Black-out

In Short

This short story presents a poignant meditation on scientific idealism and the fragility of civilizations. Set on a dying Mars, it follows an aging astronomer, Thak, who builds a final telescope to signal a seemingly advanced blue planet. Thak believes the lights he sees on Earth are intentional signals of a superior, peaceful society. Through his lens, however, he realizes that the flickering lights are not a beacon of hope but a reflection of a parallel destruction. It endures as a haunting warning about the projection of our own desires onto the unknown.

The Story

On a Mars depleted by war and encroaching wilderness, the astronomer Thak oversees the completion of a new telescope. He is the last of his kind dedicated to scientific inquiry, having persuaded the weary elders to grant him the resources for this instrument, which he views as a final lifeline for his race. Thak is met with constant derision from Mitfpa, a military overseer who views the project as a frivolous waste of labor. Thak argues that their only chance for survival lies in reaching out to the inhabitants of the brilliant blue planet in the night sky. He believes these beings are highly advanced and peaceful, citing his observation of vast, systematic light signals covering the Earth's surface as evidence of their sophisticated communication.

Thak’s students, spherical beings with delicate tentacles, observe his work with youthful enthusiasm. They study the theories of the physicist Mor Gran, which confirm that the Martian race is in its final decline. Thak maintains that if they can establish contact with the humans, their superior wisdom might provide the secret to ending the wars that have crippled Mars. He explains to his students that the lights on Earth are signals, dismissing their naive suggestions that they might be city lights by arguing that cities would be roofed and thus unable to show light to space.

As the telescope is finally calibrated, Thak directs it toward the third planet. The students are mesmerized by the view, which reveals the continents and islands of Earth in stunning detail. They watch in awe, expecting to find the vibrant, signaling civilization Thak has promised. However, as the image resolves with perfect clarity, a heavy silence falls over the group. The students notice that the expected patterns of light are absent. Rofan, one of the more observant pupils, begins to sense that the reality does not match their mentor’s hopeful narrative.

Thak, who has been peering at the image with growing dread, is forced to confront the truth he had tried to suppress. He had previously convinced himself that his small, inferior telescopes were simply failing to capture the fading lights. Now, with the new instrument, he sees the terrifying reality: the lights are not signals, but the dying flickers of human cities. One by one, the lights across the globe are going dark. Thak realizes that the "superior" race he pinned his hopes on is suffering the same fate as his own. His final proclamation is one of total despair; the blackout of the lights on Earth signifies the inevitable, final blackout of life on Mars.

How It Unfolds

The astronomer’s ambition Thak secures the construction of a powerful new telescope, seeing it as the last hope for a dying Mars. He fights off the cynicism of the military, insisting that the survival of his race depends on reaching out to a beacon of light on the blue planet.

The promise of the blue planet Thak teaches his students that the lights seen on Earth are intentional signals of a superior, peaceful intelligence. He refuses to entertain mundane explanations, insisting that their existence is a testament to an advanced society that holds the keys to Martian salvation.

The revelation of the lens The group gathers around the quartz bowl to view the third planet with newfound clarity. As the image stabilizes, the students expect to see a thriving, signaling civilization but instead encounter a confusing, silent expanse.

The final darkness Thak acknowledges that the lights he once saw were merely the city lights of a failing civilization, now extinguished by war or decline. He realizes that there is no help coming, as the same destruction that claimed his people has now fully consumed the Earth.

The People

Thak is the story’s tragic visionary, an old astronomer who serves as the last bastion of scientific hope on a decaying world. He is driven by a profound, almost desperate need to believe in a savior, leading him to interpret reality through the lens of his own bias. By the end, his intellectual vanity is stripped away, leaving him to face the extinction of his race without the comfort of his delusions.

Mitfpa serves as the voice of brutal pragmatism. As a military overseer, he views science as a triviality that diverts resources from the immediate, animal struggle for survival. He is not a complex character, but he highlights the fatalistic environment that has pushed Mars to the brink of collapse.

Rofan, one of Thak’s students, represents the next generation’s dawning awareness. He is intellectually curious and open-minded, initially deferring to Thak’s authority but eventually developing the critical faculty to recognize that something is fundamentally wrong with their observations. His role is to bridge the gap between Thak’s blind faith and the cold reality of the telescope’s view.

In Its Own Voice

"You have ruined progress and science forever."

Thak confronts the military overseer, Mitfpa, blaming the warmongers for the systematic collapse of Martian civilization.

"The lights were lowered, and into the bowl moved a blurred sphere."

Thak prepares his students for the momentous reveal as the telescope finally brings the third planet into focus.

"And--the blacking out of those lights means a blackout of life on Mars."

After realizing the lights on Earth were actually fading cities, Thak reaches the harrowing conclusion that his race’s hope was a fatal illusion.

What It's Really About

The story is a stark exploration of the "savior complex" and the dangerous tendency to project human—or, in this case, Martian—desires onto the cosmos. Thak’s tragedy is not just the death of his planet, but his refusal to see the evidence of destruction right in front of him, preferring the fantasy of a superior, distant society to the grim reality of a dying one. It questions whether science, when divorced from objective observation and tainted by desperation, can actually blind us to the truth. The book argues that civilization’s greatest enemy is often the denial of its own fragility, suggesting that we are all prone to seeking external salvation rather than facing the consequences of our own internal decay.

Why Read It Today

This story will appeal to readers who enjoy the melancholy, atmospheric tone of mid-century science fiction. It is not an action-heavy tale but a slow-burn study of a single, devastating moment of realization. The prose is clean and direct, moving with a steady, inevitable gravity toward its conclusion.

Readers today might find the "Martian" setting and the descriptions of the characters—spherical beings with tentacles—to be a charming artifact of a bygone era of space fiction. However, the emotional core remains sharp; the story captures the specific, chilling sensation of watching a light go out that you didn't realize was your own. The period attitudes toward "superior wisdom" and the nature of technological progress reflect the anxieties of 1943, when the world was embroiled in its own global blackout. While the pacing is brisk and the scope is intimate, the story stays with you because it confronts a universal fear: that we are alone in the universe, and that the "signals" we think we see from others are often just reflections of our own fading hopes. It is a brief, somber read that successfully distills the tragedy of a civilization into a handful of pages.
