The Other Tiger | Arthur C. Clarke (1953)

“It’s an interesting theory,” said Arnold, “but I don’t see how you could ever prove it.” They had come to the steepest part of the hill and for a moment Webb was too breathless to reply.

“I’m not trying to,” he said when he had gained his second wind. “I’m only exploring its consequences.”

“Such as?”

“Well, let’s be perfectly logical and see where it gets us. Our only assumption, remember, is that the universe is infinite.”

“Right. Personally I don’t see what else it can be.”

“Very well. That means there must be an infinite number of stars and planets. Therefore, by the laws of chance, every possible event must occur not merely once but an infinite number of times. Correct?”

“I suppose so.”

“Then there must be an infinite number of worlds exactly like Earth, each with an Arnold and Webb on it, walking up this hill exactly as we are doing now, saying these same words.”

The Haunted Space Suit | Arthur C. Clarke (1958)

The space suits we use on the station are completely different from the flexible affairs men wear when they want to walk around on the moon. Ours are really baby space ships, just big enough to hold one man. They are stubby cylinders, about seven feet long, fitted with low-powered propulsion jets, and have a pair of accordion-like sleeves at the upper end for the operator’s arms.

As soon as I’d settled down inside my very exclusive space craft, I switched on power and checked the gauges on the tiny instrument panel. All my needles were well in the safety zone, so I lowered the transparent hemisphere over my head and sealed myself in. For a short trip like this, I did not bother to check the suit’s internal lockers, which were used to carry food
and special equipment for extended missions.

It was at that moment, as I launched myself out into the abyss, that I knew that something was horribly wrong.

Reunion | Arthur C. Clarke (1971)

People of Earth, do not be afraid. We come in peace–and why not? For we are your cousins; we have been here before.

You will recognise us when we meet, a few hours from now. We are approaching the solar system almost as swiftly as this radio message. Already, your sun dominates the sky ahead of us. It is the sun our ancestors and yours shared ten million years ago. We are men, as you are; but you have forgotten your history, while we have remembered ours

We colonised Earth, in the reign of the great reptiles, who were dying when we came and whom we could not save. Your world was a tropical planet then, and we felt that it would make a fair home for our people. We were wrong. Though we were masters of space, we knew so little about climate, about evolution, about genetics…

Knock | Fredric Brown (1948)

“The last man on Earth sat alone in a room. There was a knock at the door.”

Fredric Brown, Knock

There is a sweet little horror story that is only two sentences long:

“The last man on Earth sat alone in a room. There was a knock on the door…”

Two sentences and an ellipsis of three dots. The horror, of course, isn’t in the two sentences at all; it’s in the ellipsis, the implication: what knocked at the door? Faced with the unknown, the human mind supplies something vaguely horrible.

But it wasn’t horrible, really.

Answer | Fredric Brown (1954)

Dwar Ev ceremoniously soldered the final connection with gold. The eyes of a dozen television cameras watched him and the subether bore throughout the universe a dozen pictures of what he was doing.

He straightened and nodded to Dwar Reyn, then moved to a position beside the switch that would complete the contact when he threw it. The switch that would connect, all at once, all of the monster computing machines of all the populated planets in the universe — ninety-six billion planets — into the supercircuit that would connect them all into one supercalculator, one cybernetics machine that would combine all the knowledge of all the galaxies.

Dwar Reyn spoke briefly to the watching and listening trillions. Then after a moment’s silence he said, “Now, Dwar Ev.”

Dwar Ev threw the switch. There was a mighty hum, the surge of power from ninety-six billion planets. Lights flashed and quieted along the miles-long panel.

Dwar Ev stepped back and drew a deep breath. “The honor of asking the first question is yours, Dwar Reyn.”

“Thank you,” said Dwar Reyn. “It shall be a question which no single cybernetics machine has been able to answer.”

He turned to face the machine. “Is there a God?”

The mighty voice answered without hesitation, without the clicking of a single relay. “Yes, now there is a God.”

Sudden fear flashed on the face of Dwar Ev. He leaped to grab the switch.

A bolt of lightning from the cloudless sky struck him down and fused the switch shut.


Fredric Brown (1906-1972) was an American science fiction, fantasy, and mystery fiction writer, who was well known for his use of humour and his mastery of the so-called “short-short” form of story-telling. His short-short story, “Answer”, was first published in 1954 in the collection Angels and Spaceships.

Sentry | Fredric Brown (1954)

He was wet and muddy and hungry and cold, and he was fifty thousand light-years from home.

A strange blue sun gave light and the gravity, twice what he was used to, made every movement difficult.

But in tens of thousands of years this part of war hadn’t changed. The flyboys were fine with their sleek spaceships and their fancy weapons. When the chips are down, though, it was still the foot soldier, the infantry, that had to take the ground and hold it, foot by bloody foot. Like this damned planet of a star he’d never heard of until they’d landed him there. And now it was sacred ground because the aliens were there too. The aliens, the only other intelligent race in the Galaxy… cruel, hideous and repulsive monsters.

Contact had been made with them near the center of the Galaxy, after the slow, difficult colonization of a dozen thousand planets; and it had been war at sight; they’d shot without even trying to negotiate, or to make peace.

Now, planet by bitter planet, it was being fought out.

He was wet and muddy and hungry and cold, and the day was raw with a high wind that hurt his eyes. But the aliens were trying to infiltrate and every sentry post was vital.

He stayed alert, gun ready. Fifty thousand light-years from home, fighting on a strange world and wondering if he’d ever live to see home again.

And then he saw one of them crawling toward him. He drew a bead and fired. The alien made that strange horrible sound they all make, then lay still.

He shuddered at the sound and sight of the alien lying there. One ought to be able to get used to them after a while, but he’d never been able to. Such repulsive creatures they were, with only two arms and two legs, ghastly white skins and no scales.


Fredric Brown (1906-1972) was an American science fiction, fantasy, and mystery fiction writer, who was well known for his use of humour and his mastery of the so-called “short-short” form of story-telling. “Sentry” is one of his shortest and best-known examples of this form, and was first published in the February 1954 issue of Galaxy Science Fiction.
