Scientific paper

This letter presents expressions for: Newton's law of universal gravitation, Milgrom's expression of Modified Newtonian Dynamics [MOND] for the velocity of stars at the out-skirts of spiral-galaxies, and some new relations between mass and radius of: globular-clusters, spiral-galaxies, and the galactic-clusters without any need for the big G. These expressions suggest that the strength of gravity and velocities of stars at the out-skirts of spiral-galaxies would be different if the total-mass and radius of the universe were different.
