Where did the universe come from? What was there before it? What will the future bring? And finally, why is there something rather than nothing? Krauss answers to these and other timeless questions in a wildly popular lecture on YouTube have attracted almost a million viewers. The last of these questions in particular has been at the center of religious and philosophical debates about the existence of God, and its the supposed counterargument to anyone who questions the need for God. Scientists have, however, historically focused on more pressing issuessuch as figuring out how the universe actually functions, which could help us to improve our quality of life. In this cosmological story that rivets as it enlightens, pioneering theoretical physicist Lawrence Krauss explains groundbreaking scientific advances that turn the most basic philosophical questions on their head. One of the few prominent scientists to have actively crossed the chasm between science and popular culture, Krauss reveals that modern science is indeed addressing the question of why there is something rather than nothingwith surprising and fascinating results. The beautiful experimental observations and mindbending theories are all described accessibly, and they suggest that not only can something arise from nothing, something will always arise from nothing. With his characteristic wry humor and clear explanations, Krauss takes us back to the beginning of the beginning, presenting recent evidence for how our universe evolvedand the implications for how it will end. It will provoke, challenge, and delight readers as it looks at the most basic underpinnings of existence in a whole new way. And this knowledge that our universe will be quite different in the future has profound consequences and directly affects how we live in the present. As Richard Dawkins described it, this could potentially be the most important scientific book with implications for supernaturalism since Darwin.
