Default Newton's absolute/relative space and motion

The people in the early 20th century cobbled together a story as to what they thought Newton's designations of space and motion represented even though he was explicit in partitioning what he viewed as relative or apparent motions from true and absolute motions of the same objects. The discrimination between apparent motions and what belongs to a celestial object itself and what is merely a consequence of changing perspectives between two moving objects is the bread and butter of high end astronomy where cause and effect take center stage yet Sir Isaac basically butchered this process to suit his own ideology which remains a disruptive failure even to this day.

The idea of retaining the celestial sphere background stars in an RA/Dec framework and then creating an absolute/relative space and motion into which positions and motions of celestial objects are inserted is cruel and its only effectiveness is in getting the wider population to believe it has some merit.

'PHÆNOMENON IV.'
"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...This proportion, first observed by Kepler, is now received by all astronomers; for the periodic times are the same, and the dimensions of the orbits are the same, whether the sun revolves about the earth,or the earth about the sun." Newton

So take heed in what Kepler actually stated when he discusses the correlation between orbital period and distance from the Sun insofar as it was not written as a 'law' and neither can it be converted into one -

"The proportion existing between the periodic times of any two planets is exactly the sesquiplicate proportion of the mean distances of the orbits, or as generally given,the squares of the periodic times are proportional to the cubes of the mean distances." Kepler

Or

"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

I read these early 20th century conceptions of Newton and they are quaint and a long way from 'revolutionary',they may look so to people who are used to making wide sweeping gestures at the celestial arena but the nitty gritty of Newton's approach doesn't allow for these liberties -

I really wish empiricists were interested in their own system so at least they could move forward in a productive way without having to be up front about it. There are no prizes for figuring out what Sir Isaac was trying to do but there is an incredible satisfaction knowing what he did try to distort and why it doesn't work.

Astronomy is the finest visual storytelling rather than the imaginative vehicle those guys since Newton made it out to be,in the early 20th century they merely encrusted the celestial sphere shell of the RA/Dec framework in more jargon along with the later 'no center/no circumference' novelties such as big bang/black hole.

Since the emergence of the visual side of the internet,I have seen the nature of my involvement change from arguing over the texts which make up the historical trajectory of the astronomical narrative including the disruptive mutations inserted by followers of Newton to a more productive and creative venture. It is now possible to tell a story on any given topic using images and visual footage including where the damage was done by trying to skew retrograde resolution to an alternative perspective and its appearance as absolute/relative time,space and motion.

Only with the confines of that hard shell of celestial sphere indoctrination can you maintain what is effectively a misguided scam even though I do appreciate that those early 20th century guys tried to escape the clockwork solar system which is a consequence of the equatorial coordinate system modeling however things have changed within the last decade with the development of a more visual internet which allows observers to appreciate long term events in a condensed form which in turn makes for an exciting era in astronomy.

The first computer innovators did get a glimpse of the bigger picture and so I see the bigger picture with astronomy and the new tools which aid its promotion and especially as it makes all things new.The ability to partition inner and outer retrogrades with visualization techniques makes the initial effort so rewarding even at this early stage where I can cobble together images from different sources to create a story however I would look forward to a time when people would dedicate imaging towards making these stories more understandable.

The Newton/Einstein story is built on the equatorial mount,homocentricity as a matter of fact, and it shows up in the way you make descriptions of Venus and Jupiter without the slightest sense of how to distinguish them to the Earth,to each other and to the stellar background -
