**Preprint | Continuum Field Entropy Empirical Validation Series** The 2017 Event Horizon Telescope (EHT) observation of M87* is widely interpreted as the geometric shadow of a spinning singularity governed by the Kerr metric of General Relativity (GR). This standard model assumes light is a discrete ballistic particle (photon) traveling on a null geodesic, which mandates an infinitesimally thin ring at the critical impact parameter. In this paper, we challenge the particle nature of light and the empty geometry of the vacuum. Using the Continuum Field Entropy (CFE) framework, we model the vacuum as a viscous Cosserat continuum field and light as a continuous transverse wave. In the extreme tension gradient of a supermassive core, the field’s vibration capacity collapses (0), causing the effective wave speed to drop asymptotically to zero (c₄₅₅ 0). The spatial circumference is physically stretched, resulting in a non-Euclidean geometry (C (r) < 2 r). We hypothesize that the M87* ring is a thick Laminar Waveguide trapped by severe optical refraction, not a geometric particle shadow. Executing a 20, 000-step Hamiltonian MCMC inference over the raw EHT M87* visibility amplitudes, we isolate a fractional width of W/d = 0. 518 0. 000, aggressively rejecting the GR zero-thickness prediction. We conclude that black hole singularities are mathematical artifacts; the physical reality is a thermodynamic continuum undergoing continuous seizure. **Project Integration: **This document is a standalone validation report.
