2.  Space is the boundless three-dimensional extent in which objects and events have relative position and direction.  Physical space is often conceived in three linear dimensions  Four dimensional Universe- Space time

4.  Events become meaningful when space is associated with time  Lets have an example

5.  Leibniz : Space is no more than the collection of spatial relations between objects in the world: "space is that which results from places taken together". Unoccupied regions are those that could have objects in them, and thus spatial relations with other places.  space was an idealised abstraction from the relations between individual entities or their possible locations and therefore could not be continuous but must be discrete.

7.  Isaac Newton : Space is independent of matter.

8. “ All are Euclidean …”

11.  Carl Friedrich Gauss: a German mathematician, was the first to consider an empirical investigation of the geometrical structure of space.  Henri Poincaré : Coined the concept of ”sphere-world”.

13.  Albert Einstein : 1905, published a paper on a special theory of relativity, which led to the concept that space and time may be combined into a single construct known as spacetime.
