Space over time

There are dozens of definitions of space depending on the context in which the word is used, but none is satisfactory to describe the nature of space.
The notion of space has evolved over time, the concept is linked to the history of mathematics and physics. For several millennia, intuitive and familiar, this concept has been expanded to become extremely complex.
How has evolved the notion of space over time until today?
For primitive peoples, the concept of space does not exist, according to ethnologists, the center of the world is the center of the village.
In ancient Greece, that of Pericles (around the year -495) space is a limited range occupied by the bodies. At the time of Plato (-428 -348) was born philosophy and science, and the concept of space is that of the void, the receptacle in which everything exists (Plato's Timaeus). For Aristotle (-384 -322), the space is the sum of the places. The first formal classical notion of space, emerges with the geometry of Euclid (around -300). Space is "geometrized".
During the Islamic Golden Age (≈1250 to ≈750) and until the end of the Middle Ages, the concept of space is that of Euclid. The Islamic Golden Age began with the translation of scientific works of Greek origins, Indian, Persian and Syriac, to Arabic.
During the Renaissance, the space becomes more abstract, it is modified by painters who trace in their paintings, projections on a plane, projective geometry appears.
In the 17th century comes the Newtonian revolution which marks the beginning of modern science.

Newton express the properties of a physical space and a physical time. Therefore, all phenomena will take place in a space unchangeable, absolute, and in a time that always flows in the same direction.
Today in black holes, space and time merge.
The space has evolved from a philosophical concept to a mathematical and physical concept.
Currently, the space refers to the geometry, time itself geometrized is the fourth dimension of space. The time represented as the continuous succession of moments on a straight line, is a one-dimensional space.
The special relativity of Einstein combines these two entities as spacetime, a four-dimensional space.
In Euclidean geometry objects are idealized. The point, right, polyhedron, conic sections and their measures are length, area, volume, appear in an intuitive space.
Today the Euclidean straight line became a mathematical manifold of one-dimensional, plane a manifold of two-dimensional, Euclidean space a manifold of three dimensions. These three manifold are part of other mathematical manifolds of n-dimensions.
These are the 19th century mathematicians such as Carl Friedrich Gauss (1777-1855), Bernhard Riemann (1826-1866), János Bolyai (1802-1860), Johann Heinrich Lambert (1728-1777), who showed that besides this Euclidean space, there were others n-dimensional spaces.
At that time an additional property is attributed to the space.

At the end of the 19th century, developments in mathematics will lead to redefine the notion of space.
The space now has a curvature, zero, positive or negative and can vary from one point to another in space. For example, the straight line and the plane have a constant curvature equal to zero, the sphere has a constant curvature equal to 1/R², in other words the curvature of the sphere is greater as the radius is small.
But the curvature is not simply described as a number but by a tensor, a complex mathematical object that can vary from one place to another in space.
Bumpy surfaces have a curvature at each point as the surface of an ocean at each location there is a different curvature.
In the 20th century Einstein adds time to space.
The concept of spacetime was introduced by Hermann Minkowski (1864−1909) in 1908 in a mathematical presentation on the geometry of space and time as it was defined by the theory of relativity of Albert Einstein (1877−1953).
Spacetime is a 4-dimensional manifold that has a variable curvature from one place to another. This curvature is gravitation. All objects in the space feel this curvature. "So between Earth and the Moon there is geometry."
The differential geometry of Bernhard Riemann (1826−1866) will pave the way for non-Euclidean geometries, which will allow Einstein to develop the theory of General Relativity that identifies the gravitational effects on the curvature of space. Therefore, the global topology of the space will be the subject of much research. Mathematicians are still complicate the notion of space. The space now has n dimensions, plus it is multiple, each space belongs to a class of space and the curvature exists in all spaces.

The other innovation of space is expressed by the non-commutative geometry developed by Alain Connes in 1985. In a non-commutative space, the notion point disappears, the very nature of space prohibits locating a particle. With quantum mechanics, a microscopic system, an atom for example, has coordinates, such as position, which no longer commute. In these spaces, the algebra of coordinates no longer obeys the commutative rule (x + y = y + x).
When you want to know where there is a particle results in an uncertainty relation. The position of the particle can not be located in the space with precision.
In 1924, Louis Victor de Broglie (1892−1987) asserts that any matter has an associated wave. The space of ​​the particle depends on the temperature, that is the famous wavelength of de Broglie.
Then come the fiber spaces and the concept of neighborhood, of projection and connection.
This is a separate space (fiber) supported on another space (base) where each point of the base accepts a neighbor, all connected by a series of "cards" which commute. The representation is not at all intuitive. One type of fiber space is given by the Möbius strip (see picture).
Since 2500 years, we have expanded the concept of space to Euclidean geometry, non-Euclidean manifolds, non commutative geometry pasting to quantum physics then to fiber spaces pasting to quantum physics fields, but scientists have not yet found a unified theory of space and time that works in two worlds, that of the subatomic world and the macroscopic world.
It is quite possible that the notions of space and time do not exist but only appear when our eyes interpret the world around us.
