Stephen Hawkingâ€™s announcement is but the latest sign that the multiverse and, with it, philosophical naturalism is in trouble. Added to its technical difficulties, the theory fails to do what it sets out to do; namely, to explain how our universe turned out the way it did. Instead, it asserts that our world has to exist, because in an infinite number of universes, all configurations are possible and weâ€™re here, so that proves it! Such contrived reasoning leaves some researchers cold. A theory in which anything is possible is a theory that explains nothing.
Jim Manzi, a writer for NRO, classifies the Multiverse Theory in the same category as Intelligent Design. He views both as metaphysical frameworks, but neither as science. Personally, I think the hypocrisy of those subscribing to philosophical naturalism who are keeping the Multiverse Theory alive and well needs to be exposed. If something as non-empirical and non-observable as the Multiverse Theory is considered a legitimate scientific topic, then all philosophical musings should be allowed in the door.
It also seems to me that the Multiverse Theory never solves the basic worldview question of where we come from. Even if it turns out that the Multiverse Theory is right, it shifts the question of the beginning of our own universe to the beginning of zillions of universes. Now we have to answer, what caused them?
Like Regis, I think this theory should die of natural causes. Something tells me, however, that it won't anytime soon.
