Any practical uses for 4+ dimensional geometry?

[sqishy]

It wouldn't be thought that imaginary numbers, those that derive from some sort of root of a negative number, not possible in a "real" sense, would have any practical application in a real sense. But they do: imaginary numbers are used in algorithms and calculations to direct aircraft in air traffic control, ships in sea transport systems, and satellites/spacecraft in orbit around,and beyond, earth.

So my question is, does anybody know any possible or actual practical real-world application of 4+ dimensional geometry (tesseracts, 5-cells, penteracts etc.) and algebra? Or do you have any creative idea, no matter how imaginative, in what they could be used for ?

I dunno, art maybe?

I meant more in a sciency way.
But in terms of art it's already been done and is an amazing idea :D

If we'd ever begin traveling near the speed of light(Which would only happen if we'd find either a very strong amount of fuel and a lot of it, or something with an infinite amount of energy, which so far, has not been discovered), I can assume some of those calculations would be needed. I may be incorrect, seeing as math is not my strong suit, but it's a fair assumption.

Well here's an artwork featuring the net of a tesseract:

I usually ask myself that, then I ask my dad (he is a petroleum engineer) and he will give me a lot of examples for practical uses of geometry and algebra, you will use it (or it will help you understand something) you just aren't aware of it because math is inevitably part of our lives.

4 dimensional geometry is used quite a bit in cosmology, and any research involving possible theories for our universe. Physics embraces 4+ dimensional planes all of the time. I'm not sure if there uses can be considered "practical" in an everyday sense, but they're very helpful when trying to define the smallest parts of our universe.
