Each Sunday in Mass when we say:

"I believe in one God, the Father Almighty, Maker of Heaven and Earth, of all that is visible and invisible ...," I think about Dark Matter and Dark Energy.

I agree that the way one believes in Dark Matter/Energy is a nice analogy for belief in God. Still, it is, in my view, an _analogy._ Dark Matter/Energy is an empirical fact (or not) about the universe. God is not an empirical fact about the universe.

I like the decay of quantum superposition as a nice analogy of Bread and Wine being transubstantiated into the Body and Blood of our Lord, too. :)

>God is not an empirical fact about the universe.

Of course he is: people experience Him every day. He's not the kind of thing you can test in a lab very easily (any more than you can easily test the existence of bigfoot in a lab), but that doesn't mean His existence isn't an empirical fact. "Empirical" means based on direct observation as opposed to theory, and there are lots of people who believe in God because they have had direct observations of Him.

You leave a lot of comments, and they are all smug, confused, and unhelpful.

I'm going to push back on part of this post. When physicists talk about "dark matter," they are usually talking about a list of observations, not a particular theory. There are various theories that try to explain the observations, particle dark matter being the most widely held view, but it's still speculative. I'm not sure if the analogy with God matches up this case.

I recommend this video on the subject: https://www.youtube.com/watch?v=PbmJkMhmrVI

Haha I separately linked that video. Angela is great.

For what it's worth, dark matter is less like a theory, and more like a set of observations you have to deal with when constructing theories. It's there, but we have no explanatory model for what that matter is or why it doesn't interact with light. Theories pick up from there and attempt to do just that by making falsifiable predictions.

To be honest, I think that undermines much of the whole analogy. Or if we do extend it the same way, I think you're angling for a definition of God that is entirely encompassed by a set of neutral observations. No way to draw any interferences about the nature of God, or extrapolate anything beyond them.

Don't agree with the disanalogy--whether God's a theory or not, if his existence explains lots of stuff, he's reasonable to believe in.

That's the problem with the analogy though. Dark matter doesn't explain anything in physics. You can't on its own extrapolate or make predictions with it outside of gross calculations about mass for regions you measure independently.

In the same way that it's difficult to jump from "dark matter must be there to explain galactic rotational observations" to "any other experiments that would rely on dark matter being there beyond its mass". I think it's hard to use the analogy to jump from "fine tuning is God's work" to "God has any other property"

Going back to your language, you want God to explain stuff in the analogy. But dark matter doesn't explain anything. It's just a problem with our measurements that's consistent with some form on non-em-interacting matter. To explain you'd need a theory about dark matter that let you make other predictions about it. An explanatory model like "God is a perfect being". Dark matter is missing that. Like, we don't know if it's a diffuse cloud, tons of mini black holes, anything concrete. It's more like the double split experiment than the standard model.

>Dark matter doesn't explain anything in physics.

Of course it does: it explains the gravitational lensing of light that we observe, it explains the rotation rate of galaxies, etc. It explains a lot of things, which is why anyone believes in it at all.

>You can't on its own extrapolate or make predictions with it

Yes you can: you can predict that the lensing of light from distant galaxies will not match the lensing you would expect based on the observable matter within those galaxies. Much in the same way that the theory that I'm short sighted allows me to predict that I will not be able to read a sign 20 feet away without my glasses. See also, the spin of galaxies will not match the observable matter, etc.

Dark matter is not just a set of observations, it is an explanation for a set of observations. It may be a broad one, with many competing theories as to the *nature* of dark matter, but that doesn't hurt the analogy - there are also many competing ideas about the nature of God.

Expand full comment

“Dark matter” IS actually just a set of observations. The *explanation* for that set of observations are things like MACHO’s, MOND, WIMPS, neutrinos, etc. good video of why by an astrophysicist: https://youtu.be/PbmJkMhmrVI?si=G4FIf9Wk7-TMnmeN timestamp 29:40 for the exact quote “dark matter is a list of observables”.

Expand full comment

Bentham is using "dark matter" to refer to a hypothetical massive, hard to detect thing that explains the "set of observations". Ie MACHOs, WIMPs, neutrinos, etc, but not MOND. This is the standard definition, it's the only definition I've ever seen. Even if it wasn't standard, so what?

You could say that dark matter is more a class of theories than a theory itself. You might be right, but again so what?

Expand full comment

There's no fact of the matter where observation becomes theory, and no such thing as non-theory-laden observation.

Expand full comment

If you call it "dark matter" it's a theory. The their is very basic: there is a bunch of matter not interacting with light. Details may vary, but the gist is huge qualities of matter we can't see. If you want to claim it's a bunch of observations without a theory, call it "missing matter puzzle" or "excess gravity puzzle". The reality is most dark matter folks actually lean towards WIMPs or the like... things that are actually dark matter theories not a blank set of observations.

It seems like we made the exact same comment :P

Haha, seems so, and at about the same time.

Hard to extend physics to philosophy without going a bit woo in the process. Physicists aren't any better at it at least. (Thinking about Wigner's quantum theory of the mind)

Dark matter is distinct from God. Your definition of God is “any set of ad how categories which will ‘explain’ anything I want it to”. Obviously, if you arbitrarily define something as a thing which explains everything, it will explain everything.

Dark matter, on the other hand, only explains a limited number of connected phenomena. A physicist who looks at every unexplained thing ever and said “dark matter!” would be a crack.

> When it comes to God, we observe lots of surprising things. Constants of the universe finely-tuned—falling in an extremely narrow range needed for the formation of complex structures; complex laws that produce valuable states of affairs; consciousness that fits poorly into our picture of reality, surprisingly harmonious. That’s all super surprising!

None of this is surprising. You have presented zero evidence that another set of laws would not produce conscious life. There’s nothing special about our particular arrangement of laws. If gravity were doubled, there may well be conscious things that exist entirely differently who make identical arguments. Reasoning from a sample size of one like this is not permissible.

Expand full comment

If the gravitational constant was doubled it is highly unlikely that you would have stable stars burning long enough for life to evolve. Or at least that is according to current models of the universe, it might be one day we discover new laws which contradict this

I’m not contending that there would be humans and stars. There may well not be.

But consciousness? I don’t see why that would be impossible.

Expand full comment

First let me correct myself. The gravitational constant actually seems to be the most elastic of the fundamental constants, you could probably increase by an order of magnitude and still have a fine tuned universe.

With consciousness: In order to have consciousness or other interesting things in the universe, you probably need chemistry, available energy and sufficient time. It seems that uf you change the physical constants you could easily end up witha universe only consisting of inert hydrogen.

Martin Rees has written some articles and books on the subject if you find it interesting.

1. BB doesn’t use God as an ad hoc explanation tool as each of the arguments works only from the assumption that God is a perfect being. He doesn’t make leaps like “a perfect being would love bagels”, only things like “a perfect being would do good things”.

2. If gravity were doubled the universe would’ve instantly collapsed in on itself, so there would be no time or matter for things to become conscious.

> He doesn’t make leaps like “a perfect being would love bagels”, only things like “a perfect being would do good things”.

He actually does make a claim that a perfect being would necessarily create bagels, since bagels exist and he believes that God explains everything.

2. Gravity being doubled would probably not cause the universe to collapse in on itself, since the initial phase of expansion of the universe occurred much faster than the speed of light and utterly overwhelmed the gravitational effect. The universe would certainly look different, but there’s no evidence that some analogue to the Big Bang would be impossible under an alternate model of physics.

Expand full comment

I don't know about "instantly collapsed on itself" but it is true that if the force of gravity was twice as strong then the universe would have collapsed back in on itself after an initial expansion, long before the conditions for life would exist.

"Perfect being" ex machina.

Shouldn’t you expect a perfect being to do good things? Are you denying this part or are you denying the moral truths?

And are the dark matter particles simps, wimps, or gimps?

Thanks for this. I'm now imagining DM as akin to another dimension. There, people are detecting the effects of matter and wondering if it's God or a mysterious other dimension. All fun stuff.

Good post. Interesting analogy.

There is something I'd be curious to hear your opinion on, if you have the time - and that is near-death experiences. YouTube is absolutely loaded with videos about the near-death experiences of various people. I could link you to one or two if you want, but it might be more fruitful if you do your own research there, as what one person finds most compelling/interesting isn't necessarily the same as what another person will find compelling/interesting.

I suggest this since it might dovetail nicely with your theistic beliefs and exploration of various theistic arguments.

To be pedantic: there isn't "a bunch of dark matter" in front of the elephant. Dark matter doesn't "track" ordinary matter at planetary scales (if it did, we'd have noticed it a lot sooner), so we'd expect Earth's dark matter density to be roughly the same as the solar system average; much lower than Earth's matter density.

Expand full comment

I think I once saw it calculated that if dark matter is evenly distributed in the galaxy, the masd of dark matter inside the earth is equivalent to the mass of a squirrel.

That said, there might be a bunch of dark matter between us and that elephant. It could all be particles that just only interact through gravity, and there is a tiny amount od them everywhere.

Or perhaps I misunderstood what you meant by track ordinary matter.

Expand full comment

With a spherical earth and dark matter density of 0.4 GeV/cc you get 770 grams, so a squirrel is about right. That was my point: that despite there being more dark matter than ordinary matter in the whole universe, there isn't very much on earth.

By "track" I meant that planet-sized objects don't have a noticeable quantity of dark matter following them around due to their gravity - that only happens at a galactic scale.

My comment could have been clearer.

Handy analogies to aspects of theism come and go. Dark matter may be squished by better math, but the conjunction of divine providence and divine hiddenness will still have the same shape it has had for the last 2500 years or so, it seems to me.
