In fact, there is a problem with this problem itself. Who said that the sun in the three-body world didn't devour the three-body planet? There is only one lucky one left.

The first question: What kind of world is the three-body world? In fact, the three-body world is different from what most people think. The three-body world is a general term for three-body stars, namely three suns and twelve planets. Three-body civilization is not necessarily born on one planet, and it is not necessarily only experienced nearly 200 rounds as said in the game. These three-body civilizations that eventually invaded the solar system did not know themselves.

According to the astronomical speculation of scientists in the three-body world, there were originally three suns and twelve planets in the three-body world, but in the long history, eleven of them were swallowed up by the three-body sun, leaving only the last planet for the survival of the three-body civilization. However, this planet is not peaceful. In the 19 1 civilization, we met the "flying stars don't move". This disaster is the biggest disaster in the history of three-body planet. Not only did life become extinct, but it took 90 million years for civilization to be reborn. And the whole three-body planet was torn in half, and a small part of it finally evolved into a three-body satellite.

That is to say, when humans discovered the three-body civilization, the three-body world was composed of three suns and a planet, and the planet had its own satellite, namely the three-body moon. These five celestial bodies constitute the whole three-body world.

The second question: There are three suns in the three-body world, and their movements are irregular. Why didn't they swallow those three bodies? This problem is actually more complicated. If you really want to find a seemingly appropriate reason to sum it up, you can only say that it is luck. What keeps them from being swallowed up by the three suns is the luck of the three-body world. But there are some inevitable factors behind this luck:

Firstly, it is based on astronomical scale: although the three-body world is a chaotic system and the three suns run irregularly, it is based on astronomical scale after all. In the time that a person or a civilization can experience, the three-body world is still a relatively stable system as a whole. For example, although disasters occur frequently in the three-body world, disasters that directly tear the planet like flying stars are not frequent. Most of the disasters experienced by the three-body world are dominated by extreme climate. In the long 200 rounds of civilization, the three-body planet has not suffered much damage, and there has never been a tragic situation in which three suns collided.

Secondly, the special case of the three-body planet: the three-body world can form a chaotic system because the masses of the three suns are not much different, that is to say, the intensities are basically the same. Just like an eagle catching a chicken, when three suns with equal strength face twelve planets, each sun naturally catches and devours a planet easily. However, with the decrease of the number of planets, so that there is only one planet, it is extremely difficult for any of the three suns to take this planet from two competitors, and it will be interfered by the gravity of the other two suns. So as long as it is not an extreme case, the three-body world can still survive under normal circumstances.

The third question: since it is difficult for three suns to swallow the three-body world, why should the three-body people invade the earth at all costs? This involves another problem. Although it is difficult for the three suns in the three-body world to swallow the three-body planet by gravity, these three suns have a creepy feature, that is, star breathing. That is to say, in a certain period of time, the peripheral gas layers of the three suns will contract and expand periodically. In other words, if before the twelve planets, three suns devoured the planet by catching their own chickens, then now three suns carve up a planet at the same time, and the three-body planet can no longer escape the fate of being devoured.

Before the 192 civilization invaded the earth, it was predicted that the three-body sun would breathe stars in150-2 million years, so the three-body world began to prepare to find a new home from this round of civilization. After the birth of the civilization that invaded the earth, the situation has been very critical, and there is not much time left. This is why the Fuehrer said to the Commander-in-Chief of the Three-body First Fleet: Look at the three suns in our galaxy, and the gas layer of any one of them may expand at the same time, engulfing our last planet. Therefore, there is no choice but to take risks.

It is also for this reason that the first fleet, without knowing the distance and position of the earth, only carried fuel that slowed down once and set out for the solar system with the determination to die.

Committed to science, science fiction, focus on depth, welcome friends who like science fiction to pay attention to: deep science fiction! Three people are also afraid of being swallowed up, so they have been studying the running laws of the three suns, and then they can't find a solution before flying into the universe to find a new home.

It will be swallowed, and it is written in the book that swallowing is inevitable, only a matter of time. This is why Santi people are highly concentrated, and so many listening stations have been built to find a planet suitable for their immigration. . .
