"How do you even choose what to write about? We hardly know about the billions of civilizations there probably are. Do we center on the history of our nation? What about the undoubtedly larger nations which exist? What do you mean 'write about the history?' This history of what? Everything!?" -Struggling Author Duu'a Deci colamplaining about how hard it is to summarize the sheer scale of the Virgo Supercluster 75444 CE.
Template:Infobox:Galactic SuperclusterThe Virgo Supercluster (also called the Local Supercluster) is a large mass of over 2000 major galaxies and over 11000 dwarf galaxies. Most of it remains untouched, as even the largest empires have never come close to colonizing even a percentage of it. There are over one hundred galaxy groups (clusters of gravitationally bound galaxies analogous to the Aylothn-Sagittaria Group) in the cluster. The largest of these galaxy groups is called the Virgo Cluster. The Virgo Cluster is widely cited as the center of the structure.
Almost every known species, civilization, and individual have been in this cluster. The Virgo Cluster is so large that even the fastest estimates require almost another one million years for the known civilizations in the object to be colonized. However, based on the history of the structure, it is very unlikely that any civilization will live to colonize the entirety of the object. Anywhere from 3 billion to 550 billion sapient species have already gone extinct in the structure's past. Little indicates that any modern civilizations are any different. It is very likely that most of them will fall before the year 250,000 CE, with nothing taking their place.
Other important clusters include the Fornax Cluster (the second largest collection of galaxies in the Supercluster), the M81 group, the Leo II, Dorado, NGC 1023, and the Ursa Major Group. The cluster in itself is part of the much larger Laniakea Supercluster, a structure so large that it is impossible to grasp. Even with cutting edge technology, studying the entirety of Laniakea is difficult. It is impossible to detect civilizations so far away. Even in the much closer Virgo Cluster, without physically constructing a means to get there, detecting civilizations is almost impossible.
Large numbers of the galaxies in the cluster exist without being gravitationally bound to any one galaxy group. Most of these galaxies are only accompanied by a handful of satellites if any at all. Few of these very isolated galaxies have been settled, with most of them being too far away to even be worth it with modern technology.
