spacetime | supercurvature |

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

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 supercurvature is (physics) the curvature of spacetime in higher dimensions (in supersymmetry).

## As nouns the difference between spacetime and supercurvature
