In City on the edge of forever, Spock says about the Guardian of Forever
"A time portal Captain, a gateway to other times and dimensions if I am correct" and the guardian replies "As correct as possible for you..."
Now the Guardian could be indicating that he's only correct about the first aspect of his reply but maybe not.
Has anyone within the books ever used the angle that the Guardian can be used for transport to other dimensions rather than to just to travel in time?
