We get it. You think of dimensions as states of consciousness. That's cool. Just don't stick it where it isn't relevant.

the 1st dimension only has length. The 2nd only has length and width. The 3rd dimension, in which we experience everything has length, width, and depth. We are capable of seeing and conceiving of the 1st and second dimensions already, through terms such as "A line" (Or more formally, a vector), and "A plane". Mathematically the 4th dimension occupies a space within which a 4th identifier is required in order to denote the location or shape of the simplest object. If there is a 4th dimension we have no way of interacting with it, (Scientists no longer believe time is the 4th dimension, so the idea of 4d being 3d+ time travel is silly) and therefore there's no practical benefit to making **** up about beings or objects within it because they cannot affect us and we cannot affect them. To such an immutable degree that we cannot even OBSERVE them, since that would require things in our universe to have come from the 4th dimension so that we could see how the 4th dimension had affected them. Put into perspective, in 3 dimensions a photon being picked up and observed by the eye denotes the presence of light. the qualities of that photo or stream of photons concludes our experience of that light and allows us to determine qualities of an object, IE, is it red, is it blue. No such relationship exists (nor can it exist) between ourselves and the fourth dimension. We can, geometrically, envision the concept of a 4th plane of existence, however a plane of existence is defined not as a place or space, it is defined as another direction in which something is able to travel, one fundamentally separate from the preceding directions. As such, we return to the idea of 1d 2d and 3d. A single dimension is a line. However since this "dimension" has no width, or depth, only length, its more accurate to conceive of its as a vector. There is only one, predescribed, vector of motion. When we add a second vector along which the point of location can be defined, we obtain a 2d shape - the boundary within which location can be defined, has changed to have both length and width. The length remains from the first dimension, and the new dimension, width, CANNOT affect the length. One can only increase the length of the vector by increasing the length of the vector. Increasing the width (Of the "Plane" that defines 2d) will have no effect on anything but the width. When we move into 3d, we add a third vector, that being "depth". We can now move in 3 directions, independently and with not one of those vectors of motion affecting any element of the other two. One can increase the length, depth, and width of the shape being described one at a time without the others being affected at all. When we add a 4th dimension to our concept of a shape, we describe a way in which something can move, physically, in a direction (along a vector), without affecting the other 3 vectors. The challenge of describing a 4th dimension is in determining how one can change a point of location in space, without changing length, width, or depth. Now, a dimension is described as such, but it is also described (And indeed defined) as a quality of the space within which an object resides. This means shapes and objects are not defined as 3 dimensional, but rather the space within which an object IS is defined with however many dimensions. If there were a 4th dimension that occupied any tangible part of our lives, then WE WOULD EXIST WITHIN 4 DIMENSIONS, because the dimension is not a quality of the OBJECT, but the SPACE. We can observe this for ourselves in computer games, where we can already define code that can give a virtual space either 2d or 3d qualities, or even 1d, but I'm not aware of any games with only 1 possible vector of motion. (Arguably Pong is, but only for the object the player controls. The pong dot with which one scores is definitely moving within a 2d virtual space. The bat itself however only has 1 dimension of movement, the game simply uses a 2d visual representation of a boundary within the game code moving in 1 dimensional virtual space so that we can more easily see where it is.) As an aside: Interesting fact - Any "2D" game is in fact not 2D itself, but rather it is many 2d planes superimposed on top of each other in order to allow independent movement of objects on different planes.

This thread will remain closed until you can act like adults.
