Question 1

Cosmological constant problem

Accepted Answer

u_vac=ρₛc², with empty substrate modes contributing no physical condensation energy.

Question 2

QFT vacuum-energy discrepancy

Accepted Answer

One physical substrate replaces the multiple independent vacuum-field contributions used in the conventional sum, while unexcited modes carry no condensation energy.

Question 3

Seeliger paradox / divergent summed gravity

Accepted Answer

g_total=Σ_i g_i exp(−r/R_domain,i), giving finite contributions from finite deformation domains.

Question 4

Infinite gravitational range

Accepted Answer

R_d=[3M/(8πρₛ)]^(1/3) gives every source a finite deformation domain.

Question 5

Galaxy missing gravity

Accepted Answer

The dark matter effects equation (DME) introduces the substrate-derived acceleration scale aₛ=c√(Gρₛ/3).

Question 6

Deep-galaxy mass-velocity relation

Accepted Answer

v⁴≈GMaₛ follows from the low-acceleration DME limit.

Question 7

Weak-lensing excess

Accepted Answer

The same DME and substrate scale are applied to the KiDS-1000 stacked lensing data.

Question 8

Dark-matter particle requirement

Accepted Answer

The additional gravitational response is represented by substrate deformation and entrainment, with no dark-matter particle parameter.

Question 9

Proton-electron hierarchy

Accepted Answer

m_e_vss=mₚ/(6π⁵) provides a geometric mass relation.

Question 10

Planck-constant origin

Accepted Answer

ħ_vss=mₚcrₚ/(πR₀) connects the BFUT-derived ħ_vss to the condensation geometry.

Question 11

Fine-structure constant

Accepted Answer

α_vss is linked to the BFUT condensation and ħ_vss derivation chain.

Question 12

Strong-coupling geometric scale

Accepted Answer

αₛ_vss is related to condensation geometry through αₛ_vss∝BR₀⁴/A.

Question 13

Universal speed-limit origin

Accepted Answer

c_vss=√(Kₛ/ρₛ), with Kₛ=ρₛc_vss², identifies c_vss with the substrate reorganisation limit.

Question 14

GW/photon speed equality

Accepted Answer

Both are substrate disturbances and share the same maximum propagation rate c.

Question 15

Relativistic time-dilation structure

Accepted Answer

c²=v_internal²+v_grav²+v_spatial² and η=dτ/dt= c_s/c₀ provide a common propagation-budget description.

Question 16

Singularity divergence

Accepted Answer

The causal limit gives finite R_max=GM/c² and ρ̄_max=3c⁶/(4πG³M²), while the condensation functional excludes zero-radius condensation.

Question 17

Quantum/classical regime connection

Accepted Answer

The carrier-field formulation supplies a common substrate description whose settled limits reproduce the classical gravitational regime.

Question 18

S8 tension

Accepted Answer

Rotational-collapse suppression gives a 6.2% S8 deficit in the P13 proof-of-concept simulation.

Question 19

Hubble tension

Accepted Answer

BFUT replaces a single universal expansion interpretation with gravitational sorting and observer-dependent sampling; P1 reports r=0.675 for the sorting model.

Question 20

Early-structure timing problem

Accepted Answer

An eternal substrate removes the finite-age formation constraint used in a finite-origin cosmology.

Question 21

Horizon problem

Accepted Answer

An infinite, eternal substrate removes the requirement that all observed regions were once in causal contact after a finite beginning.

Question 22

Flatness problem

Accepted Answer

Spatial infinitude removes the finite-origin curvature-dilution requirement associated with inflation.

Question 23

CMB temperature origin

Accepted Answer

T=(u_CMB c/(4σ))^(1/4) gives 2.725 K from the measured CMB energy density.

Question 24

Cosmological acceleration / dark-energy interpretation

Accepted Answer

Observer bulk flow and gravitational sorting supply a mathematical route to apparent acceleration without a separate dark-energy term.

Question 25

ISW anomaly interpretation

Accepted Answer

Local Spaticle field temperature variations supply a mathematical contribution to the observed ISW signal.

Question 26

Galaxy-scale lensing and rotation consistency

Accepted Answer

The same aₛ and substrate framework are used across SPARC rotation curves and KiDS-1000 lensing.

Question 27

Finite-range correction to Newtonian gravity

Accepted Answer

The exponential carrier solution gives g/g_N=e^(−x)(1+x), with x=r/R_eff, and approaches Newtonian gravity as x→0.

Question 28

Dark matter as a particle

Accepted Answer

BFUT interprets the additional gravitational effect as organised substrate deformation and entrainment. The question becomes a gravitational-response problem, not a requirement for a new particle.

Question 29

Dark-energy requirement

Accepted Answer

BFUT interprets apparent acceleration through observer bulk flow and gravitational sorting, without introducing a separate dark-energy component.

Question 30

Hubble tension

Accepted Answer

The observed Hubble relation is treated as an emergent statistical property of gravitationally sorted matter. Different sampled populations can produce different inferred slopes.

Question 31

Horizon problem

Accepted Answer

An infinite and eternal substrate does not require a finite-origin epoch in which distant regions were brought into causal contact.

Question 32

Flatness problem

Accepted Answer

Spatial infinitude removes the need for inflationary curvature dilution to explain a globally near-flat observable geometry.

Question 33

Early galaxy formation timing

Accepted Answer

Structure can develop in an eternal universe with no fixed finite age measured from a Big Bang origin.

Question 34

CMB relic interpretation

Accepted Answer

The CMB is treated as dynamically maintained thermal equilibrium radiation continuously supplied by stellar processes.

Question 35

Lithium problem

Accepted Answer

Steady-state nucleosynthesis in an ongoing stellar-processing universe supplies an alternative account of primordial lithium abundance.

Question 36

S8 tension

Accepted Answer

Rotational support during structure formation reduces inferred clustering amplitude, while the lensing inference pipeline itself is shown to be model-sensitive.

Question 37

Low-redshift versus CMB growth mismatch

Accepted Answer

BFUT attributes the low-redshift suppression pattern to rotational structure dynamics and questions whether a single ΛCDM growth history is the unique interpretation.

Question 38

S8 methodological sensitivity

Accepted Answer

The P13 simulations show that defensible analysis choices can shift or broaden recovered S8 while holding the underlying synthetic shear field fixed.

Question 39

Weak-lensing excess

Accepted Answer

BFUT uses the same substrate-derived gravitational response that fits galaxy dynamics to interpret weak-lensing observations.

Question 40

Ultra-diffuse and low-dark-matter galaxies

Accepted Answer

These systems are treated as tests of the substrate-response model, including cases where the observed dynamics are close to the stellar component alone.

Question 41

Merger mass-distribution interpretation

Accepted Answer

Merger morphology is interpreted through redistribution and entrainment of substrate-associated gravitational response, allowing lensing and visible matter to be compared directly during interaction.

Question 42

Cosmic redshift interpretation

Accepted Answer

Redshift is treated as a Doppler/gravitational-sorting effect through a static substrate, so photon propagation does not require stretching of the substrate itself.

Question 43

CMB and large-scale structure as separate relic epochs

Accepted Answer

BFUT places them in one continuously existing substrate, with the CMB maintained dynamically and large-scale structures forming within the same persistent environment.

Question 44

Black-hole singularity problem

Accepted Answer

BFUT retains the observed compact-object phenomena while interpreting the interior as finite organised substrate compression.

Question 45

Black-hole information problem

Accepted Answer

The finite-core, permeable-boundary picture provides a route for information to remain encoded in substrate deformation and to relax outward.

Question 46

Hawking-radiation mechanism

Accepted Answer

BFUT does not use the standard singularity-plus-event-horizon pair-creation mechanism; it substitutes finite carrier relaxation emission from the compressed substrate.

Question 47

Need for inflation as the unique early-universe solution

Accepted Answer

BFUT's infinite, eternal substrate provides alternative explanations for horizon, flatness and early-structure timing without an inflationary origin event.

Question 48

Universal expansion as the only interpretation of cosmic acceleration

Accepted Answer

BFUT treats directional observer motion and gravitational sorting as physical alternatives that can generate apparent acceleration.

Question 49

Unique ΛCDM interpretation of low-redshift observables

Accepted Answer

BFUT argues that SZ, weak lensing, redshift-space distortions, ISW and related observables can have substrate-based interpretations that do not depend on one universal ΛCDM growth narrative.
