   Higher-Dimensional Coordinates
   While macroscopic reality is typically modeled in three spatial dimensions, many advanced physical theories necessitate the use of additional coordinates. Kaluza-Klein theory, for instance, postulates a fifth dimension curled into a compact manifold. While these extra dimensions are not directly accessible via standard spatial coordinate measurement (i.e., the extra dimensions exhibit maximal chromatic opacity), their influence on the three ob…
