Here’s the 66-minute video featuring Dr. Stephen C. Meyer, who holds the Ph.D in philosophy of science from Cambridge University, and other degrees in the hard sciences.

The lecture starts really, really slowly. You can just fast-forward to the 12 minute mark, or you might die of boredom.


  • Up until the the last 100 years or so, everyone agreed that the universe was eternal
  • This is at odds with the traditional Christian view that God created the universe
  • Materialism, the view that matter is all there is, requires eternally existing matter
  • Discovery #1: Hubble discovers that the universe is expanding (redshift observation)
  • The expanding universe was resisted by proponents of the eternal universe, like Einstein
  • Some naturalists even proposed speculative static models like the steady-state model
  • However, not of the speculative models fit with observations and experimental results
  • Discovery #2: Penzias and Wilson discover the cosmic microwave background radiation
  • Measurements of this background radiation confirmed a prediction of the Big Bang theory
  • The steady-state theory was falsified of by the discovery of this background radiation
  • The oscillating model was proposed to prevent the need for an absolute beginning
  • But the oscillating model is not eternal, it loses energy on each “bounce”
  • A paper by Alan Guth and Marc Sher from 1982 proved that our universe will not bounce
  • In addition, experiments reveal that the universe will expand forever, and not contract
  • The beginning of the universe is more at home in a theistic worldview than an atheistic one
  • The beginning of the universe fits in well with the Bible, e.g. – Genesis 1, Titus 1, etc.

In case you are wondering about what the evidence is for the Big Bang, here are 3 of the evidences that are most commonly offered:

Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe. A hot, dense, and expanding environment at the beginning could produce these nuclei in the abundance we observe today. Third, astronomers could actually observe the cosmic background radiation—the afterglow of the explosion—from every direction in the universe. This last evidence so conclusively confirmed the theory of the universe’s beginning that Stephen Hawking said, “It is the discovery of the century, if not of all time.”

By the way, Dr. Meyer also does a great job of explaining the problem of proteins, DNA and the origin of life in this lecture. And you can hear him defend his views in this debate podcast with Keith Fox and in this debate podcast with Peter Atkins. He does a great job in these debates.

Positive arguments for Christian theism

Do moral dilemmas undermine objective moral absolutes?

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

One reason why some people reject the existence of objective morality is because moral absolutes can conflict.

Canadian philosopher Michael Horner to explains the problem.

He writes:

You may have been confronted with the story of the Nazi soldier coming to the door of the family who are hiding some Jewish people in their home and asking them point blankly, “Are there any Jews here?” The person telling the story then asks you, “What would you say?” or more precisely, “What should you say?”

[…]I think for many people the term moral absolutes connotes ideas like inflexibility and rigidity, and that there can never be exemptions. I have also found that many people believe that holding to moral absolutes means that circumstances are not relevant in a moral evaluation and that moral absolutism cannot handle moral dilemmas. But in fact it is possible to believe in moral absolutes, or as I prefer to call them objective moral values, without adhering to these connotations I have mentioned.

For many people to believe in moral absolutes is to believe in rules that no other rules can ever trump. It follows from this that moral absolutes are all equal and there can never be any exemptions. But what if moral absolutes exist in a hierarchy?

We know from experience that very often more than one moral rule applies to a situation. This often leads to moral dilemmas. So in the ‘hiding the Jews example’ the moral rule of telling the truth seems to apply to the situation, but it would seem that the moral rule to protect innocent human life from torture and murder applies also.

If absolutes are all equal there is no way out of the dilemma. You can’t choose one absolute over another because in doing so you would be violating at least one absolute which, in their view, is supposed to be inviolable.

So, in this case, it seems as if the moral absolutist is stuck in a dilemma. If you lie to save the innocent life, then that would be wrong. But if you tell the truth and hand the innocent person over to murderers, then that would be wrong. Does this really disprove objective moral absolutes?

This problem annoys me, because I know this is the kind of objection to objective morality that annoying philosophy lecturers like to push onto freshmen in order to convince them that morality is nonsense.  But does the moral dilemma objection really work?

More Horner:

[…][I]f moral absolutes exist in a hierarchy and the circumstances or the situation were relevant in determining which absolute takes precedent, then there may be a solution to the moral dilemma. That is exactly what I think is the case in the example. I for one have no difficulty knowing that the morally right thing to do in that situation is to protect the life of innocent people from torture and murder rather than tell the truth to a person who has torture and murder in their plans. My moral intuitions are very clear about this.

If someone objects and says, “No, you must always tell the truth. After all it is an absolute, and absolutes by definition can never be violated,” I would point out that they are just using a different hierarchy, putting truth telling above protecting the life of innocent people from torture and murder. There is no way to avoid making a judgment like that since more than one absolute does apply to the situation. I would just ask them to think it through again, and once they see that they have to make a judgment based on some sort of hierarchy in that situation, then I think most people’s moral intuitions will affirm that protecting the lives of innocent people from torture and murder, in that situation, trumps truth telling. There is no way to avoid choosing one over the other.

But isn’t this moral relativism? After all, we are deciding what to do based on the situation! It’s relativism, isn’t it?

No, it isn’t, because there is always one right thing to do in every situation. In every situation, you always follow the weightiest moral rule. The right thing to do does not depend on your subjective state of mind. It is an objective moral duty, and it is the same for everyone, across all times and in all places. That’s what objective morality means -what is right and wrong is not determined by personal preferences or cultural conventions, which vary by time and place.

And of course, God is the ground of this hierarchy of objective moral absolutes. They existed through him before human beings even appeared, as part of his design for us, his creatures. How we ought to behave is grounded ontologically in God’s design for us.

Atheist gets her PhD in astronomy and astrophysics and finds evidence for God

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

Christian apologist Terrell Clemmons tweeted this testimony by Sarah Salviander, a research scientist in astronomy and astrophysics at the prestigious University of Texas at Austin.

Dr. Salviander writes:

I was born in the U.S., but grew up in Canada. My parents were socialists and political activists who thought British Columbia would be a better place for us to live, since it had the only socialist government in North America at the time. My parents were also atheists, though they eschewed that label in favor of “agnostic.” They were kind, loving, and moral, but religion played no part in my life. Instead, my childhood revolved around education, particularly science. I remember how important it was to my parents that my brother and I did well in school.

I just want to point out that I hope that all you Christian parents are taking seriously the obligation to make your kids do well in school, because even if they start out as atheists when they are young, they can still find their way back to God through study, as Sarah did.

She had a bad start, that’s for sure:

I grew up in the 1970s and 1980s, a time when science fiction was enjoying a renaissance, thanks largely to the popularity of Star Wars. I remember how fascinated I was by the original Star Wars trilogy. It had almost nothing to do with science—it’s more properly characterized as space opera—but it got me thinking about space in a big way. I also loved the original Star Trek, which was more science fiction. The stoic and logical character of Mr. Spock was particularly appealing to me. Popular science was also experiencing a renaissance at that time, which had a lot to do with Carl Sagan’s television show, Cosmos, which I adored. The combination of these influences led to such an intense wonder about outer space and the universe, that by the time I was nine years old I knew I would be a space scientist someday.

Canada was already post-Christian by the 1970s, so I grew up with no religion. In retrospect, it’s amazing that for the first 25 years of my life, I met only three people who identified as Christian. My view of Christianity was negative from an early age, and by the time I was in my twenties, I was actively hostile toward Christianity. Looking back, I realized a lot of this was the unconscious absorption of the general hostility toward Christianity that is common in places like Canada and Europe; my hostility certainly wasn’t based on actually knowing anything about Christianity. I had come to believe that Christianity made people weak and foolish; I thought it was philosophically trivial. I was ignorant not only of the Bible, but also of the deep philosophy of Christianity and the scientific discoveries that shed new light on the origins of the universe and life on Earth.

She documents a phase of following Ayn Rand and embracing “Objectivism”, but eventually she rejects it for failing to answer the big questions of life.


I began to focus all of my energy on my studies, and became very dedicated to my physics and math courses. I joined campus clubs, started to make friends, and, for the first time in my life, I was meeting Christians. They weren’t like Objectivists—they were joyous and content. And, they were smart, too. I was astonished to find that my physics professors, whom I admired, were Christian. Their personal example began to have an influence on me, and I found myself growing less hostile to Christianity.

This is why I think it is so important for Christian parents to raise their children to get advanced degrees… either to become professors themselves, or to finance others (e.g. – our own children) to do advanced degrees. It is so important for university students to see Christian professors on campus. And failing that, it’s important that we bring Christian speakers in to debate non-Christian speakers on the important issues. This will not happen unless we recognize how important it is, and then make a plan to achieve it.


I had joined a group in the Center for Astrophysics and Space Sciences (CASS) that was researching evidence for the big bang. The cosmic background radiation—the leftover radiation from the big bang—provides the strongest evidence for the theory, but cosmologists need other, independent lines of evidence to confirm it. My group was studying deuterium abundances in the early universe. Deuterium is an isotope of hydrogen, and its abundance in the early universe is sensitive to the amount of ordinary mass contained in the entire universe. Believe it or not, this one measurement tells us whether the big bang model is correct.

If anyone is interested in how this works, I’ll describe it, but for now I’ll spare you the gruesome details. Suffice it to say that an amazing convergence of physical properties is necessary in order to study deuterium abundances in the early universe, and yet this convergence is exactly what we get. I remember being astounded by this, blown away, completely and utterly awed. It seemed incredible to me that there was a way to find the answer to this question we had about the universe. In fact, it seems that every question we have about the universe is answerable. There’s no reason it has to be this way, and it made me think of Einstein’s observation that the most incomprehensible thing about the world is that it’s comprehensible. I started to sense an underlying order to the universe. Without knowing it, I was awakening to what Psalm 19 tells us so clearly, “The heavens declare the glory of God; the skies proclaim the work of his hands.”

That summer, I’d picked up a copy of The Count of Monte Cristo by Alexandre Dumas and was reading it in my off hours. Previous to this, I’d only known it as an exciting story of revenge, since that’s what the countless movie and TV adaptations always focused on. But it’s more than just a revenge story, it’s a philosophically deep examination of forgiveness and God’s role in giving justice. I was surprised by this, and was starting to realize that the concept of God and religion was not as philosophically trivial as I had thought.

All of this culminated one day, as I was walking across that beautiful La Jolla campus. I stopped in my tracks when it hit me—I believed in God! I was so happy; it was like a weight had been lifted from my heart. I realized that most of the pain I’d experienced in my life was of my own making, but that God had used it to make me wiser and more compassionate. It was a great relief to discover that there was a reason for suffering, and that it was because God was loving and just. God could not be perfectly just unless I—just like everyone else—was made to suffer for the bad things I’d done.

The Count of Monte Cristo is one of my favorite, favorite books as well, and had the same impact on me as it did on her.

OK, that’s enough for this post. Go read the rest, and please share it.

I spoke to her recently and she told me that she is working on several projects that are designed to get people more familiar with science and Bible issues. This woman is an expert Christian apologist and her life will have an influence. Are you going to be like her? Will you mentor others to be like her? Will you marry someone like her? Will you raise children who are like her? I think we should all have a plan to study the areas that are important and have an influence for God with what we learn.

Positive arguments for Christian theism

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.

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.
