On Sean Carroll. . . .
Atheist laymen routinely misconstrue the observations made by classical theists who are in fact steeped in the pertinent science. They typically do this for two reasons: (1) they don't know the science themselves and the varying contexts and language thereof; (2) they blindly rely on the interpretations of proofs tendered by atheist scientists whose worldview is predicated on metaphysical naturalism. Additionally, there are a handful of atheist physicists who are especially hostile to theistic belief, and dishonestly imply or arrogantly assume in debate that theist apologists fail to agree with the philosophically dogmatic and obtuse expectations of metaphysical naturalism because they don't understand the science. These same atheist physicists occasionally engage in cheap antics or ascribe ungenerous interpretations to theists' observations. Of course, there are atheist laymen, who, like me, have studied the pertinent science as well, but in my experience most of them are no more conscious of their metaphysical biases than the sheep. In the meantime, learned classical theists are continuously conscious of the disparate metaphysical presuppositions that underlie, respectively, each camp's worldview.
The Carroll-Craig Debate at the Greer-Heard Forum (2014):
In recent years, the camps have clashed over Borde-Guth-Vilenkin's theoretical purview, which is not strictly limited to the cosmological models of classical spacetime as physicist Sean Carroll (yes, the Carroll of the ill-conceived Carroll-Chen model) seemed to suggest in 2014 at the Greer-Heard Forum, where he debated William Lane Craig. In the debate, Carroll states:
So I’d like to talk about the Borde-Guth-Vilenkin theorem since Dr. Craig emphasizes it. The rough translation is that in some universes, not all, the space-time description that we have as a classical space-time breaks down at some point in the past. Where Dr. Craig says that the Borde-Guth-Vilenkin theorem implies the universe had a beginning, that is false. That is not what it says. What it says is that our ability to describe the universe classically, that is to say, not including the effects of quantum mechanics, gives out. That may be because there's a beginning or it may be because the universe is eternal, either because the assumptions of the theorem were violated or because quantum mechanics becomes important.
This is all rather slippery of Carroll, as Craig didn't argue that Borde-Guth-Vilenkin asserts an absolute beginning of the cosmos in the sense that Carroll means. Also, his description of the theorem is less than forthright. We expect this sort of equivocation between combatants in a political debate, but in a forum such as this we have every right to expect that the interlocutors will relate the science as accurately as possible and, in good faith, alert the audience to the exact nature of the caveats, not simply vie to win points with rhetorical devices that leave the wrong impression about the science itself in the minds of the audience. From the scientific literature in general, there is absolutely no good reason to doubt that the universe (our metagalaxy or spacetime) in which "we live and move and have our being" began to exist at a point of time in the finite past! And the Borde-Guth-Vilenkin theorem is the exclamation mark, as it were, at the end of the previous sentence.
Then Craig goes on to show why putatively eternal, cosmological models must necessarily have either a geometric or a thermodynamic beginning. Craig does not base the entirety of his argument on Borde-Guth-Vilenkin! The fact of the matter is that Carroll did not directly refute any of this! Why? Because, sans an entirely new and unknown scheme of physics such that everything we think we know from general relativity and quantum mechanics is tossed into the trash bin, the findings of the proofs cited by Craig
in toto are incontrovertible. Rather, what Borde-Guth-Vilenkin doesn't say is that our universe is necessarily the one and only to have ever existed, for while the theorem and others rule out most of the cyclic cosmogonies that entail an epoch of contraction prior to expansion, it doesn't rule out all of them, such as the thermodynamic-time-reversal models of Aguirre-Gratton and Carroll-Chen for which no natural mechanism can be given for their low-entropy state at the bounce.
Guess what else is doesn't say. . . . It doesn't say—despite what Dr. Carroll implies, if I may be so impertinent—that the universe might be or could be eternal! How could it? And despite of what the materialist Carroll seems to believe, in vain, a theory of quantum gravity is not going to yield a proof that the universe is eternal either, even if it did somehow provide a natural mechanism for the initial state of low-entropy for either direction of thermodynamic time ( ∞- ←
t → +∞ ). That's the ultimate injunction of Wall (2013). Carroll's dream theory would merely nail down a material cause for the initial state, and I'm not even sure that such an animal is a coherent expectation. In any event, we would then want to know what the natural mechanism is that accounts for the quantum mechanism and so on ad infinitum. Again, a contingent entity of causality cannot account for its own existence, and the answer to the question of why something exists rather than nothing is beyond the ken of science.
(Likewise, learned theist apologists are fully aware of the fact that it may not be possible to scientifically demonstrate beyond all doubt that the material realm of being had an absolute geometric beginning out of no previously existing material substance—whether it be a single universe, a multiverse or a cyclic configuration. Hence, theists are certainly not arguing that the preponderance of scientific evidence absolutely proves God's existence as such, but since 1931 the evidential noose has gotten tighter and tighter. Indeed, unlike most atheists, theists understand the limits of scientific inquiry. It is the first principles of ontology per the imperatives of logic propounded by the philosophical KCA, for example, that prove God's necessity and put the burden of proof on the atheist to provide a coherent account for how actual infinities could exist or how existence could arise from nonexistence. The scientific KCA is a probability argument of the most likely case and the best explanation for that case. In fact, the reason the typical atheist confounds the actualities of the scientific KCA is precisely because he doesn't grasp the limitations of scientific inquiry, because he's willing to be mislead by scientific "authorities" who affirm his biases and because he's mired past his eyeballs in metaphysical naturalism. It's all nonsense, of course, the stuff of "atheists in the gaps" projecting their thought processes on theists, whereby they impulsively leap over the potentially real and numerous cosmological histories that might obtain and land on the either-or option of ultimate origin. In other words, there's no "beginning and middle" in their calculus. They don't regard the feasibility of the various cosmological histories. They don't weigh the statistical probabilities relative to the preponderance of the rational and empirical evidence. All they hear is a bald
God did it! opposing their evidentially vacuous
The cosmos did it! )
