The only difference between an infinite singularity and an infinite number of (necessarily relatively existing) parts is that the former precludes conceptualization while the latter demands it. This being the case, the proof that there is no infinite singularity but rather an infinity of parts insofar as the ontological reality of the universe is concerned is that man conceptualizes. And the proof of this is the fact that I have written this post, and that you have read it.
The fact that there is only a relatively existing infinity of parts and not an infinite singularity also serves to prove that conceptualization cannot be existentially/ontologically/metaphysically/physically divorced from reality. Relativity and conceptualization must be corollaries. In other words, man’s ability to declare what things are is fully integrated into the object reality of the universe. Without man’s naming of that which he says is, by his ability to conceptualize the relative interaction of the infinity of parts he observes, there can be nothing at all.
