A cosmic void, often referred to simply as a “void,” is a vast and empty region in the universe that contains very few galaxies and other cosmic structures. These voids are the opposite of dense regions like galaxy clusters or superclusters. Cosmic voids are characterized by their low matter density and are essentially large, empty spaces in the cosmic web of the universe.Voids are a fundamental part of the large-scale structure of the universe and are essential for understanding its overall structure and organization. They can vary in size, with some voids spanning hundreds of millions of light-years across. The formation and distribution of cosmic voids are influenced by the complex interplay of various cosmological factors, including dark matter and dark energy.
