Abstract
To cure the lack of predictive power of general relativity, Geroch proposed to complete the theory with an additional postulate that only “hole-free” spacetimes are permitted. This postulate (or, rather, that obtained from it by some disambiguating) seems physically well-founded and at the same time appropriately restrictive. I show, however, that it is too strong—it prohibits even the Minkowski space.
