The kalam cosmological argument defended in a peer-reviewed science journal

3 Comments

Here’s the peer-reviewed article. It appears in a scientific journal focused on astrophysics.

Here’s the abstract:

Both cosmology and philosophy trace their roots to the wonder felt by the ancient Greeks as they contemplated the universe. The ultimate question remains why the universe exists rather than nothing. This question led Leibniz to postulate the existence of a metaphysically necessary being, which he identified as God. Leibniz’s critics, however, disputed this identification, claiming that the space-time universe itself may be the metaphysically necessary being. The discovery during this century that the universe began to exist, however, calls into question the universe’s status as metaphysically necessary, since any necessary being must be eternal in its existence. Although various cosmogonic models claiming to avert the beginning of the universe predicted by the standard model have been and continue to be offered, no model involving an eternal universe has proved as plausible as the standard model. Unless we are to assert that the universe simply sprang into being uncaused out of nothing, we are thus led to Leibniz’s conclusion. Several objections to inferring a supernatural cause of the origin of the universe are considered and found to be unsound.

The whole text of the article is posted online here.

Here’s an excerpt in which the author, Dr. William Lane Craig, explains the Big Bang cosmology:

The monumental significance of the Friedman-Lemaitre model lay in its historization of the universe. As one commentator has remarked, up to this time the idea of the expansion of the universe “was absolutely beyond comprehension. Throughout all of human history the universe was regarded as fixed and immutable and the idea that it might actually be changing was inconceivable.”{8} But if the Friedman-Lemaitre model were correct, the universe could no longer be adequately treated as a static entity existing, in effect, timelessly. Rather the universe has a history, and time will not be matter of indifference for our investigation of the cosmos. In 1929 Edwin Hubble’s measurements of the red-shift in the optical spectra of light from distant galaxies,{9} which was taken to indicate a universal recessional motion of the light sources in the line of sight, provided a dramatic verification of the Friedman-Lemaitre model. Incredibly, what Hubble had discovered was the isotropic expansion of the universe predicted by Friedman and Lemaitre. It marked a veritable turning point in the history of science. “Of all the great predictions that science has ever made over the centuries,” exclaims John Wheeler, “was there ever one greater than this, to predict, and predict correctly, and predict against all expectation a phenomenon so fantastic as the expansion of the universe?”{10}

As a GTR-based theory, the Friedman-Lemaitre model does not describe the expansion of the material content of the universe into a pre-existing, empty, Newtonian space, but rather the expansion of space itself. This has the astonishing implication that as one reverses the expansion and extrapolates back in time, space-time curvature becomes progressively greater until one finally arrives at a singular state at which space-time curvature becomes infinite. This state therefore constitutes an edge or boundary to space-time itself. P. C. W. Davies comments,

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.{11}

The popular expression “Big Bang,” originally a derisive term coined by Fred Hoyle to characterize the beginning of the universe predicted by the Friedman-Lemaitre model, is thus potentially misleading, since the expansion cannot be visualized from the outside (there being no “outside,” just as there is no “before” with respect to the Big Bang).{12}

The standard Big Bang model thus describes a universe which is not eternal in the past, but which came into being a finite time ago. Moreover,–and this deserves underscoring–the origin it posits is an absolute origin ex nihilo. For not only all matter and energy, but space and time themselves come into being at the initial cosmological singularity. As Barrow and Tipler emphasize, “At this singularity, space and time came into existence; literally nothing existed before the singularity, so, if the Universe originated at such a singularity, we would truly have a creation ex nihilo.“{13}

[…]On such a model the universe originates ex nihilo in the sense that at the initial singularity it is true that There is no earlier space-time point or it is false that Something existed prior to the singularity.

Every theist should be able to understand and defend this argument. It is a scientific refutation of materialism, and it is supported by six lines of scientific evidence – all of which emerged as science has progressed.

Scientific evidence:

  1. Einstein’s theory of general relativity (GTR)
  2. the red-shifting of light from distant galaxies implies an expanding universe
  3. the cosmic background radiation (which also disproves the oscillating model of the universe)
  4. the second law of thermodynamics applied to star formation theory
  5. hydrogen-helium abundance predictions
  6. radioactive element abundance predictions

Those are the scientific discoveries that have led us to the beginning of the universe, which support’s Dr. Craig’s argument.

Here’s a re-cap of the three main evidences for the Big Bang cosmology from Caltech. (Numbers 2, 3 and 5 from the list above)

Excerpt:

Until the early 1900s, most people had assumed that the universe was fixed in size. New possibilities opened up in 1915, when Einstein formulated his famous general relativity theory that describes the nature of space, time, and gravity. This theory allows for expansion or contraction of the fabric of space. In 1917, astronomer Willem de Sitter applied this theory to the entire universe and boldly went on to show that the universe could be expanding. Aleksandr Friedmann, a mathematician, reached the same conclusion in a more general way in 1922, as did Georges Lemaître, a cosmologist and a Jesuit, in 1927. This step was revolutionary since the accepted view at the time was that the universe was static in size. Tracing back this expanding universe, Lemaître imagined all matter initially contained in a tiny universe and then exploding. These thoughts introduced amazing new possibilities for the universe, but were independent of observation at that time.

Why Do We Think the Big Bang Happened?

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.”

The article goes into detail about each of these three evidences.

This is the kind of evidence I expect all Christian theists to be using when discussing the question of whether God exists. Scientific evidence. When talking to non-Christians, we first need to show that we understand science, because science is a reliable and respected way of getting knowledge about the universe. Non-Christians do not accept the Bible, but they do accept science, so we begin evangelism with science. Science (experimental, testable, repeatable science) should set limits on what anyone can believe – including non-Christians, who might otherwise not be inclined to listen to Bible verses and theology.

The Big Bang is not compatible with atheism

According to the Secular Humanist Manifesto, atheism is committed to an eternally existing universe, (See the first item: “Religious humanists regard the universe as self-existing and not created.”). If something non-material brought all existing matter into being, that would be a supernatural cause, and atheists deny that anything supernatural exists. The standard Big Bang theory requires that all the matter in the universe come into being out of nothing. This falsifies eternal models of the universe, which are required by the atheistic worldview.

You should definitely print out both articles and get familiar with the arguments and the evidence. I have tried this argument out on atheists, and the response I usually get is that scientific discoveries will soon emerge that falsifies all of these six scientific discoveries. That sounds more like faith than reason to me. And we have to make it clear to others who are still deciding that there is a conflict between science and religion. Just not the one they’re expecting. Let’s make our decisions about what to believe based on what science is telling us today. Let’s hold accountable people who want to have a worldview that is based on speculations.

Did the city of Nazareth exist at the time of the birth of Jesus?

Israeli archaeologist Yardena Alexandre inspects Roman 1st-century pottery found from the city of Nazareth.

I was discussing a recent debate that a friend attended between an atheist musician named Dan Barker and a Christian with a doctorate in New Testament Studies named Justin Bass.

According to my friend’s report, the atheist questioned the existence of Nazareth, and then went on from there to assert that everything we know about Jesus is legendary.

This is what the atheist’s argument sounds like:

  1. If the New Testament contains reliable history about Jesus, then Nazareth must exist.
  2. Nazareth does not exist.
  3. Therefore, the New Testaments does not contain reliable history about Jesus. (M.T. 1,2)

I was able to find a web site where an atheist was making the claim that Nazareth did not exist at the time of Jesus. So this is not completely outside the realm of mainstream atheism. I doubled checked with two more people who attended the debate that Barker indeed made an argument like the one above.

Two things to say about this 3-step argument. First off, when speaking to atheists, Christians only care about making a case for the resurrection. This is for two reasons. One, our goal is to disprove atheism, and the historical argument for the resurrection is the most evidenced miracle claim in the New Testament. Nazareth is not part of that core of minimal facts about the resurrection of Jesus. Second, it’s possible to be a Christian by accepting a core of Christian dogma (e.g. – the Apostle’s Creed), while remaining agnostic or even skeptical of other things in the Bible. Nazareth is not part of that core of minimal facts that must be affirmed in order to become a Christian.

The problem I have with atheists is that they pick and choose from the Bible according to their own agenda. Every Christian has read basic books on the resurrection by people like Lee Strobel, Michael Licona, William Lane Craig, J. Warner Wallace and so on. This is like table stakes for living a Christian life. We all know how to make a case based off of minimal facts for the resurrection. When Christians get into debates about Jesus, we want to make a case for the core of historical knowledge about him, minimal facts that almost no one disagrees with. But many atheists aren’t like that. They want to pick and choose a few verses out of the Old Testament and the New Testament that they personally find distasteful to them, and then deny the minimal facts about Jesus on that basis. I don’t think that it makes sense to deny evidence for widely-accepted facts by bringing up minor problems that are irrelevant to the well-attested core facts.

But it’s worse than that – we actually DO know that Nazareth existed, and we know it not from some fundamentalist preacher, but from atheist Bart Ehrman.

Ehrman writes in his book:

One supposedly legendary feature of the Gospels commonly discussed by mythicists is that the alleged hometown of Jesus, Nazareth did not exist but is itself a myth. The logic of this argument, which is sometimes advanced with considerable vehemence and force, appears to be that if Christians made up Jesus’ hometown, they probably made him up as well.  I could dispose of this argument fairly easily by pointing out that it is irrelevant.  If Jesus existed, as the evidence suggests, but Nazareth did not, as this assertion claims, then he merely came from somewhere else.  Whether Barack Obama was born in the U.S. or not (for what it is worth, he was) is irrelevant to the question of whether he was born.

Since, however, this argument is so widely favored among mythicists, I want to give it a further look and deeper exploration.  The most recent critic to dispute the existence of Nazareth is René Salm, who has devoted an entire book to the question, called The Myth of Nazareth.  Salm sees this issue as highly significant and relevant to the question of the historicity of Jesus: “Upon that determination [i.e., the existence of Nazareth] depends a great deal, perhaps even the entire edifice of Christendom.”

So that seems like a fair representation of the argument I outlined above.

Bart’s response is long, but here’s part of it:

There are numerous compelling pieces of archaeological evidence that in fact Nazareth did exist in Jesus’ day, and that like other villages and towns in that part of Galilee, it was built on the hillside, near where the later rock-cut kokh tombs were built.  For one thing, archaeologists have excavated a farm connected with the village, and it dates to the time of Jesus.  Salm disputes the finding of the archaeologists who did the excavation (it needs to be remembered, he himself is not an archaeologist but is simply basing his views on what the real archaeologists – all of whom disagree with him — have to say).  For one thing, when archaeologist Yardena Alexandre indicated that 165 coins were found in this excavation, she specified in the report that some of them were late, from the fourteenth or fifteenth centuries.  This suits Salm’s purposes just fine.  But as it turns out, there were among the coins some that date to the Hellenistic, Hasmonean, and early Roman period, that is, the days of Jesus.  Salm objected that this was not in Alexandre’s report, but Alexandre has verbally confirmed (to me personally) that in fact it is the case: there were coins in the collection that date to the time prior to the Jewish uprising.

Aalm also claims that the pottery found on the site that is dated to the time of Jesus is not really from this period, even though he is not an expert on pottery.  Two archaeologists who reply to Salm’s protestations say the following:  “Salm’s personal evaluation of the pottery … reveals his lack of expertise in the area as well as his lack of serious research in the sources.”  They go on to state: “By ignoring or dismissing solid ceramic, numismatic [that is, coins], and literary evidence for Nazareth’s existence during the Late Hellenisitic and Early Roman period, it would appear that the analysis which René Salm includes in his review, and his recent book must, in itself, be relegated to the realm of ‘myth.’”

Read Bart’s whole excerpt from his book in his post.

I did a quick double check on the archaeologist Ehrman mentioned, and found an Associated Press story about another archaelogical discovery made by archaeologists in Nazareth. This time, it’s not the coins, but pottery fragments. The date range on the pottery is 100 before Jesus’ birth to 100 years after Jesus’ birth.

Even though Ehrman is an atheist, I think that he understands how to do history. You can’t be a credentialed historian and throw out the early proclamation of Jesus’ resurrection because of doubts about Old Testament violence. You can’t be a credentialed historian and throw out the conversions of Paul and James because you don’t know whether there was one angel or two angels at the empty tomb. Denying the core facts about Jesus by bringing up concerns about peripheral issues is not a responsible way to investigate the historical Jesus.

One final point. This happens when discussing scientific evidence with atheists, too. I was discussing the scientific evidence for the origin of the universe and the cosmic fine-tuning with an atheist – mentioning names, dates and places related to the discoveries – and she cut me off with “Am I going to Hell?”

The importance of having a narrative when confronting the assumption of naturalism

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

How do you present theism as a rational belief to a person who thinks that the progress of science has removed the need for God?

Canadian science writer Denyse O’Leary writes about the history of cosmology at Evolution News.

Excerpt:

What help has materialism been in understanding the universe’s beginnings?

Many in cosmology have never made any secret of their dislike of the Big Bang, the generally accepted start to our universe first suggested by Belgian priest Georges Lemaître (1894-1966).

On the face of it, that is odd. The theory accounts well enough for the evidence. Nothing ever completely accounts for all the evidence, of course, because evidence is always changing a bit. But the Big Bang has enabled accurate prediction.

In which case, its hostile reception might surprise you. British astronomer Fred Hoyle (1915-2001) gave the theory its name in one of his papers — as a joke. Another noted astronomer, Arthur Eddington (1882-1944), exclaimed in 1933, “I feel almost an indignation that anyone should believe in it — except myself.” Why? Because “The beginning seems to present insuperable difficulties unless we agree to look on it as frankly supernatural.”

One team of astrophysicists (1973) opined that it “involves a certain metaphysical aspect which may be either appealing or revolting.” Robert Jastrow (1925-2008), head of NASA’s Goddard Institute for Space Studies, initially remarked, “On both scientific and philosophical grounds, the concept of an eternal Universe seems more acceptable than the concept of a transient Universe that springs into being suddenly, and then fades slowly into darkness.” And Templeton Prize winner (2011) Martin Rees recalls his mentor Dennis Sciama’s dogged commitment to an eternal universe, no-Big Bang model:

For him, as for its inventors, it had a deep philosophical appeal — the universe existed, from everlasting to everlasting, in a uniquely self-consistent state. When conflicting evidence emerged, Sciama therefore sought a loophole (even an unlikely seeming one) rather as a defense lawyer clutches at any argument to rebut the prosecution case.

Evidence forced theorists to abandon their preferred eternal-universe model. From the mid 1940s, Hoyle attempted to disprove the theory he named. Until 1964, when his preferred theory, the Steady State, lost an evidence test.

Here is a quick summary of some of the experimental evidence that emerged in the last few decades that caused naturalists to abandon the eternal universe that they loved so much when they were younger.

The importance of having a narrative

Now I want to make a very, very important point about Christianity and the progress of science. And that point is that it is very important that Christians present the evidence in exactly the way that Denyse presented it in that article – in its historical context, featuring the conflict between naturalists and the experimental evidence.

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

When you talk about these evidences as a Christian theist to non-Christians, you have to have cultivated a genuine interest in reconciling your beliefs with science. You have to accept that there are two books that reveal God’s character and attributes. The book of nature, and the book of Scripture. And you need to be flexible about getting these two books to fit together. The book of nature gives us natural theology (see Romans 1). It tells us that God is Creator and Designer. The book of Scripture tells us that God stepped into history as a man to save us by taking the punishment for our headlong rush away from God, which the Bible calls sin. Science is one way that humans can recover some of basic knowledge about God. Knowledge that is only possible because God created and designed the universe (and us) in such a way that we are capable of making discoveries, and that the universe is capable of being explored and understood.

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:

  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!

And now rational people – people who want to have true beliefs about reality – need to abandon a false religion (naturalism).

Now naturally, science is in a state of flux and things change. But you have to look at the trend of discoveries, and those trends are clearly going against naturalism, and in favor of Christian theism. No one is arguing for a deductive proof here, we are simply looking at the evidence we have today and proportioning our belief to the concrete evidence we have today. People who are guided by reason should not seek to construct a worldview by leveraging speculations about future discoveries and mere possibilities. We should instead believe what is more probable than not. That’s what a rational seeker of truth ought to do. Proportion belief to probabilities based on current, concrete knowledge.

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.

It falls to us Christian theists, then, to hold them accountable for their abuse and misrepresentation of science. And that means telling the story of the progress of science accurately, and accurately calling out the religion of naturalism for what it is – a religion rooted in blind faith and ignorance that has been repeatedly and convincingly falsified by the progress of science in the modern era.

Positive arguments for Christian theism
