Internationally known theoretical physicist and bestselling author Lawrence Krauss offers provocative, revelatory answers to the most basic philosophical questions: Where did our universe come from? Why is there something rather than nothing? And how is it all going to end? Why is there something rather than nothing?" is asked of anyone who says there is no God. Yet this is not so much a philosophical or religious question as it is a question about the natural world-and until now there has not been a satisfying scientific answer. Today, exciting scientific advances provide new insight into this cosmological mystery: Not only can something arise from nothing, something will always arise from nothing. A mind-bending trip back to the beginning of the beginning, A Universe from Nothing authoritatively presents the most recent evidence that explains how our universe evolved-and the implications for how it's going to end. It will provoke, challenge, and delight readers to look at the most basic underpinnings of existence in a whole new way. As Richard Dawkins has described it: This could potentially be the most important scientific book with implications for atheism since Darwin.
