Ill put it this way one of the reasons GR was so quickly accepted by the scientific community was because it explained Newtonian mechanics. When a new theory replaces an older theory it usually does so by explaining the limitations of the older theory. It is extremely rare to find an instance where a newer scientific theory completely refuted the older theory, as opposed to merely explaining it to a deeper more precise level.I think the difference becomes very very small indeed. I see no reason however why we should therefore require a new theory to explain the success of the old one ?
GR is gravity and, due to the sheer relative weakness of gravity compared with the other three forces, it rarely ever features in QM calculations. Gravity, whether Newtonian or Einsteinian, has never meshed well with QM (discrete distances, for example, make little sense in either framework despite being integral to QM).I had thought that classical physics follow from quantum mechanics when we deal with larger objects (with a delta similar to the one between newton and einstein) while relativity (indeed at least the GR) seems to almost contradict certain fundamental assertions of QM.
To give an easy to see illustration of one of the problems consider that the discrete-based mathematics of QM cannot simply be combined with the continuous-based mathematics of GR.
Another example can be seen in the behaviour of elementary particles (such as the electron). Some scenarios the particle behaves like a point mass (making it predictable under GR) while in others it behaves like a wave (making it predictable under QM).
Simply put - a ******* nightmare.
