Over the past few decades, scientists have made incredible discoveries about how our cosmos evolved over the past 13.8 billion years. But we still know very little about what happened in the first seconds after the Big Bang. In this public lecture, physicist and author Dan Hooper explores this critical gap in our scientific knowledge. He examines how physicists are using the Large Hadron Collider and other experiments to re-create the conditions of the Big Bang and to address mysteries such as how our universe came to contain so much matter and so little antimatter. Could these tools enable us to discover the nature of dark matter and how it was formed in our universe’s first moments? Can we lift the veil on the era of cosmic inflation, which led to the creation of our world as we know it?

Dan Hooper is a senior scientist and the head of the Theoretical Astrophysics Group at Fermilab and a professor of astronomy and astrophysics at the University of Chicago. His research focuses on the interface between particle physics and cosmology, and he is especially interested in questions about dark matter and the early universe. He is the author of three books, including “At the Edge of Time.”
