How compatible would you call the theories of gravity being a force vs spacetime curvatures vs quantum theory?
The force that results from gravity is equivalent to the force that results as a consequence of spacetime curvature. That is the main result of Einstein’s theory of general relativity, in which the force of gravity was unified with spacetime geometry. General relativity, of course, is not to be confused with special relativity, which is formulated with no spacetime curvature (special relativity, if you remember, states that nothing can go faster than light). Now unifying the general relativity picture of gravity with quantum theory is a problem. The leading quantum theories for describing fundamental particles and forces (forces are also called interactions, and are also particles themselves in this framework), are called quantum field theories. These theories have two major elements that distinguish them from basic quantum mechanics. They are compatible with special relativity, and they incorporate particle creation and annihilation. Attempts at formulating a quantum field theory for
