Directional Cosmology of the Rotating Universe

This document proposes a new coherent and geometric interpretation of the structure of the Universe: directional cosmology. It demonstrates that solar systems, galaxies, cosmic filaments, and superclusters are not independent structures, but the fractal manifestations of a single fundamental phenomenon: the rotation of the cosmic fluid. By treating space‑time as a rotating fluid, the document unifies phenomena that are usually considered separately — the formation of solar systems, the spiral arms of galaxies, the organization of filaments, CMB anisotropies, and accelerated expansion — under a single dynamic: the vortex. The work establishes a clear hierarchy: local vortexes (solar systems), massive vortexes (galaxies), intergalactic vortexes (filaments), global vortex (the Universe). It also explores the possibility of a directional cosmic center, potentially beyond our causal horizon, and identifies the observable signatures of universal rotation. This document forms a complete theoretical foundation for a fluid, fractal, and directional cosmology, opening the way to a profound reinterpretation of cosmic dynamics.
