Not on the evolutionary scale, and certainly not on a cosmic scale. We might think we're special, but the reality is, we're a very tiny piece of a puzzle so large that our species and its history counts for nothing in the truly big picture.
The scientists deduced that whatever is driving the movements of the clusters must lie beyond the known universe.
A theory called inflation posits that the universe we see is just a small bubble of space-time that got rapidly expanded after the Big Bang. There could be other parts of the cosmos beyond this bubble that we cannot see.
In these regions, space-time might be very different, and likely doesn't contain stars and galaxies (which only formed because of the particular density pattern of mass in our bubble). It could include giant, massive structures much larger than anything in our own observable universe. These structures are what researchers suspect are tugging on the galaxy clusters, causing the dark flow.
Realize how small you, your religion, and your existence are; live life in harmony with this reality instead of inventing false drama like most of the herd in our "enlightened" society.
"Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every 'superstar,' every “supreme leader,” every saint and sinner in the history of our species lived there—on a mote of dust suspended in a sunbeam." -Carl Sagan, Pale Blue Dot, 1994
