The thing about the ratio of baryonic to dark matter is that nucleosynthesis in the big bang would have gone differently if there was much more baryonic matter around than the amount currently estimated - for example if there was enough to make the universe come out flat, as it apparently is to high precision, and no dark matter needed.
So we need something non-nuclear-interacting for that reason alone. (Or so I'm told.) -- You received this message because you are subscribed to the Google Groups "Everything List" group.
