Christophe Galfard and Janna Levin will take us on a wonder-filled journey to the surface of our dying sun, shrink us to the size of an atom, and put us in the deathly grip of distant black holes. Our speakers will make us understand the mind-bending science that underpins modern life, from quantum mechanics to Einstein’s theory of general relativity.

In English. Free and open to the public. No RSVP necessary.

WATCH THIS EVENT LIVE ON THURSDAY APRIL 21 AT 7PM (EST)

Christophe Galfard holds a PhD. in theoretical physics from Cambridge University. He is coauthor, with Stephen Hawking and his daughter, of their first YA book, George’s Secret Key to the Universe. In the past few years, he has given talks and written a live show about our universe that has been seen by more than 130,000 people, of all ages and educational backgrounds.

Janna Levin is a professor of physics and astronomy at Barnard College of Columbia University. She is also director of sciences at Pioneer Works, a center for arts and sciences in Brooklyn, and has contributed to an understanding of black holes, the cosmology of extra dimensions, and gravitational waves in the shape of spacetime. Her previous books include How the Universe Got Its Spots and a novel, A Madman Dreams of Turing Machines, which won the PEN/Bingham Prize. She was recently named a Guggenheim fellow. Her new book, Black Hole Blues and Other Songs from Outer Space, is just out with Knopf.
