Many different explanations are found in general literature and the Internet for the phenomenon that the moon is always facing the Earth with the same side. All of the websites pretend to know one or the other qualitative effect. Terminologies that are used as: tidal force, tidal lock, the tidal bulges, etc... don't mean anything by themselves. None of the writers explain it quantitatively nor qualitatively in a satisfactory way.
In this paper, I will quickly overview the most common theories and evaluate them. I show that there is not any gravitational possibility left for explaining this phenomenon. Further, I will explain the origin of the oscillations of the moon that makes the Moon showing about 60% of its surface instead of 50%. Also this can only be originated by non-gravitational physical laws.
