The Origin of Dark Matter in the Universe

Galaxies were maybe the first things that were dofined in the universe, the first kind of organization rate. We think that probably stars formed, and then they formed into galaxies,. But they all formed out of these big clouds of gas that were themselves formed by these dark matter halos. And so gas is falling from these filaments into these halos and then swirling together to form stars, which form galaxies. So i think it's really interesting to sort of see what emerges from structure in the universe. Now we have clusters of galaxies and super clusters of galaxies, and that process is still happening because we 're still fairly young in the world.
