The Spiral Universe Model as an Einstein-Evolved Bianchi VII(_h) Cosmology Download PDF Abstract The  Spiral Universe Model  (SUM) is a relativistic cosmological framework in which the large-scale universe is represented by an organized Bianchi VII_h-type geometry rather than being restricted to exact FLRW isotropy. Its defining ingredients are anisotropic expansion, spatial curvature, shear, matter tilt, dynamically generated vorticity, and regional cosmic flows. SUM retains Einstein’s field equations as the fundamental gravitational law: Gμν = 8πG Tμν while defining the tested cosmological sector by: Λ = 0 ρCDM = 0 These are model postulates. No cosmological-constant term and no separate cold-dark-matter fluid are inserted into the fundamental SUM equations. Ordinary matter remains present through Tμν. The recent numerical development of SUM has moved the model beyond its earlier phenomenological form. Four increasingly stringent relativistic tests have now passed. Test I es...

Cosmic Vine: The Blueprint of Cosmic Rotation

Image
The recent identification of the Cosmic Vine by the James Webb Space Telescope (JWST) has fundamentally shifted our understanding of the universe's large-scale architecture. Long thought to be static, passive "bridges," the filaments of the cosmic web are now being revealed as dynamic, rotating engines of galactic evolution. This structure—a chain of 130 massive galaxies stretching 13 million light-years—serves as the primary evidence for a new era of Density Wave cosmology. I. The Discovery of the Vine and the Leaf Initially identified in late 2023 and further analyzed through early 2026, the Cosmic Vine is a "protocluster"—a gargantuan ancestor to modern galaxy clusters. Found at a redshift of $z = 3.44$ , we are seeing this structure as it existed a mere 1.8 billion years after the Big Bang. Dimensions: It is an extremely elongated filament, roughly 13 million light-years long but only 650,000 light-years wide. The "Leaf" Branching: Recent 20...
