Why is there something rather than nothing? Mind boggling to think about. Krauss explains current thinking about the origin and future of the universe and why it looks like it does. He makes for clear explanations, but I'm sure I couldn't explain it to anyone else without a ton of handwaving; I'm a poor vessel for all the details. Still, what he does make clear is how all the theories and research add up to a coherent, if complete, picture of the universe. Would make good re-reading.
