We live in the Laniakea supercluster. Galaxies including the Milky Way are being pulled toward the "Great Attractor" in its center.
Two questions (note that the answer to one can be used to derive the answer to the other):
- How fast are we moving toward the Great Attractor?
- What is the escape velocity of the Laniakea supercluster? That is, assume it is the only supercluster in the universe.
As in this question I understand that the answer depends on uncertain data. A reasonable guess is perfectly fine for me.
