Classical mechanics or celestial motion reduced to terrestial
ballistics was formatted with a contrived view that geocentric and
heliocentric orbits are equivalent.This equivalency is the basis for
mean Earth/Sun distances and involves a meshing of axial rotation with
orbital motion as a single sidereal motion.

It may not be so easy to look ahead but with the Newtonian view it
becomes impossible and would have been impossible even in his era.
The problem is not in the trifles of which you are

He took flight on the back of an astronomical crow,he determined mean
orbital distances through Flamsteed's erroneous assumption for axial
rotational/stellar circumpolar equivalency.The purpose Flamsteed
sought the equivalency was in determining terrestial longitudes by way
of celestial sphere positions,Newton simply switched it to an orbital
equivalency.

Sounds great until it is now realised that orbital variations exist
and cause ice ages which in turn affect geological features and leave
a recorded history of the geological and astronomical history of the
planet.With Newton's mechanical view there is no mechanism for the
change from less elliptical to more elliptical in terms of either mass
or acceleration (insofar as Kepler's second law applies regardless of
the degree of the elliptical motion) notwithstanding that the template
for mean Earth/Sun distances is already wrong.

This goes to prove my point that behind the supposedly highly
contentious conceptual differences arising from the early 20th
century,all sides will run home to momma and defend Newton.The only
verification worthwhile is actually going outside and determining that
the Earth is rotating in and out of its orbital shadow rather than
sunrise and sunset which would be valid under the Newtonian scheme.The
early 20th century concepts basically reduced this quasi-geocentric
view further to homocentricity and it remains stuck there.

Copernicus,Kepler and Roemer never needed an aether,it is useless for
investiagating astronomy and the underlying geometry between observed
planetary motions and their actual motions.The difficulties arising
from Newtonian astronomical framework was causing great difficulties
in the mid 19th century in determining the Sun attracting the Earth
and the Sun illuminating the Earth but only in the 1930's with
galactic observations making their appearance could questions of
Keplerian motion really be answered.

Geologists don't do 'thought-experiments',they recognise the Earth's
geological evolutionary history embedded in rocks and attempt to work
out how events unfolded through surface features.Because astronomical
records of orbital variations show up in geological records it is now
possible to achieve cosmological modelling by incorporating the
mechanism for orbital variations as variations in the solar system's
motion from a cyclical 100 000 year variation from an inner and outer
galactic orbit.
How dumb relativists look by imagining that as you look into space it
represents the astronomical 'past' other than the
geological/astronomical past embedded in sedimentary laying in rocks.

Your argument is with those who determine that all things must be
filtered through an experiment whereas the conceptions of
geological/astronomical history requires only the ability to make
correct correlations.Steno in the 17th century determined that
sedimentary layers which are observed to be vertical on the side of
mountains were once in geological times to be horizontal,this type of
reasoning can be refined to the point with sedimentary classifications
without disturbing the underlying principle.Relativity is the symptom
of a disease brought on by Newton for the underlying astronomical
principles on which he formulated his ballistic agenda does'nt
exist,the rotation rate of the Earth is wrong,he combines axial and
orbital motion,the stars are not fixed and what have you.

Suit yourself for ultimately you assume that they don't work at higher
velocities and that makes you a relativist plain and simple.Orbital
variations such as Mercury's or artificial trajectories such as
Pioneer 10 have a better astronomical setting after the motion of the
solar system around the galactic axis was discovered but you remain
stuck in the era where none of this was known.

I am satisfied that as long as you remain looking for experimental
evidence you are going nowhere for like geology,astronomy can only be
accomplished in principle insofar as the time and distance scales
reflect the enormity and magnificence of the cosmos.Whether the
effects of finite light distance from distant supernova and their
parent galaxies or the actual relationship between the observed
position of galaxies to our own and to each other in determining
structure and motion,none of it can be discerned by the claustraphobia
of lab top experiments or silly opinions that mascerade as
'thought-experiments'.

You have no reason to complain,your views will always receive an
airing as the methods and ends to which you tend are the same.In
strenghtening the areas of the relationship between geology,terrestial
evolution,climatology and astronomy,people have found a better way to
appreceate the connection between humanity and its surroundings,you
can wax lyrical on final theories and how complicated it all is but
namedropping and labelling is such a poor excuse,this being now the
sole purpose of physics and physicists.

You belong to a different era even though it still remains firmly
entrenched in society.The horror of the Newtonian labyrinth was
superceded by the early 20th century one where men call out to each
other from dead ends that have grown in number exponentially in recent
times.The way out is always an option and not that difficult a step to
take,either by recognising the Newtonian astronomical template to be a
quasi-geocentric one or more productively to incorporate the solar
system's motion around the galactic axis and its influence on
heliocentric planetary orbital motion.
