Galactic Halo Sorting Shells and Minor-Body Dynamics in USP Field Theory ( msf:49010 )

This paper extends USP Field Theory’s resonance-based framework from planetary rings to galactic halos. In this view, a galactic halo functions as a long-lived Δf sorting shell surrounding a deep galactic resonance basin. Matter captured from intergalactic space—gas, stars, minor bodies, fragments, and resonance-inefficient mass—is gradually sorted by Δf compatibility rather than by violent gravitational collapse. Small moons, asteroids, comets, and debris are treated as “field gravel”: long-lived tracers that preserve atomic inventory, capture history, phase transitions, and impact memory. Their behavior is governed not only by size, but by the atomic and molecular mass they carry. Volatile-rich bodies undergo solid–liquid–gas transitions during stellar encounters, while weak internal gravity leads to widening, fragmentation, and mass shedding. These processes mirror planetary ring dissipation, but at galactic scale. The paper explicitly links halo dark mass to incomplete-reversal matter described in the unified cosmic lifecycle (msf:49000), providing a consistent origin for resonance-inefficient mass without invoking new particle species. Galaxies are described as long-term accretion reservoirs, collecting debris over billions of years while minor bodies record the history of capture and sorting. A simple retention proxy for volatile material in weakly bound bodies is expressed as: R_vol ≈ exp( − Φ_star / Φ_g ) where Φ_star represents stellar forcing (radiative and field-corridor disturbance) and Φ_g represents the object’s gravitational binding scale. This work unifies planetary rings, galactic halos, and minor-body populations into a single, scale-consistent Δf dissipation and sorting framework.
