The Pressurized Universe

Conventional physics treats interstitial space as a vacuum or near-vacuum, an assumptioninherited from the sensory limits of the human scale rather than derived from firstprinciples. In the Cohesion UFT, this assumption is incompatible with the causalstructure of recursion. The foundational axiom that the observable universe is underpressure from the next higher scale requires Ps > 0 at all accessible scales. Surplus,collapse, torsion, slip, and continuance operate only under non-zero pressure; a truevacuum Ps = 0 eliminates deformation, recovery, identity, and motion. This paperformalises the pressurised universe boundary condition and demonstrates that a zeropressure universe cannot sustain recursion, coherence nodes, or stable structures.Three results are established. First, the asymptote result: operator activity does notvanish as local substrate density approaches zero but asymptotes to a lower bound setby the inherited pressure from the next higher scale, limρs→0 activity = f(Ps+1) > 0.Second, the operator collapse table: each operator in the Cohesion set becomes undefinedunder Ps = 0, demonstrating the geometric necessity of non-zero pressure. Third, thescale-relative misinterpretation: the vacuum is a detection threshold artefact, not aphysical state. Many cosmological anomalies attributed to dark energy, vacuum energy,or spacetime curvature are predicted by the framework to arise from misinterpretinglow-density recursion as emptiness; quantitative testing of these predictions requiresthe calibration of the variable-propagation function R(Dst), which remains the openprogramme. The non-zero pressure boundary condition is necessary for the Cohesionoperator set to remain defined; the precise functional form of the pressure hierarchy isidentified as an ordering axiom requiring explicit statement alongside the foundationalaxiom
