“ Those paths could not be explained by all the physicists and all the astronomers in the Five World Federation. They possessed the properties of light, but they were rigid bands like a tube or a solid pillar from which only the faintest of rays escaped; and they completely shut off the heavens behind them. They had, moreover, singular properties which could not be described, as if a new force were embodied in them.
Hour after hour humanity watched the spectacular progress of the dark star, watched those mysterious and threatening paths of light that flowed from the invader. ”

“ The dark star was gone. Somewhere far out in the abysses of the universe, a runaway world plunged headlong at ever-mounting speed to uncharted regions under its double acceleration of attraction and repulsion. ”

“ Under foot, they disintegrated into little pulpy lumps of inert metal.
In a trice he broke beyond the circle and darted to the control-panel. One quick glance showed him that the roof was now scarcely a half dozen yards above. With fingers that fumbled in haste at tiny levers and dials, he spun several of them—the repulsion-ray full—the attraction-ray full. And when they were set, he picked up the bar he had dropped and smashed the controls so that they were helplessly jammed. He could almost feel the planet catapult through the heavens. ”

“ Phobar's mind did not function—but his legs moved regularly. In the grasp of this mental, metal monster he was a mere automaton. Phobar noticed idly that he had to step down from a flat disk a dozen yards across. By some power, some tremendous discovery that he could not understand, he had been transported across millions of miles of space—undoubtedly to the dark star itself! ”

“ At two-ten he was thunderstruck by a special announcement sent from the Central Bureau to every observatory and astronomer of note throughout the world, proclaiming the discovery of an ultra-Plutonian planet. Phobar was incredulous. For centuries it had been proved that no planet beyond Pluto could possibly exist.
With feverish haste, Phobar ran to the huge telescope and rapidly focused it where the new planet should be. Five hundred million miles beyond Neptune was a flaming path like the beam of a giant searchlight that extended exactly to the eighth solar planet. Phobar gasped. ”

“ Already the pair had left the mountain-high titan city far behind; they rippled across the smooth, black surface of Xlarbti, and bore like rifle bullets down on the swiftly looming laboratory. In a few minutes it would be too late forever. Now the lost Greek words burst into Phobar's mind, and, hoping against hope, he thought in Greek word-pictures which his captor could not understand. He weighed chances, long shots. Into his brain flashed an idea.... But they were upon the laboratory; a stupendous door dissolved weirdly into shimmering haze; they sped through. ”

“ Yet even at that tremendous speed, it took us years to cross from our universe to yours. If we had encountered even a planetoid at that enormous rate, we would probably have been annihilated in white-hot death. But we had planned well, and there are no superiors to our stellar mechanics, our astronomers, our scientists.
"When we finally hurtled from the black void into your universe, we found what we had only dared hope for: a young universe, with many planets and cooling worlds rich in radium ores, the only element in your scale that can help to replenish our vanishing energy. ”

“ The full strength of our repulsion-force directed against any single world necessarily turns it into a liquid or gaseous state depending on various factors. Your planet Neptune was pulled out of the solar system by the attraction of Xlarbti's mass. The flame-paths, as you call them, are directed streams of energy for different purposes: the one to the sun supplies us, for instance, with heat, light, and electricity, which in turn are stored up for eventual use.
"The orange-ray that you felt is one of our achievements. ”

“ But we, who are so much older and greater than you, have for so long studied the nature of the other universes that we can enter and leave them at will, taking what we wish, doing as we wish, creating or destroying worlds whenever the need arises, coming and hurtling away when we choose.
"There is no vegetable life in our universe. ”

“ We could easily wipe out all the dwellers on Earth and mine the ores ourselves. But that would be a needless waste of our powers, for since you can not defy us, and since the desire for life burns as high in you as in us and as it does in all sensate things in all universes, your people will save themselves from death and save us from wasting energy by mining the ores for us. ”

“ At this high range, metals of complex kinds exist. There is none of what you call water, no vegetable world, no animal kingdom. Instead, there are energies, forces, rays, and waves, which are food to us and which nourish our life-stream just as pigs, potatoes, and bread are food to you.
"Trillions of years ago in your time-calculation, but only a few dozen centuries ago in ours, life arose on the giant world Kygpton in our universe. ”

“ And when everything was prepared, we destroyed the dead-field by duplicate control from Xlarbti, turned our repulsion-power on full against the now useless and dying giant world Kygpton, and swung upon our path.
"But our whole universe is incredibly old. It was mature before ever your young suns flamed out of the gaseous nebulæ, it was decaying when your molten planets were flung from the central sun, it was dying before the boiling seas had given birth to land upon your sphere. ”

“ But we are of a different universe, on a different scale from yours, a trillion light-years away in space, eons distant in time. The natural laws which govern us differ from those controlling you. In our universe, you would be hopelessly lost, completely helpless, unless you possessed the knowledge that your people will not attain even in millions of years. ”

“ But already our ancestors had mastered the forces of our universe, had made inventions that are beyond your understanding, had explored the limits of our universe in space-cars that were propelled by the free energies in space and by the attracting-repelling influences of stars.
"The metal inhabitants of Kygpton employed every invention they knew to accomplish an engineering miracle that makes your bridges and mines seem but the puny efforts of a gnat. They blasted all the remaining ores of Sthalreh from the surface and interior of Kygpton and refined them. ”

“ Rioting mobs drowned out the chant of religious fanatics who hailed Judgment Day. Great fires turned the air murky and flame-shot. Machine guns spat regularly in city streets; looting, murder, and fear-crazed crimes were universal. Civilization had completely vanished overnight. ”

“ Unless something speedily occurred to check the onrush of the dark star, it was prophesied that the laws governing the planetary system would run to a new balance, and that in the ensuing chaos the whole group would spread apart and fall toward the gulfs beyond the great surrounding void. ”

“ Half your universe we have already deprived of its ores. Your Earth has more that we want. Then we shall continue on our way, to loot the rest of the worlds, before passing on to another universe. We are a planet without a universe. We will wander and pillage until we find a universe like the one we come from, or until Xlarbti itself disintegrates and we perish. ”

“ The tides roared higher than they ever had before; for every thousand people drowned on the American seaboards, a hundred thousand perished in China and India. Dead volcanoes boomed into the worst eruptions known. ”
