"True. But, Commander, when you buck odds like that and win, the thing to do is look for some factor that is cheating in your favor. If you took a pair of dice and started throwing sevens, one right after another--_for the next couple of thousand years_--you'd begin to suspect they were loaded." Benedict said nothing; he just waited expectantly. "There is only one thing that could have done it. Our ship." Leicher said it quietly, without emphasis. "What we know about the hyperspace, or superspace, or whatever it is we move through in ultradrive is almost nothing. Coming out of it so near to a star might set up some sort of shock wave in normal space which would completely disrupt that star's internal balance, resulting in the liberation of unimaginably vast amounts of energy, causing that star to go nova. We can only assume that we ourselves were the fuze that set off that nova." Benedict stood up slowly. When he spoke, his voice was a choking whisper. "You mean the sun--Sol--might...." Leicher nodded. "I don't say that it definitely would. But the probability is that we were the cause of the destruction of Alpha Centauri A, and therefore might cause the destruction of Sol in the same way." Benedict's voice was steady again. "That means that we can't go back again, doesn't it? Even if we're not positive, we can't take the chance." "Not necessarily. We can get fairly close before we cut out the drive, and come in the rest of the way at sub-light speed. It'll take longer, and we'll have to go on half or one-third rations, but we _can_ do it!" "How far away?" "I don't know what the minimum distance is, but I do know how we can gage a distance. Remember, neither Alpha Centauri B or C were detonated. We'll have to cut our drive at least as far away from Sol as they are from A." "I see." The commander was silent for a moment, then: "Very well, Dr. Leicher. If that's the safest way, that's the only way." Benedict issued the orders, while Leicher figured the exact point at which they must cut out the drive, and how long the trip would take. The rations would have to be cut down accordingly. Commander Benedict's mind whirled around the monstrousness of the whole thing like some dizzy bee around a flower. What if there had been planets around Centauri A? What if they had been inhabited? Had he, all unwittingly, killed entire races of living, intelligent beings? But, how could he have known? The drive had never been tested before. It couldn't be tested inside the Solar System--it was too fast. He and his crew had been volunteers, knowing that they might die when the drive went on. Suddenly, Benedict gasped and slammed his fist down on the desk before him. Leicher looked up. "What's the matter, Commander?" "Suppose," came the answer, "Just suppose, that we have the same effect on a star when we _go into_ ultradrive as we do when we come out of it?"
