Over at Brandon Vogt’s fantastic website Strange Notions is this excellent, but brainy article be Fr Robert Spitzer on how contemporary physics points to a Creator.
We should begin by clarifying what science can really tell us about a beginning of the universe and supernatural causation. First, unlike philosophy and metaphysics, science cannot deductively prove a creation or God. This is because natural science deals with the physical universe and with the regularities which we call “laws of nature” that are obeyed by the phenomena within that universe. But God is not an object or phenomenon or regularity within the physical universe, so science cannot say anything about God. Moreover, science is an empirical and inductive discipline. As such, science cannot be certain that it has considered all possible data that would be relevant to a complete explanation of particular physical phenomena or the universe itself. It is always open to new data and discoveries which could alter its explanation of particular phenomena and the universe. This can be seen quite clearly in revisions made to the Big Bang model.
So what can science tell us? It can identify, aggregate, and synthesize evidence indicating that the finitude of past time in the universe as we currently know it to be and conceive it could be. Science can also identify the exceedingly high improbability of the random occurrence of conditions necessary to sustain life in the universe as we currently know it to be and conceive it could be.
Fr Spitzer goes on to explain the reasons we believe the universe had a beginning and if it had a beginning then what was before that was nothing. For something to come from nothing there had to be another force involved which theists say is God.
