We present Chronon Field Theory (CFT), a covariant framework in which large–scale spacetime geometry—including temporal order and causal structure—emerges from the coarse–grained dynamics of a single future–directed timelike field Φμ(x). Within this approach, both the unit–norm property of Φμ and the Lorentzian signature of gμν are not postulated but arise uniquely from random microscopic chronon dynamics under broad symmetry and locality assumptions. Quantum phenomena are reinterpreted in this geometric setting: double–slit interference results from phase–coherent Φ–threads rather than superposed particle paths, and measurement appears as a boundary–induced alignment of microscopic orientations with the apparatus’s macroscopic field, yielding definite outcomes without collapse or branching. Schrödinger’s cat is then a straightforward macro–micro coupling with no persistent macroscopic superposition, while EPR–type entanglement reflects shared Φ–thread ancestry across spacelike separations. The Born rule follows from the unbiased martingale structure of alignment dynamics and from coarse–graining symmetries, making it an emergent statistical law; the uncertainty principle appears as a statistical bound on chronon fluctuations, with ℏ arising as the variance of coarse–grained action. CFT thus provides a covariant and ontologically economical framework linking spacetime symmetries to quantum measurement, and predicts scale–dependent effects—such as nonlinear decoherence and curvature–sensitive timing shifts—that are open to experimental test.
