Is it moving because you can’t really show us more than three dimensions without using time?
When I look at it, my mind automatically goes “uuhhhh… shapes don’t move (by themselves anyways)”
My main question - are you yourself capable of mentally visualizing it in four dimensional space? Do you know if anyone is?
I get that a line is in 1 dimension and has 2 points
A square is in 2 dimensions and has 4 points
A cube is in 3 dimensions and has 8 points
A tesseract is in 4 dimensions and so it has 16 points
As I understand, it’s supposed to be pretty much two cubes connected / shifted by a fourth dimension. When I looked up pictures, it pretty much shows a cube within a cube - but they should be the same size… which I guess explains why your moving picture has them looking like they are growing and shrinking. Optical illusion because we are stuck in 3-d?[/quote]
I answered most of this in my response to Pat, but it is actually rotating in my avi, but not in the same way that a 3 dimensional object does. The optics of the human eye is not capable of deciphering the 4th dimension, so we have to rely on optical illusion (similar to drawing a cube on a piece of paper), but our brains are capable of understanding and conceptualizing other dimensions, it just takes a lot of advanced study in order to do so.

Ok then, let me ask this - the two cubes only appear to be changing size because they are moving closer and farther from the observer?

A tesseract is actually 8 distinct cubes arranged in a way that is impossible for the human eye to “see,” which is why we must rely on optical illusions like in my avatar to show them moving. The apparent changes in the size of the sides of the tesseract in my avi is due to the rotation, which is a close approximation of what a rotating tesseract looks like but is not perfect.
