  Four-dimensional space-time "(called" Minkowski space "), Einstein in his general and special relativity mentioned, mainly expressed as "the universe is composed of three dimensions of space and one dimension of time 'four-dimensional space-time'", referring to the "fourth dimension" and other three-dimensional properties are very different. The "fourth dimension" in the concept of "four-dimensional space" refers to the same spatial dimension as other three-dimensional properties.
