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

9 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 article is posted online here.

Here’s an excerpt in which 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.

Now such a conclusion is profoundly disturbing for anyone who ponders it. For the question cannot be suppressed: Why does the universe exist rather than nothing? In light of the universe’s origin ex nihilo, one can no longer dismiss this question with a shrug and a slogan, “The universe is just there and that’s all.” For the universe is not “just there;” rather it came into being. The beginning of the universe discloses that the universe is not, as Hume thought, a necessarily existing being but is contingent in its existence. Philosophers analyzing the concept of necessary existence agree that the essential properties of any necessarily existing entity include its being eternal, uncaused, incorruptible, and indestructible{14}–for otherwise it would be capable of non-existence, which is self-contradictory. Thus, if the universe began to exist, its lacks at least one of the essential properties of necessary existence-eternality. Therefore, the reason for its existence cannot be immanent, but must in some mysterious way be ultra-mundane, or transcendent. Otherwise, one must say that the universe simply sprang into being uncaused out of absolutely nothing, which seems absurd. Sir Arthur Eddington, contemplating the beginning of the universe, opined that the expansion of the universe was so preposterous and incredible that “I feel almost an indignation that anyone should believe in it–except myself.”{15} He finally felt forced to conclude, “The beginning seems to present insuperable difficulties unless we agree to look on it as frankly supernatural.”{16}

I find that most scientists do not reflect philosophically upon the metaphysical implications of their theories. But, in the words of one astrophysical team, “The problem of the origin [of the universe] involves a certain metaphysical aspect which may be either appealing or revolting.”{17}

Every theist should 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
  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

Several naturalistic/materialistic cosmologies are refuted in Craig’s peer-reviewed paper, including the steady-state model, oscillating model, the vacuum fluctuation model, the chaotic inflationary model, and the quantum gravity model. These naturalistic (no God) alternatives all have theoretical or observational difficulties. Atheism is at odds with modern cosmology – and the progress of science itself.

This is the kind of evidence I expect all my readers to be using when discussing whether God exists. Scientific evidence. Please do not talk about your testimony, or the Bible, or what your pastor said on Sunday. We need to show that we understand science, because science is a reliable and respected way of getting knowledge about the universe. Science (experimental, testable, repeatable science) should set limits on what we can believe. Leave the wishing and hoping and praying and dreaming to the atheists.

You should definitely print this article out and read it, then send it to your atheistic friends. I have tried this out on atheists, and the response I get is that scientific discoveries will soon emerge that falsifies all of these six scientific discoveries, and the kalam cosmological argument, and will prove that the universe is eternal. When I ask them for reasons to believe that these discoveries will be forthcoming, they appeal to science fiction novels, television shows and movies. I will take a peer-reviewed research paper over Star Trek any day of the week.

Atheism hates science

How the progress of science strengthened the kalam cosmological argument

33 Comments

This is the first of a two-part series. Part two is here.

The kalam cosmological argument

The argument goes like this:

  1. Whatever begins to exist requires a cause
  2. The universe began to exist
  3. Therefore, the universe requires a cause.

The most important thing for you to realize is that nothing can be sustained in a debate unless it can be phrased as a valid argument according the rules of inference. All of Craig’s arguments can be broken down into logical propositions that use the standard laws of logical reasoning in order to force their conclusions deductively, so long as the premises are true.

Proving the premises

Can the atheist deny that either or both of these premises are true?

  1. “Whatever begins to exist requires a cause”
    If the atheist denies this premise, then they are denying a fundamental law of natural science, namely, that matter can neither be created or destroyed. That is natural law.
  2. “The universe began to exist”
    The universe came into being. If the atheist denies this they are denying the state of the art in modern cosmology.

Common objections

First, quantum mechanics is not going to save the atheist here. In QM, virtual particles come into being in a vacuum. The vacuum is sparked by a scientist. The particles exist for a period of time inversely proportional to their mass. But in the case of the big bang, there is no vacuum – there’s nothing. There is no scientist – there’s nothing. And the universe is far too massive to last 14 billion years as a virtual particle.

Secondly, atheists will say that the big bang is speculative physics that could change at any moment. But the trend is in favor of an absolute beginning out of nothing. We have had a string of solid, recent scientific discoveries that support the idea that the universe came into existence at some point in the finite past, as follows:

  • Einstein’s theory of general relativity, and the scientific confirmation of its accuracy
  • measurements of the cosmic microwave background radiation
  • red-shifting of light from galaxies moving away from us
  • radioactive element abundance predictions (from supernovae)
  • helium/hydrogen abundance predictions (nuclear fusion)
  • star formation and stellar lifecycle theories
  • the second law of thermodynamics

So, insofar as atheists question these discoveries and the origin of the entire physical universe out of nothing, they are opposing the progress of science.

What came into being at the moment of creation?

You need to understand that the big bang theory states that space, time and matter were all created at the moment of creation.

  1. There was no space causally prior to the universe beginning to exist
  2. There was no time causally prior to the universe beginning to exist
  3. There was no matter causally prior to the universe beginning to exist

All of these things began to exist at the first moment.

What can we infer about the cause?

So, space, time, and matter began to exist. What could have caused them to begin to exist?

  1. Whatever causes the universe to appear is not inside of space, because there was no space causally prior to the creation event. The cause must therefore be non-physical, because physical things exist in space.
  2. Whatever causes the universe to appear is not bound by time (temporal). It never began to exist. There was no passage of time causally prior to the big bang, so the cause of the universe did not come into being. The cause existed eternally.
  3. And the cause is not material. All the matter in the universe came into being at the first moment. Whatever caused the universe to begin to exist cannot have been matter, because there was no matter causally prior to the big bang.

So what could the cause be? Craig notes that we are only familiar with two kinds of non-material realities:

  1. Abstract objects, like numbers, sets and mathematical relations
  2. Minds, like your own mind

Now, abstract objects don’t cause of any effects in nature. But we are very familiar with the causal capabilities of our own minds – just raise your own arm and see! So, by process of elimination, we are left with a mind as the cause of the universe. As Sherlock Holmes says, “When you have eliminated the impossible, whatever remains, however improbable, must be the truth.”

This cause created the entire physical universe. The cause of this event is therefore supernatural, because it brings nature into being and is not inside of nature itself. The cause of the universe violates the law of conservation of matter is therefore performing a miracle.

Responding to alternative naturalistic cosmologies

In this published research paper from the journal Astrophysics and Space Science, William Lane Craig responds to the several naturalistic attempts to evade the implications of the kalam argument. I will list each one by name and explain the main problem with each. I highly recommend you read the paper and become conversant with the arguments and evidences.

  1. The steady-state model: disproved by recent empirical observations of radio galaxy distributions, as well as red-shifting of light from distant galaxies moving away from us at increasing speeds
  2. The oscillating model: disproved in 1998 by more empirical measurements of mass density which showed that the universe would expand forever, and never collapse (was named Discovery of the Year)
  3. The vacuum fluctuation model: the theory allows for universes to spawn at every point in space and coalesce into one extremely old universe, which contradictions observations of our much younger universe
  4. The chaotic inflationary model: does not avoid the need for an absolute beginning in the finite past
  5. The quantum gravity model: makes use of imaginary time which cannot be mapped into a physical reality, it’s purely theoretical

Comment warning

Everybody seems to like to comment on these things without making any claims or citing any authority or evidence. So if you are leaving a comment critical of this post, then cite the part you disagree with, quote someone who agrees with you who is an authority, and link to a piece of peer-reviewed evidence. I’d like to see some observations, please. Some data. If you cannot disagree with a specific point, and cite something specific to support you, then please – don’t leave a comment. Try to keep it short. I’ll delete any comments that go over 300 words, say.

If you would like me to cite some evidence for an assertion, you can leave a comment asking a question.

Further study

A good on this topic is the debate between William Lane Craig and atheist physicist Victor Stenger, (audio here). Also, a lecture titled “Beyond the Big Bang”, was delivered at the University of Colorado at Boulder, in front of Victor Stenger and other physicists (audio here). There is a period of Q&A in which Bill must face challengers. These are both available on DVD. More Bill Craig debates are here.

MUST-READ: Doug Groothuis explains how science confirms the beginning of the universe

Leave a comment

Post is here on the Constructive Curmudgeon.

No excerpt is possible, you must read the whole post.

Evidences cited for the origin of the universe (the Big Bang):

  • Einstein’s theory of general relativity (and experimental confirmation of the theory)
  • Hubble’s observations of red-shifted light from distant galaxies
  • Measurements of the cosmic microwave background radiation
  • Confirmed predictions of light element abundances (H and He abundances)
  • The second law of thermodynamics

When you present the kalam argument, you should present it exactly the way Doug does here. You should hang the entire argument on the progress of science. Once upon a time before science, there was ignorance. But now we know better, thanks to the progress of science. Science disproved atheism. Five times over.
