What is a voxel?

---

  A voxel is a discrete, elastic, causally active unit that composes the underlying structure of space itself.  Unlike mathematical points, which are dimensionless abstractions, or classical aether models, which rely on  continuous media, voxels are real, finite, and structurally persistent. 

  Each voxel possesses both a fixed minimum and a fixed maximum size, defining natural physical limits beyond which  deformation or compression cannot proceed.  Voxels cannot be split into smaller units, nor can they be compressed into dimensionless points.  Each voxel retains all three spatial dimensions at all times, preserving the tangible, causal structure of space at every scale. 

    A voxel occupies a specific, tessellated position within the fabric of physical reality, seamlessly adjoining neighboring  voxels in all directions. The size and behavior of each voxel are not governed independently, but are determined jointly by the principle of  action and by the cumulative tension, deformation, and saturation conditions imposed by all adjacent voxels.  Thus, voxels are inherently relational: their state, motion, and causal behavior arise from both internal properties and local field pressures transmitted through the tessellated structure. 

     The surface topology of each voxel is defined by a geodesic geometry, minimizing internal tension and maximizing  elastic causal transmission across its boundary.  This geodesic topology ensures that interactions between adjacent voxels occur with minimal loss of causal  structure, enabling efficient propagation of tension, compression, and deformation.  Voxels do not exist within space — they are space.  All observed fields, particles, forces, and inertial behaviors arise from the deformation, tension, saturation, and  relaxation of voxels under causal constraint.  In Voxel Theory, space is a tessellated, causal, elastic medium — not a void, nor an abstract manifold — but the active substance of existence itself.
