Universe in a box: formation of large-scale structure The movie stills pictured above illustrate the formation formation of clusters and large-scale filaments in the Cold Dark Matter model with dark energy. The frames show the evolution of structures in a 43 million parsecs (or 140 million light years) box from redshift of 30 to the present epoch (upper left z=30 to lower right z=0). Click to see the full-resolution version of each panel. At the initial epoch (z=30), when the age of the Universe was less than 1% of its current age, distribution of matter appears to be uniform. This is because the seed fluctuations are still fairly small. You can download the movie as an MPEG movie: full size (10Mb), half size (1.3Mb) The same simulation but with a rotating box (3D geometry of the filaments can be appreciated better) an animated gif: half size (5Mb), quarter size (1Mb) MPEG movie: full size (9Mb) half size (1Mb)
