A proposed gravitodynamic theory

TL;DR

This paper introduces a gravitodynamic theory drawing parallels between gravity and electrodynamics, proposing new coordinate conditions, deriving equations of motion similar to Lorentz force, and explaining phenomena like Coriolis force and Sagnac effect.

Contribution

It presents a novel gravitodynamic framework based on Einstein's equivalence principle, with equations analogous to Maxwell's, and explains inertial forces in rotating systems.

Findings

Coriolis force arises from a magnetic-type gravitational field.

The Sagnac effect is explained within the gravitodynamic context.

Proposed coordinate conditions are supported by experimental facts.

Abstract

This paper proposes a gravitodynamic theory because there are similarities between gravitational theory and electrodynamics. Based on Einstein's principle of equivalence, two coordinate conditions are proposed into the four-dimensional line element and transformations. As a consequence,the equation of motion for gravitational force or inertial force has a form similar to the equation of Lorentz force on a charge in electrodynamics. The inertial forces in auniformly rotating system are calculated, which show that the Coriolis force is produced by a magnetic-type gravitational field. We have also calculated the Sagnac effect due to the rotation. These experimental facts strongly support our proposed coordinate conditions. In addition, the gravitodynamic field equations are briefly discussed. Since only four gravitational potentials (3 + 1 split) enter the metric tensor, the gravitodynamic field equations in ``3+1 split" form would be analogous to Maxwell's equations.
