Luke Barnes on the fine-tuning of the strong force and fine structure constant

By now, anyone who has had discussions about scientific evidence for the existence of God knows about the fine-tuning argument. In a nutshell, if the fundamental constants and quantities given in the Big Bang were even slightly other than they are, then the universe itself would not be hospitable for complex, embodied intelligent life.

Here is an article from The New Atlantis written by Australian cosmologist Luke Barnes.

Excerpt:

Today, our deepest understanding of the laws of nature is summarized in a set of equations. Using these equations, we can make very precise calculations of the most elementary physical phenomena, calculations that are confirmed by experimental evidence. But to make these predictions, we have to plug in some numbers that cannot themselves be calculated but are derived from measurements of some of the most basic features of the physical universe. These numbers specify such crucial quantities as the masses of fundamental particles and the strengths of their mutual interactions. After extensive experiments under all manner of conditions, physicists have found that these numbers appear not to change in different times and places, so they are called the fundamental constants of nature.

[…]A universe that has just small tweaks in the fundamental constants might not have any of the chemical bonds that give us molecules, so say farewell to DNA, and also to rocks, water, and planets. Other tweaks could make the formation of stars or even atoms impossible. And with some values for the physical constants, the universe would have flickered out of existence in a fraction of a second. That the constants are all arranged in what is, mathematically speaking, the very improbable combination that makes our grand, complex, life-bearing universe possible is what physicists mean when they talk about the “fine-tuning” of the universe for life.

Let’s look at an example – the strong force. Not only must the strong force be fine-tuned so we have both hydrogen and helium, but the ratio of the strong force must also be fine-tuned with the fine structure constant.

Barnes writes:

The strong nuclear force, for example, is the glue that holds protons and neutrons together in the nuclei of atoms. If, in a hypothetical universe, it is too weak, then nuclei are not stable and the periodic table disappears again. If it is too strong, then the intense heat of the early universe could convert all hydrogen into helium — meaning that there could be no water, and that 99.97 percent of the 24 million carbon compounds we have discovered would be impossible, too. And, as the chart to the right shows, the forces, like the masses, must be in the right balance. If the electromagnetic force, which is responsible for the attraction and repulsion of charged particles, is too strong or too weak compared to the strong nuclear force, anything from stars to chemical compounds would be impossible.

Here’s the chart he’s referencing:

Fine-tuning of the strong nuclear force and the fine structure constant
Fine-tuning of the strong nuclear force and the fine structure constant

As you can see from the chart, most of the values that the constants could take would make complex, embodied intelligent life impossible.

We need carbon (carbon-based life) because they form the basis of the components of life chemistry, e.g. proteins, sugars, etc. We need hydrogen for water. We need chemical reactions for obvious reasons. We need the light from the stars to support plant and animal life on the surface of a planet. And so on. In almost every case where you change the values of these constants and quantities and ratios from what they are, you will end up with a universe that does not support life. Not just life as we know it, but life of any conceivable kind under these laws of physics. And we don’t have any alternative laws of physics in this universe.

By the way, just to show you how mainstream these examples of fine-tuning are, I thought I would link to a source that you’re all going to be familiar with: The New Scientist.

The fine-tuning of the force of gravity

So here is an article from the New Scientist about a different constant that also has to be fine-tuned for life: the force of gravity.

Excerpt:

The feebleness of gravity is something we should be grateful for. If it were a tiny bit stronger, none of us would be here to scoff at its puny nature.

The moment of the universe‘s birth created both matter and an expanding space-time in which this matter could exist. While gravity pulled the matter together, the expansion of space drew particles of matter apart – and the further apart they drifted, the weaker their mutual attraction became.

It turns out that the struggle between these two was balanced on a knife-edge. If the expansion of space had overwhelmed the pull of gravity in the newborn universe, stars, galaxies and humans would never have been able to form. If, on the other hand, gravity had been much stronger, stars and galaxies might have formed, but they would have quickly collapsed in on themselves and each other. What’s more, the gravitational distortion of space-time would have folded up the universe in a big crunch. Our cosmic history could have been over by now.

Only the middle ground, where the expansion and the gravitational strength balance to within 1 part in 1015 at 1 second after the big bang, allows life to form.

Notice how the article also mentioned “the universe’s birth”, which is part of mainstream science.

When I’m writing to you about things like the origin of the universe, or the cosmic fine-tuning, I’m not talking to you about things that pastors found in the Bible. These discoveries are known and accepted by mainstream scientists. It’s amazing that people are constructing their worldviews without having to account for the birth of the universe and this cosmic fine-tuning. We all, as rational individuals, have to bound our view of the universe with the findings of science. Right now, those findings support the existence of a Creator and a Designer. So why am I seeing so many atheists who are just plain ignorant about these facts? Maybe we should tell them about this evidence. Maybe we should ask them why they don’t account for scientific evidence when forming their beliefs.

Positive arguments for Christian theism

Are feminists right to think that gender-neutral marriage makes women happier?

Male And Female Happiness After Feminism And Socialism
Male and female happiness throughout America’s adoption of radical feminism

I was reading this article by a feminist fiction writer on Vox, where she explains that although feminists have gotten what they wanted (careers, contraceptives, promiscuity, abortion, no-fault-divorce, daycare, etc. it hasn’t made them happier. So, what does this feminist fiction writer think would make feminists happier?

She gives two reasons why women women are still unhappy after feminism has been adopted by our society:

  • men don’t do enough housework
  • women are not as successful as men because they are discriminated against, the so-called “glass ceiling”

I think those complaints are pretty popular among feminists. Let’s take a look at some studies to see if her opinions are supported by peer-reviewed studies.

First study:

COUPLES who share housework duties run a higher risk of divorce than couples where the woman does most of the chores, a study has found.

The divorce rate among couples who shared housework equally was around 50 per cent higher than among those where the woman did most of the work.

“The more a man does in the home, the higher the divorce rate,” Thomas Hansen, co-author of the study entitled Equality in the Home, said.

Second study:

Researchers at the University of Illinois examined data on nearly 1,500 men and 1,800 women, aged between 52 and 60. Their well-being was evaluated through surveys.

The researchers first found that men’s well-being decreased once they had exited the workforce to become home-makers.

Meanwhile, the inverse was not so for women: Women’s psychological well-being was not affected by leaving their jobs to become stay-at-home mothers.

Third study:

A study called “Egalitarianism, Housework and Sexual Frequency in Marriage,” which appeared in The American Sociological Review last year, surprised many, precisely because it went against the logical assumption that as marriages improve by becoming more equal, the sex in these marriages will improve, too. Instead, it found that when men did certain kinds of chores around the house, couples had less sex. Specifically, if men did all of what the researchers characterized as feminine chores like folding laundry, cooking or vacuuming — the kinds of things many women say they want their husbands to do — then couples had sex 1.5 fewer times per month than those with husbands who did what were considered masculine chores, like taking out the trash or fixing the car. It wasn’t just the frequency that was affected, either — at least for the wives. The more traditional the division of labor, meaning the greater the husband’s share of masculine chores compared with feminine ones, the greater his wife’s reported sexual satisfaction.

Regarding the pay gap, that is entirely caused by women’s own choices. E.g. – the choice to study creative writing instead of petroleum engineering, the choice to work 35 hour weeks instead of 70 hour weeks, etc.

Fourth study:  (summarized by AEI economist)

When the [Bureau of Labor Statistics] reports that women working full-time in 2018 earned 81.4% of what men earned working full-time, that is very much different from saying that women earned 81.4% of what men earned for doing exactly the same work while working the exact same number of hours in the same occupation, with exactly the same educational background and exactly the same years of continuous, uninterrupted work experience, and with exactly the same marital and family (e.g., number of children) status. As shown above, once we start controlling individually for the many relevant factors that affect earnings, e.g., hours worked, age, marital status, and having children, most of the raw earnings differential disappears.

Fifth study:

This study leads to the unambiguous conclusion that the differences in the compensation of men and women are the result of a multitude of factors and that the raw wage gap should not be used as the basis to justify corrective action. Indeed, there may be nothing to correct. The differences in raw wages may be almost entirely the result of the individual choices being made by both male and female workers.

I think that women are entitled to make their own decisions, but they aren’t allowed to force the rest of us to subsidize their failures and celebrate their destructive outcomes.

I could go on, but I think enough has been said to show that research is very much at odds with feminist rhetoric. They feel they know what will make them happy and we gave them everything they asked for. They eliminated shaming of promiscuity with sex education. They get preferential treatment in the schools in a female-dominated education system.They are hired because of affirmative action quotas. They get expensive daycare, government schools, welfare and other programs. Taxes are raised to equalize outcomes for divorced women who choose men for feelings, and then nuke their own marriage enterprise. We have been on a long experiment of giving feminists everything they felt they wanted, at the expense of men’s rights and children’s rights, and it hasn’t even produced the results that feminists felt it would.

The social costs of feelings-based decision-making

Let’s look at two examples of policies that feminists asked for in the past, which didn’t work out the way they wanted.

I can understand why feminists would introduce sex education. They felt that “if everyone is having sex, then I won’t be the only one chasing attention from hot no-commitment bad boys by giving them recreational sex before marriage”.  They wanted to eliminate the standards of chastity and marriage-focused dating and normalize fun-focused drunken promiscuity. And they got that. But since they didn’t consult any research and evidence about how that would affect their future marriage stability and marriage happiness, they are even more unhappy than before.

How about no-fault divorce? No-fault divorce was brought in by a coalition of feminists, Marxists and trial lawyers. The Marxists want to destroy the family in order to increase dependence on the state. The trial lawyers wanted to make money. And the feminists thought that the standard approach to courting and marriage was just too much work. They didn’t want to be chaste. They didn’t want to be sober. They didn’t want to evaluate a man for traditional husband and father roles. The no-fault divorce laws gave them an escape from the messes caused by their own feelings-driven choices. But divorce just makes makes men and women much poorer, and passes the costs of supporting single mothers onto taxpayers.

And the costs of the failures of feminism are passed onto taxpayers.

Consider this study:

This paper examines the growth of government during this century as a result of giving women the right to vote. Using cross-sectional time-series data for 1870–1940, we examine state government expenditures and revenue as well as voting by U.S. House and Senate state delegations and the passage of a wide range of different state laws. Suffrage coincided with immediate increases in state government expenditures and revenue and more liberal voting patterns for federal representatives, and these effects continued growing over time as more women took advantage of the franchise. Contrary to many recent suggestions, the gender gap is not something that has arisen since the 1970s, and it helps explain why American government started growing when it did.

We are already $28 trillion in debt, partly because of feminism’s replacement of husbands and families with higher taxes and big government. Every time we transfer money from tax-paying men to feminists to fix their mistakes, it leaves less money in the hands of the men who actually want to get married. The declining value of marriage after feminism for men explains why marriage is being delayed, and why marriage rates are plunging.

Physicist Victor Stenger debates William Lane Craig: Does God Exist?

This debate took place on March 1, 2010 at Oregon State University.

In this debate, Victor Stenger does affirm his belief that the universe could be eternal in his second rebuttal (1:02:30), thus denying the standard Big Bang cosmology. He also denies the law of conservation of energy and asserts that something can come from nothing in his concluding speech (1:33:50). He also caused the audience to start laughing when he said that Jesus was not moral and supported slavery. There is almost no snark in this summary. Instead, I quoted Dr. Stenger verbatim in many places. I still think that it is very entertaining even without the snarky paraphrasing.

The debate includes 30 minutes of Q&A with the students.

Here’s the video of the debate:

Dr. Craig’s opening speech:

  • The ontological argument
  • The contingency argument
  • The cosmological argument
  • The moral argument
  • The resurrection of Jesus (3-fact version)
  • Religious experience

Dr. Stenger’s opening speech:

  • There is no scientific evidence for God’s existence in the textbooks
  • There is no scientific evidence for God acting in the universe
  • God doesn’t talk to people and tell them things they couldn’t possibly know
  • The Bible says that the Earth is flat, etc.
  • There is no scientific evidence that God answers prayers
  • God doesn’t exist because people who believe in him are ignorant
  • Human life is not optimally designed and appears to be the result of a blind, ad hoc evolutionary process
  • The beginning of the universe is not ordered (low entropy) but random and chaotic
  • It’s theoretically possible that quantum tunneling explains the origin of the universe
  • The laws of physics are not objectively real, they are “our inventions”
  • Regarding the beginning of the universe, the explanation is that something came from nothing*
  • Nothing* isn’t really nothing, it is “the total chaos that we project existed just before the big bang”
  • If something has no structure, then “it is as much nothing as nothing can be”
  • Consciousness is explainable solely on the basis of material processes
  • There are well-informed, rational non-believers in the world and God would not allow that

Dr. Craig’s first rebuttal:

Stenger’s argument that there is no objective evidence for God’s existence:

  • First, it is not required that God rely only on objective evidence in order to draw people to himself (Alvin Plantinga)
  • Second, God is not required to provide evidence to everyone, only to the people who he knows would respond to him
  • Third, Craig gave lots of objective evidence, from science, history and philosophy
  • Stenger asks for certain evidence (answered prayers, prophecy, etc.), but Craig presented the evidence we have

Stenger’s argument that the balance of energy is zero so “nothing” exists:

  • if you have the same amount of assets and liabilities, it doesn’t mean that nothing exists – your assets and liabilities exist
  • Christopher Isham says that there needs to be a cause to create the positive and negative energy even if they balance
  • the quantum gravity model contradicts observations
  • the vacuum is not the same as nothing, it contains energy and matter
  • the BVG theorem proves that any universe that is expanding must have a beginning

Stenger’s argument that mental operations can be reduced to physical operations:

  • mental properties are not reducible to physical properties
  • epiphenomenalism: is incompatible with self-identity over time
  • epiphenomenalism: is incompatible with thoughts about other things
  • epiphenomenalism: is incompatible with free will
  • substance dualism (mind/body dualism) is a better explanation for our mental experience
  • God is a soul without a body
Dr. Stenger’s first rebuttal:

Craig’s cosmological argument:

  • Craig’s premise is “everything has a cause”, but quantum mechanics has causeless events
  • There are speculative theories about how something could have come into being uncaused out of nothing
  • “I don’t know of a single working cosmologist today who believes there was a singularity prior to the Big Bang”
  • “If there wasn’t a singularity then there’s no basis for arguing that time began at that point”
  • “There’s no reason from cosmology that we know of that the universe can’t be eternal”
  • “When I talk about an eternal universe, I mean a universe that has no beginning or end”
  • The Hartle-Hawking model doesn’t have a beginning
  • “There was no violation of energy conservation by having a universe coming from nothing”
  • “The universe could have come from a previous universe for example or even just from a region of chaos”
  • The paper by Vilenkin is counteracted by other papers (he doesn’t specify which ones)

Craig’s moral argument:

  • Dr. Craig is arguing from ignorance
  • But morality can be decided by humanity just like governments pass laws, and that’s objective
  • Dr. Craig has too little respect for the human intellect
  • I don’t need to tell me that slavery is wrong
  • The Bible supports slavery
  • Atheists can behave as good as theists
  • Morality just evolved naturally as an aid to survival

Craig’s resurrection argument:

  • No Roman historians wrote about the execution of Jesus
  • The empty tomb is doubtful because it is only mentioned in the gospels, not by Paul
  • John Dominic Crossan says there was no empty tomb
  • Christianity only survived because the Roman empire thought that they were useful

Dr. Craig’s second rebuttal:

Craig’s cosmological argument:

  • There is no reason to prefer an indeterministic interpretation of quantum mechanics
  • Dr. Stenger himself wrote that deterministic interpretations of quantum mechanics are possible
  • The vacuum in quantum mechanics is not nothing
  • The quantum vacuum he proposes cannot be eternal
  • The cosmological argument does not require a singularity
  • The Hartle-Hawking model is from 1983
  • Hawking says that there is a beginning of space and time after that model
  • The Hartle-Hawking model does still have a beginning of time – the model is not eternal
  • The BVG theorem that requires a beginning for expanding universes is widely accepted among cosmologists

Craig’s moral argument:

  • Stenger redefined objective to mean that most people agree with it – but that’s not what objective means
  • Objective means right and wrong whether anyone accepts it or not
  • Richard Dawkins himself says that on atheism there is “no evil and no good” – why is he wrong?
  • Even Dr. Stenger says that morality is the same as passing laws – it’s arbitrary and varies by time and place
  • But on his view, right and wrong are the same as deciding which side of the road to drive on
  • But somethings really are right and some things are really wrong

Craig’s resurrection argument:

  • Josephus is a Roman historian and he wrote about Jesus, for example
  • There were four biographies of Jesus are the best sources for his life
  • The scholars that Stenger mentioned are on the radical fringe

Dr. Stenger’s second rebuttal:

Knowledge and the burden of proof:

  • Dr. Craig has to bear the burden of proof, not me – because his claim is more “extravagant”
  • “I don’t have to prove that a God was not necessary to create the universe”
  • “I don’t have to prove that a God did not design the universe and life”
  • “I don’t have to prove that the universe did not have a beginning”
  • “I don’t have to prove that God did not provide us with our moral sense”
  • There are a lot of books written about how morality evolved naturally
  • “I don’t have to prove that the events surrounding the supposed resurrection of Jesus did not take place”
  • Bart Ehrman says that the gospels are generally unreliable (Note: Ehrman accepts all 3 of Craig’s minimal facts)
  • Just because people are willing to die for a cause, does not make their leader God, e.g. – the Emperor of Japan

Aesthetic concerns about the universe:

  • I don’t like dark matter and I wouldn’t have made the universe with dark matter
  • I don’t like the doctrine of penal substitution
  • I don’t like the doctrine of original sin
  • I don’t like the heat death of the universe

Dr. Craig’s conclusion:

The case for atheism:

  • Dr. Stenger had two arguments and he has to support his premises
  • Dr. Craig addressed his two arguments and each premise and Dr. Stenger never came back on it

The contingency argument:

  • Dr. Stenger has dropped the refutation of this argument

The cosmological argument:

  • The theoretical vacuum he proposes cannot be eternal

The moral argument:

  • He asserts that things are wrong, but there is no grounding for that to be objective on atheism

The resurrection of Jesus:

  • There are surveys of scholars on the empty tomb and 75% of them agree with it
  • Bart Ehrman agrees with all 3 of the minimal facts that Dr. Craig presented
  • Ehrman’s objection to the resurrection is not historical: he’s an atheist – he thinks miracles are impossible

Religious experience:

  • No response from Dr. Stenger

Dr. Stenger’s conclusion

The cosmological argument:

  • “I argued that we have very good physical reasons to understand how something can come from nothing”
  • “There is a natural tendency in the universe… to go from.. simpler thing to the more complicated thing”
  • The transition from a vapor to a liquid to ice shows how something could come from nothing
  • “It cannot be proven that the universe had a beginning”

The moral argument:

  • Objective morality, which is independent of what people think, could be developed based on what people think
  • “Jesus himself was not a tremendously moral person… he had no particular regard for the poor… he certainly supported slavery… he was for the subjugation of women” (audience laughter)

The resurrection argument:

  • Bart Ehrman says that the majority of the gospels are unreliable

Religious experience:

  • I don’t see any evidence that there is anything more to religious experience than just stuff in their heads

God’s purpose of the world should be to make people feel happy:

  • God could have made people feel happier
  • God could have made people not die
  • God could could have made the universe smaller: it’s too big
  • God could have made it possible for humans to live anywhere “even in space”
