I've often heard that general relativity and quantum mechanics are incompatible. From my understanding, the incompatiblity comes from GR uses curvatures of Space-time to explain gravity, and QM uses particles as force carriers, including the force of gravity. Do the two theories have to be mutually exclusive? Can forces be carried by particles, except for gravity, which is the distortion of space by the particles? Or gravity carried by gravitons that some how distorts space, or something in between?
