Simons Foundation Lectures are free public colloquia related to basic science and mathematics. These high-level talks are intended for professors, students, postdocs and business professionals, but interested people from the metropolitan area are welcome as well.
Dark matter is a new, mysterious form of matter that holds the universe together. It is responsible for the growth of structures in our universe as large as the Milky Way that can ultimately support life. While we know that dark matter is important for the evolution of our universe, and that it is much more prevalent than ordinary matter (such as electrons and nuclei), the underlying nature of dark matter remains unknown. Still, by using theoretical ideas exploring what dark matter may be, we can search for experimental evidence about its nature.
Kathryn Zurek will review evidence for the presence of dark matter in our universe and the need for a new theory to describe the dark matter sector. She will discuss how dark matter hunters are searching for dark matter through observations on galactic and extra-galactic scales, as well as in terrestrial experiments. She will focus on the connections among these various kinds of searches, from the cosmic microwave background to observations of high-energy gamma rays in our galaxy, as well as terrestrial experiments such as those involving the Large Hadron Collider.
