"Two stars with four planets, this ratio is much lower than that of the solar system, and these four planets are actually rocky planets." This result came as a bit of a surprise to Lynn.

"This should be related to the complex gravitational situation of binary star systems. Only when they are very close to the star will the planet move steadily, and the distant planet will gradually be thrown away by the binary gravitational system and slowly break away from the star that originally circled. Yuan Haochen explained.

"And where will these abandoned planets go?" Smith asked with interest.

"I once built a model to do that." As he spoke, Yuan turned on the computer and began to simulate the operation of several states of the planet.

"You see, when these planets are thrown out by a binary system, if they move slowly, they will fly to the edge of the binary gravitational system, be affected by the entire binary gravitational system, and continue to orbit around the binary system far away. If they are thrown relatively fast, they will keep flying towards deep space. ”

"That's why the number of planets in the binary system is relatively small?" Smith nodded, looking like he had learned something new.

"Strictly speaking, the Alpha Centauri galaxy is a three-star system, but Alpha Centauri C (Proxima Centauri) is too weak, and its gravitational influence on the whole system is very weak." Yuan continued to add, "There are many forms of star systems in the universe, there are single star systems, just like our solar system, there are also double star systems, three star systems, four star systems, and maybe even five star systems. ”

"The Samsung system is complex enough, and how to analyze the operation of the four-star and five-star systems......" Lynn said with great emotion.

"Is it true that the more complex the star system, the less likely it is to give birth to intelligent life and cosmic civilization." Smith continued.

"In ancient China, there was once a myth and legend called Hou Yi shooting the sun, at that time, the sky was composed of ten star systems, human beings were extremely hot and suffering, the hero Hou Yi shot nine suns with a magic arrow, leaving the current one sun, since then the solar system has become a single star system, and the earth has become a planet suitable for human habitation." Yuan Haochen did not answer directly, but told the mythical story eloquently.

"It's a very vivid and imaginative story. It's just a real star, and we can't afford to provoke it. Smith's eyes widened.

"At present, the signal of the Earth Pupil was taken when it had just entered the orbit of Alpha Centauri B, which was still far from the two terrestrial planets in the habitable zone. It is expected that within one to two years, the pupil of the earth will have a chance to approach these two terrestrial planets. At that time, we will be able to get a closer look at these two terrestrial planets. ”

Yuan Haochen said on his face that the clouds were light and light, but in fact, this is a great thing.

Because, this is a great opportunity to observe the natural environment of the two terrestrial planets.

[Pupil of the Earth] ---- [Alpha Centauri BB1] ---- [Alpha Centauri B] (commonly known as the alignment of two stars is the best time to observe.) ）

"If the observations show that they are habitable planets, then there should be a high probability that a new intelligent race will be born on that planet long after the Creator is gone." With a solemn expression, Lynn continued, "Are we ready for this? ”

"This ......" Smith was speechless for a moment, and Yuan Haochen was silent.

There are many aspects of Lynn's hypothetical situation that the Interstellar Exploration Alliance has considered before.

The main mission of their exploration mission is twofold, one is to find the science and technology left over from the Creator civilization world, and use it to save the earth's civilization.

Another mission is to find habitable planets in the Alpha Centauri system, which will become the preferred target for Earth's civilization to escape crises and interstellar migration if there are indeed habitable planets in the system.

Yuan Haochen judged that the Creator's civilized world had at least reached the level of a Level II technological civilization when it left the Alpha Centauri system. All the planets in the entire Alpha Centauri system must have been under the control of the Creator.

There is no evidence that these two terrestrial planets are the planets born of the Creator civilization, and perhaps the main planet of the Creator civilization world has long ceased to exist.

However, Hara believes that every planet in the Alpha Centauri system will leave more or less the remnants left by the Creator's civilized world. So, even if this expedition can't find the main planet of the Creator's civilization world, they still have a chance to find the Creator's civilization relics.

Given the complex three-star system of the Centaur Alpha System, there will be many complex problems for the birth of a new civilization after the Creator leaves. However, 2.1 billion years have passed since the Creator left, and 2.1 billion years is more than enough for the birth of a new intelligent species.

If there really were a new intelligent race on the planet, the problems that Earth civilization would have to face would be much more complex.

First of all, what kind of identity and posture should the Earth civilization take to face them (in the future, we will use "she" to show respect for extraterrestrial creatures.) ）

Cosmic diplomacy!?

War or Peace?

This is an event that has never been touched in the history of the earth's civilization, and it will be a headache to think about.

"A new civilized race, will they have mastered the science and technology of the Creator, after all, they have the right time and place." Lynn made a hypothesis.

"I think it's unlikely, if they had mastered the science and technology of the Creator, then they couldn't have been unaware of the existence of the Earth's civilization. And after the pupil of the earth arrives, it will definitely become their target and be destroyed. Yuan Haochen objected to this, "Judging by all the current indications, if the Alpha Centauri galaxy gives birth to a new civilization species, their technological level will not exceed that of the earth too much, and they may even be in a very primitive stage." ”

"In these ......., could it be that in 2.1 billion years, they have all lived to dogs?" Smith was surprised.

"First of all, these two terrestrial planets are not necessarily the main planets of the Creator civilization, and perhaps their actual natural environment is very harsh. Second, the environment of Samsung's system is too complex, and there may have been many changes of civilization in these 2.1 billion years. ”

Yuan Haochen seemed to remember something between his words, and after a short pause, he continued.

"Well, there's another possibility......" (To be continued.) )
