Stabilizing Quantum Gravity (SQG): Emergent Spacetime, Gauge Symmetry, and Matter from Recoverable Quantum Codes

This document presents the Stabilizing Quantum Gravity (SQG) research program: a unified quantum-information and operator-algebraic framework in which spacetime, gravity, gauge structure, matter, chirality, and cosmological dynamics emerge from a deeper recoverable logical substrate. Crucially, this release marks the transition of SQG from a structural framework into a computational, predictive architecture. SQG no longer merely proposes mechanisms; it outputs finite, checkable numerical benchmarks across particle physics and cosmology. At its core, SQG advances a radical but disciplined claim: Physical reality is not fundamentally built from pre-given spacetime, primitive particles, or externally imposed gauge laws. It is built from recoverable, stabilizable logical structure. In this view, the universe is not a static stage populated by objects. It is a self-organizing quantum-logical architecture whose stable sectors appear as geometry, whose redundancies appear as gauge symmetry, and whose localized failures appear as matter. Core Vision & Computable Targets Geometry is not fundamental. It emerges as the large-scale phase of successfully stabilized logical sectors. Gauge structure is not postulated. It appears as a redundancy of admissible recoverable organization. Matter is not primitive. It arises as defect structure: localized failures or frustrations of stabilizer recovery. Fermion Generations are not inserted by hand. The existence of exactly three generations (N₆₄₍ = 3) is algorithmically extracted from the modular commutant equations (SN=NS, TN=NT) of the underlying protected defect category. Mass Hierarchies are computable. Flavor hierarchies (e. g. , the exact e, , lepton mass ratios) are demonstrated to follow a strict exponential scaling law governed by the topological complexity (Dₐ) of the corresponding defect sectors. Dark Energy is not a cosmological constant (). It is the macroscopic manifestation of the dynamical stabilization flow (QS). Simulations show the effective equation of state naturally driving toward w₄₅₅ -1 at late times, providing a natural resolution to the Hubble Tension (H₀). Dimensionality is a dynamical attractor. Random-walk diffusion on the SQG stabilizer graph exhibits UV spectral-dimension flow, transitioning from dₛ 2 in the quantum ultraviolet to dₛ 4 in the macroscopic infrared, matching established non-perturbative quantum gravity benchmarks. Why the Chirality Problem Matters One of the hardest bottlenecks in all deep reconstruction programs of matter is chirality. Many frameworks can talk elegantly about topology, emergence, entanglement, or defects. Very few can say, with real mathematical discipline, how protected chiral low-energy sectors could actually arise. This is exactly where many otherwise beautiful theories quietly fail. SQG does not pretend this problem is trivial. On the contrary, it treats chirality as one of the central structural tests of the whole framework. The proposal is that chirality should not appear as a property of a homogeneous bulk alone, and should not be inserted by hand as an unexplained asymmetry. Instead, it is addressed through a bulk–defect mechanism: Inequivalent recoverable phases define the adjacent bulk sectors, Admissible interfaces between them carry protected defect degrees of freedom, A projected Floquet operator (M = PUFP) defines the relevant chiral sector, A Fredholm defect index (_) measures the net chiral content, locked to the bulk inflow anomaly. In that formulation, chirality becomes an index-theoretic and bulk–defect problem, rather than a miraculous extra ingredient. This is one of the most ambitious parts of the SQG program, because it attempts to turn one of the least tractable asymmetries in fundamental physics into a theorem-level construction problem with explicit closure conditions.
