The 11 Mechanisms

The 231 catalogued ΛCDM tensions are not 231 unrelated problems requiring 231 separate fixes. They cluster into 11 Primary Causal Generators (PCGs), labelled M1–M11 — each a single physical mechanism in SCT that resolves an entire class of tensions. The keystone mechanism for any tension is the one whose removal would collapse the explanation. Each mechanism is grounded in numbered premises (P1–P69).

When two comoving structures with relative velocity v_rel > c intersect, the intersection front propagates through each pocket faster than any internal signal can travel; the overlap volume is engulfed before any internal communication can warn the interior. Pre-existing matter is thermalized into a hot dense plasma — locally, in the overlap volume only. Outside the collision region the parent pockets continue to exist as the large-scale structure that embeds our observable patch.
The collision deposits the full kinetic energy of both pockets into the overlap volume essentially simultaneously. For a pocket of mass M ≈ 10⁵³ kg colliding at v_rel ~ 10c, the kinetic energy corresponds to temperatures reaching the QCD scale (T_QCD ≈ 1.7 × 10¹² K) and potentially the electroweak scale in compressed hotspots — the same physical regime as heavy-ion collisions at CERN and RHIC, at vastly larger scales. No new physics is introduced and no energy condition is violated: the driving energy is real classical kinetic energy in the bulk motion of massive pockets. Phase-velocity propagation of heating can exceed c without violating causality, because information transport (group velocity) is always ≤ c.
Cosmogenesis itself; the horizon problem (the entire overlap thermalizes simultaneously); the flatness problem (virial theorem on the collision remnant); CMB homogeneity without super-Hubble inflation; the origin of pre-existing matter (recycled from prior collision generations); and "what came before the Big Bang" (an eternal infinite manifold).

Once a photon-baryon plasma thermalizes, its subsequent acoustic behaviour is determined entirely by its thermodynamic state at decoupling — temperature, density, baryon-to-photon ratio, and the perturbation spectrum. The plasma has no memory of whether it was created by a singular origin or by a cascade of superluminal collisions. Two plasmas arriving at the same thermodynamic state by different paths produce acoustically identical CMB power spectra at multipoles ℓ > 30.
The one categorical exception to this erasure is angular momentum: a conserved vector quantity protected by Noether's theorem, it cannot be destroyed by thermalization, only redistributed. The collision history is erased from the CMB scalar spectrum but written into the rotation of every structure that forms from the post-collision plasma. Three independent constraints (BBN abundances, COBE/FIRAS spectral purity, Planck acoustic-peak positions) place cascade termination before t ≈ 1 second; after that the universe evolves under standard physics.
Why SCT's collision-origin plasma produces a CMB indistinguishable from ΛCDM at small angular scales; why BBN abundances are reproduced exactly; and how recombination-epoch heterogeneities (CMB Cold Spot, hemispherical asymmetry) arise from collision-cascade thermalization heterogeneity at large angular scales.

When two pockets collide with non-zero impact parameter b, angular momentum J = μ(b × v_rel) is deposited into the overlap volume. The inherited specific angular momentum j = J/M sets the centrifugal barrier for gravitational collapse, and a centrifugal barrier in a self-gravitating system produces an isothermal density profile ρ(r) ∝ r⁻² — precisely the profile that generates flat rotation curves without a dark matter particle.
Angular momentum conservation operates simultaneously at every level of the nested hierarchy. Structures that condense from rotating material at the scale above inherit a fraction of the parent's angular momentum proportional to their mass fraction and position, producing the observed J ∝ M^(5/3) scaling across seven decades of scale, from planetary systems to supercluster complexes.
Flat galactic rotation curves; the J ∝ M^(5/3) scaling; co-rotating satellite-plane alignments around MW, M31, Cen A and others (joint ΛCDM probability ~2 × 10⁻¹⁴); cluster rotation velocities (~360 km/s at 10¹⁴ M☉ rising to ~693 km/s at 10¹⁵ M☉, Tang et al. 2025); individual filament bulk rotation (Tudorache et al. 2025); BCG-cluster shape alignment already in place at z > 2.

The full cosmic web emerges from the parameter space of collision geometries. Grazing collisions (more probable, since P(b) ∝ b) produce rotating halos with inherited J. Near-head-on collisions convert kinetic energy into heat and axial compression, producing elongated high-density filaments. Collision nodes — where filaments of different orientations intersect — produce the most massive clusters.
The scale distribution mirrors the scale-invariant hierarchy: grandparent-scale collisions produce gigaparsec superfilaments, parent-scale collisions produce 100-Mpc filaments, sibling-scale collisions produce 10–50 Mpc structures. The first collision stage produces ring-and-filament structures at the scale of the colliding pockets, characteristic Λ_max ≈ 2 × R_pocket ≈ 5 Gpc.
Filament/wall/void morphology without dark matter potential wells to seed it; gigaparsec anomalous structures (the Big Ring at 1.3 Gly, the Giant Arc at 3.3 Gly, the Hercules–Corona Borealis Great Wall); the KBC supervoid scale; the supervoid abundance excess (~5× ΛCDM); filament vorticity excess; and cosmological-principle violations at the largest scales (predicted in SCT, not anomalous).

No orbit in any gravitational system is perfectly stable across infinite time. Three-body interactions eject lighter objects outward while dynamical friction concentrates massive objects inward, progressively weakening the overlapping network of gravitational potential wells — the gravitational mesh — that all objects in a frame collectively contribute to. An embedded observer using locally calibrated instruments cannot detect a uniform change in their own clock rate, but they can detect a frequency shift in light from distant sources, which they model as recession velocity and therefore as expansion of space.
The cosmological constant becomes a dynamical, environment-dependent ratio Λ_eff(x,t) = κ × [U_local(x,t) / U_parent(x,t)], with κ calibrated to reproduce the observed Λ_obs ≈ 1.1 × 10⁻⁵² m⁻² when spatially averaged. In overdense regions Λ_eff is suppressed; in voids it is enhanced, producing a spatially varying expansion rate at the ~1% level on 100–300 Mpc scales. We sit inside the KBC supervoid (~20% underdensity within 300 Mpc), so the local distance ladder (H₀ = 73.0) samples the void-enhanced rate while the CMB (H₀ = 67.4) samples the global average: a KBC contribution (~2–3 km/s/Mpc) plus temporal evolution of Λ_eff since recombination (~2–3 km/s/Mpc).
The Hubble tension; the ~10¹²⁰ cosmological-constant fine-tuning problem; the coincidence problem; the DESI 2024 evolving-w(z) hints (a geometric artifact of forcing inhomogeneous Λ_eff into a homogeneous parameterization); the S₈ tension; environment-dependent BAO scale shifts; and the A_lens = 1.18 anomaly.

At recombination the photon-baryon fluid is governed by a sound speed that depends on the baryon loading. In SCT's Coherent Acoustic Resonance framework, c_s² = (1 + R_b) / 3, where R_b is a fixed geometric baryon-to-photon coupling parameter derived from cascade geometry. Paper 15 fixes R_b = 0.260 ± 0.002 phenomenologically; the cascade model derives R_b = 0.2545 ± 0.032 from first principles (SO(3) cascade mode count plus QCD-boundary and photon-heating corrections), agreeing with observation at 0.17σ — a test, not a fit.
This raises the sound speed to c_s² ≈ 0.42 c² and shifts the BAO drag radius to r_d ≈ 146–149 Mpc, versus ΛCDM's ~150 Mpc and the DESI-DR2 measurement of ~147 ± 1 Mpc, reducing the inter-dataset tension from 2.3σ to ~1.1σ. The framework also derives a coherence floor Ĉ_bg = 1 + R_b/3 ≈ 1.0848 with zero free parameters, predicting S₈ = 0.783 ± 0.015 and resolving the S₈ tension with ΔBIC = −411 versus ΛCDM.

The domain specifier [0.08 fm ≤ r] declares the lower boundary of GR's domain of validity. At densities above ~5–10 times nuclear saturation density, the Fermi degeneracy pressure P_deg ~ (ℏc/4)(3π²)^(1/3) n_q^(4/3) grows faster than gravitational pressure for sufficiently stiff equations of state, preventing singularity formation. At the centres of black holes SCT predicts stable compact polyquark states rather than singularities. The Schwarzschild exterior is preserved for r > 2GM/c², so lensing, mergers, and accretion match standard GR; only the interior is bounded.
Direct TOV integration of the QCD-compatible EOS band yields a maximum stable compactness C_max ∈ [0.244, 0.347], below the Buchdahl limit 4/9, with finite density and pressure and bounded curvature throughout. The mass-radius band spans M_max ~ (2.0 ± 0.5) M☉ and R ~ 10 ± 2 km, consistent with NICER's PSR J0740+6620 (M = 2.08 ± 0.07 M☉) and the GW170817 tidal-deformability bound.
The singularity problem in GR (singularities signal a model applied outside its domain, not a physical prediction); the 2-solar-mass neutron-star existence; the soft-edge tidal-deformability constraints from GW170817; and the stiff-edge radius tension with NICER. Predictive distinction: gravitational-wave post-merger echoes at delay τ ∝ M_BH with a modified quasi-normal-mode spectrum, detectable by Einstein Telescope and LIGO-Voyager.

SCT satisfies all three Sakharov conditions using only Standard Model physics, enhanced by the extreme non-equilibrium environment of the collision. Baryon-number violation: sphaleron processes, exponentially enhanced in the non-equilibrium shock environment, provide it at a rate far above the equilibrium value. CP violation: the angular-momentum vector J = μ(b × v_rel) defines a preferred spatial axis that distinguishes left from right in the collision plane, a geometric CP-violating term of effective magnitude δ_CP,eff ≈ 10⁻² to 10⁻³ versus the CKM value ~10⁻²⁰ — amplification by 17–18 orders of magnitude. Departure from equilibrium is built into the cascade structure.
Output: η_B ≈ 6 × 10⁻¹⁰, matching the Planck 2018 value (6.097 × 10⁻¹⁰ ± 0.019 × 10⁻¹⁰).
The baryon asymmetry of the universe without any beyond-Standard-Model physics: no leptogenesis, no GUT-scale CP violation, no axion, no supersymmetric flavour structure. The Standard Model is sufficient given the geometric amplification.

Material outside the primary collision overlap volume also receives momentum kicks from the propagating shock and fragments into daughter clumps under the collision's angular momentum. The probability that the collision was precisely head-on enough to produce only our pocket is ~0.25%; the generic outcome is a system of multiple sibling pockets sharing the same J vector.
Sibling pockets share our parent comoving frame because momentum conservation in the cascade leaves all daughter fragments comoving at the grandparent level. For typical separations of 1–2 Gpc the nearest sibling recedes at ~0.23c–0.47c — subluminal, within our Hubble sphere, and in principle detectable through its gravitational influence. Siblings also share our Λ_eff variation, so temporal changes in parent-frame mesh dissipation produce correlated expansion-rate variations across gigaparsec scales.
Large-scale bulk flows (CosmicFlows-4: 400–600 km/s toward Centaurus–Vela, ~2× ΛCDM); CMB large-angle anomalies (quadrupole suppression ~0.25, octupole-dipole alignment); correlated expansion-rate variations at gigaparsec scales; the El Gordo cluster collision speed (improbable at <10⁻⁹ in ΛCDM).

The geometry of the primary collision — direction of impact, tilt, rotational orientation — leaves long-lasting observational imprints on cosmic structure. The collision angular-momentum vector J = μ(b × v_rel) defines a preferred spatial axis. The CMB dipole direction is predicted to be approximately perpendicular to the large-scale angular-momentum coherence axis, since the frame velocity is parallel to the impact parameter b, which is perpendicular to J.
Hemispherical CMB power asymmetry (~7%), quadrupole-octupole alignment, odd-parity preference, and the CMB Cold Spot all share the same preferred axis. Future high-sensitivity CMB polarization maps should show a correlated polarization anomaly co-located with the Cold Spot.
The CMB Axis-of-Evil (2.8σ); hemispherical power asymmetry (2.5σ); the CMB Cold Spot (3σ, ~70 µK deficit); odd-parity preference; quasar polarization coherence at 1 Gpc (Hutsemékers; Mandarakas et al. VLBI at >99.5%); large-scale parameter dipoles (Migkas et al. 2021, ~3σ).
The collision did not create matter from nothing. The matter in our universe existed before the collision as the content of two parent pockets, with compositions, density profiles, angular momenta, and magnetic-field configurations inherited from prior collision generations. The collision thermalized pre-existing matter; it did not create it. Matter dispersed by collision events is recycled into new collision fuel through gravitational re-concentration over timescales of order 10¹⁰⁰ years or more — and in an infinite, eternal universe that timescale is irrelevant. Initial conditions (pre-existing metals, magnetic seed fields, compositional patterns) are derived quantities from prior cycles, not fundamental inputs.
Pre-existing metallicity floors (Be-9 abundances, deuterium scatter beyond BBN); pre-existing magnetic seed fields (IGM magnetogenesis tensions); ICM metallicity gradients without late-time enrichment models; quasar variability at non-standard timescales; high-z quasar clustering. Does not resolve the cosmological lithium problem — SCT BBN is identical to ΛCDM BBN, so the Li-7 factor-of-3 deficit is a shared open problem to be resolved in stellar depletion physics, not cosmology.
