Luke Barnes discusses the fine-tuning of the fine structure constant

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

Here is an article from The New Atlantis written by cosmologist Luke Barnes about one specific example of cosmic fine-tuning. (H/T Uncommon Descent via J. Warner Wallace tweet)


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.

These constants represent the edge of our knowledge. Richard Feynman called one of them — the fine-structure constant, which characterizes the amount of electromagnetic force between charged elementary particles like electrons — “one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man.”

[…]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.

Atheists, both rank-and-file and expert, almost universally misunderstand the fine-tuning argument. They imagine that if the constants and quantities specified at the origin of the universe were different, then humans would just have green skin, or maybe forehead ridges, or pointy ears. Atheists tend to get their view of science from science fiction in novels or television or movies. Just this week I was talking to an agnostic woman (who since reverted to atheism) and brought up the fine-tuning argument. And she said “well, maybe if the initial constants and quantities were different, then we would have evolved differently”. No, the whole point is that life of any conceivable kind becomes impossible if the constants and quantities are altered higher or lower. Even slightly. It’s not that you have green skin, pointy ears, and forehead ridges. It’s that you have a universe that recollapses into a hot fireball, or contains only hydrogen, or does not form stars and planets at all.

I got the impression that she hadn’t read anything about the fine-tuning from peer-reviewed scientific publications, but had just read popular responses to it from atheists with degrees in English and drama and philosophy. If you want to understand a scientific argument, then you have to go to the scientific publications, and read the science. Here is an excellent start, from two astrophysicists, and published by Cambridge University Press.

So what does the scientific evidence actually show?

Barnes explains:

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.

Stars are particularly finicky when it comes to fundamental constants. If the masses of the fundamental particles are not extremely small, then stars burn out very quickly. Stars in our universe also have the remarkable ability to produce both carbon and oxygen, two of the most important elements to biology. But, a change of just a few percent in the up and down quarks’ masses, or in the forces that hold atoms together, is enough to upset this ability — stars would make either carbon or oxygen, but not both.

It’s very important that theists are well-equipped to explain how individual cases of fine-tuning work. We need to know what you lose if you alter these constants and quantities even slightly. You can read about some more examples in this previous post.

The Economist: marriage is still the best place for children

Marriage and family
Marriage and family

I stopped reading The Economist when they endorsed the socialist failure Barack Obama, who doubled the national debt to $20 trillion in only 8 years. However, even a stopped clock is right twice a day. And here is one of those times.


However, there is one big reason to worry about the quality and longevity of people’s intimate bonds. It is that relationships often produce children, and children are profoundly affected by how their parents get on.

You could make enough confetti for a summer of weddings with all the academic papers that show how much children gain from being brought up in stable, loving families, and how much they suffer when those families break down. Culture and customs make little difference. In Japan, four-fifths of single-parent households emerge when couples divorce—a much higher share than in the West, where people usually slip into single parenthood without marrying. Japanese children living with only one parent nonetheless perform significantly worse in school tests, just as children from single-parent families do in Europe and America. In poorer countries, family breakdown can kill. According to one recent estimate, the chance that an African child will die before turning five is about 25-30 per 1,000 for those born into stable families, but 35-40 per 1,000 for the children of single, divorced or widowed parents.

Marriage is not always good for children. They do not benefit when a parent marries somebody who is not their mother or father, and seem to suffer if the parent they live with cycles through several relationships. What they seem to need most is for their biological parents to stick together. And one strong claim that can be made for marriage is that it appears to glue parents together more tightly than any other arrangement.

This part is key, especially for those millennials who think that cohabitating before marrying makes the marriage more secure:

Analysis of one large American data set by Kathryn Edin and Laura Tach, two sociologists, shows that 27% of marriages broke down within nine years of a child being born. By contrast, among couples who were merely cohabiting when a child appeared, 53% separated within nine years—and most of the remaining 47% were married by that point. Among couples who were dating but not living together when the child was born, 81% had split up.

Again, this pattern runs across national and cultural borders. Cohabiting couples behave a bit more like married couples in countries where giving birth outside marriage is very common, such as Estonia and Norway. But they seldom attain the same level of stickiness as married couples, even after controlling for the mother’s level of education.

Cohabitation doesn’t work, because it’s basically saying that I’m going to try the other person and see if I like the other person, and that sex is required to know if I like the other person. It doesn’t really matter that you know the other person really well, because you can always get out of cohabitation just by leaving. Marriage says that I’m going to commit to the other person for life, through thick and thin. Here, both people tend to do a more thorough job of selecting their partner, perhaps even consulting fathers for advice. Why? Because getting out of a marriage is a lot harder to do, and more expensive.

In the past, I’ve blogged about some factors that can make your marriage pretty much divorce proof: things like chastity, not spending too much on the wedding, age of the man and woman at marriage, education levels of each spouse, number of people attending the wedding ceremony, isolation from other divorced people, church attendance, and so on. The truth is that you can engineer a marriage that’s practically divorce proof. But if you insist on spontaneity and following your heart, then you aren’t going to care what studies say works best. A stable marriage takes preparation, and that means making pro-marriage choices all throughout your life before your marriage, instead of doing what feels right to you in the moment. What feels good in the moment is almost never the right choice if your goal is a stable marriage.

How the WMAP satellite confirmed nucleosynthesis predictions and falsified atheism

Christianity and the progress of science
Christianity and the progress of science

Prior to certain scientific discoveries, most people thought that the universe had always been here, and no need to ask who or what may have caused it. But today, that’s all changed. Today, the standard model of the origin of the universe is that all the matter and energy in the universe came into being in an event scientists call “The Big Bang”. At the creation event, space and time themselves began to exist, and there is no material reality that preceded them.

So a couple of quotes to show that.

An initial cosmological singularity… forms a past temporal extremity to the universe. We cannot continue physical reasoning, or even the concept of spacetime, through such an extremity… On this view the big bang represents the creation event; the creation not only of all the matter and energy in the universe, but also of spacetime itself.

Source: P. C. W. Davies, “Spacetime Singularities in Cosmology,” in The Study of Time III, ed. J. T. Fraser (Berlin: Springer Verlag ).

And another quote:

[A]lmost everyone now believes that the universe, and time itself, had a beginning at the big bang.

Source: Stephen Hawking and Roger Penrose, The Nature of Space and Time, The Isaac Newton Institute Series of Lectures (Princeton, N. J.: Princeton University Press, 1996), p. 20.

So, there are several scientific discoveries that led scientists to accept the creation event, and one of the most interesting and famous is the discovery of how elements heavier than hydrogen were formed.

Nucleosynthesis: forming heavier elements by fusion
Nucleosynthesis: forming heavier elements by fusion

Here’s the history of how that discovery happened, from the National Aeronautics and Space Administration (NASA) web site:

The term nucleosynthesis refers to the formation of heavier elements, atomic nuclei with many protons and neutrons, from the fusion of lighter elements. The Big Bang theory predicts that the early universe was a very hot place. One second after the Big Bang, the temperature of the universe was roughly 10 billion degrees and was filled with a sea of neutrons, protons, electrons, anti-electrons (positrons), photons and neutrinos. As the universe cooled, the neutrons either decayed into protons and electrons or combined with protons to make deuterium (an isotope of hydrogen). During the first three minutes of the universe, most of the deuterium combined to make helium. Trace amounts of lithium were also produced at this time. This process of light element formation in the early universe is called “Big Bang nucleosynthesis” (BBN).

The creation hypothesis predicts that there will be specific amounts of these light elements formed as the universe cools down. Do the predictions match with observations?

Yes they do:

The predicted abundance of deuterium, helium and lithium depends on the density of ordinary matter in the early universe, as shown in the figure at left. These results indicate that the yield of helium is relatively insensitive to the abundance of ordinary matter, above a certain threshold. We generically expect about 24% of the ordinary matter in the universe to be helium produced in the Big Bang. This is in very good agreement with observations and is another major triumph for the Big Bang theory.

Moreover, WMAP satellite measurements of mass density agree with our observations of these light element abundances.

Here are the observations from the WMAP satellite:

Scientific observations match predictions
Scientific observations match predictions

And here is how those WMAP measurements confirm the Big Bang creation event:

However, the Big Bang model can be tested further. Given a precise measurement of the abundance of ordinary matter, the predicted abundances of the other light elements becomes highly constrained. The WMAP satellite is able to directly measure the ordinary matter density and finds a value of 4.6% (±0.2%), indicated by the vertical red line in the graph. This leads to predicted abundances shown by the circles in the graph, which are in good agreement with observed abundances. This is an important and detailed test of nucleosynthesis and is further evidence in support of the Big Bang theory. 

“An important and detailed test”.

For completeness, we should learn how elements heavier than these light elements are formed:

Elements heavier than lithium are all synthesized in stars. During the late stages of stellar evolution, massive stars burn helium to carbon, oxygen, silicon, sulfur, and iron. Elements heavier than iron are produced in two ways: in the outer envelopes of super-giant stars and in the explosion of a supernovae. All carbon-based life on Earth is literally composed of stardust.

That’s a wonderful thing to tell a young lady when you are on a date: “your body is made of stardust”. In fact, as I have argued before, this star formation, which creates the elements necessary for intelligent life, can only be built if the fundamental constants and quantities in the universe are finely-tuned.

Now, you would think that atheists would be happy to find observations that confirm the origin of the universe out of nothing, but they are not. Actually, they are in denial.

Here’s a statement from the Secular Humanist Manifesto, which explains what atheists believe about the universe:

Religious humanists regard the universe as self-existing and not created.

For a couple of examples of how atheistic scientists respond to the evidence for a cosmic beginning, you can check out this post, where we get responses from cosmologist Lawrence Krauss, and physical chemist Peter Atkins.

You cannot have the creation of the universe be true AND a self-existing, eternal universe ALSO be true. Someone has to be wrong. Either the science is wrong, or the atheist manifesto is wrong. I know where I stand.

Positive arguments for Christian theism

1 Corinthians 15: the earliest source for the basic facts about the life of Jesus

The Son of God became flesh and dwelt among us
The Son of God became flesh and dwelt among us

First, the creed – which is found in 1 Corinthians 15:3-8:

3For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures,

4that he was buried, that he was raised on the third day according to the Scriptures,

5and that he appeared to Peter, and then to the Twelve.

6After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep.

7Then he appeared to James, then to all the apostles,

8and last of all he appeared to me also, as to one abnormally born.

Almost all historians accept this creed as dating back to within 5 years of the death of Jesus. But why?

Here’s a great article from Eric Chabot, director of Ratio Christi Apologetics Alliance, The Ohio State University to explain why.


The late Orthodox Jewish scholar Pinchas Lapide was so impressed by the creed of 1 Cor. 15, that he concluded that this “formula of faith may be considered as a statement of eyewitnesses.” (5)

Paul’s usage of the rabbinic terminology “passed on” and “received” is seen in the creed of 1 Cor. 15:3-8:

“For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures, and that he appeared to Peter, and then to the Twelve. After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep. Then he appeared to James, then to all the apostles, and last of all he appeared to me also, as to one abnormally born.”

[…]While the word “received” (a rabbinical term) can also be used in the New Testament of receiving a message or body of instruction or doctrine (1 Cor.11:23; 15:1, 3; Gal. 1:9, 12 [2x], Col 2:6; 1 Thess 2:13; 4:1; 2 Thess 3:6), it also means means “to receive from another.” This entails that Paul received this information from someone else at an even earlier date. 1 Corinthians is dated 50-55 A.D. Since Jesus was crucified in 30-33 A.D. the letter is only 20-25 years after the death of Jesus. But the actual creed here in 1 Cor. 15 was received by Paul much earlier than 55 A.D.

[…]Even the co-founder Jesus Seminar member John Dominic Crossan, writes:

“Paul wrote to the Corinthians from Ephesus in the early 50s C.E. But he says in 1 Corinthians 15:3 that “I handed on to you as of first importance which I in turn received.” The most likely source and time for his reception of that tradition would have been Jerusalem in the early 30s when, according to Galatians 1:18, he “went up to Jerusalem to visit Cephas [Peter] and stayed with him fifteen days” (11).

This comment by Crossan makes sense because within the creed Paul calls Peter by his Aramic name, Cephas. Hence, if this tradition originated in the Aramaic language, the two locations that people spoke Aramaic were Galilee and Judea. (12) The Greek term “historeo” is translated as “to visit” or “to interview.” (13) Hence, Paul’s purpose of the trip was probably designed to affirm the resurrection story with Peter who had been an actual eyewitness to the resurrected Christ (1 Cor. 15:5).

I know what you’re thinking. You’re thinking “Hey WK, isn’t John Dominic Crossan that wacky liberal atheist who is on the far-left fringe of historical Jesus scholarship? So wacky, that he actually thought that Secret Gospel of Mark was real, instead of just being a hoax?” Yes, that’s the nutty John Dominic Crossan I mean. The very one.

Here’s a bit more about this early creed from Gary Habermas.


Paul is clear that this material was not his own but that he had passed on to others what he had received earlier, as the center of his message (15:3). There are many textual indications that the material pre-dates Paul. Most directly, the apostle employs paredoka and parelabon, the equivalent Greek terms for delivering and receiving rabbinic tradition (cf. 1 Cor. 11:23). Indirect indications of a traditional text(s) include the sentence structure and verbal parallelism, diction, and the triple sequence of kai hoti Further, several non-Pauline words, the proper names of Cephas (cf. Lk. 24:34) and James, and the possibility of an Aramaic original are all significant. Fuller attests to the unanimity of scholarship here: “It is almost universally agreed today that Paul is here citing tradition.”[4] Critical scholars agree that Paul received the material well before this book was written.[5]

The most popular view is that Paul received this material during his trip to Jerusalem just three years after his conversion, to visit Peter and James, the brother of Jesus (Gal. 1:18-19), both of whose names appear in the appearance list (1 Cor. 15:5; 7). An important hint here is Paul’s use of the verb historesai (1:18), a term that indicates the investigation of a topic.[6] The immediate context both before and after reveals this subject matter: Paul was inquiring concerning the nature of the Gospel proclamation (Gal. 1:11-2:10), of which Jesus’ resurrection was the center (1 Cor. 15:3-4, 14, 17; Gal. 1:11, 16).

Critical scholars generally agree that this pre-Pauline creed(s) may be the earliest in the New Testament. Ulrich Wilckens asserts that it “indubitably goes back to the oldest phase of all in the history of primitive Christianity.”[7] Joachim Jeremias agrees that it is, “the earliest tradition of all.”[8] Perhaps a bit too optimistically, Walter Kasper even thinks that it was possibly even “in use by the end of 30 AD . . . .”[9]

Indicating the wide approval on this subject, even more skeptical scholars frequently agree. Gerd Ludemann maintains that “the elements in the tradition are to be dated to the first two years after the crucifixion of Jesus. . . . not later than three years. . . . the formation of the appearance traditions mentioned in I Cor.15.3-8 falls into the time between 30 and 33 CE. . . .”[10] Similarly, Michael Goulder thinks that it “goes back at least to what Paul was taught when he was converted, a couple of years after the crucifixion.”[11] Thomas Sheehan agrees that this tradition “probably goes back to at least 32-34 C.E., that is, to within two to four years of the crucifixion.”[12] Others clearly consent.[13]

Overall, my recent overview of critical sources mentioned above indicates that those who provide a date generally opt for Paul’s reception of this report relatively soon after Jesus’ death, by the early to mid-30s A.D.[14] This provides an additional source that appears just a half step removed from eyewitness testimony.

(3) Paul was so careful to assure the content of his Gospel message, that he made a second trip to Jerusalem (Gal. 2:1-10) specifically to be absolutely sure that he had not been mistaken (2:2). The first time he met with Peter and James (Gal. 1:18-20). On this occasion, the same two men were there, plus the apostle John (2:9). Paul was clearly doing his research by seeking out the chief apostles. As Martin Hengel notes, “Evidently the tradition of I Cor. 15.3 had been subjected to many tests” by Paul.[15]

These four apostles were the chief authorities in the early church, and each is represented in the list of those who had seen the resurrected Jesus (1 Cor. 15:5-7). So their confirmation of Paul’s Gospel preaching (Gal. 2:9), especially given the apostolic concern to insure doctrinal truth in the early church, is certainly significant. On Paul’s word, we are again just a short distance from a firsthand report.

(4) Not only do we have Paul’s account that the other major apostles confirmed his Gospel message, but he provides the reverse testimony, too. After listing Jesus’ resurrection appearances, Paul tells us he also knew what the other apostles were preaching regarding Jesus’ appearances, and it was the same as his own teaching on this subject (1 Cor. 15:11). As one, they proclaimed that Jesus was raised from the dead (15:12, 15). So Paul narrates both the more indirect confirmation of his Gospel message by the apostolic leaders, plus his firsthand, direct approval of their resurrection message.

That’s how solid this early creed is – even atheists like Crossan and Ludemann accept it as historically reliable. It’s historical bedrock, as Michael Licona likes to say. This is the stuff that everyone accepts – across the ideological spectrum. How do you account for this evidence in your worldview, especially given that Paul never recanted his preaching about Jesus?

New study: 1 in 8 divorces is caused by student loan debt

I already mentioned the studies that show that marrying a non-virgin is less stable than marrying a virgin. But what about student loans? Are they a risk factor for divorce, too? I was reading over at Captain Capitalism and saw this CNBC article, which discusses data relevant to our recent discussion about whether men ought to prefer debt-free virgins without tattoos.


When it comes to student loan debt, “for richer, for poorer” doesn’t quite cut it.

In general, finances are the leading cause of stress in a relationship, according to a study by SunTrust Bank, but student debt takes a particularly hard toll on a marriage.

More than a third of borrowers said college loans and other money factors contributed to their divorce, according to a recent report from Student Loan Hero, a website for managing education debt.

In fact, 13 percent of divorcees blame student loans specifically for ending their relationship, the report found. Student Loan Hero surveyed more than 800 divorced adults in June.

Now, when deciding whether to marry and who to marry, it does make sense to me to think about what needs to be bought and how much these things cost, and where the money will come from. It just makes sense to me that people who are REALLY interested in marriage will be interested in doing what works to prepare for marriage. You can’t just do whatever you want before marrying, because marriage involves being faithful to your spouse, and buying things that you need for the marriage enterprise, like a home, and baby stuff. It doesn’t make any sense to say “I want to get married” and then not prepare for marriage by being careful about what behavior marriage requires of you.

This 2017 article from Harvard Business Review is interesting.

It says:

Examining 46,934 resumes shared on Glassdoor by people who graduated between 2010 and 2017, the researchers looked at each person’s college major and their post-college jobs in the five years after graduation. They then estimated the median pay for each of those jobs (also using Glassdoor data) for employees with five years of experience or less. Their key finding: “Many college majors that lead to high-paying roles in tech and engineering are male dominated, while majors that lead to lower-paying roles in social sciences and liberal arts tend to be female dominated, placing men in higher-paying career pathways, on average.”

Here’s the plot, and you can click it to expand it:

Starting salaries by major, broken out by gender
Median salaries by major, broken out by gender – don’t study things at the bottom!

Maybe we can just simplify this whole issue by saying “it’s unwise to marry people who choose not to prepare themselves for marriage”. That goes for men and women, by the way. Basically, you can avoid student loans if you study something that you don’t feel like studying, and work jobs that you don’t feel like working, and don’t buy things that you feel like buying. Don’t marry people who are led by their feelings. Marry someone who demonstrates self-control.

Anyway, I feel obligated to post a relevant Dave Ramsey video, just to remind everyone that stewardship of money is a Christian virtue, and that being forgiven by Jesus for your sins doesn’t make you good with money.

This one from 2014: (H/T Robb)

When I was in high school, I was far more interested in becoming an English teacher than I was in becoming a software engineer. It was my Dad who overruled my choice of college major when I was still in high school. He had me take a first-year English course at a local university. When I saw how politicized and useless it was (they were studying all sorts of politically correct postmodern relativist stuff, instead of the Great Works, and they weren’t trying to learn any wisdom from any of it), I chose computer science. I did what was likely to work, instead of what was easy and fun and made me feel good. I think this makes me a grown-up. And marriage should only be done if there are two grown-ups involved in the enterprise.
