Origins of attractive gravitational and boson forces

In the standard model (SM) and general relative theory (GR) based on the 4-D Minkowski space, the origin of the attractive gravitational force is not understood. The repulsive Coulomb force between two particles with the positive charges is explained by using the destructive interference of the electric waves emitted from two particles. Therefore, the destructive interference of the gravitational (graviton) waves emitted from two particles with the positive masses should make the repulsive gravitational force (F_r). But the attractive gravitational force (F_g) is observed. The masses lost during the destructive interference of the gravitational (graviton) waves are converted to the induced gamma rays making the new attractive force (F_a). The observed attractive gravitational force (F_g) should be originated by the equation of F_g = F_a – F_r > 0. This can explain the reason why the gravitational force (F_g) between the elementary particles is so weak when compared with the Coulomb forces. The destructive mass wave interference is possible between two massive bosons but not between two massive fermions because of Pauli exclusion principle. Therefore, there are the force carrying bosons but not the force carrying fermions. The boson forces are attractive because of the induced gamma rays due to the destructive interference of the mass oscillating waves. All elementary massive bosons, massive gravitons and massive neutrinos are considered as the mass oscillating wave forms with the high speed close to the light speed of c.
