"No," declared the Engineer, "because they will merge their space-time continuum with the continuum of our universe as soon as the two come together. They will immediately become a part of our universe.”
"You told them how to create a hypersphere?" asked Herb.
"I did," said the Engineer. "And it will save the people of that other universe. They had tried many things, had worked out theories and new branches of mathematics in their efforts to escape. They discovered many things that we do not know, but they never thought of budding out from their universe. They apparently are a mechanistic people, a people very much like we Engineers. They seem to have lost that vital spark of imagination with which your people are so well supplied.”
"My Lord," said Gary, "think of it! Imagination saving the people of another universe. The imagination of a little third-rate race that hasn't even started really using its imagination yet.”
"You are right," declared the Engineer, "and in the aeons to come that imagination will make your race the masters of the entire universe.”
"Prophesy," said Gary.
"I know," said the Engineer.
"There's just one thing," said Herb. "How is that other universe going to be destroyed?”
"We are going to destroy it," said the Engineer, "in exactly the same way we destroyed the Hellhounds.”
