The Cosmological Constant as CPT Projection Tension
Year: 2025
Type: article
Abstract: We derive the observed value of the cosmological constant from golden theoretical first principles using the projection-based framework of emergent, golden ratio-selected spacetime. In this model, the physical reality we observe arises as a bidirectional projection from a static, timeless, fully symmetric and scale-invariant conformal boundary. The observed late-time acceleration of the universe is shown to result from a small but finite asymmetry in projection curvature at the symmetry midpoint. We compute the projection tension arising from this CPT-symmetric bidirectional unfolding and show that it naturally yields Lambda ≈ 1e-122 in Planck units, consistent with observation and without invoking vacuum energy, fine-tuning, or scalar fields.
