Cosmological Constant Not Fine Tuned For Life 536
eldavojohn writes "A common argument one might encounter in intelligent design or the arduous process of resolving science with religion is that the physical constants of our world are fine tuned for life by some creator or designer. A University of Alberta theoretical physicist claims quite the opposite when it comes to the cosmological constant. His paper says that our ever expanding universe has a positive cosmological constant and he explains that the optimum cosmological constant for maximizing the chances of life in the universe would be slightly negative: 'any positive value of the constant would tend to decrease the fraction of matter that forms into galaxies, reducing the amount available for life. Therefore the measured value of the cosmological constant, which is positive, is evidence against the idea that the constants have been fine-tuned for life.'"

Doesn't the Anthropic Principle [wikipedia.org] adequately deal with this issue in any case?
From the paper I linked in the summary:
Perhaps a more common view among physicists today is the idea that there is a multiverse with a wide range of values for the constants of physics, and by the selection principle of observership (the weak anthropic principle), we find ourselves in the part of the multiverse where life is possible and/or relatively common (at least compared to other parts of the multiverse) [7]. However, there is still considerable controversy over whether such a multiverse that would be necessary for this explanation really exists.
And then later the author says (calling this the 'third view'):
The third view, of observer selection within a multiverse, is hard to prove or disprove directly, since it appears very difficult to obtain direct information about other possible parts of a multiverse. However, if a simple theory were developed that gives good statistical explanations for what we do observe and that also predicts a multiverse that we cannot directly observe, such a theory could become highly convincing (analogous to the prediction by general relativity of very high curvature in black-hole interior regions that cannot be directly observed).
I believe the intent of this paper was to directly address the claims instead of using the weak anthropic principle. More importantly, his argument is falsifiable (that coveted trait in the scientific process) whereby the other three views are not at this time. As other posters have pointed out [slashdot.org] we can now attempt to reason out this theory further.

Another idea is that there is some deeper law of nature, which we have yet to discover, that sets the constants as they are. Yet another is that the constants can take more or less any value in an infinite multitude of universes. In ours, they are just right, which is why we have been able to evolve to observe them.

I said nothing about proof. Proof is a pretty big word. :)
Furthermore, what is not tuned for us? The "tuning" seems to refer to the likelihood of other worlds (in other galaxies) evolving life. How is the universe "sub-optimal" ... sub-optimal for what? Are you under the understanding that creationists believe God created the entire universe for creatures on earth to live in? As far as I am aware in the Bible, it specifically states that man is to "rule" over the earth. He makes no mention of Mars.

None of these arguments have any bearing on the subject, because in the end you are speculating on what said creator "would have done". Would constants be biased in favor of more favorable, or less favorable conditions? Noone knows, and those arguing against a creator will make the argument that the results of their studies disprove said creator.
At the end of the day, the statement on creation tends to be "things are as they are because they were intentionally made that way." Showing that X constant make

oh, yes, the 'frist psot', also not fine tuned for life. Well, not fine tuned for intelligent life.

Venus is well outside the habitable zone, for obvious reasons. It's not near habitability. If you moved the Earth inward from 1 AU to 0.95 AU, the stratosphere would moisten and you'd gradually lose all the planet's water to photodissociation followed by hydrogen escape. This is arguably the inner edge of the habitable zone. If you moved the Earth in to 0.85 AU, you'd boil the oceans and produce a runaway greenhouse. Venus is at about 0.72 AU.
See chapter 6 of this book [princeton.edu], partly based on this paper [psu.edu] (PDF)

There's something wrong with an estimate that puts Venus (at 0.723 AU) inside the habitable zone, since it has a runaway greenhouse. That's a pretty good working definition of "uninhabitable". The 0.725 bound comes from an early paper with a simplified model. The later papers listed on Wikipedia (Hart et al., Fogg, Kasting et al.) all put the inner edge at around 0.95 AU, which we're even closer to. But there is some debate as to what would be "uninhabitable". According to Kasting, at 0.95 AU you would

Just look at any government. Intelligent design surely would not allow for such insanity.
Better: Look at any very large religious / church bureaucracy, ID surely would not allow for such insanity.

Intelligent Design is pseudo science, an attempt to use science, logic, and reason to suggest the existence of God.
How does intelligent design use science? I cites the results of other science (mostly to attack them), but as far as I've seen never "uses" science. Rather, intelligent design presupposes an answer then tries to attack scientific results they don't like without using the scientific method to demonstrate anything, but while misleadingly calling their assertions "science".
