Talk:Physics/Essays/Fedosin/Gravitational phase shift

The article states that "the phase shift is proportional to the integral of the gravitational vector potential D" which is a close approximation in the weak-field scenario. However, since this phase angle goes to π/2 at the event horizon of a black hole, the correct expression defining the phase shift for any gravitational field strength is given by sin(Δθ) = (m/ħ)∙∫D∙dℓ.
