Galaxy Curve Plotter
Select a SPARC galaxy and compare observed rotation curves with Newtonian (baryons only) and Synchronism predictions. The gap between Newtonian and observed is what ΛCDM calls “dark matter.”
What You're Seeing
The dashed line is what rotation curves should look like with only visible matter (stars + gas). The blue dots are what we actually observe. The gap is the “dark matter problem.”
Synchronism's violet curve fills the gap using C(ρ) with γ = 2 (uncorrelated stars) — no dark matter particles needed. The coherence function adds an effective mass component from the density field itself.
Note: Curves shown are simplified models for illustration. Actual SPARC fits use full surface brightness profiles and mass-to-light ratios. See the research data for precise fits.
