This <a href="http://unisci.com/stories/20001/0204006.htm">article</a> describes a new theory that evolution of life requires the use of quantum mechanical multiverses. From a cursory reading, I don't buy it. The simpler explanation of coherence/dechoherence seems a tad easier to believe than parallel universes. What if we achieve complete artificial intelligence in a computer? Was it alive before, too? The paper posits that life is somehow different than nonlife at a quantum level. This should easily be disproved by the first computer artificial intelligence being. Or maybe it already has if you take alife into consideration.<p> <ul> In quantum mechanics, everything that can happen will happen. When an electron or proton is placed at a crossroads where it can travel to the right or to the left, it goes both ways. <p> In quantum systems, fundamental particles exist as ghostly "superpositions" where they can be in a billion different places at once or in a billion different states at once. <p> Today, one of the most popular interpretations, and one that has the backing of Nobel prize-winning physicists, is that there exists a multiverse in which everything that can happen really does happen -- but in parallel universes. Although our conscious self inhabits only one branch of the multiverse -- our own universe -- fundamental particles inhabit the entire multiverse. It is this property that allows them to occupy multiple places or states simultaneously: Each place or state is in a parallel universe. </ul>
