Volume IV

This volume is part of the series EQT Reinterpretations of Observational Data. It examines transient gravity anomalies recorded by GRACE-type satellite missions from the perspective of Energy Quantum Theory, while treating classical geophysics as the effective benchmark for deep-Earth mass redistribution and gravity-gradient interpretation.

The book does not seek to replace established geophysical explanations. In particular, the reported 2006-2008 East Atlantic dipole gravity-gradient anomaly, peaking in January 2007 and possibly originating near the core-mantle boundary, is treated as a geophysical event whose conventional interpretation in terms of transient deep-Earth mass redistribution remains valid at the mechanism level. The question pursued here is narrower: can single-device gravity-gradient data be reorganized within the EQT framework as a low-frequency gravitational density perturbation, and can such a reinterpretation generate diagnostic structure and falsifiable predictions beyond restating the known event?

The central argument proceeds in a disciplined sequence. First, the anomaly is reformulated as the evolution of a perturbation in the low-frequency gravitational component of the energy-quantum density field. Second, the recorded gravity-gradient signal is interpreted as a co-evolutionary transient formed by the interaction between the GRACE satellite system and the deep-Earth source. Third, the book develops single-device detectability criteria: frequency matching, amplitude threshold, three-state decomposition, and detection-matrix positioning. These criteria clarify what GRACE can record, what remains below its response threshold, and when a deep-Earth disturbance becomes an empirically meaningful gravity-gradient signal.

A distinctive feature of this volume is its treatment of the 2007 East Atlantic event as a single-frequency closed process. Although geomagnetic jerks are often described in electromagnetic terms, their dynamical origin lies in large-scale fluid motion in the outer core, with characteristic timescales in the low-frequency gravitational regime. The book therefore reads the anomaly as a low-frequency source, low-frequency field response, and low-frequency gravity-gradient output within the same gravitational band, rather than as a cross-frequency electromagnetic-to-gravitational conversion.

Within this framework, EQT offers a structured reinterpretation of the anomaly's lifecycle. The initial appearance of the signal is read as a threshold-crossing event; the peak corresponds to nonlinear aggregation; and the subsequent disappearance reflects diffusive dissipation back toward the gravitational background. The observed dipole structure is analyzed as a mixed readout of free-state, bound-state, and condensed-state contributions within the gravitational density perturbation.

The methodological commitment of the book is falsifiability. Each reinterpretive step must be connected to possible failure conditions. If the signal cannot be reproduced under controlled processing choices, the observational basis fails. If the inferred aggregation--dissipation rhythm cannot be separated from filtering artifacts, the dynamical interpretation fails. If the three-state decomposition does not yield stable residual structure, the state interpretation fails. If predicted analogues are not observed in GRACE-FO, GRACE-C, or comparable single-device gravity missions, the proposed extension must be revised.

By combining GRACE gravity-gradient observations, deep-Earth geophysics, detector-response analysis, and EQT-based state interpretation, this volume provides a cautious framework for re-reading satellite gravity data. It is intended for readers interested in foundational physics, geophysics, gravitational observation, and the methodological question of how existing measurements can be reinterpreted without abandoning the empirical success of classical geophysical model.
