The Origins of Dark Matter

The Milky Way has a little bit more dark matter than the rest of the universe We're like 90 dark matter and 10 other stuff. The rest of the galaxies is about 80 dark matter But it also varies with distance from the center of the galaxy Like where we are, everything between us and the center is about 50 50 dark matter  and other kinds of matter Whereas if you go further out then it starts to be overwhelmingly dark matter. And remember that the dark matter halo for the Milky Way is much bigger than the distribution of stars that goes out much much further.
