Spacetime may be modelled mathematically as the four-dimensional real vector space ℝ3+1\mathbb{R}^{3+1} , which is canonically identified with ℝ4\mathbb{R}^{4}. While no distinction exists at the level of pure set theory, it is customary, both for physical interpretation and analytical convenience, to regard one dimension as temporal and the remaining three as spatial. Accordingly, Cartesian coordinates
