[B][URL=http://www.iucaa.in/Saraswati-General.html]“Saraswati”[/URL]- one of the most massive large-scale structures in the Universe
A team of astronomers from the Inter University Centre for Astronomy & Astrophysics (IUCAA), and Indian Institute of Science Education and Research (IISER), both in Pune, India, and members of two other Indian universities, have identified a previously unknown, extremely large supercluster of galaxies located in the direction of constellation Pisces. This is one of the largest known structures in the nearby Universe, and is at a distance of 4,000 million (400 crore) light-years away from us....
Large-scale structures in the Universe are found to be hierarchically assembled, with galaxies, together with associated gas, and dark matter, being clumped in clusters, which are organized with other clusters, smaller groups, filaments, sheets and large empty regions (“voids”) in a pattern called the “Cosmic web” which spans the observable Universe.
Superclusters are the largest coherent structures in the Cosmic Web. A Supercluster is a chain of galaxies and galaxy clusters, bound by gravity, often stretching to several hundred times the size of clusters of galaxies, consisting of tens of thousands of galaxies. This newly-discovered ‘Saraswati’ supercluster, for instance, extends over a scale of 600 million light-years and may contain the mass equivalent of over 20 million billion suns.
When astronomers look far away, they see the Universe from long ago, since light takes a while to reach us. The Saraswati supercluster is observed as it was when the Universe was 10 billion years old.
The long-popular “Cold dark matter” model of the evolution of the Universe predicts that small structures like galaxies form first, which congregate into larger structures.[U] Most forms of this model do not predict the existence of large structures such as the “Saraswati Supercluster” within the current age of the Universe. The discovery of these extremely large structures thus force astronomers into re-thinking the popular theories of how the Universe got its current form, starting from a more-or-less uniform distribution of energy after the Big Bang.[/U]

В заявленном понятно существование массивных образований древности в виду изначальной иерархии в распределении материи.
