Space
in geometry, the room in which an object, actual or imaginary, exists. All material objects possess length, breadth, and thickness; in other words, they exist in space of three dimensions.
Plane surfaces have only two dimensions -length and breadth, and straight lines but one dimension-length. Hence we have notions of space of one dimension and of two dimensions, as distinguished from the three-dimensional space in which we live. The question has arisen, and has been warmly discussed, as to whether space of four, and perhaps of higher dimensions exists. Zöllner believes that it does, and that some persons have some of the power of beings living in space of four dimensions, and thus accounts for many of the phenomena of Spiritualism. For example, SPAIN while a being living in space of two dimensions could only get in or out of a square by passing through one of its sides, a human being could enter the square from above; so, he argues, a person having the properties of a four-dimensional being could enter or leave a closed box or room on its fourth-dimensional side. In metaphysics, a conjugate of material existence. Empirical philosophers maintain that notions of space are derived from our knowledge of existence; transcendentalists that these notions are innate. In music, one of the four intervals between the five lines of a staff. They take their names from the notes which occupy them; thus, the spaces of the treble staff, counting upward, are F, A, C, and E, and of the bass, A, C, E, and G.
In physics, the room in which the Cosmos or universe exists. In printing, the interval between words in printed matter; also pieces of type-metal shorter than type, used to produce such spaces or to separate letters in words, of varying thickness, so as to justify the line.
