A 1-Dimensional Space is a space in which every position can be described using a single number. There may also be some number of time dimensions, such as the typical 1+1 dimensional space comprising matter in a straight line that varies with time. A Hypersphere in the first dimensional is called a "0-sphere" because the surface is 0-Dimensional, the length of such a sphere would be measured as , with "r" as the radius.
A verse that is one dimensional is called a lineverse.
