Cosmologist Lawrence Krauss: 'A Universe from Nothing'
January 4, 2013
[REBROADCAST] How did the Universe arise from nothing? And what was there before? ¬†Those are the kinds of questions that for most of us set our heads spinning — not so for renowned cosmologist LAWRENCE KRAUSS. ¬†Krauss says that human beings have been contemplating the workings of the universe for millennia but only in recent years, with scientific advances, have we finally been able to get some answers. ¬†Krauss lays them out in his recent book, "A Universe from Nothing: Why There is Something Rather than Nothing," which is out in paperback.
