"But you?" asked Gary. "What did you have to do with it?"
"I told the Engineers," she said. "They asked me what we ate and I told them. They must have understood me far better than I thought. I told them the kind of clothes we wore and the kind of furniture we used. But, you see, the only things I knew about were out of date, things the people used a thousand years ago. All except the chicken. You still eat chicken, don't you?"
"And how," grinned Herb.
"Why," said Gary, "this means the Engineers can make anything they want to. They can arrange atoms to make any sort of material. They can transmute matter!"
Kingsley nodded. "That's exactly what it means," he said.
Herb was hurrying for the table.
"If we don't get there, there won't be anything left," Tommy suggested.
The chicken, the mashed potatoes and gravy, the wine, the stuffed olives… all the food was good. It might have come out of the kitchen of the solar system's smartest hotel only a few minutes before. After days of living on coffee and hastily slapped-together sandwiches, they did full justice to it.
Herb regarded with regret the last piece of chicken and shook his head dolefully.
"I just can't do it," he moaned. "I just can't manage any more."
"I never tasted such food in all my life," Kingsley declared.
"They asked me what we ate," Caroline said, "so I thought of all the things I like the best. They didn't leave out a single one."
"But where are the Engineers?" asked Gary. "We haven't seen a thing of them. We have seen plenty of what they have done and can do, but not one has showed himself."
Footsteps rasped across the floor and Gary swung around in his chair. Advancing toward them was something that looked like a man, but not exactly a man. It was the same height, had the same general appearance — two arms, two legs, a man-shaped torso and a head. But there was something definitely wrong with the face; something wrong with the body, too.
"There's the answer to your question," said Tommy.
"There's an Engineer."
Gary scarcely heard him. He was watching the Engineer intently as the creature approached. And he knew why the Engineer was different. Cast in human shape, he was still a far cry from the humans of the solar system, for the Engineer was a metal man! A man fashioned of metallic matter instead of protoplasm.
"A metal man," he said.
"That's right," replied Kingsley, and keen interest rather than wonderment was in his words. "This must be a large planet. The force of gravity must be tremendous. Protoplasm probably would be unable to stand up under its pull. We'd probably just melt down if the Engineers hadn't fixed up this place for us."
"You are right," said the metal man, but his mouth didn't open, his facial expression didn't change. He was speaking to them as the voice had spoken to them back on Pluto and again as they had entered the city. The Engineer stopped beside the table and stood stiffly, his arms folded across his chest.
"Is everything satisfactory?" asked the Engineer.
It was funny, this way he had of talking. No sound, no change of expression, no gesture… just words burning themselves into one's brain, the imprint of thought thrust upon one's consciousness.
"Why, yes," said Gary, "everything is fine,"
"Fine," shouted Herb, waving a drumstick. "Why, everything is perfect."
"We tried so hard to do everything just as you told us," said the Engineer. "We are pleased that everything is all right. We had a hard time understanding one thing. Those paintings on the wall. You said they were things you had and were used to and we wanted so much to make everything as you wanted it. But they were something we had never thought of, something we had never done. We are sorry that we were so stupid. They are fine things. When this trouble is over, we may make more of them. They are so very beautiful. How queer it was we hadn't thought of them."
Gary swung around and stared at the painting opposite the table. Obviously it was a work in oils and seemed a very fine one. It portrayed some fantastic scene, a scene with massive mountains in the background and strange twisted trees and waist-high grass and the glitter of a distant waterfall. A picture, Gary decided, that any art gallery would be proud to hang.
"You mean," be asked, "that these are the first pictures you ever painted?"
"We hadn't even thought of it before," said the Engineer.
They hadn't known of paintings before. No single Engineer had ever thought to capture a scene on canvas. They had never wielded an artist's brush. But here was a painting that was perfect in color and in composition, well balanced, pleasing to the eye!
"One thing about you fellows," said Tommy, "is that you will tackle anything."
"It was so simple," said the Engineer, "that we are ashamed we never thought of it."
"But this trouble," rumbled Kingsley. "This danger to the universe. You told us about it back on Pluto, but you didn't explain. We would like to know."
"That," said the Engineer, "is what I am here to tell you…"
No change in the tone of the thoughts… no slightest trend of emotion. No change of expression on his face.
"We will do whatever we can to help," Kingsley told him.
"We are sure of that," said the Engineer. "We are glad that you are here. We were so satisfied when you said that you would come. We feel you can help us very, very much."
"But the danger," prompted Caroline. "What is the danger?"
"I will begin," said the Engineer, "with information that to us is very elemental, although I do not believe you know it. You had no chance to find it out, being so far from the edge of the universe. But we who have lived here so many years, found the truth long ago.
"This universe is only one of many universes. Only one of billions and billions of universes. We believe there are as many universes as there are galaxies within our own universe."
The Earthlings looked in astonishment at him. Gary glanced at Kingsley and the scientist seemed speechless. He was sputtering, trying to talk.
"There are over fifty billion galaxies within our universe," he finally said. "Or at least that is what our astronomers believe."
"Sorry to contradict," said the Engineer. "There are many more than that. Many times more than that."
"More!" said Kingsley, faintly for him.
"The universes are four-dimensional," said the Engineer, "and they exist within a five-dimensional inter-space, perhaps another great super-universe with the universes within it taking the place of the galaxies as they are related to our universe."
"A universe within a universe," said Gary, nodding his head. "And might it not be possible that this super-universe is merely another universe within an even greater super-universe?"
"That might be so," declared the Engineer. "It is a theory we have often pondered. But we have no way of knowing. We have so little knowledge…"
A little silence fell upon the room, a silence filled with awe. This talk of universes and super-universes. This dwarling of values. This relegating of the universe to a mere speck of dust in an even greater place!
"The universes, even as the galaxies, are very far apart," the Engineer went on. "So very far apart that the odds against two of them ever meeting are almost incomprehensibly great. Farther apart than the suns in the galaxies, farther apart, relatively, than the galaxies in the universe. But entirely possible that once in eternity two universes will meet."
He paused, a dramatic silence in his thought. "And that chance has come," he said. "We are about to collide with another universe."
They sat in stunned silence.
