## In physics|lang=en terms the difference between spacetime and worldsheet

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

**worldsheet** is (physics) a two-dimensional manifold which describes the embedding of a string in spacetime, a direct generalization of the worldline of a particle in special and general relativity.

## As nouns the difference between **spacetime** and **worldsheet**

is that

**spacetime** is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time while

**worldsheet** is (physics) a two-dimensional manifold which describes the embedding of a string in spacetime, a direct generalization of the worldline of a particle in special and general relativity.
