Chicago Suburbs Harper Lecture: Radically Rethinking Dark Matter Sun., November 11, 2018 | 2:00 PM — 4:00 PM Hyatt Regency Lisle 1400 Corporetum Drive Lisle, IL 60532 United States Featuring Dan Hooper, professor of astronomy and astrophysics The overwhelming majority of cosmologists are confident that most of the matter in our universe is not made up of atoms but rather of a substance known as dark matter. We do not know, however, exactly what dark matter is, how it behaves, or how it was created in the early universe. In this lecture, Dan Hooper will explain why we are so sure that dark matter exists and describe how recent experimental results suggest that it may be very different than we had long imagined.
