Clifford Simak - The World of the Red Sun

Ready, Bill? asked Harl Swanson. Bill Kressman nodded.

Then kiss 1935 good-bye! cried the giant Swede, and swung over the lever.

The machine quivered violently, then hung motionless in pitch blackness. In the snap of a finger the bright sunlight was blotted out and a total darkness, a darkness painted with the devils brush, rushed in upon the two men.

Electric lights glowed above the instrument boards, but their illumination was feeble against the utter blackness which crowded in upon the quartz windows of the machine.

The sudden change astounded Bill. He had been prepared for something, for some sort of change, but nothing like this. He half started out of his seat, then settled back.

Harl observed him and grinned.

Scared, he jested.

Hell, no, said Bill.

Youre traveling in time, my lad, said Harl. You arent in space any more. You are in a time stream. Space is curved about you. Cant travel in time when youre still in space, for space binds time to a measured pace, only so fast, no faster. Curve space about you, though, and you can travel in time. And when youre out of space theres absolutely no light, therefore, utter darkness. Likewise no gravity, nor any of the universal phenomena.

Bill nodded. They had worked it all out before, many, many times. Double wall construction of a strength to withstand the vacuum into which the flier would be plunged at the move of the lever which would snatch it out of space into the time stream. An insulation to guard against the absolute zero that would rule where there could be no heat. Gravity grids at their feet so that they would still be able to orient themselves when flung into that space where there was no gravity. An elaborate heating system to keep the motors warm, to prevent the freezing of gasoline, oil and water. Powerful atmosphere generators to supply air to the passengers and the motors.

It had represented years of work, ten years of it, and a wealth that mounted into seven figures. Time after time they had blundered, again and again they had failed. The discoveries they had made would have rocked the world, would have revolutionized industry, but they had breathed no word of it. They had thought of only one thing, time travel.

To travel into the future, to delve into the past, to conquer time, to this the two young scientists had dedicated all their labors, and at last success lay beneath their hands.

It was in 1933 they had at last achieved their goal. The intervening months were spent in experiments and the building of the combination flier-time machine.

Miniature fliers were launched, with the miniature time machines set automatically. They had buzzed about the laboratory, to suddenly disappear. Perhaps at this very instant they were whirling madly through un-guessed ages.

They managed to construct a small time machine, set to travel a month into the future. In a months time, almost to the second, it had materialized on the laboratory floor where it had dropped at the end of its flight through time. That settled it! The feasibility of time travel was proved beyond all doubt.

Now Harl Swanson and Bill Kressman were out in the time stream. There had been a gasp of amazement from the crowd, on the street, which had seen the giant tri-motored plane suddenly disappear into thin air.

Harl crouched over the instrument board. His straining ears could distinguish the wheezy mutterings of the three motors as, despite the elaborate precautions taken to safeguard them, the inexorable fingers of absolute zero clutched at their throbbing metal.

This was a dangerous way, but the only safe way. Had they remained on the surface to plunge into the time stream they might have halted to find themselves and their machine buried by shifting earth; they might have found a great building over them, they might have found a canal covering them. Here in the air they were safe from all that might occur beneath them in the passing centuries through which they sped at an almost unbelievable pace. They were being fairly hurled through time.

Furthermore, the great machine would serve as a means of travel in that future day when they would roll out of the time stream back into space again. Perhaps it might serve as a means of escape, for there was no foreknowledge to tell them what they might expect a few thousand years in the future.

The motors wheezed more and more. They were operating on a closed throttle. At full speed they might dash the propellers to bits.

However, they must be warmed up. Otherwise they would simply die. It would be stark tragedy to roll out into space with three dead engines. It would mean a crash which neither of them could hope to survive.

Give her the gun, Bill, said Harl in a tense voice.

Bill pushed the accelerator slowly. The motors protested, sputtered, and then burst into a roar. Here, in the machine, because of the artificial air, sound could be heard. Out in the time stream there could be no sound.

Harl listened anxiously, hoping fiercely that the propellers would stand.

Bill cut the acceleration and the motors, once more barely turning over, ran more smoothly.

Harl glanced at his wrist watch. Despite the fact they were in time, where actual time could not be measured by clocks, the little watch still ticked off the time-space seconds and minutes.

They had been out eight minutes. Seven minutes more and they must roll out of time into space.

Fifteen minutes was all that the tortured motors could stand of this intense cold and vacuum.

He glanced at the time dial. It read 2816. They had traveled 2816 years into the future. They should be well over 5000 when the fifteen minutes were at an end.

Bill touched his arm.

Youre sure were still over Denver?

Harl chuckled.

If we arent, we may find ourselves billions of miles out in space. Its a chance we have to take. According to all our experiments we should be in exactly the same position we were when we snapped into the time stream. We are occupying a hole in space. It should remain the same.

Their lungs began to ache. Either the atmosphere generators were failing or the air leakage out into the vacuum was greater than they had expected. Undeniably the air was becoming thinner. The motors still ran steadily, however. It must be a leakage from the cabin of the ship.

How long? bellowed Bill.

Harl glanced at his watch.

Twelve minutes, he reported.

The time dial read 4224.

Three minutes, replied Bill, I guess we can stand it. The motors are running all right. Its getting colder, though, and the airs pretty thin.

Leakage, said Harl gruffly.

The minutes dragged.

Bill tried to think. Here they hung, hypothetically, over the city of Denver. Less than a quarter of an hour ago, they were in the year 1935, now they were passing over years at a lightning-like speed a speed of over 350 years in each space-minute. They must now be in about the year 6450.

He glanced at his hands. They were blue. It was intensely cold in the cabin. Their heat was leaking leaking swiftly. It was hard to breathe. The air was rare too rare for safety. Suppose they became unconscious. Then they would freeze would drive endlessly through time. Frozen corpses, riding through the aeons. The earth beneath them would dissolve in space. New worlds might form, new galaxies be born as they whirled on in the time stream. The time needle would reach the pin, bend back upon itself and slip past the pin, to slam against the side of the dial, where it would still struggle to record the flight of the years.

He chafed his hands and glanced at the time dial. It read 5516.

A quarter of a minute, snapped Harl, his teeth chattering, his right hand on the lever, his wrist watch held in front of him.
