A consequence of general relativity is that massive objects bend light, which enables scientists to see the invisible. Lecture: 03:10; Lecture Q&A: 27:58; Panel Q&A: 33:44 Date: November 17, 2017 Lecturer: Denise Schmitz Title: Cosmic Lenses: Bending Light with Gravity Abstract: One important consequence of Einstein's theory of relativity is that massive objects can bend light, an effect known as "gravitational lensing." Over the years, astronomers have learned to take advantage of this intriguing phenomenon to learn about everything from black holes to dark matter to galaxy clusters. In this lecture, I'll demystify the science behind gravitational lensing and take you on a tour of the amazing breakthroughs it has enabled.
