Alex Vilenkin on the Beginning of the Universe, Part 2

In my last post I mentioned that I have been reading Alex Vilenkin's book, Many Worlds in One: The Search for Other Universes (New York: Hill and Wang, 2006). I also mentioned that I was trying to understand Vilenkin's explanation of the theorem he developed with Arvind Borde and Alan Guth.
