Life. Some scientists are searching the cosmos for habitable cradles of it, others are combing Earth for exotic forms of it, while others still are on the verge of creating it in the lab. The forms life could take seem endless — at least in theory. But are there universal laws of life, much like the fundamental laws of physics, which govern or limit the characteristics that make it — in any form — possible? Our audience joined John Hockenberry for a vibrant discussion with leading astrobiologists Paul Davies, Steven Benner and Maggie Turnbull as they looked at life through the lens of chemistry and physics in search of life as we don’t know it.
