Decryption —— Human Survival Choice

It is useless to reflect, and the outcome is doomed.

The following is an excerpt from Liu Sanzi's novels except the title.

Past events beyond time (excerpt)

Reflection on the Deterrence Failure of Dark Forest

Of course, the most important factor leading to failure is the swordsman's wrong choice, which will be discussed in another chapter. Here, we will re-examine the mistakes in the design of deterrent system from a technical point of view.

After the failure of deterrence, the first thing people think of is that there are too few gravitational wave transmitters, and it is a mistake to dismantle 20 of the 23 transmitters that have been built. But this idea misses the essence of the problem. According to the monitoring data, the average time for water droplets to penetrate the stratum and destroy a launch pad is only ten seconds. Even if all the planned 100 launch pads are built and deployed, water droplets will not take too long to destroy the whole system. The key is that this system is destructible, and human beings have the opportunity to build an indestructible gravitational wave cosmic broadcasting system.

The problem is not the number of gravitational wave emitters, but the location where they are deployed.

Imagine that if the 23 launch pads that have been built are not on the ground but in space, that is to say, 23 "gravity" spacecraft will be built. Usually, each spacecraft will be separated and scattered in different positions in the solar system. Even if the water droplets launch a sudden attack, it is difficult to destroy them all, and one or more spacecraft will inevitably escape the pursuit and disappear into the depths of space.

In this way, the deterrent degree of the dark forest deterrent system will increase a lot, and the increased deterrent degree has nothing to do with the sword holder. When the three-body world realizes that it is impossible to completely destroy the deterrent system with their power in the solar system, they may be more cautious about their own adventures.

Unfortunately, there is only one "gravity".

There are two reasons for not building many gravitational wave spacecraft: one is the attack of "son of the earth" on the Antarctic gravitational wave launch pad. In this regard, compared with the ground launch pad, the gravitational wave launch spacecraft is more unsafe and has more uncertainties. The second is economic reasons. Due to the huge volume of gravitational wave transmitting antenna, the antenna of gravitational wave spacecraft can only be the hull itself, so the antenna material needs to meet the requirements of aerospace, and the cost is doubled. The cost of building gravity is almost the sum of 23 launch pads on the earth. At the same time, the ship's hull can't be updated, so when the degenerated vibrating string passing through the hull reaches a half-life of 50 years and fails, the launch function of the ship disappears, and a new gravitational wave ship can only be made.

But the deeper reason is hidden in people's consciousness, which has never been said or even realized: the gravitational wave spacecraft is so powerful that its builders are afraid of it. If something happens, the attack of water droplets or other reasons forces the gravitational wave spacecraft to fly deep into space, and because the threat in the solar system can never come back, it will become a new "blue space" and "bronze age", or something more uncertain and terrible. At the same time, they have the ability to broadcast gravitational waves in the universe (although it will not exceed the half-life of vibrating strings), so they control the fate of the human world! In that case, a terrible uncertainty will spread to space forever.

In the final analysis, this fear is the fear of the dark forest deterrence itself, which is the characteristic of the ultimate deterrence: the fear of deterrence is the same as that of the deterred.

.....

With all the dust settled, people's attention shifted from cosmic broadcasting to the review and reflection of the whole event since the end of the deterrence era. Accusations and condemnations against the sword-bearer began to appear in an overwhelming way. If the sword-bearer had started broadcasting to the whole people at the beginning of the incident, at least the subsequent immigration disaster could have been avoided. However, the main focus of public opinion is the choice of the sword holder. This is a very complicated process. The political pressure formed by world public opinion contributed to the final decision of the United Nations and Fleet International at that time. There is a heated debate about who should be responsible, but few people suggest that this is the result of the will of everyone. Public opinion is relatively tolerant of Cheng Xin himself. Her beautiful public image provides some protection for herself. At the same time, her experience as an ordinary immigrant won sympathy, and people regarded her more as a victim. Generally speaking, the sword-bearer's giving up at the last moment made history turn a big turn, but it did not change the whole process. Cosmic broadcasting finally started, so the discussion about that period of history soon subsided, and Cheng Xin gradually faded out of people's sight. After all, the most important thing at this time is to enjoy life.

Excerpt from Immortality after Death: A Plan for Survival

Overall prediction of attacking the dark forest

According to the observation data of the destruction of three-body stars, a mathematical model of catastrophe when the sun is hit by the same blow is established. The calculation of this model shows that if the sun is attacked by light particles, the earth-like planets in the orbit of Mars will be completely destroyed. In the early stage of the attack, Mercury and Venus completely disintegrated, and the earth will retain part of its volume and keep the shape of a sphere, but its surface will be stripped to a depth of about 500 kilometers, including all the crust and part of the mantle; The surface of Mars will peel off about 100 km. In the later stage of impact, all terrestrial planets will reduce their orbits due to the resistance of solar explosive materials, and eventually fall to the remaining core of the sun and be completely destroyed.

The mathematical model shows that the destructive power of solar burst, including the influence of radiation and diffused stellar matter, is inversely proportional to the square of distance, that is, when the distance from the sun increases, the destructive power drops sharply, which makes woody planets far away from the sun survive the blow.

At the beginning of the attack, Jupiter's surface will be seriously disturbed, but its overall structure will remain intact, and Jupiter's satellite system will remain basically unchanged. Saturn, Uranus and Neptune are only generally disturbed on the surface, and their structures remain intact. The diffused solar material will have a certain impact on the orbit of Trifolium, but in the later stage of the attack, the exploded solar material will form a spiral debris nebula, and its rotational angular velocity and direction are the same as those of Trifolium, which will not cause enough resistance to the planet to lower its orbit.

To be sure, the four giant planets of the solar system: Jupiter, Saturn, Uranus and Neptune, are still intact after being hit by the dark forest.

This important prediction is the basis of the bunker plan.

*****

Abandoned human survival plan

Interstellar escape plan:

Technically, it's completely unfeasible. In the planned time period, it is impossible for human beings to have the ability of super-large-scale interstellar navigation, and the number of people who can escape from the stars accounts for less than one thousandth of the total population. It is very unlikely to find habitable extraterrestrial planets before the spacecraft runs out of fuel and the ecosystem fails.

Because the plan can only accept a small part of the population, it violates the most basic values and moral norms of human society, is completely infeasible politically, and may lead to violent turmoil and total collapse of human society.

Long-distance avoidance plan:

The feasibility is very low. The content of the plan is to build human settlements in space far enough away from the sun to avoid solar eruption. According to the model calculation, referring to the protection level of human space city in the foreseeable future, the safe distance is 60 astronomical units from the sun, which has exceeded the Kuiper Belt. The space area at that distance is poor in resources, and it is difficult to find raw materials for building a space city; Similarly, due to the problem of resources, even if the space city is built, human beings will face insurmountable difficulties in its survival.

*****

Three life styles of earth civilization

First of all, the bunker plan

The best choice for success is completely based on the existing technology of human beings, and there is no theoretical unknown. In fact, the bunker plan can be regarded as a natural continuation of human development. Even without the threat of dark forest attack, mankind has reached the era of large-scale migration to the solar system, but the bunker plan is more concentrated and the purpose is more clear.

.....

Take Jupiter, Saturn, Uranus and Neptune as bunkers to avoid the sun explosion caused by the attack of the dark forest. It is planned to build a space city on the back of the four planets for all mankind to immigrate. These space cities are close to the planets, but they are not their satellites, but run around the sun synchronously with the planets, which makes the space cities always on the back of the four planets, and are sheltered and protected by the planets when the sun erupts. It is planned to build 50 space cities, each of which can accommodate about15 million people. One of them is. There are twenty on the back of Jupiter, twenty on the back of Saturn and six on the back of Neptune. There are four on the back of Uranus.

The materials used to build the Space City are taken from the satellites of the four major planets and the rings of Saturn and Neptune.

Second, the black domain plan

Issue a statement of cosmic security by transforming the solar system into a black hole with low light speed. This is the most technically difficult of all options, and it needs to change the basic constants of the universe in a vast space with a radius of 50 astronomical units (about 7.5 billion kilometers). Known as the God Project, there are huge unknowns in theory.

However, once the black domain plan is successful, the security guarantee provided to the earth civilization is the highest among the three options. In addition to the guarantee generated by the cosmic security statement, further research also found that the black domain itself is an efficient defense barrier. A high-speed attacker from the outside, such as a light particle, immediately exceeds the speed of light when entering the low-speed zone. According to the principle of relativity, it can only travel at low speed, and the remaining huge kinetic energy is converted into huge mass. The mass of the attacker entering the low-speed zone first increases sharply, and the speed drops suddenly, while the part still behind the original speed zone will hit the front at high speed, completely destroying the attacker. According to the calculation, even supersolid objects, such as water droplets, which are made of materials with strong interaction, will be completely crushed when passing through the boundary of the black domain. Therefore, people call the black domain cosmic insurance.

There's another advantage of the black domain project. Of the three options, only it can make human beings avoid being displaced in space and live in the familiar earth world for a long time.

However, the earth civilization will pay a huge price for this, and the solar system will be completely isolated from the rest of the universe, which is equivalent to reducing the diameter of the universe where human beings are located from16 billion light years to 50 astronomical units. In the world where the speed of light is 16.7 km/s, what life is like is still unknown, but what is certain is that the electronic computers and quantum computers in that world can only run at a very low speed, and human beings may retreat to a low-tech society, which is a stronger technical lock than naokou. Therefore, in addition to self-isolation, the black domain security statement also has the side of technical self-harm. This means that humans will never be able to fly out of the homemade low-light-speed trap.

Third, the Lightspeed Spacecraft Program.

Curvature-driven technology is unknown in theory, but its implementation difficulty is obviously lower than that of black domain technology.

The speed of light spacecraft can hardly provide any security guarantee for the earth civilization, and this technology can only be used for interstellar escape. This is the most unknown factor among the three options. Even if it is realized, the future of human beings entering the vast outer space will be dangerous and unpredictable. At the same time, due to the danger of escaping from reality, the realization of this plan is full of obstacles and traps in politics. But it is doomed that some people are obsessed with the speed of light spacecraft for reasons other than survival.

It is wise for people in the broadcasting era to carry out three plans at the same time.

Excerpt from Death Eternal Life: The Lightspeed Spacecraft Plans to Die.

Curvature-driven orbit is left when the spacecraft enters the speed of light, just like the burn marks left on the launch pad when the rocket takes off from the ground. After the spacecraft entered the speed of light, it flew inertia, leaving no trace. It can be reasonably speculated that the spacecraft will leave such traces when it enters the sublight speed from the speed of light. I wonder how long the orbit can stay in space. It is speculated that this may be some kind of spatial distortion caused by curvature drive, which may last for a long time or even exist forever.

People have reason to think that Naoko's three-body galaxy looks more dangerous than the solar system from a distance, precisely because the curvature inside the three-body galaxy drives the orbit with a diameter of ten astronomical units-which makes the attack on the dark forest of the three-body galaxy extremely rapid. Orbit and coordinate broadcasting confirm each other, which makes the risk value of three-body galaxies rise sharply.

In the next month, the observation unit 1 found six curvature-driven trajectories in different directions of space, all of which are approximately spherical and vary greatly in size, ranging in diameter from 15 to 200 astronomical units, but all of them are very similar in shape. One of them is only 6000 astronomical units away from the solar system, apparently left by the three-body fleet when it was out of the speed of light. The rest of the ships from their direction and position, has nothing to do with the three-body second fleet. It can be considered that curvature trajectory is ubiquitous in the universe.

This is after the discovery of "blue space" and "gravity" in four-dimensional space debris. Another direct evidence of the existence of a large number of advanced intelligent civilizations in the universe.

One of the tracks is only 1.4 light years away from the sun, which is close to the Oort nebula. Obviously, a spaceship once stayed there. Then he entered the speed of light and left, but no one knew when it happened.

The discovery of curvature-driven trajectory completely killed the already-questioned light-speed spacecraft plan. Both Fleet International and the United Nations have rapidly promoted international legislation, and countries have also enacted laws to completely ban the research and manufacture of curvature-driven spacecraft. This is the most severe legal ban on a technology since the Nuclear Non-Proliferation Treaty three centuries ago.

In this way, there are only two of the three choices faced by human civilization: the bunker plan and the black domain plan.

Past events beyond time (excerpt)

Fear of boundless darkness

On the surface, there are obvious reasons for the death of the light speed spacecraft program: to avoid the curvature-driven orbit exposing the existence of earth civilization in advance, or to improve the dangerous value of the solar system in the eyes of cosmic observers, thus leading to a faster attack on the dark forest. But there are deeper reasons behind this matter.

From the century AD to the end of the crisis era, human beings are full of yearning for the starry sky. But the first step towards the universe is full of failure and pain. The tragic doomsday war made human beings painfully aware of their fragility in the universe, and it was also the dark war between human beings that brought trauma to people's hearts. What happened later, whether it was the trial in the Bronze Age or the hijacking of gravity by blue space and cosmic broadcasting, deepened this trauma and made it rise to the height of philosophy.

In fact, the public is just indifferent to the plan. They think that even if they build a light-speed spaceship in their lifetime, it is not their own thing. The public pays more attention to the bunker plan, which is the most realistic way of life after all; Of course, we are also concerned about the black domain plan. Three centuries of fear have made people yearn for a safe life, and the black domain can provide it. As for being isolated from the universe, people certainly feel sorry, but the solar system itself is large enough, and this regret is acceptable. People pay less attention to the black domain than the bunker plan because ordinary people can also see the super difficulty of this technology. It is generally believed that it is difficult to complete such a divine project by human strength.

Compared with the indifference of the public, the enthusiastic support and resolute opposition of the Lightspeed Spacecraft program come from the elite.

The faction that supports the development of light-speed spacecraft believes that the ultimate security of mankind comes from the expansion and colonization of the Milky Way. In this cold universe, only export-oriented civilization can survive, and the corner of peace will eventually perish. Most people who hold this view are not opposed to the bunker plan, but they all have a strong aversion to the black domain plan and think it is digging their own grave. Although they admit that the black domain can ensure the long-term survival of mankind, for the whole civilization, that kind of life is no different from death.

Most people who oppose the speed of light spacecraft are for political reasons. They believe that human civilization has gone through hardships and finally entered an almost ideal democratic society, and human beings flying to the stars will inevitably have a great social retrogression. Space is like a magnifying glass, which can maximize the dark side of human beings in an instant. Sebastian Snyder, the defendant in the Bronze Age trial, was used as a slogan repeatedly quoted by them:

When humans really live in space, totalitarianism only takes five minutes.

Some people are unwilling to accept the prospect of sowing countless totalitarian seeds from a democratic and civilized earth to the Milky Way.

In infancy, human civilization once opened its doors and looked out. The boundless darkness outside frightened him. Facing the vastness and profundity in the darkness, he shivered and closed the door tightly.

Excerpt from Immortality after Death: The Unsolved Mystery

At this moment. Most of Yunzhi's puzzles have been completed, leaving only one piece: the painting painted by the painter with the eye of a needle.

.....

This metaphor can't be explained in the end, just like Venus's broken arm.

Excerpt from Death and Eternal Life: Escape Velocity

A small piece of paper

That's the only way to describe it Its official name is rectangular membrane, which is 8.5 cm long and 5.2 cm wide. Slightly larger than a credit card, extremely thin and without thickness. Its surface is pure white and looks like a piece of paper.

The members of the expedition are the best professionals and commanders. They all have calm thinking, but the power of intuition is still overwhelming. They are ready for a huge invasion, and some even speculate that it is a ship the size of Europa, which is entirely possible from the strength of gravitational waves it sends out. Looking at this piece of paper from outer space (as they later called it), everyone took a long breath and let go of their long-held hearts. Intellectually, they didn't let their guard down. This thing may also be a weapon, and it may have the power to destroy two ships, but it is really incredible to say that it can destroy the whole galaxy. From the appearance, it is so slender and harmless, like a white feather floating in the night sky. The letter written on paper has long since disappeared, but people have seen it in movies describing the ancient world, so the note is more romantic in their eyes.

*****

As can be seen from the enlarged view of the monitor, the space boat was only a small part of the top, but it soon disappeared completely in that gorgeous plane. The body of the monitor is completely spread out on the plane, showing a huge luminous human figure. However, his body has become a thing without thickness on the plane. Although it is very large, it has only area but no volume.

"We didn't move, and the spacecraft didn't accelerate." "Revelation" pilot said. It is difficult for him to speak when he is overweight.

"What are you talking about? ! "Vasily wanted to shout, but he could only whisper when he was overweight.

From the common sense, the pilot is really talking nonsense. Everyone on the spaceship was pinned down by the acceleration overload, which proved that Revelation was accelerating at high power. It is impossible to judge the motion state of the spacecraft in space by vision, because the reference celestial body is far away and there is no obvious line difference in a short time, but the navigation system of the spacecraft can observe the tiny acceleration and motion of the spacecraft, and this judgment is correct.

The "Revelation" was overloaded but did not accelerate, as if it had been nailed to space by some force.

"In fact, there is acceleration, but the spatial flow direction in this area is opposite, which offsets the acceleration."

Bai Bing said in a weak voice.

"Space flow? Where does it flow? "

"Of course it's there."

Overweight Bai Bing couldn't raise his hand to point, but people all knew the direction he said, and "Enlightenment" fell into a dead silence. Being overweight gives people a sense of security, like escaping from danger in the arms of some protective force, but now it has become a grave of oppression and suffocation.

"Please open the communication channel with the headquarters. There is no time, just consider it our official report." Bai Bing said.

"It's already opened."

"General, you once said that it was nothing, and there was nothing in it. Actually, you are right. There is really nothing, there is nothing in it. It's just a space, just like the empty space around us. The only difference is that it is two-dimensional. Not a piece, but a piece without thickness. "

"Didn't it evaporate?"

"Evaporation is its packaging force field, which separates the two-dimensional space from the surrounding three-dimensional space and is now in contact. Do you remember what' blue space' and' gravity' saw? "

No one answered, but of course they remember that the four-dimensional space fell to the three-dimensional, just like a waterfall flowing down a cliff.

"Just as four dimensions fall into three dimensions, three-dimensional space will fall into two dimensions, from one dimension to microcosmic. The area of that small two-dimensional space-it has only one area-will expand rapidly, which will lead to a greater decline ... We are now in a space that has fallen to two dimensions, and eventually, the entire solar system will fall to two dimensions, that is, the solar system will become a painting with zero thickness. "

"Can you escape?"

"Running away now is like boating on the river near the top of the waterfall. Unless you exceed an escape speed, no matter how you row, you will fall into the waterfall sooner or later, just like throwing a stone on the ground and then throwing it back. The entire solar system is in the falling zone, and escaping from it must reach the escape speed. "

"What is the escape speed?"

"I have calculated it four times, and it should be right."

The people on the "Revelation" and "Alaska" held their breath and listened to the doomsday judgment of all mankind. Bai Bing calmly spoke this judgment:

.....

The "revelation" accelerates to slide to the two-dimensional plane and to the abyss of zero thickness.

"Ladies and gentlemen, don't be depressed. No one in the solar system can escape. Even bacteria and viruses cannot survive. They will all be part of this giant painting. " Bai Bing said that he looks calm now.

"Stop accelerating." Vasily said, "Don't care about this time. Finally, at least let's relax for a while. "

The engine of Revelation stalled, the plasma column at the tail of the spacecraft disappeared, and the spacecraft floated in the silent space. In fact, the spacecraft is still accelerating in the direction of two-dimensional plane, just because it moves with the surrounding space, so people in the spacecraft do not feel the overload caused by acceleration. They are all in weightlessness, breathing comfortably.

Only a small number of people in the book of Revelation know the information about clouds. Now, just for a moment, all these people understand the true meaning of this conspiracy. This is a single metaphor with no meaningful coordinates, because it is too simple and direct. It is possible that Yun Tian Ming thought it was a big risk to add such obvious metaphor to the story, but he took the risk because the information was extremely important.

But he still overestimated people's understanding. He may think that with the discovery of "blue space" and "gravity", people can interpret this metaphor.

The two dark forest attacks that humans have observed do come from light particles, but people ignore the fact that these two galaxies have different structures from the solar system. 187J3X 1 There are four giant woody planets, but their orbital radius is extremely small (observation technology in the first century AD can only find such extrasolar planets), and the average distance between Jupiter and the sun is only 3%, which is even closer than that between Mercury and the sun. A three-body galaxy has only one planet.

Excerpt from Immortality after Death: The Real Way

At this time, there was another scream from inside the spacecraft, which was issued by AA: "Oh, my God! How did Pluto become two? ! "

Cheng Xin turned to the information window, where the photos of Pluto taken by the spacecraft monitoring system were displayed. At this time, Pluto has gone far, but it can be clearly seen that, as AA said, Pluto and its satellite Ka Rong have become two, not far from each other. Cheng Xin also found that not only Pluto was copied, but also the landscape on the two-dimensional plane background was partially copied, just like selecting and copying an area in image processing software and then moving it away slightly.

"That's because the speed of light slows down in the orbit of the ring." Luo Ji explained that his image had begun to distort, but his voice was still clear. "One of the Pluto you see is an image from the slow speed of light. In this process, Pluto is still running, it moves out of the orbit, and sends an image at the normal speed of light, and you will see two. "

"Is the speed of light slowing down?" Cheng Xin is sensitive to a huge secret.

Luo Ji continued: "I heard that you realized the curvature drive from the soap boat. Now I ask: After the boat sailed in the bathtub and reached the other side, did you take it back and put it in the bathtub to try again? "

Not at that time, because he was worried about Naoko, Cheng Xin threw the boat aside, but it was easy to come up with the result.

"The boat won't move any more, because the tension of the water has decreased after the first voyage." Cheng Xin said.

"Exactly, so is the speed of light spacecraft. On the trajectory driven by curvature, the structure of space has also been changed. If the same second curvature-driven spacecraft is placed within the trajectory range of the first spacecraft, it is difficult to move. In track space, a more powerful curvature engine must be used. At this time, the space curvature drive can still make the spacecraft reach the highest speed in orbital space, but this speed is far lower than the highest speed reached during the first voyage. In other words, in the flight path space, the speed of vacuum light is reduced. "

"How much can you reduce?"

"It can be reduced to zero in theory, but it is almost impossible in practice. However, by adjusting the space torque of the' star ring' curvature engine to be large enough, the speed of light in orbital space can be reduced to the mouth-watering 16.7 km per second. "

"This is ..." AA stared at Luo Ji's image and said.

This is the black domain, Cheng Xin thought so, but didn't say it.

"This is the black domain." Luo Ji said, "Of course, a spaceship is not enough to create a black region that can accommodate a star system. According to the calculation, it takes more than 1000 curvature-driven spacecraft to produce a black region that accommodates the solar system. These spaceships accelerate radially to the speed of light in different directions with the sun as the center. Their trajectories are integrated in diffusion to form a sphere covering the whole solar system. The light speed of this sphere is 16.7 km per second, which is a low-speed black hole and a black area. "

"The black domain is produced by the speed of light spacecraft!" AA said.

In the universe, the curvature-driven trajectory can be both a sign of danger and a statement of safety. If the orbit is next to a world, it is the former; If the world is wrapped in it, it is the latter. Like a man with a noose, he is dangerous; But if he puts the noose around his neck, he will be safe.

"Yes, but I know this is very late. In curvature-driven research, experiments are ahead of theory, which is Vader's style, you know. The findings in many experiments cannot be explained in theory. Without the guidance of theory, it is difficult to pay attention to some phenomena consciously. In the early stage of research, that is, in the stage of driving your hair, the wake generated by curvature driving is rarely weak and unnoticed. In fact, there were many signs at that time. For example, after the wake spread, the low speed of light caused the quantum integrated circuits of some computers nearby to fail, but no one thought of it. Later, with the increase of experimental scale, people discovered the secret of curvature-driven wake. It is also for this reason that the federal government agreed to cooperate with us. At this time, it can be said that they are going all out for this cause, and the government has also invested a great deal of power to develop the light-speed spacecraft, but it is too late ... "Luo Ji shook his head and sighed, and did not say more.

"From the ring incident to the completion of the Mercury base, there were thirty-five years, and the precious thirty-five years were delayed." Cheng Xin took the words out for him.

Luo Ji nodded silently. His eyes on Cheng Xin have lost love, just like the torch on the last judgment day, at least in her view. Those eyes clearly said: Son, what did you do?
