#### Continuum vs Spacetime - What's the difference?

continuum | spacetime |

## As nouns the difference between continuum and spacetime

is that continuum is a continuous series or whole, no part of which is noticeably different from its adjacent parts, although the ends or extremes of it are very different from each other while spacetime is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time.

#### Spacetime vs Wormhole - What's the difference?

spacetime | wormhole |

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

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 wormhole is (relativity) a hypothetical shortcut between two points in spacetime, permitting faster-than-light travel and sometimes time travel.

## As nouns the difference between spacetime and wormhole

is that spacetime is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time while wormhole is a hole burrowed by a worm.

#### What is the difference between spacetime and event?

spacetime | event |

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

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 event is (physics) a point in spacetime having three spatial coordinates and one temporal coordinate.

## As nouns the difference between spacetime and event

is that spacetime is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time while event is an occurrence; something that happens.

#### What is the difference between spacetime and singularity?

spacetime | singularity |

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

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 singularity is (physics) a point or region in spacetime in which gravitational forces cause matter to have an infinite density; associated with black holes.

## As nouns the difference between spacetime and singularity

is that spacetime is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time while singularity is the state of being singular, distinct, peculiar, uncommon or unusual.

#### What is the difference between spacetime and time?

spacetime | time |

## As nouns the difference between spacetime and time

is that spacetime is (uncountable|physics) the four-dimensional continuum of the three spatial dimensions plus time while time is (uncountable) the inevitable progression into the future with the passing of present events into the past.

## As a interjection time is

(tennis) reminder by the umpire for the players to continue playing after their pause.

## As a verb time is

to measure seconds, hours etc passed, especially using a clock of some kind.
