WLC Quotes John Barrow and Frank Tipler

If you’ve watched many William Lane Craig debates (such as this one from 2009), you’ve probably heard him use the following quote from cosmologists Barrow and Tipler while defending his Kalam Cosmological Argument:

At this singularity, space and time came into existence; literally nothing existed before the singularity, so, if the Universe originated at such a singularity, we would truly have a creation ex nihilo.

– John Barrow & Frank Tipler, The Anthropic Cosmological Principle (1986), page 442

(Note for the non-Latin speakers: ex nihilo translates to “out of nothing.”)

In the clip linked above, Dr. Craig specifically claims that this Barrow and Tipler quote represents “contemporary cosmology” – never mind that the book it was taken from is nearly 25-years-old.  But in reality,  a lot has happened in the last 25 years in regard to the initial (Big Bang) singularity.

Remember: Barrow and Tipler’s claim that the universe came from “literally nothing” depends on whether or not there was an initial singularity (“if the Universe originated at such a singularity…”). Athough, I’d argue that Barrow and Tipler’s definition of “nothing” is not the same as Dr. Craig’s definition of “nothing,” but I’ll save that for another post (or you can watch my video on this quote).

So, was there an initial singularity at the Big Bang? Barrow and Tipler seemed to think so in 1986.  But in 1988, Stephen Hawking (commenting on his singularity work with Roger Penrose) wrote in A Brief History of Time (page 50):

It is perhaps ironic that, having changed my mind, I am now trying to convince other physicists that there was in fact no singularity at the beginning of the universe—as we shall see later, it can disappear once quantum effects are taken into account

And the tide has shifted against the singularity ever since. As theoretical astrophysicist Ethan Siegel explained in 2010,

…the idea that our Universe started from a singularity was a very good one back when we thought that the only important things in our Universe were matter and radiation, but now that we know about inflation, there is no reason to believe that our Universe ever had a singularity in the past.

He goes on to say that the initial singularity is an “outdated idea.”

    Have you considered Hawking’s 2008 lecture where he affirms the singularity?

      Well, first that lecture is from 1996… not 2008. Second, he doesn’t affirm the singularity. He instead is explaining his no-boundary model where the singularity disappears when imaginary numbers (multiples of the square root of -1) are used. I wrote about this here: https://debunkingwlc.wordpress.com/2010/10/24/stephen-hawkings-model-of-cosmic-origins/

        When IMAGINARY numbers are used; in other words, they don’t exist in REALITY, which is what we are really in. Unless you deny reality itself. I’m sure you know what an imaginary number is, so you know that it is technically an impossible value. Because Hawking had to use a more or less made up value, it just proves that his theory doesn’t hold water.

    I have heard Tipler argue that Hawking ideas are not tested so moot.Only tested ideas are valid.

    Thats the point imaginary numbers dont exist in the real world. You can make whatever you want into what you want it if you plug in the right numbers as they did. The equation doesnt exist in real life.
