The Endpoint Mechanism of Gravitational Redshift

This paper provides a critical revision of the gravitational redshift mechanism presented inA Complex History of Time. By abandoning the assumption of "path-dependent cumulativeeffects," we establish the theory of Quantum Endpoint Interaction. We demonstratethat photons exist within a "physical black box" during transit, where their fundamentalenergy remains strictly conserved between emission and reception. Gravitational redshiftis not a result of energy loss during propagation, but rather a measurement residualdetermined solely by the gravitational potential difference between the source and theobserver. Upon reaching Earth, photons undergo "instantaneous formatting" by the localphysical environment, causing the observed frequency shift to reflect the relative discrepancyin physical constants between the two nodes. By establishing algebraic equations basedon the redshift factor z, this theory achieves a closed-loop logic for directly decoding theabsolute Planck values and gravitational potentials of distant sources from macroscopicredshift observations
