The core of the solar system is the sun, and once the sun has an abnormality, it will cause heavy losses to mankind, and at worst, human beings in the solar system will be wiped out.

Biosphere 3 is a quarter the size of the moon, and its comparison to the size of the sun is exactly the same as that of a basketball and sesame seeds.

Although the disparity between the two is huge, if the entry of Biosphere 3 into the Sun causes a chain reaction, it will be an absolute disaster for mankind.

Seeing Zuo Dajun say this, Fan Xiaoming nodded and said: "This was taken into account when designing the No. 3 ecosphere, which is why the size of the No. 3 biosphere is controlled at the size of a quarter of a moon, according to relevant research, the No. 3 biosphere will not have much impact after falling into the sun, as for the chain reaction, there is a possibility of occurring, but it will not be too big, and again, pushing the No. 3 biosphere into the sun is a last resort, and it will not be done under normal circumstances."

In just one half year, the study of the sun and the solar system far exceeded the sum of the past years.

According to the model built by the research, it is known that if something the size of Biosphere 3 falls into the sun, the impact will be nothing more than a stone thrown into the water, which can cause a wave.

Of course, this is not to say that the fall of Biosphere 3 into the Sun will not bring about a great change in the Sun, but the probability of such a situation is very low.

Even if it may be small, it will be a last resort to push Biosphere 3 into the Sun.

Zuo Dajun nodded and said, "That's right, this is related to the sun, to the fate of our human race, if we are really so hasty, we human beings don't know how many times we will be destroyed."

"Rest assured, others can think of what we can think of." "Like you said, it's the sun, and no one makes fun of it."

As time passed, Su Zhe and the others got closer and closer to the distance of the four ring devices.

At this moment, four beams of light came from a distance, and without exception, each of the four beams was connected to four annular devices.

Seeing this scene, a few people were startled at first, thinking that these beams were emitted by dead light, but when they saw that the four beam strikes did not react at all on the ring device, everyone understood that this was the beam emitted by the light pillar engineering facility, which was to charge the four ring devices.

Zuo Dajun pointed to the four ring devices and said, "Scared to death, I thought it was a malfunction of the SS-defense system and hit these as asteroids."

If the rally is not good, then there is a problem."

On Earth, the growth of crops depends on the harvest of the sky, and whether it is good or not depends on the weather, but the space farm is different, its environment is completely controlled, and you can have what kind of weather you want.

Naturally, the rise of these crops is better.

Zuo Dajun nodded and said: "This is the basic requirement of the space farm, if this can't be done, then there is no need to engage in a space farm, but then again, the space farm still uses the traditional way to obtain food, I have heard, not long ago a big breakthrough was made, and it can be directly used to produce food in a synthetic way, so maybe it will take a few years, like these space farms, space ranches and so on can be eliminated."

The traditional way of obtaining food is to cultivate crops, which produce seeds under the action of energy and matter, and these seeds are the food that human needs.

This production method requires a large space and a relatively long cycle, under normal circumstances, the staple food is generally about 100 days.

And by using the synthesis method, it can be directly achieved on a large scale.

It directly synthesizes inorganic substances into organic substances such as sugars, proteins, fats, amino acids, etc., and then can be processed and synthesized into rice, flour, sugar and other required materials.

Whether it's the former or the latter, as long as there is energy and resources, there will be a steady stream of food output.

Relatively, the latter has more advantages.

After all, the latter can be synthesized in factories, and its cycle is shorter than the former.

It's just that the former has a high energy utilization rate, while the latter requires far more energy than the former.

Of course, in the current situation, there is a pillar of light project, as long as the sun is not extinguished, then there is a steady stream of energy.

Relatively speaking, it doesn't matter how much energy you use.

Fan Xiaoming smiled and nodded, "Factory synthetic food, I know this, the first thing to do is to synthesize rice, then wheat, corn, etc., seriously, if these synthesized can sprout, it will be no different from the real one, but unfortunately there is still a little worse, of course, there is no problem at all with the synthesized ones that are used for food now."

He had seen the synthetic rice, wheat, and corn, because the Nine Heavens Research Center was one of the participating researchers.

Compared to real rice and wheat, it is difficult to distinguish between synthetic and real ones.

Whether it is in terms of appearance or taste, or nutritional value, energy that can be provided, etc., there is basically no difference.

If there is a difference, it is that the former is alive and the latter is inanimate.

If you really want to talk about it, when you synthesize organic substances such as sugars, proteins, fats, etc., you know that it is not a problem to synthesize rice and wheat on this basis.

The synthesis here starts with the most basic inorganic substances, such as water, carbon dioxide, nitrogen dioxide, etc.

It's just that this synthesis technology is still relatively a little bit worse now, and when the synthesized rice can germinate, there will really be no difference at this time.

When the time comes, it will replace the traditional way of obtaining food, which will be inevitable.

It is not only plants that can be synthesized, but also animals and other types of food.

"If you don't consider the energy utilization rate, the road to obtain food in this way can be passed, but it is still not mature enough, and no one wants to eat such food when it is synthesized, not to mention these synthetics, no one wants to eat it even at this stage of the space farm." Xu Zhengping said.

This is not nonsense.

For now, basically only accept food that is traditionally produced on Earth, and no one wants to accept what is synthesized in factories or produced outside of Earth, whether it is produced on a space farm or on the moon.

In addition to the fact that it is unacceptable, there is also the fact that these produced foods are still being evaluated at this stage, and they will only be developed after it is determined that the foods produced by these methods are harmless to people.

With development, opening up is a matter of time.

「

Well, even though I know that the food produced is safe, I don't want to eat it, I know the devil, but I just feel that it is not safe." Zuo Dajun said, "Seriously, it is a little difficult for our generation to change this view, but the new generation will not have such a mental burden, and they will naturally accept this."

Hearing Zuo Dajun say this, several people nodded.

Fan Xiaoming said: "I won't take the initiative to eat, to be honest, I can accept the food produced in the traditional way of space farm, and the synthetic way is really difficult for me to accept, just like the drinking water filtered out of materials, I know that I can drink it, but psychologically I just can't accept it, the key is to know, if you don't know, it doesn't matter."

Xu Zhengping smiled and said: "Yes, it is really difficult to accept the situation of knowing, in fact, it is just like that, if you accept it, you will accept it, the food grown in the space farm in front of us is now our population is small, and the output of the earth is completely enough for us to eat, but with the development and the increase of population, the output of food on the earth is definitely not enough, so we can only choose the food produced by the space farm or the direct synthesis method."

The earth is so big, and the food it produces is definitely limited.

It is foreseeable that the human population will only increase in the future.

Human beings will be scattered all over the solar system, all over the universe.

At that time, the number of human beings must have been astronomical, and the source of food and food could not have depended on the earth.

In other words, with the passage of time, whether it is a space farm method or a synthesis method, these methods will be accepted and will become the mainstream way.

Zuo Dajun nodded and said, "That's for sure, don't say that the solar system is outside the solar system, it's really going to be fully developed, the human population doesn't know how many times it is now, even if the entire earth is planted with food, it won't be enough for these people to eat, but at that time, the food produced on the earth will be rare, heh! Does this mean that it will be a great honor to be able to settle on Earth in the future, and maybe not a galaxy will be as good as a house on Earth in the future."

Hearing Zuo Dajun's last words, several people looked at Zuo Dajun with strange eyes.

"Dajun, your thinking span is a bit large." Fan Xiaoming smiled and said, "But you are indeed not wrong, after all, the earth is the cradle of our human race, with the development of our human race, the status of the earth will only get higher and higher, not to mention a house on the earth, even a house in the solar system is also priceless, not to mention compared with a star system, it is much more valuable than any planet."

Bao Qi was looking at Zuo Dajun and teased: "Dajun, you can set up a family motto, you can't buy a house or land on the earth, if you really want to buy it, it is estimated that you will come back to the earth to travel in the future, or the kind of time limit, if you don't leave, drive it directly."

"No! This...... It's possible." Zuo Dajun said, "The status of the earth is difficult to replace, at least for a long time, not only the problem of the earth and the solar system, but also the problem of the virtual universe...... This...... In that case, isn't it cheating people to let people emigrate now?"

Fan Xiaoming smiled and said: "It's not a pit person, you can see the relevant regulations of immigration, immigrants are immigrants, and they don't ask to sell the house and land on the earth, speaking of which, now the land on the earth is more valuable than the house, my family has always been an urban hukou, no land, and the current urban living environment can not be compared with the countryside at all, now I am particularly envious of the rural land, especially the kind with mountains, it is very remarkable, as for the land now, it is a thousand difficulties, basically impossible."

Su Zhe, Zuo Dajun, and Bao Qizheng smiled, they all had rural hukou, homesteads and land, while Fan Xiaoming and Xu Zhengping were envious.

Zuo Dajun smiled all over his face, "I really haven't looked at it carefully, anyway, now the homestead and land are a radish and a pit, and there is no way to do it, whether the houses in the city can be bought, as well as immigrants to the moon and Mars, I will stay for a while, then there will be real estate and land, it is beautiful to think about."

"It's beautiful." Fan Xiaoming smiled, "You said that someone would sell it for money now

House, but also buy a house in the city, although there are fewer people living in the city now, but no one wants to sell, I really want to make money, as long as I work hard, the speed of money is very fast, I will say so! There are very few fools in this world, and with this trend, everyone knows that things on earth are rare, let alone houses and land."

In fact, these are no secret on the Internet.

Right now, even if you lie at home, you can live a well-off life, and as long as you participate in work, you can live a rich life.

In this way, who is still going to buy a house because of money, as for the land, it is not allowed.

Speaking of which, there are very few people who don't own a house.

A year ago, those who had a house in the city now regretted their intestines when they moved their hukou to the city, and those who could not afford to buy a house in the city are now secretly happy.

In just one year, those who worked outside the home returned to the countryside and pushed down their old houses to build new houses.

The new house is what you want, and it is built according to the villa worth 100 million in the past.
