Vol 4 Chapter 704: Terrible guess

"The asteroid belt is located between the orbits of Mars and Jupiter. The distance between the orbit of the Earth and the orbit of Mars is more than 50 million kilometers, so most asteroids are also more than 50 million kilometers away from the Earth."
Lang Tongguang continued to spread 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 whose orbit is very close to the Earth, but because its diameter is too small, humans have not discovered it until recently.
"The temporary number of this asteroid is 810020, but it has now been brought back by you. From now on, this asteroid will disappear in the solar system forever."
Fang Yuan didn't expect to "destroy" an asteroid by himself.
Han Youwei has been listening carefully to Lang Tongguang's explanation. At this time, she raised her hand and asked: "Professor Lang, I have a question, how did so many asteroids in the asteroid belt form?"
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, plus meteors with a small diameter and cosmic dust. The number is really amazing. As for how the asteroid belt is formed of……"
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 was a planet larger than the Earth in the orbit of the asteroid belt.
"Or there are two large planets. After the two planets collided, they burst into millions of pieces. After billions of years of evolution, the current asteroid belt gradually formed."
Fang Yuan blinked his eyes: "If this is the case, then the microbes on this asteroid..."
"This possibility does exist, but it can only be said to be possible. After all, there is no way to determine the reason for the formation of the asteroid belt." Lang Tongguang did not give a positive answer. After all, humans have not found this question so far. answer.
When everyone heard this, their hearts were surprised.
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 the earth, there used to be a planet with life.
This possibility is very surprising. Although it is just a guess, the thought of this possibility makes people's hearts beat wildly.
When Lang Tongguang saw the expressions of several people, he knew what they were thinking, and said with a smile: "Don't be too real. This is just a guess, and it must be true.
"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 test the asteroid's material, you should get some information, right?"
"You have to bring some samples back for research. I can't give an answer yet." Lang Tongguang replied.
Fang Yuan nodded thoughtfully, and asked: "Then the professor thinks, where is the more likely that the microbes on this asteroid came from? Is it possible to come from within the solar system?"
"This one……"
Lang Tongguang frowned and replied, "It's really difficult to give an answer."
Just as a few people were talking.
A researcher from the Institute of Biology handed the report of the microorganism to Lu Xiuwen.
Lu Xiuwen opened it and read it carefully.
The other people nearby 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 as he watched: "From the preliminary test, the first thing that can be determined is that the microorganisms on this asteroid are carbon-based."
Speaking of this, there is a lot of information.
First of all, the microbes of this asteroid are carbon-based, which means it has nothing to do with the star beast world.
Since the earth and the star beast world are embedded in the fourth dimension, meteorites that appear in outer space may not necessarily come from the solar system, but may also come from the star beast world.
So before seeing this report.
It is impossible to determine what galaxy the microbes on this asteroid come from.
If these microorganisms are silicon-based, it is basically certain that they are microorganisms from the world of star beasts.
Now that the microbes on this asteroid are indeed carbon-based, the possibility of coming from the star beast world is ruled out.
However, this answer makes people's hearts twitchy again.
Microorganisms appeared on an asteroid from outer space, and it was carbon-based, which meant that besides the earth, there was another planet with life.
This planet does not come from the world of star beasts, but the nine planets of the solar system can basically be regarded as lifeless, at least there are no intelligent species.
Then, there are two possibilities for the microorganisms on this asteroid.
The first is that the microbes on this asteroid come from outside the solar system, which means that there may be a planet with life in the neighboring galaxy of the solar system.
The second type, the microbes 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 the second possibility, there was a gleam in his eyes, and he asked quickly: "Professor Lu, can you be sure that these microorganisms come from outside the solar system? Or inside the solar system?"
Lu Xiuwen slowly shook his head and replied: "This...can't give an accurate answer, but judging from the structure of these microorganisms, there is a certain similarity with the earth's microorganisms.
"It is certain that these microorganisms have never existed on earth. In other words, these microorganisms should not come from the earth.
"But because of the similarities between these microorganisms and those of the earth, the living environment of these microorganisms should be similar to that of the earth.
"So, these microorganisms may indeed come from the inside of the solar system."
Fang Yuan's eyes widened: "In that case, it is very likely that there was a life planet in the orbit of the asteroid belt?"
"This possibility 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 breathed a little bit faster, scanned the crowd, and said: "I thought of a terrible guess, if there was a life planet in the solar system, and this life planet shattered into cosmic dust.
"So, is it possible that this life planet in the solar system also encountered a crisis like the earth, and was finally destroyed by higher civilization..."
When everyone heard this speculation, they opened their eyes wide and showed expressions of astonishment.
