So when I look up at the night sky and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up, many people feel small - 'cause they're small and the Universe is big - but I feel big because my atoms came from those stars.
