  2. Void (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Void_(astronomy)

    There exist a number of ways for finding voids with the results of large-scale surveys of the universe. Of the many different algorithms, virtually all fall into one of three general categories. [27] The first class consists of void finders that try to find empty regions of space based on local galaxy density. [28]

    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.

  4. Milne model - Wikipedia

    en.wikipedia.org/wiki/Milne_model

    The Milne universe is a special case of a more general Friedmann–Lemaître–Robertson–Walker model (FLRW). The Milne solution can be obtained from the more generic FLRW model by demanding that the energy density, pressure and cosmological constant all equal zero and the spatial curvature is negative.

    The chronology of the universe describes the history and future of the universe according to Big Bang cosmology.. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.

  9. Local Void - Wikipedia

    en.wikipedia.org/wiki/Local_Void

    The Local Void is a vast, empty region of space, lying adjacent to the Local Group. [3] [4] Discovered by Brent Tully and Rick Fisher in 1987, [5] the Local Void is now known to be composed of three separate sectors, separated by bridges of "wispy filaments". [4]
