| contents | This work proposes a reconstruction of the quantum field theory (QFT) scattering framework: the path integral governs an interaction kernel region, while the Hilbert space encodes asymptotic free boundary conditions. We critically reexamine foundational assumptions and standard observables of QFT, raising the possibility of a unique vacuum. We also introduce a new thermodynamic perspective on vacuum loop contributions. The motivation behind certain vacuum energy cancellation schemes is reconsidered, and the applicability of QFT to spacetimes without asymptotic flatness, such as de Sitter (dS) space, is questioned at a fundamental level. |
