Stargazing Lecture

Black Holes and Gravitational Waves: Was Einstein Right?
Saul Teukolsky, Robinson Professor of Theoretical Astrophysics, Caltech,

Because this is an online event, the in-person stargazing that normally follows events in this series will not be possible.

Join the YouTube Livestream here:

7:00–7:30 p.m. - Virtual Lecture
7:30–9:00 p.m. - Virtual Panel Q&A and Discussion

The 2017 Nobel Prize in Physics went to the founders of the LIGO experiment for the detection of gravitational waves from a pair of orbiting black holes. This is one of the most exciting scientific discoveries of the past fifty years. What are gravitational waves and how were they detected? How have Caltech researchers used supercomputers to establish that the waves did in fact come from black holes? How does this experiment confirm that space and time are distorted by strong gravity, just as Einstein predicted? And what exciting discoveries might be just around the corner?

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 90 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.
