Why do particles have the masses they do? This paper tackles a particularly difficult part of that question: neutrinos, exceptionally light particles whose three mass states have an uneven spacing. The aim is to discover whether that pattern can emerge from VERSF’s underlying Fold geometry. “Source-fixed” describes the ambition: the physical source should determine the calculation’s inputs, allowing the theory to make a prediction that experiments can test.
The paper develops a proposed connection between Fold geometry, the history of physical interactions, and the resulting neutrino masses. Under a particular prescription for translating that geometry into the neutrino calculation, it reports a value of approximately 0.0282 for the ratio describing the spacing of the squared masses. The experimental benchmark used in the paper is approximately 0.0298, placing the candidate about 5.3% below it. Earlier constructions give substantially poorer results, helping identify which proposed mechanisms remain viable.
This advances VERSF’s wider programme to derive the Standard Model and account for neutrino masses by making the connection between its foundational ideas and a measurable quantity more explicit. It develops the mathematical steps needed to turn a geometric source into a mass pattern, examines which effects can change that pattern, and identifies where additional physical justification is required. Documenting unsuccessful constructions also helps prevent the programme from repeatedly pursuing routes that have already failed.
The word “attempt” remains essential. The result is a reported conditional candidate: the exact generation inputs still need to be recovered, the complete calculation independently reproduced, and the proposed treatment of the Fold orientations derived from the theory. The paper therefore provides a more concrete route towards a neutrino mass prediction, together with clear tests that can confirm, revise or reject it.
