If each particle of the lunar were attracted with the same force, regardless of its location, on the surface or inside the planetary body, plus the gravitational field itself, which would hold them all together, then no external forces would violate the correct shape of the moon ball, according to the law of isostasy. But in reality, the Moon has an elongated shape, and moreover, in the direction of the Earth. Isn't this suspicious? Therefore, not all lunar matter is equally and not with the same force attracted to the Earth.

As you can see, some part of the lunar matter is attracted more strongly, while the other is weaker. From this it becomes clear that part of the substance, which is subject to the greater force of gravity, should be closer to the source of attraction, and the other, on the contrary, farther away. This, in turn, suggests the inhomogeneity of the substance of the lunar ball, and a special placement both inside and on the surface. In this regard, different ideas may arise, correct and incorrect. However, we cannot refer to such an assumption that the side of the Moon we see consists of heavier elements such as iron, and the other side - with lighter silicates. This is denied by many facts of observation, research and common sense about the structure of planetary bodies such as the Earth. This means that there can be only one conclusion here: it all depends on the innermost structure of the Moon, which creates isostasy on the processes during the course. But since it is most likely assumed that the Moon as a planetary body is similar to the Earth's internal structure, then again the question refers to the lunar core. It should be the most dense mass and at the same time the source of the lunar attraction. And if so, then it is that part of the lunar substance on which the earth's gravity has the greatest influence, that is, it attracts with greater force.

The Moon is not dead. It is a living planet. This is evidenced by a sufficient number of irrefutable facts. The substance inside the Moon is a hot mass and no less temperature than in the deep zones of the Earth. In addition, according to radar studies, it was revealed that the increase in temperature with depth is quite fast - about one and a half degrees per meter - many times faster than on Earth. This information most of all concerns a separate question about the structure of the selenosphere and the inner zones of the Moon. But this example is used as another argument in favor of the warmed inner part of the Moon.

We can only guess in which state is the substance that makes up the lunar core. It will be in a viscous or liquid state, so far it does not matter in this study. The fact is that it does not represent a stationary petrified mass, strictly in the center of the planet. It is possible that the core of the Moon is also in a solid state, like that of the Earth, but the inner shells that envelop it are not cooled or petrified and they are in a mobile state (and so it floats freely). In short, the lunar core is in an environment in which it can move from the center of the lunar ball in some direction under the influence of external forces of attraction - the forces of attraction of the Earth. (But the mechanism of displacement itself is not clear).
