Cosmic void
Cosmic void is a large region of space with a significantly lower density of galaxies compared to the cosmic average. It forms part of the large-scale structure of the universe.
Cosmic voids are discussed in cosmology, large-scale structure studies, and astrophysics.
Status
Cosmic voids are identified through galaxy surveys and statistical analyses of matter distribution. Their size, shape, and evolution are modeled to constrain cosmological parameters and structure formation theories.
