Anyway, ok. Think about it like this. Ever have an Etch-a-Sketch as a kid? The thing with the little knobs that you turn to draw up and down or left and right, and make pictures out of?
Ok, well, left and right would be the X axis. Up and down is the Y axis. Now imagine the addition of another range of motion, it is one that actually A) comes out of the screen of the Etch-a-Sketch, toward your face, and B) goes down through the back of the screen, and through the table that the Etch-A-Sketch is sitting on, and continues down to, and through, the floor.
That is the Z axis. A.k.a. Depth.
Sweetshoes:
I think existence could be interpreted by Dimension 0. It is a point. Whether that point is consciousness in its most supressed state, or an inanimate object with no mass. (An electron or any other subatomic particle, for instance) That would be a representation of 0 Dimensions. Stretching that particle left and right would be the X axis. 1 Dimension. Stretching it along the Y axis would add another dimension. The Z axis would make 3. It is Depth.
As far as all units of measurement that we are familiar with, those are most fundamental 3. Together they make up length, width and height, and they are all interchangeable, depending on your point of reference.
Everything after that is up for speculation, at this point.
