Your logic is flawed. From God creating and sustaining and the universe going out of existence without his sustaining power you cannot conclude to the possibility of a universe " popping into existence " on its own. One has nothing to do with the other.If God stopped sustaining the universe, then it would become nothing? Think for a moment what you are claiming here. If a universe, without any aid, can suddenly (or gradually for that matter) vanish, that is, nothing at all would be left of it, theh why couldn’t the universe pop into existence from nothing without any aid?
The Thomistic idea of the universe needing a sustainer is based on a poor understanding by Aquinas (and by Aristotle) of basic physics. Aristotle and Aquinas thought that objects were constantly being ‘pushed’ or ‘attracted’. Nowadays it is understood that an object in motion will stay in motion forever, and that there can never again be a state of absolute nothingness.
The physics of Aristotle’s and Thomas’ day really has nothing to do with the basic truth of Thomistic philosophy. Thomas was well aware of causality other than motion or pushing and attracting. He knew of substantial change and final causality as well. In fact his philosophy contributed greately to the Doctrine of Transubstantiation in the Dogma of the Eucharist. Moderns tend to dismiss both him and Aristotle as some kind of ancient period pieces. Far from it. We need them more today than ever.
Now it was the opinion of Thomas, at least philosophically, that the universe would exist forever. I’m pretty sure about that. If I’m wrong someone will surely correct me. But I don’t know at the moment just what his reasoning was.
As far as the universe ceasing to exist without God’s sustaining power. That is absolutely true. The beings of the universe do exercise causality, no doubt about that. But they do not cause their act of existence. They cause change as secondary causes. It is only God who can make the change exist. No being whose existence is limited can exist without the sustaining power of God.
As far as the laws of nature are concerned. I see no contradiction between their validity and God’s sustaining power. It is obviously his will that these laws exist. I see no problem.
