Leonard Susskind - Why Black Holes are Astonishing

Leonard Susskind is the Felix Bloch Professor of Theoretical Physics at Stanford University, and Director of the Stanford Institute for Theoretical Physics. In this interview he talks about how black holes warp space and time, squeeze matter to a vanishing point, and trap light so that it cannot escape. Tune in to find out how black holes can perform such stupendous tricks, and what can we learn from them.
