Galaxy Rotation in the Space of Four Distance Dimensions

This study contains the solution of the dark matter mystery of spiral galaxies by using the space of four distance dimensions x, y, z, x', in which x' is the fourth distance dimension. The calculation of galaxy rotation has been presented in the space of four dimensions by using two dimensional section x, x' and three dimensional section x, y, x'. The four dimensional mass M which generates the main gravitation field of galaxy is located at the fourth dimension at the distance x' = X' and other dimensions are zero x = 0, y = 0, z = 0. The method to calculate the speed distribution curve of four dimensional mass V_M: the speed distribution curve V_M is calculated by using the equation in which the gravitational force is equal to the centrifugal force of rotation. The solution of this equation yields the speed distribution component V_M of the four dimensional mass M and the value of the mass M. In the publication [1] has been presented rotational speed distributions curves of the galaxy NGC 3198. The speed distribution curve of galactic halo in that publication corresponds to the speed distribution curve V_M of four dimensional mass M of this study. In order to find out how well this four dimensional model functions, the speed distribution curve V_M of four dimensional mass M has been calculated by using two
