Yes, that's because General Relativity is a classical theory that is not quantized, it has so far passed every experimental test posed to it with flying colors but we know it can't be entirely correct because when we ask it what happens when things become very small and very massive, such as in the center of Black Holes, it gives the absurd answer of infinity. Neither Quantum Mechanics or General Relativity works when things get massive and small, perhaps quantizing General Relativity will fix this or maybe there is some other way to do so. Nobody knows. > *I could be mistaken, but I see gravitons as being part of a distinct > theory of gravity, which might give the same results as GR,* Nobody has ever experimentally detected a graviton and it's extremely unlikely anybody ever will, so if they make the same predictions as standard General Relativity there would be no point in introducing the idea.
