That's kind of a crappy blog post. It talks about "scientists" knowing something but dosn't even say who they are or where they work, let alone give us a citation. They do link to this more detailed article though. I love that they discovered this motion based on soemthing called the "Sunyaev-Zel'dovich (SZ) effect."

The Hubble constant is something like 55 km/sec/megaparsec. Let's assume that this is happening 25 billion light years away (we know some quasars that are further away) - so that's about 7.5 megaparsecs. Which works out to 400 km/sec.
Which, given my low precision and vague memories of these values, is oddly close to the reported speed these things are moving. Interesting.

cobbling together things:
Before that point, the universe was too hot for atoms. So the universe was a soup of protons and neutrons and electrons all whizzing around. And light couldn't get through the fog of electrons. If you and I were somehow there, and I shone a magic flashlight at you, the beam would just get sucked up by the electrons, and you wouldn't see it. There would just be a glowing, uniform, featureless fog in every direction. Also you would vaporize, so that's funny.
Around 380000 years after the Grand Kaboom, things cooled down enough for protons to start grabbing electrons and making hydrogen atoms. So there weren't all these free, promiscuous electrons flitting about getting in the way of the light, and the universe became transparent.

Unknown unknown. We didn't know we didn't know it. The equation that unifies gravity with the other fundamental forces=known unknown.
Could someone care to explain this to me as if I were a 6-year-old child?
Well, if I've understood wiki correctly, they say it took approximately 380,000 years after the big bang for shit to cool down enough to form light and atoms. Before that everything was just sub atomic particles and plasma. No photons, can't observe. It seems they call it this moment the decoupling from the surface of last scattering, which is a rather pretty phrase if difficult to wrap one's mind around. (So....before then the universe was an invisible ball of energy-matter. Okeyly-dokely. Hard to picture, though.)

Minor armchair-physicist quibble: before the universe cooled enough to form neutral atoms, there were still photons and light, they just couldn't go anywhere— the universe was filled with conductive opaque/scattering plasma.
Perhaps if you go back farther, to an even hotter era, there was a time before which photons didn't exist as such.

It was all just a nice warm quark plasma once. Then the universe cooled and property values have never been the same.
From haltingproblemsolved's second link:
"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."
Giant, massive structures beyond the limits of the observable universe. So. Freakin'. Cool!

Bolder's Ring
When Jim Bolder flew to the Great Attractor in the Qax's captured nightfighter, what he found was astonishing. All matter in the universe was falling towards the object's massive gravity well. Even more astounding, this object and indeed the entire motion of the galaxies themselves appeared to be the work of the Xeelee, who were using the mass to create a ring of cosmic strings several million light years in diameter.posted by thatwhichfalls at 5:23 AM on September 2, 2009

Oh yeah, we can totally reverse time. You capture the quantum data of an event or thing or whatever at a moment in time, preserving the wave-form and keeping in flux in a kind of limbo-prison for quarks. It's a simple matter of computation and storage, we've got a few moons devoted to this project, so it's no bigger. Replay the quanta data and the wave-form reverses itself, eggs go unbroken, water becomes ice, you take back things you said, all of it.
Of course, it has to do with the perception of the viewer, If you're not careful, you end up with a whole live chicken in your omelet, or worse. But we've mostly got it under control with the Causality Locks. Mostly.
The official name is the Quantum Disentanglement Data Record And Retrieval Project, or QDDRR ("Quder"), but everyone around here just calls it "Save Point".

Ask An Astronomer has an article on the subject which might help explain.
(Believe me, you're not alone in the 'brain hurt' department. It's inevitable when people start throwing around analogies comparing the universe to dough and galaxies to baseballs, etc.)

Yeah, see I thought you couldn't go faster than the speed of light – Carl Sagan told me so! I'll check out your link, if I'm not back in an hour, it's cuz my brain hurts.

Hmm... so the speed of light limit applies to the motion of things within the framework of the observable universe, but not to the speed of expansion of that very framework. Interesting!

Well stated.

A 'science' article with exclamation points? really?
If there was ever a finding in the entire history of everything ever that called for exclamation points -- I'd say this was probably it.

“It was all just a nice warm quark plasma once. Then the universe cooled and property values have never been the same.”
Yeah, straight outta Compton.

thatwhichfalls: Thanks for mentioning that Stephen Baxter has already wrote about this, wrote it before it was found (although who knows why it exists)! It is good 'hard' Sci-Fi. More fascinating that we found a similar anomaly in space, I like it when reality is as difficult and mysterious as Sci-Fi. It furthers the idea that we are making it up as we go along.
