Step-by-Step Verification of the OCEAN Model: Analytical Derivation of Black Hole Shadow Diameters (Sgr A* and M87*)

This report provides a rigorous step-by-step verification of the Viscous Fermionic Condensate (OCEAN) model. We demonstrate that the observed diameters of the shadows for M87* and Sagittarius A* are direct consequences of the model’s rheological parameters. The calculation follows a deterministic 4-step path: Mass → V-Horizon → Lensing → Observed Diameter.

Abstract

This report provides a rigorous step-by-step verification of the Viscous Fermionic Condensate (OCEAN) model. We demonstrate that the observed diameters of the shadows for M87* and Sagittarius A* are direct consequences of the model’s rheological parameters. The calculation follows a deterministic 4-step path: Mass → V-Horizon → Lensing → Observed Diameter.
