The stars in the spiral galaxies move in such a way that they increase their distance from the center of the black hole and make a mathematical series. We purpose a mathematical model for predicting the path of the stars in the spiral galaxies. The complex dimensional model is a novel mathematical series for illustrating the relationship between 4-dimensional movement in a 3-dimensional space. We show that the arms of spiral galaxies are the path of movement of stars when they try to keep their distance from the center of the galaxy in a 4-dimensional movement.
