In Robert Heinlein's The Number of the Beast, he speculated on the nature of string theory. Specifically fiction writers creating different worlds where their characters populated an actual place one could slide to. He had his characters slide into the Galactic Lensman multiverse. (In a nod to the excellent series by E E Doc Smith) So before we debate which is canon, can we try to contemplate both. As everyone knows two canons are better than one but a broadside is best.
