Today's physics understands space and time as being coupled in "space-time"; a fundamental arena in which universe takes place. Einstein himself has never considered time as being part of space; he was talking about a "four-dimensional continuum" in which physical events occur. In his Special Theory of Relativity Einstein used Minkowski's 4-dimensional space that has four coordinates: X1, X2, X3, X4 where X4 = ict. X4 is not a "temporal coordinate", X4 is not the time t that is measured with clocks. In the formula X4 = ict, time t is only a component. Out of this mathematical formalism one can conclude that in the Special Theory of Relativity time t is not part of space. Minkowski space is not 3D+T, it is 4D (1).
