Cosmologists think the galaxies could be heading toward a very large primeval structure
Scientists will try to figure out if all galaxy clusters are susceptible to dark flow. If so, we’d know that its cause stretches back to our universe’s beginning, lending credence to the theory that something we can’t see is exerting its gravitational force on everything we can see.

Dam!! First they come out with Dark Matter...then Dark Cloud and now new thing called Dark Flow. They haven't even figured out what the first Dark matter is actually all about. I hope they get better results in uncovering all this mystery.
It will be hard to learn more, though, since the source of the dark flow appears to be at least 46.5 billion light-years away, much farther than we can observe.
San Antonio--A widely reported press conference at last month's meeting of the American Astronomical Society left the impression that the long-standing mystery of the identity of the universe's "dark matter" had been solved. At the meeting a multi-institutional team reported that it might consist of the ordinary matter contained in MACHOs, massive compact halo objects, rather than the exotic particles some theorists favor. But as even those team members concede, the number of MACHO sightings they've now made is still too small to come to a firm conclusion about whether they can account for all dark matter.
It is suspected that at least another 40 known objects in the Solar System are dwarf planets, and estimates are that up to 200 dwarf planets may be found when the entire region known as the Kuiper belt is explored
