“…The Meissner effect is a quantum gravity effect in primordial field theory, derived from Equation (1). This topic is explored in reference [7], "The Ontology of Quantum Gravity", wherein the quantum wave function is interpreted to be the induced gravito-magnetic wave, a real physical field, whereas the quantum "wave function" of today's quantum gravity is unknown-no one is sure whether the nature of the wave function is epistemological (abstract) or ontological (physically real). As for the question, "any unification?…”
