In response to g (a while back, concerning entropy): If physicists discovered such a technique, omniscience of a sort(by arbitrarily altering and measuring the amount of information in a given region) would be possible, as would a form of omnipotence (we could arrange any concievable configuration of particles via Maxwell's demon). Hooking it up to a computer with some knowledge base of usually-accepted morals to this quantum entropy-decreasing construct, we would have omnibenevolence, also - hence, such a being would, indeed, be (an approximate) God by most standards. Except for having created the universe (could it possibly be used with some as-yet-unknown theory of quantum gravity to create some multiverses, or a loope in space-time back to the Big Bang?), such a being is about as close to a God as is logically possible.
