At some point science may find God, and then things will really change.  We are accustomed to believing in God based on faith and revelation; the instruments of science, it is said, show no signs of God.  But then again, maybe they do. In his new book, God's Blueprint - Scientific Evidence that Earth was Created for Humans, this week's guest, Christopher Knight, marshals scientific and logical evidence that points in the same direction: the universe and life itself are just too intricately designed to have arisen by chance.  This evidence comes not just from the peculiar fit between humans and cosmos, but also from the ratios among key features of the Earth, the moon, and the sun that keep appearing in completely unrelated areas, all which suggests a deep blueprint we are just starting to uncover.
