Randomized trial tests a conditional framework for galactic acceleration scale, indicating consistency with SPARC data.

This research examines a new framework to test the radial acceleration relation and its consistency with galaxy data.
Developed a conditional horizon-readout protocol for measuring acceleration scales.
Tested the framework with SPARC data from 93 galaxies, analyzing 2060 radial points with fixed mass-to-light ratios.
Utilized maximum likelihood methods to evaluate model fit and parameter uncertainty.
The acceleration scale was determined as aRAR = (1.213 ± 0.084)×10−10 m s−2 with consistency to theoretical predictions.
The interface coefficient was found to be ν̂ = 1.011 ± 0.071, demonstrating minimal deviation from the expected value.
The constructed model provided a statistical alignment with observed galaxy data, confirming established relationships.
