No a ray which is infinite in one direction
is not more infinite than a line which is infinite in both directions
is not more infinite than a plane which is infinite in any direction
is not more infinite than 3 space which is infinite in all directions.

exp:R -> (0,oo), x -> e^x is a continuous bijection
between a line and a open ray.
