This is the fifth in a series of guest blogs on science, religion, and design by Dr. Ben Clausen of the Geoscience Research Institute, based near the campus of Loma Linda University. The words that follow are his.
The evidence of fine-tuning has been explained naturalistically in various ways:
(1) Perhaps the fine-tuning of the constants is the only possible way that the laws of nature could exist (Weinberg 1992). Natural design happens all the time; take the intricate frost patterns for example, just based on the properties of water molecules.
(2) Perhaps it is not so much that the universe is finely adapted for life, but that life adapted itself to the universe through evolution, natural selection, and survival of the fittest. Organisms adapt to conditions, so perhaps other conditions than those on Earth could be adapted to by some form of life. The designer is just the environment.
(3) The Anthropic Principle is a suggested alternative to requiring a Designer (Carr and Rees 1979; Carter 1974; Barrow and Tipler 1986; Greenstein and Kropf 1989). The weak form of the principle states that: if the laws of the universe weren’t such as to allow life, we wouldn’t be here to notice, i.e., what we expect to observe is restricted by the conditions necessary for the presence of an observer. The Strong Anthropic Principle states that the laws of the universe necessarily must be such as to allow life. To many this explanation is lacking in appeal; it is like explaining why you can see an elephant in your living room by saying that you wouldn’t see it there if it wasn’t there.
The anthropic principle suggests that the laws are the way they are by chance and low probability events happen all the time. For example, the chance of you having your parents, being born where you were, and having the characteristics that you have is very small, but it happened. Any calculations concerning the likelihood of chance events are based on assumptions and changing the assumptions can profoundly change the calculated chances. Many features are necessary for life to exist on a particular planet, but with many planets orbiting many stars, it is possible that some might have the right conditions. In The Grand Design, Hawking and Mlodinow (2010) say, “In the same way that the environmental coincidences of the solar system were rendered unremarkable by the realization that billions of such systems exist, the fine-tunings in the laws of nature can be explained by the existence of multiple universes.”
(4) Infinite time and space have been suggested as possible explanations for the chance coincidences. Infinite time could be provided by multiple universes in series. Infinite space could be provided by having multiple universes in parallel. Perhaps many different universes exist in different spaces with different physical laws and we just happen to live in the one universe with the laws that make life possible. A multiverse was suggested by Hugh Everett in the 1950s to remove the strangeness of the observer effect in quantum mechanics. A non-observable universe has been suggested beyond what we can see out to 14 billion light years. And general relativity suggests additional dimensions beyond the three space dimensions that we observe. The multiverse concept is interesting, but beyond what science can observe.
Hawking explains the multiverse theory as Richard Feynman explains the quantum mechanical nature of light – just as light particles take multiple, in fact all possible, paths in the double slit experiment, the presence of “all possible universes” best explains the many options for choices in quantum theory (Bortz, 2010). M-theory allows 10500 universes, which would then allow for the possibility of different theories for each of the different universes. In The Grand Design, Hawking and Mlodinow (2010) explain that “according to quantum theory, the cosmos does not have just a single existence, or history, but rather that every possible history of the universe exists simultaneously … [Hawking and Mlodinow] question the conventional concept of reality, posing instead a ‘model-dependent’ theory of reality … the laws of our particular universe are extraordinarily finely tuned so as to allow for our existence … quantum theory predicts the multiverse–the idea that ours is just one of many universes that appeared spontaneously out of nothing, each with different laws of nature.” A universal inflation is continuing and verified, but the spawning of bubbles of space-time to make the multiverse is not really science, because it cannot be tested.
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. Naturalistic theory would tell us not to confuse law with agency (Lennox 2010). “Science doesn’t do ‘why’ – it does ‘how’” as Feynman warned (Turner 2010).
