The Bullet Cluster's 720 kiloparsec peak-to-peak separation between lensing mass and X-ray gas is the canonical proof of collisionless dark matter, yet the exhibit audits poorly: the system's infall velocity sits in the improbable tail of ΛCDM kinematics, Abell 520 shows a dark core where lensing mass sits with the gas and without galaxies, and offset distributions now squeeze the self-interacting variants invoked for the model's small-scale problems. The icon constrains its owner.
The model reads every offset through one lens: a collisionless particle fluid that must track the galaxies everywhere, with no second mechanism available. Conforming systems confirm the particle; anomalous ones, dark cores, strained timings, forbidden velocities, must be argued away case by case, because the particle cannot do anything else.
SCT passes the Bullet's actual test structurally: the amplified gravitating component is the coherent superposition of the comoving galaxy ensemble (P50, P52, P53), collisionless by nature since coherence is a phase relationship, not a fluid, so the effective mass rides ahead with the galaxies while the shocked, decohered gas lags. Galaxy-coincident lensing offsets are the automatic output, no particle required, and the offset's celebrated geometry discriminates in SCT's favor against any account tying gravity to the dominant baryonic gas. The mechanism is a coherence-length separation: the collisionless galaxies stay phase-organized and retain the virialized amplification A = A* = 6.173, while Coulomb scattering collapses the collisional gas's correlation length to the ion mean free path and drops it to the cosmological floor A_gas = 1 + R_b/3 = 1.085 (R_b = 0.2545, the SCT effective baryon-loading parameter), a contrast of ~5.69. Evaluating the effective lensing mass at each peak within the 250 kpc aperture (Paraficz et al. 2016) gives a 3.36 factor centroid dominance on the galaxies, reproducing the offset with canonical baryons and no free parameters.
The anomaly file reads naturally in coherence terms: encounter velocities come from cascade kinematics (the El Gordo entry's physics), so the Bullet's improbable speed is expected output, and configurations like Abell 520's dark core, coherence lingering where an ensemble decohered or overlapped, are available states of a phase-structured mass component, though their quantitative reconstruction belongs to a full coherence-field treatment.
This is the same coherence-rides-the-galaxies structure behind the two-mass SZ resolution and the DF2 decoherence. The exhibit's geometry was never the particle's private property.
DEMONSTRATED (offset) + CONDITIONAL (total mass): the offset geometry follows from coherence-length separation, and the quantitative offset is reproduced as a 3.36 factor centroid dominance with canonical baryons and zero free parameters. Total lensing mass closes to 81.5% on a canonical IMF and fully under a 1.27x stellar-remnant (IGIMF) correction (Zhang et al. 2026); that residual is the conditional element.
This resolution is developed in Paper 12, From Chaos to Coherent Gravity, with the underlying mechanism in Paper 11, From Chaos to Cosmic Collisions.
The falsifier is quantitative: a resolved strong-lensing decomposition placing the lensing centroid on the gas rather than the galaxies, or an effective-mass dominance at the galaxy peak below the observed centroid separation, falsifies the coherence-length reading. Population-level, offset catalogs statistically demanding a particle fluid with nonzero self-interaction, distributions incompatible with phase-coherent galaxy-riding mass, would break the ensemble reading.
