Almost all quantum theories of gravity, which attempt to explain gravity using quantum mechanics, predict that the equivalence principle should be violated at the atomic level, and that the free-fall acceleration under such circumstances should depend on a quantum particle's properties, such as its spin.

General relativity is established on two principles (Einstein et al 1923, Einstein 1954), namely: 1) Einstein's equivalence principle, which requires the Einstein-Minkowski condition that a free falling point-like particle in a gravitational field is along a geodesic and results in a co-moving local Minkowski space; and 2) the principle of general relativity, that is "The law of physics must be of such a nature that they apply to systems of reference in any kind of motion.
