How the material universe could be contingent and needs a sustainer if the Heisenberg uncertainty principle is correct? According to this principle, the position and momentum of a particle cannot be known simultaneously and exactly.
First of all the Heisenberg uncertianty principle isn’t a principle in the modern version of quantum mechanics, but a mathematical theorem. Besides, the point is not that “the position and momentum of a particle cannot be known simultaneously and exactly” but that quantum particles do not have simultaneoulsy a definite value of position and momentum, a result supported by many experiments about entanglement.
The point is that what we call “quantum particles” are indeed not particles, but “entities” which can be defined only through abstract mathematical structures (and we call these structures “quantum particles”). This was clearly stated also by Werner Heisenberg:
“The smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language”
“The atoms or elementary particles themselves are not real; they form a world of potentialities or possibilities rather than one of things or facts.”
“The ontology of materialism rested upon the illusion that the kind of existence, the direct “actuality” of the world around us, can be extrapolated into the atomic range. This extrapolation is impossible, however.”
As a physicist, I think that a rational analysis of our scientific knowledges provides strong and convincent arguments supporting the existence of a personal intelligent Creator. In fact, all what science shows about the universe is that it manifests itself to us as a realization of some specific abstract mathematical models (what we call “the laws of physics”). On the other hand, mathematical models are only constructions of the rational thought and a mathematical model can exist only as a thought in a thinking mind conceiving it; therefore the existence of this mathematically structured universe implies the existence of an intelligent God, conceiving if as a mathematrical model. In other words, the universe can be only the manifestation of a mathematical theory existing in the mind of an intelligent and conscious God, i.e. a personal God.
