From Phase to Spacetime

From Phase to Spacetime (Phase Ontology — Part II) develops the central consequence of Part I (Phase Without Ontology): if phase coherence is treated as an ontologically primary layer, then spacetime cannot be fundamental. This paper proposes a conceptual pathway by which temporal order, spatial geometry, and gravitational effects can be understood as emergent structures arising from stable phase relations—without introducing new dynamics or speculative entities. The core move is operational: clocks are oscillators, and what we call “time” is the comparison and synchronization of counted cycles across systems. Temporal order appears where phase relations are stable; divergence in clock rates appears where coherence conditions vary. In this framework, proper time corresponds to a system’s internal phase evolution, and relativistic phenomena (time dilation, gravitational redshift) are reinterpreted as changes in phase evolution induced by coherence gradients. Spatial distance and geometry are treated as doubly derivative: they are inferred through timing relations, synchronization procedures, and stable relational structure across extended systems. Uniform coherence yields an effectively “flat” geometry; varying coherence yields curvature-like behavior. The paper also sketches how inertia and acceleration can be viewed as resistance to reconfiguring phase-locked relations, aligning naturally with the equivalence principle. This work is Part II of a seven-part series that reframes foundational problems—unification, measurement, nonlocality, and the status of time—through the lens of phase coherence. Part III addresses measurement and classical definiteness; Part VII discusses experimental implications and falsifiability.
