### Neutrinos and the CMB II

It is good to see that Graham D is rather busy with his new astrophysics program. This post is just a quick reminder that Louise Riofrio's varying $c$ cosmology derives the baryonic matter fraction as

$\Omega_{b} = 1 - \frac{3}{\pi} = 4.507034%$

and we can now compare this value to fractions obtained by alternative means.
