Digitally-generated illustration of a clockface converted into an infinite spiral suggesting the relativistic nature of spacetime. In physics,spacetime is any mathematical model that combines space and time into a single interwoven continuum. The spacetime of our universe is usually interpreted from a Euclidean space perspective,which regards space as consisting of three dimensions,and time as consisting of one dimension,the fourth dimension. By combining space and time into a single manifold called Minkowski space. The terms time warp,space warp,and timespace warp are commonly used in science fiction. Spacetime warps sometimes refer to Einsteins theory that time and space form a continuum that bends,folds,or warps from the observer's point of view,relative to such factors as movement or gravitation |
