Baryon Fraction

Effects of raising the baryon fraction. Raising the baryon fraction by lowering the cold dark matter density at fixed baryon density in a flat &Lambda universe with fixed Hubble constant (WMAP7 cosmology). That the third peak is not much lower than the first peak is good evidence that dark matter exists.
