There is no infinity in the universe, not anywhere, and not in any levels. Space is not infinite, nor is matter, time or enegy. The criteria for infinity is 'no changes', and that none of its parts can be finite. You can't add $5 to an infinite amount of $.
Infinity is Sci-Fi. It is resorted to as a deflection from failed theories and premises, used to justify the unjustifiable. One must thus examine all theories and see if they work in a finite universe; if not - its should be discarded from the science sector.
