The space-time continuum (it) : continuum time - time and space composed of four-dimensional space-time structure, the first proposed, in the four straight. The space-time continuum, "distance" s definition for s ^ 2 = x ^ 2 + 2 + z y ^ ^ 2 - (ct) ^ 2, including the x, y, z coordinate for space for time, t, c for vacuum speed coordinates. This can see it with four-dimensional space is the largest European different, because the first four coordinates in four-dimensional than the statute's position. The four-dimensional space-time continuum bending can be regarded as the former promotion, as bending N ou N dimension space is the promotion.
