What is the difference between spacetime and event?

spacetime | event |

In context|physics|lang=en terms the difference between spacetime and event

is that spacetime is (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, eg the 5-dimensional spacetime of kaluza-klein theory or the 11 dimensions of spacetime in m-theory while event is (physics) a point in spacetime having three spatial coordinates and one temporal coordinate.

As nouns the difference between spacetime and event

is that spacetime is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time while event is an occurrence; something that happens.

spacetime

Noun

  • (uncountable, physics) The four-dimensional continuum of the three spatial dimensions plus time.
    • An event is a point in spacetime , specified by the coordinates x,y,z and t.
  • (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.
  • (relativity) 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," etc. as opposed to sense (2) describing the universe's spacetime as a whole: "a Minkowski spacetime," "a 5-dimensional spacetime," etc.
