The stars, but they become the gray wind

"He clearly had no intention or reason to refuse a technology that could help him and a fundamental facility he had never seen before."

"As long as they agree to let us build a wormhole and stargate network in their galaxy, they can achieve interstellar expansion at a much lower cost. This is a good thing that they have no reason to refuse."

The ring-shaped stargate, accompanied by a neutrino jet, turned from the dark space of the other side of the universe into a vortex-shaped plane like water waves. The second stargate directly connected the Milky Way and the Andromeda Galaxy, built a space-time bridge spanning 200 million light-years, allowing the consciousness of the Avro swarm to travel to the other side of the starry sky 200 million light-years away. In the Andromeda Galaxy, the engineering fleet of the von Neumann self-replicator sent by Sky Star to receive it also began to build superluminal stargates and wormhole networks in one galaxy after another.

“To be honest, I never thought we would return with a large group of space whales.” Nina said as she looked at the hundreds of space whales surrounding the Salem and the fleet led by Fantasy Light.

"Let me correct you. To be more precise, this thing should be called the 'Interstellar Synthetic Biological Mobile Transport Platform'."

"Is the name so difficult to pronounce?"

"Not really. The Avro Swarm has no habit or need for naming things. Whether it's these space whales, the diamond planet, or the Dyson Cloud on the central star of the galaxy, they are all just parts of its body to it. It names them simply to make it easier for us to call them. Before we came, these things basically just had a number, and no so-called official name or title."

"As for those space whales, the starship AI consciousness they carry is essentially a simplified replica of the Avro Hive's main consciousness. Similar to Salem and other strong AIs on Sky Star, they are all simplified and separated parts of the Tree of Life super AI."

"It's just that the functions of each space whale will be differentiated according to actual needs. For example, some specialize in engineering construction, some specialize in space transportation, some specialize in celestial mining, and so on."

"The starship AIs controlling these space whales are essentially subroutines of the Avro Hive with other external hosts and terminals."

"What an interesting group of creatures..." While observing the hundreds of biological starships outside the spaceship that were about to pass through the star gate with her and return to the Milky Way, Nina began to think of new creative inspiration.

…………

In the galaxy at one end of the Milky Way where the House of Celestial Engineering Arts is located, a strange scene appeared. Hundreds of whale-like creatures emerged from the star gate and, accompanied by a rather small fleet of sky stars, headed for a special Dyson cloud component on the central star of the galaxy.

Dozens or even hundreds of space whales, Salem, and the Ultima Thule cruised through the galaxy together. Naturally, such a scene was also recorded by several artists living in the House of Astronomical Engineering Art and turned into a very memorable holographic work.

But these are all stories for the future. The reason why the Avro Swarm wanted to come here was because he also wanted to see what these astronomical engineering artists who received the supernova warning message he sent a million years ago were like. Before the Avro Swarm came into contact with Sky Star, he had no concept of art. Everything he did was just pragmatism based on the actual needs of civilization itself. When he learned from Salem that the people who received the supernova warning message he sent a million years ago were a group of artists, he became curious.

The space whale fleet carrying his subroutine consciousness passed through the star gate and arrived at the other side of the Milky Way in an instant. The first thing he noticed was the ring world orbiting the infrared star 1AU away and the Dyson cloud that blocked almost all light from the star except the equatorial region. However, as the space whale fleet gradually approached the ring world slowly rotating around the star, a row of sky star characters outside the ring world also appeared in the space whale's sensor.

By comparing with the database provided by Salem, he effortlessly translated the meaning of this line of sky star text, and then... the artificial intelligence consciousness of hundreds of space whales froze for a full second.

"Just now... it seemed... it crashed? The reason is... huh??" Salem keenly sensed the connection between him and the space whales. The Avro Hive's subroutine consciousness seemed to have crashed for a second, as if something had shocked it. The red-haired catgirl inquired about the reason, and the answer nearly made Salem lose his composure.

"Poof!" After the communication was temporarily disconnected, Salem couldn't hold it back and laughed with his hands covering his mouth.

"It seems our sisters' abstract art could bring down a hive-mind AI for a full second. Some of our compatriot artists always manage to create works that would blind any intelligent life form."

"Besides, a stellar centrifuge disguised as a ring world is indeed a bit too abstract." Kylias commented sharply on the abstract work of the House of Celestial Engineering Art that could bring down the hive consciousness.

"There are more bizarre celestial projects than you can imagine. Sister Kylias, do you remember how many stellar celestial projects we have now?"

"Counting all those under construction and those already completed, it seems to be in the eight figures, right? Ever since the number of completed stellar celestial projects has been multiplying every few days or months a few years ago, I haven't paid much attention to it."

"To be precise, there are a total of 7,568,407 completed stellar-class astronomical projects within the Milky Way, with 14,671,700 under construction. This does not include the billions of stellar-class astronomical projects in the Large Magellanic Cloud, which are still in the early stages of processing supernovae."

“Has it reached this number without me noticing?”

"Of course, the exponential self-replication of the von Neumann self-replicator is also applicable to the number and growth rate of stellar astronomical projects in a considerable part of the time."

In the solar system on the other side of the universe, after more than two months of assembly, a large space station built by Theia in the lunar orbit was finally completed and put into operation.

The space station consists of two centrifugal wheels with a diameter of 1.5 kilometers that rotate in opposite directions around each other. The two giant centrifugal wheels rotate in opposite directions to balance the structural stability of the entire space station. Each centrifugal wheel is connected to the central axis of the space station by four huge spokes. One end of the central axis of the space station is a huge fuel tank and heat sink, as well as the most important deuterium-helium-3 reactor. At the same time, the entire space station can also obtain energy from the solar sail operating in the lunar orbit as a supplement.

Such a space station was completed in just two months. If a space station of the same size were to be built on Earth, it would take at least several years. While Earth's scientists and engineers are well aware of the technological and energy output gap between them and a quasi-Type II civilization, and can view this terrifyingly rapid pace of space infrastructure development with relative rationality, most people on Earth see only overwhelming reports and media criticism that humanity's current pace and efficiency of space infrastructure development are still too slow. After witnessing the ridiculously rapid pace of space infrastructure development by alien civilizations, Earth's news media has become increasingly filled with the view that humanity's current investment in space exploration and infrastructure development is still too little. Compared to alien civilizations, humanity's pace of space infrastructure development is languishing at a snail's pace. In the context of a world characterized by the abolition of nuclear weapons and large-scale disarmament, human nations should invest more resources in space exploration and infrastructure development. Even if they cannot match the efficiency and technological level of alien civilizations, humanity must not fall behind.

A few days later, the fleet of the Theia civilization officially returned to the Tianda General Six star system 44 light-years away with the recovered and repaired interstellar unmanned exploration ship, leaving only 7 spacecraft for use as resident ships at the lunar surface scientific research station.

That night, the night sky of Earth's northern hemisphere was once again illuminated by the ultra-high-temperature plasma wakes produced by the ignition of the engines of 930 Torch spacecraft. This scene is engraved in the memory of all mankind, constantly reminding us how weak and backward the human species is in the starry sky.

Chapter 218: The Bridge Across Time and Space

The smooth body of the space whale was bathed in the red light of the red dwarf star in the vacuum, just like the countless similar scenes that this space whale community had experienced in the long years since it was created 2000 autobiographical cycles of the mother star. In the time of more than 2000 rotation cycles of the mother star, they almost swam to every red dwarf star within 1000 light years around the mother star system. They had witnessed the birth of stars and the destruction of planets. They even ignited a real star themselves. It was a brown dwarf close to critical mass in a star system nearly 1000 light years away from the mother star system. It revolved around a white dwarf. This space whale community developed a kind of Avro hive consciousness. Unique technology: proton chain fusion reaction rays. The atomic nuclei of all matter hit by these rays will undergo fusion reactions between protons. By manipulating the rays to contact the strong interaction force in the atomic nuclei of matter, all protons contained in the atomic nuclei of the hit matter will overcome the Coulomb barrier under extremely high temperature and pressure to cause a chain of runaway fusion reactions. When such technology is applied to a brown dwarf, the brown dwarf hit by the rays will undergo a runaway chain fusion reaction. The light atoms in the methane and hydrogen that make up the brown dwarf are converted into heavier atoms. The brown dwarf, which originally had too low a mass, under the action of the rays undergoes a runaway chain reaction that would be impossible under natural conditions, allowing the nuclear fusion process of the entire celestial body to continue.

This technology is one of the results of the Avro Swarm's application of the Grand Unified Theory over millions of years. It utilizes and manipulates the four fundamental forces that constitute the material world to a certain extent, and uses artificial means to create some things that do not exist in the natural state. For example, it allows a brown dwarf that is far below the lower limit of stellar mass and is not sufficient to ignite a fusion reaction in its core to undergo a fusion reaction and transform into a real star.

To these space whales, the sun before them was essentially no different from the countless stars in the Andromeda Galaxy. The subprogrammed consciousness of the Avro Hive, distributed throughout the space whales, didn't quite grasp the ritualistic concepts or practices that intelligent beings valued in certain situations. They were simply curious about the location that had received the supernova warning message they had broadcast to all galaxies under their control nearly two million years ago. From their perspective, the Avro Hive observed the entire star system. In their view, the stellar celestial engineering here contained a wealth of strange, redundant, and illogical designs. The small group of Sky Aliens living there seemed to call these strange, redundant, and illogical designs art.

Since its creation, the Avro Hive has never had any similar concepts. Everything it creates is based on pragmatism. Its primary consideration is how to most efficiently utilize the energy and matter of an entire star. For example, it simply cannot understand why the Sky Alien individuals living in this galaxy would add a useless ring of centrifuges with an ecosphere to the Dyson Cloud Project. In its view, since this is a centrifuge device used to harvest entire stars, why add such a large-scale, useless, and cumbersome artificial ecosphere to it?

His curiosity about the Sky Star civilization made him constantly observe around in this galaxy, and at the conscious level he connected to the superluminal interstellar information network built by the Sky Star civilization with the help of wormholes.

In this information network composed of data, He seemed to sense a presence similar to Himself, but that presence did not seem interested in His call. It just conveyed a short message to the Aphro Bee Swarm that had just entered this information network and then left quietly. After He left, the Aphro Bee Swarm read the message sent to it by the other party. The content of the message was some memory fragments of the Tree of Life about the sky stars and the surrounding stars, and the Aphro Bee Swarm kindly explained to the Aphro Bee Swarm the differences and similarities between the two parties.

In addition to the existence similar to itself, the Avro Swarm also felt a lot of existences in this network that seemed to be weakened versions of itself carried by those space whales. These were various Sky Star general strong artificial intelligences separated from the Tree of Life. Like the consciousness carried by the Avro Swarm on the Space Sutra, both were strong artificial intelligence subroutines separated from super artificial intelligence. The Avro Swarm was careful to avoid offending these subroutines active in the network. According to the memory fragments left to it by the Tree of Life, it treated these subroutine artificial intelligences and the Sky Star people who were its own worker bees with great care. In the understanding and concept of the Avro Swarm, the Sky Star people were the worker bees of the Tree of Life, except that these worker bees generally had highly independent self-awareness and decision-making ability, rather than the Avro Swarm, where the entire civilization was a single living giant organism.

On the massive Dyson cloud module used for living, the Sky Star people gazed up at the starry sky, or more accurately, at the swarms of space whales roaming the sky. While both the Sky Stars and the Glass Eels possessed the ability to create these space creatures and bio-spacecraft through synthetic biology, the Space Whales, with their elegant appearance, made it difficult to imagine they were the product of a civilization devoid of artistic concepts. Their design of these space crystals was based solely on pragmatism and efficiency.

"It seems that everyone's understanding of things like stellar astronomical engineering and art is somewhat different, but there are also some similarities." Salem was also observing the reaction of Avro's hive consciousness on the Internet.

"What are the similarities?"

"That's right. Just like the artistic appearance and structure of those space whales you saw, the Avro Hive has no concept of art. When they designed these biological interstellar spacecraft created by synthetic biology, they simply subconsciously felt that apart from practical functions, making these biological spacecraft like this would better align with their ideas. For quite a long time, they themselves didn't quite understand where such ideas came from. They simply subconsciously felt that designing these biological spacecraft like this would better suit their own ideas."

"In short, I subconsciously thought that this would look better. Although there was no concept of art, I still had a similar aesthetic idea."

"That's why I say that both sides have similarities in technology and artistic aesthetics." The red-haired cat girl continued to observe the hive consciousness.

When the Sky Star Fleet returned from the extragalactic galaxy with the Space Whales, the solar system and the Tianda General Six Star System in the other universe also experienced some minor changes.

As the Earth's night sky was illuminated by the torch engines of Theia's massive fleet, all of humanity felt guilty, because they knew that any one of those bright fireballs had the ability to easily destroy and erase their entire planet and their thousands of years of civilization. Humanity must rethink its position in the universe and build a prosperous and unified future based on this.

As the Theia fleet moved away, several small spaceships were also heading from Earth to Mars. The ships were loaded with equipment and tools for surveying and mining asteroids. These would be transported to the Goldilocks asteroid on Mars and used to establish a larger-scale asteroid mining base. After spending a full few months, the complete survey of the Goldilocks asteroid was finally completed, and a large amount of mining and metal refining equipment began to be loaded and shipped to Mars. However, the Earth obviously did not have the efficient torch engine like the Theia civilization, and could only allow the spacecraft to climb the entire distance bit by bit at a very slow speed.

The transport ship, the Unity, had barely crossed one-fifth of the distance between Earth and Mars when Theia's Torch Fleet reached Jupiter's orbit and gradually approached the alien structure anchored in the void—the Stargate. The massive Torch Fleet escorted the massive unmanned exploration vessel encircled at the center of the fleet as they slowly approached the wormhole interface within the Stargate. Finally, the entire Torch Fleet, in a dense formation, passed through the wormhole interface unimpeded and once again entered the familiar slow-space of the wormhole hub. The scenery here remained largely unchanged, except that the AI ​​controlling the Theia fleet and some of the Teyi people noticed that the number of stargates connected to this space seemed to be greater than when they arrived, nearly doubling.

"It seems that the number of wormholes and star gates here has increased?" A Theian observed that the number of star gates at the edge of the space crystal wall was twice as many as when he came here when the fleet passed through this slow space.

"When we came here, there seemed to be more than 16000 seats. Now it has doubled to more than 30,000 seats. Isn't this growth rate too fast?"

"Not bad... For a Kardashev Type III civilization, I'd actually find it strange if it didn't have this kind of efficiency growth rate."

“And does this growth pattern look familiar to you?”

"What looks familiar?"

"It's this exponential self-replication of doubling... When we arrived, there were only about 16000 seats, and by the time we left, it had doubled."

"Doesn't this look like the exponential self-replication of a von Neumann replicator? The reason it doubles is like it just completed a replication cycle."

"It seems to be true..."

"Perhaps the growth pattern of these stargates is similar to that of self-replicating machines, and their number within the Milky Way is exponential, with almost unlimited self-replication and growth."

"Speaking of which, it occurred to me how large the von Neumann self-replicator in our home galaxy has grown."

"I guess we've already reached the 4+4=8 stage. Earlier in the solar system, I heard news from our home planet that the construction of the planetary supercomputing center is proceeding faster than expected."

"The entire planetary supercomputing center is currently about 5% complete. In just ten years or so, that's about five replication cycles."

"It's indeed much faster than expected."

"It is said that our artificial intelligence has made some optimizations to the operating mode and details of the von Neumann machine. Therefore, the construction progress has been greatly accelerated."

.........

Tiandajiangjun is a massive satellite in orbit around the first planet in the six-star system, and a planetary supercomputing center under construction.

In this area, which is equivalent to the size of New Zealand on Earth, countless artificial infrastructure such as automated industrial clusters of displacement technology, giant fusion reactors, radiator arrays, mineral smelting and processing centers, giant supercomputer arrays, etc. cover an area of ​​nearly 30 square kilometers. This celestial body is being slowly transformed into a metal planet covered with artificial buildings, a miniature version of the universe city.

And in the space of planetary orbits, tens of thousands of orbiting solar sails have begun to utilize solar energy. Calculations by Theia's social management AI indicate that within 600 to 700 years, or two generations of Theians, the Dyson Cloud construction will be sufficient to harness approximately 1/400 of a star's energy. By then, Theia will have developed to the power of a Kardashev K1.7 civilization. The completion of a planetary supercomputing center is expected to occur much sooner than that, which is excellent news for Theia, as it means it has already passed the Great Filter, one of the most difficult stages of the transition from Type I to Type II civilization.

Although the future prospects are bright, Theia still needs time to complete all of this. Whether Theia civilization can overcome this bottleneck and the threshold of Type II civilization can only be verified by time.

The space whales that come to the Milky Way are generally not large in size. Even the largest ones are no more than 20 kilometers in length. In this community of space whales that come to the Milky Way, those with a body length of about 15 kilometers, which is just the medium-sized space whales in the standard cognition of the Avro swarm, account for the largest proportion. This ordinary and seldom-visited Sky Star Celestial Art House has recently been visited by many Sky Star spaceships from other star systems. Many Sky Star people come here just to travel in the vacuum with these uniquely shaped biological spaceships.

"I'm a little curious about what their internal structure is like." Anna stood on the back of one of the space whales and stomped her feet lightly.

"Then you'll probably be disappointed. These space whales have no so-called internal structure. Or more accurately, they don't have any passages or compartments like those prepared for physical beings like us. The interiors of these space whales are essentially a vast, airtight network of superconducting carbon computing arrays, serving as quantum computer circuits, just like what we see in their home galaxy, only on a much smaller scale."

"Aside from the supercomputer core, all the remaining space is basically taken up by various devices including cooling, energy, protection systems, and engines. These space whales don't even have a maintenance tunnel inside their bodies, and they don't need one."

"A subatomic-scale von Neumann self-replicator that can easily repair even the slightest damage."

"Although they look like living creatures, don't take them for granted. These space whales are actually quite advanced interstellar spacecraft capable of traveling at near-light speeds."

Anna and Salem were chatting on the back of a space whale docked in a hexagonal honeycomb dock of the Dyson cloud component. For comfort, Anna simply sat on the flat and endless back of this space whale that was more than 15 kilometers long.

"Oh, come to think of it...it's about time these days, right? Something about that."

"The Time Bridge... According to our original calculations, these spacecraft should be returning in the next few days."

"I think it might take some time for us to get used to the idea of ​​ourselves or other people from other points in time constantly traveling back in time."

"Future Carlisle's time travel was essentially just the beginning. It's inevitable that such incidents will become more and more frequent."

"My future self, I'd love to meet him."

In a few days, dozens of spaceships that set out ten years ago, dragging wormholes and moving away at a speed close to the speed of light, will return. The first batch of Sky Star Time Bridge wormholes spanning about ten years will be officially formed today.

Spacecraft traveling at speeds extremely close to the speed of light are invisible until they arrive. Because these ships are traveling at such extreme speeds, the light they emit arrives almost simultaneously with the ships themselves. The Sky Star people, observing the Sky Star system, first observed dozens of ships, seemingly extremely compressed, appearing at the edge of the galaxy. Then, Doppler shift caused the light ahead of the ships to experience a dramatic blueshift, while the light behind them experienced a dramatic redshift. Because of the speed of light in conventional three-dimensional space, the Sky Star people present were actually observing the ships' past positions. This was until the entire ship began to decelerate under the action of its inertia-free engines, and within a distance of several thousand kilometers, its speed rapidly decreased from a speed close to the speed of light, enough to crash into a planet, to a near-zero resting state.

After the spacecraft slowed down from the speed of light to a near standstill, the Sky Aliens present could finally see the star gate and wormhole interface dragged behind the returning spacecraft. It was a real bridge of time that spanned time.

The Time-Like Infinity launched a probe into one of the wormholes. After the probe passed through the wormhole interface, the Time-Like Infinity successfully received information from the past. Kylias, Salem and others felt a sense of joy and happiness coming from the Sky Star people's spiritual perception network.

As a shuttle-shaped spaceship with a very familiar appearance from a time point ten years ago emerged from the wormhole interface, Sky Star broke the boundaries of time and space. The past, present, and future, time will lose its meaning in front of this bridge across time. Sky Star and its related existence will no longer be bound by the law of causality, but become a separate "event" independent of time and space itself that arbitrarily creates paradoxes.

.........

"Elena!" Anna rushed forward and gave a big hug to her sister from ten years ago.

"And... me... Anna." Anna turned her gaze to the person from the past who looked exactly like her and was standing behind Elena.

"I never thought that one day I would be able to look myself face to face." Anna from ten years ago came in front of herself from ten years later. The two held hands and kissed each other on the cheek.

"Even the way of greeting is so familiar, it's worthy of being me." The two Annas said this almost simultaneously.

"I have to say, this feeling is really wonderful." Elena also looked at herself from ten years ago with surprise on her face. The two Elenas who existed as each other's time clones stretched out their fingers and poked each other's cheeks. The real touch made the two Elenas realize that they were not dreaming.

"Also, it seems that we, who have physical bodies, are not the only ones who can experience this kind of time cloning phenomenon?" Anna looked at the two identical artificial intelligence holographic projections in the bridge of the spaceship.

"Rather, isn't it natural that the time bridge formed by the wormhole can be used as a time machine to perform time cloning and create a perfect copy of an object?" Two Xiao Yous who were exactly the same in appearance and behavior said at the same time.

"When we possess superluminal technology and can create closed timelike curves, things like Heisenberg's uncertainty principle will no longer apply to us. A time machine can accurately replicate any object moving on the timeline, including the precise momentum and position of each of its elementary particles at each moment."

"We can even use this method to reset all the elementary particles that make up an object back to its state before a certain moment, achieving an effect that is infinitely close to reversing time."

"And the object whose state of elementary particles is reset can be a broken glass, an entire planet, or even a star system."

"Now, the past and the future are largely meaningless to the current Sky Star civilization."

"Although it is currently impossible to roll back the basic particle composition of matter within the entire galaxy, the current Sky Star civilization will inevitably need time to reach a foundation that can support this scale of world line retracing, but it can still be done on a smaller scale..." Xiao You now took a glass cup from the table and threw it to the ground, smashing it to pieces.

Then, supported by the enormous computing power provided by the Tree of Life, a magical scene began to take place. The shattered glass cup seemed to be flowing backwards in time, and the glass fragments scattered on the ground began to reorganize back to the state before the shattering in front of everyone's eyes. All the elementary particles that made up the glass cup were forced to roll back to the position before the glass cup was broken. The broken glass cup was repaired to its intact state in an effect that was infinitely close to the reversal of time.

"Huh... the burden is a bit heavy." Xiao You breathed a sigh of relief. For the Sky Star civilization, which has a weak foundation now, it is impossible to roll back the particle composition of the entire galaxy. Even the computing power required to repair a glass like this is unimaginable for a general strong artificial intelligence like Xiao You. Therefore, she just relied on the almost unlimited computing power provided by the super artificial intelligence Tree of Life to complete such a seemingly insignificant task as repairing a glass.

"Using the foundation of the Supermatter to the Miracle Age to forcibly apply the technology of the Fantasy Age is indeed a bit of a stretch. At this stage, the Sky Star civilization needs to accumulate for some time. Only after a sufficiently solid foundation is established can it more proficiently control and apply the World Line technology."

Chapter 219 An unexpected little experiment (6000 words)

Communicating with your past self is a rather wonderful thing, especially for the Sky Star people who can perceive each other's emotions and thinking abilities. The person in front of you is obviously yourself from ten years ago. Both of them have the same appearance, memory, and behavioral habits, but they are the same individual from different time periods. This unique time cloning phenomenon makes Elena and everyone else present quite curious.

"Although... having two versions of myself from different time periods is really great, but..." Elena glanced at the two Annas with smirking expressions who were openly trying to tease her and the other sisters present.

"But my sister has become twice as lecherous all of a sudden. It's terrible no matter how I think about it..." Elena held her forehead helplessly.

"As expected of a scoundrel like my sister, she hasn't changed at all in ten years."

The two Annas from different time points who were mercilessly ridiculed by their sister have become bold enough to try to tease Careias and Salem from the time point ten years ago. But as a person with nearly 100,000 years of emotional experience, Careias is a person who deals with Anna's various flirting words skillfully, and can even make the two old Sijianas from different time points blush from time to time. The two Salems and the two Elenas are gloating at Anna who fails to flirt with the girls and is flirted with instead, with a look of suppressed laughter on their faces. Elena, especially, feels an inexplicable pleasure when she sees her two lecherous sisters being humiliated.

After Anna's dark historical scene where she failed to flirt with the girl but ended up being flirted with instead, the atmosphere at the scene became cheerful, and everyone began to happily talk or chat with their past selves. The time cloning phenomenon produced by the wormhole time bridge made this originally impossible thing possible, and also allowed the Sky Star civilization ten years ago to communicate directly with its past selves ten years later.

Moreover, since the wormhole that forms the time bridge is a two-way entrance and exit, not only can the Sky Star of the past come to the present with the help of the time bridge, the Sky Star of the present can also go back to the past through the time bridge. Not only people can go back to the past, but also matter and information. Information and technological products from the future are transmitted to the past. If it were not for the limited capacity of the two-way wormhole that makes up the time bridge, the Sky Star people could even teleport a completed stellar Dyson Cloud celestial project together with the star itself directly back to the past, to the stage where the stellar celestial project has just begun to be built, making the time spent on building a stellar celestial project infinitely close to zero.

Another technological product based on the same principle has already become popular in the Sky Star civilization. That is the macroscopic CTC factory (closed time-like curve). After a product is produced, it will travel through time through a wormhole time bridge leading to a time point tens of minutes ago and be transmitted back to the moment when production just began. Therefore, the factory obtains the completed product at the moment it starts and executes the production procedure. This method can not only obtain nearly infinite production efficiency, but also call on an infinite number of time clones of all raw materials and finished products on the past, present, and future timelines.

With the support of such technologies, the scale of Sky Star's civilization and energy output power in the past decade can no longer be simply expressed by exponential growth. For each individual of Sky Star's civilization, such truly infinite energy, matter and information allow everyone to possess god-like abilities. The House of Celestial Art is a microcosm of the current Sky Star civilization. As long as a Sky Star person needs it, she can shape the stars completely according to her own ideas.

…………

At present, the Theia civilization has launched more than 30 sets of solar sails, but for the construction progress of the entire Dyson Cloud project, solar sails of this scale can only be regarded as a drop in the bucket.

"If you are really bored, why don't you go to the Andromeda Galaxy to supervise the stellar celestial engineering construction and star gate laying work of the entire Andromeda Galaxy?" Hearing the purple-haired girl's complaint, Yuki put down the data terminal.

"That's even more boring. The stellar celestial engineering and stargate construction work over there is entirely handled by the unmanned fleet controlled by the Tree of Life. Forget supervision, they don't even need us to press a button."

"As for the glass eels, they've started a trend of close observation of some of the strange celestial bodies and astronomical phenomena in the Milky Way, but I'm not particularly interested in that."

"So what have you been doing lately? I haven't seen you around much lately...both of them."

"Me? I've been doing a little reverse engineering with my past self from ten years ago."

"Reverse research? What research?" The purple-haired girl suddenly became interested, climbed up from the sofa, and looked at her old friend with shining eyes.
