Quantum Gravity Theory: Based on Inverted Relativity

We present a unified effective-field-theoretic framework for emergent gravity in which
spacetime curvature, gravitational mass, inertial response, and large-scale electromagnetic
spectral organization arise from a single scalar-modulated vacuum dynamics defined on a
fundamentally flat Minkowski background. No fundamental spacetime geometry or gravita-
tional interaction is postulated. Instead, all microscopic dynamics take place on Minkowski
space, while geometric notions emerge only as macroscopic descriptors of vacuum response.
The theory is built around a light pseudo-Goldstone scalar field ϵ(x) whose radiatively
protected, parity-even conformal coupling induces a universal modulation of inertial and
gravitational mass while suppressing linear scalar charges and long-range fifth forces. Grav-
itational phenomena are described through an Inverted Relativity mechanism: the quantum
dynamics of ϵ are fundamental, whereas the effective spacetime metric is a composite, non-
dynamical object encoding the infrared constitutive response of the vacuum. No metric
variation or quantization is performed at any level.
Renormalization acts exclusively on the emergent effective-field-theoretic description.
Curvature terms, including an induced Einstein–Hilbert contribution, arise through Sakharov-
type ultraviolet–infrared matching when microscopic fields are integrated out, and serve only
to fix infrared response parameters rather than to define a fundamental gravitational inter-
action. As a result, the framework is ultraviolet complete without quantizing spacetime or
introducing fundamental gravitational degrees of freedom.
Semiclassical gravitational dynamics emerge from vacuum expectation values and a loop-
generated effective scalar potential, with deviations from General Relativity confined to
regimes of high curvature or strong scalar gradients. The electromagnetic sector is extended
by the Electromagnetic Spectral Effective Model (ESEM), a macroscopic constitutive descrip-
tion fully compatible with quantum electrodynamics, which predicts the existence of Local
and Global Equilibrium Spectral Points. Within this framework, the cosmic microwave back-
ground appears as the Global Equilibrium Spectral Point, interpreted as a universal spectral
attractor of the scalar-modulated vacuum rather than as a relic of geometric expansion.
Taken together, these elements define a mathematically consistent, radiatively controlled,
and observationally testable framework in which gravity, geometry, and large-scale electro-
magnetic structure emerge from a common scalar-driven vacuum dynamics on flat spacetime.
