Does "Progress" Trump Faith?

"All science proceeds on the assumption that nature is ordered in a rational and intelligible way. You couldn't be a scientist if you thought the universe was a meaningless jumble of odds and ends haphazardly juxtaposed... to be a scientist, you had to have faith that the universe is governed by dependable, immutable, absolute, universal, mathematical laws of an unspecified origin." ~ Paul Davies

Today Fox News published an article called "Science vs. god: does progress trump faith?" discussing some of the high points between a debate over the existence of God between a set of scientists. It poses the question: "Does science refute religion?", and then points out that three out of five scientists are atheists but that of course means that two out of five are not, showing there is no "consensus" like some claim, at least on the question of God.

I do not have a lot of time to write a full response, especially since I have written about a lot of these issues before, but I wanted to point out a few things. First, as the quote above from Paul Davies' (an atheist) comments, there is faith in science. As I have written about here, here, here, and here, science is far from the purely "objected" and "empirical" tool that atheists claim it is. Now, those of you who know me know I love science and think highly of its ability, but we have to call a spade a spade, it takes faith to do the scientific enterprise. And, those who believe that science is the end-all-be-all of understanding reality are as religious as the most fundamental Christian.

Second, one of the scientists in the debate, Lawrence Krauss (whose book The Physics of Star Trek is awesome, by the way), stated, "Science has taught us we don't need God to exist..." Stephen Hawking's book, The Grand Design was cited as an example of this. That is simply not the case. I have written about that here and here.

Third, the article also states, "Proponents for religion argue that the universe is finely tuned for life, with certain fundamental parameters in nature that make our existence possible. But Krauss turned this argument on its head. 'We would be surprised to find ourselves in a universe in which we couldn't live,' Krauss said." They are trying to make the point that "of course" we live in a universe finely tuned because that is the only universe that would support life. This statement, however, rests on the presupposition that there are many universes in the "multiverse" (which is far from an universally accepted scientific theory) most of which do not have any possibility for life and we find ourselves in the one that "by chance" evolved all the right parameters. If you have enough universes, eventually one will be right for life, right? This is a sophisticated argument but it in no way shows God does not exist or that science does not take its fundamental laws by faith. Paul Davies (another atheist scientist at Arizona State) states in an article that he wrote for the New York Times:
A second reason that the laws of physics have now been brought within the scope of scientific inquiry is the realization that what we long regarded as absolute and universal laws might not be truly fundamental at all, but more like local bylaws. They could vary from place to place on a mega-cosmic scale. A God’s-eye view might reveal a vast patchwork quilt of universes, each with its own distinctive set of bylaws. In this “multiverse,” life will arise only in those patches with bio-friendly bylaws, so it is no surprise that we find ourselves in a Goldilocks universe — one that is just right for life. We have selected it by our very existence.
The multiverse theory is increasingly popular, but it doesn't so much explain the laws of physics as dodge the whole issue. There has to be a physical mechanism to make all those universes and bestow bylaws on them. This process will require its own laws, or meta-laws. Where do they come from? The problem has simply been shifted up a level from the laws of the universe to the meta-laws of the multiverse.
As he states, the idea that Krauss and others put forward is really just skirting the issue. It pushes it back a level, but it is still there. They have in no way shown that science is not taken on faith and that God is not necessary for our universe. For some more reading on this, I would recommend two books: Why the Universe Is the Way It Is and Who's Afraid of the Multiverse? Both are excellent resources in this area. I would also recommend Jeff Zweerink series of articles on "Multiverse Musings."

I will leave it at that. I do not want to make your head explode, nor do I have the time to keep writing (have a sermon on which I should be working). This should give you enough food-for-thought for a while on the whole subject of "science vs. religion" and whether or not science, the physical laws, and the universe can exist without God.

The Beginning of the Universe

"He asserts that the universe came from 'nothing' rather than from God. However, the different 'nothings' that Krauss appeals to for his explanations are really 'some things'—'some things' that demand nothing less than the existence and involvement of the biblical God." ~ Dr. Hugh Ross, "Universe from Nothing?: A Critique of Lawrence Krauss' Book, Part 1"

Another set of Big Bang news articles have hit the popular media. This time with headlines like "The Big Bang Didn't Need God to Start Universe, Researchers Say." This is similar to what Stephen Hawking wrote in his book The Grand Design, which I wrote about a while ago. The impetus behind such assertions is the desire to remove God from the equation when it comes to the origins of the universe. This has been a problem for naturalistic scientists ever since the first indications that the universe is expanding. So, let's talk about Big Bang cosmological theory and see if the above claims stand up within that framework.

Why is this such a big deal to Big Bang cosmologists? Well, it is often believed that "Big Bang" automatically means an atheistic world-view, but, while that may seem to be common now, that was not the original response to Big Bang cosmology. In fact, the Big Bang was originally seen by steady-state cosmologists as an inherently religious idea. Geoffrey Burbidge, for example, once lamented that his fellow scientists were running off to join the "First Church of Christ of the Big Bang." Sir Fred Hoyle first coined the phrase "Big Bang" in a 1949 BBC broadcast as a pejorative name because of its religious significance (though he did later recant). Why did they see it as religious? Because saying that the universe has a beginning means that it must have had a Beginner, and they did not want to admit the possibility of a Beginner.

Recently, however, many noted scientists have begun theorizing how the universe could have created itself from nothing. That is, of course, the holy grail of a naturalistic world-view--if you can show that the universe did not need a Beginner, then God is not necessary (at least, that is the assumption). So, we get articles like the one list above and books like Hawking's The Grand Design. As I have already written about Hawking's work, I will make a few comments about the recent articles.

The basic premise of such arguments is that "the Big Bang could've occurred as a result of just the laws of physics being there. With the laws of physics, you can get universes." What I find most interesting about this is that the scientist quoted (Alex Filippenko of the University of California, Berkeley) admits that the laws of physics cannot explain themselves. He even admits that they would require a divine Creator, though he goes on to ask who created the divine Creator, which he believes leads to a never-ending chain of causes. But does it really? Basically, Filippenko is showing the validity and necessity of the Kalam Cosmological Argument, which is a classic argument for an uncaused Cause or a Creator. Eventually the chain of causality throughout the history of being has to have a beginning. String Theory posits a type of multiverse to explain the beginning of our universe. Filippenko and Hawking posit that the laws of physics cause the universe to create itself. Both of these simply push the need for a Creator back a step. They simply add another link to the chain of causality. Where did the multiverse come from? Where did the laws of physics come from? Believing they are simply "brute realities" takes as much faith as, if not more than it takes to believe in a Creator (I have written about this here, here, here, and here). Such theories do not solve the problem but are basically mathematical ways of skirting the question.

Furthermore, Filippenko positing quantum fluctuations as a creative event has problems. (Warning, this is going to get a little bit technical.) A consequence of the uncertainty principle in quantum mechanics is that quantum fluctuations in the fabric of space-time will generate particles out of "nothing" (it is not really nothing as we will soon see). Seth Shostack from SETI asserts, "Quantum mechanical fluctuations can produce the cosmos." In the article, Filippenko draws on this idea and says, "If you would just, in this room, just twist time and space the right way, you might create an entirely new universe. It's not clear you could get into that universe, but you would create it." The first problem with this, that is not mentioned in the articles, is that while the uncertainty principle allows for the random creation of particles, it also requires that these particles revert back to fluctuations before they can be observed. They will not stick around long enough to create anything, about a quintillionth of a second (that is 0.000000000000000001 seconds)! The second problem is even larger than the first. The article and the scientists call this creation from nothing but it is in no way creation from nothing. It is creation from other "some things" (as the quote from Dr. Hugh Ross above states). When he says, "If you would just, in this room, just twist time and space the right way..." Filippenko reveals a major problem in his theory: quantum fluctuations require space-time (which is something, not nothing) to already exist for any type of particles (or universes) to be created. Rather than coming from nothing, they come from pre-existent physical laws and pre-existent space-time. Space-time must already exist for quantum fluctuations to create anything. So, one must again ask, "Has the need for a divine Creator really been removed from the situation?" Not hardly. If the fabric of space-time is necessary for quantum fluctuations to create anything, then space-time first had to be created by something or Someone else. Again, this pushes the need for a Creator back a step but in no way rids us of that need.

For more on this topic, I would suggest you read Dr. Hugh Ross' review of Lawrence M. Krauss' book A Universe from Nothing. Krauss' book is a much more highly developed argument than the article I have been citing or even Hawking's book. Dr. Hugh Ross does a very good job of laying out the issues with it in part 1 and the theological explanations in part 2.

Hawking's God

"But contrary to what Hawking claims, physical laws can never provide a complete explanation of the universe. Laws themselves do not create anything, they are merely a description of what happens under certain conditions." Dr. John Lennox, Professor of Mathematics at the University of Oxford, writing for Mail Online

Recently Stephen Hawking, while promoting his new (yet-to-be-published) book The Grand Design, has made a few highly controversial statements. In an interview Hawking stated, "Because there is a law such as gravity, the Universe can and will create itself from nothing... Spontaneous creation is the reason there is something rather than nothing, why the Universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the Universe going." Dr. Lennox responded to Hawking's statement in an article for Mail Online where he says what I have quoted above. I wanted to write about this because I both agree and disagree with Dr. Lennox. I agree with him in that physical laws can never provide a complete explanation of the universe and that laws, of course, do not create anything. In his article, Dr. Lennox goes onto say, "What Hawking appears to have done is to confuse law with agency. His call on us to choose between God and physics is a bit like someone demanding that we choose between aeronautical engineer Sir Frank Whittle and the laws of physics to explain the jet engine." This is where I disagree with him. I do not think that Hawking is confusing law with agency but attributing agency to the laws of physics, replacing a personal God with impersonal laws.

Many years ago in A Brief History of Time (BHT) Hawking stated, "If we discover a complete theory it would be the ultimate triumph of human reason for then we would know the mind of God." When Hawking wrote BHT he seemed to be your average deist who does not believe in a personal God but believes that some transcendent being is necessary for creating the laws of physics and mathematics. In his recent statements, Hawking appears to have changed his theology about God. This is what is creating all the hype about this book. But has he (this is the way Dr. Lennox interprets it) or is he now just being more explicit about who, or what, this "God" is? I believe it is the latter. I do not think that Hawking has changed his theology at all but is being much more explicit than he was in BHT. Now he is specifically stating that a personal God does not exist but that the laws of physics are "God". Look at what he says, "Because there is a law such as gravity..." (emphasis mine). He is not eliminating a need for a first cause (see the Kalam Cosmological Argument) but treating the laws of physics as a brute reality, a transcendent cause that is preexistent. To Hawking, "God" is the laws of physics.

Why is he doing this? Well, again, I believe we can see that in his statement in BHT as well as his recent statements. In BHT he says that discovering a complete theory would allow us to "know the mind of God." In his new book Hawking is proposing a way of looking at the universe where it would be possible for a human to know everything there is to know about the universe (a theory of everything (TOE)). Now we can see what is driving Hawking. If God is personal and transcendent, then the idea that we could come up with a TOE that shows us "the mind of God" is impossible. For example, science would not be able to answer the question of why the universe exists in the first place. However, if "God" is an impersonal set of physical laws that are simply a brute force of reality with no basis (a god) then a TOE is possible. Hawking is picking one cosmological and theological model over another so that it would be possible for him to have a complete theory of everything.

Hawking, like all human beings do at one point or another, has fallen prey to the original temptation of satan. How does satan tempt Eve in the Garden of Eden? "'You will not surely die,' the serpent said to the woman. 'For God knows that when you eat of it your eyes will be opened, and you will be like God...'" (Genesis 3:4-5). In order to know what God knows, Eve disobeyed the one command He gave Adam and her by eating the fruit. In order to know what God knows, Hawking is taking a theological world-view, which holds that "God" is an impersonal set of physical laws that transcend the universe.

There is a very big problem with what Hawking is doing here, however. The laws of physics constantly remind all scientists that effect cannot be greater than the cause, the lesser cannot produce the greater. How can an impersonal set of laws (the lesser) produce personal beings like humans (the greater)? Why is it that humans have personality, compassion, or relationships? Hawking's TOE cannot answer this question because the impersonal cannot beget the personal. To put the problem in another way that philosopher Kenneth Samples has put it, "How is it that the universe can create beings that can understand the universe but the universe cannot understand itself?" If the universe generates us and we can understand the universe but the universe cannot understand us then we are greater than the universe. This is counter to the laws of physics. Impersonal laws (Hawking's "God") can only produce impersonal results such as planets and stars, but they cannot produce personal, compassionate, relational beings like us.
