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

m_J = 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.
