Jul 19, 2019 at 13:26 comment added user4552 This seems conceptually muddled. GR doesn't have global frames of reference. See physics.stackexchange.com/questions/458854/… . And changing coordinates or changing the local frame of reference does not change a spacetime from flat to curved or curved to flat. A flat spacetime and a curved spacetimes are different spacetimes, and there is no natural way to associate points in one with points in the other.
