Dimensions 0 thru 6 together (HOLY CRAP)

Dimensions 0 to 6 displayed simultaneously.

Spatial dimensions are the dimensions used in many fields of mathematics.


Dimension 0—a mathematical pointEdit

Dimension 0 is literally a point in space. Points can be described by coordinates, (x, y), and graphed on a coordinate plane. Since a 0-dimensional object has neither length, width, nor depth, it is immeasurable.

Vertices*: 20 = 1
Total Possible Lines†: (1 * 0)/2 = 0

Dimension 1—a lineEdit

Dimension 1 is any two 0-dimensional points connected with a line, ray, or segment. A 1-dimensional object can only be measured in length. If you were a 0-dimensional object looking at a 1-dimensional line, you would see a point that appears and disappears where the line is. In other words, the line would appear in cross-sections of points. 1-dimensional lines can stretch for an eternity.

Vertices: 21 = 2
Total Possible Lines: (2 * 1)/2 = 1

Dimension 2—a flat planeEdit

Dimension 2 is at least two 1-dimensional lines that either connect or intersect to form a plane. A plane has width and length. To a 1-dimensional line, a plane appears as both lines and points.

Vertices: 22 = 4
Total Possible Lines: (4 * 3)/2 = 6

Dimension 3—3-dimensional spaceEdit

Dimension 3 is at least two planes that either connect or intersect to form 3-dimensional space. 3-dimensional space has length, width, and height. A 2-dimensional plane would see space as a cross section of definite 2-dimensional shapes.

Vertices: 23 = 8
Total Possible Lines: (8 * 7)/2 = 28

Dimension 4—4-dimensional spaceEdit

4-dimensional space is made when at least two 3-dimensional spaces converge and/or intersect. Imagining this dimension and onwards is notoriously difficult for our minds to conjure, with each new dimension becoming increasingly complex and consequentially harder to conjure.

Vertices: 24 = 16
Total Possible Lines: (16 * 15)/2 = 120

Dimensions 5 and Above—x-dimensional spaceEdit

Each dimension after dimension 4 is a more complex version of space than the previous. For example, 5-dimensional space is made by intersecting multiple 4-dimensional spaces, and 6-dimensional space is made by intersecting multiple 5-dimensional spaces, and so on and so forth.

For dimension 5,
Vertices: 25 = 32
Total Possible Lines: (32 * 31)/2 = 496

For dimension 6,
Vertices: 26 = 64
Total Possible Lines: (64 * 63)/2 = 2,016

For dimension 7,
Vertices: 27 = 128
Total Possible Lines: (128 * 127)/2 = 8,128

For dimension 8,
Vertices: 28 = 256
Total Possible Lines: (256 * 255)/2 = 32,640

For dimension 9,
Vertices: 29 = 512
Total Possible Lines: (512 * 511)/2 = 130,816
