Falsifiable predictions & near-future tests

This page lists near-term and future observations whose outcomes can constrain, match, or rule out specific numerical implementations of SVT on this site. These facilities were built for mainstream ( $\Lambda\mathrm{CDM}$ + GR) science; the value here is contrast — what the simulations already fix or risk — not an endorsement by any experiment.

“Validate” / “Invalidate” are relative to the assumptions in the linked simulation pages, not claims about what collaborations will announce.

How to read the table

Cosmology / LSS — $G(z)$ , $w(z)$ , growth, lensing. Cross-checks: sim_05, sim_19, sim_38–39, sim_50.
Solar system / lab — PPN, Nordtvedt, $\dot G/G$ . Distinctive SVT: temporal (IR) vs spatial screening (sim_47).
Gravitational waves — beyond-GR ringdown (sim_40); 3G for precision later.
GeV–TeV gamma rays — no WIMP-annihilation halo in the SVT packaging (sim_06, sim_45, sim_52).

External years (Euclid DR1, LISA, Roman) follow public mission pages; re-check before citing in papers.

DESI (spectroscopic survey)

Ongoing; DR2-era cosmology 2024–27+

Lead: DOE/NSF, Berkeley Lab, NOIRLab

What it measures

Baryon acoustic oscillations, RSD / full-shape clustering, Lyman- $\alpha$ BAO, joint fits to $w_0$ , $w_a$ and $H_0$ .

SVT hook (this site)

Vortex-tangle / RG-motivated $w(z)$ and growth consistent with a dynamical low- $z$ equation of state; ties the same $G(z)$ / $\lambda$ sector used for JWST and $H_0$ .

Tends to validate (if…)

Persistent preference (with robust systematics) for $w_0>-1$ , $w_a<0$ in the same quadrant as the DE simulation; internal consistency of distance/growth with variable- $G$ growth factor.

Tends to invalidate (if…)

A return to exact $\Lambda$ with no residual cross-probe tension while the rest of the site’s $G(z)$ / early-galaxy program remains fixed — would require re-deriving the whole RG story.

Sims:sim_39 sim_24 sim_05

DESI

Euclid (space telescope)

Survey ongoing; Euclid DR1 scheduled Oct 2026 (ESA COSMOS planning)

Lead: ESA (NASA etc.)

What it measures

Weak lensing, galaxy clustering, photometric redshifts, CMB cross-correlation, tight $\Omega_m$ , $\sigma_8$ , $w(z)$ , growth.

SVT hook (this site)

Tightens $(\lambda, z_{\rm IR})$ -style joint posteriors used in the “falsifiability bridge” to Solar-System $\dot G/G$ forecasts (sim_50).

Tends to validate (if…)

Euclid-era posteriors for $\lambda$ remain compatible with sim_05 / sim_38 pins; no forced drift of $G(z)$ parameters when combined with CMB/BAO.

Tends to invalidate (if…)

A high-significance exclusion of the RG trajectory or growth pattern implied by a single shared $\lambda$ across probes (if held rigid), without a consistent recalibration of the flow.

Sims:sim_50 sim_19

Euclid @ ESAEuclid DR1 (COSMOS)

Nancy Grace Roman Space Telescope

NET Sept 2026 (NASA 2026 schedule); 5+ yr primary mission

Lead: NASA / GSFC

What it measures

Wide-field IR imaging and slitless spectroscopy: dark energy, large-scale structure, time-domain SNe; complements Euclid.

SVT hook (this site)

Independent stress test on $w(z)$ , bias, and SN Hubble diagram — does the same DE / growth locus survive Roman systematics budgets?

Tends to validate (if…)

Roman + Euclid + DESI convergence on the $(w_0,w_a)$ -like locus the site’s DE sims use.

Tends to invalidate (if…)

Incompatible $w(z)$ or growth with Roman+photo- $z$ systematics if the SVT side refuses any flexibility in the effective DE parametrization.

Sims:sim_50 sim_24

Roman @ NASA

Vera C. Rubin Observatory / LSST

Commissioning 2024–26+; 10-yr LSST (Legacy Survey of Space and Time)

Lead: NSF & DOE

What it measures

Deep wide-field photometry, weak lensing, SN cosmology, solar-system astrometry via LSST:ISS.

SVT hook (this site)

LSS + SN: sharp tests of growth, $S_8$ , baryon feedback. Galaxy–galaxy lensing stresses mass models without a particle annihilation channel.

Tends to validate (if…)

LSS + SN remain in the same broad islands as Euclid/DESI; no new forced parameters beyond effective DE + standard neutrino extensions.

Tends to invalidate (if…)

A model-independent $w(z)$ or growth reconstruction that rules out the entire RG / tangle class if the theory is not generalized.

Sims:sim_39 sim_19

Rubin/LSST

Simons Observatory (ground CMB)

LAT milestones 2025+; years of CMB + foreground separation

Lead: Simons Foundation / intl. collaboration

What it measures

High-sensitivity CMB $T$ / $E$ / $B$ , $N_{\rm eff}$ , $\Sigma m_\nu$ , joint with LSS for $\Lambda$ vs dynamical DE.

SVT hook (this site)

CMB pins the early universe; late $w_0$ / $w_a$ from DESI/Rubin/Euclid must stay jointly consistent with the same flow parameters.

Tends to validate (if…)

Joint analyses allow the mild low- $z$ $w(z)$ pull seen in BAO+SN with standard $N_{\rm eff}$ and light neutrinos.

Tends to invalidate (if…)

A joint fit that forces exact $\Lambda$ and removes all low- $z$ tension with zero extension, while the site requires time-varying $w$ (scenario-dependent).

Sims:sim_39 sim_24

Simons Observatory

CMB next generation (global)

2020s–2030s. Note: U.S. CMB-S4 construction was discontinued (DOE/NSF, 2025).

Lead: SO, LiteBIRD, South Pole & Atacama programs, …

What it measures

Tensor mode, neutrino mass, $N_{\rm eff}$ ; reionization; check project sites for the active facilities.

SVT hook (this site)

Mostly early-universe. Distinct SVT claims on this site are late universe + gravity unless you add a specific inflation / $r$ embedding.

Tends to validate (if…)

—

Tends to invalidate (if…)

Data incompatible with any single global expansion history that also fits the late-universe $G(z)$ /DE sims (would need a new early/late link).

Sims:sim_39

CMB-S4 (project archive)

JWST & 30m-class ELTs

Ongoing cycles; decade of high-$z$ spectroscopy

Lead: NASA/ESA/CSA; ESO E-ELT, GMT, TMT

What it measures

SMF, SMBH masses, IGM/metals, LRD/AGN demographics at $z=4$ – $15$ .

SVT hook (this site)

The same $G(z)$ that fits DESI and $H_0$ must not break LRD abundance and $M_{\rm BH}/M_*$ scaling without extra knobs (sim_55).

Tends to validate (if…)

High- $z$ overmassive SMBH / LRD rates stay in the SVT-boost bands when RG parameters are fixed by cosmology.

Tends to invalidate (if…)

A baryon+seed+IMF story that fully explains the same populations with $G=G_0$ and no RG extension (pressures the G-boost layer).

Sims:sim_38 sim_55

JWST @ STScI

LIGO / Virgo / KAGRA & Einstein Telescope

O4 ongoing; O5 ~2027+; ET first science 2030s (roadmap estimates vary)

Lead: LIGO / Virgo / KAGRA; future ET/CE

What it measures

BBH/NS mergers; ringdown; propagation; rates vs $z$ ; 3G strong-field tests.

SVT hook (this site)

Signed prediction in this repo: excess effective damping in ringdown tails vs Kerr (sim_40) — a sharp GR test.

Tends to validate (if…)

Mass- and spin-resolved positive offset in ringdown damping at the predicted level, not explained by waveform systematics.

Tends to invalidate (if…)

No GR deviation in ringdown after systematics and higher modes — falsifies the ringdown sim as a physical SVT handle (the rest of the program can be renegotiated).

Sims:sim_40

LIGOEinstein Telescope

LISA (space-based GW)

Launch planned ~2035 (ESA)

Lead: ESA (NASA hardware contribution)

What it measures

mHz GWs: massive BBH, Galactic binaries, multi-band with ground network.

SVT hook (this site)

No LISA-specific signed SVT metric in the current sim suite. ET/LIGO ringdown (sim_40) is the clear near-term handle; LISA is future if/when you add a firm propagation or SGWB prediction.

Tends to validate (if…)

Future work: only after a published SVT waveform/propagation number.

Tends to invalidate (if…)

N/A for the codebase as shipped today.

Sims:sim_40

LISA @ ESA

Lunar laser ranging & new retroreflectors

Continuous; NGLR-class hardware 2020s+

Lead: APOLLO, Grasse, Wettzell, Artemis/CLPS partners

What it measures

Earth–Moon range, PPN, Nordtvedt $\eta$ , tight bounds on $\dot G/G$ (indirect).

SVT hook (this site)

IR fixed point: $\dot G/G|_{z=0}=0$ ; cosmological $\dot G/G$ is a post-IR object — joint with Euclid/DESI (sim_50) not LLR in isolation.

Tends to validate (if…)

Joint $\lambda$ closure between cosmology and solar-system PPN/LLR; or post-IR $\dot G/G$ in a band consistent with the bridge, not a present-day non-zero G-dot.

Tends to invalidate (if…)

A robust non-zero $\dot G/G$ today above systematics — inconsistent with sim_46–50 unless the IR structure changes.

Sims:sim_46 sim_50 sim_48

ILRS

LATOR-class Shapiro & astrometry (concept)

Decadal / concept — see Turyshev et al. proposals

Lead: NASA JPL / community (not yet a flight program)

What it measures

PPN $\gamma$ to $\sim 10^{-8}$ ; sub-ppb Shapiro; solar quadrupole.

SVT hook (this site)

A null in $\gamma-1$ at the LATOR target can falsify a specific RG link to PPN if $\lambda$ is fixed by cosmology (see Problems + sim_50).

Tends to validate (if…)

Non-zero $\gamma-1$ at the $10^{-7}$ – $10^{-6}$ order if the EFT link is as stated (very high bar).

Tends to invalidate (if…)

Tight null on $\gamma-1$ at $10^{-8}$ with a confirmed cosmology pin on $\lambda$ that leaves no consistent exponent in the published bridge — falsifies that construction.

Sims:sim_46 sim_50

LATOR (arXiv)

Interstellar Probe (deep-space, concept)

2030s+ if selected

Lead: NASA heliophysics / community

What it measures

Precision range & Doppler at 10– $10^3$ AU; heliospheric gravity tests.

SVT hook (this site)

sim_49: SVT-IR suppresses large fifth-force style anomalies; bounded $|a|$ in the outer solar system.

Tends to validate (if…)

Anomalies below the SVT-IR cap used in the sim, consistent with known systematics.

Tends to invalidate (if…)

A robust new long-range force in the outer system matching a competing density-screened model but not the temporal-IR SVT class.

Sims:sim_49

Fermi-LAT, CTA, IACTs

Ongoing; stacked analyses every few years

Lead: NASA / CTA / IACT consortia

What it measures

dSph stacked limits; Galactic Center excess; TeV blazar fast variability.

SVT hook (this site)

No thermal-WIMP annihilation from a phonon lattice (sim_06). GCE = astrophysics (sim_45). Blazar $t_{\min}\sim r_g/c\,\delta^{-1}$ (sim_52).

Tends to validate (if…)

dSphs stay dark in annihilation; GCE remains MSP-consistent; blazar $t_{\min}$ vs $M_{\rm BH}$ and beaming as in sim_52.

Tends to invalidate (if…)

5 $\sigma$ thermal-WIMP spectrum from a dSph stack, or blazar $t_{\min}$ data incompatible with the $r_g/c$ lower bound (after beaming).

Sims:sim_45 sim_06 sim_52

Fermi

XENONnT, LZ, PandaX (direct detection)

Ongoing; ton$\times$yr exposure growing

Lead: Liquid-xenon collaborations

What it measures

Nuclear recoils; solar- $\nu$ floor; sub-GeV models.

SVT hook (this site)

SVT lattice here is a gravitational / rotating-medium story, not a WIMP target. Nulls are weak consistency; a WIMP discovery does not auto-falsify SVT unless you commit to zero particle component.

Tends to validate (if…)

Continued nulls — weakly consistent with no thermal relic in the halo.

Tends to invalidate (if…)

A replicated WIMP spectrum plus a thermal-halo story that subsumes all rotation-curve and cluster evidence without the lattice (pressures the particle-free packaging).

Sims:sim_06 sim_35

XENONnT

HL-LHC & FCC studies

LHC through 2020s–30s; FCC ~2040s

Lead: CERN / intl. partners

What it measures

Higgs couplings, BSM scalars, precision EW, long-lived states.

SVT hook (this site)

This repo is not a full BSM replacement. SVT particle predictions need QFT-level cross-sections — only a few hadron benchmarks (sim_31, sim_44, etc.).

Tends to validate (if…)

—

Tends to invalidate (if…)

A long-range fifth scalar coupled to SM matter incompatible with the joint solar-system + CMB embedding as coded would force a screening/EFT redesign.

Sims:sim_31

CERN

DUNE, JUNO, KATRIN, Project 8

2020s–2040s

Lead: DOE, Fermilab, ORNL, intl. partners

What it measures

Mass ordering, absolute $m_\nu$ , CNB; lab vs CMB $\Sigma m_\nu$ .

SVT hook (this site)

Largely orthogonal to the gravity sims, unless you lock incompatible $\Sigma m_\nu$ priors in joint fits with DE extensions (see sim_21 for oscillation narrative).

Tends to validate (if…)

Lab + cosmology $\Sigma m_\nu$ consistent with your global fits.

Tends to invalidate (if…)

Incompatible $\Sigma m_\nu$ if your joint model over-constrains the neutrino sector.
