Ahat we know about dark matter:
If we have an exact formula for how neutrinos interact to create different forms of dark matter then it's not much of a big mystery. This gives us a stronger argument than "It exists because we would have a problem if it didn't."
http://www.astro.ucla.edu/~wright/neutrinos.html Wrote:D = \int (1+z) v dt = 2(c/Ho) sqrt(3*k*(1.947 K))/mc2) + ...
which gives D = 100 Mpc for mc2 = 5 eV in a critical density model with Ho = 65. Thus neutrinos can free stream out of the perturbations that make galaxies and cluster of galaxies, but will remain in the perturbations that make superclusters. Because this behavior is caused by the thermal velocity of the neutrinos, this form of dark matter is called Hot Dark Matter

The god who allows children to be raped out of respect for the free will choice of the rapist, but punishes gay men for engaging in mutually consensual sex couldn't possibly be responsible for an intelligently designed universe.
