Dunlap Institute: Cosmos From Your Couch - What Dark Matter Isn’t (ONLINE)

Eighty-five percent of the matter in our universe is made up of a mysterious invisible substance scientists call “dark matter.” Although we know some of its basic properties, we have no idea what dark matter actually is, or how it relates to the regular matter we know and love. What is this strange substance, and how can we find out? In this talk Harrison Winch will introduce some of the many theories proposed to explain dark matter, and demonstrate how astrophysicists work to constrain or “rule out” some of these theories. This approach stems from the importance of falsifiability in science, and he will explain how this philosophy of falsifiability guides current dark matter research. By the end of the talk, he hopes to convince you that the important question to ask is not “what dark matter is,” but “what dark matter isn’t.”
