Stargazing Lecture

Trying to Prove Einstein Wrong
Agnès Ferté, Postdoctoral Fellow, Department of Astronomy, 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

Why is the universe's expansion getting faster and faster? Maybe Einstein's theory of gravitation is incorrect for large cosmic distances? It takes hundreds of cosmologists, the most advanced telescopes and instruments, and many hours of numerical computation to answer these questions. I will explain my work taking part in this endeavor as a cosmologist in the Dark Energy Survey, from observing galaxies at a large telescope in Chile to doing intensive computations on supercomputers.

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.
