Today instead of writing a post I decided to finally get around to watching the lecture by lawrence Krauss "A universe from nothing". I know I'm a bit late to the party here, most people reading this have probably watched it already, but if you haven't it's enjoyable and I definitely recommend checking it out.
As I was watching I made some notes of spots I thought were interesting, or things I might want to reference again later. Enjoy
