Timekeeping and retrogrades
The observed stationary points between observed motions of the inner and outer planets have two distinct causes -

It is crucial to understand this observation insofar as the foundations of timekeeping rely on the observation that as Sirius shows up for the first time as a morning appearance, it skips an appearance by one day after four cycles of 365 days/rotations. Putting the motion of the inner planets as they move from an twilight to a dawn appearance or from the left side to the right side of the Sun makes the line-of-sight appearance of the background stars as they disappear and reappear in sequence as proof of the Earth's orbital motion - https://www.youtube.com/watch?v=eeQwYrfmvoQ Building astronomical insights from scratch using imaging is even more exciting than building the first computers in garages and leaving behind those who simply can't keep up. |

I've shown you before, with tables of data, that the inner planets are not at or near greatest elongation when they reach a stationary point: https://en.wikipedia.org/wiki/Aspects_of_Venus |

Here's a diagram from the viewpoint of the sun from one of your favourite sites. No retrogrades. Just as the satellites of Jupiter are furthest from the planet before they turn back towards the front of the planet and as they move from left to right so also Venus and Mercury reach their widest point from the Sun before turning back in from left to right and in front of the central Sun - https://www.youtube.com/watch?v=kjfQCTat-8s http://www.popastro.com/images/plane...ary%202012.jpg The background stars also move from left to right due to the orbital motion of the Earth but this time behind the Sun and its glare and show up as a morning appearance a few months after disappearing from view.The perspective of the inner planets therefore transfers to the background stars in an indirect way but this perspective is crucial for understanding the principles of timekeeping. I know only too well that you would rather die than adapt to the joys of 21st century imaging or that you can believe that there are more rotations of the Earth each year than dawn and sunsets but I wouldn't consider myself a man or human if I had to live for a single day like that. |

Anyone who encounters the empirical principles would know that they go too far so instead of doing an audit 100 years ago they made things so much worse by asserting that Newton was only right at large scale observations.
Stripped of its pretense, observers have the complete story of a train wreck and how it came to be that way with mathematicians chancing their arm with astronomy, it methods and its insights. In an idea world the awful attempt to make an hypothesis at an experimental level stretch all the way to an astronomical or terrestrial science scale would be seen as entirely counter-productive and while analogies have their place they cannot stand as representative of the dynamics of a planet and what moves objects around a parent object. Rule III. The qualities of bodies, which admit neither [intensification] nor remission of degrees, and which are found to belong to all bodies within the reach of our experiments, are to be esteemed the universal qualities of all bodies whatsoever. http://www.thenagain.info/Classes/Sources/Newton.html It is the easiest thing in the world to point out that following a meaningless attempt to force astronomy into experimental sciences is a horrendous waste of human resources as this is a nuclear bomb going off in science. The other option is re-introducing and modifying insights which constitute the switch from geocentric astronomy to that of planetary dynamics and then looking at the use of analogies once more and especially those relating to electromagnetism. |

The celestial sphere observers are resolute in their own peculiar way and the experimental theorists are off in a world of their own so it would leave on a tiny minority willing or able to go through the historical accidents which prevent the use of contemporary tools to be astronomical creative or productive.
While the theorists and the goto observers sing off the same sheet they don't have any real interest in astronomy, at least beyond a Universe bounded by their local horizon contained in a rotating field of stars. It means that they are highly unlikely to be able to deal with all the challenges which astronomy represents and especially at the juncture where geocentricity meets heliocentricity and compounded further by the mutations Newton introduced. One of the more significant advances of the past year has been getting rid of the last vestiges of the geocentric framework retained by the original heliocentric astronomers by accounting for both the motions of Venus/ Mercury and that of the Earth by using a two stage process. The shift to the line-of-sight annual motion of the stars behind the Sun due to the orbital motion of the Earth should shake observers out of judging the daily motion of the stars from horizon to horizon and around Polaris - https://www.youtube.com/watch?v=eeQwYrfmvoQ The late 17th century people tried to create a ideology that the Sun around the Sun was just as valid as the Earth around the Sun using the Sun's motion through the Zodiac, something which they borrowed from the original geocentric astronomers but this time they threw in the 24 hour system and the calendar framework to make that call - "Here take notice, that the Sun or the Earth passes the 12 Signs, or makes an entire revolution in the Ecliptic in 365 days, 5 hours 49 min. or there about, and that those days, reckon'd from noon to noon, are of different lenghts ; as is known to all that are vers'd in Astronomy." Huygens This is a lead in to the Equation of Time which is a timekeeping facility which evens out the variations in the length of the noon cycle to a 2 hour average and constitutes not only Newton's absolute/relative time but also his mutation of Kepler's insight into orbital distances in respect to orbital periods - "Absolute time, in astronomy, is distinguished from relative, by the equation of time. For the natural days are truly unequal, though they are commonly considered as equal and used for a measure of time; astronomers correct this inequality for their more accurate deducing of the celestial motions...The necessity of which equation, for determining the times of a phænomenon, is evinced as well from the experiments of the pendulum clock, as by eclipses of the satellites of Jupiter." Principia Although that alone is high contrived and nothing to do with time, it doesn't end there. Huygen's notion that the motion of the Sun through the Zodiac is the same as the Earth's motion through the same provided Sir Isaac with the notion for orbital periods and his skewed notion of retrogrades - " That the fixed stars being at rest, the periodic times of the five primary planets, and (whether of the sun about the earth, or) of the earth about the sun, are in the sesquiplicate proportion of their mean distances from the sun." Newton Of course Kepler's approach has no such ghastly feature and it has nothing to do with orbital speeds or geometry other than a proportional look at orbital periods for different planets reduced to averages - "But it is absolutely certain and exact that the ratio which exists between the periodic times of any two planets is precisely the ratio of the 3/2th power of the mean distances, i.e., of the spheres themselves; provided, however, that the arithmetic mean between both diameters of the elliptic orbit be slightly less than the longer diameter. And so if any one take the period, say, of the Earth, which is one year, and the period of Saturn, which is thirty years, and extract the cube roots of this ratio and then square the ensuing ratio by squaring the cube roots, he will have as his numerical products the most just ratio of the distances of the Earth and Saturn from the sun. 1 For the cube root of 1 is 1, and the square of it is 1; and the cube root of 30 is greater than 3, and therefore the square of it is greater than 9. And Saturn, at its mean distance from the sun, is slightly higher than nine times the mean distance of the Earth from the sun." Kepler It is just one of those unique times in history where neither the celestial sphere enthusiasts nor the experimental theorists have any interest or capacity to deal with the very narratives they promote although they are bound together in a mutual self-serving purpose. It is terrible to see astronomy destroyed for so little gain but the bulk of the blame doesn't go to the theorists but rather those small minded people who consider the celestial arena as a telescopic hobby and identification.. |

That should be the lamentable empiricist tendency of switching the Sun around the Earth is equivalent to the Earth around the Sun by using the background stars as a gauge -
"Here take notice, that the Sun or the Earth passes the 12 Signs, or makes an entire revolution in the Ecliptic in 365 days, 5 hours 49 min. or there about, and that those days, reckon'd from noon to noon, are of different lenghts ; as is known to all that are vers'd in Astronomy." Huygens This was a point of departure for a lot of mischief and especially the notion that the observed motions of the planets are transferred to a stationary Sun rather than the proper principles based on a moving Earth. Poor proofreading but that is my only failing. |
