Spatial states of existence of matter

Matter provides substance to all real entities. A three-dimensional matter-particle contains matter without voids in it. Whole space, occupied by a 3D matter-particle, is occupied by matter. Real universal medium is also made up of matter. Universal medium fills the entire space outside 3D matter-particles. There are no voids in it either. Hence, entire space outside 3D matter-particles is also filled with matter. In order to satisfy these requirements, matter-density of a 3D matter-particle and the matter-density of universal medium, outside 3D matter-particle, have to be the same. As 3D matter-particles and the surrounding universal medium have the same matter-density, entire space (universal medium along with 3D matter-particles in it) should form a single block of matter of uniform matter-density and of infinite extent and volume. Matter cannot be compressed beyond the matter-density of a 3D matter-particle or that of universal medium. A matter-body of zero volume and infinite mass (singularity) is impossible to achieve. Yet, while the 3D matter-particles and the macro bodies formed by them are tangible and can be sensed, universal medium and its matter-components should remain intangible and hidden from 3D rational beings. This shows that (with respect to rational beings) matter can have different states of existence. In certain states of existence, 3D rational beings can observe matter (in the form of matter-bodies) and in certain states of existence, 3D rational beings can not observe or sense matter (when it is in the form of universal medium). Sensory organs and instruments of 3D rational beings are evolved to sense only 3D matter-bodies. Hence they observe and consider only 3D matter-bodies as real entities. For this a matter-body has to be tangible and observable in 3D spatial system. To be tangible or observable, a 3D matter-body has to have certain measurements in all three spatial dimensions. If dimensions of a 3D matter-body in any or all of three spatial dimensions become too small to be tangible or observable by standards of 3D rational beings, they could no more be considered as (real) 3D entities. However, since these matter-bodies continue to exist in all spatial dimensions, they are real entities. Although these matter-bodies have their existence in all spatial dimensions, rational beings will not be able to observe or sense them, only because their measurements in one or more spatial dimension(s) is/are intangible by 3D standards. If the spatial-dimensional measurement of a matter-body becomes intangible in any one of three spatial dimensions, it may be considered as a two-dimensional matter-body. If the spatial-dimensional measurements of a matter-body become intangible in any two of three spatial dimensions, it may be considered as a single-dimensional matter-body. Therefore, it is possible for matter to remain real and be able to exist in 1D, 2D or 3D states. In its 1D and 2D states, a matter-body is hidden from 3D rational beings. Although these matter-bodies are real, as they are hidden, 3D rational beings may consider them to be functional entities. Only in its 3D state, a matter-body becomes real and observable to 3D rational beings. However, this does not prevent matter in any spatial dimension from being a real entity.
