Inhoudsopgave:
- <p>This manuscript is currently under review at Foundations of Physics.</p> <p>This paper is part of a research program proposing that the cosmological constant arises not from total vacuum energy but from the finite-domain residual to which gravity actually couples.</p> <p>This paper develops the first component of a research program examining the consequences of finite-domain vacuum energy for the cosmological constant problem.</p> <p>Physical observation is fundamentally constrained by coupling. All measurement systems possess finite bandwidth, finite sensitivity, and specific interaction channels, ensuring that only a restricted subset of underlying degrees of freedom becomes accessible to observation. This paper develops a conceptual and formal framework based on this principle, treating observable quantities as bandwidth-limited projections of a more extensive underlying substrate.</p> <p>Within this framework, the physical vacuum is reinterpreted not as empty or minimally structured but as a maximally symmetric ground state comprising the full zero-point energy of all quantum field modes in balanced superposition. The energy content of this ground state is physically real — confirmed by phenomena such as the Casimir effect, the Lamb shift, and spontaneous emission — but its totality is not accessible to any finite coupling interaction. Observable structure emerges only when coupling, symmetry-breaking, or interaction selects particular subsets from the full mode spectrum. The framework identifies two jointly operating layers of observational constraint — bandwidth limitation and symmetry cancellation — and develops a toy model (a free scalar field coupled to a finite-bandwidth detector) to illustrate how coupling constraints yield a small observable residual from an underlying state of extensive energy content.</p> <p>The framework provides a coherent interpretive basis in which observable vacuum energy corresponds to a coupling-dependent residual rather than the totality of underlying energy. It does not modify established dynamical laws but proposes a revised interpretive foundation for understanding the relationship between measurement, vacuum structure, and observable physical reality. Connections to effective field theory, decoherence, and algebraic quantum field theory are discussed.</p> <p>Series Overview</p> <p>This paper forms part of the Finite-Domain Vacuum Energy research program, a series of theoretical studies examining the cosmological constant problem — the approximately 10^120 discrepancy between quantum field theoretic estimates of vacuum energy and the observed value of dark energy.</p> <p>The central thesis of the series is that this discrepancy arises from a category mismatch between two fundamentally different quantities: the total vacuum state-energy of an idealized infinite domain and the residual vacuum energy that survives symmetry cancellation within the finite causal domain of the physical universe. Within this framework, gravity couples not to the total vacuum energy but to this finite-domain residual.</p> <p>The series develops the framework progressively. Early papers establish the conceptual and observational foundations of finite-domain vacuum energy, subsequent papers derive gravitational consistency constraints and cosmological scaling relations, and later papers explore the implications for cosmology, particle content, and horizon thermodynamics.</p> <p>Together the papers argue that the observed cosmological constant can be understood as the gravitationally operative residual of quantum vacuum structure within the finite physical universe.</p>
