PRESENT BY ABSENCE. “The detailed scale dependence of the temperature anisotropies in the CMB allow the total, matter and baryon density parameters to be measured precisely. However the measured typical amplitude of the fluctuations, ∆T/T ≈ 10(-5), alone provides evidence for non-baryonic DM.” (DM = dark matter; CMB = cosmic microwave background).
