As discussed in earlier posts, Alex Vilenkin's book, Many Worlds in One: The Search for Other Universes (New York: Hill and Wang, 2006), has a lot of relevance to the Kalam cosmological argument, although he doesn't discuss it directly. The argument can be formulated as follows:
- Everything that begins to exist has a cause.
- The universe began to exist.
- Therefore, the universe has a cause.
First, he presents a theorem that he developed with two other physicists that proves that any universe that is (on average) expanding must have a beginning. So he would agree with the second premise of the argument. Second, he presents his own theory for the beginning of the universe, which holds that the universe tunneled into existence out of nothing, without a cause. So he would disagree with the first premise of the argument. I've already discussed those issues and expressed my agreements and disagreements. But to wrap up my discussion of this book, I wanted to share my thoughts about what Vilenkin says about God.
