=== End of Greatness ===
The ''End of Greatness'' is an observational scale discovered at roughly 100&nbsp;[[Megaparsec|Mpc]] (roughly 300 million light-years) where the lumpiness seen in the large-scale structure of the [[universe]] is [[wikt:homogeneous|homogenized]] and [[isotropic|isotropized]] in accordance with the [[cosmological principle]].<ref name=Kirshner /> At this scale, no pseudo-random [[fractal]]ness is apparent.<ref>Natalie Wolchover, [https://news.yahoo.com/universe-isnt-fractal-study-finds-215053937.html "The Universe Isn't a Fractal, Study Finds"], LiveScience.com, 22 August 2012.</ref>

The [[supercluster]]s and [[Galaxy filament|filaments]] seen in smaller surveys are [[random]]ized to the extent that the smooth distribution of the universe is visually apparent. It was not until the [[redshift survey]]s of the 1990s were completed that this scale could accurately be observed.<ref name="Kirshner">{{cite book |author=Kirshner |first=Robert P. |url=https://archive.org/details/extravagantunive00kirs |title=The Extravagant Universe: Exploding Stars, Dark Energy and the Accelerating Cosmos |date=2002 |publisher=Princeton University Press |isbn=978-0691058627 |page=[https://archive.org/details/extravagantunive00kirs/page/71 71] |language=en-us |url-access=registration}}</ref>
