This article expounds the materiality of time and space from the perspective of relativity theory. Time and space are the attribute of the materials. Time and space in being depend on the existence of the materials. Their character will change if the material's movement state alters. Time can't pass eternally if it stands isolated from the material or material's movement. Space also is related to the material and material's movement,and can't extend infinitely.
