Spacetime vs Quantion - What's the difference?
spacetime | quantion |
(uncountable, physics) The four-dimensional continuum of the three spatial dimensions plus time.
(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, e.g. the 5-dimensional spacetime of Kaluza-Klein theory or the 11 dimensions of spacetime in M-theory.
(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 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

- An event is a point in spacetime , specified by the coordinates x,y,z and t.
- "a Schwarzschild spacetime," "a Reissner-Nordström spacetime," etc. as opposed to sense (2) describing the universe's spacetime as a whole: "a Minkowski spacetime," "a 5-dimensional spacetime," etc.
