One-Dimensional Universe

The One-Dimensional Universe is a realm that only has one dimension. This means that the only dimension it contains is length. So, the shape of a one-dimensional universe is a line. The only entities that can exist in this realm are dots (zero-dimensional entities) or lines smaller than the realm itself. These entities can only move in the straight line on the realm, in two possible directions. If an entity exists between two other entities in this realm, it is impossible escape from being in between those two entities. One-dimensional universes are contained within two-dimensional universes.
