Despite this scientists think it is representative of the entire cosmos. Plotting them in a three-dimensional map has produced the largest region ever mapped. The main features of the map are superclusters of galaxies. Galaxies, star systems like our own, occur in clusters ranging from a few dozens to a few thousands of galaxies. These clusters are themselves grouped into galactic superclusters which can be seen on the map.
Astronomers are especially interested in the voids between the superclusters.
An important aspect of the map is the ratio of the size of the superclusters to the size of the voids. This is believed to be something fundamental about the make-up of the universe. The map contains encoded information about the matter that makes up the universe. We can use it to determine what the dark matter is as well as the fate of the universe itself. From the distribution of matter in the map scientists think that the universe will expand forever.
