  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.
