The ideal way to conceive this is to leave the conclusion above
seperate from the data.The great astronomers plotted the positions of
the planets against the stellar background noting 'retrograde' motion
and drew conclusions froma stationary Earth or an orbitally moving
Earth (Copernicus).

Nobody ever said anything about jumping to the Sun to explain the
observed motions of the planets,only Newton did -

" For to the earth planetary motions appear sometimes direct, sometimes
stationary, nay, and sometimes retrograde. But from the sun they are
always seen direct," NEWTON

Now you have the basis for Newtonian absolute/relative space ,a concept
based on the wrong idea of what retrogrades are and how they are
resolved.

Are you not delighted for this early Christmas present in terms of the
relief in actually knowing what Newton did wrong.As far as his
maneuvering goes that is the easiest to understand but wait until you
see what he did with absolute/relative time !.

Ah,you are all his disciples anyway and would rather harp on about the
guys in the early 20th century being right or wrong.

In the solar system, the centroid is alway within the sun or very close
to the Sun. Therefore, viewing from the from the centroid of the solar
system(or from the Sun approximately) would eliminate retrograde
motion. This agrees totally with Newton's law.


Incorrect,retrogrades are simply the plotted motions of the planets
against the stellar background,the Ptolemaic astronomers drew
conclusions of periodic looping motions of the planets from a
stationary Earth while Copernican astronomers see,I repeat,see the
orbital motions of the planets around the Sun from an orbitally moving
Earth -

Nobody ever talked of jumping to the Sun except Newton to resolve the
observed motions of the planets and the information loss by doing so is
catastrophic.You do however get your absolute/relative space as Newton
would have retrogrades and their resolution.

I can identify through a precise Keplerian representation where Newton
,and subsequently his disciples,jumped the tracks by not drawing the
distinction between plotted data and the conclusions drawing from that
data.

You do not need laws to determine what is correct and what is not,you
just need subtle judgements and with time lapse footage now availible
it is easier than ever to appreciate what Copernicus did and how his
conclusions based on seeing planetary orbital motions from a moving
Earth provide the working principles of the later Keplerian and
Roemerian refinements.





Relativity is different. It has an absolute centre. Precession of the
perihelion of Mercury can be explained perfectly when the Sun is the
absolute centre. If the Sun and Mercury are rotating around the
Mercury-Sun centroid then it would be difficult to explain the
"Precession of the perihelion of Sun".

If that the Sun does not have the Precession then the centroid of the
Sun-Mercury system would not always stay at the same place. That
violates Newton's first law.


I do not deal in 'ifs' I deal with geometric certainties and the
Newtonian mutations of what retrogrades are and how they are resolved
do not measure up to even Ptolemaic astronomy ,in short, the celestial
sphere geometry concepts of Newton are sub-geocentric.

" For to the earth planetary motions appear sometimes direct,
sometimes stationary, nay, and sometimes retrograde. But from the sun
they are always seen direct," NEWTON

Merry Christmas !
