What Does the Universe Look Like? A New Dark Matter Candidate from the Ouroboros Lagrangian

The nature of dark matter remains unknown after decades of searches for WIMPs and axions. We present the neutral chaoiton – a stable, oscillatory, localized solution of the Ouroboros Lagrangian, a classical field theory that is dynamically equivalent to a superrenormalizable bosonic quantum field theory (Werbos 2026, Zenodo 20330894). The theory has only three free parameters and requires no renormalization subtractions. The neutral chaoiton carries no electromagnetic charge, interacts with ordinary matter only via a massive vector field (the J‑field), and has mass m_χ = 0. 460 MeV, mediator mass mJ = 0. 618 MeV, and coupling C = 770 MeV·fm – all derived from the same parameters that fit the electron. Its self‑interaction is mediated by a Yukawa potential, yielding a momentum‑transfer cross‑section σ/m_χ ∼ 0. 1–1 cm²/g – consistent with Bullet Cluster bounds and testable by future galaxy cluster observations (e. g. , LSST). We show that this cross‑section naturally produces halo cores in low‑surface‑brightness galaxies and suppresses small‑scale structure, alleviating the “missing satellites” problem. A layered nanostructure sensor network can detect the galactic dark matter wind via coherent J‑field disturbances. Crucially, when the Ouroboros Lagrangian is coupled to gravity in Moshe Carmeli’s five‑dimensional gauge formulation (‘Cosmological General Relativity’), the combined system becomes a complete, finite, superrenormalizable theory of all known interactions – gravity included, with no free parameters beyond those already calibrated. The neutral chaoiton is therefore a falsifiable, observationally accessible dark matter candidate emerging from a unified, first‑principles field theory, independent of the WIMP miracle or axion fine‑tuning.
