Gravity Refinement in USP Field Theory: Neutron Stars, Galactic Black Holes, and Earth's Core

This three-part publication explores gravity from the perspective of USP Field Theory across vastly different cosmic scales. Part I: Neutron Stars — Models neutron stars as ultra-atoms, defining gravity through spin tension and compacted atomic cores. Part II: Galactic Black Holes — Reframes black hole gravity as field slope geometry, showing how stars and planets safely orbit without collapse. Part III: Earth’s Interior — Separates gravitational tension from pressure inside planetary bodies for more accurate modeling. Together, these papers refine gravity’s origin, demonstrate observational consistency, and pave the way for future USP-aligned simulations and instruments.
