Zenodo Upload Description Title: The Orthogonal Emergence of Time, Inertia, and Gravity within General Expanse Tension Theory (GETT)Version: 2.3 (2025)Author: John — Independent Researcher, Expanse Tension Theory Full Description This paper introduces a new physical principle—Orthogonal Emergence—demonstrating that gravity, inertia, and the flow of time are not fundamental or independent phenomena but instead arise as three mutually orthogonal projections of a single scalar field, Φ, whose tension activates only when mass is licensed by the Higgs field. Working within the General Expanse Tension Theory (GETT) framework, this paper shows that the effective action for a mass–Φ configuration decomposes cleanly into three independent response modes: RvR_vRv — resistance to motion (inertia) ReR_eRe — resistance to expansion-driven separation (gravity) RτR_\tauRτ — resistance to temporal separation (proper time / temporal flow) A variational analysis reveals that these responses arise from the diagonal structure of the Hessian of the action, guaranteeing mathematically and physically that the three modes are orthogonal, independent, and experimentally separable. Despite this orthogonality, their magnitudes co-vary because all three depend on the same underlying Φ-tension state, which itself depends on local density and expansion coupling. A complete environmental mapping is presented, dividing the cosmos into ten regimes (Appendices A–J) ranging from terrestrial densities to neutron stars, galactic cores, outer halos, deep cosmic voids, globular clusters, the pre-mass early universe, and the interior of black holes. Each environment is represented in the three-axis Φ-response space, revealing a unified explanation for: classical Newtonian/GR gravity, anomalous galaxy rotation, void lensing and bulk flows, the Hubble tension, neutron-star behaviour and glitch phenomena, rapid early-universe evolution, black hole interiors (Higgs restoration → Φ de-emergence), and ultra-low-density bright-void behaviour. The paper also places orthogonal emergence in context with 2025 contemporary emergent-gravity frameworks, including Inertio-Spin Emergent Gravity, vector-geometry models, and quantum-coherence substrate theories, highlighting GETT’s advantages: single-field parsimony, density-triggered behaviour, Higgs-activation unification, and a direct physical origin for time dilation. A dedicated section addresses early-universe implications, showing that before the Higgs acquired a non-zero vacuum expectation value, the universe possessed no mass, no Φ-tension, no gravity, no inertia, and no proper time. Inflation therefore occurred outside of time. Once mass formed, Φ-tension activated, giving rise to the first clocks—implying that early cosmic epochs progressed under extreme temporal resistance, meaning that the “microseconds” and “minutes” of early-universe cosmology correspond to vastly longer durations relative to present-day Earth clocks. Finally, the paper presents a set of testable predictions, identifying observational signatures across galaxy outskirts, deep voids, globular clusters, and precision time-dilation environments. A comparison table clarifies how GETT’s orthogonal emergence differs from and improves upon all existing emergent-gravity paradigms, while remaining consistent with Higgs physics and established symmetries.
