GLOBAL SCALE AND THE NON-CAUSAL STATUS OF THE COSMOLOGICAL CONSTANT

This paper addresses the global-scale cosmological constant problem under a strict mechanism-only framework. It asks whether a globally defined parameter can physically enforce expansion across arbitrarily large spatial scales when admissible causes are restricted to local energy–momentum exchange with reciprocal back-reaction. Applying enforcement and removal tests, the paper shows that the cosmological constant does not exchange energy or momentum, does not propagate influence through physical interaction, and does not undergo back-reaction with matter or radiation. Removing it leaves all physically enforcing mechanisms intact, while removing local exchange collapses physical behavior entirely. The paper concludes, by logical necessity, that the cosmological constant cannot function as a global physical cause and is instead a descriptive parameter, without denying observed cosmic expansion or the mathematical utility of Λ in large-scale modeling.
