“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 pressures. 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 out of carbon, nitrogen, oxygen and all the fundamental ingredients of life itself… So that 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 because they’re small and the universe is big. But I feel big because my atoms came from those stars.” –Neil deGrasse Tyson ...
