广义相对论的本体论
The ontology of General Relativity
摘要：
我讨论了本体论假设和广义相对论的含义。我坚持认为，广义相对论是关于引力场的理论，而不是关于时空的理论。后者是一个更基本的本体论范畴，它产生于所有不可知者之间的物理关系。我还论证了时空中不存在物理奇点。奇异时空模型不属于世界的本体论：它们不是事物，而是概念，即爱因斯坦场方程的缺陷解。简要讨论了广义相对论中所谓奇点定理的实际含义以及与量子引力的本体论假设有关的一些问题。
英文摘要：
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.
