The Beginning of Greatness

"The organization of structure appears to follow as a hierarchical model with organization up to the scale of superclusters and filaments."

"In physical cosmology, galaxy filaments, also called supercluster complexes or great walls or "great attractors"[1][2], are amongst the largest known cosmic structures in the universe."

"The cosmological principle implies that at a sufficiently large scale, the universe is homogeneous; different places will appear similar to one another. Whilst Yadav et al have suggested a maximum scale of 260/h Mpc for structures within the universe according to this heuristic, other authors have suggested values as low as 60/h Mpc.[6] Yadav's calculation suggests that the maximum size of a structure can be about 370Mpc[3]

The Sloan Great Wall, discovered in 2003, has a length of 423Mpc,[7] which is only just consistent with the cosmological principle.

The Huge-LQG [first discovered in 2013] is estimated to be approximately 1240 megaparsecs (4 billion light-years) in its longest dimension, by 640 Mpc and 370 Mpc in the others[4] and is the largest known structure in the universe. It has a mass of \begin{smallmatrix}6.1\times10^{18} M_\odot\end{smallmatrix} (solar masses). The Huge-LQG was initially named U1.27 due to its average redshift of 1.27, and is located in the sky in the constellation of Leo

The Huge-LQG is three times longer than, and twice as wide as is predicted possible according to these current models, and so challenges our understanding of the universe on large scales."[3]

The above quotes were taken from a selection of interrelated wikis.



“The realm of ashen dreams like the world,
Where there’s my rule
Cold lonesome dusk roams like a shadow there
In the world of mortal ones the life is vain
The race of men is weak and blind
Their hearts can feel the pain,
But they can’t understand the secret…”
