What movement describes the Local Group being pulled toward the Virgo Cluster's center?
Answer
Virgocentric flow
Due to the profound gravitational dominance exerted by the massive Virgo Cluster, the Milky Way's Local Group is subject to a net inward motion toward the cluster's core. This large-scale streaming motion is specifically termed the Virgocentric flow. This movement means that the Local Group is not receding from Virgo at the rate expected solely based on the universe's overall expansion. In fact, the gravitational influence from Virgo is significant enough to noticeably counteract the expansion, estimated to slow the Local Group's recession velocity by roughly ten percent.
