The Panvitalistic Theory (PVT) posits volume as ontologically primary, measurement as rational comparison of two real 6D volumes (VA = xVB, x ∈ Q), time T as angular curvature (π ≡ 1 s/m or 1/12 s/m), and primary velocity as areal c = L^2/T emergent from Earth’s rotation.Special relativity implicitly assumes isotropic 3D space with a priori orthogonal axes (all angles 90°), forcing c to be a universal linear constant L/T. General relativity must then introduce spacetime curvature to compensate for the consequences of this unmotivated isotropy postulate. PVT demonstrates that no such isotropy is required or justified: space is 6D with variable angles, and 90° is merely the calibration maximum of effective density. Gravitational and relativistic effects emerge as projections of angular deviation from orthogonality – without Lorentz transformations, without universal c = L/T, and without curvature as a fundamental entity. The theory reproduces the GPS clock correction (≈ +38.7 µs/day net) with high accuracy using a single geometric mechanism. It offers a radically more parsimonious ontology that resolves the quantum-gravity incompatibility at the level of foundational assumptions and explains cosmological anomalies (dark matter, dark energy) as artifacts of extrapolating an Earth-calibrated framework.
