8:00–8:45 p.m. - Public Lecture
8:45–9:45 p.m. - Panel Q&A and Guided Stargazing

Scientists believe that most of the mass of the universe is composed of dark matter, a hypothetical material with no (or extremely weak) interactions with the normal matter we encounter in our daily lives. Despite being effectively invisible, dark matter is essential for the formation of large structures, like galaxies, in the universe. The fundamental nature of dark matter is one of the biggest question in modern physics. Could it be black holes? Could it be some new particles that have so far eluded detection in collider experiments? In this talk, I will discuss the compelling evidence for dark matter from astrophysical observations and introduce several hypotheses about the true nature of dark matter.

About the Series

Stargazing Lectures are free lectures at a public level followed by a Q&A panel and guided stargazing with telescopes (weather permitting). All events are held at the Cahill Center for Astronomy and Astrophysics at Caltech. No reservations are needed. Lectures are 30 minutes; stargazing and panel Q&A last 60 minutes. Stay only as long as you want.

Stargazing is only possible with clear skies, but the lecture and panel Q&A takes place regardless of weather.
