Futurist Michio Kaku says sooner or later humanity will face the possibility of extinction, and it’s up to scientists to come up with a plan B whether it’s another planet or even another galaxy.  He explains why it’s important for us to return to the moon, how we would go about terraforming Mars, and what he calls the new "gold rush" that could fund NASA indefinitely.  He shares his theory on why we haven’t encountered alien life and where humans fit in on his hierarchy of civilizations.  Michio Kaku describes the three ways the universe will almost certainly die, but says in the meantime immortality might be just around the corner.  Plus he gives me a progress update on what he calls his life’s work proving Einstein’s Unified Theory of Everything.
