In the case of convenient stellar coordinates and stars as a source of energy to support high-power communication,

There seemed to be a possibility of communication between the pioneer astronauts.

It is precisely because of this possibility that Yang Meng remembers that in that meeting,

Some people continue to propose that after the pioneer astronauts reach the target star, they hope to obtain communication rights with other pioneer astronauts.

However, after a simple calculation by the researchers at the conference.

Such a proposal was also rejected to a certain extent,

As for the reasons for refusal......

Even using stars as coordinates to communicate is not an easy task.

It also happened that the researchers at the meeting,

Let's take Rutan and Ross 128 as examples.

Although the distance between Ross 128 and the solar system is 10.9 light-years, the distance between Rutan and the solar system is 12.36 light-years.

The straight-line distance between the two stars appears to be 1.46 light-years.

But in fact, both stars are in a constantly moving cosmic space.

The Sun, Rutan, and Ross 128 stars are not in a straight line,

At that time, researchers were worried that some pioneer astronauts would not be able to understand professional astrophysics.

I used the simple trigonometric cosine theorem in middle school to make simple calculations.

If you connect three stars to each other, you can form a triangle.

Suppose that in this triangle,

The angle of the apex where the sun is located is 45 degrees,

Rutan's side with the Sun is 12.36 light-years,

Ross 128 is 10.9 light-years away from the side of the solar system.

With these data, we can roughly estimate the distance between Rutan's star and the Ross 128 galaxy according to the cosine theorem in secondary school mathematics.

After calculation,

When using the solar system as a reference frame, the distance between Rutan and Ross 128 looks very close.

But the actual distance is more than 10 light years.

It is still difficult to communicate with the communication devices carried by the two spacecraft over such a long distance.

In terms of spatial position, the Rutan star and the Ross 128 galaxy are still close to the orbital plane of the solar system.

The location of other galaxies is more complicated.

Some stars are in the upper part of the solar system, such as Tianjin, which is 11.4 light-years away, and it is 29a and b

Some stars are below the solar system's sun, such as Sirius A and his white dwarf b, which are 8.6 light-years away

The stars that the pioneer astronauts traveled to can be said to be in all directions of the solar system.

If these stars want to communicate with Rutan,

Most of them are more than 10 light-years away.

For each light-year increase in the communication distance, the energy required to ensure the accuracy of the communication signal also increases exponentially.

Therefore, under non-essential conditions,

Even if an astronaut reaches the target system, there will be no communication between other pioneer astronauts, and it will not be necessary.

Of course, that meeting took into account the actual situation,

In extreme cases,

They can communicate with nearby stars, and as for what the extreme situation is, it is left to their pioneer astronauts to judge for themselves.

"Unfortunately, the closest to the Ross 128 galaxy is Wolf 359, 7.8 light-years from Earth.

It's not me here,

And the closest to me is the extremely dangerous Nanhesan! There were no pioneer astronauts there! ”

"Ross 128 is still very far away from me in terms of time and space distance......

Yang Meng muttered to himself,

Although he was very worried about the situation in the Ross 128 system,

But more of a helplessness to not be able to help,

This helplessness requires them to passively accept from the first day they become pioneer astronauts.

Accept watching your teammates fall for the sake of human pioneers.

……

It took a long time for Yang Meng to calm down his mood,

And the calming mood is because his crisis has not been completely lifted at the moment,

He needs to gather enough resources and perfect his ship to leave the system.

Otherwise, he would probably be like the Rutans,

Even if it advances by leaps and bounds in information technology and reaches a height that mankind has never reached before, it is still stuck on a planet.

In a long period of time, resources will always run out,

In the end, the result can only be extinction,

Yang Meng didn't want to be trapped in such a dark red galaxy, he wanted to go back to Earth.

Under the suppression of this thought,

The matter about the Ross 128 galaxy has finally been turned over,

Yang Meng focused his attention on the information that followed.

"I didn't expect to accumulate so much information!"

However, Yang Meng browsed the information content behind, but inexplicably produced a sense of separation.

Because some of the latter information made him feel inexplicable,

For example, what happened in some of the news seems to appear out of thin air without cause and effect.

"Why is this happening?"

This sense of fragmentation of information fracture made him very uncomfortable.

And when he saw the time on the message, he instantly understood the source of this feeling:

Because in the moments before the crash of the spaceship,

He was also undergoing cryogenic hibernation, and after the ship's crash, he lost his stored information.

So if you calculate carefully, he hasn't seen news from the earth for a long time,

And his memory is still stuck on the data packet he saw before he went to sleep,

If you switch to the usual dormant cycle

What he saw when he woke up was supposed to be the data packets that had accumulated chronologically during sleep.

If you read it in order,

He will soon have a rough impact on the current situation of mankind.

However, at this time, because of the loss of staged packets during hibernation,

When he received the message from the earth again, he was like a person who had been in a coma for several years and woke up to see a new world.

It's like reading a novel, skipping a large section in the middle, and looking directly at the back and some don't know why.

At this time, Yang Meng saw the content behind, and this was the feeling,

This feeling made him very uncomfortable,

He can only skip the news section and go directly to the technology equipment update section behind.

After browsing the science and technology section for a while, Yang Meng silently breathed a sigh of relief:

"Fortunately, the upgrading of various equipment on the spacecraft is based on the state of the spacecraft before hibernation, otherwise it would be really troublesome!"

"Xiao Yi will import the equipment replacement part into the data library!"

"Understood! Importing......"

Although there are some information jumps in the science and technology part,

But most of this time jump is focused on theoretical science,

The technology applied to the spaceship, because it is linked to the entity of the spaceship, needs to be manually upgraded by Yang Meng.

Therefore, even if Yang Meng was dormant, the technology transmitted from the earth was still updated from the spaceship itself.

And see all kinds of technical information in the information,

Yang Meng also knew that he might be busy in the next period of time.
