New general relativity

Abstract

A gravitational theory is formulated on the Weitzenböck space-time, characterized by the vanishing curvature tensor (absolute parallelism) and by the torsion tensor formed of four parallel vector fields. This theory is called new general relativity, since Einstein in 1928 first gave its original form. New general relativity has three parameters $c_1$, $c_2$, and $\lambda$, besides the Einstein constant $\kappa$. In this paper we choose $c_1=0=c_2$, leaving open $\lambda$. We prove, among other things, that (i) a static, spherically symmetric gravitational field is given by the Schwarzschild metric, that (ii) in the weak-field approximation an antisymmetric field of zero mass and zero spin exists, besides gravitons, and that (iii) new general relativity agrees with all the experiments so far carried out.
