| Abstract |
I discuss the ontological assumptions and implications of General Relativity. I maintain
that General Relativity is a theory about gravitational fields, not about space-time. The latter is
a more basic ontological category, that emerges from physical relations among all existents. I
also argue that there are no physical singularities in space-time. Singular space-time models do
not belong to the ontology of the world: they are not things but concepts, i.e. defective solutions
of Einstein’s field equations. I briefly discuss the actual implication of the so-called singularity
theorems in General Relativity and some problems related to ontological assumptions of Quantum
Gravity.
