The Big Bang, Quantum Field Theory, and God
Surprisingly little difference between QCD and a grown-up version of God
This post explores an argument developed more fully in my evolving book-length essay,* Worlds of Awareness. *It draws on material from the chapters on emergence and the limits of physicalism. The full essay is available at 137fsc.net
In the beginning, there was a quark-gluon plasma.
That’s the standard cosmological story, and it’s extraordinarily well supported. In the first microseconds after the Big Bang, the universe was an undifferentiated soup of quarks and gluons at temperatures so extreme that no composite particles could form. Then, as the universe cooled, something happened: quarks confined into hadrons — protons, neutrons — and the material universe as we know it began to take shape.
This transition is treated as settled physics, and in one sense it is. We can describe what happened. We can model it mathematically. What we cannot do — and this is the point that rarely gets examined — is explain it without making a remarkable metaphysical commitment that most physicists don’t notice themselves making.
The Hidden Metaphysics of “Lawful” Emergence
The standard account says hadron formation was lawful — governed by quantum chromodynamics (QCD), the theory of the strong nuclear force. A computational physicist can put the SU(3) gauge theory on a lattice, run a supercomputer, and out pops the proton mass. But the math provides a *value* — it doesn’t provide the *concept*. The categorical novelty of the hadron as a stable, discrete unit of reality cannot be derived purely from the field equations without importing interpretive “bridge principles” — keys we possess only because we already know the destination. QCD, in other words, can calculate what hadrons do. It cannot explain why there are hadrons rather than just fields.
The physicist’s sophisticated response is to move deeper: the underlying quantum field theory was always present. QCD is really a description of the quantum fields, not of hadrons as such, and hadron formation is derivable from QFT plus the cooling conditions. But this faces its own version of the same problem. QFT as applied to the early universe is itself a framework developed to describe structures that emerged from prior conditions. At each level, the physicist relies on laws and descriptions calibrated to the level being described — not purely to the level below.
This isn’t a minor technicality. To claim that hadron formation was “in principle derivable” from prior conditions requires that the laws governing hadrons were somehow present and operative *before hadrons existed*. That treats the laws of physics as what philosophers call nomological realism — the view that laws are real entities that *govern* matter rather than merely *describing* what matter does. It is, in effect, a Platonic commitment: these laws exist independently of the structures they describe, waiting to be instantiated as the universe cooled through the right conditions.
That is a substantial metaphysical commitment. And it’s one that goes well beyond anything physics itself establishes.
Cosmologists Know This
What’s striking is that some of the most distinguished cosmologists of the past generation have been saying exactly this — that much of modern cosmological theorizing has crossed the line from science into metaphysics, often without acknowledging the crossing.
George Ellis, who co-authored *The Large Scale Structure of Space-Time* with Stephen Hawking, has been particularly direct. He has described multiverse proposals as “cosmological myth — but this time in a scientific rather than religious mode,” and has warned that the community risks abandoning the evidence-based standards that made modern science possible. His concern isn’t with speculation itself — it’s that when the metaphysical worldview starts masquerading as established methodology, the discipline’s own standards of evidence begin to erode. When asked whether Sean Carroll’s argument that falsifiability is overrated should be taken seriously, Ellis responded that this represents “a major step backwards to before the evidence-based scientific revolution initiated by Galileo and Newton.”
Ellis is not alone. Lee Smolin has argued that the physics community is “drunk on speculation,” with some cosmologists advancing “metaphysical fantasies” about the universe being mathematics — proposals that are simply not testable. Paul Davies, in a widely discussed 2007 *New York Times* piece, argued that the faith scientists place in the immutability of physical laws has origins in Christian theology, and that the claim that science is “free of faith” is “manifestly bogus.” The string theory landscape, the multiverse, eternal inflation — these frameworks generate mathematically elegant structures, but none of them are observationally testable. As Ellis puts it: just because you have a good theory does not prove it is true. History shows that believing otherwise is “the path to delusion.”
These are not fringe critics. They are physicists of the highest distinction, and they are pointing out something important: cosmology, at its most ambitious, is already doing metaphysics. The question is whether it’s doing it well or badly — and whether it’s willing to acknowledge what it’s doing.
The Shortest Distance in Philosophy
Here is where the argument takes a turn that will make some readers uncomfortable and others feel vindicated.
David Bentley Hart, the philosopher and theologian, has spent decades articulating what classical theism actually claims — as opposed to what its popular caricatures suggest. Hart’s God is not a very large being who set the universe in motion and then retired. That’s closer to Newton’s deism, and Hart considers it bad theology. Classical theism, as Hart develops it, holds something more radical: God is not *a* being among beings but *Being itself* — the continuous ground of all existence, the reason there are laws and structures at all rather than nothing. Natural laws aren’t autonomous mechanisms operating independently of their source. They are the way the sustaining ground of reality manifests at the physical level.
Strip away the theological vocabulary, and what you have is: reality is sustained by an intelligible ground that makes possible the emergence of structure, novelty, law, and eventually consciousness. The laws of physics aren’t self-explanatory brute facts floating in a void. They participate in something deeper.
Now compare this with what the physicist must assume to claim that cosmic phase transitions were “lawful.” The laws governing hadrons were present before hadrons existed. The organizational principles that would govern chemistry were implicit before atoms formed. The regularities that make biology possible were encoded in a reality that predated life by billions of years. These laws are, as Ellis himself has noted, “eternal, unchanging, and omnipresent, with their outcomes crucially shaped by the values of specific fundamental constants.”
Eternal. Unchanging. Omnipresent. Sustaining the structure of everything that exists.
Most philosophically sophisticated physicists would resist the label “Platonist.” They would more likely describe themselves as ontic structural realists — holding that the mathematical structure of reality is itself the ultimate ground, not a description of something deeper. But ontic structural realism is, in effect, a secular redescription of what classical theology calls aseity: self-existence, the property of being one’s own ground. The physicist has replaced the Trinity with a symmetry group but retained the requirement that it be uncaused, timeless, and the sustaining ground of all that exists.
The physicist may not use the word “God.” But the metaphysical structure is remarkably close to what Hart describes. Both posit a ground that is prior to and sustains all physical structure. Both treat the intelligibility of the universe as a feature requiring explanation, not a brute fact to be accepted. The difference is that Hart names the ground and explores its implications, while the physicist typically leaves it unnamed — and then insists the unnamed version is more “scientific” than the named one.
C.S. Lewis saw this convergence from a different angle. In The Abolition of Man and Miracles, he argued that the rationality we use to investigate nature must itself be grounded in something that isn’t reducible to nature — that reason, to be trustworthy, can’t be merely the output of a physical process it’s attempting to evaluate. John Polkinghorne, a particle physicist who became an Anglican priest, spent his career arguing that the intelligibility of the universe — the fact that mathematics developed by human minds maps onto the deep structure of reality — points toward a rational ground that unites knower and known. Charles Taylor, in A Secular Age, identified what he calls the “subtraction story” — the assumption that physicalism is simply what’s left over once we subtract superstition and dogma. Taylor showed that this gets the history backwards. The immanent frame — the assumption that the natural world is all there is — isn’t a remainder. It’s a construction: a specific metaphysical framework, built up over centuries, that requires its own foundational commitments. It became the default not through philosophical argument but through a gradual shift in what felt plausible — a shift that quietly excluded questions the premodern world treated as central.
These thinkers differ on much. But they converge on a structural recognition: the distance between serious cosmological metaphysics and classical theism is much shorter than either physicists or popular atheists usually acknowledge. The physicist who treats the laws of nature as eternal, unchanging, and omnipresent has already crossed into theological territory — but without the intellectual tradition that has spent centuries thinking carefully about what that territory contains.
What This Doesn’t Mean
Let me be clear about what I’m not arguing.
I’m not arguing that physics proves God’s existence. I’m not arguing for intelligent design, which typically inserts God into gaps in current scientific explanation — gaps that science may later fill. The classical theist’s claim operates at a different level entirely: not “God explains what science can’t” but “God explains why there is something for science to investigate at all.”
I’m also not arguing that Hart, Lewis, Polkinghorne, and Taylor are right. What I’m arguing is narrower and, I think, harder to dismiss: the metaphysical commitments required by standard cosmology — eternal laws, pre-existing organizational principles, an intelligible ground that sustains all physical structure — are structurally closer to classical theism than to the flatly materialist worldview that most scientists assume they’re defending. The confident assertion that science has rendered theology obsolete depends on not examining what science itself assumes.
And this matters for the broader argument of Worlds of Awareness, because it illustrates a pattern we encounter throughout: the physicalist framework isn’t wrong about what it describes, but it consistently underestimates the metaphysical weight of its own foundations. It claims to stand on solid empirical ground while resting on exactly the kind of pre-empirical commitments it dismisses in others.
The universe began as an undifferentiated plasma and became — through a series of transitions that no prior physics could have predicted — a cosmos containing stars, oceans, whales that grieve, and minds that wonder why. Whether you call the ground of that astonishing emergence “God” or “the laws of physics” or leave it unnamed may matter less than recognizing that the ground itself demands an account. And that account, honestly pursued, leads to questions that science alone cannot answer — questions that serious thinkers across traditions have been engaging for millennia.
This post is part of a series exploring the arguments in “Worlds of Awareness,” an evolving book-length essay on consciousness, evolution, and the limits of physicalism.
I’m looking for critical readers willing to engage with full chapters — particularly people with backgrounds in physics, philosophy, or theology who can tell me where this argument overreaches. You can comment below or reach me at rsm at 137fsc dot net.
