I always hear that these two things are incompatible but I never really hear why. The most I know is that QM assumes a quantized spacetime whereas GR assumes a dynamic one, but I don't really understand if this is correct (nor do I get what that really means). I don't see how GR would fail, for instance, if you just took the aggregate of quantum effects to the mass-scale such that certain aspects of the quantum world are negligible (much like how quantum effects are negligible when we talk about, say, adding velocities of classical objects).
What happens if you take QM's assumptions to the GR level and vice-versa? How does string theory aim to resolve QM and GR? Is it meant to give a new foundation of assumptions that work under both theories and yet still provide the same level of verifiability/testability/accuracy/etc as QM does in its own realm and as GR does in its own realm?
Any elucidation on the matter would be appreciated.
