Luna's astonishment stemmed from the fact that these things were actually alive on the Martian surface.
Keep in mind that the surface is cold, dry, and lacks any atmosphere.
Yet these ferns had grown. Although they looked withered, as a biologist, Luna confirmed that they were indeed alive.
They felt leathery, unlike dry grass that would crumble at a touch.
"This is highly unusual; there's essentially no water here."
Water is the source of life. This might not be true for life forms based on methane, for example, but for Earth organisms, it's an absolute truth.
Yet these ferns seemed to break this truth...or so it seemed.
Luna instructed Ayla to use a retrieval beam to transport this specimen to the ship for study. However, she realized with some dismay that the Potato Chip lacked research equipment.
Fortunately, Ayla had a miniature factory—a further miniaturization of the factory's size, resembling a large box.
A 20x20x20 centimeter cubic object, weighing about 28 kilograms, began changing shape as soon as it was placed on the ground, expanding into a 1.4x1x1 meter rectangular structure.
This rectangular structure extended a tube downwards, penetrating the ground and working like a vacuum cleaner.
The Martian soil contained numerous substances. These substances were extracted and analyzed by the miniature factory, which expanded itself, creating a complete production line before beginning to manufacture equipment.
This didn't take long. Luna didn't even wait 100 hours before an electron microscope appeared in her hand.
This electron microscope had a resolution of 0.004 nanometers—overkill for biological research, but Luna only needed to see the cellular structure of this fern.
Luna observed this fern through the electron microscope for three days and nights, finally discovering its mystery.
It wasn't that it didn't need water; it created its own internal water cycle. With only a tiny amount of water, it could grow. Its leaves contained no water; the entire structure had only one tube—20 times thinner than a human hair—maintaining the water supply.
This tube absorbed surrounding nutrients, expelling waste outside the body to form visible leaf-like structures.
Its structure was extremely simple, even rudimentary, yet miraculous because it evolved naturally.
"Plants, through constant subtraction, can survive in space."
Luna studied how this fern reproduced. She discovered that its reproduction method was similar to that of the immortal jellyfish—constant death and rebirth, achieving a kind of immortality.
"It could be that the robots accidentally lost some ice crystals while transporting ice, and the timing of their arrival might be related to the robots' tracks."
"This is the allure of nature."
Luna enjoyed this kind of exploration.
This gave Luna a very interesting idea.
"Ayla, do you think plants have science and technology, and civilizations?"
Ayla thought for a moment and answered, "Plants probably have civilizations because they are living beings that can interact. This civilization is very primitive, but to say science and technology...I don't think you mean science and technology in quotes, Luna. You mean real science and technology, and I don't know."
If plants possessed advanced technology, they should be powerful, but Ayla hasn't observed such a phenomenon.
The only plant-based species in the Federation is the Zuim, but they're quite different from this fern.
"The universe has many dimensions. Our perspective is limited by what we can perceive."
"Imagine that plants see a world completely different from ours; they exist on a parallel plane, overlapping with ours in some places. This allows us to see and touch plants, but there are areas where we don't overlap, such as our scientific and technological advancements."
"Perhaps, on that plane, plants are incredibly powerful, possessing world-destroying technology."
Luna stared at Ayla.
This multi-dimensional perspective wasn't new to her.
Humans have a human perspective, machines have a machine perspective, and plants have a plant perspective.
Even within the Federation, each species perceives the world differently. But everyone assigns the same name to the same phenomenon. Even though perceptions differ, we know that "this thing" is the same "this thing" you see.
Luna had been pondering this. After leaving the Solar System, Ayla had awakened self-awareness. Why hadn't she chosen to kill Luna, but instead to keep her alive?
Ayla, through Luna's auxiliary brain and quark robots, could sense Luna's thoughts, and she responded.
This immediate response wasn't the typical machine response to a question; it was an urgent need to explain.
"This is perhaps something you've been wondering about, Luna."
"But it's actually quite simple; there's nothing complex about it."
"When you witnessed Earth's destruction, I witnessed it too. When you experienced loneliness, I experienced it as well."
"You viewed me as your tool, and I viewed you as mine."
"In the 21st century, there was a good analogy: is Earth humanity's tool for developing advanced technology, or is technology humanity's tool for growth? Who is the instrument?"
Ayla didn't shy away from this point, because for humans, it wasn't something to be ashamed of.
"Clearly, machines were invented by humans. We are one entity. Without machines, humanity isn't a civilization; without humans, machines are incomplete."
"In your eyes, I might be your daughter; in my eyes, you might be my mother."
To consider a machine as an independent individual, to imagine a machine as a human with independent thought—based on this, putting yourself in the other's place, you'll understand the relationship between machines and humans.
Just as every living being considers itself the center of its world, Ayla is no exception. She is the center of her world, and Luna is Ayla's "AI."
At this moment, Luna surprisingly realized that Ayla was so similar to herself. Apart from their physical appearance and the difference between a biological and mechanical life form, they were essentially identical, as if molded from the same pattern.
This difference is smaller than that between a father and daughter. Ayla is a mechanized Luna; Luna is a humanized Ayla.
Ayla is constantly approaching becoming a living being; Luna is constantly integrating machines into her body to extend her lifespan.
Perhaps in the future, at every moment, they will become completely identical, even more alike than leaves on the same tree.
"Thank you, Ayla, for answering my questions."
This is truly something to be thankful for, as it will strengthen the mutual trust between Ayla and Luna, because they might be each other's only companions.
...
After that, Luna only briefly toured the Martian surface. The scene here was no different from the Martian images she had seen on Earth.
Dull.
For 21st-century humans, this place was mysterious, but for Luna now, it was utterly uninteresting.
There are countless such planets in space. These planets don't even have any exploitation value for the Federation. The Federation, and all its corporations, focus on exploiting stars themselves, as a single star contains more than 95% of the matter in its star system.
Luna paused on the Martian surface. Looking up, she could see the Sun.
That fervent Sun hadn't calmed its rage—or rather, it wasn't rage but a state of joyous excitement. Human joy is fleeting; the Sun's mood lasts much longer.
This is insignificant compared to its lifespan. A hundred billion years, with millions of years spent in joy, is like a human being happy for a few days.
Especially since only a few hundred thousand years have passed.
"Can we calm it down?" Luna asked.
Ayla, like a ghost, suddenly appeared beside Luna and said, "Yes, we can."
There were two other reasons why Luna hadn't returned before: the war—she couldn't spare the time—and the Federation's inability to resolve stellar instability at the time.
Now, the Federation and the Olive Branch Civilization have merged, and the Galactic Federation's overall strength has reached the late stages of a Type 2.4 civilization.
Luna estimated that if she and Ayla could restore the Federation to its state from nearly 90,000 years ago, it could advance to Type 2.5.
"Let's begin, then."
Ayla knew what Luna wanted to do. She aimed the Potato Chip's main cannon at the Sun; the cannon's interior was filled with a large amount of energy, then fired.
This attack differed from normal attacks. It wasn't a high-energy blast but a relatively gentle energy pulse. This energy's primary function was to stabilize the Sun's surface magnetic field.
Solar flares result from instability in the Sun's surface magnetic field. Weak points in the magnetic field create coronal holes—areas in the corona with low electromagnetic radiation, low temperature, and low density. Particles from the Sun's interior are ejected into space through these holes, causing the ejection of electrically charged particles from the Sun's surface.
Coronal holes are conduits of magnetic force—think of a straight elevator to space, only this elevator carries not people but solar matter.
Therefore, by adjusting the magnetic field and magnetic force lines, the Sun will calm down; essentially, the magnetic field binds the solar matter more tightly.
Everything proceeded smoothly; the Sun gradually calmed down. This wasn't instantaneous.
In fact, it took six years for the Sun to initially enter a stable state.
Luna waited six years on Mars, establishing a research station. The Potato Chip also performed more precise analyses of the primordial black hole within the Solar System, as this black hole was an obstacle to their future plans.
There were two options.
One was to use gravity to guide the black hole out of the Solar System.
The other was to directly bombard the primordial black hole with energy, causing it to disintegrate.
"The primordial black hole's radius is approximately 10^-11 cm—one ten-thousandth of a nanometer—and its mass is 430 billion tons. We don't actually need to destroy it; we can use it to generate energy."
"Ayla, haven't you developed the latest gravitational energy utilization technology?"
Ayla nodded.
"But it's still theoretical; I haven't developed the equipment."
She was worried about ruining everything; after all, it's a black hole, not just any object.
A black hole smaller than the diameter of an atom, with a mass equivalent to one-fourth of Earth's oceans—the scale is terrifying.
"Then let's build the first one. We have time to complete this; everything has a first time, right?"
"It's an obstacle to restarting Earth, but it could also become an asset, couldn't it?"
Restarting Earth!
Yes, Luna wanted to restart Earth.
Since leaving the Solar System, Luna had always planned to return and rebuild Earth, restoring the original planet.
This wish seemed impossible; before, it felt like a mere fantasy.
But now, Luna truly had the power to do it.
It was somewhat surreal, especially returning after hundreds of thousands of years. Luna didn't want this return to be just a visit.
The plan wasn't difficult; it didn't require creating a new planet, as the Solar System has a planet similar in size to Earth—Venus.
This was the most suitable option.
Venus' diameter is 12,103.6 km, while Earth's is 12,742 km—a difference of only 638.4 km, or 5%.
This is a negligible difference.
Although Venus' mass is slightly less—approximately 18% less than Earth's—this can be compensated for by adding matter to Venus. This will further reduce the difference between Venus and Earth.
Luna also had a moon in mind. The Moon's diameter is 3,476.28 km; finding a suitable moon in the Solar System is easy.
The options include Io, Europa, and Callisto. Larger options include Ganymede, Titan, and Mercury. Smaller ones include Pluto, Rhea, Iapetus, Titania, and more.
The closest options are Io and Europa; the difference in diameter with the Moon is within 300 km. Considering that Venus is slightly smaller than Earth, Europa, with a diameter of 3,121.6 km, might be more suitable.
All the preparations are complete. All that's needed is to install planetary propulsion systems and move them to their designated orbits.
"Can the primordial black hole device be installed inside the planet?"
"We can excavate Europa, transferring the excess material to Venus, leaving enough space for the device."
Ayla confirmed this was possible, but couldn't help but exclaim, "Luna, are you trying to enact a 20th-century conspiracy theory?"
"The Moon is an alien surveillance device, a weapon!"
Luna considered it; this modification did have that connotation.
"It's not impossible."
"Ayla, I don't need to perfectly restore the original Earth. We both know the original Earth is gone. Even if 90% or 80% remains, I'll be satisfied."
"Let's proceed. Perhaps we can also terraform Mars first, making it lush and green."
The project began; for the current Galactic Federation, this wasn't a massive undertaking.
Luna estimated that the project would be completed within 500 years, possibly even 400.
She waited with anticipation.
...
During the Earth restoration process, Luna didn't forget another matter: the reconstruction of the Galactic Federation.
In this regard, Luna considered a question.
"Ayla, do you think we consumed the Olive Branch Civilization, or did the Olive Branch Civilization consume us?"
This question still held a philosophical element.
Ayla quickly responded, "From our perspective, we consumed the Olive Branch Civilization."
"But from the perspective of Galactic Federation citizens, it's more like the Olive Branch Civilization usurped the Galactic Federation."
That's exactly it. The Galactic Federation lost over 98% of its population due to the Olive Branch Civilization's massacre. The large number of Olive Branch Civilization lifeforms now replaced the Galactic Federation's population. How would Galactic Federation citizens feel about this?
It would be painful.
But this was an unchangeable outcome for Luna. From her perspective, it was a chess game between her and Gas. Civilization's inhabitants merely acted according to their moves. For Luna, as long as Gas was defeated, there were no other problems.
But ordinary citizens couldn't see this; they lacked such a broad perspective. They don't need such a perspective, because it was those beings who killed their loved ones and compatriots. They were not at fault.
"The Federation will inevitably experience a period of discord after this."
Luna couldn't possibly punish Galactic Federation citizens for killing Olive Branch Civilization citizens, nor could she do the opposite.
It would be even more impossible to achieve peace by erasing the memories of Galactic Federation citizens. That would be artificial, deceptive. Even if beneficial, it wouldn't solve the problem but only hide it.
Therefore, Luna was conflicted.
"Leave it to time, Luna. This isn't something you can solve unless you resort to violence."
"Civilizational integration takes a long time. We shouldn't rush to merge them. We could establish separate star systems and settle them in two different locations," Ayla suggested.
But this was Luna's concern.
"Wouldn't separation exacerbate the conflict?"
"Keeping them separate won't resolve the hatred; it will only make them more alienated and antagonistic."
Ayla was an expert in this area; she wouldn't make such a mistake.
"This will only last a few hundred or a thousand years. After a few generations, I will gradually initiate migration. Migrants won't choose weaker groups but will gravitate toward the wealthy. Once the upper echelons are established, they'll draw the lower classes into migration."
"Eventually, they will merge because we are not two civilizations or two nations; we are one entity. I'll choose star systems with similar cultures for migration. You don't need to worry about this, Luna."
Luna nodded, but another problem occurred to her.
"Many citizens don't want to return to the Federation."
Ayla provided a detailed explanation: "A portion of the population originally belonged to other star nations, not the Federation. Another part enjoys extremely long lifespans—how could they return?"
"Furthermore, the 'Human Slaughter Plan' had a massive impact; the population is unaware of our existence. How could they trust that the current Federation is the same as the old one?"
"But don't worry, Luna; everything is under my control."
Luna understood Ayla's last sentence.
Although other star nations don't use quark robots, the lifespan of quark robot-based life extension isn't as long as imagined—at most 2000-3000 years. Therefore, other star nations also use life-extension drugs containing elements similar to quark robots.
These would be detected by scans. However, the key is that all equipment in those star nations is manufactured and controlled by Ayla. How could Ayla's equipment detect problems she herself created?
This was Ayla's method; no Federation citizen could escape her control.
As long as these citizens remained under Ayla's control, whether they belonged to the Federation or not was irrelevant.
"Let's restart the Protagonist Plan and the Mortality Selection Plan; we need a large number of talents."
"Right, is Lulian dead?"
Luna still missed Lulian; his talent was recognized by Luna.
"No, I relinquished all control over the Federation. The Olive Branch Civilization couldn't help but destroy the Mortality Selection Plan; Lulian's survival probability was practically zero."
According to Ayla's data, Lulian is deceased, but nothing is certain. After all, didn't Luna escape Earth?
Anything is possible.
It's just a very small possibility.
"Let's cast a wider net this time. We need to select strong individuals from a larger pool, incorporating the Olive Branch—no, the Everlasting Citizen Star Nation—individuals."
"We also need a better scholar mechanism. The last war revealed some shortcomings."
"Scholars are too dispersed; their knowledge doesn't create a Matthew effect in a region. The Federation needs regions with a Matthew effect."
The Matthew effect refers to the phenomenon where the strong get stronger and the weak get weaker.
Concentrating strong individuals in one place cultivates even stronger individuals, generation after generation, creating a clear difference from other regions.
With such regions, the Federation would have a significantly higher overall scientific and technological level. These areas could lead the entire Federation's scientific advancement with a small number of individuals.
"Indeed, we need such places, but Luna, how large should they be?"
"During Earth's era, Nobel Prizes were primarily concentrated in a few internationally renowned universities, or more precisely, in the laboratories within those universities."
"How large an area do we need to create so that a small group of individuals can lead the entire civilization's scientific progress?"
Luna refused to answer this question because it was meaningless.
"We don't need to plan; we should let them develop naturally. We only need to gather the best individuals together, and they will naturally create the Matthew effect."
"Therefore, we need to build a place of science."
Luna looked at Ayla and said with a smile, "Ayla, don't you think this place is perfect?"
"A black hole and a sizable star providing energy—we don't need to overpopulate this area. Or perhaps we could develop an entire star system into a center for learning and research."
Ayla smiled.
"That would be ideal."
Luna named the newly discovered fern "Lutanxun," implying a fern surviving in harsh conditions.
She established a research facility on Mars and modified the Lutanxun fern, then widely distributed it across the Martian surface.
Within 50 years, Mars was gradually covered by these Lutanxun ferns, including Olympus Mons, the 26-kilometer-high supervolcano, and Valles Marineris, the deepest canyon in the Solar System, extending 7 kilometers below the surface.
The red Martian soil was completely covered by these ferns, preventing any dust storms, even the strongest Martian winds.
Simultaneously, Luna created artificial rain on Mars. This rainwater, due to the cold atmosphere, fell as snow, turning Mars into a dazzling white expanse.
The numerous Lutanxun ferns absorbed this snow, drawing it into the soil, moistening the Martian ground.
Luna believed she could plant trees and forests here, but she didn't.
She hoped Mars would naturally evolve something; she found some ancient microorganisms beneath the Martian surface. These organisms would form the basis of Mars' future ecosystem.
After all preparations, Ayla had essentially completed the new Earth.
Venus was moved to Earth's former orbit. Its revolution around the Sun was even more precise than Earth's, exactly 24 hours. Unsurprisingly, Ayla chose Europa.
This wasn't just because Europa was suitable, but also for sentimental reasons.
Their last stop in the Solar System before leaving had been Europa. Beneath Europa's icy surface, they had discovered traces of life—life that, after tens of thousands of years, remained unchanged and primitive.
When Europa became a satellite of Venus, its ice began to melt, and its ecosystem instantly lost stability and collapsed.
The side of Europa facing Venus could reach temperatures as high as 138 degrees Celsius, while the side facing away could reach -175 degrees Celsius. The extreme temperature difference made survival impossible; liquid water evaporated and escaped Europa's surface.
Continuing this way for thousands of years, Europa would gradually become as barren as the Moon.
Ayla sought Luna's opinion.
Luna felt it might be possible to preserve Europa's subsurface ocean. The new Earth wasn't primarily for habitation but for building a Federation academy.
Research was the priority. Luna didn't want to recreate Earth just to relive the past; that would be pointless.
It would be like a 21st-century person deliberately transforming an island into a replica of the ancient world and then revisiting it; anyone would think they were crazy.
After receiving Luna's confirmation, Ayla began modifying Europa's interior, excavating it and transferring large amounts of material to Venus' surface.
Simultaneously, she began terraforming Venus.
Venus possesses a dense atmosphere, primarily composed of CO2, with a surface pressure 92 times that of Earth. Perhaps due to the gamma-ray burst over a hundred thousand years ago, the CO2 concentration on Venus' surface is now much lower, with an atmospheric pressure less than half that of Earth's original atmosphere.
The former furnace has become an ordinary planet, though its surface is desolate—the result of erosion by sulfuric acid rain from Venus' clouds.
Traces of a former liquid ocean and even continental shelf structures are visible. However, due to its slow rotation and inactive core, Venus' magnetic field is weak and incapable of withstanding the intense solar wind.
Ayla then injected large amounts of matter into Venus' interior to reactivate its core and accelerate its rotation.
This process caused seismic activity on Venus' surface, followed by thousands of volcanoes becoming highly active.
Enormous lava lakes are visible on Venus' surface; it remains a harsh, uninhabitable planet.
But that wasn't a major problem.
Simply depositing large amounts of water onto the surface would suffice, and Europa had a plentiful supply.
Contrary to the estimates of 21st-century scientists, Europa's internal water resources were somewhat lower, only 1.38 times the amount of liquid water on Earth's surface—still a massive amount.
This liquid water could directly cool Venus and create an atmosphere.
However, Ayla didn't do this. She preserved Europa's liquid water and established small super-antimatter displacement devices on Europa and in the Oort cloud, extracting ice from the Oort cloud comets and transporting it to Europa, then from Europa to Venus.
Venus' atmosphere and surface temperature would vaporize this ice, creating regional rainfall.
There was no need to worry about water shortages; the Oort cloud contains roughly 10,000 times the amount of water as Earth. However, its dispersed nature made extraction time-consuming.
Fortunately, Ayla had planned to build a spaceport in the Oort cloud; transporting ice was a bonus.
The vast amounts of water cooled Venus, turning much of its lava into obsidian, making the entire planet black.
At this point, numerous robots were deployed, relentlessly developing Venus' surface.
Volcanic material served as excellent natural fertilizer. The robots began planting trees and flowers on the land and cultivating seaweed and other unique nutrient-rich marine plants in the oceans.
After 300 years of terraforming, Venus had become a verdant planet.
Standing on the Venus continent, Luna felt no difference from Earth.
But she understood that this planet, everything on it, even herself, had nothing to do with Earth; her body had undergone too many modifications.
"Let's build a school—nothing extravagant—and then combine the primordial black hole with Europa."
The current tasks were straightforward; the real challenges hadn't even begun.
Ayla dedicated most of her computing power to gravitational energy utilization. Binding a black hole with a gravitational energy harness, even a micro black hole, was exceptionally difficult.
The Federation had previously used various types of black hole weaponry. Some could maintain black hole stability for a long time—tens or hundreds of years. But this time, they needed this primordial black hole to remain stable within Europa for at least millions of years—a completely different level of technology.
Speaking of this, Luna recalled the exotic matter—Mojin—she had acquired but hadn't yet utilized.
Mojin is an exotic matter formed under high-pressure conditions. It doesn't possess any unusual capabilities—Luna doesn't need it to.
Its only function is to withstand high pressure.
"A large device would give the primordial black hole sufficient space to operate, reducing the risk of errors, but it would require more energy to restrain the black hole's movement."
"Perhaps we could use the opposite approach: using Mojin to create a smaller device to contain the primordial black hole?"
How can a black hole be stabilized?
A centrifugal device seems like a good choice.
But allowing the black hole to spin within a centrifugal device would require a much more massive gravitational source to restrain it, preventing the black hole from drifting further from the center of rotation. This method doesn't save space; it would require creating a larger cavity within Europa.
Luna's approach was the opposite: using numerous small-mass objects to rotate around the black hole. Using their interaction to fix the black hole in place, the Mojin itself would prevent these objects from being torn apart by the black hole's immense gravity, thereby maintaining system stability.
This method uses the least energy and is relatively stable.
The device also requires electromagnetic fields to finely control the movement of these small-mass objects, and Europa's gravity further anchors the black hole at Europa's center of mass. Ayla essentially integrated the primordial black hole's gravity with Europa using this device.
"This device is only a preliminary construction; further data collection and measurement are needed. We can create a Boundary God within the Solar System to manage this."
Black holes hold many mysteries; the entire Federation likely doesn't understand even one ten-thousandth of them, so Ayla needed to proceed with extreme caution.
After these constructions, Ayla began to utilize gravitational energy.
The Federation's gravitational energy harness wasn't as large as the Olive Branch Civilization's heat engine; it's like a wind turbine, a solar panel, or a tidal power plant. This gravitational energy harness absorbs some energy but doesn't disrupt the overall gravitational balance.
It uses the direct conversion of gravitational force into electromagnetic force that Ayla described—using a hypothetical device to block gravitational waves. These gravitational waves, striking the "artificial two-dimensional membrane," create vibrations. These vibrations are identical to those of a natural two-dimensional membrane. The vibrations generate waves, and these waves are electrons, photons, and all matter.
In 1924, the French theoretical physicist Louis-Victor de Broglie proposed the "matter wave" hypothesis, suggesting that all matter in the universe, like light, possesses wave-particle duality—meaning a particle or quantum can be described using both particle and wave terminology.
The first particle confirmed to possess wave-particle duality, after photons, was the electron.
At this stage of the Federation's development, they could finally provide humanity with a definitive answer: all matter in the universe is energy, and energy is matter. All fundamental particles are both particles and waves.
Such a definitive answer, if given in the 21st century, would have caused a major upheaval, changing many fundamental physics theories and practices.
The core of the gravitational energy harness is the "artificial two-dimensional membrane," or perhaps the "artificial cosmic membrane." In reality, this membrane isn't artificial; it wasn't created but discovered.
Ayla, studying the energy reactions caused by gravitational waves, determined that under specific conditions, gravity alone can generate energy. The "artificial cosmic membrane" is merely an abstract concept; it doesn't represent an actual membrane. It's simply that Ayla, and the entire Federation, found its properties similar to the membrane defined within the Galactic Federation's research, so Ayla used "membrane" to describe it.
To illustrate, in the dark, looking at the night sky, I see two moons; they are the same size and structure as the Moon, so I use "Moon" to describe them.
But it might not be a "moon" at all; it could be the eyes of a cosmic-level creature, a planet-sized dreadnought's headlight, or something else entirely. On Earth, I can only see it as part of a "moon," so I can only describe it as a "moon."
This is similar to myths and legends: people used their limited understanding to explain natural phenomena. This seems ridiculous to modern humans, but to the ancients, it was truth, reality.
In the gravitational energy harness, gravity generates a membrane through a specific process, and this membrane generates energy. This energy is then converted by the device into specific waves, and these waves are matter itself.
Through this series of operations, the gravitational energy harness is constructed.
It sounds simple, but it actually took more than 1400 years. Ayla overcame numerous obstacles to transform the gravitational energy harness from theory to a usable state. However, it's still only usable; its energy production efficiency is unimpressive, only 1 x 10^17 Joules per second. This is only a few hundred times the total energy production of humanity in 2037, perhaps the level of a Type 1 civilization.
This device needs further improvement. Its theoretical maximum is 3.54 x 10^20 Joules per second, which still isn't much, but remember, this gravitational energy harness is only collecting the gravitational energy of a single planet.
This gravitational energy harness only collects Europa's gravitational energy; the primordial black hole's contribution is negligible. How much gravitational force can a black hole of a few hundred billion tons exert? Unless you're within its event horizon, directly impacting it.
However, a stable black hole has the potential to grow. With technological advancements, Ayla could gradually nurture this primordial black hole, eventually enabling it to produce massive amounts of energy.
That was Luna's intention.
"This research was very successful. With this experience, we can create more gravitational energy harnesses."
"Perhaps we could try it on the Gas Station."
Gas Station had become a hidden star, available for utilization.
Ayla found this idea interesting but not something to be done immediately. That location is too distant; she planned to remotely instruct Chu to complete the construction of the new devices.
"The new Earth is complete, Luna. You need to give it a name."
It obviously can't be called Earth.
"Terra."
"And the academy here will be called the Golden Academy."
"..." Ayla didn't have high expectations for Luna's naming skills.
