But from what I understand, we know of no infinite quantities of anything actually existing in the universe. Augustine believed time existed in the physical universe only and God existed outside of it in eternity. My point was that whether someone believes the known universe to be eternal or whether they believe it to be finite/non-eternal; they are faced with the “problem” of eternity, a concept that I’m asserting goes beyond scientific theory because it’s difficult to avoid metaphysical implications with it. Either our universe had no beginning, which is inconceivable, or it came from something which had no beginning, which is inconceivable. If eternity is an accepted concept which nonetheless could never be scientifically proven, then it seems that we may already be accepting something which possesses transcendent qualities, such as God has, for example.
I was pointing out that we do know of theoretical infinite quantities. Pick any infinite set. The integers, the reals, any infinite line, etc.
Also, just because something goes beyond scientific theory in that it has metaphysical implications does not mean that it is “supernatural” in any traditional sense, as far as I know. Think of any important scientific theory, viz., general relativity, quantum theory, evolutinoary theory, etc. It is in this sense that I think an eternal universe is a scientific theory. As it happens, that theory at the moment has little credibility, unless you countenance multiverses, which there is no good practical reason for doing so at the moment. Also, the above theories are certainly not incomprehensible. We’d be in serious trouble if they were. It is in that sense that an eternal universe is also not incomprehensible.
I certainly don’t think an eternal universe is inconceivable as a scientific theory. For one thing, it
is a scientific theory. Again, not terribly likely at the moment, but a theory still, and no less conceivable for it. Likewise, I don’t think that a finite universe that was caused by something eternal, or inifinite, is inconceivable either.
Finally, all this speaks to your bit about scientific provability. In science, concepts aren’t “proven”, theories are. And they’re not proven the way theorems are proved in mathematics. They are sufficiently invested with empirical consequences and corresponding predictive value that scientists decide are good reasons for accepting, on the basis of scientific induction, their validity as good scientific theories. All that is a way of saying that, given what else we know, this theory is likely, and if we assume it, we expect to see things that, as it happens we do, in the way we expect to see them. This is why science is such a thrilling enterprise; because sometimes theories that are of immense predicitve value can clash. The best example at the moment is general relativity and quantum mechanics. It’s these types of tensions which drive scientists to silly hyperbole about a “theory of everything” and lead the general populace mystified as to how one can reconcile their religious beliefs with modern theories of everything that in principle cannot address religious belief. I’ve said too much.
God Bless
