JWST Early Galaxies

Observation: Massive, structured galaxies (10¹⁰–10¹¹ M⊙) at z > 10 appear only 300–400 Myr after the Big Bang.

ΛCDM issue: Standard hierarchical growth cannot form such systems fast enough without extreme fine-tuning.
EFC interpretation: Gravity emerges from entropic gradients within the energy-flow field. Early high-density zones couple thermodynamically, accelerating structure formation. Dynamic c(z) and compressed thermodynamic time τ resolve the time-budget problem.
Predicts higher metallicity and mature morphologies at z > 10.
No need for particle dark matter.
Flat entropic halo profiles instead of NFW.
Falsifiable through JWST deep-field mass–luminosity relation and DESI fσ₈ evolution.

BAO + Growth (fσ₈)

EFC-D modifies large-scale energy-flow dynamics and predicts subtle deviation in growth rate compared with ΛCDM at z ≈ 0.5–1.5. Upcoming DESI data (2025-26) will test this directly.

“Model-independent BAO–SN Ia consistency test reveals redshift-dependent tension (z ≈ 1), consistent with dynamic flow predictions in EFC-D.”

CMB Power Spectrum

EFC-D reproduces the overall acoustic scale but expects phase shifts in higher-order multipoles due to dynamic energy-flow coupling. Future CMB-S4 data will constrain this.

Integrated Sachs–Wolfe Effect

Both ΛCDM and EFC predict ISW correlations, but EFC allows small-scale temporal phase variation linked to entropy flow. Current Planck × LSS cross-correlations remain consistent with EFC.

Hubble Tension (H₀)

Ongoing tests (JWST/SH0ES). EFC interprets the discrepancy as local-to-global entropy-gradient variance, not new physics in the expansion rate. Results pending.

Dark-Energy Evolution w(z)

DESI Y5 will measure potential deviation from w = −1. EFC expects w(z) to vary dynamically with large-scale energy-flow gradients.

Galaxy Rotation Curves

EFC-S produces flat rotation curves without particle dark matter, via distributed entropic tension. SPARC data remain consistent within uncertainties.

Weak-Lensing Shear

EFC-D retains correct shear amplitudes while adjusting halo-mass mapping through energy-flow coupling. KiDS/DES-Y3 show compatible results.

Small-Scale Structure (LSST / Euclid)

Future data will probe dwarf-galaxy mass spectra. EFC predicts smoother, lower-contrast clustering than ΛCDM due to continuous energy-flow fields.

Scheduled Observational Tests (2025–2029)

These ongoing and upcoming missions will directly test Energy-Flow Cosmology predictions:

DESI Y5 (2026): Final BAO + growth data → tests EFC-D dynamic w(z).
JWST Cycle 4 (2025–26): Early galaxy structure → tests time-compression and entropy coupling.
Euclid + Rubin LSST (2026–27): Weak-lensing and small-scale clustering → tests halo smoothness in EFC-S.
CMB-S4 (~2029): High-ℓ phase tests of energy-flow coupling in EFC-D.
H₀ Calibration (SH0ES + JWST): Tests entropy-gradient variance as cause of H₀ tension.
