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

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

**geometrodynamics** is (physics) any of several reformulations of general relativity that attempt to describe spacetime and associated phenomena completely in terms of geometry.

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

is that

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

**geometrodynamics** is (physics) any of several reformulations of general relativity that attempt to describe spacetime and associated phenomena completely in terms of geometry.
