A team of the British, American, and Hungarian astronomers have reported that the universe is crossed by at least 13 'Great Walls', apparent rivers of galaxies 100Mpc long in the surveyed domain of seven billion light years. They found galaxies clustered into bands spaced about 600 million light years apart that stretch across about one-fourth of the diameter of the universe, or about seven billion light years. This huge shell and void pattern would have required nearly 150 billion years to form, based on their speed of movement, if produced by the standard Big Bang cosmology.
Discovery of the Great Walls of galaxies and filamentary clumping of galactic mater has greatly upset the traditional notion that galactic matter should be uniformly distributed. If the universe began with a Big Bang 13.7 billion years ago, the awesome size of these large-scale structures is baffling because there is apparently not sufficient time available for such massive objects to form and to become organized.
