spacetime
/ˈspeɪs.taɪm/
Definition
The four-dimensional continuum that combines the three dimensions of space with the one dimension of time into a single framework used to describe physical reality.
Etymology
The word is a 20th-century compound formed by combining 'space' (from Latin 'spatium') and 'time' (from Old English 'tīma'). It emerged in modern physics as a direct translation of Hermann Minkowski's German term 'Raumzeit' to describe Einstein's theory of relativity.
