spacetime

باللغة العربية: زَمَكَان

1. The four-dimensional continuum of the three spatial dimensions plus time. (uncountable) · An event is a point in spacetime, specified by the coordinates x, y, z, and t.
2. 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. (countable, uncountable) · a Minkowski spacetime· a 5-dimensional spacetime
3. A specific region of the universe with mathematically different properties than the surrounding spacetime. Synonymous with "metric" within the context of general relativity. (countable, uncountable) · a Schwarzschild spacetime· a Reissner-Nordström spacetime
