MHS!physics Friday release: Inertial Reference-Frame Interaction Hypothesis (IRFIH)
Nested inertial frames—Earth, Sun, Galaxy—can exchange angular momentum. IRFIH derives a coupling term matching mm/s fly-by Δv still unexplained by GR.
Plain Lagrangian mechanics; no new constants. Predicts measurable effects on upcoming GEO-transfer perigees.
