Maybe not. I am better at thinking about the migration paths of elk than the migration paths of galaxies. But it is a stunning video. Laniakea means "immeasureable heavens" in Hawaiian. More here.
I find it interesting that they still talk about the "Great Attractor". When I was cutting my teeth on cosmology, well, everything in the neighborhood was falling toward the Virgo Supercluster, which was falling toward the Great Attractor.
I feel like a bit of a Hoyle steady stater troglodyte nowadays--frankly, I do not believe in dark matter or dark energy. I consider it a sign that popular cosmological theories are missing something very basic. How many angels can dance on the head of a pin, anyway?
