The altimeter read 10,000 feet, and the horizon was still at eye level.
Mercer noted this with the same calm precision he’d used to note a thousand other details in the past six minutes of vertical ascent. Airspeed: 340 knots. Rate of climb: 4,200 feet per minute. Engine temperature: nominal. Fuel consumption: exactly as predicted.
Horizon: exactly where it shouldn’t be.
The rocket was a beautiful machine—all thrust and grace, designed for high-altitude reconnaissance that the Directorate claimed was essential for “monitoring atmospheric conditions.” Mercer had flown her a dozen times before, always following approved flight paths, always staying within approved altitudes, always filing approved reports that said exactly what the Directorate wanted to hear.
He’d been very good at his job.
He’d also been very good at lying to himself.
The sky outside the viewport was deepening from blue to a darker shade—not quite the black of “space” that the textbooks promised, but darker nonetheless. The sun hung in the sky like a spotlight, closer than it should be if it were really 93 million miles away, moving in patterns that made sense only if you stopped believing what you’d been taught and started believing what you could see.
At 10,000 feet, the horizon should have dropped below eye level. That’s what the math said. That’s what the curvature of a ball-shaped Earth demanded. Eight inches per mile squared, they’d taught him at the academy. Simple geometry. Inescapable physics.
The horizon remained stubbornly, impossibly level with his eyes.
Just like it had three years ago.
The observation deck at Coastal Station Seven was the highest point for two hundred miles—a tower that rose 800 feet above the ocean, designed to give meteorologists an unobstructed view of incoming weather patterns.
Mercer had been there on a routine inspection, checking equipment, filing reports, doing the thousand small tasks that kept the Directorate’s machinery running smoothly. He’d stepped out onto the deck with his morning coffee, looked out at the ocean, and noticed something that would eventually cost him his career, his reputation, and possibly his life.
The horizon was at eye level.
He’d blinked, certain he was seeing it wrong. He was 800 feet up. The horizon should have dropped. He should have been looking down at it, even slightly. That’s what happened when you stood on a ball. The higher you went, the more the horizon fell away beneath you.
Except it didn’t.
He’d pulled out his personal tablet—not the Directorate-issued one, but the old civilian model he’d kept from before his academy days—and done the calculation. On a sphere with a radius of 3,959 miles, standing at 800 feet of elevation, the horizon should be approximately 34.6 miles away and should appear to drop by roughly 0.5 degrees below eye level.
It was a small angle. Barely noticeable, perhaps.
But it should have been there.
He’d spent the next hour taking measurements. He’d used a level—an actual bubble level from the maintenance kit—to establish a true horizontal line. Then he’d sighted along it toward the horizon.
The horizon met the level perfectly.
“Captain Mercer?” A technician had appeared at his elbow, looking concerned. “Are you all right? You’ve been staring at the ocean for an hour.”
“Tell me something,” Mercer had said, not looking away from the horizon. “We’re on a ball, right? A sphere. Spinning through space.”
“Of course, sir.” The technician had sounded confused. “Everyone knows that.”
“So the horizon should curve away from us. The higher we go, the more it should drop below eye level.”
“I... suppose so? I’m not really a physics person, sir.”
“Look at it,” Mercer had said, gesturing at the endless line where ocean met sky. “Does that look like it’s curving away from us? Does it look like it’s dropping?”
The technician had looked. Really looked, perhaps for the first time in his life.
“No,” he’d said slowly. “No, it doesn’t.”
“No,” Mercer had agreed. “It doesn’t.”
He’d filed his report that evening. A careful, measured document noting the “unexpected observational data” and requesting clarification on the “apparent discrepancy between theoretical models and observed reality.”
The response had come within six hours.
“Captain Mercer is reminded that atmospheric refraction can create optical illusions at high altitudes. The curvature of the Earth is well-established scientific fact, confirmed by centuries of observation and measurement. Further reports questioning established science will be noted in the Captain’s permanent record. Trust in the Directorate. Trust in the science.”
The technician who’d been with him on the observation deck had been transferred to a facility in the interior the next day.
Mercer had never seen him again.
The altimeter read 12,000 feet now. The rocket was still climbing, still eating through fuel at a rate that would give Sarah a heart attack if she were watching the telemetry.
The horizon was still at eye level.
Mercer smiled grimly. Three years ago, that observation had been the first crack in the wall. The first moment when the official narrative had collided with observable reality and shattered into a thousand pieces that no amount of “atmospheric refraction” could glue back together.
He’d started looking after that. Really looking. At the ocean that always found its level, no matter how large the body of water. At the distant landmarks that should have been hidden behind the curve but remained stubbornly visible. At the sun that moved in circles overhead like a spotlight on a track, not like a distant star around which the Earth supposedly orbited.
At the stars themselves, which seemed far too close and moved in patterns that made sense only if they were attached to something—something solid, something rotating above the Earth like lights on a great dome.
The Directorate had explanations for all of it. Refraction. Perspective. Optical illusions. The limitations of human perception. The need to trust the experts, the scientists, the people who knew better than to believe their own lying eyes.
Mercer had tried to believe them. He’d wanted to believe them.
But the horizon had remained level, and the questions had remained unanswered, and eventually he’d found himself in a bookshop that wasn’t supposed to exist, reading texts that had been forbidden for two hundred years, learning words like “firmament” and “foundation” and “the circle of the Earth.”
Learning that he wasn’t crazy.
Learning that he wasn’t alone.
The altimeter read 15,000 feet. The air was thinner here, the sky darker. The rocket’s engines hummed with perfect efficiency, carrying him higher, closer to whatever waited above.
Mercer checked his instruments, adjusted his heading, and increased thrust.
Twenty thousand feet was next.
And he had a feeling that what he’d see there would make the horizon anomaly look like a footnote.
