This script reproduces **Figure 6** from the REACS-DI manuscript titled:  
> *Recursive Entropic Architecture for Cosmological Structure with Dimensional Invariance (REACS-DI)*

## Description  
The simulation models a hydrogenic 1s orbital scaled up by ~10³⁵ to compare the resulting spatial point distribution with a random point cloud of equal density.  
It calculates and plots the two-point correlation function for both datasets.

## Requirements  
- Python 3.x  
- `numpy`  
- `matplotlib`  
- `scipy`

Install dependencies using:  
```
pip install numpy matplotlib scipy
```

## Usage  
To run the simulation and reproduce the figure:  
```
python REACS_DI_Simulation.py
```

This will display a plot comparing the scaled hydrogen model with a random distribution.

## Citation  
If you use this script, please cite the REACS-DI manuscript and link to this Zenodo record.
