Space is the boundless, three-dimensional extent in which objects and events occur and have relative position and direction. Physical space is often conceived in three lineardimensions, although modern physcists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spcetime. In mathmatics one examines "spaces" with different numbers of dimensions and with different underlying structures. The concept of space is considered to be of fundamental importance to an understanding of the physical universe although disagreement continues between philosphers over whether it is itself an entity, a relationship between entities, or part of a conseptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the timaus  of plato, in his reflections on what the Greeks called khora, or in the Physics of aristotle in the definition of topos, or even in the later "geometrical conception of place" as "spacequa extension" in the Discourse on Place of the 11th century Arab polymath alhazen. Many of these classical philosophical questions were discussed in the Renaissance and then reformulated in the 17th century, particularly during the early development of classical mechanics. In Issac Newton's view, space was absolute - in the sense that it existed permanently and independently of whether there were any matter in the space
