I wasn't referring to that snippet, but another one discussing the
evolution of "superclusters" of galaxies. The theory predicts that the
universe will ultimately come to be dominated by said clusters. The
snippet I mentioned seems to be referring to our measured velocity of
ca 600km/s in the direction of the Virgo supercluster, although that
wasn't explicitly mentioned in the article.
Re our own supermassive black hole at the heart of the Milky Way - I
assume we're in a stable orbit about that one, with the usual caveat
that its impossible to prove stability of any arbitrary n-body orbit
of course.
