EARTH'S MASS, DENSITY, AND MOMENT OF INERTIA. To learn what the earth is made of, our first constraint is its density (mass / volume). We find its mass from the acceleration of gravity g. The universal law of gravity says that the force F betwen objects M and m.
The moment of inertia of the Earth indicates that there is a concentration of mass around the center, seismic data has also shown that the center of the Earth is a solid sphere. This is interesting, because the hollow Earth theory proposes the idea of a central sun.here really is some mind blowing information that suggests the Earth could actually be hollow. Our current understanding about the makeup of Earthâs core is a theory, based on assumption that is taught as fact. The evidence for the composition of the Earthâs core is decent, however indirect.
