Time flies like an arrow, and time flies like a shuttle.
2153 years!
A full hundred years have passed since humans returned to the earth, and the human population has reached more than 600 million. With the production of smart medicines, they have gradually spread to everyone. In the past hundred years, technology has been Showing explosive development.
From being able to only transform the earth, humans have now been able to transform entire star systems on a large scale.
The huge smart Dyson sphere has already enveloped the entire sun, and the endless energy it emits is converted into a huge amount of antimatter by the nearby antimatter factory.
At the same time, Venus and Mars have also appeared in the Earth's orbit around the star. In order to move these two big guys smoothly into the Earth's orbit, humans began to study planetary curvature engines in 2070, which cost more than ten years. It took years to create two huge planetary curvature engines, and consumed approximately hundreds of billions of tons of antimatter, equivalent to two years of accumulation on the Dyson sphere, which was only one-tenth complete at the time.
But everything is worth it. The orbit of the earth is the most suitable for human survival. The subsequent transformation of the planet's environment is the least difficult and the time required is also the shortest. In just a few decades, these two originally dead planets, It has become full of vitality, and except for its slightly smaller size, it is no different from the earth.
Moreover, during the construction process, countless technical difficulties were overcome, which also accumulated valuable experience for mankind to build super-large creations in the future.
Before the Dyson Sphere was established, humans once optimistically predicted that at least within a thousand years, humans would no longer worry about energy issues. However, in fact, humans’ energy consumption is growing much faster than humans imagined. faster.
As the saying goes, there is a way of living for the poor, and a way for the rich to live. The poor cannot imagine it. The monthly consumption of the rich is more money than he will be able to earn in his lifetime. This can also describe today's human beings. When energy is extremely large, During the supply period, in order to consume the extra abundant energy every day, all kinds of crazy creations began to be built in large quantities.
For example, the gaseous planet multifunctional mining platform known as the "planetary vacuum cleaner" is extracting gaseous planetary materials from Jupiter.
For example, Planet 4 in the Barnard Galaxy and Planet 5 in the Sirius Galaxy are slowly peeling off rock layers on a rocky planet multi-functional mining platform known as the "Planet Stripper".
Another example is the planetary fortress that stays near the earth and is known as the earth's third "ultimate guardian of mankind" and can fly at a curvature of fifty times the speed of light.
Each of these behemoths has a diameter of hundreds of kilometers, and the energy consumed every second during operation is an astronomical figure, especially the planetary fortress, which is a behemoth with a diameter of 500 kilometers, although it is far larger than the moon. Much smaller, but one and a half times the mass of the moon.
The alloy layer with a thickness of one hundred kilometers and a high degree of collapse, unless it is directly hit by a large-mass antimatter, even if humans use all their strength, they will not be able to break through the defense in a short time. After it is built, it will only be on the surrounding stars. It made several trial voyages in the domain, but in the end it was too wasteful of energy and stayed near the earth.
This is not because the amount of antimatter produced cannot keep up with the consumption of this fortress of confidence, but because in recent years, humans have begun to consciously reserve this strategic resource.
Even today's human beings can't sit back and relax when facing this vast starry sky.
Forty years ago, with the new fourth-generation space detection equipment "Sky Eye" entering service, humans' detection distance of the surrounding area began to penetrate into the surrounding area of 1,500 light-years.
The number of extraterrestrial civilizations discovered has also jumped from three to twelve. The weakest civilizations that can be discovered by space detection equipment are those that can explore the star system where they are located, and there are also interstellar civilizations among them.
Human beings have a strict set of levels of danger to various extraterrestrial civilizations.
The lowest level is the harmless level: this type of civilization, even if it exerts all its strength, cannot harm human beings at all. They can only curl up in the star system and pose no threat to the earth.
This type of civilization accounts for the vast majority of all extraterrestrial civilizations discovered by humans. More than two-thirds of civilizations are mostly at this level.
Secondly, there is the mild threat level: This type of civilization already has a certain degree of danger. They have been able to explore the interstellar space, and some powerful ones have even developed curvature technology. However, there is a huge gap in technological levels. As long as a war breaks out, the winner will be There is no suspense if you lose, such as the Boxing civilization that was destroyed by humans more than a hundred years ago.
The next medium threat level is already a great threat to human beings. This type of civilization is basically at the same level as human beings, and some are stronger. In the event of a war, the outcome is unpredictable.
As for the high threat level and the final destruction level, they are already far stronger than human civilization. Facing such a civilization, the only thing humans can do is to flee far away before the other party reveals its intention to invade.
Fortunately, mankind has not been so unlucky. What mankind discovered this time is a civilization that is moderately close to a high threat level.
It is about 1,200 light-years away from the solar system, and its influence extends to the five surrounding star systems. It looks like a overlord and looks down upon all surrounding civilizations.
Ever since it was detected, humans have been paying continuous attention to this powerful civilization for forty years. In these forty years, the number of technological creations in the main galaxy where it is located has been expanding at a rapid rate. Of course, Not to mention this civilization, the same is true for human beings.
More than a hundred years have passed, and mankind has not been able to forget those years of war. Although the old humans who experienced those years have gradually passed away over the years, the new humans with longer lifespans are still in their prime, and most of them are already in the prime of life. In a leadership position, the sense of crisis is still there.
Since the discovery of this civilization, mankind has immediately entered a state of war.
That huge planetary fortress is the result of this arms race, and there are even two of them still under construction.
In addition, in the past few decades, the number of warp warships built by humans has exceeded 50,000. The density and intensity of the massive space defense construction in the solar system are completely different from those of Bo stars at that time.
Compared with the generally pessimistic atmosphere during the war with the Bosnians, humans have little to fear.
In the past hundred years, human beings have conducted more and more in-depth research on energy quantization, energy quantum jump technology has gradually matured, and human energy weapons have reached the threshold of super-light speed.
The military significance of this cannot be overstated even if it is a transformation.
In the past, humans had no better way to deal with super-light targets except to pile up attack density and rely on luck.
On the one hand, there is no accurate detection system, and the detected spatial fluctuations and specific positions have huge errors. On the other hand, the target speed is too fast and the attack distance is too far.
After all, even if the target detection is accurate, no matter how accurately the quantum computer of the fire control system calculates the position where it can attack the opponent and launches it.
In the hours or even a day or two when the speed of light approaches the target, there are too many variables in between. A weak space fluctuation, the refraction of the thin air in space, and the occasional random change of speed of the target can all make things worse. All preparations are in vain.
But the super-light energy jump weapon has completely changed all this. It greatly ignores the long distance constraints of the attacking party and the interference variables in the journey. The moment it is launched, it can jump to the target in an instant.
In conjunction with humanity's miniaturized space detection equipment and more advanced quantum computers, humanity's hit rate on super-light targets has increased by hundreds of millions of times.
Of course, even if it increases hundreds of millions of times, because the base number is too small, the hit rate of a single attack is still pitifully low.
However, the wars of interstellar civilizations have always involved hundreds of millions of artillery fire. If the number of hits is insufficient, the number of hits can be compensated. Even if the hit rate of a single fort is negligible, under the regional coverage strike, hundreds of millions of energy shells will wash away the ground, even if the target is No matter how fast you go, it's useless.
