Cosmology Predictions
UntestedSynchronism generates several testable predictions at cosmological scales. Some have already been tested (environment-dependent RAR scatter); others await analysis of existing or forthcoming survey data. Here are the key predictions, with their current status and what would falsify them.
Prediction 1: BAO Modulation
Density-Dependent BAO Peak Shifts
UntestedBaryon Acoustic Oscillations (BAO) are the imprint of sound waves in the early universe, visible as a characteristic ~150 Mpc peak in the galaxy correlation function. Standard cosmology predicts this peak position is universal.
Synchronism predicts: the BAO peak position should shift slightly depending on the local density of the survey volume. Overdense regions should show a compressed BAO scale; underdense regions should show an expanded scale. The shift is small (~0.1–0.5%) but potentially detectable with DESI survey precision.
Kill criterion: if DESI achieves sub-0.1% BAO measurements across multiple density environments and finds no modulation, this prediction is falsified.
Prediction 2: GW-DM Correlation
Gravitational Wave – Dark Matter Halo Correlation
UntestedIf both gravitational dynamics and “dark matter” effects emerge from the coherence field, then gravitational wave signals from compact binary mergers should correlate with the dark matter halo properties of their host environments.
Synchronism predicts: GW merger rates, signal amplitudes, and waveform characteristics should show systematic correlations with the estimated dark matter halo mass of the host galaxy or galaxy cluster. Mergers in high-density environments should show subtly different dynamics than those in voids.
Kill criterion: with sufficient LIGO/Virgo/KAGRA events (~1000+ well-localized mergers), a null correlation would falsify this prediction.
Prediction 3: Environment-Dependent RAR Scatter
RAR Scatter Varies with Local Density
p = 5×10⁻⁶This prediction has been tested and supported. The intrinsic scatter in the Radial Acceleration Relation depends on the environment density of the galaxy, with p = 5 × 10−6 significance.
See RAR Scatter for full details. Caveat: R² = 0.14 (86% of scatter unexplained).

The Pattern
All cosmology predictions share a common structure: the coherence function introduces environment dependence where standard models predict universality. If the coherence framework is correct, nothing in gravity is truly universal — every gravitational phenomenon carries an imprint of the local density field. This is philosophically radical but empirically testable.
