SPACETIME

Etymology

Noun

spacetime (countable and uncountable, plural spacetimes)

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

(physics) An n-dimensional continuum consisting of dimensions of both space and 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.

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