(**) Every P-extendible P-spacetime has a P-inextendible P-extension. (**) Every P-extendible P-spacetime has a P-inextendible P-extension. Of course, spacetime properties may be considered physically reasonable in various senses. (1977), let us say that a spacetime (M,gab) is observationally indistinguishable from another spacetime (M′,g′ab) if, for every point p ∈ M, Under the standard definition of inextendibility, it seems that any observer in a chronological spacetime is not in a position to know that her Let (N,gab) be Misner spacetime.	./cache/work_k6f3i6okwrgznnh5vo6qitlxry.pdf	./txt/work_k6f3i6okwrgznnh5vo6qitlxry.txt
