Structural Origin of Gravitational Waves: A Falsifiable Framework for Ringdown Deviations from General Relativity

This repository accompanies the preprint: Structural Origin of Gravitational Waves: A Falsifiable Framework for Ringdown Deviations from General Relativity The work presents an illustrative and falsifiable framework in which gravitational-wave ringdown signals are interpreted as manifestations of relaxation dynamics in an underlying structural field. Within this framework, structural perturbations may induce measurable deviations from General Relativity (GR) in quasinormal-mode (QNM) frequencies and damping times. The study introduces: An illustrative structural-field interpretation of gravitational-wave ringdown Analytical predictions for fractional frequency shifts (δf_struct) and damping-time shifts (δτ_struct) Parameter dependence on mass, spin, QNM mode, and structural coupling Structural propagation limits and observational consequences Detector-response modeling for current and future gravitational-wave observatories Illustrative confrontation with LIGO/Virgo/KAGRA observations Forecasts for future LISA observations A complete falsifiability framework A comprehensive validation strategy Multi-detector observational roadmap A long-term roadmap toward precision strong-field gravity tests This release contains: Preprint (PDF) Figure set (Fig.1–Fig.16) Demonstration Python script README documentation All figures, numerical examples, and simulations are explicitly illustrative and are intended to demonstrate the proposed framework. They are not derived from proprietary observational data and should not be interpreted as direct fits to LIGO, Virgo, KAGRA, or LISA observations.
