This interview with Michio Kaku is long, but . . . wow! It's kind of like the next step past Hawking in popularizing esoteric science, with the added fun that all sorts of stuff gets tossed in, too - time travel, politics, the Theory of Everything, and the chance that I will, in the next nanosecond, find myself choking out my life on the surface of a different planet (hint: since it would probably occur longer than the life of the Universe, I'm not using sleep over it). He's a terribly exciting speaker.
Make the time - three hours. It will be worth it.
