four-dimensional

It's not particularly playable, but it is true four-dimensional space with four-dimensional spaceships zipping around.

One way to do this calculation is to use a discrete four-dimensional lattice to model a section of space-time.

Human brains simply are not designed to understand, at a deep intuitive level, things like the geometry of four-dimensional pseudo-Riemannian manifolds.

No thank you; cyclists treat stop signs as four-dimensional yields for some damn good reasons.

With math, we can calculate what it would be like to navigate in four-dimensional space.

The OP could have simply said that, in relativity, there's no force called gravity, instead planets orbit their parent bodies because of curved four-dimensional spacetime.

I guess we just use four-dimensional spacetime only when it's necessary and treat it as good old time-that-marches-on when we don't have to.

Therefore, she will have a four-dimensional color space.

It is thought that the four-dimensional space, which you may have just been thinking about, exists due to distant entangled quarks and may be the thing we call space-time.

I too believe that the line between life and non-life is fuzzier than it looks, and that our four-dimensional information patterns are difficult to disentangle from the surrounding ecosystem, and the seemingly unalive habitat in which we dwell.

Maxwell's equations aside, this relation is four-dimensional, because two of its dimensions (e and m) are dependent on the other four (x, y, z, and t), making the relation a function: x×y×z×t→e×m.

Also, the rendering of the wormhole as a four-dimensional "hole" embedded in three-dimensional space was absolutely gorgeous.

One of his results is a proof of the four-dimensional Poincaré Conjecture".

My favorite phrase in this article was "four-dimensional enraged-leprechaun hypercube visualization".

Going a little further with the thought (and I am definitely not a physicist), what if that electron "loop" (or even the "single electron") is itself moving within the four-dimensional space.
