When the mass of one of the two bodies tends to zero, Weyl's definition of the gravitational force in an axially symmetric, static two-body solution can be given an invariant formulation in terms of a force 4-vector. The norm of this force is calculated for Bach's two-body solution, which is known to be in one-to-one correspondence with Schwarzschild's original solution when one of the two masses l, l' is made to vanish. In the limit when, say, l'→0, the norm of the force divided by l' and…

Utilizing various gauges of the radial coordinate, we give a General Relativistic (GR) description of static spherically symmetric spacetimes with a massive point source and vacuum outside this
On singularities, horizons, invariants, and the results of Antoci, Liebscher and Mihich (Gen Relativ Gravit 38, 15 (2006) and earlier)
Antoci et al. have argued that the horizons of the boost-rotation, Kerr and Schwarzschild solutions are singular, having shown that a certain invariantly defined acceleration scalar blows up at the
Classical gravitational spin–spin interaction
I obtain an exact, axially symmetric, stationary solution of Einstein's equations for two massless spinning particles. The term representing the spin–spin interaction agrees with recently published

We comment on the famous paper by Karl Schwarzschild from 1916, which is reprinted in the present issue.


The Gravitational equations and the problem of motion
Introduction. In this paper we investigate the fundamentally simple question of the extent to which the relativistic equations of gravitation determine the motion of ponderable bodies. Previous
Equations of Motion in General Relativity
This paper contains a new derivation of the equations of motion of bodies moving slowly in their (weak) gravitational field, up to terms of the order (v/c)2. In contrast to the method developed
Alternative space-time for the point mass
Schwarzschild's actual exterior solution (${g}_{\mathrm{S}}$) is resurrected, and together with the manifold ${M}_{0}={R}^{4}\ensuremath{-}{r=0}$ is shown to constitute a space-time possessing all
Black holes: the legacy of Hilbert's error
The historical postulates for the point mass are shown to be satisfied by an infinity of space–times, differing as to the limiting acceleration of a radially approaching test particle. Taking this ...
