Resonant Spacetime Hypothesis 2.0

Delaunay Tessellation Field Estimator (DTFE)

```python  

from scipy.spatial import Delaunay  

def dtfe_density(particles, grid_size):  

    tri = Delaunay(particles)  # Tessellate particle positions  

    density = np.zeros(grid_size3)  

    for i, tetra in enumerate(tri.simplices):  

        vol = tri.volume(i)  

        density[tetra] += 1 / vol  # Mass-weighted density  

    return density.reshape((grid_size,)*3)
