The Study of the Origin of the Universe

The goal of this article is to propose a new cosmological model of origin beyond which the Universe that we live in is a matter world. We can called it as the general universe. In the general universe our universe undergoes like a black hole which is accrescent. From the concept of the general universe, and the accretion of the universe, it can be proved that this expansion of the universe is a result of the universal gravitational potential energy and the acceleration of the Universe is always in existence forever,not by the so-called repulsing energy or dark energy, and may answer the beginning of the universe.
