The Unnecessary Dimension: Why Physical Time Fails Every Available Test, and What Causal Succession Replaces It With

Physical time is assumed on both sides of the debate over its reality: proponents treat relativity's confirmed predictions as settling the question, and most opponents who deny time's fundamentality still treat that denial as a further hypothesis requiring independent proof rather than a default position requiring none. This paper argues that neither posture is warranted, because four independent lines of argument, none dependent on the others, jointly leave physical time without a single remaining ground of support — and closes by showing the resulting framework still answers every practical demand a physical theory must meet, including predicting motion and measuring distance, without reintroducing time to do it. First, the claim that describing physical change requires time — that speed, momentum, and energy cannot be defined without it — is false: Quantum-Geometry Dynamics (QGD) defines each as an intrinsic, time-free property of preonic structure, derived from just two axioms (space as discrete preons⁻, matter as discrete kinetic preons⁺), showing that time is not needed to describe reality and therefore has no claim on reality that description could establish. Second, the intuition that clocks measure time conflates measurement with counting: a clock counts recurrences of a periodic, causally-linked internal state, and no experiment in the history of physics has measured anything beyond that count. Third, the one phenomenon relativity's defenders could point to as requiring physical time — the confirmed slowing of clock rates with velocity and gravitational potential — is reproduced by QGD to the same quantitative precision from a fixed, time-free momentum budget, leaving no observation that only a physical-time hypothesis explains. A direct experimental candidate for counter-evidence, the BaBar collaboration's 2012 observation of time-reversal violation in the neutral B-meson system, is addressed directly and shown to confirm the paper's account of categorical, mechanism-level irreversibility rather than undermine it. Fourth, every major framework in physics, and every serious philosophical account of temporal passage, imports physical time as a precondition of its own construction rather than deriving it — an insulation failure at the conceptual level that the Axiomatic Imperative rules out before a single equation is written. What survives this fourfold elimination is causal succession: the unique determination of successor preonic states by prior states under QGD's two axioms, sufficient on its own to account for temporal ordering, temporal direction, and the phenomenology of experienced passage. Categorical, mechanism-level irreversibility — compatible with, and sharply distinguished from, the eventual recurrence of generic states guaranteed in a finite deterministic system — supplies the direction causal succession would otherwise lack. The paper closes with three further results, the last new to this version. It answers the practical demand to predict how far a moving object travels in a given duration without a time variable, by defining duration itself as a distance — the leap-count of a reference particle — so that the prediction reduces to a ratio between two distances. Two theorem-level consequences follow: because causal succession advances the universe's entire state matrix in lockstep under universal, instantaneous gravity, the universe itself functions as a single universal clock, and because quantum-geometrical space is a fixed, observer-independent structure, QGD recovers a Newton-style absolute space and a universal state-count standing in for absolute time — not as unexplained primitives, but as theorems following from the two axioms. New in this version, §8. 6. 1 closes a companion gap the leap-count construction leaves open: because that construction still measures distance against a chosen reference particle's leap-count, a critic could ask whether distance, like time, is being smuggled back in as a matter of convention. It is not, and the paper now shows this directly — distance is separately recoverable from the gravity equation alone, with no reference object of any kind. For two particles of known mass, resolving QGD's equation for gravity, G (a;b) = mₐ·mb· (k − (d²+d) /2), for d given a single measured interaction yields a closed-form, absolute distance in native preonic units. Seven standard objections are now engaged directly: relativity of simultaneity, quantum mechanics' external time parameter, the charge that this merely restates eternalism, the felt experience of passage, direct experimental evidence of time-reversal violation, the distance-prediction demand, and — new in this version — the reference-convention worry about distance itself.
