Evidence Emerges That Laws of Physics Are Not Fine-Tuned For Life

Posted January 18, 2011 8:42 AM

From Technology Review RSS Feeds:

The value of the cosmological constant suggests that the laws of nature could not have been fine-tuned for life by an omnipotent being, says a cosmologist One of the more curious debates in science focuses on the laws of physics and why they seem fine-tuned for life.

Okay, so the current cosmological constant is not quite tweaked for the ultimate benefit for the evolution of life. At least that is the current evidence.

The claim is that if there was an omnipotent being, that being would have set the cosmological constant to it maximum beneficial value so that life has the best survival rate.

The observed constant is somewhat off of that optimum value, therefore, no omnipotent being is responsible for the observed universe.

Seems like a fallacy of logic to me. For example, the optimum biological conditions for my grass doesn't necessarily coincide with the optimal lawn when you consider one would be required to mow it more often.

I am not trying to argue for the existence or non-existance of God, but the logic precludes that one always strives for optimal conditions when in fact that may not be necessary or in some cases even desired.

GA. So now we have the Mildly Misanthropocentric Cosmological Principle. A just high enough value of the cosmological constant so life can exist without different species crowding each other out.

I like your grass analogy.

".. The observed constant is somewhat off of that optimum value, therefore, no omnipotent being is responsible for the observed universe .."

No, the argument isn't being used to disprove God/s but rather to disprove one of the arguments being used to support divine creation. There's a subtle difference.

I doubt the God/s debate will ever be settled using rational argument.

GA , Anon ...

... in spite of the fact that I am still somewhat befuddled, trying to determine whether you actually meant to say "presupposes" instead of "precludes" ... ?

Omnipotence means what it means! He is neither bound to "set" the rules such that they make sense to us, nor such that they achieve the 'perfection' or 'optimization' that *WE* see as right and proper. It was (argue as some may) His "plan" after all.

The idea that the cosmological constant, being a slightly "negative" for more opportunity of life, is based on what? If the CC, being slightly positive as we know it currently, leads to the detriment of life forming, how can we evaluate a slightly negative CC? It seems that a lot of assumptions have been declared as fact, and that is not science, but supposition.

But both faith, and evolution (in all it's forms) are based on supposition. Only faith, though, admits that it IS faith.

And as noted by implication above (I doubt we'll ever prove God by logic), regardless of one's beliefs, the Bible does say the "For by Grace are ye saved, THROUGH faith, and that NOT of yourselves. It is a gift of God" (Ephesians 2:8).

Note, then, that for those of us who believe we are saved, LOGIC is, in this instance, a failure. If God could be proved by logic, it would not be of faith, and, IPSO FACTO, then would not be the salvation we seek.

I don't try to prove God, and wonder why those who wish Him to be non-existent waste so much time and energy trying to disprove Him.
