G = The galaxy's plane.
B
= The black hole in the galaxy's center, rotating around itself.
A = The arms created by absorbing the mass from the cone spinning at its side: The upper arm absorbs the mass arriving from the upper cone; The lower arm absorbs the mass arriving from the lower cone.


Recently it was discovered that at the center of every spiral galaxy there exists a supper-massive black hole.

This black hole rotates around itself at tremendous speed.

Also it was discovered that the black hole expels two hoses of mass from its two sides, in directions vertical to the galaxy's plane.

These mass-hoses reach distances of thousands of light years away from the black hole.

They acquire the rapid rotary momentum of the black hole.

 

My theory does explain the cause of the surounding movements of most of the planets in the univers. No other theory can do it !

     

 

   
   
In contrary to all accepted theories, my theory claims that the black hole creates the spiral galaxy.

*** The solution of the problem of the formation of spiral galaxies:

The supper-massive black hole in the center of the galaxy spins at tremendous velocity, forming a spinning pipe-shape.

From the two sides of that pipe-shaped black hole, two jets of matter escape at tremendous velocity.

The matter thrown out from the two edges of the black hole in directions vertical to the galaxy's plane at formidable force, has, in addition to the momentum of this movement, also a rotary momentum of extreme velocity, which is caused by the tremendous velocity of the spin of the black hole.

This momentum causes the mass to be thrown in the direction of the spin, thus creating a conical shape, which opens towards the outer limits of the galaxy's plane.

The spinning velocity of the edges of the cone is by far higher than that of the spiral's arms.
When the matter that is being cast away from the cone collides with the matter that has already been gathered at the edges of the appropriate arm, it adds its high velocity spin resulting from the cone's spin.
Thus it adds further propulsion to the arm, and this force gives it another push in its movement further away from center of the galaxy.

In other words: the arm curbs the new matter arriving from the center.

Note:

According to my theory, the velocity of stars situated on the plane of the galaxy (i.e., not on the spiral's arms), is lower around the center, compared with that of stars situated on the arms.

Explanation: The arms of the galaxy permanently acquire new rotary momentum from new matter that is being cast out from the black hole.

 


When examining spiral galaxies we discover that basically they are constructed of two arms,
which disseminate matter to great distances away from the center.

At the breakneck the super-massive black hole throws outwards two jets of matter,
at a very high velocity.
The amount of matter may be small, but, as a result of gravity, it adds up continuously,
to the matter that has already been thrown previously.
In fact, because it is smaller than the mass that has undergone this process previously,
it will be attracted to it until they merge, and the rotary momentum of the new material,
will be added to the matter that accumulated previously.

Thus, during millions or billions of years of accumulation of such matter that escapes
from margins of the black hole, the two spirals arms of the galaxy are formed.
Those spiral arms are permanently moving away from the black hole,
due to the enormous preliminary velocity of the original "throw".
One arm is formed on one side of the rotating black hole, the other -- on its opposite side.

Non of other theories can explain why most of the galaxies have symmetric shape.
I do explain this fact by the symmetric quantity and quality of the mass
thrown from both side of the black hole:
Both, quality and quantity, are changing from time to time,
and that is the clue for the shape of the arms.
But the mass thrown to both sides are identical, at a time.

Anyone wishing to contradict this theory,  is challenged to contradict the following predictions:

1 - The direction of the black hole's spin is the same as that of the opening of spiral's arms.

2 - All spiral galaxies starts with two arms, which emanate from the center and continue away from it.

3 - The arm facing us (i.e., the camera) is brighter, while the other arm is concealed
by the mass that has escaped previously and settled on the galaxy's plane.

4 - Stars situated on the galaxy's plane (and not on one of the arms),
revolve around the center of the galaxy at a slower speed in comparison with
stars situated on the galaxy's arms.

5 - The jets of new mass are at first vertical to the galaxy's plane,
but with the passage of time they tend to change direction towards the dense side of the galaxy's plane,
in the direction of the emitting arm.

6 - In young galaxies, the stars' movement direction is more outwards than inwards, from to the center of the galaxy.

7 - The closer the spiral's arms are to the black hole's center, the more convoluted they are.

One other point:
The way the two arms split, can be caused only by explosions.
Notice that the angles of those splits are towards out from the center !!!
That caused by continuing the previous movement out...

 

Photographs :

The following photographs provide confirmation that assist this theory:
i.e., that one of the galaxy's arms is situated above galaxy's plane, while the opposite arm is situated below it.

For those readers who may unaware of it, the pictures in most of the links brought here,

By the way, the above mentioned "bar" is vertical to the galaxy's plane.
Notice that the photograph was taken from an angle that enables to see it partly
from the side and partly from above.

It is interesting that the arm situated above, towards the camera, is seen clearly,
whereas the second arm can not be seen in the picture, apparently since it is situated below,
i.e., under the plane of the galaxy.

Subject: Another spiral galaxy. Here we can see a somewhat different phenomenon,
the whole left side is bright and dense with mass, compared with the right side,
which is clearly sparse in matter.

Subject: A ring-shaped galaxy.
Wild conjecture: old spiral galaxy. Maybe this was a spiral galaxy, which ceased
to generate new matter, and the "old" matter moved to far distances away from the center.
Just a conjecture!

Subject: Another almost annular galaxy. Notice that small amount of mass is
still thrown out from the center.

 Only a fine trail from the center to the ring can be discerned,
plus another small trail (from below?).

My assumption is that over time this galaxy will turn into an annular galaxy,
like the one that I showed above.

Subject: Another annular galaxy. Also here the arm directed towards the camera,

Another arm, probably pointing down, looks pale and partial.

It indicates a high probability of the existence of a common source for their creation. 
 Http: / / www2.yarden.ac.il / bloss / apod / ap010510.htm

Subject: A thrilling picture!! A cluster of galaxies with brightly shining center.

The fact is that the planes of the many spiral galaxies seen in the picture are tangential
to the circles around the shining center.

Also interesting is the fact that "stripes" can be seen clearly.
These may be an evidence of material that was dispersed radial.
I assume that over time those "stripes" will serve as a nucleus for the formation of a galaxy.

Subject: Another spiral galaxy. Pay attention to the explanation:

The arms open in the direction of the rotation.
Is this not a proof of the fact that the mass is thrown from the center outwards
(but not the other way round) ?

By the way, a note concerning the previous picture of x-rays.
A column of radiation 30,000 light years long, vertical to the plane of the galaxy,
is supposed to appear also on other side of the galaxy, but it is concealed by the galaxy.
It is part of the mass  thrown from the black hole.

The heavy mass dissipates alongside the galaxy, in the cone, but the X rays
continue at a straight line, in the direction of the jets.

Subject: Another cluster of spiral galaxies. Prominent here are parts of arcs,
a similar picture was shown above.
In both pictures the lines of the arc are delicate and partial,
and discerning them requires some effort.

My conjecture is that they constitute a portion of matter that is thrown out from center of the cluster,
probably in a way similar to the formation of rings around the center of a galaxy.

Subject: An unusual spiral galaxy. A split in the inside of the arms:
It can be seen clearly that the two original arms of the spiral split a few times into secondary arms.

Subject: Another spiral galaxy. Two typical arms. Relatively low quality of picture.
Http: / / antwrp.gsfc.nasa.gov / apod / ap990926.html

Subject: Another spiral. Here there is a special phenomenon:
in the galaxy's center two arms-like "protuberances" emanate from the center.

It is hard to discern from the photograph if those arms emanate vertically,
relative to the galaxy's plane. If so, it is a rare photograph showing a very big amount of mass,
most likely originated from the black hole, towards the two arms.

Http: / / antwrp.gsfc.nasa.gov / apod / ap990815.html

Subject: Another spiral. Prominent here is the splitting of the two arms into secondary arms.

It looks as if this process of splitting is repeated in the arms,
and finally causes the creation of a homogenous plane around the center of the spiral galaxies.

Http: / / antwrp.gsfc.nasa.gov / apod / ap990609.html

Subject: Another spiral. Also here are two typical arms.
Also here "protuberances" of radiation from the center of the galaxy can be seen clearly.

Photograph from 1999 (the explanation should not be taken too seriously).
Http: / / antwrp.gsfc.nasa.gov / apod / ap990510.html

Subject: Another galaxy with radiation on both sides of the center.

By the way, a note concerning the previous picture: notice that the radiation angle,
of the halos on both sides of the center are not vertical at 900 relative to the spiral's plane,
but are slightly tilted sidewise, a fact that supports my theory.

The tilt on both edges is in directed towards the "thicker" part in the spiral.
This is a result of the dissipation of matter from the center in that "thick" direction.

Http: / / antwrp.gsfc.nasa.gov / apod / ap981220.html

Subject: Two spirals that reach towards a contact between them.
Please notice the directions of rotation of both spirals. They rotate in contrary directions.

My conjecture is that most (if not all) colliding spiral galaxies rotate in contrary direction,
which shows that they do not originate from a common source.

Http: / / www2.yarden.ac.il / bloss / apod / default.asp? Date=9 / 25 / 2003

Subject: Another spiral. Notice especially the center of the spiral:

The two brightly shining arms can be seen clearly as they emanate --
The left one towards the camera, continuing to protrude, while the arm at the right,
gradually disappearing under the galaxy's plane, and its continuation can not be seen.

Http: / / antwrp.gsfc.nasa.gov / apod / ap990624.html

Subject: Another spiral.  Here the center of the spiral is thrilling.
Two arms emanating vertically from the spiral's center deviate a little
from the vertical and disperse the mass to the direction of the galaxy's plane.

An asymmetric swellings on the galaxy's plane can be seen clearly.
Each "arm" creates its own swelling.
A very similar photograph was presented earlier in this cluster.

Subject: Another spiral. Also here the center shines brightly, with two arms.

One can see that the arms directed downward towards the camera,
continues directly to the arm, whereas the other arm disappears into the galaxy's plane.

Notice the galaxy behind. It is less clear due to the distance,
but what is most interesting  is that also here you can see two horns emanating
at the same angle as those in the nearer galaxy.

My conjecture is that it indicates a rotation axis identical in direction in both galaxies.
This may be an indication of a common source.

Subject: Another beautiful spiral. Mass spread out in the whole plane

By the way, I assume that the splitting of the spiral's arms into secondary arms
is created as a result in the end of the arm.
The explosion create a shock wave which splits the arm, but the original momentum
of the material causes it to continue both in the direction of the original movement
and in the direction of the split. It seems that the blast force is much smaller than the arm's inertia
and therefore the deviation from the trajectory is not more than the original.

Subject: Exceptional picture. The galaxy is photographed from the side,
with two immense domes emanating from the two edges of the center.

What can be learned from this picture is that the new mass,  that thrown from both edges
of the black hole,  dispersed to the sides and they form two very wide cones.
Due to gravitation power,  this mass pulled and attracted towards the  galaxy's plane.

I surmise that the rotation speed of the immense domes is very high relative to that of the galaxy.

old picture, shows an outstanding arm at the right,
and non-clear arm at the left, because is covered by the substance of the galaxy.

Another shining center in a spiral galaxy.
Please notice the single arm seen here, at the right.
The other arm is hidden by the galaxy plane.

"Scientists say most galaxies, including our Milky Way galaxy, have a suppressive black hole at their core.
A suppressive black hole contains the mass of millions to billions of Suns compressed within a region smaller than our solar system. The black hole in MCG-6-30-15, over 100 million light-years from Earth, has the mass of about 100 million Suns.

"This mass implies an innermost stable orbit of 64 kilometers (40 miles) if the black hole were not spinning, according to the study. But a spin rate of 450 times per second implies that incoming blobs could cozy up to within 49 km (about 30 miles). "

"A suppressive black hole at the center of this galaxy, Centaurus A, blasts two jets of high-energy particles into space. Astronomers use the outflows to help them understand the shape and physics of black holes"

Chandra determined that there are two vast, bubble-shaped cavities in the gas cluster that extend away from the central black hole. The new observations, performed by Andrew Fabian of the Institute of Astronomy in Cambridge, England and his colleagues, reveal the presence of ripples, spaced 30,000 light-years apart, that emanated from the cavities."

"Chandra observations of a third stellar black hole, GX 339-4, have revealed that it is also spinning rapidly, and clouds of warm absorbing gas appear to be flowing away from the black hole at speeds of about three hundred thousand miles per hour. Such warm gas flows have been observed in the vicinity of suppressive black holes"

"The amount of energy in the black hole, provided by a constant stream of gas clouds and sucked-up stars, is staggering. Indeed, co-author Mitchell Begelman of the University of Colorado reports that "it would take roughly a billion years to release all the energy stored up in MCG?6-30-15"

"There is no intrinsic mass limit on a black hole. It could be very light or very heavy. We call those much heavier than one solar mass suppressive black holes. We find several at the centers of some galaxies. For example, the core of M87 contains 3x109 solar masses within a few light weeks. Only a black hole allows the presence of so much mass in such a small region."
