The Dimensions

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.

What is your favorite dimension?

The Dimensions

Very important:

For any further analogies, or discussions of higher or lower dimensions,
please first read my topic on page 8; some if it is balony but most of it is good, so please do that before relations of 3D to 4D or vice versa.

Now that you mention the idea of infinite dimensions:

Since energy dissipates more quickly, the higher the dimension, energy should dissipate infinitely quickly if there were an infinite number of dimensions. That is, to give some examples, the gravitational field at a finite distance from a mass would be 0, and there would be total darkness one meter from a light source.

Would this mean that, ironically, the only possible object in infinite-dimensional space would be a point (a 0-dimensional object)?!

By 1/2, do you mean fractal dimensions, or a universe that's half as big in one direction?

Oh, and don't forget -1 dimensions

Jinydu, you are assuming that there is finite space in a universe with infinite dimensions. That may not be the case. I suppose the closest visualization for infinity besides x/0 would be the transition to a higher dimension, now the infinity of that and that and that and so on would be something perhaps a point but maybe different. The time would be s, but m to the infinite, would make it only distance since x/0/s would be the same as x/0 so that would mean that there is no infinite dimension.

I put those two as a joke, infinity and 1/2, that's why there's a ?>?>?>??!?! after 1/2
