This paper constructs a model of the universe based on the flow of dark matter fluids in space-time in the universe, the model analyzes the hydrodynamic equations of dark matter fluids and the composition of dark matter fluids. It is also pointed out that the flow of dark matter fluids can be divided into two states: laminar flow and turbulent flow. The laminar flow of dark matter fluids is the main component of dark matter in the universe at present. The turbulence of dark matter fluids forms two symmetrical space-time. One is observable real spacetime, and the other is unobservable virtual spacetime. Virtual Spacetime is also part of dark matter. In dark matter turbulence, vortex structures of fluids can be formed. When vortexes of electromagnetic fields are formed, electrons, protons and magnetic monopoles are produced. Vortexes of electromagnetic fields will be able to automatically satisfy the conditions for Dirac's quantization of charge. Finally, this paper gives a hierarchy of matter in the universe.
