Local Void

The Local Void, sometimes also called the Northern Local Supervoid is a region of space largely devoid of matter. It forms the space between the Coma Supercluster and the Laniakea Supercluster, with its southern tip touching the outer filaments of the Perseus-Pisces Supercluster. The Local Void is an immense expanse. Though precise definitions of its extent and shape are disputed, it is thought to be between 150 and 300 million lightyears across. Even very massive black holes would only allow ships to jump, at most, about 10% of the distance across the Void.

Geography

The Local Void is divided into four regions: the Cycladean Bridge, the Ionian Bridge, The Center, and The Four. Isolated dwarf galaxies, globular clusters, and rogue stars exist outside these clusters, but these form the bulk of the matter found in the Void. The Cycladean Bridge runs from the Coma Cluster to The Center; the Ionian Bridge runs from the Leo Cluster to The Center. Both the Leo and Coma clusters lie in the Coma Supercluster, across the Void from Laniakea. The Four is an isolated group of giant spiral galaxies in the north-central part of the Void, millions of lightyears from anything.
