She looked at him in relief.
"Oh, you know about that," she said. "That makes it easier. Well, then, the next step. You take a cube"—Her face clouded with doubt again, and she explained, "You can't do this with your hands. You've gotta ESP it done, because it's an imaginary cube anyway."
She looked at us questioningly. I nodded for her to continue.
"And you ESP the twisted cube all together the same way you did Klein's Bottle. Now if you do that big enough, all around you, so you're sort of half twisted in the middle, then you can TP yourself anywhere you want to go. And that's all there is to it," she finished hurriedly.
"Where have you gone?" I asked her quietly.
The technique of doing it would take some thinking. I knew enough physics to know that was the way the dimensions were built up. The line, the plane, the cube—Euclidian physics. The Moebius Strip, the Klein Bottle, the unnamed twisted cube—Einsteinian physics. Yes, it was possible.
"Oh, we've gone all over," Star answered vaguely. "The Romans and the Egyptians—places like that."
"You picked up a coin in one of those places?" Jim asked.
