Yah...but actually, I was making a reference to Heinlein's "The Number of the Beast." Wherein they reveal that the universe has three space axes and three time axes, but we just don't perceive the other two. Travel along them enables one to travel about a multiverse of possibility.
Only problem is, the six-dimensional space is curved, and in such a way that they eventually are unable to return to their home universe. Which is okay, 'cause their house got blown up by a nuclear device anyway.
