Because the acceleration of the spacecraft is constant during the driving process, it is equivalent to the existence of stable gravity, except for the need to sit on a chair when the spacecraft has just left the "South Tianmen" space station, and then it can move freely.

However, it was already night when they set out from Earth, and after 5 hours, it was almost equivalent to a night without sleep.

So Tianhuo and He Ruiyin both unfolded their chairs into a bed, and then lay down to rest.

Lu Ze realized his dream of entering space a hundred years ago, and now he is in good spirits, so he has to sit alone in a daze.

At this time, Lu Li suddenly appeared in front of him, and as soon as he appeared, he shouted: "I can't stand it, this delay is too big." ”

"What's wrong?" Looking at Lu Li, who appeared in front of him again, Lu Ze asked helplessly.

"I'm playing a game, and the sudden delay just became so big." Lu Li complained.

Then she noticed her surroundings: "I see, because it's far away from the earth, is there a delay?" ”

Humans are still unable to communicate faster than light, and as they get farther and farther away from Earth, the delay in connecting them to the Star Spirit Network in the spaceship will also increase, and although they can still get information from the Star Spirit Network, they can't interact with others in the virtual world.

Lu Ze understands Lu Li's depression, he has also played some online games more or less before hibernation, and knows how abhorrent latency is.

Fortunately, all the computing equipment in this spaceship is self-contained and can temporarily form a small star spirit network, and Lu Li's quantum black box Lu Ze is carried with him, and there will be no delay in the communication between the two, otherwise Lu Ze will have to wait for 2 seconds before answering, which would be too depressing.

"Why did you run away alone?" Lu Ze asked.

Lu Li glanced at Tianhuo, who was sleeping soundly, and said, "This woman is too dangerous, I want to stay away from her." ”

Although Tianhuo's joke at that time made Lu Ze also embarrassed, he still said: "She was just joking." There is no malicious intent. ”

Lu Li said: "It's terrible because there is no malice, if there is malice, as long as we ignore her, don't we?" ”

Lu Ze said: "Well, you don't have to be so shy at all. When you run like this, doesn't it seem that there are no three hundred taels of silver here? ”

"Hmph, you're kidding me too." Lu Li said angrily.

Lu Ze smiled and said, "You just care too much about what others think of you." You are unique, whether others agree with you or deny you, you are always yourself. ”

"Oh." Lu Li lowered his head and whispered.

Lu Ze changed the subject: "Then do you know anything about the 'Heavenly Palace'?" ”

Lu Li nodded: "During the time you were learning the human language, I already knew a lot about this era, so I suggested that you go to the 'Heavenly Palace' to have a look." Although the earth is the cradle of human civilization, if human beings live on the earth forever, no matter how advanced science and technology are and how comfortable the illusion of the earth is, they will always be just babies who have not left the cradle. The living conditions of the 'Heavenly Palace' may not be as good as those of the earth now, but this is the first step for mankind to truly step out of the cradle, and it is the beginning of mankind's toddler in the universe. It represents the future of humanity, from which humanity, a civilization that may one day spread across the galaxy, began. ”

Lu Ze said: "Can you give me a detailed introduction?" Including the origin of the Heavenly Palace, these. ”

Lu Li said: "This introduction is too complicated, and we have to start with the development of the moon, so I can't explain it to you clearly." When I learned this knowledge before, I recorded the process of understanding the knowledge, why don't you try the synchronous learning method? ”

Lu Ze immediately said happily: "Great." ”

It was because he couldn't use the synchronous learning method that he had been delayed in learning human language for two months, and he had wanted to give it a try.

So Lu Li turned on the synchronous learning system that Alice had encapsulated into the quantum black box, and asked Xinglingwang to transmit the information to Lu Ze's brain in the order in which she had learned this knowledge before.

With the help of the synchronous learning system, Lu Ze only felt that he had become a super genius, and he could understand any knowledge in an instant, this way of learning was so cool that he couldn't stop at all.

The speed of learning is really fast, and it was estimated that it would take about an hour to learn the amount of knowledge, but now it only takes 20 minutes to fully understand.

For the development of the space industry starting from the moon, Lu Ze soon had a clear understanding.

The surface of the moon is not as barren as it once was.

The first is the various large-scale mining and smelting facilities that can be found on almost the entire surface of the moon, which are the basis of the human space industry.

Since the name is "space industry", of course, it is impossible to build everything on Earth and send it to space.

The purpose of the development of the space industry is to establish an industrial system that can completely independent of the earth, and ultimately realize the return of the earth.

It's not complicated to build this infrastructure, all humans have to do is send the most basic gathering and smelting facilities and the most important fusion power stations to the moon, plus robots that can replicate themselves and complete various tasks, so that production on the moon can continue to expand, and eventually the entire moon will be transformed into a factory.

Whether it is the "Tiangong" space city or the "Nantianmen" space station, they are all made by using materials on the moon.

Just one "Nantianmen" space station has a mass of hundreds of thousands of tons, and even if all the earth's space elevators are added together, it will take half a month to transport so much mass into space.

And there are twelve more such space stations.

This is one of the results of the space industry feeding back to the planet.

In addition to these industrial infrastructures, hundreds of laser base stations have been built around several helium-3 fusion power stations, which are built on the surface of the moon to continuously emit lasers to deliver energy to spacecraft that travel between the Earth and the Moon or between the Earth and other planets in the solar system.

However, these spacecraft are not usually completely powered by lasers, and the various electronic devices in the spacecraft are powered by nanobatteries, which can also provide energy to the thrusters when necessary.

There are also many large-scale research facilities on the moon, including the "Yao 4" observatory that Lan Ye mentioned at the Star Spirit Network Conference.

Yao-4 is a huge optical telescope that can observe the planets surrounding all stars in the entire Milky Way, and it is the highest-resolution optical telescope in human history.

The Yao-5 Observatory, which is currently under construction, is the most sensitive radio telescope in human history, with a diameter of 120 kilometers alone.

Although the huge space telescope with an aperture of 120 kilometers has not yet been fully built, it now has a small white spot on the moon that can be seen with the naked eye on Earth.

When Yao 5 is completed, it will be mainly used to search for extraterrestrial civilizations.

If it is true, as Araiya said, there are many extraterrestrial civilizations, but they all eventually perished because they could not break through the bottleneck of controllable nuclear fusion technology, then as long as it is an extraterrestrial civilization within the galaxy and has developed into the information age, the "Yao-5" radio telescope can receive the electromagnetic wave information emitted by the activities of these extraterrestrial civilizations.

At the same time, using very long baseline interferometry technology, Yao-5 will also form a giant telescope with an aperture equivalent to the distance from the Earth to the Moon from the radio telescope on the Earth, which will be used to observe and study dark matter and dark energy in the universe.

However, of all the large research facilities on the Moon, the most well-known is undoubtedly the Circumlunar Particle Accelerator, which is also still under construction.

Through the synchronous learning method, Lu Ze instantly understood the complex formulas involved in the particle accelerator and the reason for building the Circumlunar Particle Accelerator.

Charged particles that reach relativistic velocities produce synchrotron radiation and lose energy when they turn a corner.

In order for the power of synchrotron radiation to remain constant, the radius of the accelerator must increase by the square of the energy of the particle, that is, in order for the particle to obtain twice the energy that the particle can obtain in the accelerator, the radius of the accelerator must be increased by four times.

However, even if the object of acceleration is protons, the circumlunar accelerator has almost reached the theoretical limit.

At the same speed, the more massive the particle loses less energy due to synchrotron radiation, so only proton accelerators generally use annular orbits, and electron accelerators use linear orbits.

If the distance is longer, the proton ring accelerator will lose to the proton linear accelerator like the electron accelerator.

This distance is about twice the distance between the Earth and the Moon.

Lu Ze couldn't help but blush when he learned this, and in a science fiction novel he had written before hibernation, he described a kind of circumsolar particle accelerator that orbited the entire sun. Now he knew that this circumsolar particle accelerator was not realistic at all, except for looking cool, and the fundamental laws of physics dictated that such a long linear accelerator is more suitable than a ring.

The Circumlunar Particle Accelerator was established under the leadership of the "Pioneer House" to study some of the ultimate questions of the universe, such as what was the beginning of the universe? Why is the universe the way it is today? What does a high dimension look like? Wait a minute.

In addition to these, there are weapons on the surface of the moon that are capable of completely destroying the ecological environment on the earth's surface ten times.

These weapons are not intended for war, but to intercept meteorites and prevent them from causing damage to these lunar facilities.

A hundred years ago, there were many science fiction novels or movies that described an asteroid flying to Earth and bringing the end of human civilization. However, in this era, there is no need to worry at all, because these interceptor weapons placed on the lunar surface are enough to change the orbit of the asteroid.
