=== Psi Field Stress-Energy Tensor Equation ===
<math>
T^{\mu\nu}_{\text{psi}} = \varepsilon_{\text{psi}} c^2 u^\mu u^\nu + p_{\text{psi}} g^{\mu\nu}
</math>
* Description: This equation defines the stress-energy tensor (<math>T^{\mu\nu}_{\text{psi}}</math>) for the Psi Field, analogous to stress-energy tensors in general relativity. The first term represents the energy density (<math>\varepsilon_{\text{psi}}</math>) of the Psi Field, scaled by the speed of light squared (<math>c^2</math>) and the 4-velocity (<math>u^\mu</math>). The second term represents the pressure (<math>p_{\text{psi}}</math>) of the Psi Field, scaled by the metric tensor (<math>g^{\mu\nu}</math>). The stress-energy tensor describes the distribution of energy, momentum, and stress within the Psi Field.
