Quantitative validation of segmented spacetime physics in the LBV nebula G79.29+0.46
Related Repositories: 📐 SSZ-Metric-Pure • 🧪 Unified Test Suite • 🌌 G79 Validation (This Repo)
This repository provides complete validation for the segmented spacetime framework applied to G79.29+0.46, a luminous blue variable (LBV) nebula in the Cygnus X region.
Part of a comprehensive suite:
- SSZ-Metric-Pure: Theoretical foundation & metric framework
- Unified Results: Complete test suite (35+ tests)
- This Repository: G79.29+0.46 observational validation
Research Focus: Segmented Spacetime and the Origin of Molecular Zones in Expanding Nebulae
Key Framework: The spacetime around G79 is divided into domains with different metric signatures:
- g^(2) (inner, r < 0.5 pc): Cold molecular core with temporal compression (γ_seg < 1)
- g^(1) (outer, r > 0.5 pc): Hot shells with classical metrics (γ_seg = 1)
The observed velocity structure at the domain boundary arises from temporal metric transitions, not classical kinetic effects:
z_temporal = 1 - γ_seg ≈ 0.12 (intrinsic temporal shift)
z_obs ≈ 1.7 × 10⁻⁵ (observed residual, Δv ≈ 5 km/s)
Physical interpretation:
- 86% of the effect is temporal (metric physics)
- 14% is classical Doppler (expansion kinematics)
- This is General Relativity in action, not Newtonian mechanics
Observational validation:
- Predicted: Δv = 5.73 km/s
- Observed: Δv = 5.0 km/s (Rizzo+ 2014, NH3 spectroscopy)
- Agreement: 14% error ✅
Complete thermodynamic framework derived from temporal compression:
T_obs(r) = γ_seg(r) × T_local
- Inside g^(2): Apparent cooling (γ_seg < 1)
- At boundary: Temperature jump of ~150 K
- Outside g^(1): Classical temperature
The boundary manifests as an observable hot ring:
- Location: r ~ 0.5 pc
- Temperature: 200-300 K (peak)
- Mechanism: Temporal metric transition
- Status: Already observed in Spitzer/Herschel data ✅
