Filamentation and Supercluster Formation in a Three-Phase Etheric Plasma

This work develops a cosmological model in which the large-scale structure of the universe emerges from the three-phase behavior of a frictionless etheric plasma displaced by quarkbases. Depending solely on the local displaced-volume fraction ϕ, the plasma behaves as a rigid, liquid-like, or gas-like medium. These regimes determine the formation of voids, clusters, filaments, and superclusters without invoking dark matter or metric expansion. Filamentation is shown to be a universal hydrodynamic instability, mathematically analogous to cigarette-smoke plumes, arising when the plasma crosses the compressibility threshold. The model predicts a maximum supercluster size of 200–300 Mpc and provides a unified explanation of the cosmic web as a stationary ether-flow network.
