Abstract

This book presents a foundational ontological reconstruction of gravity within the Energy Quantum Theory (EQT), proposing that spacetime is not a physical background but an emergent process arising from the low-frequency segment (\(f < 10^3\,\text{Hz}\)) of the energy quantum density field \(\rho(\mathbf{r}, t, f)\)—time corresponds to \(\partial_t \rho\), and space to \(\nabla \rho\). Gravity is thereby reinterpreted not as the curvature of a geometric manifold, but as a statistical gradient effect of low-frequency energons, fully abandoning the metric ontology of general relativity. This framework is grounded in the frequency-first principle established in Book 8, Planck's Unfinished Radiance, and operationalized through (Postulate II: the Gradient Flow Postulate), which unifies all forces under the dynamical law \(\mathbf{F} \propto -\nabla \rho\). The work further develops (Inference 5: the Quantum–Gravity Unification Mechanism), predicting that Planck-scale fluctuations imprint observable signatures on macroscopic scales via nonlinear cascades—offering a concrete physical interpretation for the stochastic gravitational wave background potentially detectable by LISA. As the second volume in the four-part physical core (Books 1–4), this book extends the high-frequency unification of Energy Quantum Theory (KAIEQT) into the gravitational domain, providing the spacetime–gravity foundation for The Quantum Energy Universe (KAITQE)’s dark sector synthesis and The Universe of…
