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.
