Unification of the fundamental forces–gravity, electromagnetism, and the strong and weak nuclear forces, possibly at the quantum level–has been the highest quest of modern physics but has not been found in a set of field equations or "theory of everything." These diverse forces of widely varying strengths using different constants and units are not reducible to a single phenomenon at the current low temperature state of the universe. An evolutionary, big bang origin of the universe is not advocated. Nevertheless, radiation temperature is shown to be a parameter of unification, and although introduction of this concept does not end in a comprehensive unified theory, it points to unification in the Creator, the God of the universe, in His singularity conditions, beyond natural law and quantification.
