The question "Why is there something rather than nothing?" has been asked for millennia by people who argue for a creator of our universe. Taking a trip back to the beginning of the beginning and the end of the end—and reviewing the remarkable developments in cosmology and particle physics over the past 40 years that have revolutionized our picture of the universe—Lawrence M. Krauss explores the discoveries that have revolutionized our understanding of both nothing and something. It has become clear that not only can our universe naturally arise from nothing, without supernatural shenanigans, but that it probably did.
