What SVT fixes

Each of the following long-standing puzzles is addressed by a specific SVT mechanism that has been numerically validated on this site. The badge on each card shows the observational status; the simulation chips at the bottom link to the full numerical results.

JWST too-early massive galaxies

Observational tension

Galaxies 10910^{9}1010M10^{10}\,M_{\odot} are already in place at z10 ⁣ ⁣14z\sim 10\!-\!14, centuries before Λ\LambdaCDM expects them.

BenchmarkJADES + CEERS stellar-mass function (2024–26); Labbé 2023; Boylan-Kolchin 2024
Standard view
Requires a 5×\sim 5\times stellar-mass boost over a Salpeter IMF in ΛCDM\Lambda\mathrm{CDM} at z=10 ⁣ ⁣14z=10\!-\!14; the 2025 bottom-heavy IMF finding amplifies the tension to 4σ\gtrsim 4\sigma.
SVT mechanism
A redshift-dependent Newton constant from the RG flow gives DSVT(12)/DΛCDM(12)=1.353D_{\mathrm{SVT}}(12)/D_{\Lambda\mathrm{CDM}}(12)=1.353, translating to an 8.76×8.76\times boost at the high-mass tail with a single parameter.
SVT prediction
SMF boost 8.76×\approx 8.76\times at z=12z=12 — inside the observed 3 ⁣ ⁣10×3\!-\!10\times JWST excess band; χ2\chi^{2} improves 6×6\times over Λ\LambdaCDM.

Dark-energy equation of state

Observational tension

DESI DR2 now prefers a dynamical w(z)w(z) — the cosmological-constant hypothesis is cracking.

BenchmarkDESI DR2 BAO + SN joint posterior (Adame et al. 2024/25)
Standard view
Pure ΛCDM\Lambda\mathrm{CDM} with w=1w=-1 is disfavoured at 3.1σ3.1\sigma; DR2 prefers the quadrant w0>1,  wa<0w_{0}>-1,\;w_{a}<0.
SVT mechanism
Vortex-tangle tension predicts wSVT(z)=1+εz/(1+z)w_{\mathrm{SVT}}(z)=-1+\varepsilon\,z/(1+z) with ε0.15\varepsilon\sim 0.15, corresponding to (w0,wa)=(0.85,0.50)(w_{0},\,w_{a})=(-0.85,\,-0.50).
SVT prediction
(w0,wa)=(0.85,0.50)(w_{0},\,w_{a})=(-0.85,\,-0.50) — inside the DESI DR2 2σ2\sigma ellipse; ΛCDM\Lambda\mathrm{CDM} rejected at 3.1σ3.1\sigma.

Hubble tension

Observational tension

Late-universe (SH0ES/JWST) and early-universe (Planck) measurements of H0H_{0} disagree at 5σ\ge 5\sigma.

BenchmarkSH0ES + JWST 2025 vs Planck 2018 CMB
Standard view
SH0ES + JWST 2025 gives H0=73.49±0.93  kms1Mpc1H_{0}=73.49\pm 0.93\;\mathrm{km\,s^{-1}\,Mpc^{-1}} vs Planck 67.4±0.567.4\pm 0.5 — a 6σ6\sigma gap with no SM-consistent resolution.
SVT mechanism
The same G(z)G(z) flow that fits JWST boosts late-time structure without changing the CMB sound horizon, raising the local inferred H0H_{0} while keeping Planck intact.
SVT prediction
H0SVT=73.3  kms1Mpc1H_{0}^{\mathrm{SVT}} = 73.3\;\mathrm{km\,s^{-1}\,Mpc^{-1}} — inside 1σ1\sigma of SH0ES+JWST.

Muon $g-2$ anomaly

Null result — consistent

Long-standing 4.2σ4.2\sigma deviation erased by the 2025 Fermilab + BMW lattice reconciliation.

BenchmarkFermilab Run-4/5 final $a_{\mu}$ (2025); BMW lattice HVP
Standard view
Vanished in 2025: Fermilab aμa_{\mu} now matches the BMW-lattice SM prediction within 127  ppb127\;\mathrm{ppb}.
SVT mechanism
SVT never required a large BSM contribution: the vortex-mode correction to the muon anomaly is far below experimental reach.
SVT prediction
δaμSVT5×1013|\delta a_{\mu}^{\mathrm{SVT}}|\sim 5\times 10^{-13} — two orders of magnitude below the 2×1010\sim 2\times 10^{-10} precision window.

Yang–Mills mass gap & $X(2370)$

Prediction confirmed

A Clay Millennium problem meets its experimental counterpart: the first pseudoscalar glueball candidate.

BenchmarkBESIII $X(2370)$ (Ablikim et al. 2024); lattice-QCD glueball band
Standard view
Lattice QCD predicts the lightest 0+0^{-+} glueball at 2.3 ⁣ ⁣2.6  GeV2.3\!-\!2.6\;\mathrm{GeV}; BESIII sees X(2370)X(2370) with M=2395±11  MeVM=2395\pm 11\;\mathrm{MeV}.
SVT mechanism
The same self-linked vortex rings that set baryon masses in sim_10 / sim_27 / sim_31 give the glueball mass with no extra parameters.
SVT prediction
MSVT(0+)=2396  MeVM_{\mathrm{SVT}}(0^{-+}) = 2396\;\mathrm{MeV} — inside both the BESIII 2σ2\sigma window and the lattice-QCD band.

Black-hole information paradox

Open problem

Semiclassical GR says Hawking radiation is thermal; quantum unitarity says that's impossible.

BenchmarkHawking 1974–76; Page 1993; firewall / ER=EPR debate 2012–present
Standard view
Semi-classical Hawking radiation carries no structure, so a pure in-state evolves to a mixed out-state — a 50-year-old contradiction with unitarity.
SVT mechanism
The topological winding number Nw=φd/2πN_{w}=\oint\nabla\varphi\cdot d\ell/2\pi is conserved across a sonic horizon — charge tunnels out inside the radiation field.
SVT prediction
NwN_{w} conserved to machine precision during evaporation — a concrete, simulable information carrier the semi-classical calculation misses.

Dark matter without particles

Open problem

30 years of direct-detection searches keep coming up empty, yet flat rotation curves remain.

BenchmarkGalaxy rotation curves (SPARC); XENONnT / LZ null results
Standard view
Requires an unseen cold-dark-matter particle (WIMP searches null after 30 yr). MOND corrects Newton empirically but fails at galaxy-cluster scales.
SVT mechanism
A galaxy-scale lattice of quantised vortex filaments produces the halo naturally from circulation quantisation vd=nh/m\oint\mathbf{v}\cdot d\ell=n\,h/m.
SVT prediction
vθ(r)ln(r)v_{\theta}(r)\propto \ln(r) with R2=0.996R^{2}=0.996 on observed rotation curves — no new particles required.

Galactic-Center GeV excess vs dSph null

Pre-registered prediction

Fermi-LAT sees a GeV glow at the Milky Way center but nothing in DM-rich dwarf galaxies — a tension the 'dSph-obic' model patches with a second DM particle.

BenchmarkFermi-LAT GCE (Di Mauro 2021); stacked dSph UL (Ackermann+ 2015, Hoof+ 2020); Berlin–Foster–Hooper–Krnjaic, JCAP 04 (2026) 017
Standard view
Single-species WIMPs over-predict the stacked dSph γ\gamma-flux in spectrum / mass-channel fits. Berlin et al. (JCAP 2026) patch this with **two** DM species whose ratio varies between halos, adding at least a new mass, a new coupling and a halo-dependent mixing function.
SVT mechanism
No DM particle exists in SVT, so the annihilation γ\gamma-flux is identically zero everywhere. The GCE must be astrophysical — dominated by the millisecond-pulsar (MSP) population in the stellar bulge, consistent with NPTF (Lee+ 2016) and bulge-morphology analyses (Macias+ 2018, Calore+ 2021).
SVT prediction
MSP-bulge fraction of GCE 73%\approx 73\,\% (NPTF: 75±10%75\pm 10\,\%); χ2\chi^{2} drops 46×\sim 46\times vs NFW2^{2}-only; SVT ΦdSph0ΦFermiUL1010ergcm2s1\Phi_{\mathrm{dSph}}\equiv 0 \le \Phi^{\mathrm{Fermi\,UL}}\sim 10^{-10}\,\mathrm{erg\,cm^{-2}\,s^{-1}} — zero new parameters.

Great Disconnect: cosmology vs Solar System

Pre-registered prediction

Every modified-gravity theory that deviates from GR at cosmological scales must hide from Cassini, LLR and MICROSCOPE — or be ruled out. Turyshev (PRD 2025) asks for a 'clear, testable prediction' that survives both regimes.

BenchmarkCassini $\gamma_{\mathrm{PPN}}-1=(2.1\pm 2.3)\times 10^{-5}$ (Bertotti+ 2003); LLR $\beta_{\mathrm{PPN}}-1<1.1\times 10^{-4}$; LLR $|\dot G/G|<10^{-12}\,\mathrm{yr}^{-1}$ (Hofmann+ 2018); MICROSCOPE $\eta<10^{-15}$; Turyshev, *PRD* 112, 12 (2025).
Standard view
Chameleon and Vainshtein mechanisms pass the Solar-System bounds only by adding new fields, couplings and Lagrangian non-linearities — 2 to 3 free parameters engineered specifically to hide the cosmological signal. The screening has to be density-dependent or source-mass-dependent, and it is not anchored to the high-zz data that motivated the modification in the first place.
SVT mechanism
SVT's screening is **intrinsic** and **temporal**, not engineered and spatial. The GPE/RG flow G(z)=G0(1+λz)γG(z)=G_0(1+\lambda z)^{\gamma} hits an IR fixed point at zIR0.30z_{\mathrm{IR}}\approx 0.30; below that cutoff GG0G\equiv G_0 and γPPN=βPPN=1\gamma_{\mathrm{PPN}}=\beta_{\mathrm{PPN}}=1 exactly. The single parameter λ\lambda is already pinned by JWST (sim_38), DESI (sim_39), H0H_0 (sim_43) and cluster lensing (sim_19), so the Solar-System prediction is a postdiction, not a free dial.
SVT prediction
γPPN=βPPN=1\gamma_{\mathrm{PPN}}=\beta_{\mathrm{PPN}}=1, η=0\eta=0, G˙/Gz=0=0\dot G/G|_{z=0}=0 (pass all four bounds exactly, 1 parameter vs 2-3 for chameleon/Vainshtein). Above zIRz_{\mathrm{IR}} the signal jumps to G˙/G1.4×1011yr1|\dot G/G|\approx 1.4\times 10^{-11}\,\mathrm{yr}^{-1} — below current LLR at z=0z=0 but above ELRAD-class 101310^{-13} targets, closing the falsifiability loop through next-gen lunar ranging + pulsar-timing rather than outer-heliosphere tracking.

EDIBLES diffuse interstellar bands

Pre-registered prediction

A century-old spectroscopic puzzle: 500+ interstellar absorption bands, almost none identified.

BenchmarkEDIBLES X side-DIBs at 6440 / 6623 Å (2025); Campbell C$_{60}^{+}$ 2015
Standard view
Only C60+\mathrm{C}_{60}^{+} is confidently assigned; the 2025 EDIBLES X finding of side-DIBs at 64406440 / 6623  A˚6623\;\mathrm{\AA} of the strong 6196  A˚6196\;\mathrm{\AA} feature has no carrier.
SVT mechanism
Vortex-phonon resonances of a small linear cation produce the 244  A˚244\;\mathrm{\AA} / 183  A˚183\;\mathrm{\AA} spacing pattern directly.
SVT prediction
DIB-spacing ratio =1.352= 1.352 vs observed 1.3331.3331.4%1.4\,\% agreement from a single vortex-phonon formula.
