 Several replies to this argument can be made. First, questions have been raised about the adequacy of the theory of inflation to explain the expansion of the universe. One problem is predictability, for on this view anything that can happen will happen, an infinite number of times (Steinhardt 2011: 42). Further, the argument presupposes that the General Theory of Relativity applies to the beginning of the universe, but some doubt that this is so, given that it cannot adequately account for the quantum gravity involved.
