Default Dark energy

I would like to propose that dark energy is not a repelling force but a
propelling force.

To prove this theory I need to explain the accelerated expansion of the
Universe not being a result of a dark energy that arises as a repelling
force, but it has a different explanation.

Secondly I would show why dark energy is a propelling force.

One begins with the freefall of stars in a spiral galaxy. Due to
gravity the falling stars condense over time. Since gravity is loose in
a spiral galaxy, stars organize on spiral arms and not fill up the
galaxy's disk proportionally. If the stars would be tied to a galactic
center gravitationally, then the stars would fill up the galactic disk
and not only move about loosely in spiral arms. But over time as there
is gfravity these spiral arms tighten and stars will fill the galactic
disk more and more densely on a disk and less like spiral arms as the
spiral galaxy condenses from grvitation. In other words a spiral galaxy
not only rotates, but its spiral arms are condensing, to an eventual
condition where the Suns fill up the disk of the galaxy and are less
gravitationally traveling in great distances out from the galaxy's core
in long spiral arms. The effect is that as a spiral galaxy is
condensing, the spiral arms fold closer toward the galaxy's core.
Remember, the whole spiral galaxy is condensing as it rotates over time
as all freefalling objects experience gravity which in the long term
compresses.

If one uses his imagination he would see that the compression makes the
spiral galaxy rotate faster and faster, but one might use his
imagination further and suggest that a galaxy that compresses its
energy not only gains a faster rotation but the galaxy that has a
momentum would also gain speed. Its like a figure skater pulling arms
in and speeding up with the spinning, but if there is a slight sideways
movement, then that movement would also gain speed with the faster
rotation. Then if galaxies do gain speed due to compacting spiral
galaxies, then like trains on tracks speed up in all directions, the
Universe appears inflating, expanding at an accelerating rate.

Dark energy as propelling force, and not a repelling force:

How science explains dark energy as a force related to expansion of the
Universe:
http://hubblesite.org/newscenter/arc...eases/2004/12/

Current science speculates that dark energy behaves opposite to
gravity, a force that repells galaxies apart.

Following through the logic: Suns are freefalling gravitationally in a
spiral galaxy. In spiral galaxies the central mass is not strong enough
to hold the galaxy together, instead chaotic, local gravitational
forces in spiral arms gravitationally tie the galaxy. As Suns fall
freely, each on its own, on average the spiral galaxy slowly tightens
as it rotates. The effect is that a spiral galaxy orbits faster and
faster over time due to compression. Eventually a spiral galaxy
tightens into a structure, where the spiral arms are lost, and a
central gravitational force takes over, in such a galaxy where stars
would fill up the galaxy's disk.

Since local gravitational forces dominate a spiral galaxy's disk and
not a central gravitational object is responsible for holding the
galaxy together, stars organize in spiral arms. As the spiral galaxy
compacts, it gains rotational speed, which increases the galaxy's speed
of heading in the Universe as well according to this theory. The result
is that all spiral galaxies that have momentum in space are gaining
speed toward their heading. All spiral galaxies may be viewed as trains
that are slowly accelerating their speeds on their tracks, and the
result is that with all galaxies graining speed in all direction the
Universe appears inflating, expanding in all directions at an
accelerated rate.

It is not dark energy that is responsible for this effect, but the ice
skater in the ring pulling in the arms and gaining 'combustion'. :-)
There may not be a repelling force between galaxies.

But dark energy exists. There is speculation that once taking a galaxy
and rotating it, the galaxy would tighten, because we only see 10
percent or so of the overall mass, and because elliptic galaxies were
shown to have little or no dark matter energies. So the dark matter
energy phenomena would be attributed to rotating galaxies according to
findings.

Dark energy is complex as it is most likely stirred up from the
galaxy's rotation. In a NASA announcement dark energy stayed around,
the shadows of dark energy moved on almost uneffected after the chaotic
collision of two galaxies. A whirling energy in space that moved on. A
whirling that somehow seems to have built up from a galaxy's propelling
motion through space.

The galaxy has a disk that rotates, and objects moving on this disk
move faster. The disk carries gravitational properties, but not
properties that repell, but one that propells, and this propelled
gravitational field on the disk of a galaxy bends light. Gravity merely
sets objects into motion. This field (galaxy disk) does just that, the
whole disk is gravitationally rotating (inerts the paths of objects
toward the galaxy's disk), and that's why light curves in the vicinity
of a stirred up gravitational energy of a rotating galactic disk
gravitationally: because gravity sets matter into motion, and the
motion in a heavy and accelerating rotating galactic mass effects the
gravity of objects in the vicinity of this galactic-scale rotation.

Its the balance of nature. Objects organize to fall toward each other
on a gravitational plane, on a disk, and there is a galactic
gravitational plane that aligned the stars to be on the same disk.

It is a large balance, where millions of Suns are aligned and orbit
toward the same direction in a galaxy. Like a sea of moving stars, each
star falling freely, one after another and create a flow of stars, a
flow that is also connected to the complex flows of a spiral galactic
system.

As all the objects in a spiral galaxy freefalling on a galactic disk,
their average distances over time shrink due to gravity being involved,
gravity tightens a galaxy, and the objects are freefalling at faster
and faster rates on the disk as the galaxy compacts. The speed of our
Sun in our galaxy is 220 km/second.

As all the stars in a galaxy rotate and the stars tighten, an alignment
force to the galaxy's disk strengthens. Along this disk stars move
faster. The stronger the alignment force to a galaxy's disk, the faster
objects on the disk rotate. And this disk also 'builds' freefalling
energy toward the orbit of the galaxy. And as gravity sets matter into
motion, this field is gravitational. One might use the term:
freefalling energy.

There is evidence that dark matter is gravitational energy that is

a) stirred up as freefalling energy (see Nasa announcement that dark
energy remained after two galaxies collided and tangled up, but two
dark energy shadows continued propagating in space [according to this
theory 'rotationally'])

b) found in high quantities in the vicinity of spiral (rotating)
galaxies.

--

A general assumtion may be that since a compaction in a galaxy, a
decompaction force arises (see link to article above), perhaps a dark
energy that repells Galaxies apart, one counter force of compaction,
one that Einstein speculated on: that as long as spiral galaxies are
compacting over time, an anti-gravitational dark energy field would be
produced somehow, and according to current theories dark energy may act
as a repelling gravity causing the expansion of the Universe.

I don't think that dark energy is a repelling force, but strictly a
propelling force related to the rotation of a galaxy. I think that the
expansion of the Universe is not due to a repelling force that arises
from compacting spiral galaxies. I think that the propelling forces of
freefall energies corresponding to a heavy rotating galaxy is what is
measured as dark energy.

One would not find dark energy in elliptic galaxies, only if the
elliptic galaxy contains a 'growing' disk embedded deep inside the
elliptic galaxy's core which is usually covered from view by the stars.
Scientists (don't remember the source, at a University in the USA, a
study announced at the Astronomy department of the University of Ohio I
think) did indicate that little or no traces of dark energy were found
in their study elliptic galaxies.

Summary:

1. Dark energy may not be a repelling force but a propelling force of
gravity. Introduced 'freefall energy'.

2. The alternative explanation to why the Universe is expanding would
be a result of galaxies speeding up like trains in all directions due
to compacting spiral galaxies that gained momentum.

It is also important to see that this theory upon analysis may
invalidate the general theory that there is a repelling dark matter
energy force causing the expansion of the Universe, but rather
combustion related to gravitational compression drives spiral galaxies
to gain speed. Dark energy arises from an accelerated freefall energy
(and carries gravitational properties).

[Rest deleted for brevity]

Observationally, there is no support for your speculation about galaxies
condensing. Radial velocity curves are practically flat for spirals,
including our own. The arms are a bit of an illusion in that they are
highlighted by bright massive stars with short lifetimes relative to say
low mass stars like the Sun. Stars are found between the spiral arms,
but tend to be the lower luminosity, longer lived stars.
