Nested Space-Phase Stiffness, Memory, and Orbital Precession

SP3 theory proposes that matter collectively conditions a nested space-phase medium and thatinteractions among differently conditioned nests transmit momentum through distributedstresses. This exploratory paper develops a back-of-the-envelope constitutive modeldistinguishing smooth conditioning, propagating disturbances, hysteretic reconfiguration, andnonlinear encounters. A candidate nonlinear stiffness law and memory evolution equation areexamined; a simplified wave equation yields a propagation-speed constraint; and an illustrativecentral-force correction produces apsidal precession. None of these calculations establishes aphysical space medium or derives Mercury’s precession from magnetic measurements. Thepaper instead identifies the missing cross-scale derivation and a falsifiable, non-doublecounting comparison with existing orbital dynamics.
