Does the Universe Need God?

According to physics, that is. Prosblogion explores the question, as asked by a CalTech physicist, of whether the the physical explanations of the universe need a philosophical explanation to explain them. And if you’re following that so far, and if you like words like “metaphysical” and “ontological,” you are gonna love this:

Near the beginning of the article, Carroll quickly summarizes the possible responses to ‘first cause’-type cosmological arguments. It seems to me that he is on firm ground here: it is unclear whether there even is a first moment, and if there is then it is not clear that it even makes sense to ask what caused the state of the universe in that first moment, if we are looking for another cause in the series of causes. Besides (although Carroll does not make this point), classical philosophical theology does not conceive of God as one more cause in the series of causes. So the first cause argument isn’t really going anywhere. I myself think that insofar as the first cause argument is tempting, this is because it gets confused with the argument from contingency: people aren’t really asking what caused the first state of the universe, they are asking why was the state of the universe as it was, and it’s quite clear that, if there really is a first moment, then the answer to that question could not possibly be another ordinary physical cause: either it has no answer, or it has an answer of a very different sort.
