One Punch Star Annihilation

"Your guess, in fact, many people in the astronomy community have guessed like this before."

When Lang Tongguang heard Fang Yuan's guess, he nodded and continued to explain: "At the beginning, I thought that the asteroid belt was originally one or several planets, which were split and formed under the influence of some external factors.

"However, after calculations, it was found that the total mass of these asteroids was smaller than that of the moon, so they were not enough to form planets. Later, this hypothesis was slowly rejected by most astronomers.

"The astronomy community now believes that the asteroid belt was formed by some rock fragments in the early formation of the solar system. Because of Jupiter's domineering gravitational force, it cannot aggregate into planets.

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

"If the microbes in this meteorite are really microbes native to the solar system, maybe they will give new answers."

After listening to Lang Tongguang’s explanation, Fang Yuan pondered and asked: "The total mass of the asteroid belt is so small?"

"Yes, the total mass of the asteroid belt now is not as large as 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 while and replied: "It's not entirely impossible. According to the current research on the asteroid belt in the astronomy community, the mass of the asteroid belt in the initial stage of the solar system's formation is about the same as that of the earth. It was in the later evolution process. Slowly decreasing.

"After all, the volume and mass of the stars in the asteroid belt are too small, and they are easily affected by the gravitational force of other stars, and they are attracted to them.

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

"In the solar system, with the exception of Jupiter, all planets, including Earth, Mars, etc., add up to 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 is conceivable that almost all the mass in the solar system is in the sun.

"However, the existence of Jupiter makes the center of mass of the solar system not inside the sun, but is pulled out of the sun.

"Let's put it this way. Jupiter may even become a star if it is more massive.

"So, Jupiter's gravity is very domineering, pulling the stars in the asteroid belt and preventing them from forming planets."

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

"In billions of years, asteroids will continue to be captured by other stars, and their mass will continue to decrease.

"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.

"Therefore, the possibility of an Earth-like planet in the orbit of the asteroid belt still exists.

"It's just that no more evidence has been found to prove this. All speculations are just hypotheses."

Everyone discussed the evolution of the asteroid belt.

Later, he turned his attention back to the microbes of the meteorite.

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

Lang Tongguang patiently answered: "In fact, before we came, we had checked the relevant information and knew the original orbit data of this meteorite. Before it approached the earth, its orbit was indeed near the asteroid belt.

"It is certain that this meteorite was indeed part of the asteroid belt. However, its orbit is a bit offset. It is hard to say whether it came from another galaxy before entering the asteroid belt."

When he said this, he paused, pointed to a location on the meteorite, and said: "Look here, everyone, there are signs of cracks here.

"Judging from the cracked traces, this meteorite was originally not so small, but it was impacted and shattered into many pieces. This is one of them.

"Perhaps, its orbit has changed because of this impact.

"In short, based on the currently known information, it is still uncertain whether it comes from the solar system or other galaxies.

"If there is a choice, I hope it comes from another galaxy."

After Lang Tongguang finished speaking, he sighed insignificantly.

"Why?" Fang Yuan asked curiously.

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

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

According to Fang Yuan's guess, there was once an earth-like planet near the orbit of the asteroid belt.

On this terrestrial planet, there is a kind of life, even an intelligent species.

However, in the end this terrestrial planet was broken into 600,000 pieces. What kind of terrible event caused this?

If this guess is true.

That shows that mankind is not the first civilization of the solar system. There was a civilization before mankind, but it was destroyed in the long river of history because of a terrible event.

Now, mankind faces 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 pieces?"

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

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

Fang Yuan thought of another possibility.

If near the asteroid belt orbit, there used to be an earth-like planet and there was a civilization on it.

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

If this speculation is true, what is this so-called collision?

Now the earth and the star beast world are colliding in the fourth dimension. If they collide together, what will happen?

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, and it will take twenty years to completely collide together. At such a slow speed, even if it collides. Together, it won't explode, will it?"

Fang Yuan shook his head and said, "That's not necessarily true. The collision between the earth and the star beast world seems to happen 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.

"At such a long distance, after decades of collision, do you still think the collision is not intense?"

When Eve heard this thought, she was stunned.
