Megastructures beyond the horizon? Nah...

So a recent finding by Sasha Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Maryland, does not make sense. His team has found a group of galaxy clusters moving at an extraordinary speed towards a small patch of sky between the constellations of Centaurus and Vela. Kashlinsky calls it the "dark flow", in tribute to those other cosmic mysteries dark matter and dark energy (New Scientist, 24 January, p 50).
... One of the foundation stones of cosmology is the Copernican principle, which says that there is nothing special about our region of the universe.... There are also suggestions that the pull might be from another universe altogether. That would be good news for proponents of eternal inflation theory, which suggests that the universe should actually be composed of "mini-universes" that have bubbled off from one another.

From Amazon:
"Good writing," Gladwell says in his preface, "does not succeed or fail on the strength of its ability to persuade. It succeeds or fails on the strength of its ability to engage you, to make you think, to give you a glimpse into someone else's head."What the Dog Saw is yet another example of the buoyant spirit and unflagging curiosity that have made Malcolm Gladwell our most brilliant investigator of the hidden extraordinary.
Uh, all are pretty much must reads.
ok, one more youtube video...
