Dark matter was invented to explain the velocities of the stars at the edge of our galaxy and to make sure that Newton\'s gravity equation was still valid. Georges L. Le Sage suggested that gravity has a shielding property that explains how gravity works. Quirino Majorana did several experiments to prove that this property was valid. The author claims that the velocity of the stars in the galaxy indicates that there is a shielding effect and that it shows that we don\'t need dark matter and that Newton\'s universal gravitational constant is neither universal nor is it a constant.
