G'day Martin. good to have your input. Paul, if you want some info where  your 
peer group gives support to the probability of my aether, this might be worth a 
read. 

I am not sure we can accept as gospel "The Lense-Thirring Effect does in fact 
predict rotational inertial dragging of frames in the vicinity of a rotating 
body, and it is an effect that has been experimentally confirmed. " In fact 
most of the selected paragraphs I offer below from Wikipaedia, (admittedly not 
gospel) merely add more confusion as to what is reality and what is 
imagination./

Take this , 
"The main consequence of the gravitomagnetic force, or acceleration, is that a 
free-falling object near a massive rotating object will itself rotate. This 
prediction, often loosely referred to as a gravitomagnetic effect, is among the 
last basic predictions of general relativity yet to be directly tested. " 

You will notice in the selections below that the term "gravitomagnetism"  is an 
analogous term, coined no doubt to infer there is a gravitational field similar 
as in a magnetic field, but not proven. Yet everything becomes "out of this 
world" when space time is invoked. Reading between the lines, it is inferred 
that the DRAG IS NOT due to NEWTONIAN INERTIA but time shifting (time travel) 

Even though I would like to believe in it, and it is certainly possible, this 
does not make it true. But Scripture certainly makes it probable...  

From Wiki, Lense-Thirring effect

"Albert Einstein's theory of general relativity predicts that rotating bodies 
drag spacetime around themselves in a phenomenon referred to as frame-dragging. 
The rotational frame-dragging effect was first derived from the theory of 
general relativity in 1918 by the Austrian physicists Joseph Lense and Hans 
Thirring, and is also known as the Lense-Thirring effect.[1][2][3] More 
generally, the subject of field effects caused by moving matter is known as 
gravitomagnetism.
Lense and Thirring predicted that the rotation of an object would alter space 
and time, dragging a nearby object out of position compared to the predictions 
of Newtonian physics. This is the frame-dragging effect. The predicted effect 
is incredibly small - about one part in a few trillion - which means that you 
have to look at something very massive, or build an instrument that is 
incredibly sensitive.

The frame dragging predictions of general relativity have been confirmed to a 
20% accuracy using the LAGEOS sattellites.[citation needed] The Gravity Probe B 
experiment is currently under way to experimentally measure the amount of 
frame-dragging to a much greater accuracy." end quote. 

I am talking here with HC or GC in mind. Meaning it does not influence my 
reasoning even if it does change values/quantities , which for this discussion 
is irrelevant

Now there is much to be controversial in the above quote, all being 
theoretical. Do we accept Einsteins General relativity? dragging space time? or 
gravitomagnetism? 

Might not the miniscule forces measured be caused by some other aberation in 
gravity, similar in effect to tides, which also give the illusion of being 
dragged by the moon, whereas they are not dragged. Tidal currents, as such, 
flow from both east and west. 



Definitions follow:

spacetime

In physics, spacetime is a mathematical model that combines space and time into 
a single construct called the space-time continuum. Spacetime is usually 
interpreted with space being three-dimensional and time playing the role of the 
fourth dimension. According to Euclidean space perception, our universe has 
three dimensions of space, and one dimension of time. By combining space and 
time into a single manifold, physicists have significantly simplified a good 
deal of physical theory, as well as described in a more uniform way the 
workings of the universe at both the supergalactic and subatomic levels.

(Now that, if even close to true, supports what I have said about the aether 
being an effect of the fourth dimension.)

 
Two-dimensional analogy of space-time distortion. The presence of matter 
changes the geometry of spacetime, this (curved) geometry being interpreted as 
gravity. Note that the white lines do not represent the curvature of space, but 
instead represent the coordinate system imposed on the curved spacetime which 
would be rectilinear in a flat spacetime
General relativity (GR) [also called the general theory of relativity (GTR) and 
general relativity theory (GRT)] is the geometrical theory of gravitation 
published by Albert Einstein in 1915/16.[1][2] It unifies special relativity 
and Sir Isaac Newton's law of universal gravitation with the insight that 
gravitation is not due to a force but rather is a manifestation of curved space 
and time, with this curvature being produced by the mass-energy and momentum 
content of the space-time. General relativity is distinguished from other 
metric theories of gravitation by its use of the Einstein field equations to 
relate space-time content and space-time curvature.

General relativity is currently the most successful gravitational theory, being 
almost universally accepted and well supported by observations. The first 
success of general relativity was in explaining the anomalous perihelion 
precession of Mercury. 

Didn't someone on this list show that this last re Mercury was pure luck, that 
the theory failed in many other similar instances tested. In other words a 
direct act of deceit. So much for honesty in science  

 Gravitomagnetism (sometimes Gravitoelectromagnetism, abbreviated GEM), refers 
to a set of formal analogies between Maxwell's field equations and an 
approximation to the Einstein field equations for general relativity, valid 
under certain conditions. For instance, the most common version of GEM is valid 
only far from isolated sources, and for slowly moving test particles

This approximate reformulation of gravitation as described by general 
relativity makes a "fictitious force" appear in a frame of reference different 
from a moving, gravitating body. By analogy with electromagnetism, this 
fictitious force is called the gravitomagnetic force, since it arises in the 
same way that a moving electric charge creates a magnetic field, the analogous 
"fictitious force" in special relativity. The main consequence of the 
gravitomagnetic force, or acceleration, is that a free-falling object near a 
massive rotating object will itself rotate. This prediction, often loosely 
referred to as a gravitomagnetic effect, is among the last basic predictions of 
general relativity yet to be directly tested. A group at Stanford University is 
currently analyzing data from the first direct test of GEM, the Gravity B 
satellite experiment. Frame-dragging is often mentioned as a gravitomagnetic 
effect, but the Lense-Thirring effect (precession) may be a more appropriate 
example.

A fictitious force, also called a pseudo force[1], is an apparent force that 
acts on all masses in a non-inertial frame of reference, e.g., a rotating 
reference frame. The force F does not arise from any physical interaction, but 
rather from the acceleration a of the non-inertial reference frame itself. Due 
to Newton's second law F = ma, fictitious forces are always proportional to the 
mass m being acted upon.

Look a force is a force if it is apparent, meaning observed..  Why call it 
ficticious??  Mama Mia...  Oh I get it ..  Its a mamathmatical force ..  An 
extra thrown in to balance the equation...  I like it..

    I guess your weakness in physics shows up here again, the Earth's 
acceleration (revolution) does not influence the period of its satellites 
either.





  That, Paul, is what's known as an "oops" on your part. The Lense-Thirring 
Effect does in fact predict rotational inertial dragging of frames in the 
vicinity of a rotating body, and it is an effect that has been experimentally 
confirmed.  While the amount is infinitesimal for a mass as small as the Earth 
(assuming it to be rotating, which I disavow), it is nonetheless non-zero.  A 
rotating body DOES have a mechanical influence on the periods of objects around 
them -- it's generally too tiny to detect.




  So, while you might be correct on raw Newtonian grounds, in the absolute 
empirical scheme of things the only thing exposed by your post is your own 
weakness in physics. True, the magnitudes of the Lense-Thirring Effect likely 
don't affect your primary argument, BUT your blanket statement goes too far in 
asserting zero influence.




  Don't think to say that Newton "is good enough." Long's 1970 determination of 
G using a Cavendish torsion balance, set up with precision elemental rings, 
showed deviations in the value of G (based on Newtonian theory) of 0.37%.  That 
means Newton is off by a whoping 1 part in 300, and this error was readily 
detectible in an earth-bound laboratory.  Einsteinian theory can't explain that 
anomaly either, so GR is likewise an unreliable codification of gravitation. 




  That said, I'm still interested in hearing from Robert as to what HE meant by 
his comment (perhaps it had something to do with accounting for elliptical 
orbits, which would entail accelerations/decelerations if they were assumed to 
be circular, or he sees something else entirely that needs to be factored in...)
