THE 4TH DIMENSION

the forth dimension is the theoretical dimension beyond our third dimension*, in theory it should be able to be represented by a line in a direction that causes a new vector to form

while that sounds easy we can't conceptualize it, and even if we could we can't depict it, as while one could use 2 dimensional lines to make a cube, a 2 dimensional being could not understand it

if you are a higher dimensional being and reading this, why?
