“The asteroid belt is located between the orbits of fire star and Jupiter. The distance between Earth orbit and fire star orbit is more than 50 million kilometers, so most asteroids are also more than 50 million kilometers away from Earth.”

Lang Tongguang continues to popularize science to everyone: “Although most asteroids are located in the asteroid belt, there are too many asteroids, so there will always be some going out of the asteroid belt.

“This asteroid is an asteroid with an orbit very close to Earth, but because the diameter is too small, humans have not discovered it until recently.

“The temporary number of this asteroid is 810020, but it has been brought back by you now, and this asteroid will disappear in the solar system forever.”

Fang Yuan didn’t ‘t expect to “destroy” an asteroid by himself.

Han Youwei has been listening carefully to Lang Tongguang’s explanation. At this time, he raised his hand and asked: “Professor Lang, I have a question. How are so many asteroids in the asteroid belt? Formed?”

The asteroid belt is like a dust circle nestled in the solar system.

“There are 120,000 named asteroids. If you count the unnamed asteroids, the number is at least 600,000. Add in the small diameter meteors and cosmic dust, the number is really amazing. As for how the asteroid belt is formed…”

Lang Tongguang also showed a thoughtful expression: “There is no final conclusion in the astronomy circle, if you want to hear interesting answers.

“There is an interesting guess. Some people think that there originally existed a planet larger than Earth in the orbit of the asteroid belt.

“Or there may be two large planets. After the two planets collided, they burst into millions of pieces. After 1 billion years of evolution, the present asteroid belt gradually formed “

Fang Yuan blinked his eyes: “If this is the case, then the microbes on this asteroid…”

“There is indeed such a possibility, but it can only be said to be Maybe, after all, there is still no way to determine the reason for the formation of the asteroid belt.” Lang Tongguang not at all gave a positive answer. After all, mankind has not found the answer to this question so far.

Everyone was surprised when they heard this.

If there used to be a large planet in the solar system, near the asteroid belt, and the microorganisms in this meteorite came from this large planet, then…

In other words, in the solar system, besides Earth, there once existed a planet with life.

This kind of probability is amazing. Although it is just a guess, the thought of this possibility makes people’s heart bang bang wild.

Lang Tongguang saw the expressions of several people and knew what they were thinking. Said with a smile: “Don’t be too real. This is just a guess, and it must be true.

p>

“Furthermore, asteroids like this may have floated from other galaxies and stayed in the solar system after being caught by the sun’s gravity.

“So, even if there was a large planet near the asteroid belt, it cannot prove that there was life on it.”

Fang Yuan asked again: “If you think about this small planet It should be possible to get some information from the planetary material testing?”

“You have to bring some samples back for research, and I can’t give an answer yet.” Lang Tongguang replied.

Fang Yuan nodded thoughtfully, and then asked: “Then the professor thinks that the microbes on this asteroid are more likely to come from where? Is the probability from within the solar system great?”

“This…”

Lang Tongguang frowned, replied: “This is really difficult to give an answer.”

Just when several people were talking.

A researcher of the Institute of Biological Research handed Lu Xiuwen the report of the microorganism.

Lu Xiuwen opened it and read it carefully.

The others next to you also wanted to know the result, so they all gathered around to watch.

“How? What did the report say.”

Since this report is a relatively professional report, it is difficult for laymen to glance at it at first glance.

Lu Xiuwen explained while watching: “From the preliminary test, the first thing that can be determined is that the microorganisms on this asteroid are carbon-based.”

Speaking of this, it contains a lot of information.

First of all, the microbes of this asteroid are carbon-based, which means it has nothing to do with Star Beast world.

Since Earth and Star Beast world are embedded in the fourth dimension, meteorites appearing in outer space may not necessarily come from the solar system, but may also come from Star Beast world.

So, before seeing this report.

It is impossible to determine what galaxy the microorganisms on this asteroid come from.

If these microorganisms are silicon-based, it is basically certain that they are microorganisms from Star Beast world.

Now that the microorganisms on this asteroid are indeed carbon-based, that ruled out the possibility of being from Star Beast world.

However, this answer makes people’s hearts twitchy again.

On an asteroid from outer space, microorganisms appeared, and they were carbon-based, which meant that besides Earth, there was another planet with life.

This planet does not come from Star Beast World, but the nine planets of the solar system can basically be considered lifeless, at least there are no intelligent species.

Then there are two possibilities for the microorganisms on this asteroid.

The first type is that the microorganisms on this asteroid come from outside the solar system, which means that there may be a planet with life in the neighboring galaxies of the solar system.

second, the microorganisms on this asteroid come from the solar system.

If this is the case, then there may have been a planet with life in the asteroid belt orbit of the solar system, and these microorganisms may be the legacy of the disappeared planet.

When Fang Yuan thought of second probability, there was a flash of light in his eyes, and he asked quickly: “Professor Lu, can you be sure that these microorganisms come from outside the solar system? Or are they inside the solar system?”

Lu Xiuwen slowly shook his head and replied: “This…cannot give an accurate answer, but judging from the structure of these microorganisms, there is a certain similarity with Earth’s microorganisms.

” It is certain that these microorganisms have never existed on Earth. In other words, these microorganisms should not come from Earth.

“But because these microorganisms are similar to Earth’s microorganisms, the living environment of these microorganisms should be similar to Earth’s.

“So, these microorganisms may indeed be From the inside of the solar system. “

Fang Yuan’s eyes widened: “In this way, the probability of the existence of life planets in the orbit of the asteroid belt is great? “

“This kind of probability does exist, but there is no direct evidence to prove it. “Lang Tongguang agreed with this speculation, but was not certain of the conclusion.

Fang Yuan took a short breath, scanned the crowd, and said: “I thought of a terrifying speculation, if the solar system had ever There is a life planet, and this life planet is broken into cosmic dust.

“So, is it possible that this life planet in the solar system also encountered a crisis like Earth, and was finally destroyed by higher civilization…”

Everyone heard This guess, while opening his eyes wide, showed a look of astonishment.
