## Gymnastic High Bar

Ideas about how a world with more than three spatial dimensions would work - what laws of physics would be needed, how things would be built, how people would do things and so on.

### Gymnastic High Bar

In 4D the high bar of gymnastics could be two dimensional. In general, in N dimensions the high bar can be N-2 dimensional. Only two barless dimensions are needed to grab a bar then circle around it.

Perhaps tetraspace inhabitants would have 2 different high bars, one that resembles a prismic cylinder and one that resembles a spherinder.

You can take the cartesian product of a 2d disk, and any arbitrary 2d shape, like a pentagon or a "H" shaped cut-out, to which you can attach a cubinder on all 4 corners, and thus you have a 4d wheel axle.

My best guess is that gym bars would still be 1D. That both gives the athelete the maximum freedom and also minimizes cost. A potent combination.

So why did I bring it up? Because the idea of a 2D gym bar is mind boggling. I hope.

Suppose you have a 1D gym bar in 5D. Then you could have two gymnasts doing giant circles on that bar in two planes whose intersection is a point. No danger of collision.

### Re: Gymnastic High Bar

The gym bar would be something that separates height of a wall, that is N-2 dimensions. That's what is necessary to divide the space of the track.
