The fourth dimension as time
Main article: Spacetime
Usually, when a reference is made to four-dimensional coordinates, it is the temporal interpretation which is meant. In this case, the four coordinates are understood to represent 3 dimensions of space plus 1 dimension of time. Such a space is called a Poincaré space, Minkowski space, or "(3 + 1)-space",[1] and is the space used in Einstein's theories of special relativity and general relativity.
