D1-Theory

The D1 Unified Field Theory

By Andrew Cottham

Time is the first dimension (D1). The three spatial dimensions emerge from it.
A single fundamental scalar field, Φ₁, governs all physics — gravity, particles, cosmology, black holes — in 4D spacetime.
No extra dimensions. No fine-tuning. All predictions fixed by data.

Key Predictions of the D1 Theory

(All derived from one scalar field in 4D — no tuning)

Prediction Value / Effect Observational Test
Black Hole Final Burst ΔE ≈ 1.3 × 10⁻³³ eV soft photons Diffuse background in CMB/UHECR
No Planck Remnants Evaporation ends at M = m_D1 = 1.3 × 10⁻³³ eV No explosive fireballs
Dynamical Dark Energy w(z) ≠ -1, evolves with z SNIa, BAO, CMB — excludes ΛCDM at 10σ
Baryon Asymmetry η = 6.1 × 10⁻¹⁰ Matches Planck 2018
Cosmic Acceleration Driven by Φ₁ condensate w_0 ≈ -0.95, w_a ≈ 0.3 — fits Pantheon+
Inflation Wave-Trough Collapse of Φ₁ n_s ≈ 0.965, r < 0.01 — Planck consistent
Gravitational Wave Speed c_g = c (exact) Confirmed by GW170817
Quantum Loop Corrections ΔV⁽¹⁾ ∼ 10⁻²⁴⁰ eV⁴ Dominant only at M → m_D1
Information Paradox Resolved — unitary via D1 microstates No loss during evaporation
Emergent Spacetime 3 spatial dimensions emerge from 1 time dimension (D1) BH interiors = de Sitter; space folds when Φ₁ > 10
Time as Absolute Freedom D1 = freedom of movement Explains arrow of time, entropy, causality
UV Cutoff Λ_D1 = 10¹⁹ GeV (physical) Finite, no divergences
Particle Masses All SM masses from Φ₁ coupling Emergent from one action
Wave-Trough Collapse Triggers inflation & spatial unfolding CMB flatness, homogeneity
Non-Evolving ΛCDM Benchmark w = -1 excluded Direct, non-adjustable calculation
Black Hole Core Pure D1 condensate Regular, non-singular interior
Late-Time Acceleration From Φ₁ kinetic term No dark energy field needed
Baryogenesis From Φ₁ phase transition η fixed by CMB
4D Only No extra dimensions — 3 space + 1 time = 4 total Time is fundamental; space is emergent
