“The most astounding fact, is the knowledge that the atoms that comprised life on earth, the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements under extreme temperatures and pressure. These stars, the high mass ones among them, went unstable in their later years. They collapsed and then 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, collapse, form the next generation of solar systems, stars with orbiting planets. And those planets now have ingredients for life. 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.” – Neil deGrasse Tyson
