Predictions & Hypotheses

Test protocol

Statistical analysis of LHC datasets for non-Gaussian patterns at extreme energies. Requires: ≥10⁷ collision events at √s ≥ 13 TeV, position uncertainty distributions, model-independent deviation test.

Falsification condition

Falsified if LHC collision data shows no non-Gaussian signature in position uncertainty distributions beyond 3σ above the Heisenberg baseline across ≥10⁷ collision events at √s ≥ 13 TeV.

Bridge and current state of evidence

Loop Quantum Gravity (Rovelli, Smolin) predicts a discrete spacetime lattice at the Planck scale.

Test protocol

Controlled experiment: identical reactions with and without targeted ultrasonic frequency. Measure rate and yield. Requires: ≥3 independent reaction pairs, frequency-matched vs. off-frequency vs. silent control, rate measured at identical energy input.

Falsification condition

Falsified if matched-frequency exposure produces ≤5% reaction-rate enhancement over off-frequency control at p<0.05 in ≥3 independent experiments on distinct reaction pairs, after controlling for cavitation effects.

Bridge and current state of evidence

Sonochemistry already shows non-trivial rate enhancement (Suslick, Science 1990). Spectrum predicts frequency-specificity beyond cavitation.

Test protocol

Pulsar Timing Array data (NANOGrav 15yr, public) analysed for resonance peaks not explained by known gravitational-wave sources. Specific target: spectral lines at frequencies predicted from halo-density models.

Falsification condition

Falsified if NANOGrav 15-year dataset shows no statistically significant spectral line in the PTA background after subtracting the modelled gravitational-wave background, at p<0.01 with correction for multiple frequency bins — provided the frequency band derived from the halo-density model lies inside the mass range covered by the published NANOGrav deterministic ULDM search. Stating that predicted band explicitly, and checking it against the searched range, is a precondition for this prediction remaining open: if it falls inside, the published null already applies.

Bridge and current state of evidence

NANOGrav (2023) detected a stochastic gravitational-wave background — its astrophysical interpretation is open. The deterministic search this prediction calls for has, however, already been run: the NANOGrav Collaboration searched the 15-year data set for deterministic ultralight-dark-matter signals and for Milky Way dark-matter substructure, found no evidence for either, and reported updated exclusions that outperform torsion-balance and atomic-clock constraints for ULDM coupled to electrons, muons or gluons (Afzal et al., ApJL 951, L11, 2023, doi:10.3847/2041-8213/acdc91). This prediction is therefore only still open in the range that search did not cover.

Test protocol

High-precision membrane oscillation measurement via AFM or optical trapping on ≥10 distinct cell types, correlated with predicted eigenfrequency (calculated from membrane mass/area/tension).

Falsification condition

Falsified if AFM measurement of ≥10 distinct cell types shows correlation coefficient r<0.3 between predicted eigenfrequency (from membrane mass and composition) and measured primary oscillation peak, across ≥3 independent labs.

Bridge and current state of evidence

Popp biophoton measurements support frequency-specificity. Direct membrane measurement is the next step.

Test protocol

Blind test: measure interference pattern, derive frequency via λ = (d × Δy) / D, compare with known source. Extend to unconventional frequency bands (sub-THz, ELF).

Falsification condition

Falsified if frequency derived from interference pattern deviates from known source frequency by >1% in ≥3 controlled calibration experiments in non-standard frequency bands (below 1 GHz or above 100 THz).

Bridge and current state of evidence

Diffraction is established physics. Spectrum claims extension into unconventional frequency bands as a universal frequency meter.

Test protocol

Impulse-response measurement (hammer + accelerometer) on ≥20 megalithic blocks at ≥3 sites of varying composition and geometry. Record first three resonance modes per block.

Falsification condition

Falsified if ≥70% of tested megalithic blocks show all primary resonance peaks outside the 20 Hz – 5 kHz range, or if the distribution is indistinguishable from random-geometry quarried blocks of the same material.

Bridge and current state of evidence

Stonehenge acoustics already studied (Till & Fazenda, JASA 2012). Feasible with existing equipment.

Test protocol

Comparative study: ≥30 practitioners vs. ≥30 age-matched controls, biophoton emission measured before and after a standardised 60-minute practice session, blinded analysis.

Falsification condition

Falsified if practitioners show no statistically significant biophoton coherence difference versus matched controls at p<0.05 in both pre-session and post-session measurements, in ≥2 independent studies.

Bridge and current state of evidence

Popp's measurement protocol exists. Glen Rein has done comparable work on intention-experiments.

Test protocol

Block on insulator → acoustic excitation at calculated eigenfrequency → measure voltage with oscilloscope. Control: excitation at off-resonance frequency. Predict: ≥100 nV at resonance, <10 nV off-resonance.

Falsification condition

Falsified if ≥5 independent granite blocks show <50 nV voltage signal at their calculated acoustic eigenfrequency, or if the resonance/off-resonance voltage ratio is ≤2× in blinded measurements.

Bridge and current state of evidence

Quartz piezoelectricity is established. Scaling to block-level is feasible with existing instruments.

Test protocol

SQUID magnetometer measurements (μT range) around a group of ≥10 people before, during, and after synchronous heart-coherence exercise (HeartMath protocol). Blinded comparison to non-coherent baseline.

Falsification condition

Falsified if ≥5 independent group sessions show no statistically significant local EM-field difference (>2σ) between coherent heart-meditation and non-coherent baseline, using calibrated SQUID magnetometers in shielded environments.

Bridge and current state of evidence

HeartMath has measured individual coherence. Group-level EM-field extension is the novel claim.

Test protocol

Identical reactions, separated enantiomers, exposed to the same resonance frequency. Measure rate and yield for L vs. D form. Minimum detectable difference: 5% rate enhancement at p<0.05.

Falsification condition

Falsified if ≥3 enantiomer pairs under targeted resonance frequencies show reaction-rate differences ≤2% between L and D forms at p<0.05, after controlling for cavitation and thermal effects.

Bridge and current state of evidence

CISS effect (PNAS 2022) confirms chirality acts as a physical filter on spin-polarised electrons.

Test protocol

Compare EM emission of cells with intact DNA vs. fragmented DNA (DNase-treated); intact should show a coherent peak at the DNA helix frequency. Photomultiplier + interferometric setup, blinded analysis, ≥3 independent replicates.

Falsification condition

Falsified if EM emission spectra of intact-DNA cells show no coherent peak distinguishable from DNase-fragmented cells in ≥3 independent photomultiplier measurements using blinded spectral analysis.

Bridge and current state of evidence

Popp biophotons confirm coherent cellular emission. The hypothesis specifies that the DNA helix is the carrier.

Test protocol

Identical plants (same species, batch, pot size), three sound conditions (φ-ratio frequency / random frequency / silence). Measure stem length, leaf count, and dry weight over 4 weeks. n≥20 per group.

Falsification condition

Falsified if φ-frequency exposed plants show ≤5% growth difference (stem length or dry weight) versus random-frequency and silent controls at p<0.05 across ≥3 independent trials of n≥20 plants per group.

Bridge and current state of evidence

Phyllotaxis (137.5° = 360°/φ²) shows plants already grow on φ-patterns. The hypothesis predicts external φ-frequencies amplify this.

Test protocol

Replicate calibrated Casimir setup with sensitive force sensors. Apply asymmetric pulsed EM field; measure force vs. classical Casimir baseline. Vary EM geometry and frequency. Control rigorously for thermal, magnetic, electrostatic, and ion-wind artefacts. Repeat across ≥3 independent laboratories.

Falsification condition

Falsified if asymmetric pulsed EM in calibrated Casimir geometry produces force deviation ≤2% above classical Casimir baseline at p<0.05 in ≥3 independent replications, after ruling out ion wind, thermal drift, and electrostatic artefacts.

Bridge and current state of evidence

Casimir effect is established physics (Casimir 1948; Lamoreaux 1997). The grid model predicts the substrate responds to field geometry beyond passive zero-point — a measurable cross-modulation signal at force-sensor precision.

Test protocol

Generate intense, short EM pulse in ultra-high-vacuum chamber. Detect with ultra-sensitive receivers tuned for sub-quantum-noise echo signals. Vary pulse strength and verify proportional echo-amplitude scaling. Control for wall reflections, thermal effects, residual-gas re-radiation, and Casimir background.

Falsification condition

Falsified if no echo signal above quantum noise floor is detected after ≥10 calibrated EM pulses in high vacuum across ≥2 independent laboratories, after ruling out wall reflections, thermal effects, and residual-gas re-radiation.

Bridge and current state of evidence

Standard quantum field theory predicts no echo from vacuum after a passing pulse — the vacuum is purely passive. The grid model predicts grid cells passively store and re-emit energy on a short timescale, producing a measurable signature.

Test protocol

Prepare entangled photon pair in controlled environment. Measure total energy before and after decoherence with calorimetric precision. Look for consistent energy deficit not explained by detection efficiency or thermal effects. Vary decoherence type (thermal, mechanical, photonic) and verify the loss is constant per decoherence event.

Falsification condition

Falsified if blinded calorimetric measurement across ≥2 independent calorimetry-grade quantum systems shows energy balance consistent with QM-predicted exact conservation at p>0.05, after sufficient event counts to resolve a hypothesised dissipation at the calorimeter's noise floor.

Bridge and current state of evidence

Decoherence theory (Zurek, Joos, Zeh) treats decoherence as wavefunction–environment entanglement with no net energy loss to the system. The grid model predicts a small but measurable dissipation into the substrate itself — a class of test that is currently at the edge of available calorimetry.

Test protocol

Three conditions: φ-spaced series, random series, silence. HRV (HeartMath protocol: LF/HF ratio, coherence score) as outcome measure. ≥50 subjects, crossover design, blinded analysis.

Falsification condition

Falsified if ≥50 subjects show HRV coherence score statistically indistinguishable between φ-spaced and randomly-spaced frequency series at p>0.05 in blinded crossover measurement.

Bridge and current state of evidence

φ-frequencies minimise destructive interference → standing waves remain stable longer → biological systems can phase-lock more easily.

Test protocol

Elements Z=113–118 have all been synthesised and named (2016), and their properties are partly measured and extensively calculated, so this is testable now rather than eventually. The content of the test is narrow and worth stating precisely: whether one relativistic-correction factor per element reproduces those properties without per-element tuning, and whether it does so anywhere that standard relativistic quantum chemistry does not already succeed.

Falsification condition

Falsified if the monotonic relativistic-correction-factor model cannot reproduce the measured and calculated properties of Z=113–118, or if it requires separate free parameters per anomaly (i.e. is not predictive). Falsified as a distinct claim — that is, reduced to relabelling — if every anomaly it captures is already captured by standard relativistic quantum chemistry through Zα, with no case where the two accounts diverge and the frequency reading proves right. Agreement with the standard account is explicitly not evidence for the reframing; only a divergence resolved in its favour would be.

Bridge and current state of evidence

Pyykkö (1988, Chem. Rev. 88, 563, doi:10.1021/cr00085a006) is the canonical review of relativistic quantum chemistry — the yellow of gold follows from the relativistically narrowed 5d→6s gap, and the same family of effects covers the other anomalies. Spectrum reframes that gradient as a frequency-scale phenomenon, and two limits of the reframing belong in the entry itself. First, "heavier elements occupy higher Compton frequencies" is true by definition: ν_C = mc²/h is a restatement of mass, so no measurement can confirm it and it carries no empirical content on its own. Citing a 1988 result as confirmation of it would be accommodation, not confirmation, and this entry no longer does so. Second, the quantity that governs these anomalies in the standard account is nuclear charge through Zα — inner s-electrons in heavy atoms moving at an appreciable fraction of c, contracting s and p₁ᐟ₂ orbitals while d and f expand — not the atom's Compton frequency. Because Z and mass rise together across the periodic table, a frequency relabelling will track the anomalies without thereby explaining them. What would make this more than a relabelling is a prediction the Zα account does not already make.

Test protocol

Cell culture or Popp-detector measurement → baseline → φ-frequency exposure vs. random series vs. silence → repeat measurement. ≥3 independent replicates, blinded spectral analysis.

Falsification condition

Falsified if ≥3 independent cell-culture experiments show biophoton coherence change ≤10% between φ-spaced exposure and random-frequency control after 30-minute exposure, using blinded photomultiplier analysis at p>0.05.

Bridge and current state of evidence

Popp's protocol exists. DNA φ-geometry (Harel 2021) suggests φ-frequencies should couple constructively.

Test protocol

Synthesise molecule pairs with matched vibrational profiles (IR spectrum) but distinct geometries. Blinded smell test with ≥30 trained assessors + olfactory receptor activation measurement. Predict: >70% confusion between matched-vibration pairs.

Falsification condition

Falsified if a blinded panel of ≥30 trained assessors reliably distinguishes (>80% accuracy) molecule pairs with matched vibrational profiles but distinct geometries, or if receptor activation profiles are distinct for matched-vibration pairs. Falsified equally by the converse arm: if heterologously expressed human olfactory receptors respond indistinguishably to isotopomer pairs that share molecular shape but differ measurably in vibrational spectrum, across ≥3 receptors whose relevance to the human percept has been independently established. "Independently established" is meant operationally, not as an open-ended escape: deorphanisation of the receptor plus a demonstrated genotype–percept link in humans, on the model of OR7D4 and androstenone. Block et al. (2015) reported this result for two receptors (human OR5AN1, mouse MOR244-3), so the arm is currently unmet on both counts — receptor count and relevance. If three such receptors are characterised and respond indistinguishably to shape-matched isotopomer pairs, this prediction is falsified and must be recorded as such rather than re-scoped.

Bridge and current state of evidence

Turin's vibration theory has competing experimental support. The forward test — matched-vibration / different-shape molecules — has still not been done definitively. The converse test has: Block et al. (PNAS 2015, 112:E2766) reported that the human musk receptor OR5AN1 and mouse MOR244-3 responded indistinguishably to deuterated, ¹³C-substituted and unsubstituted isotopomers in a heterologous expression system — pairs with matched shape but shifted vibrational spectra — and attributed reported perceptual differences to perireceptor processes or odorant impurity. Turin et al. replied (PNAS 2015, 112:E3154) that OR5AN1 may not be the receptor mediating the human percept. Block et al. answered in turn (PNAS 2015, 112:E3155), discounting the alternative receptors proposed and pointing to an NMR-visible impurity in the deuterated cyclopentadecanone that standard purification does not remove. Turin's objection is testable rather than resolving; on present evidence the receptor-level case for vibration reading is unsupported.

Test protocol

Three conditions: spontaneous breath, 0.2 Hz paced, 0.1 Hz paced. Measure HRV coherence + EEG-theta power + Popp biophotons simultaneously. ≥20 subjects. Predicted maximum coherence in all three at 0.2 Hz.

Falsification condition

Falsified if ≥20 subjects show no simultaneous peak in all three domains (HRV, EEG-theta, biophoton) at 0.2 Hz vs. 0.1 Hz or spontaneous, in blinded crossover analysis at p<0.05.

Bridge and current state of evidence

Slow breathing already known to enhance HRV coherence. Three-domain simultaneous measurement is the novel test.

Test protocol

Statistical analysis of frequency ratios across the full table → compute ratio distribution → test for φ-clustering against a permutation-derived null distribution. Requires: complete planetary-frequency table, ≥10,000 permutations. Three design constraints are mandatory, because without them the test cannot fail. (1) Pre-register the tolerance window and the exact list of admitted targets before inspecting the data — admitting φ, 1/φ, φ², √φ and φ·2ⁿ simultaneously multiplies the hit rate several-fold. (2) Account for multiplicity: n frequencies yield n(n−1)/2 pairwise ratios, so a set of 20 gives 190 chances. (3) Run the identical pipeline for decoy constants and require φ to be a significant outlier relative to them, not merely above a uniform-random null. Decoys must satisfy two conditions, which rules out the obvious choices: each must lie at least two tolerance windows from φ, and none may be a small-integer ratio. Both conditions matter. At a ±5% window, 1.7 is only 5.1% from φ and therefore not separable from it, while 1.5 is the 3:2 mean-motion resonance and is genuinely over-represented in planetary systems — a decoy that is itself physically privileged proves nothing. The second condition needs a bound to be meaningful, since the rationals are dense: read it as no ratio of two integers each ≤ 5. Workable set at a ±3% window: π, e and √2. Two exclusions show the discipline is real rather than decorative. Apéry's constant ζ(3) ≈ 1.202 fails, sitting 0.17% from 6:5. And at a ±5% window π itself fails, sitting 4.7% from 3:1 — so either tighten the window or drop π, but do not keep both. Note the same trap in reverse: the just-intonation major sixth 5:3 ≈ 1.667 sits within 3% of φ, so small-integer ratios must be excluded from the target list as well as from the decoys, and reported as a confound rather than a hit.

Falsification condition

Falsified if φ-clustering in planetary-frequency ratios is not a significant outlier against decoy constants (π, e, √2 at a ±3% window — each at least two tolerance windows from φ and at least one window from any ratio of two integers ≤ 5) run through an identical pre-registered pipeline, at p<0.05 using a permutation test with ≥10,000 samples over frequency sets matched on range, count and log-spacing. The decoy comparison — not the uniform-random null — is the decisive criterion: log-spaced sets generate near-φ ratios for reasons unrelated to φ, so beating a uniform null establishes nothing.

Bridge and current state of evidence

Phyllotaxis demonstrates φ-selection in biology, and there it has a generative mechanism: optimal packing, with φ favoured because its continued-fraction expansion makes it the most poorly approximable irrational. That is the standard by which this prediction should be judged — φ is meaningful where a mechanism forces it, and an artefact where it is merely found in a ratio table after the fact. Planetary spacing (Bode's law) suggests something analogous at solar-system scale, but no comparable mechanism has been demonstrated there.

Test protocol

In principle testable at particle accelerators (CERN, FAIR) with chiral molecular ions. Requires: ion beam of known chirality, positron target, precision cross-section measurement.

Falsification condition

Falsified if annihilation cross-section of chiral molecular ions equals that of achiral pairs within 1% measurement uncertainty across ≥3 independent accelerator experiments.

Bridge and current state of evidence

Antimatter symmetry tested for fundamental particles; chiral-molecule antimatter symmetry remains unprobed.

Test protocol

Lattice QCD already approaches this (~5% accuracy, Dürr et al., Science 2008). A grid-model deriving proton mass from grid parameters would strongly support the framework.

Falsification condition

Falsified if a grid-model calculation requires quark masses as a free input parameter to achieve >85% proton-mass accuracy — i.e., if grid parameters alone cannot reproduce the known proton mass (938.3 MeV) within 15% without quark-mass tuning.

Bridge and current state of evidence

Lattice QCD: 99% of proton mass is emergent from field interactions, not from fundamental mass parameters.

Test protocol

Simultaneous gravitational-wave and neutrino observation of neutron-star mergers (LIGO + IceCube/KM3NeT). Test: does neutrino flux show amplitude modulation correlated with the gravitational chirp signal?

Falsification condition

Falsified if simultaneous LIGO + IceCube observations of ≥5 neutron-star mergers show neutrino flux completely uncorrelated with gravitational-wave amplitude modulation at p>0.05 in blind cross-correlation analysis.

Bridge and current state of evidence

Multimessenger astronomy already combines gravitational-wave + EM observations; neutrino-gravitational-wave correlation under extreme conditions is the proposed extension.

Test protocol

Two tests, and the second is the one that carries weight. (a) Statistical analysis of the Kepler exoplanet catalogue: compute orbital-spacing ratios and compare against a null distribution of dynamically packed systems — not against uniformly randomised spacings. (b) Out-of-sample prediction: derive periods for undetected planets in specific systems, then search the photometry for them. Test (b) is decisive because it cannot be satisfied by fitting free parameters to systems already selected for completeness.

Falsification condition

Falsified if the observed orbital-spacing distribution is indistinguishable from a null built from dynamically packed, stability-limited systems at p<0.05 using ≥10,000 permutations, after controlling for observational selection bias. A null of uniformly randomised spacings is explicitly not sufficient: log-spacing arises generically from packing and stability constraints, so rejecting a uniform null demonstrates nothing about resonance. Falsified independently if out-of-sample period predictions continue to recover planets at or below the rate reported by Huang & Bakos (2014) once transit-probability prioritisation is applied.

Bridge and current state of evidence

Bovaird & Lineweaver (2013, MNRAS 435:1126) reported that most Kepler systems with four or more detected planets adhere to a generalised Titius–Bode relation at least as well as the Solar system, and used it to predict 141 additional planets. The out-of-sample follow-up was largely negative: Huang & Bakos (2014, MNRAS 442:674) searched Kepler long-cadence photometry for 97 of those predicted planets across 56 systems and recovered five candidates — not confirmed planets, and below the lower bound of the expected yield even after correcting for detection bias — and found the relation appears to overpredict pairs near the 3:2 resonance. Bovaird, Lineweaver & Jacobsen (2015, MNRAS 448:3608) replied by prioritising predictions on transit probability; as of this writing no published search has reported the yield of that prioritised sample, so the second falsification arm below is untested rather than passed. The deeper problem is interpretive rather than statistical: Graner & Dubrulle (1994, A&A 282:262) argued TB-like spacing follows from scale invariance of the protoplanetary disc, and their companion paper (A&A 282:269) concluded that a TB law follows from so many models that it constrains formation theories hardly at all. Dynamical packing produces approximately log-spaced orbits generically — so the empirical pattern does not by itself require a substrate-resonance mechanism. The grid model proposes one; it has not been shown to outperform the disc-dynamics account.

Test protocol

SEM/EDS of ≥10 mark edges vs. ≥10 uncut reference surfaces on at least two geographically independent sites (priority: Aswan granite + Sacsayhuamán andesite); modern reproduction with calibrated ultrasonic tool at quartz lattice frequency (~20 kHz). Cross-site agreement would significantly strengthen the shared-mechanism claim.

Falsification condition

Falsified if SEM/EDS analysis of ≥10 scoop-mark samples shows no statistically significant quartz enrichment at cut edges vs. uncut surface, and no piezoelectric polarisation traces distinguishable from random mechanical cutting.

Bridge and current state of evidence

Quartz piezoelectricity is established physics. The global distribution of morphologically similar marks across independent cultures makes a shared tooling mechanism more parsimonious than independent invention of morphologically similar precision features at unconnected sites. The archaeological claim remains testable via materials science regardless of origin.

Test protocol

≥20 healthy subjects, baseline + 4-hour post-intake plasma/urine sample, THz-TDS measurement at both timepoints. Blinded spectral comparison. Peak concentration window: 3–5 hours post D3 oral intake.

Falsification condition

Falsified if blinded THz-TDS analysis of ≥20 subjects shows plasma/urine spectra at 4-hour post-intake statistically indistinguishable from baseline in the 0.5–3 THz band at p>0.05 (corrected for multiple comparisons).

Bridge and current state of evidence

THz spectroscopy of biological water is an active research area. Novel claim: dissolved cargo modulates the water-THz network in a compound-specific, measurable way.

Test protocol

≥30 subjects, photomultiplier tube in dark chamber, three zones per subject, Popp-style protocol. Blinded zone labelling. Predict: monotone decrease in coherence from pigmented → grey zone.

Falsification condition

Falsified if biophoton emission from pigmented, mixed, and grey follicle zones is statistically indistinguishable in ≥30 subjects using Popp-protocol photomultiplier measurement in blinded analysis at p>0.05.

Bridge and current state of evidence

Popp emission patterns vary with metabolic state. Hair pigmentation transition is a well-defined, measurable metabolic shift.

Test protocol

MEG measurement before, during, and after administration of a clinically approved 5-HT2A antagonist, in a blinded crossover design. Compute spatial coherence radius (e.g. extent of phase-locked oscillations across sensor array) and compare against baseline. Predict: radius expands during blockade, returns to baseline after washout.

Falsification condition

Falsified if MEG measurement under 5-HT2A blockade shows spatial coherence-radius indistinguishable from baseline in ≥2 independent crossover studies at p>0.05, after controlling for amplitude effects, motion artefacts, and pharmacokinetic timing.

Bridge and current state of evidence

McFadden CEMI theory (J. Consciousness Studies, 2013 — closed-loop update of 2002 original) treats consciousness as a coherent EM field that couples back to the neurons. The filter hypothesis (Bergson 1896 → James 1898 → Huxley 1954 → Pribram 1991 → McFadden 2002/2013) holds the brain reduces rather than produces conscious content. The grid extension: less filtering corresponds to wider phase-coherent coupling to the substrate.

Test protocol

Chiral guest molecules embedded in mineral lattices of varying hardness; measure inversion barriers via temperature-dependent NMR or polarimetry. Predict: a monotone correlation between matrix hardness and inversion energy across host materials. (Specific sample size, hardness range, and statistical threshold to be set by experimentalist.)

Falsification condition

Falsified if measured chiral inversion barriers show no monotone correlation with matrix hardness across a representative set of host materials in independent replication.

Bridge and current state of evidence

The Mohs scale is empirically well-defined and routinely calibrated against indentation hardness. Chiral inversion barriers are routinely measured via Eyring/Arrhenius analysis. The Coherence claim is a cross-scale coupling between mechanical hardness and chemical inversion energy — a direct application of the signature-coupling reframing (see /predictions/signature-coupling/).

Test protocol

Pairs of impact-fragmented samples (chemically identical starting materials, controlled collision energies bracketing a predicted threshold). Measure fragment-orientation entropy and compare blinded classification accuracy above vs. below the threshold. (Specific energy thresholds and sample sizes to be set by experimentalist.)

Falsification condition

Falsified if classification accuracy of impact-fragmented sample pairs shows no threshold behaviour — i.e. only smooth monotonic decay with collision energy, without a discontinuity — across distinct material classes in blinded experiments.

Bridge and current state of evidence

Information theory and the decoherence program (Zurek) both predict information loss in irreversible interaction events. The Coherence claim is a measurable phase-information threshold for forensic reconstruction at a specific collision-energy scale.

Test protocol

Sustained low-frequency excitation of colloidal suspensions for varying exposure durations; measure stability of resulting banded structures. Compare against short-exposure controls. Predict: stability scales with exposure duration beyond the instantaneous Faraday-wave response. (Specific exposure intervals and suspension types to be set by experimentalist.)

Falsification condition

Falsified if sustained low-frequency excitation of colloidal suspensions shows no exposure-time-dependent structure formation beyond the instantaneous Faraday-wave response, in independent replication.

Bridge and current state of evidence

Kharbedia et al. (Nature Communications 2021, doi 10.1038/s41467-021-21403-0) showed that soluble (bio)surfactants can freeze Faraday-wave patterns into stable 2D-hydrodynamic crystals via surface-rigidity coupling at short timescales. The Coherence claim extends this to time-cumulative dependence in bulk colloidal suspensions.

Test protocol

Compare EIT stopped-light storage times across atomic species (e.g. Li-7, Na-23, Rb-87, Cs-133) under matched conditions. Predict: a log-log plot of τ_storage vs. atomic mass number A yields a negative slope with exponent α ≈ −1. Four conditions must hold or the measurement is uninterpretable. (1) Single platform: all species measured in the same apparatus and regime, because the published spread within Rb-87 alone (tens of microseconds to of order one second, depending on cold cloud, buffer gas, coating or room-temperature protocol) exceeds the factor of ~19 that τ ∝ m⁻¹ predicts across the entire Li-to-Cs mass range by roughly three orders of magnitude. (2) Maximum, not demonstrated, storage: most published figures record what a given experiment chose to show, not the coherence limit, so each species needs the same optimisation protocol applied to exhaustion. (3) Sign discrimination against thermal motion: at fixed temperature the thermal velocity scales as m^(−1/2), so slower heavy atoms suffer less transit-time broadening and slower diffusion out of the beam — an effect expected to lengthen storage with increasing mass. Match on thermal velocity rather than temperature, or model the transit-time contribution explicitly. (4) Separate mass from the hyperfine confound: the ground-state hyperfine splitting rises monotonically across exactly these four species (Li-7 803.5 MHz, Na-23 1771.6 MHz, Rb-87 6834.7 MHz, Cs-133 9192.6 MHz), and a larger splitting brings greater magnetic and two-photon Doppler sensitivity of the spin wave, hence faster dephasing as mass increases — a conventional mechanism with the same sign as the postulate. With only four species, mass is also near-collinear with nuclear spin, D-line wavelength and magnetic sensitivity. Model the hyperfine and magnetic contribution separately, or suppress it (magic field, dynamic decoupling), before attributing any exponent to mass as such.

Falsification condition

Falsified if EIT storage times across at least four distinct atomic species, measured in a single apparatus under matched optical thickness, thermal velocity and control-field parameters with the same maximum-storage optimisation applied to each, yield a fitted exponent whose confidence interval excludes α = −1 in independent replication. Because the postulate is quantitative, a merely negative slope is not enough: a fitted α of, say, −0.15 would refute τ ∝ m⁻¹ even while showing a negative correlation. An exponent consistent with zero likewise fails, and an exponent significantly greater than zero falsifies outright — but that last criterion applies only once matching on thermal velocity, or explicit modelling of the transit-time contribution, has removed the competing thermal effect, which on its own predicts a positive slope. Cross-platform comparisons of published values do not bear on this test in either direction.

Bridge and current state of evidence

Stopped-light via EIT is established physics, and the two 2001 demonstrations were in different species and different media — a distinction this prediction depends on. Hau et al. (Nature 397, 1999) slowed light to 17 m/s in a sodium Bose-Einstein condensate. Liu, Dutton, Behroozi & Hau (Nature 409, 490, 2001) halted and retrieved light in a magnetically trapped cloud of about 11 million sodium atoms at 0.9 µK — just above the condensation threshold, so a cold thermal cloud rather than a condensate — reporting a 1/e coherence decay of 0.9 ms. The rubidium demonstration of the same year is a separate result: Phillips, Fleischhauer, Mair, Walsworth & Lukin (PRL 86, 783, 2001) stored light for about 0.5 ms in a warm Rb vapour cell with a helium buffer gas. Second-scale storage in sodium was reached later, by Zhang, Garner & Hau (PRL 103, 233602, 2009), using condensate phase coherence in an optical dipole trap. The Compton frequency ν_C = mc²/h is standard quantum mechanics. The Coherence claim — that cross-species EIT coherence time follows the Compton-frequency ordering — is a new quantitative prediction, not derived from current EIT theory, which attributes decoherence primarily to hyperfine dephasing, collisions and thermal motion rather than to atomic mass as such. Two practical obstacles are worth stating plainly. The light end of the mass axis is close to unmeasured: dedicated Li-7 EIT storage literature is sparse, because on the lithium D2 line the excited-state hyperfine intervals (2.88, 6.00 and 9.41 MHz) are comparable to or smaller than the 5.87 MHz natural linewidth, making a clean Λ-system hard to isolate there — the splitting is well resolved on the D1 line, where Λ-schemes in Li-7 are routine — so the species where this prediction expects the longest storage is the one hardest to measure. And a naive survey of published numbers runs against the postulate rather than for it: the longest reported alkali light storage is in rubidium-87, not in a lighter species — Dudin, Li & Kuzmich (PRA 87, 031801(R), 2013) reached a 16 s 1/e lifetime in an optical lattice using a magic-valued magnetic field and microwave dynamic decoupling, against about one second in sodium. That ordering counts no more against the postulate than it would have counted for it, because it tracks platform choice and optimisation effort rather than mass — which is precisely why the single-apparatus requirement is essential rather than merely desirable.
