The Core Theory

Carroll spends several chapters discussing the quantum mechanical framework for the Core Theory, as he calls it. Quantum mechanics has been an extremely successful physical theory exquisitely predicting with enormous precision some parameters in particle physics. But what many people have heard of quantum theory is more about the various interpretations applied by physicists (e.g. Bohr’s abstract physical description, or, Everett’s many-worlds) to the way the theory might work beneath what we can measure.

Regardless of the correct interpretation it has enjoyed enormous success as a theory of physics in what is called the standard model of particle physics. The second very successful theory is general relativity—Einstein’s theory of gravity. Both work extremely well in their respective domains of operation, but outside that, in the realm of what is called quantum gravity neither operate nor has a theory been found to unite them. But that is exactly what Stephen Hawking and others have been seeking, to have the Universe begin in a quantum fluctuation of a meta-stable false vacuum.

But even though we have this limitation, in the realm of what humans can measure, Carroll has faith and writes:

“What we can do is show that physics by itself is fully up to the task of accounting for what we see.” (p.179)

However he admits that one class of particles not part of the current Core Theory are those that make up “dark matter” in the Universe. Such alleged weakly interacting putative particles are allowed for in the Core Theory because they are so weakly interacting with normal atomic matter that they are hard to detect. I would argue that dark matter and other dark entities are a philosophical construct used to keep the standard big bang cosmology from being discredited.1 Dark matter was first needed to explain the dynamics of spiral galaxies. Now it seems that it is no longer needed, when standard physics is applied correctly.2

In the Prologue the author writes:

“We have two goals ahead of us. One is to explain the story of our universe and why we think it’s true, the big picture as we currently understand it. It’s a fantastic conception. We humans are blobs of organised mud, which through the impersonal workings of nature’s patterns have developed the capacity to contemplate and cherish and engage with the intimidating complexity of the world around us. To understand ourselves, we have to understand the stuff out of which we are made, which means we have to dig deeply into the realm of particles and forces and quantum phenomena, not to mention the spectacular variety of ways that those microscopic pieces can come together to form organized systems capable of feeling and thought.

The other goal is to offer a bit of existential therapy. … By the old way of thinking, human life couldn’t possibly be meaningful if we are ‘just’ collections of atoms moving around in accordance with the laws of physics. That’s exactly what we are, but it’s not the only way of thinking about what we are. We are collections of atoms, operating independently of any immaterial spirits or influences, and we are thinking and feeling people who bring meaning into existence by the way we live our lives.” (p.3)

The latter he must say because later he says that the material world is all there is. He argues that there is no such thing as a spirit or a soul that is not part of our material body. When we die that is it, there is nothing beyond life.

Carroll is a student of many philosophers, mostly atheists, or who are at least those who challenge a conservative Christian worldview of life.  For example he mentions, Descartes, Nietzsche, Laplace, Hume, Leibniz, Spinoza, Lewis (not C.S.), Russell, Wittgenstein, Kierkegaard and others. But it would seem that the author relies more strongly on the so-called Enlightenment philosophy of the atheist Scotsman David Hume.
