Chapter 709: Titius-Bode Rule

"Actually, this sequence is the Titius-Bode rule, which was discovered by two German scientists. Not only the planets in the solar system have such a rule, but most galaxies have similar characteristics, and even the satellites orbiting planets have similar characteristics. Most of them conform to this rule.”

After Han Youwei explained the meaning of the sequence, Lang Xiaonian made a final addition: "For this reason, I always believe that there was originally a planet between the orbits of Mars and Jupiter, but it was destroyed by external forces."

The universe is too vast, and the more human beings want to explore the universe, the more they feel their insignificance.

at night.

Several members of the team gathered at Fang Yuan's house, and Lang Xiaonian was also invited to eat hot pot.

The night sky is full of stars.

Han Youwei rested her chin, looked at the galaxy in the sky, and sighed leisurely: "You say, where is the asteroid belt?"

Lang Xiaonian continued: "Actually, the asteroid belt cannot be seen with the naked eye, and even Ceres, the largest in the asteroid belt, cannot be seen with the naked eye. The absolute magnitude is too low."

"How big is Ceres?" Eve asked.

"The diameter of Ceres is almost 1/4 of the moon, and it is the largest one in the asteroid belt. Because it is too far away, it cannot be seen with the naked eye. In fact, all the stars we see at night are actually Stars. Only when stars burn and emit light can we see them with the naked eye." Lang Xiaonian answered.

"You said, do we have the opportunity to explore the asteroid belt ourselves? If there was a civilization there, maybe there will be something left." Han Youwei continued to sigh.

"Maybe there will be a chance to visit the asteroid belt." Fang Yuan also sighed.

Niu Dazhi had seen the star map of the asteroid belt before, and wondered: "The asteroid belt is full of floating stars and cosmic dust. If the spacecraft flies past, won't it be hit and sunk?"

Lang Xiaonian shook his head and replied: "Under normal circumstances, there is no danger in flying a spaceship close to the asteroid belt. In fact, according to the estimates of the astronomical community, there are countless stars and rocks in the asteroid belt. Absolutely More than two million pieces.

"All the stars and rocks revolve around the sun, and from the star map, they seem to be densely packed.

"However, the density of stars in the asteroid belt is actually very low. After all, the width of the asteroid belt exceeds 200 million kilometers. On such a wide scale, the probability of hitting a meteorite is very small, the probability is less than one in 100 million.

"Moreover, the spaceship has radar and can choose to avoid it, so theoretically there is no danger. Of course, if an accident occurs and the spaceship hits any meteorite, something big will happen."

Niu Dazhi also began to hold his chin, and sighed: "Do you think the earth will really be smashed to pieces by higher civilizations?"

"Maybe. If we attract the attention of higher civilizations." Fang Yuan thinks this possibility is very high.

Moreover, the earth has long been discovered by advanced civilizations.

Since the members of the team learned that there might have been an terrestrial planet destroyed by advanced civilizations in the orbit of the asteroid belt, they suddenly felt a sense of urgency for the survival of civilization.

In the yard, Fang Xiaozhu was the only one who didn't feel this serious emotion, and was still playing with Xiong Ba.

...

the next day.

Fang Yuan went to the Advent Civilization Research Building of Academy of Military Sciences.

The purpose of this trip is naturally to see "Rahu".

Rahu was still locked in a cylindrical transparent container.

The body in the energy state is usually in a chaotic state, but when Fang Yuan appears, he will converge into a human form.

"You're here? You can't cope with the star beast civilization, are you ready to ask me for help?" Luo Hu's tone of voice revealed the arrogance unique to high-level civilized creatures.

"It seems that your news is really closed, we don't need you to deal with the star beast civilization." Fang Yuan showed a very calm attitude.

Luo Hu narrowed his eyes slightly and guessed, "At this time, it is impossible for you to deal with the star beast civilization."

"It's just a matter of time, star beast civilization is just a group of beasts that rely more on instinct than brain. It's not that difficult to deal with. In fact, the civilization behind you is what humans should really worry about." Fang Yuan pulled a chair Sit down and start chatting with him.

Speaking carefully, it has been a long time since I came to see this unexpected guest of Palesi's soul descending civilization.

"You think too much, the civilization behind me, you don't need to worry at all, because you have no right to worry. As long as we want, we can even destroy the entire solar system. Is your worry useful?" Luo Hu sneered.

"Isn't it the first time you have launched a galaxy-level attack on the solar system?" Fang Yuan tentatively asked.

Luo Hu showed an expression of great interest, and asked, "Want to get information from me?"

"Just chatting, you should also be curious about what happened outside, right? Don't you want to chat with someone? On Earth, maybe I'm the only one willing to chat with you." Fang Yuan put on an expression that didn't really care .

Rahu has been imprisoned for too long.

This feeling of being locked in a glass container hurt him more than killing him.

At the beginning, researchers came to ask him questions from time to time.

Later, gradually no one communicated with him, and this feeling made him very uncomfortable.

Therefore, when he saw Fang Yuan coming in, the urge to speak almost burst out.

Moreover, he was locked in the container without any news from the outside world, and he didn't know what was going on outside. This feeling of darkness was like trying to open his eyes wide in the endless night, but he couldn't see anything. arrive.

"It's okay to chat, what's going on outside?" Although Luo Hu really wanted to hear some news about the outside world, he still had the arrogance of a high civilization, and his tone was still arrogant.

"I can tell you a piece of good news, maybe it's bad news for you, we have developed controllable nuclear fusion technology. Planetary gravity is no longer the shackles that shackle human beings, and human beings have mastered the power to fly into the universe." Fang Yuan Said the biggest thing that happened during this time.

"Controllable nuclear fusion technology, judging by your expression, seems very proud, but to me, it's as ridiculous as saying that you have developed a lighter." Luo Hu sneered.

Fang Yuan was not affected by his sarcasm at all, he twitched the corner of his mouth and said with a smile: "You came to Earth from the Star Beast World through a space rift, is this the first time you came to the solar system?"

"Of course, do you think I will go to a barren galaxy many times? It's not that I want to ridicule you. Your galaxy is barren, barren, and almost undeveloped. It's like a barren land." Luo Huo A positive answer was given.

"Then have you heard of the solar system before? In the orbit of the asteroid belt, the original terrestrial planet, you were killed by you, right?" Fang Yuan revealed a sharp look in his eyes, and began to test.
