The Virgo Cluster and the Local Group of Galaxies
Analysis of the dynamics of the Local Supercluster has provided a picture of
how the enormous mass of the Virgo Cluster acts gravitationally on the galaxies
and galaxy groups around it. As a result, the value of the Virgo Cluster mass
and the motion of the Local Group with respect to it (the Virgo-centric flow at
the location of our small family of galaxies) seems to indicate that the Virgo
Cluster is massive enough to slow down and eventually stop our cosmological
recession from it, and then accelerate the Local Group member galaxies toward
the central region of the Local, or Virgo Supercluster of Galaxies.
Consequently, it appears probable that the Local Goup will finally fall and
merge into, or be "eaten" by the Virgo Cluster.
An estimate of this effect will be given below.
