Particle Colliders and the Search for Fundamental Constituents: What QGD Implies for High-Energy Physics

The construction of particle colliders rests on two assumptions: that higher collision energies reveal more fundamental structure, and that sufficiently energetic collisions reproduce the conditions of the early universe shortly after the Big Bang, granting experimental access to the primordial constituents of matter. This paper examines both assumptions from the perspective of Quantum-Geometry Dynamics (QGD), a framework derived from three axioms and two constants in which space is constituted by a finite discrete structure of fundamental spatial units called preons (−), matter is constituted by preons (+) propagating by directed leaps, and two forces govern all interactions: p-gravity, attractive between all preons (+) regardless of separation and distance-independent in strength, and n-gravity, repulsive between preons (−) with magnitude increasing with separation and dominating beyond the threshold distance d_Λ. The QGD gravitational force is given explicitly: F⁺ (a, b) = k · n (p⁺ₐ) · n (p⁺b) for the attractive component and F⁻ (a, b) = k · n (p⁻ₐ) · n (p⁻b) / d² for the repulsive component. A critical scale fact governs the entire analysis: all nuclear and sub-nuclear physics occurs at separations orders of magnitude below d_Λ, where n-gravity is entirely negligible and the force competing with p-gravity is electromagnetic repulsion between charged aggregates. Both justifications for collider physics fail in the QGD framework. The early-universe justification fails because the initial state of the universe in QGD was not a hot dense singularity but a cold, uniform, isotropic distribution of free preons (+) propagating through the discrete preonic structure of space with constant intrinsic momentum c̃. This initial state is not a postulate but the unique state consistent with the three axioms in the absence of any prior causal history. Since there was no Big Bang, high-energy collisions reproduce nothing about the initial universe: they reproduce the extreme local disruption of p-gravity bound configurations at sub-nuclear scales, followed by immediate re-binding driven by p-gravity against electromagnetic repulsion. The constituents-at-higher-energies justification fails for two independent reasons. First and most fundamentally, the law of momentum transfer established in the QGD book imposes a minimum permissible momentum change on an electron below which no interaction can produce a detectable response. A single free preon (+) carries momentum c̃. If c̃ falls below this minimum, free preons (+) are physically undetectable in principle — not as a practical limitation of detector sensitivity but as a fundamental physical constraint derivable from the QGD axioms, independent of detector design or collision energy. This argument generalises: any preonic aggregate whose resultant momentum |P⃗| falls below this threshold is undetectable regardless of experimental setup. This provides the QGD account of dark matter — preonic aggregates that are gravitationally active (p-gravity couples to preon (+) count, not to |P⃗|) but electromagnetically invisible because they cannot produce the minimum permissible electron momentum change. Second, p-gravity immediately re-binds any freed preon (+) against electromagnetic repulsion before it can propagate to a detector, since the collision occurs at scales orders of magnitude below d_Λ where p-gravity acts at full constant strength. In QGD, particles produced in colliders are not created from the vacuum and are not quark-gluon recombination products. They are the stable attractor configurations of the p-gravity re-binding cascade operating on freed preons (+) and sub-aggregates in the aftermath of the proximity event, with total preon (+) count and total momentum conserved throughout. The specific particle types that appear repeatedly are those stable p-gravity equilibrium configurations for which p-gravity overcomes electromagnetic repulsion at the relevant sub-nuclear separations. Resonances are metastable configurations in which p-gravity only marginally overcomes electromagnetic repulsion. There are no quarks, no gluons, and no colour charge. Confinement arises from two independent physical reasons: p-gravity drives immediate re-binding subject to overcoming electromagnetic repulsion, and freed preons (+) fall below the minimum permissible momentum change of an electron. N-gravity plays no role at nuclear scales. The paper further addresses particle creation and antimatter. Total preon (+) count is conserved in all interactions: apparent particle creation is rearrangement of pre-existing preons (+). Antimatter in QGD is a preonic aggregate whose internal p-gravity configuration is the mirror image of the corresponding particle. Matter-antimatter asymmetry is a consequence of the initial preonic composition of the universe rather than a production asymmetry requiring CP violation. The mass hierarchy of elementary particles reflects a hierarchy of preon (+) counts: mass equals n (p⁺) times the preonic mass unit m̃, with no Higgs field required. The strategic implication is direct. Increasing collision energy does not grant access to more fundamental structure in QGD. The fundamental constituents are accessible through the empirical grounding programme of Addendum F of the QGD book, which derives the constants c̃ and k from independent non-cosmological measurements. Once the preonic mass unit m̃ is determined, the preon (+) count of every known particle follows from its measured mass, and the entire particle spectrum becomes a structural classification problem derivable from the three axioms and two constants. The question that advances fundamental physics is not what new particles lie at higher energies but what are the values of c̃ and k.
