe that we know, with its luminous stars and orbiting planets, is largely made up of elements we can't actually see -- like dark energy and dark matter -- and therefore don't fully understand. Theoretical physicist Chanda...
