SP3 THEORY: FROM PLANETARY PRECESSION TO COLLIDING GALAXIES The Development of a Cross-Scale PACmesh Test Program

SP3 theory proposes that natural phenomena occur within a common three-dimensional, conditionable substrate termed PACmesh. Matter and energy do not act against an empty geometrical background in this formulation. Their presence and passage configure PACmesh; PACmesh can retain aspects of that configuration, reorganize, relax, and influence subsequent matter–energy behavior.

The scientific usefulness of this proposal depends not upon the breadth of phenomena that can be described after observation, but upon whether a small common rule set can generate quantitative predictions that survive transfer between scales and systems.

This paper records the development of that test program immediately before a new analysis of the interacting galaxy system NGC 4676, The Mice. The progression has been: (1) formulation of PACmesh as the substrate of SP3; (2) development of a simple cross-scale behavioral rulebook centered on conditioning, retained history, relaxation, coherence joining, stiffness and directional response; (3) construction of Solar-System precession as a quantitative calibration problem, particularly around Mercury perihelion; (4) identification in NGC 628 of a candidate short-timescale history-associated signal concentrated approximately within 2–10 Myr and maximal in the tested analysis near 5 Myr; and (5) translation of these ideas into a prospective galaxy-collision reconstruction test.

The resulting MICE-4.1 Directional Passage–Response Reconstruction is preregistered conceptually here before its principal measurements are examined. H I, Hα, stellar morphology and velocity information will be registered in a common spatial framework. Prior matter trajectories will be reconstructed independently of the proposed PACmesh response. Spatial displacement between reconstructed passage structures and subsequent gas/star-formation structures will be converted to observational response times where possible.

The principal cross-scale SP3 prediction is frozen before analysis: if the NGC 628 timescale represents a transferable PACmesh passage–response phenomenon, measurable offsets in appropriate regions of NGC 4676 should preferentially map into approximately 2–10 Myr, with ~5 Myr constituting an a priori maximum-interest timescale rather than an adjustable fit parameter.

Star formation following a galactic encounter is explicitly not treated as distinctive evidence for PACmesh. Conventional gravitational, tidal, hydrodynamic, shock, compression and star-formation mechanisms provide the necessary comparison. The proposed discriminator is instead history-dependent spatial and temporal ordering that cannot be reduced to instantaneous local conditions alone.

This paper therefore marks a methodological boundary: the proposed rule and prediction are recorded before the new galactic test is opened. Appendix provides methodology.
