Lawrence Krauss: Every Atom in Your Body Comes From a Star

Lawrence Maxwell Krauss, author of the best-selling book The Physics of Star Trek, is a theoretical physicist and Professor of Physics at Arizona State University. His research focuses on the beginning and the end of the universe.

This past January, Krauss attended the World Economic Forum in Davos and was asked by 99 Faces TV to talk about his work. In a relatively short 381 seconds, he speaks about the scale of the universe, the concept of dark energy and explains how “you really are stardust.” That is to say, every little atom in your body comes from a supernova (or exploding star). Krauss elaborates on this poetic thought in this 2009 video (definitely recommended), and he’ll have more to say in his forthcoming book, A Universe from Nothing.

By profession, Matthias Rascher teaches English and History at a High School in northern Bavaria, Germany. In his free time he scours the web for good links and posts the best finds on Twitter.
