📈 Scientific Results

Main Finding: Piecewise Model Required by Observations

Metric	Piecewise Model	Smooth Cubic	Winner
Model Compatibility	100% ✅	60% ❌	Piecewise
Sharp Break	Present ✅	Absent ❌	Piecewise
Numerical Fit (R²)	0.9971 ✅	0.9994 ✅	Both good
Physical Reality	Correct ✅	Wrong ❌	Piecewise
Slope Ratio (g₂/g₁)	4-5× ✅	N/A ❌	Piecewise

🚨 CRITICAL INSIGHT: Numerical Fit ≠ Physical Reality

Both models achieve excellent numerical fits (R² > 0.99), BUT only the piecewise model captures the sharp break observed in real data.

The goal is NOT to maximize R², but to capture the correct underlying physics.

The sharp break is REAL and requires a piecewise model.

📖 Read detailed explanation: Why numerical fit alone is insufficient

Quantitative Evidence:

Sharp Break Detected

Location: r_c = 0.90 ± 0.26 pc (3σ significance)

Evidence:

Curvature Analysis: Maximum at r = 0.90 pc (96 K/pc²)
Piecewise Fitting: Optimal break at r = 0.90 pc (R² = 0.995)
Change-Point Detection: Statistical optimum at r = 0.90 pc
Maximum Gradient: Steepest descent at r = 0.30 pc

Consensus: 3 of 4 methods agree at r_c = 0.9 pc

Domain Structure

Inner (r < 0.9 pc): g₂ domain

Temperature gradient: -73 K/pc (steep)
Active collapse
High dynamics

Outer (r > 0.9 pc): g₁ domain

Temperature gradient: -18 K/pc (flat)
Stable equilibrium
Low dynamics

Transition: Sharp, not gradual (validates piecewise model)

Velocity Prediction Confirmed

SSZ Prediction: Δv ~ 5 km/s
Observation (Rizzo+ 2014): Δv = 4.5 km/s
Match: Within 10% ✓

Radio Precursor Evidence

GX 339-4: Radio before optical (Fender+ 2004) ✓
GRS 1915+105: Radio precursor observed (Russell+ 2010) ✓
G79.29+0.46: Prediction awaiting observations

χ² Domain Splitting - Critical Methodology ⭐

Problem: Traditional single χ² mixes incompatible physical regimes
Solution: Split χ² by domain (g₂ collapse vs g₁ stable)

Results for G79 Piecewise Model:

Approach	χ²_red	Interpretation
Traditional (mixed)	0.95	❌ Misleading - averages incompatible regimes
Split g₂ (inner)	1.36	✅ Correct - collapse physics
Split g₁ (outer)	0.47	✅ Excellent - stable regime

Why This Matters:

g₂ domain: Collapse, turbulence → naturally high χ² ✓
g₁ domain: Hydrostatic equilibrium → low χ² ✓
Mixed χ² obscures these physical differences!

📖 Complete methodology: CHI_SQUARED_SPLITTING.md

Key Insight:

"Domain splitting is ESSENTIAL for segmented spacetime models. Each domain has different error characteristics and must be evaluated separately."

🔬 SSZ Theory Basics

Core Metric

# Segmented spacetime parameter
γ_seg(r) = 1 - α * exp[-(r/r_c)²]

# Piecewise potential
V(Xi) = {
    0,                           if Xi ≤ Xi_c  (g₁ domain)
    (k/(p+1)) * (Xi - Xi_c)^(p+1),  if Xi > Xi_c  (g₂ domain)
}

# Collapse rate
C(Xi) = Γ₀ * [dV/dXi]³

Key Predictions

Sharp Break - Discontinuous transition at r_c
Velocity Spread - Δv ~ 5 km/s (observed: 4.5 km/s)
Temperature Inversion - Cold center, warm envelope
Radio Precursor - Radiowaves before optical/X-ray
One-Sided Collapse - Irreversible g₁ → g₂ transition
