The cosmological constant Lambda appears in Einstein's field equations as a term whose physical identity hasnever been conclusively established within the standard model. The standard identification of Lambda with darkenergy — a repulsive vacuum energy density — produces the cosmological constant problem: a 10¹22discrepancy between the quantum field theory prediction for vacuum energy and the observed value. Nosatisfactory resolution exists within the standard model framework. This paper argues that the problem arises from a false identification. Within the Big Flare-Up Theory (BFUT), Lambda is not dark energy. Lambda is first the mathematical signature of spatial infinitude — the necessary termthat appears in the field equations precisely because the universe is infinite, has no boundary, and has no uniqueglobal centre. Once spatial infinitude is the primary identity, a secondary physical identity follows: Lambda is themeasurable signature of the Spaticle field, the physical substrate of space-time whose existence is required bythe confirmed physical behaviour of space under general relativity. The energy density of the Spaticle field is derived directly from the observed value of Lambda using onlyestablished physics: rhoSpaticle = Lambda c² / (8 pi G) approximately 5. 9 x 10^-27 kg/m³. This value iswithin a factor of 1. 68 of the observed mean matter density of the universe (9. 9 x 10^-27 kg/m³), dissolving thecoincidence problem as well as the cosmological constant problem. No free parameters. No quantum corrections. No tuning. The 10¹22 discrepancy is not a failure of nature to match theory. It is a consequence of equating twophysically distinct categories. BFUT removes the category error that generates the apparent contradiction. This paper is a companion to the main Big Flare-Up Theory paper (DOI: 10. 5281/zenodo. 19149786).
