“You’ve lost me,” Gino sighed.
“Let me see if I get it,” Dan said. “It sounds like you are saying that things are just as we think we see them, and our thinking keeps them that way. Like that tree in the quad I remember from college.”
“Again not correct, but an approximation you may hold if it helps you to clarify your thinking. It is a phenomenon that I have long suspected, certain observations in the speed of light that might be instrumentation errors, gravitic phenomena, chemical reactions. I have suspected something, but have not known where to look. I thank you gentlemen from the bottom of my heart for giving me this opportunity at the very end of my life, for giving me the clues that may lead to a solution to this problem.”
“Solution. …” Gino’s mouth opened. “Do you mean there is a chance we can go back to the world as we knew it?”
“Not only a chance—but the strongest possibility. What happened to you was an accident. You were away from the planet of your birth, away from its atmospheric envelope and, during parts of your orbit, even out of sight of it. Your sense of reality was badly strained, and your physical reality and the reality of your mental relationships changed by the death of your comrade. All these combined to allow you to return to a world with a slightly different aspect of reality from the one you have left. The historians have pinpointed the point of change. It occurred on the , the day that President Roosevelt died of pneumonia.”
“Is that why all those medical questions about my childhood?” Dan asked. “I had pneumonia then, I was just a couple of months old, almost died, my mother told me about it often enough afterwards. It could have been at the same time. It isn’t possible that I lived and the president died … ?”
Einstein shook his head. “No, you must remember that you both lived in the world as you knew it. The dynamics of the relationship are far from clear, though I do not doubt that there is some relationship involved. But that is not important. What is important is that I think I have developed a way to mechanically bring about the translation from one reality aspect to another. It will take years to develop it to translate matter from one reality to a different order, but it is perfected enough now—I am sure—to return matter that has already been removed from another order.”
Gino’s chair scraped back as he jumped to his feet. “Professor—am I right in saying, and I may have got you wrong, that you can take us and pop us back to where we came from?”
Einstein smiled. “Putting it as simply as you have, major … the answer is yes. Arrangements are being made now to return both of you and your capsule as soon as possible. In return for which we ask you a favor.”
“Anything, of course,” Dan said, leaning forward.
“You will have the reality-translator machine with you, and microcopies of all our notes, theories and practical conclusions. In the world that you come from all of the massive forces of technology and engineering can be summoned to solve the problem of mechanically accomplishing what you both did once by accident. You might be able to do this within months, and that is all the time that there is left.”
“Exactly what do you mean?”
“We are losing the war. In spite of all the warning we were not prepared, we thought it would never come to us. The Nazis advance on all fronts. It is only a matter of time until they win. We can still win, but only with your atom bombs.”
“You don’t have atomic bombs now?” Gino asked.
Einstein sat silent for a moment before he answered. “No, there was no opportunity. I have always been sure that they could be constructed, but have never put it to the test. The Germans felt the same, and at one time even had a heavy water project that aimed towards controlled nuclear fission. But their military successes were so great that they abandoned it along with other far-fetched and expensive schemes such as the hollow-globe theory. I myself have never wanted to see this hellish thing built, and from what you have told about it, it is worse than my most terrible dream. But I have approached the President about it, when the Nazi threat was closing in, but nothing was done. Too expensive. Now it is too late. But perhaps it isn’t. If your America will help us, the enemy will be defeated. And after that, what a wealth of knowledge we shall have once our worlds are in contact. Will you do it?”
“Of course,” Dan Coye said. “But the brass will take a lot of convincing. I suggest some films be made of you and others explaining some of this. And enclose some documents, anything that will help convince them what has happened.”
“I can do something better,” Einstein said, taking a small bottle from a drawer of the table. “Here is a recently developed drug, and the formula, that has proved effective in arresting certain of the more violent forms of cancer. This is an example of what I mean by the profit that can accrue when our two worlds can exchange information.”
Dan pocketed the precious bottle as they turned to leave. With a sense of awe they gently shook hands with the frail old man who had been dead many years in the world they knew, to which they would be soon returning.
The military moved fast. A large jet bomber was quickly converted to carry one of the American solid-fuel rocket missiles. Not yet operational, it was doubtful if they ever would be at the rate of the Nazi advance. But given an
