"Restrictions?"

Seeing Xiaoguang say such a thing, Yang Meng groaned,

He also knows the difficulty of this technology,

He has communicated a lot with Xiaoguang on this technology,

Gravitational lensing,

As early as the beginning of the 21st century, human beings have been used in the field of astronomical observation and are an important tool for observing exocelestial bodies.

This observation method uses the gravitational force generated by massive celestial bodies to distort space, and forms a convex lens-like effect, so that human beings can observe the cosmic space behind massive celestial bodies.

In a nutshell

It is to use massive celestial bodies as magnifying glasses to observe the cosmic space behind them.

With this technology, mankind has discovered some extremely distant celestial bodies.

But if you want to use gravitational lensing,

A prerequisite is needed - a massive celestial body,

Only the space distortions created by a celestial body of sufficient mass can serve as a noticeable magnifying glass.

Especially those celestial bodies that do not emit light on their own, are more suitable to be magnifying glasses,

In the universe, humans often look for magnifying glasses for massive black holes without obvious accretion disks.

With the increase in the precision of human astronomical observation technology,

Humans can already take advantage of gravitational lensing at the stellar level,

This technique is called microgravitational lensing.

This technology is an important tool for observing planets.

In the early twenties of the 21st century, researchers from Shanghai Jiao Tong University demonstrated the theory of relativity at the nanoscale.

This also proves to a certain extent that

As long as there is mass, the object can use its own mass to cause bending in space to achieve the effect of a magnifying glass.

Of course, this is just a theory, with the observation technology of human beings at that time, they wanted to see clearly what was behind a massive object through a magnifying glass.

can only go to the more massive stars,

But the Rutans are different from the humans on Earth,

They have never been able to leave their own planet, and can only observe the universe through some methods.

Therefore, in terms of technology such as gravitational lensing, it is far further than human beings.

Especially in the world of string theory, the observation accuracy of gravitational lensing has surpassed the degree that human imagination can be.

In this case,

Using such a small star to observe Planet B behind it, the Rutans can do the following with their technology:

"However, Xiaoguang said that their technology has certain limitations!"

Thinking of limitations,

Yang Meng can also think of some,

The first is that the star is too small, and the second is that the observer seems too close to the star and the planet to determine the location of the observation.

"But what are the limitations?"

These thoughts flashed through Yang Meng's mind, and then he looked at Xiaoguang,

Xiaoguang felt Yang Meng's gaze, flickered and said:

"This star is too small......"

"But with your microgravitational lensing technology, such stars can be exploited!"

"Yes, but the accuracy of the observation is very high!"

"In that case, this technology can still be tried!"

"But the distance here is too close, the degree of information aggregation is not high, and there may be some problems with the clarity of the available information!"

Seeing that Xiaoguang really said the two questions he was considering, he opened his mouth and asked:

"Can such a problem be overcome?"

Hearing this, Xiaoguang flickered and continued:

"It can indeed be overcome!"

"But to overcome, it has to do with the third limiting factor that I will talk about next!"

"Is there anything else......" Seeing Xiaoguang talking about the part he didn't consider, Yang Meng listened patiently,

"We want to see the planet behind through gravitational lensing, which is not difficult for the technology I have mastered.

The really hard part is how do we translate what we see into information that can be understood.

To do this, I need extremely sophisticated information processing aids! ”

"As long as we solve the problem of precision, then even with the first two limiting factors, we can see what is going on on that star!"

Hearing this, Yang Meng instantly understood that the technical problems that Xiaoguang said,

Humans have been in this situation before,

Early humans observed the universe through optical astronomical telescopes.

But the visible range of the human eye is very limited.

So radio astronomical telescopes with a wider field of view appeared.

early radio astronomy telescopes,

The data collected is either a complex wavy line like an electrocardiogram, or a dense collection of binary or hexadecimal numbers.

Even professional astronomers, looking at such data, will feel big,

Until the development of human computer technology,

The data collected by radio astronomy telescopes can be processed in images, and it is only in combination with optical observation that human observation becomes easier.

And at this time, the situation he faced was very similar.

Through the microgravitational lensing technology of the Rutans,

Although it is possible to gather information from the planet Ross 128b,

But how to sort out the collected information is a difficult problem.

The difficulty of this information collation is like mixing a small amount of salt and a lot of sugar.

Without going through chemical methods,

It is as difficult to pinch out the salt particles one by one with tweezers only through a magnifying glass.

"So how did you find the data on your target planet from the vast amount of interference information in the first place?"

Yang Meng looked at Xiaoguang and asked such a question.

"Time!"

Xiaoguang's answer was very brief,

"When?"

Under Xiaoguang's reminder, Yang Meng recalled the answer he gave to Xiaoguang how he saw the earth's scene.

reflected photons and other particles from the Earth,

Even after the convergence of stellar magnifying glasses,

By the time Rutan Star has almost reached the point of none,

But for the Rutanan civilization that has existed for more than a billion years,

As long as there is enough time, the observation data from the earth will be retained,

And then it's like picking salt from sugar, as long as you have the tools, you can distinguish the difference between the two and take the salt out.

Even if the process of removing it is extremely cumbersome and cumbersome,

But as long as you can take it out, it will take a lot of time, and one day you will be able to get all the salt out of the sugar.

And the discovery extraction tool used by the Rutans here is the string theory.

The string theory in the microscopic world has a lot to do with the direction of the particle's spin motion and oscillation data.

And in the universe, time, space, and changes will affect these data.

This makes it possible for particles that reach a planet from different distances and directions,

There is a difference in the world of string theory.

It's a pity that string theory is not a technique that Yang Meng can master today.

Some of the string theory knowledge he had acquired from Xiaoguang had been transmitted to the earth.

But alas, until now he has not received any information about this,

Something about string theory, flashed through his mind,

Although some are worried about the situation on the earth, they are also worried about the problem of communication,

But the most important thing now is to figure out the situation on planet Ross 128b.

He had forgotten all these questions.

"In any case, although there are certain limitations, it is still possible to use microgravitational lensing to make some observations of Ross 128b, right?"

"Yes!" Xiaoguang flickered and responded:

"It's just that our observations may be fruitless!"

"And you'll have to help me make some auxiliary equipment so I can make observations!"

"Yes!"

"Wait, it's not over yet, if you want to take advantage of the microgravitational lensing effect, the spaceship you're in needs to temporarily break away from your so-called Lagrange L3 point,

We need to find the right viewing angle! ”

Seeing that Xiaoguang kept making requests and proposing to change the position of the spaceship, Yang Meng thought for a while and responded:

"Yes, as long as the spacecraft doesn't move to the other side of the star......"

"How is it possible to move to the other side of the star!"

Xiaoguang flickered for a moment, and seemed to feel a little strange about Yang Meng's speech.

……

After deciding on two detection methods,

Yang Meng got busy,

The first thing he prepared was to point to the 4:5 position and launch the mirror.

This preparation, not troublesome, soon two devices were launched,

Although Yang Meng called it a mirror,

But it's essentially two satellites.

It's just that unlike ordinary satellites,

Mirror 1, and Mirror 2, each with a large and a small pot on each of the two satellites,

These two pots are the tools that Yang Meng uses to collect information.

When the Mirror satellite arrives in the target area,

The cauldron will be aimed at the planet Ross 128b,

The small pot adjusts the angle to the position of the spacecraft,

Among them, the cauldron does not actively emit any signals, but collects any tiny movements from Ross 128b,

Then, through the cluster signal channel of the small pot, the cluster signal as much as possible is transmitted to the location of the spacecraft.

When the two mirrors are sent out,

Yang Meng took a break and then continued the next preparations.

He looked at the list of equipment that needed to be built next,

There was some hesitation when noticing that one of the devices that goes with the mirror,

"Neutrino detection device?"

Yang Meng thought for a moment and temporarily pulled the equipment out of the equipment to be built.

Although neutrinos are the most penetrating particles discovered by mankind today,

In addition to black holes, neutrinos can pass through these objects, whether they are neutron pulsars in a degenerate state or stars.

But taking into account the situation on planet Ross 128b, and the fact that the pioneer astronauts on this planet have the same technology as him,

He doesn't use active detection until he decides on something.

"When we were close to Planet B, maybe we should use neutrinos to probe it......"

Yang Meng, who thought of something, shook his head gently,

The remaining equipment of the mirror detection program continues to be refined.

Aerospace engineering is a highly systematic project.

Two mirrors alone are not enough to accurately detect Ross 128b.

Fortunately, with the support of 3D printing technology,

The rest of the equipment was also quickly sent.

And the next time is to prepare the auxiliary equipment of the microgravitational lensing for Xiaoguang.

……

In the blink of an eye,

Yang Meng has been hiding on the other side of the Ross 128 star for more than half a month.

Because the Ross 128 galaxy is a tiny galaxy,

So in this half month,

The two mirrors have reached their respective positions and some work has begun.

And Yang Meng on the spaceship,

It's like, a spy with a bugging headset in one hand,

Detecting the situation on the planet Ross 128b,

"No! Nothing! ”

"And the state of point four and point five is far more complicated than expected!"

After a day of listening, Yang Meng had already discovered some problems with this plan.

Although it is possible to monitor the situation on planet B in real time,

But points four and five, as the two most stable of the five Lagrangian points,

The tiny celestial bodies in it are too complex,

His two mirrors can only be docked to the outside of two points,

Even so, it is still inevitable to be disturbed.

"In this case, I don't know how long the mirror will last!"

Yang Meng put down the monitoring data in his hand,

Drifting away from the equipment bay, he went to find Xiaoguang.

Soon he found Xiaoguang,

It's just that the small light at this time is not in the cabin, but in a spherical device outside the cabin.

The upper part of the device is covered by a translucent structure.

The lower part is a metal semisphere of some kind of entity.

At this time, the small light was flickering slightly in this ball, as if it was doing something.

"It seems that Xiaoguang is still working on information gathering!"

Seeing this scene, Yang Meng didn't disturb Xiaoguang, and was about to turn around and leave.

But at this moment, Xiaoguang's voice reached his ears through the communication device on the spaceship:

"It's time for the ship to move its position!"

"What a direction!"

"I've already marked it for you!"

As soon as Xiaoguang's words fell, a star map appeared in front of his eyes,

There is only one bright red star in this star map,

At this time, the position marked by the small light is an area to the right of the star.

"Looks like the ship is poking its head again!"

During this time,

Except for his secret observation of planet b,

Under the command of Xiaoguang, the spacecraft is on the other side of the star Ross 128,

Keep jumping up and down, left and right,

The head of the ship will emerge from the left side of the star,

One will emerge from the right side of the star,

Like a gopher.

Fortunately, the temperature of the star Ross 128 is higher,

According to simulation calculations, even if the spacecraft pops out a little, it will be difficult to notice the unknown presence on Planet B.

It is precisely because of this that

Yang Meng will agree to Xiaoguang's plan to take the lead, otherwise......

Although I can't disturb Xiaoguang,

But Yang Meng can still ask Xiao Yin about Xiao Guang's detection status.

Xiao Yin has been observing Xiaoguang continuously during this time,

According to Xiao Yin's feedback, Xiao Guang's observation here was much smoother than expected.

"Is that what it says?"

"Yes!"

"This point of light found that because of its proximity to Planet B, the various particles and reflected photons emitted from Planet B are extremely clear!"

Through Xiao Yin's explanation, Yang Meng quickly understood the degree of clarity.

If you look at the Earth from the Rutan position, it is like distinguishing the salt in sugar.

Then observing Planet B in this position is like looking for a grapefruit among oranges, which is very conspicuous.

"The point of light also said that if their planets could move up and down, left and right like spaceships, they would have discovered their own galaxy a long time ago."
