“What is it that you contain? The dead. Time. Light patterns of millennia opening in your gut. Every minute, in each of you, a few million potassium atoms succumb to radioactive decay. The energy that powers these tiny atomic events has been locked inside potassium atoms ever since a star-sized bomb exploded nothing into being. Potassium, like uranium and radium, is a long-lived radioactive nuclear waste of the supernova bang that accounts for you.Your first parent was a star.”

“What is it that you contain?The Dead. Time. Light patterns of millennia. The expanding universe opening in your gut. Are your twenty-three feet of intestines loaded with stars?”

“Atoms, in short, are very abundant. They are also fantastically durable. Because they are so long lived, atoms really get around. Every atom you possess has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you. We are each so atomically numerous and so vigorously recycled at death that a significant number of our atoms-- up to a billion for each of us, it has been suggested-- probably once belonged to Shakespeare.”

“every atom in your body came from a star that exploded. and, the atoms in your left hand probably came from a different star than your right hand. it really is the most poetic thing i know about physics: you are all stardust.”

“The amazing thing is that every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.”

“Every atom you possess has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you. We are each so atomically numerous and so vigorously recycled at death that a significant number of our atoms - up to a billion for each of us, it has been suggested - probably once belonged to Shakespeare. A billion more each came from Buddha and Genghis Khan and Beethoven, and any other historical figure you care to name. So we are all reincarnations - though short-lived ones. When we die, our atoms will disassemble and move off to find new uses elsewhere - as part of a leaf or other human being or drop of dew.”
