Reinterpretation of the Cavendish Experiment in the Context of Expanding Earth Models: A Speculative Gravimagnetic Analogy

We explore a speculative reinterpretation of Cavendish-type experiments, proposing that the observed force between small masses may arise from a gravimagnetic-like effect tied to acceleration in Earth's gravitational field, rather than purely intrinsic mutual attraction. Drawing an analogy to electromagnetic forces and incorporating elements from expanding Earth hypotheses (e. g. , Maxlow 2001; Blinov kinetic gravity), we derive a force expression dependent on Earth's proposed mass growth rate 3. 18 10^-16 s^-1. Internal calculations are consistent within the model, but we acknowledge significant tensions with modern geodetic constraints (Earth radius change <0. 1 0. 8 mm/year from SLR, VLBI, GPS, GRACE) and plate tectonics evidence for subduction from seismic tomography. The absence of equivalent experiments in microgravity environments is noted as a potential avenue for future testing, though current evidence strongly supports standard Newtonian gravity at laboratory scales. This work is intended as a thought experiment in alternative gravitation theories.
