(nothing). Don't be concerned about trying to picture a one dimension finite line. We can picture a two dimension universe somewhat, but going back to a one dimension universe and trying to picture it is much more difficult. A transparent two dimension square with a two dimension light source (a line the same length as the side of the square) shining fully head on (the lens as big as the object in front of it) would yield a one dimension shadow. (a line) A transparent three dimension cube with a three dimension light source (a light source in the shape of the sides of a square with the inside blacked out so that you only saw the sides of the square itself lit up) shining fully head on (the lens as big as the object in front of it [this is necessary because if the light source is bigger or smaller than the cube, the resulting shadow will be a square inside a square]) would yield a two dimension shadow. (a square) A transparent four dimension tesseract with a four dimension light source shining fully head on (the lens as big as the object in front of it [again, you will please figure out further explanation for yourself]) would yield a three dimension shadow. (a cube) A three dimension creature can see all four sides of the two dimension square. (he sees one side of his cube) A four dimension creature can see all six sides of the three dimension cube. (he sees one side of his tesseract) A two dimension creature can see two sides of his four sided square at once by standing at one corner. A three dimension creature can see three of his six sided cube at once by standing at one corner. A four dimension creature can see four of his eight sided tesseract at once by standing at one corner. (Meaning he can see all six sides of the cube at once, inferring some type of what to us would be surround vision.) ...... continued on next page Previous Page <-> Next Page |
