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

Gravitational lensing has revealed a universe filled with invisible mass.
From the Bullet Cluster to JWST's deepest maps, the evidence for dark matter
is overwhelming—yet its nature remains unknown.  WIMP searches have come up
empty, axion haloscopes report null results, and recent discoveries of
galaxies apparently devoid of dark matter challenge the standard cold dark
matter paradigm.  This paper presents the neutral chaoiton of the Ouroboros
Lagrangian—a classical field theory with only three free parameters that is
dynamically equivalent to its own canonical quantization—as a natural dark
matter candidate.  We show that the massive J-field of the theory subsumes
the axion via the dual axion mechanism of Brennan (2024): the axion is the
longitudinal mode of the J-field.  The neutral chaoiton mass is set by the
same parameters that fit the electron and the long-range nuclear force,
requiring no new inputs.  A preliminary freeze-out estimate gives a relic
abundance Ω_c h² ≈ 0.1–0.2, consistent with the Planck value once the
neutral-chaoiton ground-state mass is determined.  The model survives all
existing axion experimental bounds (ADMX, CAST, beam-dump, stellar cooling)
with only mild cosmological tension—a falsifiable prediction for future CMB
and BBN data.  We propose a layered nanostructure sensor network to detect
the galactic dark-matter wind through coherent J-field disturbances.
