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

5 Comments

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.

William Lane Craig lectures on the evidence for the resurrection of Jesus

Sherlock Holmes and John Watson: let’s take a look at the facts

Here is Dr. William Lane Craig giving a long-form argument for the historical event of the resurrection of Jesus, and taking questions from the audience.

The speaker introduction goes for 6 minutes, then Dr. Craig speaks for 35 minutes, then it’s a period of questions and answers with the audience. The total length is 93 minutes, so quite a long period of Q&A. The questions in the Q&A period are quite good.

Introduction:

  • Many people who are willing to accept God’s existence are not willing to accept the God of Christianity
  • Christians need to be ready to show that Jesus rose from the dead as a historical event
  • Private faith is fine for individuals, but when dealing with the public you have to have evidence
  • When making the case, you cannot assume that your audience accepts the Bible as inerrant
  • You must use the New Testament like any other ancient historical document
  • Most historians, Christian and not, accept the basic minimal facts supporting the resurrection of Jesus

Fact #1: the burial of Jesus following his crucifixion

  • Fact #1 is supported by the early creed found in Paul’s first letter to the Corinthians (1 Cor 15)
  • Fact #1 is supported by the early Passion narrative which was a source for Mark’s gospel
  • Fact #1 passes the criterion of enemy attestation, since it praises one of the Sanhedrin
  • Fact #1 is not opposed by any competing burial narratives

Fact #2: on the Sunday following his crucifixion, Jesus’ tomb was found empty by some women

  • Fact #2 is supported by the early Passion narrative which was a source for Mark’s gospel
  • Fact #2 is implied by the early creed found in Paul’s first letter to the Corinthians (1 Cor 15)
  • Fact #2 is simple and lacks legendary embellishment, which argues for an early dating
  • Fact #2 passes the criterion of embarrassment, because it has female, not male, witnesses
  • Fact #2 passes the criterion of enemy attestation, since it is reported by the Jewish leaders

Fact #3: Jesus appeared to various people in various circumstances after his death

  • Fact #3 is supported by the early creed found in Paul’s first letter to the Corinthians (1 Cor 15)
  • Fact #3 is supported by multiple, independent reports of the events from all four gospels
  • Fact #3 explains other historical facts, like the conversion of Jesus’ skeptical brother James

Fact #4: the earliest Christians proclaimed their belief in the resurrection of Jesus

  • Fact #4 explains why the earliest Christians continued to identify Jesus as the Messiah
  • Fact #4 explains why the earliest Christians were suddenly so unconcerned about being killed

Dr. Craig then asks which hypothesis explains all four of these facts. He surveys a number of naturalistic hypotheses, such as the hallucination theory or various conspiracy theories. All of these theories deny one or more of the minimal facts that have been established and accepted by the broad spectrum of historians. In order to reject the resurrection hypothesis, a skeptic would have to deny one of the four facts or propose an explanation that explains those facts better than the resurrection hypothesis.

I listened to the Q&A period while doing housekeeping and I heard lots of good questions. Dr. Craig gives very long answers to the questions. One person asked why we should trust the claim that the Jewish leaders really did say that the disciples stole the body. Another one asked why we should take the resurrection as proof that Jesus was divine. Another asks about the earthquake in Matthewand whether it is intended to be historical or apocalyptic imagery. Dr. Craig is also asked about the Jewish scholar Geza Vermes, and how many of the minimal facts he accepts. Another questioner asked about the ascension.

If you are looking for a good book to read on this topic, the best introductory book on the resurrection is “The Case for the Resurrection of Jesus” and the best comprehensive book is “The Resurrection of Jesus“.

What can we learn about communist leaders from the record of history?

I have a key that will unlock a puzzling mystery
I have a key that will unlock a puzzling mystery

The Democrats are running a lot of communist candidates in the 2020 election, so I thought it might be a good idea to take a look at what communist leaders have done in history. First, let’s see how the atheistic worldview of communist leaders affected religious people.

Here is what Josef Stalin did during his rule of Russia in the 1920s and 1930s.

The Library of Congress offers this in their “Soviet Archives exhibit”:

The Soviet Union was the first state to have as an ideological objective the elimination of religion. Toward that end, the Communist regime confiscated church property, ridiculed religion, harassed believers, and propagated atheism in the schools. Actions toward particular religions, however, were determined by State interests, and most organized religions were never outlawed.

The main target of the anti-religious campaign in the 1920s and 1930s was the Russian Orthodox Church, which had the largest number of faithful. Nearly all of its clergy, and many of its believers, were shot or sent to labor camps. Theological schools were closed, and church publications were prohibited. By 1939 only about 500 of over 50,000 churches remained open.

What’s the attitude of Democrat candidates to Bible-believing Christians? My read is that they think that Christian values need to be suppressed by the government lest they offend Democrat voters, who seem to be very easily offended these days. You can already see their animus towards Christians in their Equality Act, which eradicates conscience rights in order to protect (some) LGBT people from feeling offended.

The Ukraine Famine

Take a look at this UK Daily Mail article about Josef Stalin.

Excerpt:

Now, 75 years after one of the great forgotten crimes of modern times, Stalin’s man-made famine of 1932/3, the former Soviet republic of Ukraine is asking the world to classify it as a genocide.

The Ukrainians call it the Holodomor – the Hunger.

Millions starved as Soviet troops and secret policemen raided their villages, stole the harvest and all the food in villagers’ homes.

They dropped dead in the streets, lay dying and rotting in their houses, and some women became so desperate for food that they ate their own children.

If they managed to fend off starvation, they were deported and shot in their hundreds of thousands.

So terrible was the famine that Igor Yukhnovsky, director of the Institute of National Memory, the Ukrainian institution researching the Holodomor, believes as many as nine million may have died.

[…]Between four and five million died in Ukraine, a million died in Kazakhstan and another million in the north Caucasus and the Volga.

By 1933, 5.7 million households – somewhere between ten million and 15 million people – had vanished. They had been deported, shot or died of starvation.

The Holodomor is just one of the atrocities committed by Soviet Union communists. You may also have heard that they operated a system of labor camps for dissidents that killed millions more. The total number of people killed by Stalin is estimated at 20 to 40 million.

Stalin actually wasn’t very good at mass murder compared to another communist, Mao Zedong.

Can you name the greatest mass murderer of the 20th century? No, it wasn’t Hitler or Stalin. It was Mao Zedong.

According to the authoritative “Black Book of Communism,” an estimated 65 million Chinese died as a result of Mao’s repeated, merciless attempts to create a new “socialist” China. Anyone who got in his way was done away with — by execution, imprisonment or forced famine.

For Mao, the No. 1 enemy was the intellectual. The so-called Great Helmsman reveled in his blood-letting, boasting, “What’s so unusual about Emperor Shih Huang of the China Dynasty? He had buried alive 460 scholars only, but we have buried alive 46,000 scholars.” Mao was referring to a major “accomplishment” of the Great Cultural Revolution, which from 1966-1976 transformed China into a great House of Fear.

The most inhumane example of Mao’s contempt for human life came when he ordered the collectivization of China’s agriculture under the ironic slogan, the “Great Leap Forward.” A deadly combination of lies about grain production, disastrous farming methods (profitable tea plantations, for example, were turned into rice fields), and misdistribution of food produced the worse famine in human history.

Deaths from hunger reached more than 50 percent in some Chinese villages. The total number of dead from 1959 to 1961 was between 30 million and 40 million — the population of California.

[…]Mao kept expanding the laogai, a system of 1,000 forced labor camps throughout China. Harry Wu, who spent 19 years in labor camps, has estimated that from the 1950s through the 1980s, 50 million Chinese passed through the Chinese version of the Soviet gulag. Twenty million died as a result of the primitive living conditions and 14-hour work days.

Whenever I bring up the historical record of communism to Democrats, they always tell me that their leaders have good intentions. But the communist leaders of the past aren’t any different from the communist leaders of today. Communist leaders all start out with noble ambitions of wanting to help the poor. The problem is that they don’t know anything about economics, so whatever they try doesn’t work. Communist policies like nationalizing private industries, printing money, purging wealthy people, imposing tariffs, and imposing price controls cause enormous poverty. And then they need someone to blame for their failure to produce the results they promise.

If we were serious about helping the poor, then we would elect leaders who had experience lifting the poor out of poverty. A business leader or a governor of a state. It’s not a popularity contest. We need to choose someone who has already had success at helping the poor. And the best way to help the poor is by helping them to find work so they can earn their own success and chart their own course. After all it’s not words that affect our lives. Or the feelings we have about words we like. What affects our lives is policies that produce results. Intentions and rhetoric don’t matter, ultimately.
