Λ as a Geometric Force - A Combinatorial Reframing of the Cosmological Constant

This short conceptual note introduces a geometric interpretation of the cosmological constant Λ that is fully compatible with GR and ΛCDM. Instead of treating Λ as a physical substance or an unexplained constant, the paper frames it as a geometric force—an inevitability arising from a simple combinatorial doubling rule in a dual‑layer description of spacetime. The metric layer remains entirely standard, while a non‑metric combinatorial layer grows faster, producing a small, constant curvature term interpreted as Λ. This brief paper is intended as a gentle, metric‑friendly reframing for cosmologists interested in the origin and behavior of Λ. v1
