Galaxy Rotation Curves
The ether framework predicts galaxy rotation curves via the Radial Acceleration Relation: g_obs = g_bar / (1 − exp(−√(g_bar/a₀))). Select a galaxy from the SPARC database to compare observations against the parameter-free ether prediction and the baryonic (Newtonian) curve.

The ether prediction uses the structural interpolating function μ_e(x) = 1 − exp(−√x) with no free parameters beyond the universal acceleration scale a₀ = 1.20e-10 m/s².
