West: The psychiatrist on the "Gravity" West
Guan Yifan: the scholar who sailed with the "Gravity" and worked at the cosmological observatory located in the stern;
【Noun】
PDC: Rising Star Defense Board
PIA: The Strategic Intelligence Agency of the Planetary Defense Council, or PIA for short, is an intelligence agency that directly targets the Trimaran Fleet and the home planet; Not far from the United Nations building, this six-story building was built at the end of the 18th century and is thick and strong, like a large block of granite.
IDC: Intelligence Interpretation Committee, a joint body of Fleet International and the United Nations Planetary Defense Council, whose mission is to interpret the intelligence transmitted by Yun Tianming.
"The Past Beyond Time": a memoir of human history written by Cheng Xin;
Crisis Infantilism: Some of the events that took place in human society during the first two decades of the crisis era were difficult for people to understand before and after it, and historians call it crisis infantilism. It is generally believed that infantilism is the result of the sudden arrival of an unprecedented threat to civilization as a whole; This may be true for individuals, but for human society as a whole, things may not be so simple. Typical examples of infantilism are the Face Wall Plan and the Star Project.
Project Stars: The original proposal was to auction the ownership of some stars and their planets outside the solar system under the auspices of the United Nations, with the auction objects to countries, enterprises, social groups and individuals, and the proceeds would be used for the basic research of the United Nations on the common defense system of the solar system. The Stars Project ended at the outset for one simple reason: Stars couldn't be sold. In total, only seventeen stars were sold, all at the reserve price, and the United Nations only earned more than forty million dollars.
Dark Forest Phobia: When humans learned of the dark forest state of the universe, the child who shouted by the campfire immediately extinguished the fire, shivering in the darkness, and even a Mars was afraid. In the first few days, even civilian mobile communications were banned, and most communication base stations around the world were forced to shut down. This measure, which in the past would have certainly triggered great unrest, is now widely understood and endorsed by the population. Although mobile communications have been restored as sanity has gradually recovered, the regulation of electromagnetic emissions has never been stricter, and wireless communications have been limited to a very low power, and emissions beyond this power may be punished with crimes against humanity.
Ladder plan: In order to launch a probe to the three-body fleet, Cheng Xin proposed to use nuclear bombs distributed on the initial short course of the spacecraft, launched there in advance with traditional propulsion, the moment the spacecraft passed through each nuclear bomb, the nuclear bomb exploded behind the sail, generating propulsion, and each explosion of the nuclear bomb increased the speed of the spacecraft by one level, much like climbing a ladder, so it is called a ladder plan.
Human hibernation: The first upright walk in time, all based on the belief that tomorrow will be better. Looking at hibernation technology from a sociological perspective, the hidden dangers of hibernation are real and affect the entire human world. Once this technology is industrialized, some people will go to the paradise of the future, and the rest can only build paradise for them in the gray reality. But most worrisome is one of the biggest temptations of the future: eternal life. With advances in molecular biology and the belief that immortality will surely become a reality in a century or two, then those lucky people who hibernate now step on the first steps of immortality. In this way, for the first time in human history, even death is unfair, and the consequences are really unpredictable.
The Bronze Age: Battleship Survivor of the Dark Campaign, located in space 2,300 astronomical units from the Sun in the Age of Deterrence, has long since crossed the Kuiper Belt, but is still far from the Oort Nebula. Because it was close to the maximum speed, the deceleration consumed a lot of fusion fuel, and finally it could only reach a lower speed in the direction of the solar system, and the voyage home took eleven years.
"Gravity": is the first star-class battleship built on Earth after the Doomsday Campaign, welcoming the return of the "Bronze Age"; At the same time, the entire hull of the "Gravity" is a gravitational wave antenna, which is equivalent to a gravitational wave transmitter that can conduct interstellar navigation.
USS Bronze Age: Captain Neil Scott and six other senior officers sentenced to life imprisonment for crimes against humanity and murder; Of the remaining 1,768, only 138 were acquitted, and the rest were sentenced to prison terms ranging from twenty to three hundred years. The trial was conducted by a military tribunal for the Solar System Fleet, located in a fleet base in geosynchronous orbit. The main body of Fleet International is located in the orbit of Mars, the asteroid belt and Jupiter, but because Earth International is extremely concerned about this case, it has located the court near Earth.
"Blue Space": One of the surviving battleships of the Dark Campaign, "Blue Space" was originally a little more hesitant and skeptical than the "Bronze Age" for the return decoy sent by the Earth of the Deterrent Era, and it only slowed down at low power until it received the "Bronze Age" warning, and maintained a positive speed out of the solar system. After receiving the alert, it immediately switched from decelerating to full-power acceleration and continued to escape the solar system. When Earth learned of this through the Trisolaran's Chiko intelligence, Blue Space became a common enemy of both civilizations.
DX3906: The star that Yun Tianming bought, its planet was discovered by a doctoral student named Ai AA; Located 286.5 light-years from the solar system, the star has one of its greatest advantages: it can be seen.
Femininity: The 80s of the 20th century AD may have been the last era to promote masculinity, and since then, although men are still there, the men liked by society and fashion have become more and more feminine. She remembered some Japanese and Korean male stars at the beginning of the 21st century, who at first glance also looked like beautiful girls, when people called the advent of the male era. The Great Trough interrupted the process of human feminization, but it was accelerated by more than half a century of comfortable peace with the era of deterrence.
Deterrence Gameology: The main elements that make up deterrence are: deterrent and deterred, in the dark forest deterrence are humans and the three-body world, respectively; Deterrence operation, launching three-body world coordinates leading to the destruction of two worlds; Deterrence controllers, people or organizations that master the launch switch; Deterring targets, the three-body world renounces aggression and transmits technology to the human world.
Ultimate deterrence: Deterrence with the consequence of both the deterrent and the deterred is called ultimate deterrence;
Deterrence: Ultimate deterrence is only possible if the deterrence level is higher than 80%. At the beginning of the era of deterrence, the two worlds conducted extremely detailed research on all the personality characteristics of Luo Ji and established corresponding mathematical models, and the deterrence game scholars of humans and the three-body system came to almost the same result: according to the different mental states at the time of deterrence failure, Luo Ji's deterrence degree fluctuated between 91.9% and 98.4%, and the three-body world absolutely did not dare to take this risk.
Sword bearer: The controller of the gravitational wave deterrent system, that is, the sword bearer Dark Forest Deterrent is the sword of Damocles hanging over the head of the two worlds of the earth and the three-body body, and the sword bearer is the hair of the hanging sword, known as the sword bearer; The first sword bearer was Luo Ji, and the second sword bearer was Cheng Xin.
Edge system: During the Cold War, in order to counter the nuclear deterrence of the United States, the Soviet Union created a set of "super doomsday weapons" - "edge system" - in a top-secret state, also known as the "hand of death". In the event of a nuclear war between the United States and the Soviet Union, the activated "edge system" will begin to automatically detect, and if within a certain period of time, it does not receive a response from the Soviet top, it will automatically recognize it as "the end is coming, the Soviet leadership has disappeared", and immediately start a Jedi counterattack against the United States.
World Academy of Sciences: After the establishment of deterrence, in order to receive and digest the scientific and technological information transmitted by the three-body world to the earth, the World Academy of Sciences was established, which is an international organization at the same level as the United Nations. It was initially predicted that humans could only receive sporadic information from the three-body world like toothpaste, and this information was full of deliberate fallacies and misdirections, and earth scientists could only guess at the real new knowledge.
But the attitude of the three-body world in this regard is beyond everyone's expectations, and they have systematically transmitted a huge amount of knowledge and information in a short period of time, mainly basic scientific information, including mathematics, physics, cosmology, molecular biology (based on the life of the three-body world), etc., each category is a complete disciplinary system. This huge amount of information has left the earth science community at a loss.
Cultural reflection: Ten years after the era of deterrence, in addition to massive knowledge and information, there are more and more cultural and artistic works that imitate human beings, including movies, novels, poetry, music, paintings, etc. Surprisingly, the imitation of human culture in the three-body world does not seem to have gone through the process of Handan's toddler, and has reached a very high level at the beginning. This phenomenon is known by scholars as cultural reflection.
In the following decade, the culture of reflection became popular in the human world, replacing the increasingly decadent and lifeless native culture of the earth as the cultural mainstream. Now, a film or novel, without being stated in advance, is generally impossible to see its source, and it is difficult to determine whether its author is human or trisolaran.
A.D. people: People who lived before the three-body crisis, went to the future through hibernation technology, and were called A.D. people by future people.
Cave Age: After the end of the Great Trough Era, cities all over the world went underground, and with the peace that came with deterrence, the second cave age of mankind ended.
Astronomical unit: A unit of astronomy that measures the distance between celestial bodies. Expressed in A.U., its value is taken from the average distance between the Earth and the Sun and converted to 149597870700 meters.
Tomoko: In Three-Body III Death Immortality, the word Tomoko does not refer to those powerful and weird intelligent microscopic particles from the three-body world, but to a woman's name. The woman is a robot, built by humanity's most advanced A.I. and bionic technology, but controlled by intelligent particles formerly known as Tomoko. This woman named Tomoko is the ambassador of the three-body world on Earth, and her appearance makes the communication between the two worlds more natural and smooth compared to the previous low-dimensional unfolding of Tomoko.
Tomoko Blind Zone: At the beginning of the Crisis Era, while using the Chiko system to detect the Earth, the three-body world also launched Tomoko close to the speed of light in other directions of the galaxy, and the first six were launched. But these chikos soon entered the blind zone, and the farthest one flew only 7 light-years. The same thing happened to the Tomoko who was launched later, and the nearest blind spot was encountered by Chiko following Gravity, only 1.3 light-years away from Earth. The quantum connection between chikos is disposable, and once interrupted it is impossible to recover, those chikos who enter the blind zone are lost in space forever. So, until the late Age of Deterrence, the universe remained mysterious about both worlds, but the existence of Tomoko Blind Zone is likely to be indirect evidence of the Dark Forest state, which does not allow the universe to become transparent.
The reservation declares: Tomoko made his first appearance to the world after the suspension of deterrence and announced to the world that the second trisolaran fleet would reach the solar system in four years and would complete the total occupation of this star system. Unlike during the first crisis, the Trisolaran world's policy toward humanity has changed significantly. Tomoko claimed that the three bodies did not have a plan to eliminate human civilization, but set aside reservations for human beings in the solar system, specifically located as: Australia on Earth, one-third of the territory of Mars, so as to ensure the most basic living space of human civilization.
Age of Migration: After the destruction of the gravitational wave broadcasting system, Tomoko announces that humans must immediately begin migrating to the reserved Australia; In order to carry out what she calls "de-threatening" and completely prevent the recurrence of the Dark Forest deterrent and similar threats, humanity must disarm and carry out "naked migration", that is, not to carry any heavy equipment and equipment during the migration process. Immigration must be completed within one year. Migration is led by national governments, and the United Nations Committee on Migration coordinates migration actions around the world. In Australia, migrants are clustered by country and subregion, so that Australia has become a smaller version of the world of the earth, with the exception of large cities, the original place names have been abandoned, replaced by the names of countries and major cities, and now New York, Tokyo and Shanghai are no more than camps of simple houses. The migration in space was completed in three months, with half a million people in lunar orbit returning to Earth into Australia, and one million people in the solar system fleet moving to Mars. At this time, there is no one in the space of the solar system, only empty space cities and warships floating in the orbits of Earth, Mars and Jupiter, floating in the desolate asteroid belt, like a silent metal grave, burying the glory and dreams of mankind. Australia gathers the vast majority of humanity - 4.16 billion people, and outside Australia, there are only about 8 million humans, who are divided into three parts: one million people on the Martian base, five million Earth security forces and about two million Earth resistance members, and a small number of people scattered around for various reasons who have not immigrated, the number cannot be counted.
Excess recovery: After the broken bones grow well, the healed fractures grow thicker than the original, which is called excess recovery in medicine, which means that if the human body has the opportunity to make up for something that was previously missing, then these things may recover to more than people who do not lack them;
Sydney incident: As migrants from all continents flooded into Australia, Australian aboriginal society was boiling with discontent, and the new government began to pursue a tough policy on immigrants, and most of the subsequent immigrants were resettled in the desolate hinterland, and the rich coastal zone like New South Wales was classified as Australia's "reserved territory", and immigration was prohibited, Canberra and Sydney were classified as "reserved cities", and immigration was also prohibited from settlement; Out of the yearning for the city life that has just said goodbye, immigrants flock to Sydney in large numbers, although they are not allowed to settle, but even living on the streets is better than living in migrant villages, at least making people feel that they are still in the civilized world, which makes the city overcrowded. The Australian government's decision to expel migrants from the city of Sydney and to ban immigrants from entering the city in the future caused clashes between migrants stranded in the city and military and police, resulting in some casualties. Hundreds of millions of migrants have poured into New South Wales and flocked to Sydney. Faced with the overwhelming sea of people in front of them, the Australian garrisons of states and cities fled. Tens of millions of people poured into Sydney and ransacked the city, covering a fresh animal carcass like a giant ant colony, quickly turning it into a white skeleton. The city of Sydney is full of fire, crime is rampant, and it has become a terrifying forest made of giant tree buildings, and the living conditions are not as good as the immigration area.
Canberra massacre: The migrant army turned its target to Canberra, more than 200 kilometers away. Since Canberra is the capital of Australia, half of the country's governments moved here after immigration began, and the United Nations has just moved here from Sydney, and the army has had to defend. This time the conflict caused heavy casualties, more than half a million dead, most of them not from the fire of the army, but from the stampede and hunger caused by the chaos of hundreds of millions of people; In this chaos, which lasted more than ten days, tens of millions of people were completely cut off from food and water supplies.
Earth Security Force: It is a human army recruited by Tomoko to oversee the migration of Earth, and she promises that those who join the army will not join the Australian immigration and will be free to live in a world occupied by the Trisolarans. According to later statistics, more than a billion applications for enlistment appeared on the Internet, of which 20 million people participated in interviews, and finally 5 million people were recruited.
Earth Resistance: a movement against Australian migrants, who have many branches and are difficult to count, estimated to be between one and a half million and two million people; Scattered deep in the mountains and underground of the city, they wage guerrilla warfare against the vigilantes and await the final battle against the three-body invaders who set foot on Earth. The composition of the Earth Resistance Movement is complex and includes people from all walks of life, a large proportion of whom are Common Fathers. By the end of the migration, three of the six candidates for the sword-wielding were all commanders of the resistance, leaving only accelerator engineer Bi Yunfeng, physicist Cao Bin, and former vice admiral Antonov.
Gravitational Wave Cosmic Broadcasting System Control Station Zero: The official name of the Dark Forest Deterrent Control Center, the deepest structure ever built by humans, located forty-five kilometers underground, has passed through the earth's crust and deep into the mantle below the Moho discontinuum. The pressure and temperature here are much higher than the earth's crust, and the main component of the formation is solid peridotite. This ultra-deep building is very complex, with an independent closed air circulation system, rather than directly communicating with the ground atmosphere, otherwise, the high atmospheric pressure generated at a depth of forty-five kilometers will cause people to feel serious discomfort; There is also a powerful cooling system to withstand the high temperatures of the mantle of nearly 500°C.
Space Wolf Smoke: Electromagnetic waves as a broadcast medium, due to the high attenuation and high distortion of electromagnetic waves in space, the range of broadcasting is very limited, which is the most primitive means of interstellar communication, known as "space Wolf Smoke".
Embrace anthropocentrism: After the establishment of deterrence, the three-body organization of the earth gradually disappeared, but another kind of extreme organization, which believes in anthropocentrism and advocates the complete elimination of the three-body world, has developed. The "Children of the Earth" is one of the larger ones.
The "dematerialization effect": a concept in aerospace psychology. When people are in the earth world, surrounded by material entities, the subconscious image of the world is material and physical; But in outer space far from the solar system, the stars are only distant points of light, the Milky Way is just a glowing mist, from the senses and psychology, the world has lost its quality and sense of substance, space dominates everything, so the world image in the voyager's subconscious has changed from material to void, and this mental model is the basic coordinates of aerospace psychology.
The syndrome of cosmic three and 300,000: Because the speed of light is known to be 16 billion light years, it is still expanding, but the speed of light is only 300,000 kilometers per second, which is terribly slow. This means that light can never travel from one end of the universe to the other, and since nothing can exceed the speed of light, the information and forces at one end of the universe can never reach the other. If the universe is a person, it means that he does not have a single neural signal that can travel throughout the body, his brain does not know the existence of the limbs, the limbs do not know the existence of the brain, and each limb does not know the existence of other limbs, the universe is just an expanding corpse. Three-dimensional, in string theory, not counting the time dimension, the universe has ten dimensions, but only three dimensions are released to the macro to form our world, and the rest are curled up in the microscopic. String theory has an explanation for this: some people think that it is two types of strings that meet and cancel each other out to release the dimension to the macroscopic, and there is no chance of such encounter in dimensions above three dimensions, which is a far-fetched explanation, in short, it is not mathematically beautiful.
Earth's history: the beginning of a magnificent 3.5 billion years: 2.1 billion years in the Archean, 1.83 billion years in the Proterozoic Aurora Period; Then there is the Paleozoic: Cambrian 70 million years, Ordovician 60 million years, Silurian 40 million years, Devonian 50 million years, Carboniferous 6.5 million years, Permian 55 million years; Then the Mesozoic era began: 35 million years in the Triassic, 58 million years in the Jurassic, 70 million years in the Cretaceous; Then there is the Cenozoic: 64.5 million years in the Tertiary and 2.5 million years in the Quaternary. Then humans appeared, compared with the long years before, with a snap of the fingers, dynasties and times changed like fireworks, and the bone rods thrown into the air by ancient apes turned into spaceships before they fell back to the ground. In these 3.5 billion years, there are 100 billion creatures that have survived through ups and downs.
Infinite details: In the three-dimensional world, human vision is faced with limited details, no matter how complex an environment or thing is, the details presented are limited, as long as you use enough time to watch in turn, you can always see most of the details. But when looking at three-dimensional from four dimensions, because three-dimensional things are exposed to the four-dimensional field of view on all levels, everything that was originally closed and occluded is listed parallel and listed. For example, a closed container can first see the objects inside it, and the interior of these internal objects is also visible, and the juxtaposition of this infinite level of exposure reveals infinite details.
Warping point: The paper of the three-dimensional universe is not flat everywhere, some places are bent, warped to four dimensions, this is the warping point, which is some low-dimensional to high-dimensional passage, from these points into the four-dimensional.
The Lord of the Rings: The Blue Space detected a ring-shaped object with a three-dimensional diameter of about 80 to 100 kilometers, and a ring hoop about 20 kilometers in diameter, like a space magic ring. A circuit-like complex structure can be seen on the ring hoop. From the appearance, it can be basically determined that this object is made by intelligent beings. This is the first time that humans have directly observed a third-party cosmic civilization beyond the two worlds. The Lord of the Rings is closed! It is in four-dimensional space, but it does not show a three-dimensional unfolding, and its interior is completely invisible, which means that it is a four-dimensional object! After entering the four-dimensional space, this is the first time people see a four-dimensional entity.
Rosetta System: is a database developed for the teaching of earth languages in the three-body world, the database contains about two million words of text materials on the natural history of the earth and human history, as well as a large number of moving images and pictures, and is equipped with a software to correspond the text to the corresponding elements in the image to facilitate the interpretation and learning of the earth language.
Dark Forest Strike Features: 1. Casual; 2. Economic.
The so-called arbitrary, that the coordinates are released is the only basis for strike, and there will be no close direct detection of the target, but only a strike, because for super civilizations, close detection is more expensive than strike;
The so-called economic means only the lowest cost strike, using tiny and cheap projectiles to induce destructive energy in the target galaxy.
There is no dark forest between different dimensions, low-dimensional threats do not threaten high-dimensionality, and low-dimensional resources are useless to high-dimensional. But the same dimension is the dark forest.
Security Features/Security Statement: Showing the universe that a civilization is safe and does not pose any threat to other worlds, thereby avoiding the attack of the dark forest; A security statement is essentially a cosmic broadcast, and requires all listeners to believe its content. There is a distant star, a faint point of light in the night sky, and everyone who casually glances at it says that the star is safe, which is the cosmic security statement.
Space Church: A worldwide church in the low Earth orbit of the earth, in fact, it has no physical building, only a huge cross, the two beams of the cross are twenty kilometers and forty kilometers long, can emit light, and its shape can be clearly seen on the ground at night. During worship, congregations levitate under the cross in spacesuits, sometimes numbering in the tens of thousands. Suspended with them, there are countless giant candles that can burn in a vacuum, lit candlelight and shine with the stars, and from the ground, the candlelight and the crowd look like a glowing space dust. Every night, countless people on the ground prayed in front of the cross that appeared in the sea of stars.
Lagrange point: the gravitational equilibrium between the Earth and the Sun;
The combination of the sexes of the three-body person: the way is that the bodies of both sides are integrated, after which the fused body will split, splitting into three to five new young lives, which are their offspring, but these individuals inherit part of the memories of their parents, and have a certain degree of ideological maturity after birth, so they are not real children in the human sense, and the three-body world really has no childhood. Trisolarans and anthropologists agree that this is one of the causes of the great sociocultural differences between the two worlds.
Prediction of the strike time of the dark forest of the solar system:
Optimistic forecasts, one hundred to one hundred and fifty years; General forecast, fifty to eighty years; pessimistic forecasts, ten to thirty years; The Human Survival Plan is planned over a seventy-year period.
Cover Plan: Use the four giant planets Jupiter, Saturn, Uranus, and Neptune as cover to avoid solar eruptions triggered by the strike of the dark forest. It is planned to build space cities for all human immigration on the sunny side of the four planets, which are close to the major planets, but not their moons, but orbiting the sun synchronously with the planets, which makes the space city always on the back side of the four planets, shielded and protected by the planets when the sun erupts. It is planned to build fifty space cities, each with a capacity of about 15 million people. Of these, there are twenty on the back of Jupiter, twenty on the back of Saturn, six on the back of Neptune, and four on the back of Uranus.
Bunker project: Assuming that the survival of human beings in the solar system after the dark forest strikes, the project of building a new world for all mankind, establishing an industrial system for the development of giant planetary belt resources in twenty years, and building a space city in sixty years, with a ten-year overlap period between the two phases.
Cleansing body: Modern washing methods have nothing to do with foam, soap and other washing products disappeared more than a century ago, and now washing mainly uses two methods, ultrasonic and cleaning body. Cleansers are nanorobots that are invisible to the naked eye and can be used dry to clean surfaces and skin in an instant.
Shielding Syndrome: Chiko shielding technology was realized shortly after the end of the Great Emigration, and it is said that the first people to enter the shielding room suffered from a kind of "shielding syndrome", they were as drunk as they were very talkative, and they confided their privacy to those around them without scruples. One journalist put it in poetic terms: "In this narrow paradise, people open their hearts and our gaze is no longer reserved." ”
Space folding: As early as the common century, there were many ambitious space navigation ideas, which envisaged an infinite increase in the curvature of a large area of space, folded in half like a piece of paper, and pasted together two distant points on the "paper" that were tens of millions of light years apart. Strictly speaking, this scheme should not be called space navigation, but should be called "cosmic drag", because it is not essentially sailing to the destination, but dragging the destination by changing the curvature of space.
Curvature drive: For the idea of using space curvature to travel, if a spacecraft in space can iron out part of the space behind it in some way and reduce its curvature, then the spacecraft will be pulled over by the space with greater curvature in front, which is curvature drive.
Two-dimensional metaphor: This model is used to solve the problem of information uncertainty generated by literary language. After completing a double-layer metaphor, attach a single-layer metaphor to fix the meaning of the double-layer metaphor.
Schwarzschild Radius: is the critical radius of any gravitational mass , when the radius of an object is less than the Schwarzschild radius, light cannot escape from the gravitational field within the radius, it becomes a black hole. The formula for Schwarzschild radius is actually derived from the formula for the escape velocity of the object, which sets the escape velocity of the object to the speed of light, and with the gravitational constant and the mass of the celestial body, its Schwarzschild radius can be obtained. If the vacuum speed of light in the solar system drops below 16.7 kilometers per second, light will not be able to escape the gravitational pull of the sun, and the solar system will become a black hole.
Event horizon: The boundary of a black hole is called the event horizon. The matter and radiation outside the black hole can enter the inside of the black hole through the event boundary, and any matter and radiation in the black hole cannot pass through the event horizon, so it is also called the event horizon as a unidirectional membrane. The event horizon is not a material plane, it means that the external observer knows nothing from the physical sense except for the basic parameters such as the total mass and total charge contained in it (referring to the event horizon). The event horizon radius of a spherical black hole is the Schwarzschild radius.
Black domain: People call low-light-speed black holes black domains because compared to the original light-speed black holes, low-light-speed black holes have a large Schwarzschild radius, and the interior is not a space-time singularity, but a vast region.
Cosmic Safe: The Black Domain is an efficient defensive barrier in its own right. High-speed attack bodies from the outside world, such as light particles, immediately exceed the speed of light after entering the low-speed region, and according to the principle of relativity, it can only travel at low speed of light, and the remaining huge kinetic energy is converted into huge mass, the mass of the attacking body first into the low-speed region increases sharply, and the speed drops instantly, and the latter part that is still in the original lightspeed region will hit the front at high speed at the original speed of light, and this effect will completely destroy the attacker. It has been calculated that even ultra-strong objects like water droplets made of materials with strong interaction forces will be completely shattered when passing through the boundaries of the Black Domain. Therefore, people call the Black Domain a cosmic safe.
Asia One: On the back of Jupiter, one of the earliest space cities built by the bunker project, it is a regular cylinder, the centrifugal force generated by rotation simulates gravity, 45 kilometers long, 8 kilometers in diameter, and an internal area of 359 square kilometers, which is about half of the area of Beijing on Earth in the past. At most, more than 20 million people lived here, but now the population has dropped to nine million thanks to the continuous construction of new cities, and it is no longer so crowded...
North America One: Built earlier, Space City, with a radius of 20 kilometers, is the most populous space city, with 20 million people living in it, and is a bustling commercial center in the Jupiter urban community.
Euro IV: The configuration of the city is the most typical ellipsoid, which is characterized by the absence of common artificial suns, and each community has its own miniature fusion suns, which illuminate part of the ground at an altitude of two or three hundred meters. The advantage of this is that the weightlessness axis can be fully utilized, and the tallest or longest building in all space cities has been built on the long axis of Euro 4, which is forty kilometers long and connects the north and south poles of the ellipsoid, forming a long axis in itself. Due to the weightlessness of the interior, it is mainly used as a spaceport and commercial entertainment area. Euro IV is the least populous space city with only 4.5 million people, making it the richest place in the bunker world.
Resource One: With a length of one hundred and twenty kilometers but a diameter of only three kilometers, it is a slender pole, which does not rotate around its long axis, but somersaults with the midpoint as the axis. The interior of this space city is layered, and the gravity of different layers varies greatly, only a few floors are suitable for habitation, and the rest are industrial areas suitable for different gravity.
City Interface: In the later construction of the Uranus and Neptune communities, a number of new space city construction concepts have emerged, the most important of which is the City Interface. In these two communities at the far edge of the solar system, each space city has one or more standard interfaces, which can be docked and combined with each other, and the combined space of urban residents is multiplied, with a better sense of the world, which is of great significance to social and economic development. After the connection, the atmosphere and ecosystem become a whole and the operation state is more stable. The current urban docking method is generally coaxial docking, so that it can rotate coaxially after docking to keep the gravity environment before docking unchanged.
Shelter World: On the sunny side of Jupiter, Saturn, Uranus and Neptune, there are sixty-four large space cities, as well as nearly a hundred medium and small space cities and a large number of space stations, and nine hundred million people live in the bunker world made up of them. This is almost all of the living humanity, and before the Dark Forest strike arrived, the Earth civilization had gone into bunker. The political status of each space city is equivalent to that of a country, and the four urban communities together form the solar system federation, which evolved into the federal government. Historically, the major civilizations of the earth have had a city-state era, and now, the city-state world has reappeared in the outer reaches of the solar system.
Bunker Earth: Became a sparsely populated world, with fewer than five million people living there, people who are reluctant to leave their home planet and fearless about the death that could come at any time. The entire Earth world is currently just an ordinary city-state in the Federation of the Solar System.
Medium space city: refers to space cities with an internal area of less than 200 square kilometers and more than 50 square kilometers, which are generally mixed in the community of large space cities. But the two medium-sized space cities in the Jupiter community, Ring City and Lightspeed Two, are alone in the outermost part of the space city community, far from the main body of the community, almost outside Jupiter's shadow reserve.
Africa II: Space City on Neptune
Indian Ocean One: Space City on Uranus
Circum-Sun accelerator: The diameter of the ring is about 200 meters, and the ring hoop is about 50 meters thick, which is an acceleration coil of the circum-solar accelerator, which has 3,200 coils and a distance of about 1.5 million kilometers, orbiting the Sun in the orbit of Jupiter. The accelerated particles do not run in this ring, but pass through the middle of the ring, are accelerated by the force field generated by the coil, fly to the next coil and are accelerated... It can be done in one or several circles around the sun like this. This is a true super accelerator that accelerates particles to the genesis energy of the Big Bang. It is known as the Great Wall of the Solar System.
Transwarp Group: Cheng Xin's space construction company opened with the money from selling planets, managed by Ai AA;
Interstellar Escape Program: In the planned time period, humans cannot have super-large-scale interstellar voyage capabilities, the number of people who can perform interstellar escape is less than one thousandth of the total population, and the possibility of finding habitable extraterrestrial planets before the spacecraft runs out of fuel and the ecosystem depletes.
Long-range evasion plan: The plan involves establishing human settlements in space far enough from the sun to avoid solar eruptions. According to model calculations, referring to the level of protection of the foreseeable future human space city, the safe distance is sixty astronomical units from the sun, which has crossed the Kuiper belt. The space region at that distance has poor resources and it is difficult to find the raw materials to build a space city; Also due to resource problems, even if the space city is built, human survival in it will face insurmountable difficulties.
Black Domain Project: Issued a cosmic safety statement by transforming the solar system into a low-light-speed black hole. This is the most technically difficult of all options, requiring the transformation of the fundamental constants of the universe in a vast space with a radius of fifty astronomical units (about 7.5 billion kilometers), known as God's Project, and there is a huge unknown in theory.
False alarm incident: The arrival of the false alarm of the arrival of the cosmic strike, the biggest social unrest since the Great Migration, most of the thousands of space launch ports around the world have been forcibly launched from the crowd by shuttles, and more than 10,000 people have died from the flames of nuclear engines. There was also an armed conflict at the base station of the space elevator, and unlike the riots at the launch port, this conflict was between countries, some countries tried to send troops to control the international base station on the equatorial ocean, only to be released in time due to the timely lifting of false alarms did not escalate into war. In Earth's orbit, and even on Mars, there have been crowds vying for spacecraft.
Quasi-interstellar spacecraft: refers to a space vehicle that has an ecological circulation system of an interstellar spacecraft, but is only equipped with an interplanetary propulsion system. Some of these expensive ships under construction belong to large corporations, and some belong to the super-rich. These spacecraft are small, and most of them can only accommodate a few people in the interstellar state, that is, in a state that is completely dependent on the ecological circulation system for long-term survival. They have only one purpose: to hide behind the giant planet for a long time.
Space Outpost: Solar System Early Warning System
Solar System Early Warning System No. 1 Observation Unit: In fact, it is the Ringer-Fitzroe observatory at the end of the crisis era, more than seventy years ago, it was this observatory that first discovered the strong interaction probe water droplets heading towards the solar system, and the observatory is located in space outside the asteroid belt;
Lightspeed II: Once a science city, one of two bases for studying reducing the speed of vacuum light to create the Black Domain, it is now an abandoned empty city
Star Ring City: At the beginning of the bunker project, the research base built by the Transwarp Group, the site of which was chosen at the second Lagrange point at the edge of Jupiter's protected area, was chosen to save the consumption of urban thrusters and position maintenance. Star Ring is the only space science city outside the jurisdiction of the federal government. In the middle of the construction of Star Ring City.
Singer: It is the singer's job to flip through the coordinate data engaged in cleaning work, and it is the fun of the singer to judge the sincerity of the coordinates.
Time Granules:
Cleanup: The singer's job, cleanup is like that, not a precise job, does not require absolute accuracy; It is the work of destroying civilization.
Quality Point: The material that the singer uses to clean up other civilizations
Two-way foil: rectangular membrane, 8.5 cm long and 5.2 cm wide, slightly larger than a credit card, extremely thin, no thickness can be seen, pure white surface, looks like a piece of paper.
Original membrane: also called medium membrane, is the membrane with the lowest communication efficiency, which refers to radio waves;
Starbomber: A person who broadcasts information about the coordinates of civilization
Low entropy body: Earth life form human beings, the name in the eyes of the singer
Big Eyes: Detection matter of advanced intelligence in the universe
Hidden genes: The instinct to hide the coordinates of one's own civilization
Clean up genes: Low entropy bodies have cleaning genes, and cleaning is their instinct;
Slow Fog: The singer's name for the black field of the low-speed region of light
Tomb of Light: Interstellar Earth's term for going at the speed of light
Black Domain: Space City's name for the low-speed zone of light
Revelation/Alaska: Medium spacecraft, two spacecraft in formation, departing from the Neptune urban community to detect unidentified emitter two-way foil.
Star Ring: A small interstellar spacecraft with a maximum crew of four. Most of the space on the spaceship is occupied by the ecological circulation system, and the ecosystem is made into the same four, which are connected and backed up to each other, and if one of them accidentally dies, it can be reactivated by the remaining resources. Another feature of the "Star War" is that it can land directly on a medium-mass solid planet, the "Star Ring" has a fully streamlined shape, and there are many unusual designs on the "Star Ring", for example, the spacecraft has six small courtyards, ranging from 20 to 30 square meters, which can automatically adapt to the direction of gravity when accelerating, and can rotate alone in the spacecraft when sailing at a constant speed, generating artificial gravity. Each courtyard has a different ecological landscape, such as a small green meadow and a stream flowing through the meadow, a grove with a clear spring in the middle, a small beach, and the rise and fall of the clear water with the waves... These landscapes are small and delicate, like a string of pearls dressed with the best things in the Earth world, which is an extremely extravagant design on a small interstellar spaceship.
Two-dimensionalization: into a two-dimensional plane painting without thickness, the accuracy of this drawing is atomic level, every atom in the original three-dimensional world, projected to the corresponding position on the two-dimensional space plane with iron rules. One of the basic principles of drawing this drawing is that there is no overlap, there is no obscured part, and all the details are arranged on the plane and revealed. Here, complexity replaces grandeur. It is not easy to read this drawing, you can see the overall layout of the city, and you can also recognize some macro structures, such as two-dimensional tree buildings still showing tree structure. However, the two-dimensional building structure is so deformed that it is almost impossible to extrapolate the original three-dimensional shape from its two-dimensional graphics by imagination, but there is no doubt that image processing software based on the correct mathematical model should be able to do it. Two-dimensional falls never stop.
Black Domain: A low-speed black hole with a speed of light of 16.7 kilometers per second is the Black Domain, which is produced by light-speed spacecraft. In the universe, curvature-driven tracks can be both a hazard marker and a safety statement. If the track is next to a world, it is the former; If you wrap the world in it, it's the latter. Like a man with a noose in his hand, he is dangerous; But if he puts the noose around his neck, he becomes safe.
Blue Star: DX3906 has one of two planets, another planet with a smaller orbital radius is comparable in size to Earth, and its surface characteristics are very similar to Earth's, with an oxygenated atmosphere, and obvious signs of life, but no traces of the existence of agricultural and industrial civilizations have been found; It appears blue like the Earth, and they call it the Blue Star.
Gray Star: DX3906 star has one of two planets, the one farther away from the star is about the size of Mars, but has no atmosphere, the surface is very desolate, because of its gray color, Cheng Xin and AA call it a gray star
Lightspeed travel: is a milestone, which can be seen as the third enlightenment, the third Renaissance, because the speed of light has fundamentally changed people's thinking, which has changed civilization and culture.
Ultimate Ship: Some people call it the Doomsday Ship. Those light-speed spacecraft have no destination, just drive the curvature engine to the maximum power to accelerate wildly, infinitely close to the speed of light, the purpose is to use relativistic effects across time to reach the end of the universe.
Laws of the Universe: is the most terrible weapon and certainly the most effective means of defense. Whether in the Milky Way or the Andromeda Nebula, whether in the local galaxy group or the super-galaxy group, in the real interstellar war, those participating civilizations with god-like technical power do not hesitate to use the laws of the universe as weapons of war. There are many laws that can be used as weapons, the most commonly used are the space dimension and the speed of light, generally reducing the dimension for attack, reducing the speed of light for defense. Therefore, the dimensional blow to the solar system is the top attack method.
The Pastoral Age of the Universe: The physics and cosmology of the world try to restore the original appearance of the laws of nature before the war, describing the universe that was not changed by the war, which is more than ten billion years ago and is called the pastoral age of the universe. The universe of the pastoral era is not four-dimensional, it is ten-dimensional. The speed of vacuum light at that time was not much higher than it is now, but close to infinity, and light at that time acted at a distance and could travel from one end of the universe to the other in one Planck time.
Dead line: It is a super high-power space curvature spacecraft, which makes the spacecraft reach the speed of light in an instant, and where the curvature spacecraft travels, space is compressed to the extreme. The inside of the dead line can be regarded as zero-dimensional space, without time, everything is dead silent.
Dead line rupture: the state of the dead line will remain as it is if there is no disturbance, that is, it will maintain the diameter of the curvature engine action surface, but when the disturbance appears, it will spread and spread rapidly; Large deadlines can spread to the size of a star system, and scholars call this deadline breakage.
Zeroers: Also called rebooters, it may be a group of intelligent individuals, or it may be a civilization, or several civilizations, and the zeroers want to restart the universe and return to the pastoral era.
Return Movement: A group of intelligent civilizations in the universe who seek to stop the construction of small universes and call for the return of mass from the built small universe to the large universe
Mass loss: The civilized world in the universe, in order to escape the Great Collapse, or for other purposes, create small universes, these small universes are taking away the mass in the large universe.
The regression movement declares that the total mass of our universe will be reduced below the critical value, that the universe will change from closed to open, that the universe will die in eternal expansion, and that all life and memory will die. Please return the mass you took and send only the memory to the new universe.
The Great Universe: In eternal expansion, all galaxies will move away from each other and recede out of their line of sight, when all directions will be dark as seen from any point in the universe. The stars will be extinguished one after another, physical matter will disintegrate into thin nebulae, cold and darkness will rule everything, the universe will become an empty tomb, all civilizations and all memories will be buried in this endless tomb forever, and everything will die forever.
Small universe 647: It has no mass itself, and its mass comes from the matter brought from the large universe. It is the smallest class built in the L three-body world, which carries a total of about half a million tons of material from the large universe, equivalent to the carrying capacity of a large oil tanker in the century AD;
