Where Is Antimatter? It Is Inside All of Us - A Gauss–Riemann–OUXSPACE Conjugate-Closure Model

For decades physicists have asked: Where is antimatter? Why does the accessible world appear so strongly asymmetric, with ordinary macroscopic environments overwhelmingly matter-dominated—schematically more than 99.99% matter in everyday samples—while freely observable antimatter is sparse and is usually encountered in rare natural events or created in energetic particle processes? The numerical phrase above is used only as an intuitive description of present-day accessible matter and is not a precision statement of the cosmological baryon-asymmetry parameter. This paper proposes a Gauss–Riemann–OUXSPACE model in which the apparent imbalance is interpreted as a projection/readout asymmetry rather than a fundamental absence of antimatter. In the proposed construction, an electron-labelled manifestation is not a primitive point object. It is the visible 3D readout of a higher-dimensional cap–cylinder–cap closure configuration. The visible electron scale is taken as the reduced Compton radial scale R_e = λ_C,e/(2π), while a higher-dimensional cylindrical closure extension obeys the model relation L_e/R_e ≈ α¹. Numerically this gives L_e ≈ 5.29177×10¹¹ m ≈ 52.92 pm. The opposite cap is assigned the ⁻⁻conjugate Gauss-readout sign and is interpreted as the positron-labelled manifestation. Electric field lines that appear to begin or end in one 3D projection are hypothesized to close through the higher-dimensional bridge onto the conjugate cap. For the proton/antiproton branch the geometry is not assumed to be a scaled copy of the electron branch; instead it is modeled as a more compact multi-channel cap/throat closure. The OUXSPACE branch comparator ρ_ep = δ_e/δ_p ≈ 1836.152673426 gives, under the direct identification δ_e = L_e, a proton/antiproton interlayer scale δ_p ≈ 2.882×10¹⁴ m ≈ 28.82 fm, i.e. an order-30-fm scale. Values near 30–33 fm require an ⁻explicitly stated proton-branch correction if used. The central hypothesis is that matter and antimatter are not different underlying substances in this model, but conjugate projection states of the same closure architecture, distinguished by opposite internal orientation. The opposite electric-charge sign is treated as the observable Gauss readout of that conjugacy. A π-orientation inversion changes the readout sign while preserving the parent energy scale; for the electron the natural rest-energy comparator is m_e c² ≈ 511 keV, whereas creation of a free ee pair ⁻⁺requires at least 2m_e c² ≈ 1.022 MeV. Annihilation is interpreted as loss of separate conjugate readouts and release of the stored closure energy into ordinary observable channels. The paper develops the geometric skeleton, Gauss-flux relations, projection maps, branch compactness relations, energy and magnetic readout skeletons, and falsifiable consequences of this hypothesis.
