Fooling Tomoko into being a system

Now that the Trisolaran civilization has discovered that Li Lin is still in the two-dimensional solar system, this place seems very dangerous to them.

The chief scientific officer suggested: "Withdraw Sophon and leave as soon as possible to avoid attracting Li Lin's attention and affecting the first and second Trisolaran fleets."

The chief military officer had a different view and immediately retorted, "Since Li Lin has seen Sophon's behavior at the edge of the two-dimensional solar system with his own eyes and has no intention of attacking, Trisolaran civilization is allowed to conduct research to a certain extent.

If we let this once-in-a-lifetime opportunity pass, who knows how many years it will take before we can come into contact with dimensional technology again? "

The two sides argued endlessly on this issue. The Chief Consul thought about it for a long time, and his heart finally favored the Chief Technology Officer. What is left in the two-dimensional solar system is just a sophon. For the current Trisolaran civilization, the loss can be tolerated. within the range.

The Trisolaran civilization naturally abandoned the topics that had been discussed before the meeting and used neutrino broadcasts to transmit the coordinates of the solar system to the universe.

For a long time, the three-body sophon chose to stay in the two-dimensional solar system, trying to study and master the two-way foil strike data.

Time in the Two-dimensional solar system is still accelerating!

In the 66th year of the Three-Dimensional Cosmic Deterrence Era, Li Lin discovered that an unknown civilization's spaceship had arrived at the destroyed Trisolaran Galaxy. After a moment of pause, it seemed to find a light speed contrail, and then set off towards the solar system!

This light-speed spacecraft made Li Lin lower his head and ponder. Its first target was obviously the Trisolaran Galaxy, and its trajectory followed the light-speed wake left by the Trisolaran First Fleet!

Li Lin initially thought that in the original work, the Gravity launched the coordinates of the Trisolaran galaxy and the Trisolaran civilization was destroyed in only three years. This speed was too fast and there was a time bug.

The Gravity rover uses a huge gravitational wave antenna. The fastest broadcast can only be propagated at the speed of light. The coordinates sent will only be received by people within 3 light years of the Gravity rover.

This means that based on the coordinates of Gravity's position at that time, there is already an unknown civilization spacecraft within 3 light-years away.

Let us now review the positional relationship between the solar system, Gravity, and the Trisolaris galaxy.

The solar system is on the left hand side, and the Trisolaris galaxy is on the right hand side. The distance between them is almost 4.3 light years.

Then there is the very important sophon blind spot, which is where the starship Earth encounters the four-dimensional debris. This position should be between the solar system and the Trisolaran galaxy, about 1.3 light-years away from the solar system. On the lower right, the line connecting the three forms an inverted triangle. .

At this moment, the Gravity rover is exactly 3 light years away from the Trisolaran Galaxy. Combining the gravitational waves emitted with the coordinates of the Trisolaran Galaxy, the Trisolaran Galaxy was destroyed in the past three years.

It can be speculated that the spacecraft of the unknown civilization probably heard the Gravity broadcast near the Trisolaran Galaxy and destroyed the Trisolaran Galaxy.

As for human civilization, it was discovered that the Trisolaran civilization was struck around the 7th year of the Broadcast Era, which coincides with the time when the 4-light-year picture was transmitted from the Trisolaran galaxy to the solar system.

Li Lin took a quick look at the Three-Body Problem for the first time and thought it was a time bug. A distant super civilization used super-light speed to observe, strike and destroy the Three-Body Galaxy.

The original work clearly states that the three-body galaxy was struck by light particles, but we know that the light particle strikes cannot exceed the speed of light.

Therefore, there is a doubt here. Why did the mysterious spacecraft that destroyed the Trisolaran civilization not arrive in the solar system and destroy it around the 7th year of the Broadcast Era?

As long as this alien spacecraft arrives in the solar system, human civilization will discover that the Trisolaran civilization is being attacked and receive the blow at the same time, and there will be no subsequent development of the Trisolaran story.

Another clue can be obtained here, that is, if the Gravity had not transmitted the coordinates of the Trisolaran galaxy to the universe, the Trisolaran civilization would have been targeted by hunters in the dark forest and had already dispatched a light-speed spacecraft to investigate.

At this time, it is no longer important whether the Gravitation Rover launches a broadcast. Even if the water droplets and the Gravity Rover are not captured in the blue space, and the gravitational wave antenna is not used to generate coordinates, the Trisolaran Galaxy still cannot escape the fate of destruction.

Many places in Liu's book that seem to be able to change one's destiny are actually nothing more than a futile struggle.

This is true for human civilization, and so is the Trisolaran civilization.

Back to the question, what caused the mysterious spaceship to arrive in the Trisolaran Galaxy?

Li Lin believes that the Trisolaran civilization conducted a curvature drive engine experiment and left a light speed trail in the universe.

This means that the Trisolaran civilization that masters the curvature drive engine is a dangerous world, and it is normal to send spacecraft for observation.

There are also some speculations about why the mysterious spacecraft did not go to the solar system.

The Trisolaran First Fleet in the original book went straight to the solar system. The First Fleet was not equipped with a curvature drive engine, so it naturally did not leave a light speed trajectory to attract the attention of the mysterious spacecraft.

Then let’s look at the Trisolaran Second Fleet equipped with curvature drive engines.

Thirty-eight days after the deterrence was terminated, the Ringer-Fitzroy Observatory discovered that 38 spacecraft tracks appeared in the interstellar dust clouds near the Trisolaran galaxy and in the direction of the solar system. This should be the first trace of the Trisolaran Second Fleet in 415 years. traces left behind.

When the Trisolaris II was built and only needed one month to travel at the speed of light to reach the Earth, it chose to turn off the light speed engine and use a conventional engine to move forward, which would take an extra year.

The book describes in detail the departure time of the Trisolaran Second Fleet, five years before Cheng Xin became the sword holder.

A simple calculation can be made here. In order to hide its track from being discovered by human civilization, the Trisolaran Second Fleet chose to take a long route. The original distance of 4.3 light-years traveled 5 light-years with a light-speed spacecraft. The remaining 1 year will take It takes a total of 6 years for an ordinary engine to travel to Earth.

It was during this last year that the sophons near the solar system received the coordinates of the Trisolaran system launched by the Gravity a year ago. By this time, the Trisolaran Second Fleet had already concluded that the solar system was unsafe and turned to escape into the universe.

There are several possibilities that the mysterious spacecraft did not go to the solar system.

This spacecraft may be an unmanned intelligent spacecraft. There is no intelligent life on it. Everything is based on program judgment.

There is no need to add an extra person to the Trisolaran Galaxy to check the light speed contrails. Just receiving the launch coordinates of the Gravity is equivalent to confirming that there is a problem in the Trisolaran Galaxy. Ignoring the light speed contrails left by the Trisolaran Second Fleet may be related to the light speed engine experiment of the Trisolaran civilization. Confuse.

It may also be that the intelligent AI completed the original target and discovered that the Trisolaran Galaxy had been destroyed. To a certain extent, it completed the mission and returned directly.

This can be said to be the closest the solar system has come to the gate of hell.

But the reality is completely different. The Trisolaran civilization has obtained the curvature drive engine technology from itself, and will inevitably conduct experiments in the Trisolaran galaxy. Therefore, the light speed contrail appearing near the Trisolaran star also attracts mysterious spacecraft for inspection.
