Rationally Speaking #106 - Live From NECSS With Lawrence Krauss

Rationally Speaking returns to NECSS for a live show with Lawrence Krauss, theoretical physicist and author of best selling books like The Physics of Star Trek and A Universe from Nothing. Julia and Massimo chat with Lawrence about whether the laws of the universe demand some kind of explanation, whether string theory should be deemed a failure, and how he ended up featured in a geocentrist documentary.
