Abstract

 From ancient Greece to modern times, philosophers and scientists have developed a history of thought processes that seek to find the cause of gravity that causes objects to fall. Today, Einstein explained the phenomenon of gravity that the curved space was gravity. General Relativity expresses the phenomenon of gravity very strictly, but its origin and generation mechanism of the force of gravity are not well explained; the explanation of reason is insufficient why the force of gravity is generated when the space curves. In this paper, curved space, or curvature of space, is purely mathematical geometric quantities, but with the help of continuum mechanics, it is shown that they are related to actual forces. Given a priori assumption that space as a vacuum has a physical fine structure like continuum, it enables us to apply a continuum mechanics to the so-called “vacuum” of space. Applying the continuum mechanics of space to General Relativity, the mechanism of gravity has shown as one possibility.
