Editing Virgo Supercluster (section)

===Large-scale dynamics===
Since the late 1980s it has been apparent that not only the [[Local Group]], but all matter out to a distance of at least 50 [[Parsec|Mpc]] is experiencing a bulk flow on the order of 600&nbsp;km/s in the direction of the [[Norma Cluster| Norma Cluster (Abell 3627)]].<ref name="plionis91">

Lynden-Bell et al. (1988) dubbed the cause of this the "[[Great Attractor]]". The Great Attractor is now understood to be the center of mass of an even larger structure of galaxy clusters, dubbed "[[Laniakea Supercluster|Laniakea]]", which includes the Virgo Supercluster (including the Local Group) as well as the Hydra-Centaurus Supercluster, the Pavo-Indus Supercluster, and the Fornax Group.

The Great Attractor, together with the entire supercluster, is found to be moving toward [[Shapley Supercluster]], with center of [[Shapley Attractor]].<ref>{{Cite web|url=http://www.universetoday.com/113150/what-is-the-great-attractor/|title = What is the Great Attractor?|date = 14 July 2014}}</ref>
