"Formless," said Caroline. "Of course, it would be formless. It wouldn't be light, or heat, or matter, or motion, or any other form of energy such as we know. But it could be anything. It would be waiting to become something.
It could crystallize into anything.”
"Good Lord," said Gary, "how could you handle stuff like that? Your hyperspheres wouldn't handle it. It could mold space itself. It could annihilate time.”
Caroline looked at him soberly.
"If I could create a fifth-dimensional trap," she said, "if I could trap it in the framework of the medium from which it came. Don't you see that such a framework would attract it, would gather it in and hold it. Like a battery holds energy. Like water seeking its own level and coming to rest.”
"Sure," agreed Gary, "if you could create a fifth-dimensional trap. But you can't. It's eternity. The dimension of eternity. You can't go fooling around with eternity.”
"Yes, she can," said the old man.
The two of them stared at him, not believing.
"Listen closely," said the oldster. "By rotating a circle through three dimensions you create a sphere. Rotate the sphere through four dimensions and you have a hypersphere. You already have created this. You have bent time and space around a mass to create a hypersphere, a miniature universe.
Now all you have to do is rotate the hypersphere through five-dimensional space.”
