Astrophysics and Astronomy | Cosmology, Relativity, and Gravity
Over 95% of the universe is composed of a substance that is not made of baryons (i.e., normal matter), and does not emit any radiation to detect it. James Schombert reviews 1) how we know this dark matter exists, 2) what we know that it isn't, and 3) why it is important to cosmology, the formation and evolution of the universe. This presentation is part of a five-lecture series focusing on different aspects of astronomy and cosmology.
