First, it should be specified, at least approximately, what it means. According to a definition "apart from time, space is the basic form of existence of matter." Along with the advances of science, different ideas regarding the character of space develop. Can space be considered a self-existing, independent, and transcendent element or is it an attribute (like time) of the existence of matter? Plato considered space as an element between the world of ideas and the world of objects. Plato's ideas, like the ideas of atomists, who believed in the existence of atoms in empty space rejected Aristotle who connected space with matter and sometimes with movement.
