In the post I linked in my "via" it is claimed that cold dark matter also predicts more small satellite/dwarf galaxies than are actually observed (further discussed in this post ). What do you think?

I'm a physics major but I'm having difficulty reading this but I do have some remarks. Cyan is on to something, baryonic dark matter is unlikely to make up a large percentage of dark matter. Also, the "abundance" of large planets, in low orbits is generally regarded as selection bias by astronomers, because planets that are smaller and/or locked in higher orbits are simply more difficult to detect.
