5DSPACE-TIME
Updated 31 days ago
Our primary model of the dimensions of space is geometry, which is based on the four concepts of the point, the line, the plane, and three-dimensional space. Our most common model of the dimension of time represents time in the form of a line that flows in one direction only, a unidirectional ray. The words point, ray, line, plane, and space reflect the assumption in geometry that space is infinite.
