Kavli Foundation: SPOTLIGHT LIVE -- Falling into a Black Hole

3:00pm to 3:50pm

The Kavli Foundation -- SPOTLIGHT LIVE
September 25 Noon-12:50 pm PDT  
"Falling into a Black Hole"

 
Ask Your Questions of Raphael Bousso, Juan Maldacena, Joseph Polchinski and Leonard Susskind    
 
WHAT HAPPENS WHEN YOU FALL INTO A BLACK HOLE, the mysterious remnant of a dead star whose gravity is so strong that not even light can escape? According to Einstein's theory of general relativity, the fall would be uneventful, until at some point the force of gravity would rip you apart. But a new theory suggests a different fate - and if correct, could challenge our understanding of gravity and how the universe works.
 
On Sept. 25, Noon-12:50 pm PDT, four theoretical physicists - Raphael Bousso (U.C. Berkeley), Juan Maldacena (Institute for Advanced Study), Joseph Polchinski (U.C. Santa Barbara) and Leonard Susskind (Stanford University) - will answer your questions about the latest theories about what happens when matter falls into a black hole and how these ideas are prompting researchers to reconsider our understanding of gravity.
 
About the participants:
RAPHAEL BOUSSO - Professor of Physics at the University of California, Berkeley, Dr. Bousso is recognized for discovering the general relation between the curved geometry of space-time and its information content, known as the "covariant entropy bound." This allowed for a precise and general formulation of the holographic principle, which is believed to underlie the unification of quantum theory and Einstein's theory of gravity. Dr. Bousso is also one of the discoverers of the landscape of string theory, which explains the small but non-vanishing value of the cosmological constant (or "dark energy"). His work has led to a novel view of cosmology, the multiverse of string theory.

JUAN MALDACENA - Professor of Theoretical Physics at the Institute for Advanced Study in Princeton, New Jersey. Dr. Maldacena's work focuses on quantum gravity, string theory, and quantum field theory. He has proposed a relationship between quantum gravity and quantum field theories that elucidates various aspects of both theories. He is studying this relationship further in order to understand the deep connection between black holes and quantum field theories, and he is also exploring the connection between string theory and cosmology.   

JOSEPH POLCHINSKI - Professor of Physics at the University of California, Santa Barbara and a Permanent Member of the Kavli Institute for Theoretical Physics at UCSB. Dr. Polchinski's contributions to theoretical physics include his discovery of D-branes, extended structures that appear to be central to the mathematics and physics of string theory. He is also the author of a widely used two-volume text on string theory.

LEONARD SUSSKIND - Felix Bloch Professor of Theoretical Physics at Stanford University, Director of the Stanford Institute for Theoretical Physics, and Associate Member of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford and SLAC. Dr. Susskind is regarded as one of the fathers of string theory, which attempts to describe the physics of the universe under a single mathematical framework. His current research interests include particle physics, quantum field theory, quantum gravity, black holes, string theory, and cosmology. Dr. Susskind has won both the Boris Pregel Award from the New York Academy of Sciences and the J.J. Sakurai Prize in Theoretical Particle Physics from the American Physical Society. He is also the author of popular science books on physics - among them "The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics," published in 2008.  

BRUCE LIEBERMAN - Freelance science writer and moderator, Lieberman has more than 20 years of experience in the news business. He worked as a reporter at daily newspapers for many years before becoming an independent writer and editor in 2010. For The Kavli Foundation, he has interviewed researchers about numerous topics in astronomy & astrophysics, neuroscience and nanotechnology. He has also written for Scientific American, Smithsonian Air & Space and Sky & Telescope magazines, and other media outlets about a variety of science topics.
