REINSTATING SCHWARZSCHILD'S ORIGINAL
MANIFOLD AND ITS SINGULARITY
SALVATORE ANTOCI AND DIERCKEKKEHARD LIEBSCHER
Abstract. A review of results about this paradigmatic solution 1 to the eld
equations of Einstein's theory of general relativity is proposed. Firstly, an intro
ductory note of historical character explains the dierence between the original
Schwarzschild's solution and the \Schwarzschild solution" of all the books and the
research papers, that is due essentially to Hilbert, as well as the origin of the mis
nomer.
The viability of Hilbert's solution as a model for the spherically symmetric eld of
a \Massenpunkt" is then scrutinised. It is proved that Hilbert's solution contains
two main defects. In a fundamental paper written in 1950, J.L. Synge set two
postulates that the geodesic paths of a given metric must satisfy in order to comply
with our basic ideas on time, namely the postulate of order and the noncircuital
postulate. It is shown that neither Hilbert's solution, nor the equivalent metrics that
