Space

Space is treated differently in different aspects. In physics; the space is usually understood as “the boundless three-dimensional extent of universe, where all material objects and organisms (including rational beings like ourselves) exist and in which objects and events occur”. All material objects in the universe have their relative as well as absolute positions and motions in the space. Space, itself, has no material existence. It cannot provide sense-experience to rational beings. In physical descriptions, only an entity that has physical existence can be sensed or extend or shrink. As no entity with physical existence is mentioned in the definition of space, space is an imaginary (functional) entity. A functional entity has no objective reality and can fulfill only the functions assigned to it by the proposer. It exists only in the mind of proposer and in mathematical analyses. Space is a functional entity that serves the purpose of locating various material bodies in it and where rational beings relate themselves with each other. The extent, outside material bodies, becomes the space. In contemporary physics, the imaginary space is able to dilate or contract as required even without objective reality. Currently, empty space is endowed with many of physical properties that a material object may have while it is also considered as absolute vacuum. All spatial concepts are related to contact-experiences of (matter) bodies. This has made it necessary to envisage an entity independent of bodies and yet embodying their locations. This entity, outside material bodies yet enclosing them, came to be understood as space. When a rational mind envisages a real object, it logically pre-supposes a place for its existence. This is understood not by sensing such a place but by the necessity of a place for the existence for any real body to exist. As a result, the notion of space is somewhat incoherent because it professes to be a container that is logically prior to its contents. Space turns out, in practice, to be merely an indefinitely extensible collection of its contents. Everything that occupies space falls within this wider spatial context. Space denotes a property by virtue of which different bodies occupy different positions in the universe. The possibility of arranging an unlimited number of matter-bodies next to one another denotes that the space is infinite in its extent. However far one can go, matter-bodies are there and beyond. If the space, outside the most basic 3D matter-particles, is filled entirely by a real universal medium, the medium and the space become synonymous. Space is no more an imaginary void, but a real medium, which contains all three-dimensional bodies in nature. Now, since the universal medium has a structure and constituents, it is able to deform and undergo all actions normally the imaginary space is assumed to perform. The universal medium can also substitute for various types of fields, used in present theories. Since the universal medium encloses all three-dimensional bodies, it acts as a direct link between any two such bodies and the assumption of ‘action at a distance through empty space’ is not required any more. The concept, proposed in the book, ‘MATTER (re-examined)’, considers space as an imaginary container, envisaged by rational beings as and when they think about three-dimensional material objects. It extends infinitely in all directions from the observer. In order to make space a real entity, it has to have substance that provides it with objective reality and positive existence. In material world, existence of matter is nearest to absolute truth. Therefore, in order to be real, space has to be made up of matter. When space is real, it can behave like any other real entity.
