"Your guess is actually like this, in the astronomy community, there were many people who used to guess it."

Lang Tongguang nodded when he heard Fang Yuan's guess and continued to explain: "At the beginning, he believed that the asteroid belt was originally one or several planets, and was formed by splitting and dying when it was affected by some external factors.

"However, after calculations, it was found that the sum of the masses of these asteroids was smaller than that of the moon, so they were not enough to constitute a planet. Later, this hypothesis gradually became less recognized by most astronomers.

"Now the astronomy community believes that the asteroid belt is formed by some rock fragments in the early stages of the formation of the solar system. Because of Jupiter's domineering gravity, it cannot aggregate into planets.

"However, this statement is actually speculation. No one knows what the truth is. The age of the solar system is 5 billion years, and no one knows what happened in such a long period of time.

"If the microorganisms in this meteorite are really native to the solar system, they might give new answers."

After listening to Lang Tongguang's explanation, Fang Yuan thought about it and asked, "The total mass of the asteroid belt is so small?"

"Yes, the sum of the mass of the asteroid belt now does not add up to the mass of the moon." Lang Tongguang confirmed again.

"So, my guess is completely impossible?" Fang Yuan frowned and thought.

Lang Tongguang thought for a moment and replied: "It is not completely impossible. According to the current research of the asteroid belt in the astronomical community, in the early stages of the formation of the solar system, the mass of the asteroid belt was almost the same as that of the earth. It gradually decreased in the subsequent evolution process.

"After all, the size and mass of the asteroid belt are too small, and they are easily affected by the gravity of other asteroids and are sucked over.

"Juzar is a very domineering large planet, more than a thousand times the size of the Earth.

"In the solar system, all planets except Jupiter, Earth, Mars, etc. combined have less than half the mass of Jupiter.

"Everyone should know that in the solar system, the mass of the sun accounts for 99.86% of the total mass of the solar system. It can be imagined that almost all the mass in the solar system is on the sun.

"However, the existence of Jupiter has caused the center of mass of the solar system to be pulled outside the sun, not inside the sun.

"Let me say so. If Jupiter is more massive, it is even possible to become a star.

"So, Jupiter's gravity is very domineering, pulling the asteroid bodies in the asteroid belt to prevent them from forming planets."

Lang Tongguang then explained: "However, from this point, it can be seen that the asteroid bodies in the asteroid belt are easily affected by other planets due to their small mass.

"Over the years, asteroids will be constantly captured by other celestial bodies, and their mass will be constantly reduced.

"According to research, in the early stages of the formation of the solar system, the mass of the asteroid belt was similar to that of the Earth.

"So, there is a possibility that there was originally a terrestrial planet in the orbit of the asteroid belt.

"But now, no more evidence has been found to prove this, and all speculations are just hypotheses."

Everyone discussed the evolution of the asteroid belt.

Then, he turned his attention back to the meteorite microorganisms.

Fang Yuan pointed to the five-meter-diameter meteorite in front of him and asked: "Professor Lang, can you know where this meteorite comes from through analysis?"

Lang Tongguang patiently answered: "Actually, before coming, we had already checked the relevant information and knew the original orbit data of this meteorite. Before approaching the earth, its orbit was indeed near the asteroid belt.

"It can be confirmed that before this meteorite, it was indeed a piece of the asteroid belt. However, its orbit was somewhat offset. It is hard to say whether it came from other galaxies before entering the asteroid belt."

He said this, paused, pointed to a location on the meteorite, and said, "Look at this place, there are traces of cracking here.

"From the traces of this rupture, the meteorite was not so small, but had an impact and shattered into many pieces, which was one of them.

“Perhaps, its orbit changed because of this impact.

"Anyway, based on the current known information, it is not yet certain whether it comes from the solar system or other galaxies.

"If I were to make a choice, I would rather hope it comes from other galaxies."

After Lang Tongguang finished speaking, he sighed indecisively.

"Why?" Fang Yuan asked curiously.

"If this meteorite is really native to the solar system, then it means that your previous guess may be true. If that is true, then the fate of the solar system will be too bumpy." Lang Tongguang sighed.

When everyone heard his explanation, they understood what he wanted to express.

According to Fang Yuan’s guess, there was once a terrestrial planet near the orbit of the asteroid belt.

On this Earth-like planet, there is a species of life, even a species of wisdom.

However, in the end, this Earth-like planet broke into 600,000 pieces. What was the terrible incident caused?

If this guess is true.

This shows that humans are not the first civilization in the solar system. There was already a civilization before humans, but because of a terrible event, it was destroyed in the long river of history.

Now, human beings are facing the same fate.

Fang Yuan took a deep breath and asked, "Professor Lang, will the collision between the Earth and the Star Beast World explode into hundreds of thousands of fragments?"

"This...that is beyond the scope of knowledge I know, and I can't give an answer." Lang Tongguang shook his head slowly.

This question is indeed beyond the scope of astronomy and has already involved the four-dimensional field, and it is indeed not something he can answer.

Fang Yuan thought of another possibility.

If there was a terrestrial planet near the orbit of the asteroid belt, there was a civilization on it.

In the end, this terrestrial planet broke into hundreds of thousands of pieces, as if it had a collision with other planets.

If this guess is true, then what is this so-called impact?

Now the Earth and the Star Beast World are colliding in the fourth dimension. What will happen if they collide together?

Eve understood what Fang Yuan meant, frowned and said, "It should be impossible. The collision between the Earth and the Star Beast World is so slow, it will take twenty years to completely collide. At such a slow speed, even if it hits each other, it will not explode, right?"

Fang Yuan shook his head and said, "That's not necessarily the collision between the Earth and the Star Beast World seems to have happened very slowly, but one thing should not be ignored. The three-dimensional distance between the Earth and the Star Beast World is 1,000 light-years.

"After such a long distance, it took decades to collide, do you still think the collision is not fierce?"
