The Universe is, or the local Universe we exist in is in, a jet;
analogous to the polar jet of a black hole.
The analogy is a bunch of objects floating downstream and exiting the
mouth of a river. As the objects exit the river they move away from
one another. This is analogous to dark energy. Even as the objects are
exiting the mouth of the river and moving away from one another the
water still pushes back and exerts pressure toward the objects. This
is analogous to gravity.
Aether has mass. Aether physically occupies three dimensional space.
Aether is physically displaced by matter.
Displaced aether pushing back and exerting inward pressure toward
matter is gravity.
This is what Voyager found evidence of.

"Voyager is showing that what is outside is pushing back. ... Like
cars piling up at a clogged freeway off-ramp, the increased intensity
of the magnetic field shows that inward pressure from interstellar
space is compacting it."
The aether is, or behaves similar to, a superfluid with properties of
a solid.

"The universe was born spinning and continues to do so around a
preferred axis"
The Universe spins around a preferred axis because the Universe is, or
the local Universe we exist in is in, a jet; analogous to the polar
jet of a black hole.
'Mysterious Cosmic 'Dark Flow' Tracked Deeper into Universe'
http://www.nasa.gov/centers/goddard/news/releases/2010/10-023.html
'The clusters appear to be moving along a line extending from our
solar system toward Centaurus/Hydra, but the direction of this motion
is less certain. Evidence indicates that the clusters are headed
outward along this path, away from Earth, but the team cannot yet rule
out the opposite flow. "We detect motion along this axis, but right
now our data cannot state as strongly as we'd like whether the
clusters are coming or going," Kashlinsky said.'
The clusters are headed along this path because the Universe is, or
the local Universe we exist in is in, a jet.
The following is an image analogous of the Universal jet.

The reason for the 'expansion' of the universe is the continual
emission of aether into the Universal jet. Three dimensional space
associated with the Universe itself is not expanding. What we see in
our telescopes is the matter associated with the Universe moving
outward and away from the Universal jet emission point. In the image
above, '1st Stars' is where the increase in pressure caused by the
aether continually being emitted into the Universal jet causes the
aether to condense into matter.

Universe, we exist in.

Dark flow is the aether emitted into the Universal jet. Dark energy is
the change in state of the aether emitted into the Universal jet.
