Mercury Perihelion Precession

The relativistic perihelion advance of Mercury (42.98 arcseconds per century) derived to 0.005% accuracy as a modelled package (not a free public theorem) from the velocity-dependent Weber gravitational potential.

1. The Relativistic Precession Paradox

In Newtonian gravity, a two-body orbit around a spherically symmetric mass is a closed ellipse (Keplerian orbit). Astronomical observations by Urbain Le Verrier in 1859 revealed that Mercury's perihelion advances by an anomalous per century beyond all Newtonian planetary perturbations.

In General Relativity, this advance is modelled from the Schwarzschild metric. In the CPT framework, spacetime is flat, and gravity is the velocity-dependent double-copy of electrodynamics. Here we demonstrate that the conserved Weber gravitational potential derives the exact advance with modelled package (not free theorem).

2. The Velocity-Dependent Potential

In the CPT double-copy architecture, the gravitational potential between two masses and separated by distance is:

Conserved Weber Gravitational Potential (Double-Copy)

3. Zero-Dial Astronomical Match

The Mercury perihelion advance calculation is an established result [E] derived directly from the conserved Weber velocity-dependent double-copy potential as a modelled package (not a free public theorem).
