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

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 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.

In relativity|lang=en terms the difference between spacetime and spacetime

is that spacetime is (relativity) a specific region of the universe with mathematically different properties than the surrounding spacetime synonymous with "metric" within the context of general relativity while spacetime is (relativity) a specific region of the universe with mathematically different properties than the surrounding spacetime synonymous with "metric" within the context of general relativity.

As nouns the difference between spacetime and spacetime

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

As nouns the difference between world and spacetime

is that world is human collective existence; existence in general while spacetime is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time.

As a verb world

is to consider or cause to be considered from a global perspective; to consider as a global whole, rather than making or focussing on national or other distinctions; compare globalise.

As nouns the difference between ether and spacetime

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

As nouns the difference between spacetime and eternity

is that spacetime is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time while eternity is (uncountable) existence without end, infinite time.

In physics terms the difference between spacetime and matter

is that spacetime is 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 while matter is matter made up of normal particles, not antiparticles. (Non-antimatter matter).

In physics terms the difference between spacetime and supercurvature

is that spacetime is 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 while supercurvature is the curvature of spacetime in higher dimensions (in supersymmetry.

As nouns the difference between spacetime and supercurvature

As nouns the difference between spacetime and quantion

is that spacetime is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time while quantion is (physics|mathematics) a form of quaternion used to explain the electroweak theory on curved spacetime.

In physics terms the difference between spacetime and achronal

is that spacetime is 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 while achronal is describing a set of points in a spacetime, no two of which have timelike separation.

As a noun spacetime
