A. EINSTEIN wrote about two different concepts of space:
"a) space as a positional quality of the world of material objects
"b) space as container of all material objects.
"In case a), space without a material object is inconceivable. In case b), a material object can only be conceived as existing in space; space then appears as a reality which in a certain sense is superior to the material world".
EINSTEIN's synthetic opinion however is: "Both space concepts are free creations of the human imagination, means devised for easier comprehension of our sense experience".
He adds: "The victory over the concept of absolute space or over that of the inertial system became possible only because the concept of the material object was gradually replaced as the fundamental concept of physics by that of the field… that which constitutes the spatial character of reality is then simply the four-dimensionality of the field. There is then no "empty" space, that is, there is no space without field" (in M. JAMMER, 1957, p.XIV – XVI).
H. MINKOWSKI already in 1908 wrote: "Space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality" (in his lecture "Space and Time" – reproduced in "The Principle of Relativity" – Methuen, 1923, p.75, reedited by Dover).
And, as "there is no space without field ", it becomes also obvious that energy and matter, by themselves also fade away as isolated concepts.
P. MANZELLI offers a different, but convergent, view of space: "… the space concept is an essential consequence of the information/matter interactions, that depend on the 'auto-organization' of the dynamical processes in the physico-chemical transformations" (1993, p.333).
Space, like time, matter and energy seems to be an aspect of a global frame for reality (EINSTEIN's field 7) that our mind fragments in its utmost effort to understand "the world there outside".
Via the organization of the brain network, as an information processor, these different notions could finally be parts of our constructed conceptual autopoietic frame of reference.
