Native Cosmic Acceleration and Inflationary Wavefronts: Eliminating Lambda and Scalar Inflaton Fields

Standard ΛCDM cosmology splits the early and late expansion of the universe into two distinct, un-unified phenomena: an early inflationary epoch driven by a temporary, hypothetical scalar "inflaton" field, and late-stage cosmic acceleration driven by Dark Energy (Λ). This division leads to the Cosmological Constant Problem—failing to predict vacuum energy density by up to 120 orders of magnitude—and introduces severe fine-tuning crises. This paper presents a deterministic, unified resolution to the expanding universe paradoxes by applying the 13 Master Field Equations of The Unified Theory of Absolute Spatial-Temporal Geometric Tension. By treating the cosmos as a continuous fabric regulated by a dynamic space tension field (W) and a bounded elastic potential (V(W)), I show that cosmic expansion is a native consequence of macroscopic wave mechanics. In the early universe, extreme cosmic compression drives the tension field to its absolute ceiling (W → W_max), triggering a massive potential spike (Master Eq. 3) that propagates as an outward structural shockwave (Master Eq. 4), natively executing exponential inflation. Conversely, late-stage acceleration emerges as a residual, asymptotic elastic relaxation of the vacuum fabric across vast spatial scales (s → ∞) governed by the fabric strain filter (Master Eq. 7). Finally, I demonstrate that the emergent nature of the effective Planck constant (ℏ_eff, Master Eq. 9) naturally absorbs the modern expansion rate discrepancy known as the Hubble Tension as a native spatial scaling artifact.
