Space is the boundless extent that exists into the three dimensions in which objects and events have relative position and direction. Physical space is generally conceived in three linear dimensions, however, modern physicists usually consider it with time to be part of a boundless four-dimensional continuum referred to as the spacetime. The concept of space is considered to be of fundamental importance in order to draw an understanding of the physical universe. However, disagreement continues between philosophers and scientists over whether it is a part of a conceptual framework or is it itself an entity or a relationship between entities. Debates that concern the very nature of the space, its essence and the mode of its existence date back to antiquity, namely, to treatises like the Timaeus of Plato, or Socrates in his reflections on what the Greeks called khora which translates to the "space" only, or in the Physics of Aristotle (Book IV, Delta) in the definition of topos which translates to place. Many of these classical philosophical questions were discussed and debated upon in the Renaissance and then reformulated in the 17th century, particularly during the early development of classical mechanics. In Isaac Newton's view, space was absolute, that means, that it existed permanently and independently of whether there was any matter in the space. In the 19th and 20th centuries many mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as curved rather than flat. According to theory of general relativity proposed by none other than Albert Einstein, space around gravitational fields deviates from Euclidean space. Experiments based on the general relativity have confirmed that non-Euclidean geometries provide a better model for the shape of space.
