Thank you to everyone for taking the time to contribute,
Your most recent posts have offered a great challenge.
Again, I will respond to them in the order they appear in the thread.
But first, a couple of points.
How long does the precession of the stars take?
Hipparchus calculated the precession at around 1 degree in a little over 75 years.
Ptolemy mistakenly thought Hipparchus claimed 1 degree per hundred and used that figure. Theon of Alexandria accepted Ptolemy's number and that stuck
for a few hundred years.
Albategni (d. 929 A.D.) calculated 1 degree in 66 years
Al-Biruni (d. 1048 A.D.) calculated 1 degree in 68 years
It is quite possible and almost certain that the orbit around the Hammar Axis is not circular and would therefore not appear to have a consistent
speed viewed from Earth. The above mentioned people were brilliant in their time and apart from Ptolemy may not have been in error at all.
Not all stars conform to the precession of the stars. The idea of the precession came about long before telescopes and concerned stars viewed
with the naked eye.
The star “
Deneb” is said to be the 20th brightest star in
the sky. It is one of the most remote stars visible to the eye at an estimated 1,425 light-years away from Earth, well within range of our Hammar
Axis.
There are many with arbitrary proper motion vectors and scale factors including “runaway stars” and “hypervelocity stars”. For more
information on stellar kinematics of particular stars you can use one of the “proper motion” catalogues e.g.
USNO Flagstaff Station.
This is one of the interesting phenomena that lead me to question a wobbling axial tilt.
The orbital plane of the Moon stays constant to the ecliptic. The position on the horizon of the full Moon rise in any given season would not
be as constant as we know it has been over thousands of years if it changed. We’re not talking dates here, eclipses and what not, but how far North
or South on the horizon the Full Moon rises in a given season.
Please study the following for a better understanding than I can give you:

The Moon’s constant orbital plane was one of the last things I discovered that supported the idea of the Hammar Axis. It is the giveaway that the
Earth’s axial tilt does not wobble.
Please, study it, understand it.
Ok, time to offer my replies:

A galaxy would not undergo precession in your model, instead all the stars would appear to precess while galaxies do not, resulting in a very high
apparent motion of every other galaxy with respect to the stars (50.3 arcseconds per year). This is not what is observed though when we look at the
stars and galaxies.
Yes, the galaxy would not undergo precession, they’d appear to have different stellar kinematics than the stars orbiting
the Hammar Axis as stated above.

As an example, here's a comparison between one of my first deep space astrophotography pictures I took about 6 years ago and a sky survey image from
about two decades ago. This is the galaxy NGC 891. Later I can also compare it to a more recent image I have of the same galaxy, it tells the same
story. Notice how the galaxy is still in the same place relative to the stars. They should be different by at least 10 arcminutes if your theory is
correct. In other words, the galaxy should be displaced relative to the stars by over 2/3rds the width of the image itself.

Well done with your photo’s by the way it must have been a thrill to see
that for yourself with your own eyes. I’d love to try that some day.
Remember, with the popular and accepted rate of precession at 1 degree per 72 years, even changes in distant objects would take more than ten or so
years to become greatly noticeable.
Let’s have another look at the animation, this time slowed down a bit:
* The full cycle represents the approximate 25,920 year precession period. Each animated step is roughly around 2,160 years.
* The Orange coloured circle represents our solar system and the blue arrow points to the direction of midnight on December 22 in all 25,920 years in
the cycle.
* The months around the outside just represent the direction of midnight in those months, again, in all 25,920 years. (If the months are confusing,
just ignore them.)
* The coloured dots (the single ones closer to the centre and the triplets around the outside) represent star constellations that orbit around the
Hammar Axis. These stars are all within the Orion Spur.
* The Galaxy, or any thing that’s outside the larger spinning circle can be used to represent far off objects that are not part of the precession of
the stars. Viewed from the Earth at midnight December 22, they have a different movement than those sharing the orbit around the Hammar Axis.

SC: If our galaxy and other galaxies were part of a 'super-spur' of a 'super-galaxy' that also rotated in the manner of the Hammer Axis theory
then might not this explain 'locally' observed precession whilst the motion of the super-galactic spur would maintain the relative motion of other
galaxies with respect to our own? Kind of like a fractal - galaxies within super-galaxies, within even more super-galaxies.
Sorry Scott, as
good as that sounds, I don’t quite follow that. Are you suggesting clusters of galaxies are moving in sync in yet another, even larger, spiral?

I think the 13,000 year events could be caused by the close interactions of the arms as we cross the Galactic center. See the attached crude image of
what I mean.
edit on 17-1-2011 by n55rc because: mis spelled
Wow,
wow, wow, Yes! Absolutely! This may also support concerns about the approach of the galactic plain. It could be easy to imagine the gravitational
effects of other galactic arms to be greater at each “Interaction Zone”.
Thank you for linking to that Image.

NGC 891 is roughly 27.3 million light years from earth.
en.wikipedia.org...
Let's find out what the 50.3 arcseconds/year rate of precession equates to at the distance of that galaxy. Arc length distance equals the radius of
the sphere times the separation in radians. 50.3 arcseconds = 0.000243861282 radians. The radius in this case is 27,300,000 light years. That means
the galaxy must be moving at a speed of 6,657.413 light years per year (that's 18.2 light years per day or more than three quarters of a light year
per hour). Even the starship enterprise couldn't keep up with that. This is, of course, a relatively close galaxy though it's not a part of the
Local Group of galaxies. More distant galaxies only become more absurd.
Actually, distant objects would actually appear to be moving much
slower. Take another look at the 2D animation.
I still can’t get over you seeing NGC 891 with your own eyes, awesome!

I'm sorry, but I disagree with some of your theory. Being part of a binary system is a good theory, not yet proven. However, in 1982 NASA came out
with a report defining a 12th celestial body that comes in and out of our system every X amount of years. This can be looked up on through headlines
of the time. Its very possible, that this could be a brown or red dwarf, which would explain why this object it so hard to spot.
Ok, but I
don’t have a binary star theory, that has been offered by others and I have only stated that I don’t disagree. On that all I can say is “I
don’t know, perhaps and perhaps not”.

I believe the earth's wobble has been proven time and time again and is a valid theory. You also didn't mention the precession on the earth itself
in the right context ( although the article is good ) . In which the Earth shifts 1 degree every 72 years following a 25,920 cycle, which in turn is
divided into 12 solar cycles of 2160 each. ( give or take, each cycle is not exact, some are longer that the other ). marking climate change on each
cycle, changes in position of the Earth relative to the stars and the sun.
I understand the strength of widely popular ideas,
Giordano Bruno was killed for them. I’m so glad I live in a different time. The Earth’s
wobble is just an illusion viewed only from our planet. You’re right, I didn’t go into the precession in great detail, that is not my intent but
instead to demonstrate a model that shows how the tilt of the Earth’s axis stays as true as the line drawn by a swinging
Foucault Pendulum bob.

We also run in to the Galactic equinox/equator once every 35,000,000 years. Which in turn can cause gravitational pulls on the earth, the other
planets, and the sun. We actually bounce up and down slightly along this galactic equator though out this time period.
I’m not sure about
your figures there and the effects sound highly speculative. “Bouncing up and down”? Perhaps in regard to a 2D side view representation of our
spiral path, then yes.

Stonehenge's alignment with the moon only comes into play with the moon every 19 years. The moon's orbit is in a 19 year cycle around the planet (
book = When time began [ other sources within same book very well noted that can be researched } ) .
Yes, when using dates for eclipses etc.
the 18-19 year cycle is important. Monuments such as Stonehenge also track the Northerly and Southerly path and extreme North and South positions of
the Full Moon rise on the horizon too.

Also, where are you going with all this ?
I just want to share my idea that the tilt of the Earth’s axis doesn’t wobble as previously
believed and I believe it is the model of the rotating galactic arms which demonstrates that.
We rejoiced when we circled the Sun, now we can again as the Earth becomes more “solid ground”.

Gravitational calculations for any[/] two masses generally considers them as as point sources, to simplify the equations, and to a close
approximation. There is a reason that most orbits fall generally equatorially until the orbital body is at a fair distance from the parent body, when
the effects are less pronounced, and orbits tend to get wilder. That's why the solar system bodies fall in a rough plane around the sun
(equatorially) until we get to the erratic orbit of Pluto, and farther out the more nearly globular effects of the orbits in the Oort cloud. Likewise,
the orbits of the moons of the larger planets, Jupiter and Saturn, fall equatorially until we get to the outer moons,which again orbit more
eratically.
The concrete slab analogy was nice, but doesn't take into account that the gravity of a far larger body (in that case the Earth) dominates the
interactions of all the lesser bodies (concrete slab, water, and beach ball) far more strongly than their own gravities interact with each other. In
that way, it's a flawed analogy. Also, it doesn't take into account that the concrete slab (representing the ecliptic) represents not a solid
construct, but rather a construct entirely dependent on something else (in this case the Earth's orbit) for it's very existence. The ecliptic is NOT
a "concrete slab", and has no mass of it's own at all. Mass is everything when calculating gravitational interactions.
nenothtu, I think
you have demonstrated an understanding of all the points here, thank you for joining in and helping to clear up some of the misunderstanding.

Your diagram is incorrect. You're putting the level of the moon's orbit parallel to the slab. It should be parallel to the water level in the
pool.
Yes, I’m sorry, I made the image from memory of what you wrote and I got a few things around the wrong way. It wasn’t till I was
posting and re-read what you wrote again that I realised. The principal is the same never the less. I’ll make another image to match your
description exactly when I get the time, hopefully tomorrow. I’ve hand drawn it, just not done it on computer yet.
Originally posted by nataylor
When you do that, you'll see that both northern hemisphere winter solstices are identical and both northern hemisphere summer solstices are
identical, meaning the precession had no effect on the relative position of the moon and the sun to each other.
Nothing to do with solstices
or eclipses, but the
position of the rising
Full Moon around the same time of year. Unfortunately the Moon doesn’t orbit Earth in a
nice and neat fashion so eclipses occur at different times each year. However, it does orbit in a fashion that the
Full Moon rises in the same
place on the horizon each season, just like the Sun does.

Good luck on future projects!
Giving up so soon Polestar? I’ll quote myself back to you:

It is more likely that I have failed to explain myself clearly if you see a contradiction in my idea. I’m open to have errors pointed out once
I’ve removed all confusion from my explanation. Right now, I’m still trying to put the idea into the right words so it is clear to
everyone.
I fail to see my own contradiction that you said was there. I would appreciate you helping me see it if you are still sure it is
there.
Once again, it has been a real pleasure to discuss this idea with you. Your posts have been incredibly thought provoking.
Many kind regards until next time.
