**Abstract.**
Gravity
is the curvature of spacetime, the structural property of static
gravitational field, a geometric field, in curved coordinates,
according the functions g_{uv},
that express geometric relations between material events. Course,
general relativity is a relational theory, however, gravity, a
thinking category, has symetric physical effects with matter. We use,
analitic and critic method of reread the general relativity, since
the perspective of the history of the science and the philosophy of
the science. Our goal is driver the debate on gravity, to the arena
of the quantum physics, but without the ballast of the general
relativity. We find that through of relativist aether was attempted
transform spacetime in a substantia without succes, the consequence
was return to problematic geometric field. The philosophy of the
science intervenes, and according the best philosophical theory of
substantivalism, spacetime is a inmaterial, geometric substantia.
Then, the metaphysics arrives to a full solution in the
super-substantivalism theory, that affirms: matter arises from
geometric spacetime. Thus, it explains consistently the symetric
physical effects between spacetime and matter. Surely, this solution
is a medieval speculation. Our conclusion is that since general
relativity do not defined physically spacetime leads necessarily to
philosophical definitions of relationism and substantivalism on
spacetime that are unacceptable physically. Therefore, gravity is
not the curvature of spacetime.
