Guest guest Posted January 1, 2004 Report Share Posted January 1, 2004 > <<Of course, the whole " perfect universe " thing is quite a quandary. Change just one of the physical laws of the universe, such as the number of macro-dimensions or the constant of gravity, and you've got yourself a universe with no life in it at all. Because of that astounding fact, I tend to be slightly theological in my views, although by no means a supporter of any sort of creationism.>> I've never had any problem accepting the Anthropic Principle. Basically, the universe is as it is (including such diverse things as distance from Earth to the Sun, and values of fundamental physical constants) because if it weren't like that, we wouldn't be here. It has to be finely adjusted to allow life, because otherwise there wouldn't be conscious beings around to wonder about it. <<My views on the " purpose " of life is that life is a entropic engine, designed to accelerate the speed of entropy.>> I don't exactly understand what you're saying here. Certainly, the second law of thermodynamics is used (in a rather inane way) as an objection to biological evolution. A living being grows by decreasing the entropy within itself. This in no way contradicts the second law, which applies only to *isolated systems*. An isolated system is one that exchanges neither matter nor energy with its surroundings. We take in low-entropy food and shit out high-entropy waste. On the scale of the biosphere, it certainly isn't an isolated system either: we're getting energy to the tune of 1300 W/sq. m at the top of the atmosphere from a certain nearby G2 main sequence star.
