Idea that time can have origin in entanglement is based on the preposition that “internal observer”, “external observer”, “coordinate time ” and “proper time ” are theoretical models of the world which have counterpart in physical universe. Bijective epistemology based on bijective function of set theory confirms these models have no counterpart in physical universe; they are pure theoretical inventions on which we cannot build a consistent scientific theory. Idea that time could have origin in entanglement has no enough theoretical and experimental basis to be taken seriously as an adequate model of physical world.
According to De Broglie's idea of analogy, the relation between quantum mechanics and classical mechanics is similar to that between wave optics and geometric optics, we have given the quantum equation of the gravitational field intensity Eg(r,t) for matter particles, since the gravitational field intensity Eg(r,t) relatives to the particle position distribution function ψ(r,t), the quantum equation convert into the Schrodinger equation. In addition, we have further studied the essence and origin of quantum theory, and obtained some new results.
