Modern physics has brought us to a realization of the oneness of our universe, from which we may better grasp the Oneness of its Creator:

It was once thought that each of the forces of nature is an isolated force, and that matter is a composite of many varied elements. But the more modern science investigated, the more it became apparent that this multitude of distinct elements and forces lies only at the surface, an artifact of the synthesis of parts, their contraction and expansion, etc. The number of basic elements was further reduced until it was realized that the world’s existence essentially consists of a union of two elements, quantity and quality (matter and energy).

True, simple oneness, void of duality, is found only in the divine. From G‑d’s perspective, there is only oneness. But if we will look at a created being as an entity in and of itself, it is a union of two elements—quantity and quality.
