Mass from Within: Estimating Planetary and Stellar Mass by Nucleon Count

This document presents the first foundational correction offered by USP Field Theory to classical physics: redefining how we understand and estimate mass. Instead of relying solely on gravitational force measurements, this approach shows how the mass of planets and stars can be estimated directly from nucleon count — the number of protons and neutrons — using average atomic mass values. For planets, silicate-based composition provides a working estimate. For stars, a hydrogen-helium average frames the stellar core's nucleonic structure. This bridges atomic structure with gravitational behavior, enabling a new understanding of Newton’s equations through spin tension geometry. In USP Field Theory, mass is not just weight — it is the field-locked geometry of spin. This is the first clear correction USP Field offers to classical physics: giving Newton’s equations a deeper atomic and structural meaning. The result is a direct link between matter's internal makeup and the forces it exerts in space — from Earth to the stars.
