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.
The simultaneous existence of the largest-known voids and galaxy clusters requires about 70% dark energy in the universe today, consistent with the latest data from the cosmic microwave background. [5] Voids act as bubbles in the universe that are sensitive to background cosmological changes.

Artist's conception of the Giant Void and the filaments and walls that surround it. The internal clusters can also be appreciated (credit: Pablo Carlos Budassi). The Giant Void (also known as the Giant Void in NGH, Canes Venatici Supervoid, and AR-Lp 36) is an extremely large region of space with an underdensity of galaxies and located in the constellation Canes Venatici.
The universe also has vast regions of relative emptiness; the largest known void measures 1.8 billion ly (550 Mpc) across. [114] Comparison of the contents of the universe today to 380,000 years after the Big Bang, as measured with 5 year WMAP data (from 2008). [115] Due to rounding, the sum of these numbers is not 100%.
The group discovered the unfathomable supervoid that is 1.8 billion light-years across, according to Sky News.A section of space of that size would typically house 10,000 galleries.
