Abstract

Novikov has developed a reference system built around times measured by radially moving geodesic clocks that is equivalent to Kruskal-Szekeres coordinates. From analysis of the construction of Novikov's reference system, I give arguments showing that the reference system is not maximally extended, as is commonly reported in the literature. On both Novikov and Kruskal-Szekeres spacetime diagrams, the left-hand side, corresponding to negative values of the spatial coordinate, should not be included when describing a physical spacetime. In turn, this means we have to rethink widely-accepted concepts such as black and white holes that arise from the usual picture of a maximally-extended Kruskal-Szekeres spacetime.
