Possible Development of the Newton Gravitational Theory of Interactions.   An Alternative Approach to the Gravitational Theory
  This work is devoted to the discussion of an idea that gravitational interactions might be residual interactions of strong and electromagnetic interactions. Then, absence of the carriers of the gravitational interactions finds a natural explanation in the framework this idea. Besides, since masses (charges of the gravitational interactions) of particles are generated in strong, electromagnetic (and possibly, in other) interactions and if masses of the particles will be not generated in these interactions (i.e. $m \equiv 0$), then the gravitational interactions do not appear. That is also indirect confirmation of the considered idea. Connections between charge of the gravitational and other interactions are considered.
