Euclidean Analysis of Moon Rotation

The standard model of Moon rotation is universally accepted in astronomy.
This site does not challenge that model.

GEOMETRY

Instead, it examines how the model is interpreted, and shows that the usual interpretation contradicts elementary Euclidean geometry.

The article “The Model” presents a direct examination of the standard Moon rotation model using only Euclidean geometry.
it presents a purely geometrical analysis.
No reference frames, forces, or dynamical arguments are introduced at this stage.

FROM GEOMETRY TO PHYSICS

As regards the Moon itself, The article “Rotation” relies entirely on and draws conclusions from the article “The Model”.

DYNAMICS

The article “Libration” presents a Python simulation of the behaviour of the Moon based on the standard model.
In a first mode, it treats the libration.
In a second mode it treats purely the rotation. It confirms by means of dynamics the main conclusion of the article “Rotation” obtained by means of geometry.

LANGUAGE

If a selector is present at he upper part of an article, you can switch language at any time using the selector.

All scientists believe that, in the universally accepted model of the Moon, the mathematical disk representing it rotates on its axis. The contrary will be formally demonstrated below using geometry.

The goal of the article is not to obtain any validation of the demonstration, since it is irrefutable, but rather to create a core group of challengers. To join them, simply leave a comment at he bottom of the present page. Please include the method you deem most suitable for reaching a widespread acceptation of the demonstration (or an equivalent one).

I will then send you by email the password that locks the other articles on the present site. These articles deal with the behavior of the Moon itself and call for a debate based on the fact that the disk does not rotate on its axis.

Demonstration

Regardless of its presentation, the universal model is characterized by a disk rotating around a fixed point while maintaining three points aligned.

The figure above presents such a model, provided the curved arrow on the disk is removed (unlike the green arrow, the red one is not part of the model because it results from a misinterpretation). It is taken from a NASA’s video which was available on its website: https://svs.gsfc.nasa.gov/4709 (unfortunately the site is not accessible by now).
It shows eight snapshots from the video taken at regular intervals during one revolution, to which we added (only once to avoid overloading the figure) the line (D) supporting the three points:

The straight line (D) rotates around the fixed point E. Therefore, according to Euclidean geometry, it cannot rotate around a second point like M. Consequently, the segment MN does not rotate around M. Therefore, the disk attached to the segment does not rotate around its center M.

Note: Among the various versions of the universal model, we should also note the animated figure on the left of the Wikipedia page https://en.wikipedia.org/wiki/Tidal_locking, or the one on the left side of the video on the NASA page https://science.nasa.gov/moon/tidal-locking/. However, the latter bears the following warning: “due to the lapse in federal government funding, NASA is not updating this website”.
