Silent Ark

Chapter 15: Taking on a Critical Mission

On the eighteenth day, the CERN committee held its first plenary meeting in an emergency bunker fifty meters underground.

Although it was called "all", only 73 people were actually able to attend.

The team consists of CERN's permanent staff, plus physicists, mathematicians, and information scientists urgently transferred from various European research institutions.

This also led to Yao Chong's transformation from a low-ranking specialist in the data analysis group to the chief of the "Cosmic Structural Anomaly" project team, and Liu Pan's appointment as a special consultant to the committee. During this period, he designed the "Cassandra," the social crisis early warning system that would later become famous in the Ark.

The rest—the rest of the world—eight billion people, are currently living on the surface of the earth in a way that is "almost but not quite right," unaware that their universe has been given a new look.

The meeting was chaired by Professor Chen Dunli, representative of Huaxia.

His metronome persona shattered completely after the whale fell—because the concept of "beat" requires time to flow at a uniform rate, and time is still not completely linear on the eighteenth day.

Sometimes 1.3 seconds of information are crammed into one second, and sometimes 0.7 seconds of information are crammed into one second.

He no longer taps his knee with the half of his ring finger that he injured in an experiment years ago, because he can no longer find a familiar and stable rhythm to tap it with.

He got straight to the point.

"The data collected from the global observation stations over the past eighteen days has been preliminarily analyzed. I need Liu Pan and Yao Chong to give their reports first. Liu Pan, your part."

Liu Pan stood up; he wasn't using PowerPoint.

He walked to the center of the conference room and closed his eyes.

Then he did something no one expected—he described the color.

"Some of you can see it, some of you can't. But I've been watching it since the day of the whale fall. It covered everything—the walls, the floor, the air, our skin. I spent eighteen days trying to understand what it was. Today I have the answer."

He opened his eyes.

"It's not a color, it's wrinkles."

He stretched out his right hand, making a pinching and pulling motion in the air—"You know, on a two-dimensional plane, if a three-dimensional object passes through the plane, what will a person on the plane see? They will see a cross-section. A two-dimensional shape that goes from nothing to something, from small to large, then from large to small, and finally disappears. Right?"

No one speaks.

"Now think about it the other way around. If something of a higher dimension were to pass through our three-dimensional space—what would we see?"

"A cross-section," Yao Chong chimed in. "A three-dimensional cross-section."

"Yes. But not a static cross-section. When a higher-dimensional object passes through, each of its 'slices' leaves a three-dimensional projection in our space—a continuous, changing projection—like a roll of film being projected frame by frame onto a screen. We can't see the higher-dimensional object itself, only the sequence of shadows it casts in lower-dimensional space."

Liu Pan paused for a moment.

"The color I saw—the membrane that permeates everything—is the latest frame of that shadow."

Someone in the conference room gasped.

It's not an exaggeration—it's also in a physical sense: whales' breathing rhythm is indeed not quite right compared to humans. When they inhale, the glottis closes at an angle of about 2 degrees, producing a sharper sound than before. Although it's not obvious, it's real.

"Are you sure?" Chen Dunli asked.

"Confirmed," Liu Pan said, "because I conducted eighteen consecutive days of observation. That 'color' wasn't static. It was changing. Slowly, continuously, in a way that couldn't be described by three-dimensional geometry. I recorded its morphological parameters—not the color parameters, but the topological parameters—connectivity, genus, Euler eigenvalues—every six hours—and then I discovered that the changes in these parameters weren't random."

He drew a curve on the table with his finger.

"It cycles in one period. The period is approximately 168 hours long. Seven days."

"Seven days?" Chen Dunli's half-finger twitched—it was his remaining rhythmic instinct, and also a habit he had developed over the years.

"Seven days," Liu Pan said. "And within this seven-day period, the topological parameters of that high-dimensional cross-section don't change smoothly. It has seven different stable states. Each stable state lasts about 24 hours, and then jumps to the next one within a few seconds. Seven stable states, a seven-day cycle."

"What do you want to say?" Professor Chen already had a preliminary guess, but he wanted to know more.

Liu Pan first glanced at Yao Chong, who was standing diagonally opposite, and then said, "What I want to say is—the higher-dimensional objects passing through our space are not a single piece. There are seven of them. Seven different higher-dimensional structures, each with a seven-day cycle, project their cross-sections into our three-dimensional space in turn. Like a rotating kaleidoscope—every time it turns an angle, a new pattern appears on the glass."

"Seven high-dimensional structures. A seven-day cycle."

"right."

"Corresponding to the seven days of the week."

"right."

The meeting room remained quiet for a long time.

Then Yao Chong spoke.

"More than seven," he said.

All eyes turned to him.

"What Liu Pan just said was seven, but that's only a part of it. We've compiled a list of twelve known numbers." Yao Chong turned the notebook in front of him around—it was covered with topological diagrams, densely packed with arrows and labels, looking like a madman's doodles. But if you looked closely, the direction of each line strictly followed some kind of algebraic rule.

"After the whale crashed, the laws of physics were not fully restored. What is the relationship between the restored parts—73% of the strong nuclear force, 98% of gravity, and the difference in the speed of light of 11 m/s? I spent eighteen days calculating it."

He pointed to a set of equations in his notebook.

"Yes. They satisfy a set of five simultaneous equations. Five equations, five unknowns. Each recovered physical constant can be expressed as a function of these five unknowns."

What do the five unknowns correspond to?

"These correspond to five independent parameter fields. They exist in our three-dimensional space, but cannot be directly observed—like dark matter. You can infer the existence of dark matter through gravitational effects, but you can't see it directly. Similarly, you can infer the existence of these five parameter fields through the offsets of physical constants, but you can't see them directly."

"What Liu Pan sees is a cross-section—the projection of a high-dimensional object into a low-dimensional space. What I deduce is a field—the residual influence of a high-dimensional object in a low-dimensional space. The cross-section is instantaneous and visual. The field is continuous and functional. They describe two different aspects of the same set of high-dimensional existences."

"So—" Chen Dunli said slowly, "seven, five."

"At least twelve," Yao Chong said. "Maybe more. But at least twelve."

How do you know they're not from the same batch?

"Because their mathematical structures are completely different." Yao Chong turned to the next page of his notebook.

There are two pictures on this page.

The image on the right shows a diagram of seven topological structures—each different, but all belonging to the same category: they have angular features, breaks, and singularities that cannot be smoothed.

The image on the left shows a schematic diagram of five topologies—each different, but belonging to another category: all are closed, smooth manifolds without singularities.

"The seven on the right—the seven Liu Pan described—belong to the category of 'non-smooth manifolds' in topology. They have wrinkles, cusps, and discontinuous jumps. In the language of physics, their information structure is lossy. Like an image that has been compressed too many times, when you zoom in, it's all pixelated."
