Description

The Discrete Emergent Gravity (DEG) framework derives macroscopic physics from a single postulate: spacetime consists of N Planck-scale atoms, each carrying g = 442 internal quantum states from an SU(21)×U(1) gauge structure, governed by H = 0. No parameters are fitted to observation at any stage.

Two results are highlighted. The observed cosmological constant Λ = (1.088 ± 0.030) × 10⁻⁵² m⁻² is predicted to 0.17σ via two-loop RG running of the atomic vacuum energy, with UV cutoff set by the emergent micrometre-scale atom spacing. The Higgs boson mass m_H = 124.8 ± 2.4 GeV is derived from the CKM CP-violation phase and the observed baryon asymmetry alone, landing 0.19σ from the PDG value. A single internal parameter φ_DEG simultaneously satisfies seven independent constraints across flavour physics, leptogenesis, and the Higgs sector — none fitted, all derived.

Additional results include exact resolution of the black hole information paradox via a finite-dimensional Hilbert space, derivation of the MOND acceleration scale from first principles, and the SM gauge group and three generations from SU(21) ⊃ SU(5)×SU(16). Near-term falsifiability is provided by normal neutrino mass ordering (JUNO, 3–5 yr), proton decay at τ_p ~ 10³³⁻³⁴ yr (Hyper-K), and CMB non-Gaussianity f_NL ~ 7 at 6σ (CMB-S4). One known tension — the Higgs coupling κ_V deviating 7.2σ from the SM — has an identified resolution pathway pending lattice computation.
