Reinterpreting Seismic Waves as Massive Gravitational Waves: A Theoretical Framework

We propose a radical reinterpretation of seismic wave phenomena in the context of massive gravity theories. Building upon the framework of de Rham–Gabadadze–Tolley (dRGT) and bimetric models, we hypothesize that seismic P-waves and S-waves correspond to longitudinal and transverse modes of massive gravitational waves trapped within Earth’s gravitational potential. In this framework, Earth acts as a low-frequency conductor of gravitational waves, with graviton mass introducing dispersion and mode variety beyond general relativity. We further correlate observed gravitational anomalies and seismic hotspots to the presence of exotic compact objects, such as primordial black holes and cosmic string remnants, embedded within the Earth’s interior. The coupling between cosmic-scale defects and geophysical observables is explored via geoid anomalies, free Earth oscillations, and inverse gravity modeling. We outline testable predictions, including correlations between LIGO/Virgo data and seismic activity, as well as tidal modulation of graviton modes. Our approach integrates quantum gravity conjectures with planetary geophysics, providing a novel multi-scale perspective on Earth structure and dynamics.
