How about using real terms instead of this gobbledegook, Jeff? lmao!
Look up Kepler>s Third Law for help.

The frizbee is not Keplerian because, for each degree turn,
both the Velocity and the Distance are higher at the edge;
i.e. the action is much higher at the edge, not constant throughout.
If I>m not mistaken, the Milky Way is part Keplerian, part frizbee;

Cactus saul We could also relate our faster or slower speed as well.
Say the star is coming to us at 60 mps,and we are moving away from it at
60mps What then? Best to keep in mind Saul The effects of SR depends
upon how fast one moves. I know Cactus Saul you are bringing in Lorentz
contraction in which a moving object is shortened in its direction of
motion(Yes) We must not forget the part gravity plays in this
scenario. Nor its ability to curving the path of light making its travel
time longer. Going with QM and string theory thinking Light is a wave
vibration,and its wave length gets shorter or longer with
acceleration,and gravity. Also Saul if it curves that has the same
effect on it as acceleration. I find curve as a part of spin,and
it helps my Spin is in theory Go figure Bert |

ever said about the M.W. being invisible. The statement was made that
unlike the solar system which has 99% of its mass concentrated in the
center, in the Sun, a spiral galaxy has a much higher percentage of
its mass spread out peripherally. Mutual gravitation in the outlying
mass would contribute substantially (if not in toto) to the galaxy>s
non-Kelperian rotation.. thus ameliorating the perceived need for
"dark matter". |

Blame it on dark matter, Paine! lmao!
A "solid disk" rotation is impossible either way whatever the reason
is.

These are called Doppler shifts, Jeff.
Some stars are moving away (redshift) and some are coming towards us
(blueshifts).
Since galaxies don>t rotate as a solid disk (BEERTbrain has claimed
otherwise!) they do show faster shifts close to the nucleus and slower
shifts farther and farther out.
Actually, Saul, according to what i>ve read, Bert is more
right than wrong on this. E.g....
http://en.wikipedia.org/wiki/Galaxy_rotation_curve
While velocity studies seem to suggest that the rotation
curve is not perfectly flat, that spiral galaxies don>t go
around in precisely the same manner as a solid disk or
a frisbee, the rotation is a lot more like a solid disk than
Johannes Kepler would have guessed.
It>s certainly not as Keplerian dynamics would predict.[/quote] |

Ody When you compare my far out thinking to the great imperial thinkers
and I end up more that 50% right I am greatly flattered. I think I am
closer to 75% on the money Go figure Bert |

You joked:

You saw 5 percent of it, which hardly counts.
If you saw 5 percent of me, my left foot, would that mean you saw me ?
β The dark matter halo is the single largest part of the [ Milky Way ]
as it covers the space between
100,000 light-years to 300,000 light-years from the galactic center.
It is also the most mysterious part of the Galaxy.
It is now believed that about 95% of the Galaxy
is composed of dark matter, a type of matter that
does not seem to interact with the rest of the Galaxy>s
matter and energy in anyway except through gravity.
The dark matter halo is the location of
nearly all of the Galaxy>s dark matter,
which is more than ten times as much mass as all of
the visible stars, gas, and dust in the rest of the Galaxy.
The luminous matter makes up approximately .09 tera solar masses.
The dark matter halo is likely to include around
[ .6 tera to 3 tera ] solar masses of dark matter. β

Do you know what β action β means in physics ?
β The Planck constant has dimensions of energy multiplied by time,
which are also the dimensions of action. β
β The dimensions may also be written as momentum times distance
(NΒ·mΒ·s), which are also the dimensions of angular momentum. β
-- WikiPedia [ Action = Mass * Velocity * Distance ]
The action, per degree turn, is highest at the edge of a frizbee.
Action Per Degree is constant for an object in Keplerian motion.
At the apogee, the speed is slowest
and the distance traveled ( per degree ) is highest.
If the speed of the stars orbiting the Milky Way
is the same no matter the distance from the center,
the the action per degree is higher at the edges ..
but not as high as it would be if it were like a spinning frizbee. |

Our scout leaders called it Mulligan stew, Jeff. It tasted quite
good.
We were "camped out" in a cabin in North Park in the Pittsburgh area.
I doubt the homeless get to live there.
That cabin used a pot-bellied stove. One night I had to stay up late
to feed wood into the stove to keep it lit.

Read Kepler>s Third Law, Jeff.
It says the same thing, but much more succinctly.
