Galactic Filament
In cosmology, galaxy filaments are one of the largest known structures in the universe, consisting of walls of galactic superclusters. These massive, thread-like formations can commonly reach 50/h to 80/h megaparsecs (160 to 260 megalight-years)—with the largest found to date being the Hercules-Corona Borealis Great Wall at around 3 gigaparsecs (9.8 Gly) in length—and form the boundaries between voids
Voids
These are giant spaces that separate the filaments. The Boötes void spans an area 330 million lightyears across but contains very few galaxies, making it the largest void in the known Universe.
According to a Study - KBC Void (or Local Hole) is an immense, comparatively empty region of space, named after astronomers Ryan Keenan, Amy Barger, and Lennox Cowie in which The Milky Way galaxy and our planet are located. However We are not living in a galactic void, but rather along a filament/surface of clusters -The Pisces -Cetus Filament. which is near the edge of the Local Void.
