The formation of the elements required for complex embodied life is fine-tuned

Apologetics and the progress of science
Apologetics and the progress of science

Some atheists who don’t understand the fine-tuning argument like to assert that the constants and quantities that are fine-tuned to allow for the existence of complex, embodied life can be changed arbitrarily, and life would still exist as it does now. They say that maybe we would have a ridges in our foreheads like Klingons, or maybe we would have longer ears like Vulcans or maybe green skin like Orions. The evidential support for this view seems to be grounded in Star Trek TV shows, not peer-reviewed evidence. Are atheists right to ground their rejection of a cosmic Designer in science fiction television shows? What does the peer-reviewed research say?

The fine-tuning argument

First, let’s review the structure of the fine-tuning argument.

The argument goes like this:

  1. The fine-tuning of the universe to support life is either due to law, chance or design
  2. It is not due to law or chance
  3. Therefore, the fine-tuning is due to design

Although each permutation of values for the constants and quantities is equally improbable, the vast majority of the permutations will not permit life.

Let’s review:

  • Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, a universal solvent, etc.
  • In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
  • Slight changes to any of the physical constants, or to the ratios between the constants, will result in a universe inhospitable to life.
  • The range of possible values spans 70 orders of magnitude.
  • The constants are selected by whoever creates the universe. They are not determined by physical laws. And the extreme probabilities involved required put the fine-tuning beyond the reach of chance.
  • Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).

Now let’s see a specific example: carbon and oxygen formation.

Carbon is that element that can serve as a hub for larger molecules, and oxygen is also a vital element, since it is a component of water, which is required for life (universal solvent). Both are required for complex life of any imaginable kind.

Now for the study.

Here is an article on Science Daily about the fine-tuning argument.

It says:

Life as we know it is based upon the elements of carbon and oxygen. Now a team of physicists, including one from North Carolina State University, is looking at the conditions necessary to the formation of those two elements in the universe. They’ve found that when it comes to supporting life, the universe leaves very little margin for error.

Both carbon and oxygen are produced when helium burns inside of giant red stars. Carbon-12, an essential element we’re all made of, can only form when three alpha particles, or helium-4 nuclei, combine in a very specific way. The key to formation is an excited state of carbon-12 known as the Hoyle state, and it has a very specific energy — measured at 379 keV (or 379,000 electron volts) above the energy of three alpha particles. Oxygen is produced by the combination of another alpha particle and carbon.

NC State physicist Dean Lee and German colleagues Evgeny Epelbaum, Hermann Krebs, Timo Laehde and Ulf-G. Meissner had previously confirmed the existence and structure of the Hoyle state with a numerical lattice that allowed the researchers to simulate how protons and neutrons interact. These protons and neutrons are made up of elementary particles called quarks. The light quark mass is one of the fundamental parameters of nature, and this mass affects particles’ energies.

In new lattice calculations done at the Juelich Supercomputer Centre the physicists found that just a slight variation in the light quark mass will change the energy of the Hoyle state, and this in turn would affect the production of carbon and oxygen in such a way that life as we know it wouldn’t exist.

[…]The researchers’ findings appear in Physical Review Letters.

There are many, many other examples of fine-tuning of the constants and quantities to permit complex, embodied life. And, as we’ll see below, this evidence is admitted by atheists.

Atheists agree: the fine-tuning is a fact

Let me give you a citation from the best one of all, Martin Rees. Martin Rees is an atheist and a qualified astronomer. He wrote a book called “Just Six Numbers: The Deep Forces That Shape The Universe”, (Basic Books: 2001). In it, he discusses 6 numbers that need to be fine-tuned in order to have a life-permitting universe.

In chapter 1, Rees writes:

Mathematical laws underpin the fabric of our universe — not just atoms, but galaxies, stars and people. The properties of atoms — their sizes and masses, how many different kinds there are, and the forces linking them together — determine the chemistry of our everyday world. The very existence of atoms depends on forces and particles deep inside them. The objects that astronomers study — planets, stars and galaxies — are controlled by the force of gravity. And everything takes place in the arena of an expanding universe, whose properties were imprinted into it at the time of the initial Big Bang.

[…]This book describes six numbers that now seem especially significant.

[…]Perhaps there are some connections between these numbers. At the moment, however, we cannot predict any one of them from the values of the others.

[…]These six numbers constitute a ‘recipe’ for a universe. Moreover, the outcome is sensitive to their values: if any one of them were to be ‘untuned’, there would be no stars and no life. Is this tuning just a brute fact, a coincidence? Or is it the providence of a benign Creator?

There are some atheists who deny the fine-tuning, but these atheists are in firm opposition to the progress of science. The more science has progressed, the more constants, ratios and quantities we have discovered that need to be fine-tuned. Science is going in a theistic direction. Next, let’s see how atheists try to account for the fine-tuning.

Atheistic responses to the fine-tuning evidence

There are two common responses among atheists to this argument.

The first is to speculate that there are actually an infinite number of other universes that are not fine-tuned, (i.e. – the gambler’s fallacy). All these other universes don’t support life. We just happen to be in the one universe is fine-tuned for life. The problem is that there is no way of directly observing these other universes and no independent evidence that they exist.

Here is an excerpt from an article in Discover magazine, (which is hostile to theism and Christianity).

Short of invoking a benevolent creator, many physicists see only one possible explanation: Our universe may be but one of perhaps infinitely many universes in an inconceivably vast multiverse. Most of those universes are barren, but some, like ours, have conditions suitable for life.

The idea is controversial. Critics say it doesn’t even qualify as a scientific theory because the existence of other universes cannot be proved or disproved. Advocates argue that, like it or not, the multiverse may well be the only viable non­religious explanation for what is often called the “fine-tuning problem”—the baffling observation that the laws of the universe seem custom-tailored to favor the emergence of life.

The second response by atheists is that the human observers that exist today, 14 billion years after the universe was created out of nothing, actually caused the fine-tuning by going back in time and causing the universe to be fine-tuned. This solution would mean that although humans did not exist at the time the of the big bang, they are going to be able to reach back in time at some point in the future and manually fine-tune the universe.

Here is an excerpt from and article in the New Scientist, (which is hostile to theism and Christianity).

…maybe we should approach cosmic fine-tuning not as a problem but as a clue. Perhaps it is evidence that we somehow endow the universe with certain features by the mere act of observation… observers are creating the universe and its entire history right now. If we in some sense create the universe, it is not surprising that the universe is well suited to us.

So, there are two choices for atheists. Either an infinite number of unobservable universes that are not fine-tuned, or humans go back in time at some future point and fine-tune the beginning of the universe, billions of years in the past. I think I will prefer the design explanation to those alternatives.

New study: fossil discovery adds a new phyla to the explosive Cambrian explosion

Apologetics and the progress of science
Apologetics and the progress of science

It’s Wednesday, so that means another scientific discovery has been made to falsify atheism. Put it on the pile with the others, I guess.

The story from Science Daily reads like Darwinist propaganda, but you can get the main idea if you ignore the fawning naturalistic bias.

Excerpt:

A team of Virginia Tech researchers have discovered fossils of kinorhynch worms — commonly known as mud dragons — dating back more than 530 million years.

The historic find — made in South China — fills a huge gap in the known fossil record of kinorhynchs, small invertebrate animals that are related to arthropods, featuring exoskeletons and segmented bodies, but not jointed legs.

The first specimen was unearthed in rocks in Nanjiang, China, in 2013 and more fossils were found later that year and in 2014.

Helping lead the international team of scientists and biomedical engineers who unearthed, studied, and imaged the ancient, armored, worm-like creature is Shuhai Xiao, a professor of geobiology in the Department of Geosciences, part of the College of Science at Virginia Tech.

Dubbed Eokinorhynchus rarus — or rare ancient mud dragon, the newly discovered animal dates back from the Cambrian period and contains five pairs of large bilaterally placed spines on its trunk. It is believed to be related to modern kinorhynchs.

The group’s findings were published in Scientific Reports, a Nature family journal.

“Kinos represent an animal group that is related to arthropods — insects, shrimps, spiders, etc. — which are the most diverse group of animals on the planet,” said Xiao, who refers to kinorhynchs as “kinos” for short. “Although arthropod fossils date back to more than 530 million years ago, no kino fossils have ever been reported. This is a huge gap in the fossil record, with more than 540 million years of evolutionary history undocumented. Our discovery is the first report of kino fossils.”

I took a quick peek at Wikipedia to make sure, and yes, they really are their own phylum. So, brand new phylum.

Evolution News comments on the discovery:

In Figure 2.5 of Darwin’s Doubt, Steve Meyer reports that about 20 of 27 animal phyla with known fossil records appear in the Cambrian period. Prior to this find, phylum Kinorhyncha was not known to have a fossil record. Now we can update Meyer’s tabulation to report that 21 of the 28 phyla with known fossil records apparently first appear — abruptly no less — in the Cambrian explosion of animal body plans.

Despite this non-Darwinian pattern of origin, the papers’ authors speculate that these ancient (and extant) kinorhynchs might shed light on the origin of arthropods, but that’s largely only because they are segmented — as various other living phyla are as well. Given that kinorhynchs entirely lack limbs and also lack arthropod-like eyes, it seems that they aren’t going to help us much towards understanding the unique defining characteristics of arthropods.

The paper also explains that these fossils come from about 535 million years ago in a section of strata bearing the “small shelly fossils,” in the early Cambrian period. As Meyer and I have discussed, some mistakenly cite the “small shelly fossils” (SSFs) as possible evidence of a gradual evolution of the Cambrian animals. But in this case, studies of the SSFs are showing the Cambrian explosion to be more explosive.

I blogged before about the Small Shelly Fossils that are hoped (by naturalists) to be ancestors of the Cambrian phyla, but as the Evolution News article stated, they’re not. Too bad Darwinists!

New study: scientists discover that inverted retina / blind spot is not a “bad design”

Apologetics and the progress of science
Apologetics and the progress of science

Here’s what atheist Richard Dawkins says about the inverted retina:

Any engineer would naturally assume that the photocells would point towards the light, with their wires leading backwards towards the brain. He would laugh at any suggestion that the photocells might point away from the light, with their wires departing on the side nearest the light. Yet this is exactly what happens in all vertebrate eyes. Each photocell is, in effect, wired in backwards, with its wires sticking out on the side nearest to the light. This means that the light, instead of being granted an unrestricted passage to the photocells, has to pass through a forest of connecting wires, presumably suffering at least some attenuation and distortion (actually probably not much but, still, it is the principle of the thing that would offend any tidy-minded engineer!)

Source: Dawkins, Richard (1986). The Blind Watchmaker. London: Penguin Books; pp. 93-94.

Now let’s look at a new study reported in Science Daily.

They write:

From a practical standpoint, the wiring of the human eye — a product of our evolutionary baggage — doesn’t make a lot of sense. In vertebrates, photoreceptors are located behind the neurons in the back of the eye — resulting in light scattering by the nervous fibers and blurring of our vision. Recently, researchers at the Technion — Israel Institute of Technology have confirmed the biological purpose for this seemingly counterintuitive setup.

“The retina is not just the simple detector and neural image processor, as believed until today,” said Erez Ribak, a professor at the Technion — Israel Institute of Technology. “Its optical structure is optimized for our vision purposes.” Ribak and his co-authors will describe their work during the 2015 American Physical Society March Meeting, on Thursday, March 5 in San Antonio, Texas.

Ribak’s interest in the optical structure of the retina stems from his previous work applying astrophysics and astronomy techniques to improve the ability of scientists and ophthalmologists to view the retina at high detail.

Previous experiments with mice had suggested that Müller glia cells, a type of metabolic cell that crosses the retina, play an essential role in guiding and focusing light scattered throughout the retina. To test this, Ribak and his colleagues ran computer simulations and in-vitro experiments in a mouse model to determine whether colors would be concentrated in these metabolic cells. They then used confocal microscopy to produce three-dimensional views of the retinal tissue, and found that the cells were indeed concentrating light into the photoreceptors.

“For the first time, we’ve explained why the retina is built backwards, with the neurons in front of the photoreceptors, rather than behind them,” Ribak said.

You can read more on some other reasons why the inverted retina is not a bad design in this article by agnostic scientist Michael Denton. But this study is a good reminder of why Christians need to keep up with science and how we need to talk about science.

The importance of having a narrative

All Christians should be familiar with the following basic pieces of evidence which fit the war between science and naturalism narrative:

  1. The origin of the universe
  2. The cosmic fine-tuning
  3. The origin of life (biological information)
  4. The sudden origin of the Cambrian phyla
  5. The habitability/observability correlation

It’s very important to present these five basic evidences to non-Christians in the historical context. And here is the story you must tell: “In the beginning, there was the naturalism, and the naturalism tried to argue from ignorance that God was not Creator and God was not Designer. And then came the science, and now people have to give up their naturalism in order to not be crazy and irrational”. That’s the narrative you use when talking to non-Christians about science.

In the beginning was the naturalism:

  1. In pre-scientific times, atheists maintained that the universe was eternal
  2. In pre-scientific times, atheists maintained that a life-permitting universe was as likely as a life-prohibiting universe
  3. In pre-scientific times, atheists maintained that the cell was a simple blob of jello that could spontaneously emerge in some warm pond
  4. In pre-scientific times, atheists maintained that the sudden origin of the Cambrian phyla would be explained by subsequent fossil discoveries
  5. In pre-scientific times, atheists maintained that there was nothing special about our galaxy, solar system, planet or moon

But then science progressed by doing experiments and making observations.

Here are some examples of discoveries that undermined the primitive atheism:

  1. Scientists discovered redshift and the cosmic microwave background radiation (evidence for a cosmic beginning) and more!
  2. Scientists discovered the fine-tuning of gravity and of the cosmological constant and more!
  3. Scientists discovered protein sequencing and exposed the myth of “junk DNA” and more!
  4. Scientists discovered an even shorter Cambrian explosion period and the absence of precursor fossils and more!
  5. Scientists discovered galactic habitable zones and circumstellar habitable zones and more!

Atheism, as a worldview, is not rooted in an honest assessment about what science tells us about reality. Atheism is rooted in a religion: naturalism. And the troubling thing we learn from looking at the history of science is that this religion of naturalism is insulated from correction from the progress of science. Nothing that science reveals about nature seems to be able to put a dent in the religion of naturalism, at least for most atheists. Their belief in naturalism is so strong that it repels all scientific evidence that falsifies it. Atheists simply don’t let science inform and correct their worldview.
