 One question that arises with Rundle’s view is whether there could have been more or less matter/energy than there is. That is, if there is \(n\) amount of matter/energy in the world, could there be a possible world with \(+n\) or \(-n\) amounts of matter/energy? We do not know how much matter/energy existed in the first \(10^{-35}\) seconds of the universe. Even if the universe currently operates according to the principle of the Conservation of Matter and Energy, Rundle’s thesis depends on the contention that during the very early phase of rapid expansion, a period of time we know little about, this principle held. A second significant problem concerns what follows from the existence of necessary beings. If the matter/energy nexus constitutes the necessary being, what causally follows from that nexus is itself necessary, and contingency, even in the composing relations within the universe, would disappear. Everything in the universe would be necessary, which is a disquieting position. Third, O’Connor (2004) argues that since the necessary being provides the ultimate explanation, there is no explanation of the differentiation of the kinds of matter or of contingencies that matter/energy causally undergo, for example, in terms of space-time location. We will return to the question of the contingency of the universe below.
