lives?" "Yes." "Ackerman, you started this. Unwittingly, of course. Bombardment of Element X—which we call Temperon—produced a freak field of force that caused a division in the universal stream of time. It has never happened before and it will never happen again according to the probabilities—no one knows what happened. "This, Ackerman, produced a twin existance. Two probabilities that stem from a dual explosion in your laboratory. In one, there was a complete success to your work; in the other, there was total destruction of your effort. Not only did you split the world into twin existances through 'time', Ackerman, but you also split it definitely into twin camps of reasoning. Your work was based upon findings that came from countries that were enemies not many years before. Figuratively, you stood on the shoulders of scientific wisdom to prepare your manuscript of facts on the element temperon. "Your work was an indictment of any policy that would hamstring the free interchange of ideas, concepts, work, and success. It was living proof that all men contribute to the advancement of civilization whether they be good, not so good, bad, quick, dead, friend or one-time enemy. "The other existance, however, has your evidence that men were plodding through the uncharted seas of boundless energy and power—" "But I was not!" stated Ackerman. "You know that and your fellows know it. But your scientific fellows are a minority, and many of them doubt their own figures. They know only that something blew you and your laboratory off of the face of the earth, and they all wonder why—even those who claim to know that you were working with nothing dangerous. "Therefore, Ackerman, because you and your kind were obviously playing with a field of work that might cause the destruction of the universe, research is throttled and controlled to within an inch of its life. There is no leaping from an unfounded theory to cold mathematics to foregone conclusion like a fast double-play from short to second to first. To bombard a ten milligram sample of anything never before bombarded, the scientist must make ten ten-hour bombardments, adding one milligram each time." "Well—where do I come in?" asked Ackerman. "You have the answer to mankind's life in your brain," replied Blaine. "We need your help."
