spacetime

World vs Spacetime - What's the difference?

world | spacetime |


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.

Ether vs Spacetime - What's the difference?

ether | spacetime |


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.

Spacetime vs Eternity - What's the difference?

spacetime | eternity |


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.

Spacetime vs Matter - What's the difference?

spacetime | matter |


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).

As nouns the difference between spacetime and matter

is that spacetime is the four-dimensional continuum of the three spatial dimensions plus time while matter is substance, material.

As a verb matter is

to be important.

spacetime | timespace |

Timespace is likely misspelled.


Timespace has no English definition.

As a noun spacetime

is the four-dimensional continuum of the three spatial dimensions plus time.

Spacetime vs Supercurvature - What's the difference?

spacetime | supercurvature |


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

is that spacetime is the four-dimensional continuum of the three spatial dimensions plus time while supercurvature is the curvature of spacetime in higher dimensions (in supersymmetry.

Spacetime vs Quantion - What's the difference?

spacetime | quantion |


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.

Spacetime vs Achronal - What's the difference?

spacetime | achronal |


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

is the four-dimensional continuum of the three spatial dimensions plus time.

As an adjective achronal is

describing a set of points in a spacetime, no two of which have timelike separation.
