When Su Zhe and Fan Xiaoming left the Sky space station, they were in the sky over the Americas.

The two of them floated in an orbit at an altitude of 800 kilometers, looking at the sun in the distance and at the land of America.

Fan Xiaoming said with emotion: "Westerners opened the Age of Discovery, thus leading by 500 years, and we opened the Space Age, I don't know how many years we can lead!" ”

"Who can say what will happen in the future?" Su Zhe said, "It's a joke that if aliens with more advanced science and technology discover the earth, maybe they will wipe us humans off the earth." ”

"It's possible, but it's possible." Fan Xiaoming said, "Aliens! I don't think I'll see it in my lifetime. ”

"Not necessarily! Maybe sometime an alien will visit Earth. Su Zhe said.

"Don't! What I want to see is that we take the initiative to discover aliens, not be discovered by aliens. Fan Xiaoming said.

As the two spoke, the main engine of their armored spacesuit started.

After deorbiting, the two of them accelerated their flight with an acceleration of 1.2 G.

While lowering their altitude, the two flew over the land of America and over the Pacific Ocean.

In the second half of the race, the speed of the two continued to decrease.

At this time, the wings of the two armored spacesuits spread, and they continued to receive the illumination of the blue beam.

"Not to mention, after the upgrade of the armored spacesuit, its endurance has been greatly improved, and it only needs to be recharged twice as long as it returns from an orbit at an altitude of 800 kilometers, I believe that it will not be long before you can fly directly into space in an armored spacesuit without charging." Fan Xiaoming said.

"It's impossible to rely on today's super batteries, except with nuclear power." Su Zhe said, "Miniaturized nuclear fission, or nuclear fusion. ”

"This ...... It's hard to achieve. Fan Xiaoming said.

"No matter how hard it is, you have to do it! Leaving aside the issue of miniaturization, if we don't develop controlled nuclear fusion technology, it will be very difficult for us to leave the solar system. Su Zhe said.

The energy source of the pillar project is the sun, and the farther the distance, the more difficult it is to transmit energy.

Relying on the Light Pillar Project to provide energy to explore the universe beyond the solar system is unrealistic.

For now, the most ideal source of energy for exploring the universe is controlled nuclear fusion.

Not only is the energy density high, but the raw material is present in its cosmic space, hydrogen!

"That's true." Fan Xiaoming said, "But there is no rush now, after all, it will take a long time to develop the solar system." ”

"Yes! It's not that urgent, but the research should be on the agenda. Su Zhe said.

The two chatted, and they came to the sky above the Tamu Gobi.

After a while, the two of them stopped smoothly at the test airport.

After changing their clothes, the two of them took a flying car on their way back to their accommodation.

Fan Xiaoming said to Su Zhe seriously: "According to your requirements, a scientific research team of 10,000 people to study the human body has been formed, of which 3,000 people focus on the study of the human brain, what do you think will be arranged next?" ”

The 10,000 people are made up of people from various disciplines, including mathematics, chemistry, physics, biology, medicine, and so on.

Source change app】

Among them, the proportion of people studying medicine and biology is the largest, and the two together exceed half of them.

Su Zhe thought for a while and said, "Let them collect and sort out the past research results on the human body, and take advantage of this time to take a look at these research results to lay a good foundation for our future research." ”

The main purpose of choosing such a topic is to understand the mechanism of the human body and fundamentally solve the problem of human birth, aging, sickness and death.

"Good!" Fan Xiaoming smiled and said, "It's just you, ordinary people can't do this kind of research at all, this is an all-discipline!" For example, I can only do physics, but not biology and chemistry. ”

Su Zhe smiled and said: "To be honest, the current sub-discipline has great drawbacks, once you learn a subject, your thinking is easy to be bound by this subject, and it is difficult to look at the problem with a comprehensive vision, but I have to admit that the sub-discipline reduces the difficulty of learning knowledge." ”

"You say this, you think everyone has the same brain as you! You know, the vast majority of people are ordinary people. Fan Xiaoming said, "But the school can cultivate such talents alone, of course, only real geniuses are worth cultivating." ”

"Yes! You did remind me. Su Zhe said with a smile, "We can hold an experimental class, regardless of discipline, learn everything, and see if we can train scientists with a full perspective." ”

"That's right! Right! It's a good idea. Fan Xiaoming smiled, "Take the study of the human body as an example, it will definitely involve the whole discipline, how can a person like me who is bound by a single discipline to conduct comprehensive research, to say something unpleasant, I don't know some knowledge of chemistry and biology at all, how can I consider the overall situation." ”

"That's right! You don't even know the other person's existence, how do you make a judgment! Su Zhe nodded, "The day after tomorrow, aren't we going to participate in the ceremony of the completion of the permanent base on the moon remotely!" At the end of the ceremony, the principal can have a good chat about the experimental class on the way back to Earth. ”

Fan Xiaoming thought for a while and said, "You won't think about taking this experimental class in person!" ”

"That's what I thought." Su Zhe said with a smile, "However, entering the experimental class requires a certain assessment, to put it simply, not the kind of gifted genius who cannot enter the experimental class." ”

Fan Xiaoming smiled and asked, "Do you think a genius like me can enter the experimental class?" ”

"Do you want me to tell the truth or a lie?" Su Zhe smiled.

"Needless to say, I know the result." Fan Xiaoming smiled with emotion, "Then how many students do you plan to enroll in this experimental class?" ”

"I set an assessment standard, how many people have passed the assessment, how many people will be recruited, if none of them pass, then no one will be recruited." Su Zhe said bluntly.

The two chatted from the flying car to their lodgings.

After chatting about some details in the living room of the residence, the two of them washed and slept after they were basically finalized.

At four o'clock in the morning the next day, Su Zhe and Fan Xiaoming came to the control hall of the test airport early.

Sitting in front of the big screen, looking at the solar energy collection station and the light energy transmission station that are still flying on the big screen.

At this point, both are close to their destinations, and both are slowing down.

As far as the big screen is showing now, the former is five minutes ago, and the latter is fifteen minutes ago.

In a space of 90 million kilometers, the solar collection panels of the solar collection station are half-unfolded.

Its main engine is thrusting back at full force, allowing it to enter Mercury's orbit at the right angle and at the right speed.

Whether it is the control of speed, or into orbit, etc., these are automatically controlled, after all, the distance is too far, and it takes more than ten minutes for the signal to go back and forth.

After the solar collection station was successfully put into orbit, its solar collection panels began to unfold.

In a short time, the solar collection station was in full swing, covering an area of nine square kilometres.

Once fully deployed, the solar collection station was fully operational.

After sunlight hits the solar collection panels, it is converted into a specific wavelength of light through the solar collection panels.

After these specific wavelengths of light are concentrated together, the specific wavelength of light is transmitted to the terminal through a high-power light energy transmission optical cable, which is a light energy emitter, that is, a beam channel generator.

Relatively speaking, the principle of the two is the same, and they can be converted to each other.

But in general, a light emitter is a light emitter, and its main task is the transmission of light energy.

When concentrating specific light on a light emitter, there are usually two options: either disperse the light of these specific wavelengths and return it to space, or emit a concentrated beam in a specific direction so that it is accepted by the light energy transmission station or by the energy user.

Such as space city, all kinds of spacecraft and so on.

At this time, the main part of the collected energy is returned to space, and part of it maintains the operation of the entire solar collection station.

The most important part of this is to power the numerous simplified heavy photonic aerospace engines.

In the case of normal operation of the solar collection station, part of its engine is always in working condition.

The reason for this is to maintain the relative position of the solar energy collection station.

You must know that whether it is a terminal or a light energy transmission station, the distance is far apart.

But light energy transmission is point-to-point, which requires accurate positioning in space, and only in this way can point-to-point light energy transmission be achieved.

Earth, the control hall of the Tamu-Gobi test airfield.

Su Zhe was very Fan Xiaoming looked at the pictures and data that happened nearly six minutes ago on the big screen.

Fan Xiaoming said with some excitement: "Not bad, not bad!" The solar energy collection station has successfully reached its destination, and now it is waiting for the light energy transmission station. ”

"Yes!" Su Zhe said, "The distance is too far, remote control is completely impossible, and it can only rely on automatic control." ”

"No way! That's just the way it is. Fan Xiaoming said, "According to the existing plan, many, many space cities will be built in the solar system, the purpose is to be able to control nearby." ”

"It is still necessary to develop information instantaneous transmission technology." Su Zhe said seriously.

"I also know that it is necessary, but not only does this technology have no basic theory, but with the current theoretical basis, it is impossible to achieve instantaneous information transmission technology." Fan Xiaoming sighed.

Su Zhe nodded and said: "If there is no basic theory, we will study it ourselves, there is no need to treat the current basic theory as a golden order, we can think like this, the current basic theory is imperfect, we need to continue to demonstrate, dare to think before we dare to do, if we say that the speed of light is unsurpassable, then what else to study, go home and farm." ”

The two chatted and looked at the big screen in unison.

On the large screen, the light transmission station has reached its destination, and the beam of light of a specific wavelength with a diameter of 100 meters emitted by the solar energy collection station has been shot in a specific direction.

It displays sixteen minutes of footage and data.

At this time, above the ecliptic plane of the solar system, at a distance of two astronomical units, the light energy transmission station had received a beam with a diameter of one hundred meters.

At about the same time, the light transmission station emitted a beam of light in the direction of the Earth.

Similarly, ninety percent of the light energy received by the light energy transmission station will be transmitted to the terminal or other light energy transmission stations.

The rest of the light energy will keep the light energy transmission station running.

After a sixteen-minute flight, the beam emitted by the light transmission station was extremely accurately illuminated on the light energy receiver in the geosynchronous orbit spaceport.

Almost at the same time, the spaceport and the beam passage on the ground and the moon were built.

Starting from a solar collection station in Mercury's orbit, sunlight of different wavelengths is collected and converted into light of a specific wavelength, resulting in a beam of light with a diameter of 100 meters.

Then, after a sixteen-minute flight, the beam is redirected by the light energy transmission station.

For another sixteen minutes, the beam shone on the spaceport in geosynchronous orbit.

At this point, four screens are displayed on the big screen.

They are a solar energy collection station, a light energy transmission station, a spaceport in geosynchronous orbit, and a beam channel generator in lunar orbit.

Su Zhe and Fan Xiaoming looked at the big screen nervously, afraid that the process of light energy transmission would be interrupted.

Another hour passed, and the process of light transmission remained the same.

At this time, Su Zhe, Fan Xiaoming, and everyone in the control hall cheered.

The fact that this process of light energy transmission can be maintained for a long time shows that the first attempt of the light pillar project was successful.

At the same time, it also indicates that there will be a steady stream of energy used.

Unfortunately, at this stage, these light energy can only be used in the construction of beam channels, as for other uses, it is necessary to wait for the completion of the Sanmen project and the completion of the construction of other domestic light energy receivers.

Even so, it is worth cheering, at least there is no need to supply energy for the beam channel in China, which greatly reduces the burden of domestic energy supply.

But to really solve it, we need to wait a little longer.

Fan Xiaoming looked at the big screen, then looked out of the window that was already bright, and said, "It's done!" Next, you can use the beam channel unscrupulously, you don't need to buckle the rope as before, the materials of the remaining five solar energy collection stations and two light energy transmission stations can be transported, the materials for the development of the moon can also be transported on a large scale, and the probes queuing up to be launched can all be on board. ”

"Yes! Yes! Su Zhe smiled, "Let's go!" Let's have breakfast, let's rest and rest today, and the next period of time will be full, but it's only a month, and when the personnel are trained, we don't have to go on it personally, we can do something else. ”

"Yes! We still have a lot of work to do, and there are a lot of topics that we need to study. Fan Xiaoming's smiling hand.

With that, the two got up and left the control hall.

On the way to the cafeteria, Su Zhe asked, "Don't rest today, isn't the scientific research team that studies the human body formed!" In this way, go back and give them a lecture today, so that they know what the research team is going to study! ”

"This ...... Really don't rest? Fan Xiaoming asked seriously.

"Yes! Rest is also reading a book or something, it is better to give a lecture. Su Zhe said.

"Good! I'll arrange it right away. Fan Xiaoming said, "Then I set the time for this afternoon, the venue is in the school indoor gymnasium, which can seat 10,000 people, and it is often feasible for three hours?" ”

Su Zhe nodded and said, "Okay!" ”
