Funny thing about PopSci stuff. Doesn't matter how many PopSci books you've read - every next one brings something more

because depths of ignorance of PopSci reader (me) are unmeasurable.

BTW, read up about inflation theory Krauss mentioned. I listened to one talk by Lande - pure awesomeness. And it's new.
