Definition of Spacetime

1. Noun. (uncountable physics) The four-dimensional continuum of the three spatial dimensions plus time. ¹

2. Noun. (physics) An ''n''-dimensional continuum consisting of dimensions of both space & time. Normally spacetime is considered as having 4 dimensions (''x'', ''y'', ''z'', ''t''), but higher-dimensional spacetimes are often encountered in theoretical physics, e.g. the 5-dimensional spacetime of Kaluza-Klein theory or the 11 dimensions of spacetime in M-theory. ¹

3. Noun. (relativity) A specific region of the universe with mathematically different properties than the surrounding spacetime. Synonymous with "metric" within the context of general relativity. ¹
