07.14.2010 – A Fine-Tuned Universe?

I find myself intrigued by the various arguments for and against God. Lately, I’ve been considering the Fine-Tuning argument (a subset of the Teleological Argument). In a nut-shell, it goes like this:

The Fine-Tuning argument is a modern variant on the overall Teleological argument and is based on the anthropic principle. The anthropic principle deals with the seemingly delicate balance of conditions that are necessary in order to support human life. It finds its evidence mostly in the vast improbabilities that the universe would find the conditions that it has in order to produce human life. And because these improbabilities are so vast, that leads to the assumption that a designer needed to be present.

I’m not going to get into the specific numbers of this argument (they are, after-all incomprehensibly large), because the refutations to those are out there to be had (basically, life DID occur in this universe, so the probability is technically negligible and there’s nothing that we know of to measure it against. ie…a universe that did NOT produce life). What I DO want to discuss, though, is MY take on it. It may not be scholarly, or based on any kind of scientific data or research, but I believe it to be based on some common sense. And, as always, I’m open to other people’s takes on the topic.

What we see in the observable universe are mind-bending amounts of empty, black space. Vast areas of absolutely nothing in the Cosmos. And in all that space and time, to the best of our limited knowledge, WE are the only life that has developed in this universe (though, I fully expect in the coming years, decades, and centuries that may change, but for the time-being I must rely on reality, and reality is, we are all we know of). My trouble with the fine-tuning argument is this: If the universe is fine-tuned for human life, why are we the ONLY human life in an unbelievably enormous universe? Doesn’t it seem like an awfully huge waste of energy and matter in the universe to have only us here, on this tiny ‘Pale Blue Dot’ in the arm of an otherwise ordinary spiral galaxy? If the universe was fine-tuned for human life, shouldn’t it be absolutely bursting at the seams with human beings? It seems that if it WAS designed, it wasn’t done so very efficiently and that doesn’t seem like the modus operandi of an all-powerful, eternal engineer.

Now, I’m obviously not a scientist. I’m not even all that smart of a guy. I get that the constants in the universe, and the coincidences in the numbers are impressive. I also understand that even the slightest changes in those numbers could have resulted in a lifeless universe. However, reality is what it is. The universe has produced intelligent life. But how many other universes are out there that are completely void of life? We will probably never know.

I’m just starting my deep investigation of these claims, so I expect that I will post more on the topic as I learn and dig into the various explanations. And a lot of times I feel like I don’t have a clue what some of these arguments are talking about. But I’m making progress, and while sometimes they give me pause, ultimately, I’m secure in my belief set.
