Four-dimensional mathematical system

Usage examples of spacetime.

The near side of the construct formed a tangled, impenetrable fence, twisted exuberantly into arcs and cusps, with shards of galaxy images glittering through the morass of spacetime defects.

The near side of the artifact formed a tangled, impenetrable fence, twisted exuberantly into arcs and cusps, with shards of galaxy images glittering through the morass of spacetime defects.

Hunt found him staring at a display of isochrons and distorted spacetime geodesics, and looking very thoughtful.

The Shrouders were little better, secretive minds cocooned inside shells of restructured spacetime.

French and not Italian, except he thought his last name, Ives, was French, and that was reason enough in a spacescape void of reasons and a spacetime hours remote from actual civilization.

Somehow the weapon created a soliton -- a standing-wave -- in the geodesic structure of spacetime.

For the mathematically inclined reader we note that this extension involves augmenting the familiar Cartesian coordinates of spacetime with new quantum coordinates, say u and v, that are anticommuting: u × v = -v × u.

And it was the duality of universes, each exhibiting a spacetime decomposed into two discrete dimensions, which gave rise to the two-way duality manifested by tweedles and antitweedles: Dums, dees, antidums, and antidees were simply spacelike, timelike, antispacelike, and antitimelike projections of the same fundamental entity existing in the timeless, spaceless domain of tweedlespace.

It surged forward across the rooftops of the city, buildings collapsing in its wake, and struck the heart of the fortress, rending the fabric of spacetime on impact and opening gaps into antiworlds.

Technologies and techniques which may only be deployed by ascended races: means of manipulating spacetime, or of moving faster-than-light.

How the cat in the experiment had vanished and the professors at his university had designed and constructed a spacetime machine using the anomalies in the universal continuum to get around Time's Arrow but then somebody had pushed the wrong button when Neils and himself had gone out down to the Mexican take-aways so that the entire faculty had disappeared into another universe and then the riot squad had arrived and interrogated himself and the rabbit and then made him go after the cat by himself and how had he arrived at Earth to capture the cat and take it back for trial on his planet but he had missed it when the man in the wardrobe wearing the lab coat and Stetson wouldn't talk to him so he accidently vaporized the kitchen and fallen through in the fish tank and gotten electrocuted while standing on the pot plant and decided in the end to open the beer with his hands and not his head.

Then came the second part of the spell, which bilocated the copied spacetime with the one presently proceeding locally.

It was a comfort to imagine the worlds they had left behind on the far side of the spacetime bridge, still attached to the Cauchy as if by some umbilical of stretched spacetime, and living their lives through at the same rate as the Cauchy crew, patiently waiting for the starship to complete its circuit to the future.

Perhaps her Cauchy shipmates were already dead at the hands of the Qax—if that word "already" had any meaning, with spacetime bent over on itself by the wormhole.

If we split spacetime into a Cartesian product of four-dimensional Minkowski spacetime and a six-dimensional compact Kä.
