A myth from ancient China. The story tells a woman who lives on the moon. But the astronauts have never seen her. Because she lives in the interior of the moon.

The density of lunar rocks brought back by Apollo’s lunar landing plan is much larger than that of the Earth’s rocks. It can be seen that the density of the moon is astonishing. If we speculate according to this phenomenon, the center of the moon should be a core composed of large-density matter.

Considering the distance in between center and surface of the Lunar will be short than earth. Coupled with its total mass, gravity is much larger than we think. However the gravity of lunar merely 1/6 from earth. It seems that the lunar gravity has nothing to do with its density and mass. This shows what? This only shows that the moon is a huge hollow sphere.
