Dark Matter Streams - Ralf Kähler

Formation of a large cluster of galaxies from the early Universe until the present day. The expansion has been scaled out to better show the gravitational collapse into filamentary structure, where individual galaxies form and fall in to the cluster’s center, where the filaments intersect. This region is comparable to a large cluster of galaxies in the local Universe, such as the Virgo or Coma Clusters.
