The last human in the universe

Chapter 154 Environmental Differences
In the face of the extremely high value of the interstellar mines made of this kind of gravity bomb, it is meaningful enough to carry out customized capture plans according to their different defects.

"Secondly... the environment we are in now is not a war environment, nor is it located on the edge of a star.

Interstellar mines are born for the war environment, and their nature requires that they must be extremely concealed and must be integrated into the environment as much as possible.However, we have reason to believe that in the face of ever-changing environments in the universe, such as interstellar dust clouds, the edges of stars, the edges of river galaxies, and inner galaxies, interstellar mines are likely to have different models.

And we can already confirm that these interstellar mines were all placed on the edge of the stars.

If speculation is made based on this point, then, the interstellar mines that were originally customized for the environment at the edge of the stars are far away from any stars at this moment and are in the environment of interstellar space. Will their concealment still be the same as before? "

If a submarine with extremely high concealment is transported to the ground at a depth of thousands of meters in the ocean, it will lose any concealment.

If a warrior who was ambushed in the grassland and made various disguises so that even wild animals couldn't find him, transferred to the desert, he would be as eye-catching as a lamp in the dark night.

Concealment is relative to the environment.This is very simple truth.

But at this moment, the environment of those interstellar mines has changed.

Don't think that the vicinity of the star and the interstellar space where it is at the moment are all space, so the environment will not change.In fact, for advanced civilizations—even for human civilization at the moment, the two environments are very different.

One is most likely to be within the stellar circle, constantly blown by the stellar wind, and the density of matter may be as high as millions of particles per cubic centimeter, while the other has nothing but cosmic high-energy radiation, and the density of matter may be as low as [-] million particles per cubic meter. few particles.

So, can these interstellar mines be found out with the help of the difference in environment?

After listening to Zhao Changxing's analysis, everyone's faces showed deep thought.

What I thought was absolutely impossible to do at the moment seems... not so difficult.

Zhao Changxing changed the subject and continued: "Of course, I am just proposing an overall idea. The specific details need to be studied by experts. But in the final analysis, these gravity bombs are too important to us. The strategic significance cannot be overestimated. We must not let go of this opportunity to enhance our strength! If there is an opportunity, we must take it, and if there is no opportunity to create an opportunity, we must take it!"

It seemed to be infected by Zhao Changxing's emotions. At this moment, facing Zhao Changxing's order, everyone stood up subconsciously: "Yes!"

Different choices mean different fates.But this time, everyone knew in their hearts that because of Zhao Changxing's persistence, human civilization might really have another destiny from now on.

Now that the big principles have been determined, the next details will require many scientists to devote energy and time to solve them.

It is not easy to find this kind of interstellar mine that is suitable for the edge of stars and places with high material density. It is not easy to detect the properties shown in the current interstellar environment.Especially in the fact that people know nothing about the operating principle and design concept of this interstellar mine, it is even more difficult to find this property.

But this is the only place people can take advantage of.

It is foreseeable that the interstellar landmines produced by super civilizations of at least the fourth level of civilization are quite concealed, at least for civilizations of the same level.That is to say, it is not easy to find them one by one in civilizations of the same level, let alone human civilization.

This road is obviously completely blocked, and the only thing that can be used is the change in the environment at this moment.

However, the density changes from high to low, the stellar wind changes from presence to non-existence, and the battlefield environment changes from fierce to peaceful. What kind of characteristics do these changes mean that can be used?
Nobody knows.

Scientists of the original Moyunlitar civilization headed by Viragash and Zhuang Yunwei, as well as scientists of human civilization, have made every effort to explore this issue.

However, after realizing that the current scientific research strength is not enough, Zhao Changxing decisively issued an order to wake up all the scientific workers related to this matter who were in hibernation, and let them all devote themselves to the research on this matter .

As a result, another 10,000+ people woke up from hibernation.

This means a greater consumption of materials and energy, which puts even greater pressure on the limited material reserves of the Yuanhang spacecraft.But Zhao Changxing still chose to do so.

In fact, Zhao Changxing also has a lot of knowledge, and is even qualified to participate in this research.But he put more of his energy on logistical organization and arrangement.

As a civilized leader, he knows very well that his value is not reflected in scientific research.

In the face of this kind of thing, no matter how smart or excellent a person is, it is only one person's strength.Doing these logistical and organizational tasks well can enable hundreds of thousands of scientific researchers to exert greater strength.

Time slipped away under such circumstances.

Scientists first proposed the first option.

This scheme is very simple and crude.Scientists plan to divide the sphere with a radius of 4.19 million kilometers and a total volume of about 4.19 billion cubic kilometers into [-] million cubes with a volume of [-] million cubic kilometers. The core of each block, by creating a super-strong light source, enables those interstellar mines hidden in the dark to have enough reflected light, so that they can be found.

After realizing that the materials and time required for this plan were too long to be of practical significance, people further modified the plan, adjusted visible light to other forms of electromagnetic waves, and greatly expanded the volume of a single block.This reduces the number of blocks to search to about 4000 million.

But this is still not of practical significance.At the same time, this has also reached the accuracy limit predicted in the theory and cannot be expanded any further.

So this plan was abandoned.

After this, a second plan was proposed.

The idea of ​​this plan is to still use the Yuanhang spacecraft as the center of the sphere, and then set up a spherical mask with a radius of [-] million kilometers. Assuming that the mask emits light uniformly everywhere, then any one that exists in this sphere Objects will definitely cast their own shadows on the center of the sphere of the Yuanhang spacecraft.

At that time, by measuring these "shadows", it will be possible to determine in which direction of the Yuanvoy spacecraft there are objects.Then by making further observations in that direction, the distance can be determined.

This scheme seems to be feasible in theory.The main problem is how to build a large enough spherical mask with a surface area of ​​12.6 billion square kilometers to cover the spherical space with a radius of [-] million kilometers.

It is obviously unrealistic to actually build a mask with such a huge area, and it has no operational significance.But through some special methods, it seems that a similar effect can be achieved.

For example, projection technology and so on.

But after further analysis, projection technology was also denied.Human civilization at this moment does not have such a level of technological strength.

After that, another group of scientists proposed another idea based on this plan.That is to say, there is no need to manually set up the spherical mask, but to use the natural environment to achieve the effect similar to the spherical mask.

cosmic microwave background radiation.

It is a natural "mask" so huge that it occupies the entire universe.

The cosmic microwave background radiation exhibits a high degree of isotropic radiation intensity.That is to say, if the Yuanhang spacecraft is the center of the sphere, no matter which direction the observation is made in all directions, the observed radiation intensity should be consistent—of course, after removing the influence and interference caused by one’s own movement and various stars .

Then, theoretically speaking, after removing the interference of one’s own movement and various stars—because these objects are definite and can be accurately observed, so their influence can be accurately removed—the observed universe The difference in the microwave background radiation is most likely caused by the tiny objects that exist near the Yuanhang spacecraft.

At that time, through this difference, the coordinates of those objects can be roughly located.

The specific implementation process will of course be hundreds of millions of times more complicated than this. In actual operation, people also need to consider factors such as distance, but the basic principle is probably like this.

Then, the only thing that needs to be solved now is the problem of observation accuracy.

Is human civilization capable, with the current level of technology, to manufacture observation equipment with sufficient precision to observe the differences in the cosmic microwave background radiation caused by those objects?
After further calculations, people came to a very definite answer.

No.

The conclusion is that there is a huge order of magnitude difference between the precision required to execute such a scheme and the precision available to human civilization at this moment.

I'm afraid, even if the super civilization that is at least level [-] comes in person, it won't be able to have such precision.

This plan was also declared bankrupt.

Until all scientific researchers related to human civilization were awakened, and hundreds of thousands of scientists researched, discussed, experimented, and guessed for more than a year, another new plan was proposed.

In the main control room of the Yuanhang spacecraft, Zhuang Yunwei reported to Zhao Changxinghui with a little hoarseness: "We can only say that if the shell materials of those gravity bombs are similar to those of their spacecraft, then this method, possibly, may be Effective."
