There are so many things wrong here it is difficult to know where to start.

As I have mentioned on numerous occasions creationists and their subset, flat earthers and geocentrists, don’t seem to understand the false dichotomy fallacy.
The common thread between your links falls into the “Einstein is wrong” category, and does not provide tacit support for geocentricism or a flat earth.

Lorentzian relativity formulated by Henrick Lorentz makes the same predictions as Einstein’s special of relativity, the difference being it requires the existence of an aether but not a geocentric model.
The aether was considered to be in an absolute frame of reference and stationary, although later theories attempted to rescue the idea by proposing the aether was being dragged along as the earth orbited the Sun.
The so called “aether wind” was due to the earth’s motion in space not the earth being stationary and the aether moving.
If aether existed, our modern day cavity type interferometers which are billions of times more sensitive than the interferometers used by Michelson and Morley would detect continuous changes in the velocity of the aether wind.
Which do you think would be a more logical explanation; the earth moving in an elliptical orbit around the Sun where its orbital velocity changes with position as demonstrated by Kepler’s laws of planetary motion or some unexplained variations in aether wind velocity the existence of which is disproven by the null results of very interferometer measurements themselves?

Since your links are very biased with the “Einstein is wrong” narrative here is the full picture of why the special theory of relativity is mainstream and all other competing theories including aether are not.

Then there are the results of the Hafele-Keating experiment.
The time difference between the clocks on the plane and the stationary earth bound clocks is a combination of general and special relativity effects.
The general relativity effect is where the planes do not travel in straight lines but in curved trajectories in accelerated frames of reference and subject to gravitational time dilation along with the earth based clocks according to Einstein’s equivalence principle.
For the special relativity effects, the clocks on the plane are moving relative to the centre of the Earth which is the inertial frame and therefore undergo kinematic time dilation according to the Lorentz transformations of special relativity as are the earth based clocks which are also moving relative to this inertial frame at the earth’s centre.
Aether is not a requirement.

A specific test in the table shown in my previous post which destroys the idea of a stationary earth is stellar aberration highlighted in the column.

SR_1.jpg

In 1727 the astronomer James Bradley observed stars appeared to move in small circles on to the fixed astronomical coordinates with respect to the earth.
The diameter of these circles was around 41 arc seconds and was caused by the velocity of the earth as it orbited the Sun.

If the earth was stationary the light from a star directly overhead would go into the telescope as illustrated in a straight vertical line as illustrated (a).

Bradley.jpg

In (b) the earth (and telescope) are moving to the right at a velocity v.
In order for the light not to hit the sides of the telescope tube, it would have to be tilted at an angle α, for the time interval Δt, the light travelling the vertical distance cΔt from the objective lens to the eyepiece where c is the speed of the light.
During the same time interval, the telescope has moved vΔt to the right.

Six months later since the earth orbits the Sun, the direction is reversed and the telescope moves to the left; for the entire orbit of one year a cone of aberration is swept out of angular diameter 2α as shown in (c).

While this test was used to refute aether attached to the earth and being dragged by it, where the earth is stationary relative to the aether, a geocentric model would also result in stellar aberration not being observed.

Why then did you quote him at all ? To show something you don't agree with, or you do agree with, or some other reason ?
Since there's millions of books that are not Scripture, none of them, not one , needed to add to nor to take away from Scripture,
nothing should be allowed to add to , nor to take away from , God's Own Word, eh?

Well if you would have seen the whole postings made in this discussion. You would have seen a member ask for proof that Augustine believed in a works based salvation.

So i posted some of Augustine's writings on the subject.

Actually, as Einstein et al mathematicians proved over the last century,
that is only from your perspective. (and in case someone thinks it ever concerns flat earth , no, it has nothing to do with flat earth at all).
Stellar aberration is a matter of my perspective?
So if a thousand people of different persuasions each using a separate telescope and CCD all found stars to move in small circles at a diameter of 41 arcseconds then how is it a matter of perspective when they all observe and measure the same thing as I would?

If this is some feeble attempt to debunk heliocentrism, you should try harder by proposing your own hypothesis to explain this observation.

Blimey, to think that people really believe we live on a flat earth!!! Truly inconceivable....
It is interesting to know that the ancient Babylonians and Greeks knew the earth was a sphere, five centuries before Christ.

Let me, let me!
Your enthusiasm is inspirational. (I assume you are referring to the entire website.) To determine (in part) your relevance to Plane Geodesy from the perspective of its overall content (as opposed to a somewhat specialized niche), please forward us your curriculum vitae (including a list of your affiliations) for our review. Also, please include your fee structure. You can email said documents and related information to info@planegeodesy.com. We will get back to you. Thank you for your interest in Plane Geodesy. Take care.
