Can something come from nothing

[Neo-Scholastic]

The philosophical question goes back a very long way, doesn't it? I'm not sure where the OP is going with this, but as one Christian apologist to a presumably other one, IF your intention is to justify a creator god based on the idea of a temporal beginning, ex nihilo, THEN your efforts are seriously misguided. The question at hand is not the initiation of the physical universe; but rather it's sustenance. The background premise is that within the physical universe things that now exist could possibly cease to exist. The traditional phrase summarizing the idea is "creation is a constant coming into being." Without a Necessary Being (one that could not possibly cease to be), the argument goes, all of being could collapse into nothing. The complete demonstration is more subtle than that and was fully developed by Aquinas in Question 2 of the Summa Theological. You might want to check it out. Also you will find that the most common objection to the argument relies on the notion of "brute facts" so you should prepare yourself with an understanding of the Principle of Sufficient Reason.
