The astounding New York Times bestseller�updated with an explanation of the Higgs Boson and its implications�that offers new answers to the most basic philosophical questions: Where did the universe come from and what is the meaning of its origins for our lives today?What came before the universe? Why is there something rather than nothing? These questions have been at the center of religious and philosophical debates about the existence of God, even though they are essentially scientific questions about how the universe actually functions. With wry humor and wonderfully clear explanations, Krauss takes us back to the beginning of the beginning, presenting the most recent evidence for how our universe evolved�and how it�s likely to end. This knowledge that our universe will be quite different in the future has profound implications and directly affects how we live�or should live�in the present. A Universe from Nothing is a provocative, game-changing entry into the debate about the existence of God and why everything exists.
