Chapter 166: Waiting for the Opportunity

According to the current situation, the fleet of unknown civilization is far more powerful than humans.

It is neither good nor bad, neither too many nor too few, so Yue Yuan uses 120 large tracks to calculate the number of main battleships of the fleet of unknown civilization.

Humans only have 10 mountain-class battleships. If the laws of cosmic technology development are universal, then the main battleships of unknown civilizations of the same first-level civilization must also be mountain-class.

Then, the combat power comparison is 1:12.

It can be said that the strength gap is huge.

So if you want to gain more initiative, it is not enough to rely on the asteroid belt for defense. Humans also need to master more information that is beneficial to themselves but not to the other party.

So Yue Yuan then shouted to the first officer in the bridge: "Show me the stars within 50 light years of Aldebaran on the big screen."

"Yes, Commander Yue."

The first officer of the Tianqin turned around and pressed a few buttons on his workbench, and then the original giant gas planet map was shrunk to a corner, replaced by a star map with a dark universe as the background.

Yue Yuan raised his head slightly and squinted his eyes to look at the star map. Then, he raised his hand to switch the screen to remote sensing mode, and then slowly flipped the star map.

There are quite a lot of stars.

Yue Yuan looked at the mark in the lower left corner of the map and found that there were 372 stars of various types within a range of fifty light years with Aldebaran as the center.

Seeing this, Yue Yuan put down his hands and spoke again: "'Light of the Milky Way', connect the dust cloud channel parameters to the star map system, and calculate the possible routes of the unknown civilization fleet, and mark the possible probabilities of the routes for me, without considering special circumstances."

"It has been done according to your requirements."

The 'Light of the Milky Way', which has become a universal quantum computer AI, reacts and calculates very quickly. As soon as Yue Yuan finished speaking, the big screen was refreshed directly, and then all other irrelevant stars were faded, leaving only three specially marked stars.

"These three stars are the possible stars deduced from the dust cloud track." Yue Yuan looked at the star map again. It is certain that if this unknown civilization did not change its route midway due to special circumstances, then their trigger point should be one of these three stars.

"HIP22336, Yujing San, Yujing Zenger."

Yue Yuan muttered the names of the three stars and looked at the route probabilities marked by the calculation results of "Light of the Milky Way".

The straight-line distances of these three stars from Aldebaran are 35.35 light years, 38.5 light years, and 32.82 light years respectively. The route probabilities marked by "Light of the Milky Way" are 26.6%, 28.3%, and 45.1% respectively.

Yue Yuan said that there is no need to consider special circumstances, so "Light of the Milky Way" did not bring the possibility of the unknown fleet changing its route midway into the calculation program, so the sum of these three sets of data is exactly 100%

"Yujing Zenger?" Yue Yuan looked at the line marked with 45.1%, one end of the line is Aldebaran, and the other end is Yujing Zenger.

It's not that the other two stars are impossible, but in line with the idea of ​​guessing the enemy's worst-case scenario, Yujing Zenger must be used as the hypothetical departure point of the unknown fleet because it is the closest.

"32.82 light years!"

After muttering this, Yue Yuan raised his eyelids again and glanced at Capella, which was the starting point of mankind. It was also marked on the star map, 35.99 light years.

Seeing this set of data, Yue Yuan's eyes sparkled and a smile appeared on his face: "Haha, it's a long expedition! Good!"

Fortunately, mankind arrived at Aldebaran first, otherwise the offense and defense would be switched now.

Although this distance is closer than where humans came from, the difference is not too big. Assuming that it also travels at 15% of the speed of light, it will take at least 218 years. If it is 14% of the speed of light, it will be 234 years, which is not much different from the 240 years of mankind.

Not to mention that it is possible to come from HIP22336, Yujingsan, which is farther away.

Since humans are short of various energy materials after a long journey, there is no reason why the other party is still in full condition as a first-level civilization.

In this way, when this unknown fleet arrives at Aldebaran, it must be short of materials and energy.

It is true that after accelerating to the maximum speed, the fleet is flying by inertia, but the statement of flying by inertia is only an ideal state. Considering the deceleration effect of interstellar dust, the engine still needs to add power occasionally.

In addition to the daily energy required inside the spacecraft, the nuclear fusion reactor must continue to work during the voyage.

And because of the thrust-to-weight ratio of the spacecraft, the more fuel is added, the greater the total mass of the spacecraft, so the more fuel is needed to push the spacecraft to 15% of the speed of light. The more fuel, in turn, increases the total mass of the spacecraft, so there is a "fuel line" here.

Precisely because of this reason, the spacecraft cannot ignore the quality of the fuel for the sake of range.

This is why humans, at this stage, or the first-level civilization, need to rely on the star system to stop and refuel for interstellar navigation.

In fact, as long as there is no way to solve the quality problem, this problem will exist.

So Yue Yuan concluded that this civilization must lack energy and materials when it arrives at Aldebaran.

With this information, Yue Yuan has another calculation in his mind. That is: humans can hide first, and then jump out to contact them after the unknown fleet has completed deceleration.

Why not contact them before they decelerate?

Yue Yuan believes that if they contact each other before accelerating, they may adopt some more fuel-saving deceleration methods, such as using the red dwarf in the outer orbit of Aldebaran B to decelerate.

That's right, it's a gravitational slingshot.

Gravitational slingshots can be used not only for acceleration, but also for deceleration.

The gravitational slingshot effect of a red dwarf star is entirely possible to save a lot of fuel for the unknown fleet.

In the process of completing the deceleration, the energy of the unknown civilization will definitely be further consumed.

Of course, there is another possibility, that is, the unknown fleet will not decelerate directly, and then fly forward across Aldebaran. But Yue Yuan has seen the star map. The nearest star to Aldebaran in that direction is about 18 light years away, and the route must be changed midway. Doing so is undoubtedly more risky. There are problems with fuel, supplies and spacecraft maintenance. If you are not careful, you will be buried in the sea of ​​stars.

So he thinks this possibility is not great, unless this unknown civilization is more "frightened" than humans.

Then the best judgment, of course, is to jump out after they complete the deceleration.

As a leader, every judgment of Yue Yuan will directly affect the survival of mankind, so he will try his best to find evidence from the data.

Just like this judgment, the difference between contacting before acceleration and contacting after deceleration is only about ten hours, but the results are different.

Moreover, a lot of useful information can be judged from the opponent's deceleration time. The most important information is how many Gs the unknown fleet decelerated.

The more tired the opponent is, the more scarce the supplies and fuel are, the greater the initiative of human beings.

I have made a plan to make the enemy tired, so how can I not use it?

When the opponent is exhausted, even if the negotiation fails and a war breaks out, human beings will wait for the enemy to tire.

So waiting for the enemy to tire is not just a saying, but a judgment based on the specific situation. If the opponent comes to Aldebaran from a star within 10 light years, it may not be waiting for the enemy to tire, but human beings will be driven straight in.
