Giant superclusters being pulled towards single patch of sky, beingcalled "Dark Flow"

They're finding that giant superclusters of galaxies are flowing towards
a specific section of the sky. As I recall something like this was
brought up decades before, it was something called the Great Attractor.

Anyways, it seems like this is the second time this year that a paper
has likened the Universe to a body of fluid. The other time was when the
theory of Dark Fluid was put forward which seems to explain both Dark
Matter and Dark Energy as subsets of the same thing.

galaxy rotation, Inflation and Dark Energy

Anyways here's the new article about Dark Flow.

SPACE.com -- Mysterious New 'Dark Flow' Discovered in Space
"They discovered that the clusters were moving nearly 2 million mph (3.2
million kph) toward a region in the sky between the constellations of
Centaurus and Vela. This motion is different from the outward expansion
of the universe (which is accelerated by the force called dark energy).

"We found a very significant velocity, and furthermore, this velocity
does not decrease with distance, as far as we can measure," Kashlinsky
told SPACE.com. "The matter in the observable universe just cannot
produce the flow we measure.""
