PFUSRC-090B: Cross-Medium Verification of Biconical Topology

The core axiom of the PFUSRC framework posits that the 45° triple coaxial bicone acts as the scale- and medium-independent fundamental steady-state topological ground state of the entire cosmos. While PFUSRC-090 established cross-scale topological consistency across condensed matter and celestial bodies via the Bitter-Cold Frontier mechanism, this short paper extends validation to heterogeneous material media to verify the universal convergence of biconical geometry under extreme structural constraints. Three entirely disconnected natural systems are analyzed for cross-medium empirical closure: shock-generated ultrahard meteoritic minerals, supercooled double-pyramid ice crystals, and porous rubble-pile asteroid internal frameworks. All three follow a unified evolutionary sequence: extreme mechanical/thermal/gravitational constraints compress four-dimensional flow variables into latent states, triggering boundary topological latching and spontaneous formation of canonical biconical configurations. Impact ultrahard minerals preserve rigid root-end latching residues locked within crystal lattices; supercooled ice abandons dendritic growth and retracts to biconical bipyramid steady states; high-porosity asteroids maintain long-term structural cohesion via invisible biconical skeletons anchored at pore boundaries, resolving the classical mechanical stability paradox of fragmented small celestial bodies. Lithospheric high-pressure shock, cryospheric low-temperature supercooling and low-gravity asteroidal aggregation collectively confirm that biconical topology constitutes the default convergent structural pathway for all matter under limiting boundary conditions, regardless of chemical composition, material phase or spatial scale. This cross-medium evidence reinforces the global universality of the PFUSRC biconical topological paradigm.
