Phys. Rev. D 79, 124041 (2009) [3 pages]Even the Minkowski space is holedReceived 5 May 2009; published 26 June 2009 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. © 2009 The American Physical Society URL:
