一个量子参考系的理论及其蕴含的引力理论

theory of quantum reference frame is considered in the paper, the induced Ricci flow of quantum spacetime and gravity theory are discussed by considering the second order moment of the quantum fluctuation of the reference frame. We also discuss the cosmic acceleration (cosmological constant problem), radial acceleration discrepancy of galaxies, inflation in the early universe, and the origin of spacetime entropy. Finally, we propose some possible predictions of the theory.
