Ten thousand I am across the heavens

Chapter 663 Searching for Four-Dimensional Fragments
The space highway inside the solar system is a long-term construction project.Not only to build a space highway, but also to build a more three-dimensional structure relative to the ecliptic plane. The solar system is not a plane, the direction that Trisolarans can enter.It is likely to be outside the ecliptic plane. If there is no acceleration ability in this direction, it will undoubtedly be quite dangerous.

And this means that the amount of engineering is much larger. Even if mankind advances the development of science and technology at a high speed and achieves a technological explosion, it is still a super plan that has been planned for a hundred years.

And there are many other plans that also require a huge amount of time, such as exploring deep space. The sooner these plans are implemented, the better. On the one hand, the sooner you start, the farther you can leave the solar system. Observation, on the other hand, is that the Trisolaran universe is in the process of dying. The sooner it starts, the better the state of the universe will be, and the easier it is to observe some special physical phenomena.

This aspect starts with the setting of the three-body world. In fact, even in the world before Lan Nuo traveled, many physicists are still troubled. Why is the speed of light, which represents the highest speed in the vast universe, so slow?
The universe is like a paralyzed patient. It takes millions of years for nerve signals to be transmitted from the head to the feet of the universe. The speed of light is so slow that the distances in the universe become extremely long and the connections become very difficulty.

Before Lan Nuo crossed, scientists did not find the reason. The speed of light seems to have been like that since ancient times, but there is a definite explanation for this phenomenon in the three-body world where Lan Nuo is now.

The universe in the past is not what it is now. The speed of light is very fast, and the vast majority of the world is not three-dimensional, but four-dimensional or even higher.

It's just that with the war between advanced civilizations, the environment of the universe has become more and more harsh, and it has gradually evolved into what it is now.The areas where advanced civilizations once lived are naturally high-dimensional, and in wars, they usually use the rules of the universe as weapons with extremely advanced technology.

Among them, the dimensionality reduction strike is quite convenient, but at that time they did not use a two-way foil, it may be a three-way body, or a dimensionality reduction strike relative to a higher dimension.

After this kind of weapon is used, it is like a hole is pierced in the balloon. The space of the universe will continue to leak towards this gap, and eventually all of it will be transformed into the matter of the low-dimensional universe. High-dimensional creatures, in the process, naturally There is no doubt that death is inevitable, just like human beings entering the two-dimensional plane are also inevitable death.

The race that uses this weapon will transform itself so that it can survive in low dimensions. Although it has paid a huge price, it is possible to use this method to completely wipe out its life and death enemy. It's worth it for a higher civilization.

As a result, such weapons began to be abused. The universe has been reduced from ten dimensions all the way to the current three-dimensional and a few four-dimensional, and this weapon is still being abused.

In the original book, cleaning up the two-way foils used by humans is a manifestation of the abuse of weapons. After the two-way foils are used, the damage caused is constantly expanding. There is almost no way to restore the destroyed time and space to three dimensions, which means that the entire universe is actually It is also gradually becoming two-dimensional.

The speed of light in the universe is also not so low at the beginning. It is also the abuse of certain technologies by intelligent creatures that slows down the speed of light. In fact, it is the light speed spacecraft that is abused. Water can propel a boat, except that soapy water uses the surface tension of water, while the warp drive uses the tension of space-time.

He can make the spacecraft fly at the speed of light, and when accelerating, the crew does not need to be overloaded, but he will cause another kind of destruction.

After the tension of time and space is used, it is difficult to use it again, just like the surface of water that has been smeared with soapy water.Place the same paper boat again.The paper boat will no longer move.

In the area where the light speed engine has worked, the speed of light will slow down slightly. Under the same parameters, there is no way to travel at the speed of light. The more serious it is, the lower and lower the speed of light in that area will be.

This effect can be slowly smoothed out by the surrounding time and space before it reaches a certain level, but this is also equivalent to the damage shared by the entire universe.

The abuse of such devices has made the speed of light in the entire universe lower and lower. After countless years, the speed of light that used to be very fast, the light that used to travel from one end of the universe to the other in a short period of time, has now become 30 kilometers Turtle speed per second.

There is basically no possibility of solving these two problems. It is impossible for civilizations in the universe to stop using light-speed spaceships. Races in a state of war will not give up the use of dimensionality reduction strikes in order to survive. Many times they would rather transform themselves into low-dimensional creatures. , but also use this super weapon to deal the worst blow to the enemy.

But the dimensionality reduction of the universe requires a process, and the dimensionality reduction strikes do not always expand at the speed of light. If human beings explore all directions of the universe, it is very likely to find four-dimensional fragments that have not yet been completely reduced in dimensionality.

And this thing is actually the real purpose of Lan Nuo coming to this world. Although it does not mean that he can understand the four-dimensional mathematical model after reaching the four-dimensional fragment, it will undoubtedly greatly reduce the difficulty of establishing the mathematical model.

This is like building a mathematical model of our nature. When encountering some abstract and incomprehensible problems, we can directly conduct experiments in reality. It is possible to create such a figure in reality, and then directly measure the proportion that the side should occupy. After the proportion is obtained, the possibility is reversed, and the difficulty is greatly reduced.

With the reality to refer to, it has a great advantage in the process of establishing a mathematical model compared to pure speculation. It can shorten the time of a model that may take tens of thousands of years to be calculated by a hundred times.

At the same time, such a space is also very important for human scientific research. In addition to understanding the characteristics of the four-dimensional space first, the sophons and water droplets of Trisolarans will also become very fragile here. Human weapons can easily destroyed.

After all, in such a space, the interior of any structure can be directly reached and touched, the human heart can be directly held, and the fragile structure inside the water droplet can be easily destroyed.

Even if Trisolaran warships appear here, there will still be countless design loopholes. Although they can also obtain the same high-dimensional capabilities, if humans take the lead in adapting to this high-dimensional environment, they will undoubtedly occupy a huge advantage , used to dismantle the Trisolaran's weapon and understand it, it is also a very useful thing.

……

At the Planetary Defense Council, Lan Nuo proposed a plan that surprised everyone: "We can conduct a series of deep space exploration, and at the same time, we can use the huge distance between the long-distance spacecraft to conduct particle acceleration experiments, so that Experiment after experiment. It can also attract sophons to follow, and as time goes by, as the spaceship flies farther and farther, the number of sophons catching up must also increase, otherwise these spaceships may really come from this place. Get the correct data in the process.

At the same time, this does not prevent them from carrying out their mission, which is to explore deep space. The distribution of physical rules in the universe may not be uniform. Even if it is uniform, there may be physical phenomena different from those in the solar system in some places, and even There may be special areas where sophons can't work.

Compared with the vast universe, we are just primitive people who have just walked out of the Great Rift Valley in East Africa. We have only seen savannahs, so we cannot imagine surging rivers, thousands of snow-capped mountains, and vast oceans. And these are undoubtedly meaningful to us.

This plan takes a long time, but it doesn't necessarily mean that there is no return. Compared with the reconnaissance plan, we only need to bring enough fuel this time, and carry enough fuel to accelerate the spacecraft to four times the maximum speed. Then complete the process of parking, reverse acceleration, return and deceleration.

In theory, it is still possible for astronauts to return, depending on whether they are willing to return and how long they can stick to the universe.Individuals in my cluster can participate in this project, participate in the exploration of deep space, and drive the spaceship to fly in any direction outside the solar system at one tenth of the speed of light.

Maybe in the future we can find a livable planet, and the tempter can find a cosmic environment that will decisively change the war between us and the Trisolarans.Of course, this kind of exploration is like finding a needle in a haystack, and it is very likely that we will not get any return on our investment. "

Lan Nuo's proposal this time seems a bit strange. If the previous plans were closely related to people's livelihood and human development, then this time it seems a bit too idealistic and a bit confusing.

If it is just to attract the attention of sophons and make it easier for human accelerators and three-body races to win, then the reconnaissance ship pair can also do the same. It is nothing more than increasing the size and frequency of the reconnaissance fleet. It is not a very acceptable thing for human beings to launch elites into the boundless void.

However, with the construction of the accelerated orbit around the sun, human beings have been able to travel between orbits in the solar system relatively easily. The acquisition of a large number of natural resources and the advancement of technology have made human productivity far from what it used to be. It is not impossible to send a few interstellar exploration spacecraft.

In the past, humans could send Voyagers, and now humans can send some exploration spacecraft, and there is no problem.

However, the exploration direction of the spaceship is also planned, and Lan Nuo will check the technical details in this regard.

The original book described the planet that Natural Selection was going to. Although the Natural Selection was destroyed later, after 200 years, the position of the solar system and the connection between the planet and the planet were calculated, and they were in advance. On that route, there is still theoretical feasibility.

Lan Nuo has made complicated calculations on the orbit, and will correct his own course with a parabolic arc trajectory, and finally enter the same course as the blue space number in the original book, which makes it almost certain that they will encounter The four-dimensional space described in the original book.

And it may not take too long, after all, the era of deterrence has only lasted for 61 years. During these 61 years, the Blue Space has not accelerated to the highest speed, and has retained a considerable part of the fuel to move towards its own goal. driving.

This means that the target area is likely to be less than six light-years away from the solar system, but even if the distance is very close, it is not particularly easy to find him. , His radius is only one-thousandth of a light-year, which is roughly equivalent to hitting a target the size of a water bottle cap from 100 meters away.

And when shooting a target, you can't aim with your eyes. You can only use rough calculations to speculate on the possible positions to blind yourself. As for the probability of hitting, there is indeed, but the probability of missing is even greater.

Therefore, the number of spaceships launched in this direction is significantly more than other directions.

Trisolarans also observed this anomaly, but apart from sending sophons to keep up, they have no clue about this phenomenon. Human thinking is an existence they cannot understand, especially the choice they made before them makes them feel It's ridiculous. Trisolarans have done things like deep space exploration, and even tried many times, but they have never found anything abnormal.

Although they think what Lan Nuo said is very reasonable, whether it is Trisolaran or human beings, they are just new civilizations, and their understanding of the universe is only the tip of the iceberg, but maybe their luck is really bad, and they keep sending out detectors They came to search for habitable planets, but until now they have not found any planets other than the earth that are suitable for them to live in, or areas with special physical rules.

……

Lan Nuo chose a full twenty clones of himself.Joining the deep space exploration team in batches is also a test of the productivity of Trisolarans. If a large number of long-distance spacecraft leave the solar system, and acceleration experiments can be carried out, in the case of a large number of spacecraft leaving at the same time , Whether the Trisolarans can complete the technological blockade of human beings.

At present, people have been able to gradually distinguish the strength of Sophon's blockade of the accelerator, which can be judged intuitively by the difficulty of capturing Sophon.The smaller the proportion of sophons used for interception, the more difficult it is to capture them. Trisolarans usually use a proportion of one-thousandth. This proportion can make it difficult for ordinary human scientists to intercept, but it does not As for being captured by Lan Nuo personally, it caused too much loss.

But if this action really makes the number of sophons insufficient, then the Trisolarans will inevitably split the existing sophons into more shares to intercept human accelerators, which can be directly observed from.
