"Everything" may never be the same again

The asymmetry in the cosmic microwave background is generating some buzz about the possibility of a multiverse. Here's a recent Minute Physics explanation of the main theories out there, followed by several recent (longer) discussions with scientists and others on the question.



In March, Neil deGrasse Tyson moderated the 2013 Isaac Asimov Debate on "The Existence of Nothing" with physicists Lawrence Krauss (Arizona State University), Eve Silverstein (Stanford), and J. Richard Gott (Princeton) and journalists Charles Seife and Jim Holt in which Gott shows a physical model of a multiverse.



Then in June, John Hockenberry hosted a discussion between cosmologists and physicists Andreas Albrecht, Alan Guth, Andrei Linde, and Neil Turok.



Update (July 2, 2013): And cosmologist Sean Carroll just posted this recent interview that he did with Jim Holt on "Why Does The World Exist?"


 
And if you made it through all that, you will know what I mean when I say that Richard Feynman had the best response to Jim Holt's complaining. You might also be interested in Victor Stenger's 'The Comprehensible Cosmos' for a physicists take on where the "laws of physics" came from (spoiler alert: It's us!).
