Is the Big Bang cosmology a theistic or atheistic theory of cosmic origins?

Dr. Michael Strauss is a practicing particle physics employed as a professor at University of Oklahoma. He does research in particle physics at CERN, a large hadron collider. It’s safe to assume that he knows something about experimental physics.

Here’s what he writes about Christians and the Big Bang at his new blog:

When my children were young, I would often drive to the home of the person babysitting my kids, usually a young teenage girl, pick her up, then drive her back to my house.  In the car I would ask questions about her interests or her school.  In addition, I would sometimes ask a question that intrigued me since I am a scientist and a Christian, “Do you think the Big Bang is a theistic theory or an atheistic theory?”  Now that question is not on most people’s list of babysitter interview questions, but I was interested to know their answer even though it would not affect their monetary tip. Every time I asked this question I always got the same answer, that the Big Bang is an atheistic theory.  This is just one example of the fact that many kids growing up in an evangelical church environment have the perception that the Big Bang is an idea which removes God as the creator.  It seems that many Christians may disdain the Big Bang.

Subsequent conversations with people of all ages have shown me that many individuals (1) don’t really understand what the Big Bang is, (2) don’t know the scientific evidence for the Big Bang, and (3) don’t comprehend the theistic significance of the Big Bang.   So let’s explore these ideas a little bit.

Here is his overview of the scientific evidence for the Big Bang:

There are three primary observations that are best explained by the Big Bang.  First, the universe is expanding so that it must have had a beginning of expansion in the past.  Second, because the universe was once very hot, we can still see the remnants of that heat in the Cosmic Microwave Background (CMB) radiation.  The latest measurements of the CMB spectrum made by the Planck satellite (shown above) agrees almost perfectly with theoretical calculations using the standard Big Bang cosmological model (see the plot at the end of this post).  Third, the theory predicts the amount of primordial light elements that should have been created in the first few minutes of the Big Bang, like hydrogen and helium.  Again the observations and the theoretical calculations align almost exactly.   A few other observations are supported by Big Bang predictions, like the distribution of galaxies and primordial gas.  The agreement between what we measure and what is expected from a Big Bang is so remarkable that just about all scientists accept the Big Bang as the origin of our universe, despite its implication that the universe had a beginning.

Does this scientific evidence support theism, or atheism?

Because we don’t have any observations that tell us exactly what happened “in the beginning” of our universe, we can only speculate.  But let me point out the obvious.  All of the observations we do have, and all the theoretical calculations, and even some projective calculations like the Borde-Guth-Vilenkin theorem (which I should probably blog about at some time) give credence to the conclusion that all of the space, time, matter, and energy of this universe had a beginning.  The Big Bang is a misnomer for it is not some kind of explosion since there was nothing that existed to explode.  It is the origin of the universe.  So if this universe had a beginning, then the cause of the universe can not be a part of the universe.  The cause must be transcendent, like the Christian idea of God.  Is the fact that all the evidence points to our universe having a transcendent cause proof for God?  No, but it is extremely powerful evidence.  If one hundred years ago you had predicted that scientists would obtain unambiguous evidence about the history of the universe for 13.8 billion years, all of its lifetime except the first fraction of a second, and that all of the evidence would point to an actual beginning consistent with a transcendent cause, I don’t think anyone would have taken you seriously.  But that is exactly what has happened.  Theists could not have outlined a better scenario to support theism.  The scientific facts are completely consistent with the statement, “In the beginning God created the heavens and the earth.”

Now I’ve had conversations with atheists about this scientific evidence during my lifetime. And the conversations always go like this: I lay out the experimental evidence and theoretical evidence for a cosmic beginning, and they start to talk about science fiction: Star Wars and Star Trek. But there are also famous atheists who have tried to account for the Big Bang cosmology in their atheistic worldview.

Here’s Oxford University professor of physical chemistry (and atheist) Peter Atkins explaining how he grounds the Big Bang cosmology:

Easy! Nothing actually exists, according to Peter Atkins.

What about a theoretical physicist, like Lawrence Krauss? Well, he just redefines the nothing that causally preceded the origin of the universe so that it is actually something. Pure speculation, and it goes against the experimental scientific evidence we have. Exactly what you’d expect from a man who wrote a book about the physics of “Star Trek”.

You don’t get to start with the laws of physics in the Big Bang cosmology. You don’t get to start with an electron. You don’t get to start with a quantum vacuum, nor even quantum foam. You start with nothing: no matter, no energy, no space, and no time. From that state, the universe begins to exist. Atheists hate the Big Bang cosmology. And they also hate the fine-tuning of the initial conditions of the Big Bang that allows the universe to support complex, embodied intelligent life. (Another miraculous evidence for God that is opposed by the anti-science fundamentalists).

I see resistance against the use of scientific evidence to support the existence of God from many pious pastors like Al Mohler, Russell Moore, etc. Some pastors think that you can just read the Bible out loud to someone and it will convert them to Christianity, as if the words of the Bible, in and of themselves, were some sort of incantation. It’s sort of like the “burning of the bosom” that Mormons are supposed to have when reading the Mormon Bible, which Mormons use in place of evidence, since they don’t have any. Many fideist pastors adopt this Mormon approach to trusting in God. Never mind that Jesus offered his resurrection as evidence of his claims to divinity to skeptics. Apparently, These pious pastors know better than Jesus how to evangelize non-Christians, and they’ve decided that the magic words fideist approach is better than use of scientific and historical evidence. It’s really annoying that the pious pastors have so much more influence in churches than the witness of experimental science, which is just God speaking to us through nature. I’d trust scientific evidence over an uneducated fundamentalist pastor any day of the week.

William Lane Craig and atheist Daniel Dennett discuss cosmology and fine-tuning

Here is audio of a very interesting exchange between William Lane Craig and leading atheist Daniel Dennett.

This audio records a part of the Greer-Heard debate in 2007, between prominent atheist Daniel Dennett and lame theistic evolutionist Alister McGrath. Craig was one of the respondents, and this was the best part of the event. It is a little bit advanced, but I have found that if you listen to things like this over and over with your friends and family, and then try to explain it to non-Christians, you’ll get it.

By the way, this is mostly original material from Craig, dated 2007, and he delivers the speech perfectly, so it’s entertaining to listen to.

Craig presents three arguments for a Creator and Designer of the universe:

  • the contingency argument
  • the kalam cosmological argument
  • the teleological argument

He also discusses Dennett’s published responses to these arguments, and that’s what I want to focus on, since most of you are already familiar with Craig’s philosophical arguments for the existence of God.

Dennett’s response to Craig’s paper

Here is my snarky paraphrase of Dennett’s reponse: (this is very snarky, because Dennett was just awful)

  • Craig’s three arguments are bulletproof, the premises are plausible, and grounded by the best cutting edge science we know today.
  • I cannot find anything wrong with his arguments right now, but maybe later when I go home it will come to me what’s wrong with them.
  • But atheism is true even if all the evidence is against it today. I know it’s true by my blind faith.
  • The world is so mysterious, and all the science of today will be overturned tomorrow so that atheism will be rational again. I have blind faith that this new evidence will be discovered any minute.
  • Just because the cause of the beginning of time is eternal and the cause of the beginning of space is non-physical, the cause doesn’t have to be God.
  • “Maybe the cause of the universe is the idea of an apple, or the square root of 7”. (HE LITERALLY SAID THAT!)
  • The principle of triangulation might have brought the entire physical universe into being out of nothing.
  • I don’t understand anything about non-physical causation, even though I cannot even speak meaningful sentences unless I have a non-physical mind that is causing my body to emit the meaningful sentences in a non-determined manner.
  • Alexander Vilenkin is much smarter than Craig and if he were here he would beat him up good with phantom arguments.
  • Alan Guth is much smarter than Craig and if he were here he would beat him up good with phantom arguments.
  • This science stuff is so complicated to me – so Craig can’t be right about it even though he’s published about it and debated it all with the best atheists on the planet.
  • If God is outside of time, then this is just deism, not theism. (This part is correct, but Craig believes that God enters into time at the moment of creation – so that it is not a deistic God)
  • If deism is true, then I can still be an atheist, because a Creator and Designer of the universe is compatible with atheism.
  • I’m pretty sure that Craig doesn’t have any good arguments that can argue for Christianity – certainly not an historical argument for the resurrection of Jesus based on minimal facts, that he’s defended against the most prominent historians on the planet in public debates and in prestigous books and research journals.

This is a very careful treatment of the arguments that Dr. Craig goes over briefly during his debates. Recommended.

Positive arguments for Christian theism

Harvard University astrophysicist discusses fine-tuning in the Washington Post

I’m pretty sure my readers already know about the fine-tuning argument, but it’s not every day you see it discussed (however briefly) in a far-left mainstream newspaper like the Washington Post. (H/T Carmen)

The author is Howard A. Smith:

Howard A. Smith is a senior astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, and a member of the Harvard Department of Astronomy. His research emphasizes the origins of stars, stellar systems and galaxies, and he is an author on more than 250 scientific articles. Previously he was Chair of Astronomy at the Smithsonian’s National Air and Space Museum; he also served for three years as a visiting scientist at NASA Headquarters.

Here is some of what he wrote in the far-left Washington Post:

There was a time, back when astronomy put Earth at the center of the universe, that we thought we were special. But after Copernicus kicked Earth off its pedestal, we decided we were cosmically inconsequential, partly because the universe is vast and about the same everywhere. Astronomer Carl Sagan put it this way: “We find that we live on an insignificant planet of a humdrum star.” Stephen Hawking was even blunter: “The human race is just a chemical scum on a moderate-sized planet.”

An objective look, however, at just two of the most dramatic discoveries of astronomy — big bang cosmology and planets around other stars (exoplanets) — suggests the opposite. We seem to be cosmically special, perhaps even unique — at least as far as we are likely to know for eons.

The first result — the anthropic principle — has been accepted by physicists for 43 years. The universe, far from being a collection of random accidents, appears to be stupendously perfect and fine-tuned for life. The strengths of the four forces that operate in the universe — gravity, electromagnetism, and the strong and weak nuclear interactions (the latter two dominate only at the level of atoms) — for example, have values critically suited for life, and were they even a few percent different, we would not be here. The most extreme example is the big bang creation: Even an infinitesimal change to its explosive expansion value would preclude life. The frequent response from physicists offers a speculative solution: an infinite number of universes — we are just living in the one with the right value. But modern philosophers such as Thomas Nagel and pioneering quantum physicists such as John Wheeler have argued instead that intelligent beings must somehow be the directed goal of such a curiously fine-tuned cosmos.

It seems likely that exoplanets could host extraterrestrial intelligence. But intelligence is not so easy to produce. Paleontologist Peter Ward and astronomer Donald Brownlee summarize the many constraints in their book “Rare Earth: Why Complex Life is Uncommon in the Universe ” and show why it takes vastly more than liquid water and a pleasant environment to give birth even to simple (much less complex) life. At a minimum, it takes an environment stable for billions of years of evolution, plus all the right ingredients. Biologists from Jacques Monod to Stephen Jay Gould have emphasized the extraordinary circumstances that led to intelligence on Earth, while geneticists have found that DNA probably resulted from many accidents. So although the same processes operate everywhere, some sequences could be unlikely, even astronomically unlikely. The evolution of intelligence could certainly be such a sequence.

There is, moreover, a well-known constraint: the finite speed of light, which ensures that even over thousands of years we will only be able to communicate with the comparatively few stars (tens of millions) in our cosmic neighborhood. If the combined astronomical, biological and evolutionary chances for life to form and evolve to intelligence are only 1 in 10 million, then we probably have no one to talk to.

What is really strange is when I try to talk to atheists about this evidence, and they tell me about Star Trek and Star Wars and how the universe isn’t specially designed and there are aliens everywhere.  Atheists like the science fiction, they don’t like the science facts.

If you would like to hear a good lecture on the fine-tuning argument, this one with Robin Collins is very good. You can hear him debate the fine-tuning argument with Peter Millican here. And in this lecture Collins talks about his new research. Another discussion between Luke Barnes and an atheist is useful to understand how objections to the argument can be answered.
