The Hub and How It Works: Dark Matter, Dark Energy, Quantum Mechanics, Black Holes, and Complexity from One Geometry

We describe a geometric structure — the hub — derived from M-theory in the Randall-Sundrum warped extra dimension framework at the single dimensionless parameter kL ≈ 37. The hub is a central node from which seven warped intervals radiate. We show that this structure produces, without additional free parameters: (1) a dark matter gravitational signal consistent with the observed 85:15 mass ratio; (2) an apparent cosmic expansion consistent with dark energy observations; (3) the indeterminacy structure of quantum mechanics; (4) a topographic energy landscape across the observable universe; (5) a geometric account of black holes as a local collapse to flat geometry and a precise description of the information problem; and (6) a geometric bias toward increasing complexity over time. The value kL ≈ 37 is fixed independently by the electroweak hierarchy problem and is not adjusted to fit any of these predictions.
