The significant part of the primordial matter of the universe remained without expansion or explosion which represents the center of the universe. According to Hubble’s law the velocity of distant galaxies is greater than the velocity of near galaxies. The objects of the solar system and stars moving around certain center with high orbital velocities near the center and gradually decrease far away from it. Then we can deduce that the galaxies are also moving around certain center (universe center) which is homogenous and isotropic. As all systems (Atom & Solar System & Galaxy), the universe center represents the most mass of universe which may be the dark matter. The orbital velocity of all celestial objects and galaxies can be determined by equation connecting the gravitational force, distance between systems, other velocities and their mass.
