" I don’t make any claims to answer any questions that science cannot answer, and I have tried very carefully within the text to define what I mean by “nothing” and “something.” If those definitions differ from those you would like to adopt, so be it. Write your own book. But don’t discount the remarkable human adventure that is modern science because it doesn’t console you. "

― Lawrence M. Krauss , A Universe from Nothing: Why There Is Something Rather Than Nothing
