Geometric Origin of Dark Components: A Causal-Asymmetry Hypothesis

Year: 2026
Type: article
Abstract: This working draft refines the author's hypothesis that the apparent components of the cosmological energy budget — dark matter and dark energy — emerge as geometric and causal-asymmetry effects of the Hubble, event, and particle horizons, with ordinary baryonic matter as the only physically real source. Under Planck 2018 parameters, numerical verification has produced a striking quantitative result for the dark-energy sector: the inward gravitational acceleration produced at the event horizon by the baryonic mass enclosed in the donut-shaped shell between R_EH and R_PH matches the Friedmann acceleration H_0² (Ω_Λ − Ω_m/2) R_EH to within 0.1% accuracy, with no need for a cosmological constant or a negative-pressure vacuum field. This result is the hypothesis's strongest verified claim. In contrast, the proposed account of dark matter — based on the volume ratio between the Hubble interior and the R_H–R_EH shell — has been found to be highly sensitive to the precise value of R_EH, with the agreement varying from 20% (for R_EH ≈ 16.0 Gly) to 60% error (for R_EH ≈ 16.7 Gly, the precise ΛCDM integration). The original v0.1 reasoning — that this volume ratio coincidence, combined with cosmic homogeneity, suggests a redshift-to-baryon conversion mechanism between the Hubble and event horizons — is preserved as the conceptual motivation, but the precise mechanism is acknowledged as incomplete. The Rindler universe construction (introduced in v0.2 as a refinement of the Hubble radius) remains under development. The work is offered for priority recording and as a basis for further analytical and computational work.
