M1 - 2 - Iso- vs. Anisotropic Space

Research survey spurred by "the isotropy of space".

Galactic Filaments are the largest observed structures in the Universe.  The Great Sloan Wall measures 1,370,000,000 Light Years (Light travels at 299,792,458m/s) Long.  In between these filaments are Voids, huge volumes of space devoid of almost all mass.  


The variable distribution of mass in the Universe is illustrated by the recent observation (1978) that the Local Group of Galaxies, including our Milkyway (and its potential super-huge blackhole) are all actually being drawn, towards a common region of space so dense that it is known at the Great Attractor. 


The distribution of mass or "luminous matter" in the universe is more like a foam that does not violate the Cosmological Prininciple (Viewed on a sufficiently large scale, the properties of the Universe are the same for all observers.' (Keel 2007)


This in image from one section of a 10,000,000,000 particle simulation by the Max Planck Institute for Astrophysics.  

The 
Millennium Run used more than 10 billion particles to trace the evolution of the matter distribution in a cubic region of the Universe over 2 billion light-years on a side. It kept busy the principal supercomputer at the Max Planck Society's Supercomputing Centre in Garching, Germany for more than a month. By applying sophisticated modelling techniques to the 25 Tbytes of stored output, Virgo scientists have been able to recreate evolutionary histories both for the 20 million or so galaxies which populate this enormous volume and for the supermassive black holes which occasionally power quasars at their hearts. By comparing such simulated data to large observational surveys, one can clarify the physical processes underlying the buildup of real galaxies and black holes. (
