Key Points

  • To formulate and evaluate a gravitational theory on Weitzenböck space-time using absolute parallelism and torsion rather than curvature.
  • Constructed a gravitational framework on Weitzenböck space-time based on four parallel vector fields with vanishing curvature and defined torsion tensors.
  • Constrained the theoretical parameter space by setting parameters c1 = 0 and c2 = 0 while leaving parameter λ open.
  • Derived analytical solutions for static spherically symmetric fields and performed weak-field approximations.
  • Demonstrated that static, spherically symmetric gravitational fields precisely recover the Schwarzschild metric.
  • Identified that weak-field approximations yield an antisymmetric field with zero mass and zero spin in addition to standard gravitons.
  • Established that the constrained formulation remains in complete agreement with all existing experimental tests of gravity.

Abstract

A gravitational theory is formulated on the Weitzenb\"ock 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 c₁, c₂, and, besides the Einstein constant. In this paper we choose c₁=0=c₂, leaving open. 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.
