What are the incompatibilities between GR and QM??

appart from the fact that GR is NOn-renormalizable (perturbatively :rolleyes: ) since there are almos infinite types of UV divergences \int_{0}^{\infty}dxx^{n} n=-1,0,1,2,3,4,...

What other incompatibilities are there?..if space weren't continuous but you could "triangularize" it somehow :frown: :frown: would these inconsistence disappear?? :shy:

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
