Einstein’s hole argument and Schwarzschild singularities

Abstract

According to the Einstein hole argument, vacuum metric solutions are equivalent only if they correspond to the same energy–momentum tensor in the source region. In this paper it is shown that singular coordinates that are used to show Schwarzschild geodesics completeness, introduce the fictive delta-like sources at the horizon. Then, metric tensors obtained by such singular transformations, cannot be considered as solutions of the same Einstein equations with the central source.
