Classical and Quantum are recognized as the two realities of existence, but what is their
most significant commonality? It is what they both consider to be a real existent, space.
Since space makes existence possible by making place for what exists, it should be
paramount. Space, then, as a common paramount existent is ontologically fundamental
for both Classical and Quantum reality; fields existing in space are fundamental for the
quantum creation of particles.
As a possible first existent, space in the pre-universe with a potential for being actual can
become actual space in the current universe while releasing energy that created the
universe. Philosophers have asked why âis there something instead of nothingâ because
the existence of the universe seemed impossible since it could not start; the first existent
could not be. However, nothing does not exist; therefore, something must exist and that
something would be the first existent, immaterial space.
