All particles, objects and systems in the universe (Nuclei, Atoms, Molecules, Planets, Stars, Galaxies) are certain masses at certain distances with certain velocities bound by certain fundamental forces (Strong Nuclear Force & Electromagnetic Force & Gravitational Force). The main law or equation of all systems in the universe is controlled by these physical parameters. The four main physical parameters (force, mass, distance and velocity) for all systems in the universe are connected in one equation with two faces, one of them is expressed by velocity of light for small systems (Nuclei, Atoms, Molecules) and the other is expressed by rotational and orbital velocities of large bodies (Planets, Stars). With new form of main equation, it is found that the rotational and orbital velocity of Earth, Moon, Sun and Venus are agree with known calculated values and all calculations of all objects of the solar system are identical with known determined values. The following physical principle can be applied to all systems in the universe “Existing certain masses (nucleons, electrons, atoms, molecules, planets, stars) at certain distances is main condition of existing certain significant fundamental forces capable to form and bound certain systems with spin and orbital motions with certain velocities leading to the formation and construction of the universe”.
