8:00–8:30 p.m. - Public Lecture
8:30–9:45 p.m. - Panel Q&A and Guided Stargazing

Gravity on Earth is quite boring: it makes apples fall. However, near a black hole things get really strange. Time slows down and everything becomes spaghetti. Can we abuse gravity to achieve time travel or to visit distant galaxies? What is preventing us from turning science fiction into science fact? Come learn about the wild and whacky side of gravity and how black holes are too weird even for Hollywood sci-fi movies like Interstellar.

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.
