## Overview

This repository contains the complete computational toolkit for the 3D+3D Discrete Spacetime Theory, a framework proposing six-dimensional spacetime (3 spatial + 3 temporal dimensions) as an alternative explanation for dark matter phenomena.

**Key Feature: ZERO FREE PARAMETERS PER OBJECT**

All predictions use only universal constants derived from the theory's geometric structure.

## Installation

### Requirements

```bash
pip install numpy scipy matplotlib
```

### Optional (for enhanced performance)

```bash
pip install numba  # JIT compilation for screening solver
```

## Quick Start

### 1. Verify Constants

```python
from constants import print_summary, BreathingScales

print_summary()
BreathingScales.print_ladder()
```

### 2. Rotation Curve Analysis

```python
from rotation_curve_3d3d import RotationCurve3D3D

# Create galaxy model
model = RotationCurve3D3D(
    M_disk=5e9,    # M_sun
    R_disk=2.5,    # kpc
    M_gas=3e9,     # M_sun
    R_gas=7.5      # kpc
)

# Compute and plot
model.plot(R_max=25)
```

### 3. Gravitational Lensing

```python
from gravitational_lensing import SLACSAnalysis

analysis = SLACSAnalysis()
results = analysis.analyze_sample()
analysis.plot_results()
```

### 4. Cosmic Web Scale

```python
from cosmic_web_analysis import CosmicWebMock

mock = CosmicWebMock(n_galaxies=10000, lambda_13=0.856)
coords = mock.generate()
cf, detection = mock.analyze(coords)
```

## Key Physical Parameters

### Universal Constants (FIXED)

| Parameter | Value | Description |
|-----------|-------|-------------|
| λ₂ | 4.30 kpc | Fundamental breathing scale |
| β | 0.49 | Coupling constant |
| φ | 1.618... | Golden ratio |

### Compactification Radii

| Dimension | Radius | Period |
|-----------|--------|--------|
| τ₂ | L₄ = 15.1 ly | T₂ = 30 yr |
| τ₃ | L₅ = 9.6 ly | T₃ = 19 yr |

### Breathing Scale Ladder

```
λₙ = λ₂ × φ^(n-2)

n=2:  λ₂  = 4.30 kpc   (SPARC fundamental)
n=4:  λ₄  = 11.7 kpc   (SLACS scale)
n=13: λ₁₃ = 0.856 Mpc  (Cosmic web)
```

- **RMS:** 15-33 km/s
- **Free parameters per galaxy:** 0

### SLACS Gravitational Lensing (73 lenses)
- **R ≡ θ_E,3D3D / θ_E,GR:** 0.749 ± 0.034
- **Agreement:** < 1σ

### NANOGrav Pulsar Timing
- **T₂/T₃ = 30/19 = 1.579 ≈ φ = 1.618**
- **Agreement:** 97.6%

### DESI Cosmic Web
- **λ₁₃ predicted:** 0.856 Mpc
- **Observed:** 0.85 ± 0.20 Mpc
- **Agreement:** 0.03σ
