The greatest cosmological discoveries - the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Astrophysicist Priyamvada Natarajan creates maps of the invisible matter in the universe. She explains the science behind this but also provides an understanding of how radical scientific theories gain acceptance. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes - these are some of the puzzling cosmological topics of the early twenty-first century. Priyamvada Natarajan is a professor of physics and astronomy at Yale University.
