Physicist Stephen Hawking got the world’s attention a long time ago.  The brilliant scientist, trapped in wheel chair and Lou Gehrig’s disease, whose mind encompassed the cosmos.

In “A Brief History of Time”, Hawking laid out what we knew of the universe in compelling imagery and metaphor.

Now he’s back, with physicist Leonard Mlodinow, for a cosmic update.  Not one universe out there, but many, they say.  And no need now for God to explain the origin of everything.  Science, they say, will do it.

Guest:
