The Fabric Model: A Unified Description of Terahertz Anomalies in Biomolecules and a Proposed Experimental Test (v2.1)

The Fabric Model: A Unified Description of Terahertz Anomalies in Biomolecules and a Proposed Experimental Test. Version 2.1 — Major revision. This manifesto proposes a decisive two-chamber THz resonance experiment to test the Fabric hypothesis, a unified framework where mass arises as a frequency discrepancy in a spectrally reactive spacetime medium. Four empirical anchors constrain the universal stability parameter D = 0.489. A joint prediction links THz protein resonance to a gravitational-wave peak in the nHz band. The previously claimed PKIKP seismic anchor has been withdrawn after independent verification (July 2026). All predictions are falsifiable. The outcome is binary. Changes in v2.1:- Added: Four empirical anchors with scale diagram; D as universal stability parameter; Limitations section; two-class mass structure; joint PTA+THz prediction; spatial variation of hadron masses; BSA control in experiment; Appendices A/B/C completed.- Withdrawn: PKIKP seismic anchor after failed ISC verification.- Expanded: Table of Predictions from 6 to 10 entries.
