Einstein's equivalence principle states that free-falling observers are in local inertial frame, so one can construct a local Minkowski frame everywhere.
So my question is whether the logic can be inversed, does every local Minkowski space represent free-falling? because in vierbein formalism, the vierbein may not be a coordinate frame.
