The report ended at nine o'clock, and the questions were eased for another half hour.

Fu Wenhe stepped down, shook hands with the school leaders of Imperial Capital University, and walked backstage.

Fang Yuan still had some questions he wanted to ask, so he got up and walked over, shook hands with Fu Wenhe, and then walked backstage together.

"Professor Fu, I still have some questions, can I ask?"

Fu Wenhe looked at Fang Yuan, recognized Fang Yuan's identity, and replied very enthusiastically: "Of course, of course, sit down and talk." ”

The group found chairs to sit in the backstage of the auditorium, and there were staff walking around to put the finishing touches on the briefing.

"What do you want to ask?" Fu Wenhe took the initiative to ask.

He knew that Fang Yuan was a super soldier selected by the military scientific research class, that is, the top combat power in Huaxia in the future, which would have a huge impact on Huaxia and even the future of mankind.

"That's right, some time ago, when Shenzhou was on a test flight, it brought back a meteorite from outer space, and there are non-terrestrial microorganisms in the meteorite, Professor Fu should know about it, right?" Fang Yuan first mentioned the matter of meteorite microorganisms.

"I know, I discussed this matter with Lang Tongguang." Fu Wenhe nodded.

He and Lang Tongguang are both scholars in astronomy, so they occasionally discuss some academic issues.

The matter of meteorite microorganisms is a frontier topic in several university disciplines such as astronomy and cosmic sociology, and he will naturally pay attention to it.

"The emergence of meteorite microorganisms has increased the possibility that there were terrestrial planets in the orbit of the asteroid belt. Fang Yuan asked.

"From an astrometric point of view, based on the orbits of the eight planets, there really should be a planet there. Recently, however, in the astronomical community, more people believe that it is the gravitational pull of Jupiter and the Sun that has torn the planet apart. Professor Lang Tongguang believes that Jupiter's gravitational pull is too domineering, resulting in the inability of material in the orbit of the asteroid belt to aggregate into planets. Fu Wenhe pondered and preached.

"What does Professor Fu think?" Fang Yuan asked.

"Before the discovery of microorganisms in meteorites, I agreed with Professor Lang Tongguang's view. However, after seeing the research report on meteorite microorganisms, I was somewhat biased towards the idea that there was once a terrestrial planet there......"

Fu Wenhe continued to express his opinion: "That location is very close to the earth, and there is indeed a possibility of forming terrestrial planets. The fact that the microbes in the meteorites come from the interior of the solar system indirectly confirms this.

"So, maybe the Earth was in the Cretaceous Period, or maybe there was no life on the Earth, and it was already a living planet."

Fang Yuan continued to ask: "Then let's assume that there was indeed a terrestrial planet in the orbit of the asteroid belt. So what did the creatures living on this terrestrial planet do? What was left behind when destruction came? ”

Fu Wenhe shook his head slowly and said, "It's hard to get an answer to this question, if there was once a terrestrial planet there, then this terrestrial planet was shattered into countless pieces, and now the mass left is less than one ten-thousandth of the original."

"Unless one day humanity can reach the asteroid belt and search for traces of civilization that may be left there, there will never be an answer to this question."

Fang Yuan bowed his head in agreement, and then asked, "Suppose there was once a civilization on that terrestrial planet. If we analyze it in terms of cosmic sociology, what will this civilization do before it is destroyed? ”

"Survival. This is the main body of life, whether it is reproduction or the continuation of civilization, it can be boiled down to survival. ”

After thinking about it seriously, Fu Wenhe continued to add: "Just like human beings, if the earth is facing the same crisis of destruction, then the first reaction of human beings must be to survive and continue civilization.

"If you can't resist, then fleeing is the first option, provided that the civilization has the technology to escape the solar system."

In fact, humans have the same mindset.

The Tinder Project is actually a plan to continue civilization and send the flame of civilization away from the solar system.

"So, maybe outside the solar system, there is a possibility that there is a civilization that has left the solar system?" Fang Yuan followed his train of thought.

Fu Wenhe shook his head and said, "This is unlikely. This civilization in the orbit of the asteroid belt, if it really existed, could be hundreds of thousands, millions, or even hundreds of millions of years ago.

"For such a long time, if this civilization still exists, then the solar system, as their home galaxy, will definitely be concerned.

"Then when human civilization emerges, there should be information contact, even if it is only a one-sided transmission of information.

"Therefore, I prefer this civilization in the asteroid belt, the technology level is not too high, and there is a high probability that it has disappeared in the long river of time."

Fang Yuan bowed his head again, expressed his approval, and asked again: "If this is the case, then what does Professor Fu think such a civilization will do before it disappears?" ”

"It's still survival, and if you can't survive physically, then you will pursue spiritual survival. This is another understanding of survival for intelligent life......"

Fu Wenhe gestured with his hand to draw a circle, and then said, "Let's take human beings as an example. If human civilization is about to be destroyed, then the first thing that can be thought of is to continue the flame of civilization, send the flame of civilization out of the solar system, and find the possibility of revival.

"If you can't even send the flame of civilization, then you can only choose a more helpless way, record the history and culture of civilization, and use the last bit of strength to prove that you have been in this world."

Fang Yuan nodded again in agreement: "That's right, if the human race is going to be destroyed, it should also want to record history and culture. ”

The most direct way, naturally, is to record history and civilization on the hard drive, as proof that civilization once existed.

However, if it is recorded on a hard drive, it will not be kept for long.

On the scale of the universe, it is hundreds of millions of years.

100 million years is not enough for the earth to develop from the Cretaceous to the modern era, and hard disks cannot be preserved for that long.

Fu Wenhe turned his head to look at the night sky outside the window.

Tonight's night sky is clear, full of stars, like a jewel hanging in the sky, twinkling with quiet starlight.

He sighed leisurely: "Perhaps, in the asteroid belt, there are still traces left by that civilization, if you can go there one day, maybe you can find the traces of civilization left by them." ”

"There will be a chance, we have mastered controlled nuclear fusion technology, and we are fully capable of flying into space."

Fang Yuan replied with a smile, his tone was full of vitality, which made Fu Wenhe feel a sense of vigor in his heart.
