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.

[0804.1588] Dark Fluid: Towards a unification of empirical theories of
galaxy rotation, Inflation and Dark Energy
http://arxiv.org/abs/0804.1588

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.""

I guess this is on a ~slightly~ "smaller" scale than the current
suggestion.

The Universe can very much be modelled as a fluid, it does not mean
there is an underlying fluid... other than the matter we see and
measure.

Such a motion could result from our "stationary" position actually
moving away from "The Great Attractor". If all matter were generally
moving towards a single point, at a more-or-less constant velocity,
*we could not observe it*. No relaive motion.

Space aliens in the Star Nebula made an LHC and punched a hole in
spacetime. Everything is draining. Our only hope is to punch another
hole ourselves to balance the flow. Now, you explain it to me.

Hint: curve fitting is not the same as science. If it were, we'd
still be enjoying epicycles.

They should've called this one the "Great Celestial Drain". It looks
like somebody pulled the Great Celestial Stopper on our Universe and now
we're flowing down the drain.

I say where there is smoke, there is fire. Or in this case, where there
is flow, there is fluid. We're living in a big fish bowl, probably quite
literally!

I say it's a big clue to something that might actually be underneath. If
it walks like a duck ..., etc.

Even the (in)famous Bullet Cluster is being sucked down this Cosmic
Drain Pipe.

Diffraction shows that matter fills all of space to some extent.
This obviates "something else" and "underneath".

Think about what you are saying. We little primates on our
planet in one solar system in one galaxy in one supercluster sees
the whole rest of the Universe moving towards a Great Attractor,
but we obviously aren't moving, or moving towards the Attractor
at least.

How stupid can we be?

"In physical cosmology, dark flow is the collective velocity of galaxy
clusters over at least a billion light years that is independent of
the universe's expansion and does not change with distance."
http://en.wikipedia.org/wiki/Dark_flow

This reminds me of the anomalous acceleration of the Pioneer
spaceprobes, which apparently doesn't change with distance either.

Yup, we're finding all kinds of anomalous aspects about gravity now
that we're actually "getting out there". I'm sure we're going to find
even more differences between our current understanding of gravity and
what it's actually like. Our current understanding of gravity is based
mainly on observations located on Earth and in the Solar System. It's
a bit like our knowledge of the world beyond what was explored, where
it was noted on maps, "Here there be Monsters". :-)

At a macro level, yes, matter fills all of space. But it doesn't fill
it at the same density in all parts of space (i.e. voids vs.
clusters), nor at the micro level. The only thing that fills *all* of
space equally is space. An analogy would be to say salt fills all of
the oceans. Salt doesn't really fill all of the oceans, water does. It
rides around all over the oceans in the water, goes to most places
that the water does. Matter could just be the salt riding around in
the ocean of the Universe. If this sounds like 3-D M-brane World of
Superstring/M-Theory, or the Space-Time loop blocks in Loop Quantum
Gravity, or a variation of the Aether, then so be it.

As for whether light diffraction shows that only matter fills all of
space. That would be like scanning the ocean with sonar and saying the
only things that fill the oceans are the micro- and macro-organisms of
the ocean and nothing else. The sonar won't detect the medium on which
it is traveling, the water itself.

Such a motion could result from our "stationary"
position actually moving away from "The Great
Attractor". If all matter were generally moving
towards a single point, at a more-or-less constant

Either case, whether the objects in the Dark Flow are moving relative
to us, or we're moving relative to these objects, there is another
implication that must be acknowledged. One of the criterion used to
disprove the Aether theory is that we have not dected a preferred
direction of movement for objects in the Universe. Doesn't this "Dark
Flow" demonstrate a preferred direction of flow? Isn't this actually
the long sot after proof for Aether? Not the solid Aether of old, but
a liquid Aether?
