In the meantime, check out this whole tutorial about Tetraspace. Four dimensions!!! Eric thinks Heaven may end up being four dimensional, and if we look at Plato-esque ideas in the Bible (down where it says "Now we see but a poor reflection as in a mirror; then we shall see face to face"), we see that heaven WILL be a whole lot MORE than what we experience now. And a 3D "realmspace" could hang on a 4D universe wall, and swing back and forth, scraping the wall as it goes. So 3D is just as flat to 4D'ers as 2D (mirror or painting) is to us 3d'ers.
A three-legged stool would ALWAYS fall over in a four dimensional universe.
When i was eight or nine, i was given a 110 camera. I burned up a couple rolls, focusing on things like a window. Or a tree. Look, it's grass! A cow! We had cows.
You MIGHT be able to balance a stool in 4D on its three legged “edge”...
-- Eric (Email) - 30 July '04 - 11:34Sure, you could balance a 3 legged stool if the parts that contacted the ground were wide enough, same as you could balance a two (or one) legged stool here if the legs were big and chunky. Maybe a tripod would be a better object to illustrate than a stool.
And just like adding a wheel to a normal 3D car won’t add significantly to stability, and 3 wheeled cars are hard to make safe, so a 4 wheeled car in a 4D universe would benefit enormously by a fifth wheel.
Finally… that alkaline site taught me that tire tracks are 3D, extended rectangular box shapes. WEIRD.
