Is an infinite universe supposed to be consistent with the Big Bang? Could an actual infinity come from a single "thing" or virtual magic box (singularity)? I'm not sure it's still strictly scientific to speak of such a relationship. Of course, the data will show what they show, but the question at issue is whether science will suffice to explain the cosmological data so that we understand where we came from. I suspect the science in question will be laced with philosophy and even with hidden theology (such as pantheism).
