          Abstract

          It is discussed that the formation of the spiral galaxies is drived by the cosmos background rotation, not a result of an isolated evolution proposed by the density wave theory. To analyze the motions of the galaxies, a simple double particle galaxy model is considered in this paper and the Coriolis force formed by the rotational background is introduced. The numerical analysis shows that not only the trajectory of the particle is the spiral shape, but also the relationship between the velocity and the radius reveals both the existence of the spiral arm and the evolution of the number of the spiral arms. In addition, the results of the three-dimensional simulation also give the warped structure of the spiral galaxes, and shows that the disc surface of the warped galaxy, Like a spinning coins on the table, exists a whole overturning movement. Through the analysis, it can be concluded that the background environment of the spiral galaxies have a large-scale rotation, and the formation and evolution of the cosmic-hurricane-like spiral galaxies is drived by this background rotation.
