The theoretical contradiction between General Relativity and Quantum Gravity about gravity was ended, since spacetime is not structural
property of the gravitational fi eld like Einstein said. Exactly spacetime is the structural geometric property of the matter and energy that it gives their geometric dimensions. Thus, spacetime is not continent of the matter (Substantialism), since it is contained. Neither is the category of the relations between material bodies or between their events (Relationalism) since is not relational property; spacetime is structural property. The particle-wave, of matter and eld, has intrinsically three spatial dimensions and one temporal dimension. The spacetime is intrinsically the structural quality of particle-wave. The spacetime is the geometric dimensions of the particle-wave itself and for others. Therefore, the matter and its movements are containing itself. Now only Quantum Gravity is possible.
