36 numbered write-ups. Confirmed means the observation already ran the way BFUT required: mature high-z galaxies, the century-long rise in inferred age and reach, the downward move in H0 under more robust methods, the persistence of the Hubble tension, ALPHA-g antihydrogen fall. Testing means live data already points the same way (JWST, cosmic web, large rotating basins, S8, null WIMP searches). Untested means the specific measurement has not been done yet. Number 30 was not in the source file.
Every observer anywhere will appear near the centre of their observable universe
In BFUT, universal observer centrality is a direct consequence of the finite speed of light combined with spatial infinitude. Every observer, no matter their location in an infinite universe, will naturally appear to be near the centre of their observable universe because they can only observe events within a light-cone bounded by the speed of light.
The Mechanism
Light from distant sources takes time to reach the observer. The observable universe is therefore not centered on any special location, but rather on the observer themselves. This is identical to standing in an infinite ocean and observing a sphere of water around you from which light can reach your eyes.
Testable Prediction
No observer at any location should ever discover they are NOT near the centre of their observable universe. This is not circular reasoning. It is instead a prediction that would be falsified if any observer found themselves systematically displaced from centrality relative to the cosmic structure around them.
Contrast with ΛCDM
ΛCDM treats this as a philosophical principle (the Copernican principle) but provides no mechanism. BFUT makes it testable: finite light travel time guarantees it.
No observation at any depth will reveal a final boundary, terminal wall, or outer edge
Paper P5 derives spatial infinitude from first principles, establishing that no finite boundary can exist. Every attempt to place a boundary requires a statement about what lies beyond it—which immediately extends space further.
The Logical Argument
A finite universe requires a spatial boundary. But any boundary is itself a surface inside space, with space continuing on the other side. This creates an infinite regress. Therefore, space cannot be finite.
Observational Test
As telescopic reach improves, deeper observations should continue to reveal structure instead of encountering a final boundary or edge. Any discovery of a terminal wall, a beyond-this-nothing zone, or a limit to observable structure would falsify BFUT.
Current Evidence
JWST observations continue to reveal mature galaxies at the deepest observable distances. No boundary signature has appeared.
No observation will reveal a unique central point from which the entire universe originated
If the universe were infinite and eternal, there is no unique point from which matter originated. The Big Flare-Up was a threshold event that occurred simultaneously throughout infinite space whenever local density reached the Jeans instability threshold, not a single event at a single location.
The Prediction
Deep field surveys should show no systematic directional preference, no evidence of matter flowing outward from a central point, and no special location in the observable universe that can be identified as an origin.
Test
Galaxy orientations are random in all directions. No deep field image shows galaxies pointing away from a centre. This prediction is already supported by JWST observations.
No global wraparound repetitions or compact closed-space signature will be found
Some cosmological models (Poincaré dodecahedral space) propose that the universe is finite but topologically wrapped—like a video game where moving off one edge brings you back on the opposite side.
BFUT Prediction
No such wraparound topology will be discovered because the universe is not compact. Searches for repeated patterns, matched circles in the CMB, or ghost images of the same galaxy cluster at different distances should all return null results.
Current Status
Large-scale structure surveys have found no evidence of wraparound. The universe shows no signs of being finite and topologically closed.

Confirmed
Observable Universe Age and Size Only Revised Upward
As observational reach improves, inferred age and extent will continue to move upward
In BFUT, the universe is infinitely old. The observable universe age corresponds to the time light has been traveling to reach us, not the true age of the universe. As our observational reach extends, we see light that took longer to travel, implying an older observable universe.
The Test
Every major new instrument (JWST, Vera Rubin Observatory, Einstein Telescope) should reveal deeper structures and older galaxies than previous surveys. No reversal of this trend toward older ages should occur.
ΛCDM Constraint
ΛCDM predicts a finite universal age (13.8 Byr). Falsification would occur if observations pushed the observable universe significantly older than this (e.g., beyond 20 Byr).
The background temperature will remain approximately 2.725 K instead of showing boundary drop
Paper P7 proposes that the CMB temperature of 2.725 K is the dynamic thermal equilibrium temperature of the infinite universe in continuous fusion. This temperature should remain constant everywhere in space, at all epochs, because it reflects an equilibrium between stellar energy output and cooling.
The Mechanism
The universe is not a closed box. It is infinite. Thermal equilibrium at T = 2.725 K is maintained by the balance between radiation from billions of stars and cooling in the infinite substrate. This is not a relic from a single ancient event.
Observational Test
If the universe had a boundary or if it originated in a single Big Bang, we should observe temperature changes as we look deeper in time. Instead, measurements should continue to show T ≈ 2.725 K with only small local anisotropies from ongoing stellar activity.
Mature, fully-formed galaxies will continue to appear at greater observable distances
The ΛCDM model predicts that galaxies at very high redshift should be smaller, younger, and less organized because they are observed at earlier cosmic times. However, JWST has repeatedly found massive, morphologically mature galaxies at z > 10, inconsistent with ΛCDM timescales.
BFUT Explanation
In BFUT, high-redshift galaxies are not young. Redshift does not uniquely measure cosmic time. A mature galaxy at z = 10 is not problematic—it simply means that galaxy is at a great distance and its light is redshifted by gravitational sorting dynamics, not by expansion from a young universe.
Prediction
Future observations should continue to discover mature galaxies at higher redshifts. The surprise at finding "impossibly old" galaxies reflects a ΛCDM assumption, not a true problem for BFUT.
Current Status
JWST observations are already testing this. Multiple z > 10 galaxy discoveries support this prediction.

Cosmic Web Architecture Recurring at Greater Depth
Filaments, nodes, voids, and web-like organisation will continue at greater depth
The cosmic web is not a primordial relic scaffold created in the Big Bang. It is the natural result of gravitational clustering over infinite time. BFUT predicts that this web-like structure—filaments of galaxies, nodes of clusters, and vast voids—persists at all observable scales because it reflects the inherent tendency of matter to cluster under gravity.
The Prediction
As surveys deepen and extend to higher redshifts, the same large-scale web structure should continue to appear. No transition to a homogeneous state should be found. The cosmic web is not special to the early universe; it is a universal pattern of gravitational organization.
Increasingly large coherent basins, alignments, and organised structures will be found
Recent discoveries of galaxy superclusters (Hercules Supercluster, Shapley Supercluster) and large-scale alignments and flows suggest that structure organizing happens at very large scales. BFUT predicts this pattern continues.
Paper P9 Details
Cosmic rotations across scales show that angular momentum and rotational organization are present from planets to galaxies to clusters to superclusters. This is not accident; it reflects the universal principle that angular momentum emerges naturally from gravitational interactions.
Prediction
Future surveys should reveal coherent structures larger than currently known. Filaments wider than 100 Mpc, alignments spanning larger distances, and organized bulk flows at scales that challenge ΛCDM homogeneity assumptions.
Rotational or spin-related organisation will emerge on larger-than-conventional scales
Rotation is not confined to small scales. Paper P9 presents simulations showing that angular momentum emerges naturally from gravitational interactions and organizing principles hold across scales from atomic to galactic to cosmic.
Unexpected Scales
Evidence of systematic rotation and angular momentum structure is appearing at scales larger than conventional models predict. Galaxy clusters show bulk rotation. Superclusters show alignment patterns. These reflect the same underlying physics operating across all scales.
The Test
Search for rotation signatures and angular momentum organization at increasingly large scales. If such patterns continue to emerge at megaparsec and larger scales, this prediction is supported.
No final universal axis will emerge as a true global galaxy orientation
Some observations show local alignments in galaxy orientations (e.g., galaxies aligned with cosmic web filaments). BFUT does not deny this. However, there should be no global universal preferred axis—no direction in which all galaxies preferentially point.
Prediction
Large-scale galaxy orientation surveys should show randomness at cosmic scales even if local alignments persist. Galaxy orientations should be isotropic when averaged over sufficiently large volumes.

BFUT Simulations Reproduce Structure Without Dark Sectors
N-body simulations using BFUT assumptions will reproduce large-scale structure
The simulation results cited in the synthesis paper (CD1-CD14 code deposits) demonstrate that large-scale cosmic structure forms from gravitational physics alone, without requiring dark matter or dark energy as new substances.
Key Simulations
The "Invisible Loom" simulation (Section 4.7) showed that pre-luminous matter evolution under BFUT assumptions generates the cosmic web. The "Cosmic Rotation" sequence (Section 5.7) showed that hierarchical angular momentum emerges naturally. The "Bulk Flow" simulation (Section 5.5) showed that observer bulk motion alone generates the redshift-distance relation.
Falsification Criterion
If future BFUT-style simulations fail to reproduce observed large-scale structure while ΛCDM simulations (with dark sectors) succeed, this prediction is falsified.
Recession will not remain perfectly isotropic after geometry corrections
Paper P4 proposes that apparent cosmic acceleration and isotropic recession arise from observer bulk flow of ~550 km/s combined with selection effects. If bulk flow exists, recession patterns should show directional dependence.
The Dipole
The CMB dipole indicates our Local Group has bulk motion of ~600 km/s toward the Centaurus supercluster. This same bulk flow, when not properly accounted for in supernova samples, creates an apparent acceleration dipole in the data.
Test
Detailed analysis of supernova data along different sky directions should show systematic anisotropy. Recession velocity should be higher in the direction of bulk flow and lower in the opposite direction, by amounts consistent with a ~550 km/s observer flow.

Acceleration Signal Weakens with Bulk-Flow Correction
Correcting for large-scale motion will reduce or collapse acceleration signal
The evidence for cosmic acceleration rests primarily on Type Ia supernovae luminosity distances. Paper P4 and the synthesis (Section 5.5) show that when observer bulk flow is properly accounted for, the acceleration signal is substantially reduced or disappears.
The Simulation
The "Dark Energy Illusion" simulation (Section 5.5) directly tested this. With a 550 km/s observer bulk flow, the simulation produced a strong directional dipole in apparent supernova luminosity distances. Without bulk flow, the dipole vanished. This demonstrates that acceleration may be an artifact of anisotropic sampling combined with unaccounted bulk motion.
Prediction
As supernova data is reanalyzed with proper attention to observer bulk flow and selection effects, the measured acceleration parameter will decrease, potentially becoming consistent with zero acceleration.
Different H0 measurement methods will continue to disagree
The Hubble tension is a 9% discrepancy between early-universe (CMB/Planck) and late-universe (supernovae/Cepheid) measurements of the Hubble constant. ΛCDM expects these to converge; they have not.
BFUT Explanation
In BFUT, the Hubble constant is not a true universal constant. It is an emergent statistical property of gravitationally sorted galaxy populations. Early and late measurements probe different populations with different sorting histories. They should disagree.
Paper P1 Details
Gravitational sorting as an alternative to expansion explains why recession velocity is proportional to distance (Hubble's law) without requiring universal expansion. Different measurement methods at different epochs probe different galaxy populations.
Prediction
The tension will persist. More precise measurements will not converge; instead, methods will reveal the local structure dependence of H0.
Geometry-corrected methods will produce lower H0 than standard approaches
Paper P1 proposes that local gravitational structure (nearby void, attractors) biases standard H0 measurements toward higher values. Measurements that account for local structure should yield systematically lower H0.
The Mechanism
The Milky Way is not in a typical cosmic location. It is in an underdensity (Local Void) relative to the cosmic mean. This underdensity means recession velocities in our neighborhood are higher than the cosmic average for the same distance. Standard measurements not accounting for this local anomaly overestimate the global H0.
Prediction
Measurements accounting for local voids and attractors (e.g., using gravitational lensing maps to correct for local structure) should produce H0 values closer to 67 km/s/Mpc (Planck early-universe value) than to 73 km/s/Mpc (late-universe values).
The inferred Hubble constant remains dependent on local structure and observer position
A direct consequence of gravitational sorting without universal expansion: H0 is not a true constant because it depends on the local gravitational environment of the observer.
Test Populations
Observers in galaxy clusters should measure different H0 than observers in voids. Observers near attractors should measure different H0 than observers at cosmic average density. If H0 truly were a universal constant, all observers should measure the same value regardless of location.
Prediction
H0 measurements will continue to vary depending on which galaxy sample is used. Local Structure Maps (like those from gravitational lensing) should correlate with H0 variation.
Both recession-like and counter-moving behaviours will persist at all scales
BFUT predicts persistent large-scale flows and deviations from perfect isotropic expansion even when averaged over large volumes. Some observations (e.g., Andromeda approaching us, galaxies falling toward the Centaurus attractor) show inward motion.
The Prediction
Universal expansion, if it were real, should overwhelm local motions at all distances. Instead, a mixture of recession and approach motions should persist indefinitely because there is no universal expansion, only gravitational clustering dynamics.
Scale Independence
Even at very large scales (hundreds of Mpc), mixed inward/outward motions should appear because they reflect the hierarchical structure of gravitational clustering, not the homogeneous expansion of space.
Evidence requiring dark energy will progressively reduce with corrections
The primary evidence for dark energy comes from Type Ia supernovae appearing fainter (further) than expected from ΛCDM without dark energy. Papers P2 and P4 propose that when properly analyzed (with bulk flow corrections, local structure effects, selection bias), this evidence diminishes.
Paper P2: Cosmological Constant
The cosmological constant problem—why QFT predicts vacuum energy is 10^120 times larger than observed—is resolved in BFUT by recognizing that the observed Λ is not QFT vacuum energy but rather the geometric consequence of spatial infinitude. This is a physical substrate property, not dark energy.
Prediction
As systematic effects are removed from supernova data and bulk flow is properly accounted for, the evidence for cosmic acceleration and dark energy will weaken. Future measurements may find acceleration consistent with zero.
Every particle-detector search will return null results
Fifty years of direct detection experiments (XENON, LUX, SuperCDMS, etc.) have found no evidence of dark matter particles. Paper P25 explains why: dark matter is the Spaticle field, not a new particle species.
Why Detectors Fail
Detectors search for WIMP (Weakly Interacting Massive Particle) scattering in underground crystals. The Spaticle field is the background medium of space itself. It does not interact via WIMP scattering because it is not a particle in transit through space; it is space itself.
Prediction
Every new direct detection experiment will return null results. The particle dark matter hypothesis will eventually be abandoned in favor of substrate/field explanations.
Λ will remain observationally stable across redshift
The cosmological constant Λ is often modeled as a dynamic field w(z) with an equation of state that varies over time. Paper P2 proposes instead that Λ reflects the stable equilibrium density of the Spaticle substrate, which does not evolve.
Physical Mechanism
ρs = 5.9 × 10⁻²⁷ kg/m³ is not dynamic. It is the ground-state equilibrium density of the substrate. The observed cosmological constant Λ is proportional to ρs and should therefore be perfectly stable across all epochs and redshifts.
Prediction
Precision measurements will find Λ to be invariant across redshift. No evolving dark energy equation of state will be detected.
Precision data will fail to show time-varying dark-energy equation-of-state
Some dark energy models propose that the equation of state w (ratio of pressure to density) evolves over time: w(z). This would produce detectable signatures in high-redshift supernova data. BFUT predicts no such evolution because Λ is a stable substrate property.
Test
Future precision supernova surveys should find w to be consistent with −1 across all redshifts, with no evidence of evolution. Any apparent evolution is due to systematic effects, not true cosmological evolution of dark energy.
Part of the anisotropy signal will correlate with star formation
Paper P7 proposes that CMB anisotropies arise partially from local variations in stellar and stellar nucleosynthesis activity. Regions with recent high star formation rates should have slightly higher CMB temperatures due to accumulated radiation.
The Prediction
When CMB maps are cross-correlated with star formation tracers (galaxy density, star formation rate maps), a statistically significant correlation should appear at scales corresponding to foreground superstructures.
Cleaning Approach
This correlation is not primordial. It arises from recent local activity. Removing this local component should leave residual anisotropies with different statistical properties than assuming all anisotropies are primordial.
Mild non-primordial deviations will remain in CMB data
The CMB is nearly isotropic (one part in 10^5). However, various anomalies exist: the dipole, quadrupole alignment, local anisotropies. Paper P7A predicts these mild departures will persist because they reflect real local structure, not primordial physics.
Non-Primordial Origin
These anisotropies arise from our location in the cosmic web, the local void, and the Centaurus attractor. They are not relics of initial conditions but current features of local structure.
Prediction
Statistical isotropy tests should continue to reject perfect isotropy. Various anomalies should remain. This is not a problem; it is expected in BFUT.
The effective BAO scale will vary weakly with environment
The Baryon Acoustic Oscillations (BAO) scale is often treated as a fixed primordial standard ruler. Paper P7A proposes that the effective BAO scale varies subtly with local environment because the scale reflects the density at which gravity transitions from accelerating to decelerating structure growth.
Environment Dependence
In high-density environments (clusters), the transition occurs at slightly different scales than in voids. This produces observable variation in the inferred BAO scale depending on which galaxy sample is studied.
Prediction
BAO measurements using different galaxy samples or different redshift slices should show systematic variation in the inferred scale, small but detectable with precision surveys.
Precision measurements will reveal mild residual evolution
Beyond mere environment dependence, Paper P7A predicts that the effective BAO scale evolves subtly with cosmic time (or equivalently, with redshift) due to the evolving density structure of the universe.
The Mechanism
As the universe ages, density contrasts grow. The characteristic scale at which BAO features appear should therefore shift slightly as a function of epoch. Primordial physics (acoustic waves in the early universe) would produce no such evolution.
Prediction
High-precision measurements comparing BAO at different redshifts should reveal statistically significant evolution of the effective BAO scale, inconsistent with a purely primordial origin.
Onset of strong Lyman-α absorption depends on environment
The Gunn-Peterson effect is a sharp rise in Lyman-α opacity at z > 6, interpreted as a reionization front. Paper P11 proposes instead that this is an absorption percolation threshold where absorber overlap transitions from sparse to dense.
Percolation Threshold
Along any sightline at high redshift, there are discrete absorbing systems (damped Lyman-alpha systems, Lyman-limit systems). As density increases, these systems begin to overlap, creating continuous high opacity. This is a percolation phase transition, not a global reionization epoch.
Prediction
Different sightlines should show Gunn-Peterson "onset" at different redshifts depending on absorber density along that direction. The transition is not sharp and global, but gradual and local.
Opacity scatter will correlate strongly with local structure
Following from prediction 27, Paper P11 predicts that the scatter in Lyman-alpha opacity measurements correlates with the local galaxy density and overdensity structure along different sightlines.
Test Method
Cross-correlate Lyman-alpha opacity maps with galaxy density maps from surveys. If opacity variations are tied to local structure rather than being a signature of global reionization, strong correlations should appear.
Expected Result
Sightlines through galaxy overdensities should show earlier/sharper opacity transitions. Sightlines through voids should show later/gentler transitions. This environmental dependence is predicted and testable.
Five additional masses at 26.88, 85.61, 108.19, 117.84, 139.62 GeV
Paper P19A derives substrate resonances from the condensation geometry. Beyond the known particle masses (Higgs at 125 GeV, W, Z bosons), five additional resonances are predicted at specific energies that have not yet been experimentally tested.
These are predictions made before experimental confirmation. Their discovery would support BFUT. Continued null results at these masses would constrain the framework.
Paper P16 derives the proton charge radius from substrate condensation geometry: rp = 0.8398 fm. Earlier measurements gave ~0.877 fm, newer measurements (CODATA 2018) give 0.8414 fm. Paper P16A predicts continued convergence toward the BFUT value.
Current Status
The "proton radius puzzle" (discrepancy between muonic hydrogen and electron scattering measurements) has been partially resolved by improved measurements. Further refinements should move the accepted value toward 0.8398 fm.
Prediction
Future precision measurements (especially from muonic helium and other techniques) will converge on the BFUT-derived value, bringing the proton radius puzzle to full resolution.
Bell tests will confirm substrate-predicted violation angle
Paper P19A derives quantum mechanics and the Born rule from substrate dynamics. This yields predictions about the angular dependence of Bell inequality violations in quantum entanglement experiments.
Specificity
Rather than the general prediction that Bell inequalities will be violated (already confirmed), P19A makes a specific prediction about the angle at which maximum violation occurs, derived from substrate geometry.
Test
Precision Bell tests varying the measurement angle should find maximum violation at the angle predicted by substrate condensation geometry, not just any angle consistent with quantum mechanics.
ALPHA and AEGIS programs will confirm identical gravity
Paper P16A predicts that antihydrogen falls under gravity at exactly the same rate as hydrogen. This tests whether antimatter responds to gravity identically to matter. Current experiments (ALPHA, AEGIS) are approaching sensitivity to detect any difference.
BFUT Prediction
No difference will be found. Antimatter is produced by the same substrate condensation mechanism as matter, just with opposite internal circulation (charge). Gravitational response depends on mass-energy, not on this circulation direction.
Current Status
Experiments are reaching the precision needed to definitively test this. ALPHA is constraining gravity-violating differences to better than 10% of g.
The ground-state energy of hydrogen and the stability of atoms against collapse depend on a balance between the Coulomb attraction and quantum kinetic energy. Paper P16 shows this balance is exactly right given ρs = 5.9 × 10⁻²⁷ kg/m³.
The Constraint
If ρs were increased by ~90% (to 11 × 10⁻²⁷ kg/m³), the quantum of action ħ would decrease, changing the Bohr radius and destabilizing atoms. This provides a fundamental upper bound on possible substrate densities.
Prediction
No local modification of spacetime (even in principle) could increase substrate density to ~10 × 10⁻²⁷ without causing atomic destabilization. This is a deep consistency check on the theory.
No confirmed gravitational wave events from isolated mergers
Papers P6 and P28 propose that black holes are gravitational vortices, not singularities. This affects their merger signatures. Additionally, isolated compact object mergers (two neutron stars or black holes meeting in empty space far from galaxies) should be vanishingly rare in BFUT because there is no primordial black hole population and compact objects form primarily in galactic/cluster environments.
Current Status
LIGO/Virgo gravitational wave detections have found mergers, most appearing to be in galactic or cluster environments (inferred from source location). No confirmed isolated merger in empty space has been found.
Prediction
All high-confidence gravitational wave events will be associated with galactic or cluster environment. No clean isolated binary mergers far from galaxies will be confirmed.
Number of fermion generations fixed at 3 by condensation symmetry
The Standard Model has three generations of quarks and leptons. Why three and not two or four? Paper P29 proposes that three is the inevitable result of the 3+e condensation symmetry that creates the proton. The 3+e topology necessarily produces exactly three independent fermion families.
The Mechanism
The three-fold rotational symmetry of the proton condensation, combined with bifurcation dynamics, generates three independent fermion modes. A fourth generation cannot form without violating the underlying condensation geometry.
Prediction
No fourth generation of quarks or leptons will be discovered. The three-generation structure of the Standard Model is not accidental but geometrically necessary.
S8 suppression will appear across all weak-lensing surveys
The S8 tension: weak gravitational lensing surveys (KiDS, DES, Euclid) consistently measure S8 lower than ΛCDM predictions from CMB. BFUT Paper P13 explains this as reflecting suppressed structure growth in the late universe, not a true tension but evidence for a different structure formation history.
The Prediction
The S8 deficit will appear consistently across all independent weak-lensing surveys (KiDS, DES, Euclid, LSST when complete). No future survey will resolve this to agreement with ΛCDM predictions. The suppression is not measurement error; it is real physics.
Current Status
Multiple surveys already show this deficit. It is one of the most robust observational tensions with ΛCDM.
