Voids are particularly galaxy-poor regions of space between filaments, making up the large-scale structure of the universe. Some voids are known as supervoids . In the tables, z is the cosmological redshift , c the speed of light , and h the dimensionless Hubble parameter , which has a value of approximately 0.7 (the Hubble constant H 0 = h × ...
A map of the Boötes Void. The Boötes Void (/ b oʊ ˈ oʊ t iː z / boh-OH-teez) (colloquially referred to as the Great Nothing) [1] is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing only 60 galaxies instead of the 2,000 that should be expected from an area this large, hence its name.

Cosmic voids (also known as dark space) are vast spaces between filaments (the largest-scale structures in the universe), which contain very few or no galaxies. In spite of their size, most galaxies are not located in voids. This is because most galaxies are gravitationally bound together, creating huge cosmic structures known as galaxy filaments.
While searching an unusual cold spot in space first discovered more than a decade ago, scientists have discovered what they say is the largest known structure in the universe -- a supervoid, ITN ...
