I! Pretending to Be Reborn, Director of Doomsday Hoax

On the screen, there is a line of big characters.

"If the sun goes out, how will the great Berry Country continue its glory and survive the disaster?"

His outrageous eyes scanned the audience, and finally, his eyes stopped on an old white man with messy hair.

This is Caesar Ein, who once made an important achievement in Einstein's light quantum hypothesis, and is a master of special relativity and general relativity. At the same time, he also realized the "quantum anomalous Hall effect", and won two Nobel Prizes Physics Prize!

Ein is the well-deserved No.1 in the field of human physics after Einstein, and he is called the successor of Einstein. In contemporary times, he is the authority of physics! !

"Professor Ain, you should preside over this meeting." Te Li ordered.

Ain, who was resting with his eyes closed, opened his eyes. The sunken eye sockets contained a desire to explore the mysteries of the universe.

He nodded, got up and walked to the podium.

Looking at the dense crowd under the podium, he was a little moved.

Since he bid farewell to the podium, the old white man had not seen such a scene for many years.

Only this time, it wasn't students sitting under the stage, but countless top scientists with terrifying titles.

His old voice spoke fluent English.

"If the sun goes out, how will our great country of strawberries fight?"

"First of all, I am very puzzled. If the sun in the main sequence stage has no fusion reaction, how can it resist its own gravity? In my opinion, if the sun goes out, the blue star will be destroyed in an instant."

"The only ones that can resist gravity are white dwarfs and neutron stars. Because they all obey the Pauli exclusion principle, they are stars that rely on electron degeneracy pressure and neutron degeneracy pressure to stabilize their existence."

"However, these two kinds of stars are the corpses of stars..."

"In the Dragon Kingdom, there are also top scientists. Professor Zou Botao is one of them that I admire. They must have raised the same question - if the sun goes out and the gravity is lost, the blue star will collapse instantly.

"But they all ended up accepting the theory!"

"I'm curious, what did Director Xu use to convince Professor Zou Botao and the others..."

The audience was extremely dissatisfied with the old physicist's words, and shouted: "Professor Ain, now is not the time to pursue the truth, we need to know how we should survive after the sun goes out!" Ain's words came to an abrupt end Stop, and swallow the remaining few sentences back into your stomach.

He glanced in the direction of Longguo calmly, and his heart became a little more fascinated by Xu Qiu, the mysteries of the universe and the sun.

"I divide the era after the sun goes out into five stages: darkness invasion, energy catastrophe, photosynthesis reorganization, frozen blue star, and extreme life."

Ain sighed.

He has already carried out hundreds of rehearsals of the model of the sun extinguishing, and he also has his own ideas about the doomsday facility in the survival plan.

He took a drag on his cigarette and spoke slowly.

"The first is the age of the Dark Invasion, which is the earliest period of the extinction of the sun, which lasts only a few hours."

"When the sun goes out, the humans on Blue Star will not feel the darkness immediately. After [-] seconds, there is only the last twilight in the sky, the moon disappears, and Jupiter in the distance can still reflect the previous sunlight

99

O

"After about an hour, the last ray of light in the sky also completely dissipates, but it is not pure black, because in the absence of moonlight and sunlight, the universe will become the only visible background!" "according to the brightness of the Milky Way left by bdulAhad Calculate the formula, get the Ahad constant, and finally it can be calculated that the brightness of the Milky Way is about 1/300 of the brightness of the full moon, and it is not completely dark." "Then there is an energy catastrophe!"

"All solar equipment, and energy sources that use solar energy, will fail, and electricity and fossil energy will become the only two energy sources."

"The good news is that as long as the creatures on the blue planet are not extinct, humans can exploit oil and gas resources, and there is no need to worry about energy depletion!"

"After this, photosynthesis is reorganized!"

"90.00% of the natural production on the blue star is closely related to photosynthesis! Therefore, after the sun goes out, if we want to maintain the survival of human beings, we must ensure that photosynthesis works again!"

"The only good news is that human beings consume about 6x10kg of oxygen every year, and the total oxygen content in the atmosphere is about 2x1.2^10 metric tons. We may still consume thousands of years before the oxygen will be exhausted." "But we A problem must be considered, after the sun goes out, the surface temperature plummets, even close to absolute zero, at this temperature, oxygen will be frozen into a light blue solid..."

"So, in fact, we don't have so much oxygen to use. In addition to humans, there are also a large number of insects and microorganisms competing with us. We still have to use high-energy physics and plasma technology to reawaken photosynthesis!"

"What plans do you guys have for resetting the photosynthetic era?"

Ain turned his gaze to the venue.

A scholar who studies full-spectrum natural light stood up and said, "Professor Ain, I think we can create artificial light sources!"

"At present, the bionic technology of full-spectrum natural light has achieved good results, and even a few months ago, we were planning to commercialize full-spectrum natural light!"

"We designed a solar simulator!"

"With the help of a solar simulator, we can simulate the full spectrum of natural light, and restore the proportion of solar radiation bands and light intensity as much as possible." A nano-lab director stood up, and he is also the director of the Global Nanotechnology International Organization director.

"We synthesized a hollow nanosphere!"

"This hollow structure can be catalyzed by visible light to generate hydrogen from water to drive the process, which can then be harvested and used as a fuel."

"Using previous artificial light sources, combined with this nanotechnology, there is the possibility of fuel in the dark, and hydrogen is also a potential fuel source for internal combustion engines and other vehicles, while adding a green solution to previous traditional energy options. !"

Everyone's eyes lit up.

Artificial light sources solve the problem of photosynthesis.

And nanospheres solve the energy problem again!

Ain's mood improved, and he asked, "Is there any other plan?"

Seeing that everyone was silent, he stroked his white beard and said slowly, "I have another idea, artificial leaves."

"We know that photosynthesis is the process by which green plants convert energy from the sun into chemical energy. The photolysis of water, in which water is stripped of electrons and decomposed into protons and oxygen, is the first step in photosynthesis."

"This process occurs in photosystem II. Photosystem II is a photosynthetic unit of plants that contains two light-harvesting complexes and a photoreaction center."

"One of my students once tried to make artificial leaves of semiconductors, but the artificial leaves did not work very efficiently. After some analysis, we noticed that one step in the chemical chain can slow down the whole process, while the fast reaction Must be combined with slower processes, creating a sort of 'bottleneck' effect on artificial foliage productivity..."

"That is to say, neither too fast nor too slow, must simulate natural characteristics, respond quickly and proceed slowly."

"So we took a new approach, using graphitic carbon nitride as a catalyst for photosynthesis."

"This substance is similar to graphene, it is highly stable, and the production cost is very low. We are currently improving photosynthetic efficiency. If successful, this artificial leaf can replace natural leaves for photosynthesis!"

A white biologist stood up when he heard this, stuttering with excitement, and said:

"According to our latest discovery, some photosynthetic organisms can turn green in the dark. Behind this is a possible chemical mechanism of the C17-C18 double bond reduction reaction. That is, DPOR enzyme! Can this replace graphite phase carbon nitride ?”

Ain's eyes lit up, he wrote down this strange enzyme, and planned to let the students experiment next.

"Professor Ain, next, Frozen Blue Star, what era is it again?" someone urged.

o.. ask for flowers...

This is a completely different division method from Xu Qiu's prediction of the scene after the sun goes out.

It is novel!

Ain said with a smile: "Under the sunlight, the average temperature of the earth's surface, including hot and cold regions, is 14 to 15 degrees Celsius throughout the year, which is a very suitable temperature."

"But after the sunlight disappeared, the blue star began to radiate heat exponentially:, and then slowly weakened the radiated heat, so the real threat came - cooling!"

"In a week, the global temperature will be close to zero degrees Celsius. Even in the hottest places, the rivers will not be able to avoid freezing. Our Yellowstone National Park, as well as craters, hot springs and other places, will become a small number of places that are still warm. area."

"80.00% of the blue star's internal heat comes from the earth's core, where the continuous decay of radioactive elements has provided the energy it needs to maintain the temperature at [-] degrees Celsius, and the blue star will only have the internal heat of the earth's core." "This, In fact, we should learn from Bingdang, this small country has quite a lot of experience in utilizing geothermal energy, so we can introduce talents!"

"As far as I know, they have a heat pump. The principle of this thing is similar to that of a heat engine. It uses the temperature difference of the refrigerant under high and low pressure conditions to achieve heating, and at the same time forms an effect of recycling geothermal energy. At the same time, it can also use geothermal energy Thermal energy to generate electricity!"

"Between half a year and ten years after the sun goes out, dewdrops will gradually begin to appear on the surface of the earth, but this dewdrop is not the other dewdrop, and its composition is not water but light blue liquid air."

"Because the continuous reduction in temperature will make the denser gas components in the air more and more dense, and then start to form clouds and sediments such as rain, and then snow."

"So at this time, liquid air is falling in the sky. And this liquid air will be an important supplement for our oxygen! As long as the temperature rises and melts, a large amount of fresh oxygen will be produced!"

"At this time, the blue star will become a frozen ice ball, completely covered in white. The only area with flowing water may be the seabed. There are also a few places that still have life."

"Because ice is less dense than water, it will always float on the surface of the ocean. Ice is a good insulator, so even after hundreds of millions of years of sun extinction, liquid water can still spring up at the bottom of the ocean and be absorbed by the ocean surface." It is protected by the ice above it and heated by hydrothermal vents that heat the Earth's interior."

Ain took a sip of water.

Frozen blue star... If the end really comes, how many people will be able to see such a scene?

He went on to say: "The last stage is extreme life."

"And this may also be the most precious resource that we need to utilize and develop after the sun goes out!"

"No matter whether the sun goes out, how low the surface temperature drops, whether the ocean freezes, whether there is life on the blue star, some extremophiles, such as some acidophilic bacteria, will still do nothing around the hydrothermal vents survival."

"Because they already live in the deep sea, they have long been accustomed to being isolated from the sun. On this land, they occupy the mountains and become kings, rely on themselves, get rid of the photosynthesis that most living things rely on, and develop an unimaginable One chemical energy synthesis!"

"They convert heat, methane and sulfur into the energy necessary for life, which are then eaten by clams and tube worms, and then extremophiles deposit mineral elements back into the hot springs, thus maintaining the integrity of the entire ecological chain and food chain!"

"It's a cycle that excludes sunlight!"

"So when we human beings are racking our brains to survive the extremely cold era when the sun is extinguished, this group of microorganisms will not care about the extinction of the sun at all, and it will not even have any impact on them."

"The microbes around the hydrothermal vents will live as if nothing happened..."

"If, I mean if, we can cultivate, synthesize, and even transform crops that use chemosynthesis, in the era when the sun goes out, they will become new plants, our vegetables, and our rations!" With deep thought, he said: "Professor Ain, according to your statement, in other words, the deep sea is warm and will not be frozen?"

Ain nodded, "Yes, Mr. President."

"Then can we use nuclear submarines to live in the deep sea?"

Ain smiled wryly: "It is theoretically possible, as long as the submarine is big enough, strong enough, and has enough food, then humans can live in the submarine forever."

"But the problem is that it is impossible to build a submarine that can accommodate the entire population of Berries!"

"At the same time, once we enter the deep sea, there will be thousands of meters of solid ice above us, and we may not be able to break through the thousands of meters of ice and return to the ground in the remaining years of human beings... "

"In a sense, the escape method of a nuclear submarine is even more extreme and unreliable than a dungeon!"

Younuo. The submarine development expert said, "My lord, I have to tell you one thing. Even the best submarine soldiers in the US can hardly live in a submarine for more than three months."

"If you stay in the deep sea and stay in a submarine, you will go crazy!"

"In that case, a man driven mad in a submarine would be a more terrifying existence than the severe cold on the surface!"

The hearts of the people were awe-inspiring.

They feel suffocated at the thought of being trapped under thousands of meters of ice, living forever in the dark ocean...

Ain also smiled and said, "If it's a submarine, I'd rather die on the first day the sun goes out."

Te said angrily, "Professor Ain, if you have any ideas, don't keep it a secret."

0 ..

For the research on the extinction of the sun, Berry Country should not have done a deeper and more thorough study than Professor Ain.

This is also the reason why Prof. Ain was chosen to host this conference.
