Why persons believe to the additional space dimensions? They say that two dimensional mortal was not can understand three space dimensions. Who understand two dimensional mortal, to the object or macrocosm? Even though mortal would be how thin ever, so in any case it is three-dimensional. If you take away as the thickness's completely, no left behind remains anything. Therefore is futile to justify on the two dimensional matters additional space dimensions. Not two dimensional matters exist. We don't needs additional space dimensions to explain how macrocosm seriously functioned.
