It's a nice phrase, but it's only meaningful if we live in a Euclidean (flat) universe. This is unlikely.
It is possible that the curvature of the universe imposes a diameter - consider a sphere where the inhabitants can seemingly wander in a straight line forever, yet there is a diameter. It is also possible that the curvature is the other way from flat, and imposing no diameter. For this, consider not a sphere but a monkey saddle.
