Our guest this week needs no introduction for those in the skeptical and secular world. After all, he has a frakkin' asteroid named after him.

He’s Phil Plait—science blogger extraordinaire for Discover Blogs, where he authors “Bad Astronomy.” Recently, Plait joined Point of Inquiry for a wide ranging conversation about standing eggs on end, Apollo moon landing deniers, wacky yet endearing Hollywood bad science, something called “spaghettification”….and the end of the world.

Phil Plait is a skeptic and an astronomer, and former president of the James Randi Educational Foundation. He lectures widely across the country and is the author of two books, most recently Death from the Skies: These Are the Ways the World Will End.
