Cosmological Division as the Consequence of Universal Structural

This work presents the foundational cosmological interpretation of the BECU–OLON framework, where the Big Bang is not treated as an initial singular explosion, but as a cosmological division triggered by universal structural instability. The central quantity is the structural parameter K = (R/ρ)(dρ/dR), with the universal critical threshold Kcrit = √3 ≈ 1.732051. When the universe approaches this threshold after rotational death, black hole saturation, and large-scale structural compression, a phase inversion occurs and a new observable universe emerges. This establishes the sequence: Death of Rotation → Critical Lock → Cosmological Division (BOOM). In this framework, dark matter and dark energy are reinterpreted as geometric structural responses rather than hidden substances or fundamental cosmological constants. Galaxy dynamics, BTFR slope ≈ 4, morphology-dependent lensing offsets, low-ℓ CMB suppression, and late-time cosmic acceleration are unified through the same structural criticality mechanism. The Big Bang is therefore redefined as the beginning of visibility rather than the beginning of existence. Observable universes form a recursive structural sequence rather than originating from an absolute first singularity. BECU–OLON proposes a geometry-driven cosmology where the universe is structurally renewed, not created from nothing.
