A careful 30% excerpt from the preface from Lawrence Kraus’s January 2012 book A Universe From Nothing:
…I am not sympathetic to the conviction that creation requires a creator, which is at the basis of all of the world’s religions. Every day beautiful and miraculous objects suddenly appear, from snowflakes on a cold winter morning to vibrant rainbows after a late-afternoon summer shower. Yet no one but the most ardent fundamentalists would suggest that each and every such object is lovingly and painstakingly and, most important, purposefully created by a divine intelligence…
Ultimately, many thoughtful people are driven to the apparent need for First Cause, as Plato, Aquinas, or the modern Roman Catholic Church might put it, and thereby to suppose some divine being: a creator of all that there is, and all that there ever will be, someone or something eternal and everywhere.
Nevertheless, the declaration of a First Cause still leaves open the question, “Who created the creator?” After all, what is the difference between arguing in favor of an eternally existing creator versus an eternally existing universe without one?..
The universe is the way it is, whether we like it or not. The existence or nonexistence of a creator is independent of our desires. A world without God or purpose may seem harsh or pointless, but that alone doesn’t require God to actually exist.
For more than two thousand years, the question, “Why is there something rather than nothing?” has been presented as a challenge to the proposition that our universe—which contains the vast complex of stars, galaxies, humans, and who knows what else—might have arisen without design, intent, or purpose. While this is usually framed as a philosophical or religious question, it is first and foremost a question about the natural world, and so the appropriate place to try and resolve it, first and foremost, is with science…
Before going further, I want to devote a few words to the notion of “nothing”—a topic that I will return to at some length later. For I have learned that, when discussing this question in public forums, nothing upsets the philosophers and theologians who disagree with me more than the notion that I, as a scientist, do not truly understand “nothing.” (I am tempted to retort here that theologians are experts at nothing.)
“Nothing,” they insist, is not any of the things I discuss. Nothing is “nonbeing,” in some vague and ill-defined sense. This reminds me of my own efforts to define “intelligent design” when I first began debating with creationists, of which, it became clear, there is no clear definition, except to say what it isn’t. “Intelligent design” is simply a unifying umbrella for opposing evolution. Similarly, some philosophers and many theologians define and redefine “nothing” as not being any of the versions of nothing that scientists currently describe.
But therein, in my opinion, lies the intellectual bankruptcy of much of theology and some of modern philosophy. For surely “nothing” is every bit as physical as “something,” especially if it is to be defined as the “absence of something.” It then behooves us to understand precisely the physical nature of both these quantities. And without science, any definition is just words…
…cience is changing the playing field in ways that make people uncomfortable. Of course, that is one of the purposes of science (one might have said “natural philosophy” in Socratic times). Lack of comfort means we are on the threshold of new insights. Surely, invoking “God” to avoid difficult questions of “how” is merely intellectually lazy. After all, if there were no potential for creation, then God couldn’t have created anything. It would be semantic hocus-pocus to assert that the potentially infinite regression is avoided because God exists outside nature and, therefore, the “potential” for existence itself is not a part of the nothingness from which existence arose.
…When it comes to understanding how our universe evolves, religion and theology have been at best irrelevant. They often muddy the waters, for example, by focusing on questions of nothingness without providing any definition of the term based on empirical evidence…
Science has been effective at furthering our understanding of nature because the scientific ethos is based on three key principles: (1) follow the evidence wherever it leads; (2) if one has a theory, one needs to be willing to try to prove it wrong as much as one tries to prove that it is right; (3) the ultimate arbiter of truth is experiment, not the comfort one derives from one’s a priori beliefs, nor the beauty or elegance one ascribes to one’s theoretical models.
…The tapestry that science weaves in describing the evolution of our universe is far richer and far more fascinating than any revelatory images or imaginative stories that humans have concocted. Nature comes up with surprises that far exceed those that the human imagination can generate.

The true inspiration for this book comes not so much from a desire to dispel myths or attack beliefs, as from my desire to celebrate knowledge and, along with it, the absolutely surprising and fascinating universe that ours has turned out to be.
The direct genesis of this book hearkens back to October of 2009, when I delivered a lecture in Los Angeles with the same title. Much to my surprise, the YouTube video of the lecture, made available by the Richard Dawkins Foundation, has since become something of a sensation, with nearly a million viewings as of this writing, and numerous copies of parts of it being used by both the atheist and theist communities in their debates…
