Even as an atheist, I understood the challenge offered by the “Standard Cosmological Model” (the Big Bang Theory) when examined from my naturalistic worldview. This model infers a “cosmological singularity” in which all space, time and matter came into existence at a point in the distant past. In others words, “everything” came from “nothing”. I knew this presented a problem for me as a naturalist; if the universe had a beginning, the “principle of causality” inclined me to believe there must have been a cause. But, what could cause something as vast as the universe? Could it have caused itself to come into existence, or must the first cause of all space, time and matter be non-spatial, atemporal and immaterial? How could “everything” come from “nothing”?
One way to navigate this dilemma is simply to redefine the terms we are using. What do we mean when we say “everything” or “nothing”? At first these two terms might seem rather self-explanatory, but it’s important for us to take the time to define the words. By “everything” we mean all space, time and matter. That’s right, space is “something”; empty space is part of “everything” not part of “nothing”. For some of us, that’s an interesting concept that might be hard to grasp, but it’s an important distinction that must be understood. When we say “nothing”, we mean the complete absence of everything; the thorough non-existence of anything at all (including all space time and matter). These two terms, when defined in this way, are consistent with the principles of the Standard Cosmological Model, but demonstrate the dilemma. If everything came from nothing, what caused this to occur? What is the non-spatial, atemporal, immaterial, uncaused, first cause of the universe? A cause of this sort sounds a lot like a supernatural Being, and that’s why I think many naturalists have begun to redefine the terms.
Lawrence Krauss, Arizona State University Professor (School of Earth and Space Exploration and Director of the Origins Initiative) wrote a book entitled, A Universe from Nothing: Why There Is Something Rather than Nothing. As part of the promotion for the book, Krauss appeared on the Colbert Report where he was interviewed by comedian Stephen Colbert. During the interview, Krauss tried to redefine “nothing” to avoid the need for a supernatural first cause:
