Celestial Electrodynamics

An electrodynamic plenum framework for celestial mechanics is presented in which orbital dynamics, mass ratios and surface gravities follow without Newton’s constant . Space is modelled as a medium 𝐺of density , read through the magnetic bridge with : its ρ0=8.854×10−12 𝑘𝑔 𝑚−3ρ0=ε0𝐵∗2𝐵∗=1 𝑇inertia is the field momentum of a magnetised medium and its stiffness is . Mass is 𝐵∗2/μ0=ρ0𝑐2bipartite, an inert Mahatva and an interactive Gurutva whose coupling is 𝑀𝑞𝑚=𝑉ρ𝑢𝑛𝑐𝑀𝑒𝑓𝑓=𝑉ρ0reactive. The kinematic invariant replaces . The framework recovers , planetary Φ=𝑣2𝑟𝐺𝑀𝑔=Φ/𝑅2mass ratios to 1.2 percent (0.5 percent with the satellite-ranging ), the latitude variation of , Φ⊕𝑔satellite speeds and Kepler’s three laws. The local plenum index supplies 𝐾=1+2Φ/𝑟𝑐2()Mercury’s 43 arcsec per century and the gravitational redshift. A Quadratic PIP Resonance Law, , holds to 1 to 10 percent. Two failures are reported, the headwind eccentricity Φ𝑔𝑎𝑙/Φ⊙≈Φ⊙/Φ⊕()2law and the density-sorting law, and falsifiable tests are stated.
