Larry King’s exclusive conversation with Stephen Hawking

Stephen Hawking – one of the world’s most brilliant thinkers, and a man who rarely gives interviews – joins Larry to discuss the greatest issues facing the planet, where artificial intelligence is headed (and what he makes of Kurzweil’s singularity theory), and what still mystifies him about the universe. Plus, astrophysicist Garik Israelian on creating the Starmus Festival, which celebrates the intersection of science and art and is this year dedicated to Hawking.
