Scientists at Fermilab aim to solve the mysteries of dark matter, the mysterious stuff that makes up 25% of our universe. In this recording of a live virtual event, eight scientists explain how their research helps answer questions about dark matter. They give tours of their experiments and show some of the cutting-edge work that takes place at lab. The list of speakers and topics is below. This virtual event was recorded on Oct. 31, 2020 and was part of the worldwide Dark Matter Day, organized by the Interactions collaboration.
