1. Inverse Square Law

   Linked via "spatial metric"

   $$\text{F}g = \text{G} \frac{m1 m_2}{r^2}$$
   The consequence of this specific inverse-square dependence is profound: unperturbed two-body systems generate closed, predictable orbits that are stable conic sections (ellipses, parabolas, or hyperbolas). Deviations from this exact dependence—such as observed in the perihelion advance of Mercury (planet)—are often attributed to [relativistic corrections](/entries/relativistic-corre…
