The most astounding fact is the knowledge that the atoms that comprise life on Earth, the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core, under extreme temperatures and pressure. These stars, when unstable in their later years, collapsed and exploded, scattering their enriched guts across the galaxy, guts made of carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself. These ingredients become part of gas clouds that condense and collapse, forming the next generation of solar systems — stars with orbiting planets — and these planets now have the ingredients for life. So when I look up at the night sky 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.
