"A nebula is the vastest thing in all our universe, and the most mysterious. A gigantic mass of glowing gas that stretches across countless billions of miles of space, its mighty bulk flames in the heavens like a universe on fire. Beside its vast dimensions all the suns of the Galaxy are but as sparks beside a great, consuming blaze. Here and there in our Galaxy lie these mighty mysteries, these flaming nebulae, and mightiest of all is that one which we call the Orion Nebula, that gigantic globe of flaming gas which measures light-years in diameter, burning in giant splendor at the Galaxy's heart. We know that the great nebula is growing slowly smaller, that through the eons it contracts to form new blazing stars, but what its constitution may be, what mysteries it may hide, has never been known, since it would be annihilation for any ship to approach too near to its fiery splendor, and all our interstellar traffic has detoured always far around its flaming mass. Because of that inaccessibility no large attention has ever been paid to the great nebula, nor would there be now, had not something been discovered but now by our scientists regarding it which seems to herald the end of our universe.
"As I have said, this nebula, this gigantic globe of flaming gas, lies practically motionless in space at the heart of our Galaxy. A few weeks ago, however, it was discovered by our astronomers that the great flaming sphere of the nebula had begun slowly to revolve, to spin, and that as the days went by it was spinning faster and faster. Through the weeks since then our astronomers have watched it closely, and ever faster it has spun, until now it is revolving at a terrific rate, a rate that is still steadily increasing. And that accelerating spin of the huge nebula must result, inevitably, in the doom of our universe.
"For our scientists have calculated that within two more weeks the nebula's rate of spin will have become so great that it will no longer be able to hold together, that it will disintegrate, break up, its gigantic masses of incandescent gases flying off in all directions like the pieces of a bursting fly-wheel. And those colossal clouds of flaming gas, flying out through our Galaxy, our universe, will inevitably sweep over and destroy countless thousands of our suns and worlds, annihilating the worlds like midgets in candle-flame, changing the suns into nebulous masses of flaming gas like themselves, smashing gigantically through and across the Galaxy and destroying the gravitational balance of its whirling suns and worlds until in a great chaos of crashing stars and planets our universe ends as a vast, cosmic wreck, our organizations and our civilizations gone forever!"
The Council Chief paused for a moment, and in that moment there was silence over all the great hall, a silence unnatural, terrible, unbroken by any slightest sound. I saw the members about me leaning forward, gazing tensely toward the Council Chief, and when he spoke again his words seemed to come to us through that strained silence as though from some remoteness of distance.
"Terrible as this peril is." he was saying, "we must face it. Flight is impossible, for where could we flee? We have but one chance to save ourselves, our universe, and that is to halt the spinning of the great nebula before the few days left us have passed, before this cosmic cataclysm takes place. Some extraordinary force or forces have set the great nebula to spinning thus, and if we could venture out to the nebula, discover the nature of those forces, we might be able to counteract them, to stop the nebula's spin and save our suns and worlds.
"It is impossible, of course, for any of our ordinary interstellar ships to attempt this, since any that approached the great nebula would perish instantly in its flaming heat. It chances, however, that some of our scientists here have been working for months on the problem of devising new heat-resistant materials, materials capable of resisting temperatures which would destroy other substances. They have worked on the principle that heat-resistance is a matter of atomic structure. Steel, for instance, resists heat and fire better than wood because its atomic structure, and arrangement of its atoms, is more stable, less easily broken up. And following this principle they have devised a new metallic compound or alloy whose atomic structure is infinitely more stable than that of any material known to us previously, and which is able to resist temperatures of thousands of degrees.
"Of this heat-resistant material an interstellar cruiser was constructed, a cruiser which could venture into regions of heat where other ships would perish instantly. It had been the intention to use this cruiser to explore solar coronas, but at my order it has been brought here to the Council Hall, equipped for action. For it is my intention to use this cruiser to venture out close to the great nebula's flaming fires, which it alone can do, and make a last effort to discover and counteract whatever force or forces there are causing the accelerating spin of the nebula that means doom to us. The cruiser itself is not a large one, and with its present equipment can hold but three for this trip, three on whom must rest all the chances for escape of our universe. And these three I intend to choose now from among you, three whose past careers and interstellar experience make them best fitted for this hazardous and all-important trip."
He paused again, and over the massed members there swept now a whisper of excitement, a low babel of a thousand unlike voices that stilled suddenly as the Council Chief again spoke, his high, clear voice sounding across the great room like a whipcrack.
"Sar Than of Arcturus!"
As he called the name a single figure rose from among the members to my left, a bulbous body supported above the ground by four powerful thick tentacles of muscle which served both as arms and legs, while set upon the body was the round, neckless head, with its two quick, intelligent eyes and narrow mouth. A moment the Arcturian paused on rising, then stepped out into the aisle and down toward the central platform. And now the voice of the Council Chief cut again across the rising clamor of the members.
"Jor Dahat of Capella!"
Before me now another figure rose, one of the strange plant-men of Capella, of the people who had evolved to intelligence and power from the lower plant-races there; his body an upright cylinder of smooth, fibrous flesh, supported by two short, thick legs and with a pair of powerful upper arms, above which was the conical head whose two green-pupiled eyes and close-set ears and mouth completed the figure. In a moment he too had strode down toward the platform, and then, over the tumultuous shouts of those in the great hall, which had risen now to a steady roar of voices, there came the clear voice of the Council Chief, with the third name.
"Ker Kal of Sun-828!"
For a moment I sat silent, my brain whirling, the words of the Council Chief drumming in my ears, and then heard the excited voices of the members about me, felt myself stumbling to my feet and down the aisle in turn toward the platform. Beating in my dazed ears now was the tremendous shouting clamor of all the gathered members, and beneath that surging thunder of thousands of voices I sensed but dimly the things about me, the Arcturian and Capellan beside me, the figure of the Council Chief on the platform beyond them. Then I saw the latter raise a slender arm, felt the uproar about me swiftly diminishing, until complete silence reigned once more. And then the Council Chief was speaking again, this time to us.
