This paper extends the U(1) quantum gravity (QG) model, originally proposed in Cook (2013) and refined in Cook (2025), by integrating compatible insights from Ford’s "FAVE: An Emergent Gravity Framework" and Schubert’s "Einstein and Jacobson in the Elevator" (2025). The U(1) model posits that spin-1 gravitons mediate both repulsive dark energy and attractive gravity, with off-shell paths geometrically cancelled in a Feynman path integral, yielding a simple 2-vertex scattering cross-section. We reject entanglement-based modifications as non-relativistic artifacts, instead reinterpreting Ford’s gravitational profile and structure formation adjustments, and Schubert’s thermodynamic consistency, within our relativistic second-quantization framework. These extensions preserve the model’s core simplicity, enhance its explanatory power for black holes and cosmology, and propose new testable predictions without introducing unnecessary complexity.

We explore a proposal for emergent gravity grounded in the interplay between area—law and volume—law entanglement contributions in quantum field theories. By tracing the well—known area—law behaviour of entanglement entropy in ground states, we introduce a scalar field σ that tracks the local entanglement density. This effective field remains negligible when the system’s entanglement adheres to the standard (boundary) area law, reproducing General Relativity (GR). However, once excitations increase the entanglement beyond a critical threshold, volume—law contributions become significant, and σ acquires a non—trivial potential that modifies the Einstein field equations. We show how this framework—dubbed the Ford—Area/Volume Emergent (FAVE) model—can mimic dark matter and dark energy phenomena by "smearing" mass—energy in high—entanglement regions, thereby altering cosmological expansion and structure formation. We apply this idea to mass—to—light ratio measurements in galaxy clusters, revealing that entanglement—driven corrections can provide a consistent fit to observations while reducing the need for separate dark components. Finally, we discuss possible implications for black hole interiors, highlighting how a 1/r entanglement contribution might remedy singularities through an effective redistribution of energy. Our results serve as a preliminary validation of FAVE as a unified approach to tackling both large—scale structure and black hole physics from an entanglement—theoretic perspective.

This paper presents a quantum gravity model where dark energy, mediated by a U(1) spin-1 graviton, drives both cosmological acceleration and gravitational attraction. Using Feynman’s perturbative expansion, we show that at low energy, the dominant tree-level interaction (analogous to Moller scattering in QED) yields a graviton-proton scattering cross-section of σg−p ≈ 10^{−108} m^2, consistent with π(2GM/c^2)^2. This predicts a cosmological acceleration a = (c^4)/(Gm), aligning with Riofrio’s empirical law tc^3 = Gm. Gravity emerges as a secondary effect of the inward reaction force to dark energy, intercepted by the cross-section of a mass, as illustrated geometrically. Originally published in 2013, this work is revisited with diagrams reinterpreted by Grok 3, an AI developed by xAI, to enhance clarity and accessibility.

This paper presents a revolutionary framework for theoretical physics, unifying gravitation, dark energy, and electrodynamics under a U(1) gauge theory mediated by spin-1 gravitons. We replace general relativity’s spacetime curvature with a repulsive dark energy force, interpreting gravity as a LeSage/Casimir-type shielding effect of isotropic repulsion. Dark energy drives cosmological acceleration, while gravity emerges as a net attraction, due to geometric shielding. Electrodynamics is revised, with charges radiating massless gauge bosons akin to Hawking radiation, predicting the fundamental constants. Particle masses are derived via a shell model, matching observations (e.g., proton: 945 MeV predicted vs. 938 MeV observed; lightest neutrino: 0.00012 eV predicted). The gravitational theory replaces inflation by explaining flatness (Ω ≈ 1). New predictions include evolving dark energy density, distinct gravitational wave signatures from spin-1 gravitons, and a neutrino mass of 0.00012 eV. Supported by empirical evidence (e.g., cosmological acceleration, LEP running couplings), this model offers testablepredictions: time-varying G via pulsar timing, linear expansion and Hubble variation via supernovae and DESI, gravitational wave signatures via LISA, and neutrino mass via KATRIN. We contrast this with entropic gravity and MOND, highlighting the U(1) framework’s quantum foundation and cosmological consistency, justifying a paradigm shift in physics.

We revisit Verlinde’s entropic gravity by reversing its conceptual direction. Instead of deriving gravity from entropy gradients on a holographic screen, we interpret the screen as the thermodynamic projection of a field Phi — an event horizon interface where quantum information becomes classically readable (Schubert A. 2025). No entropic force is required; gravity appears as a thermodynamic imprint of informational asymmetry.Building on the Unruh effect and the behavior of self-heating systems in free fall, we identify the central peak of Phi as an informational event horizon: a region of entropy-neutral superposition, where quantum states remain undecided until an entropy gradient emerges. Projection is not driven by decoherence, but by thermodynamic symmetry breaking. Verlinde’s force law remains valid in form, but becomes a diagnostic expression of projection — not its cause.Our framework aligns naturally with entropic quantum gravity (EQG) models such as Bianconi’s, in which geometry and time emerge from information constraints. The EH field Phi offers a classical realization of this idea, embedding quantum information and thermodynamic projection within a dual AdS/dS geometry. Rather than replacing Verlinde’s insight, we unfold its deeper structure - from coherence to curvature.

We propose a novel hypothesis that time is an emergent effect of the universe’s computa-tional rendering complexity. In this framework, pure energy represents the universe’s fastestoperational state with no temporal delay, while matter and gravity introduce complexitythat increases rendering latency, manifesting as time dilation. We show that this model ismathematically consistent with special and general relativity, and we explore its implicationsfor black hole physics, the early universe, and quantum computational limits. These resultsprovide a clear path toward visual, numerical, and potentially empirical validation of thetheory.
