=== Energy Density Tensor ===
The distribution of energy within Nexus Worlds is described by an energy density tensor that extends the traditional energy-momentum tensor to account for Nexus-specific contributions:

<math>T^{\mu\nu}_{\text{Nexus}} = \rho u^\mu u^\nu + p\left(g^{\mu\nu} + \frac{\delta N^{\mu\nu}_{\text{Nexus}}}{c^2}\right)</math>

Where:
* <math>\rho</math> is the energy density.
* <math>u^\mu</math> is the four-velocity of the energy flow.
* <math>p</math> is the pressure.
* <math>\delta N^{\mu\nu}_{\text{Nexus}}</math> is the Nexus Energy Field contribution to the stress-energy tensor.

This tensor provides a comprehensive description of how energy is distributed and flows within a Nexus World, accounting for both conventional and Nexus-specific effects.
