the four-dimensional coordinate system (3 dimensions of space and 1 of time) in which physical events are located
(countable, uncountable)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.
a Minkowski spacetime
a 5-dimensional spacetime
(countable, uncountable)A specific region of the universe with mathematically different properties than the surrounding spacetime. Synonymous with "metric" within the context of general relativity.
a Schwarzschild spacetime
a Reissner-Nordström spacetime
