Test of Modified Gravity with JWST: Predicted Rotation Velocity Evolution Distinguishes ΛCDM, MOND, and Harmonic Curvature Models
Test of Modified Gravity with JWST: Predicted Rotation Velocity Evolution Distinguishes ΛCDM, MOND, and Harmonic Curvature Models
Concise presentation of three-way discriminating test using JWST high-redshift galaxy observations. At fixed baryonic mass, ΛCDM predicts rotation velocities decrease with redshift (less halo assembly time), standard MOND predicts constant velocities (fixed a₀), while HCM predicts 30-80% increase z=0→z=6 (higher harmonic frequency in early universe). JWST Cycle 3-4 data (2025-2027) will falsify at least two of three theories within 2 years. Represents cleanest test of dark matter vs modified gravity paradigms with binary outcomes requiring no statistical interpretation. Brief, accessible format suitable for broad physics readership. Keywords: JWST, high-redshift galaxies, falsifiable prediction, dark matter, MOND, rotation curves, cosmological evolution, modified gravity, Hubble parameter, observational test
