"I don't know exactly what to make of this," he said thoughtfully. "We are so far away from the earth that even the fixed stars are unrecognizable. The power was on exactly forty-eight hours, since that is the life of that particular bar under full current. We should still be close to our own solar system, since it is theoretically impossible to develop any velocity greater than that of light. But in fact, we have. I know enough about astronomy to recognize the fixed stars from any point within a light-year or so of the sun, and I can't see a single familiar star. I never could see how mass could be a function of velocity, and now I am convinced that it is not. We have been accelerating for forty-eight hours!" He turned to Dorothy. "While we were unconscious, Miss Vaneman, we had probably attained a velocity of something like seven billion four hundred thirteen million miles per second, and that is the approximate speed at which we are now traveling. We must be nearly six quadrillion miles, and that is a space of several hundred light-years--away from our solar system, or, more plainly, about six times as far away from our earth as the North Star is. We couldn't see our sun with a telescope, even if we knew which way to look for it." * * * * * At this paralyzing news, Dorothy's face turned white and Margaret Spencer quietly fainted in her seat. "Then we can never get back?" asked Dorothy slowly. At this question, Perkins' self-control gave way and his thin veneer of decency disappeared completely. "You got us into this whole thing!" he screamed as he leaped at Dorothy with murderous fury gleaming in his pale eyes and his fingers curved into talons. Instead of reaching her, however, he merely sprawled grotesquely in midair, and DuQuesne knocked him clear across the vessel with one powerful blow of his fist. "Get back there, you cowardly cur," he said evenly. "Even though we are a long way from home, try to remember you're a man, at least. One more break like that and I'll throw you out of the boat. It isn't her fault that we are out here, but our own. The blame for it is a very small matter, anyway; the thing of importance is to get back as soon as possible." "But how can we get back?" asked Perkins sullenly from the corner where he was crouching, fear in every feature. "The power is gone, the controls are wrecked, and we are hopelessly lost in space." "Oh, I wouldn't say 'hopelessly,'" returned the other, "I have never been in any situation yet that I couldn't get out of, and I won't be convinced until I am dead that I can't get out of this one. We have two extra power bars, we can fix the board, and if I can't navigate us back close enough to our solar system to find it, I am more of a dub than I think I am. How about a little bite to eat?" "Show us where it is!" exclaimed Dorothy. "Now that you mention it, I find that I am starved to death." DuQuesne looked at her keenly.
