Summary
David Kaiser knows the universe is hiding something enormous – and no one can see it. Dark matter appears to be all over our universe, but what is it? As a physicist and science historian, David joins Hakeem to discuss one of astrophysics most impossible puzzles. Nearly a century of observations - from the motion of galaxy clusters to the rotation of individual galaxies to the subtle patterns in the cosmic microwave background - has built a remarkably consistent case that most of the matter in the universe is invisible to us. Kaiser and Hakeem work through how that evidence accumulated, why the leading candidate explanations have become increasingly constrained, and one tantalizing idea that is getting physicists excited.
