"At present, the station where the fleet is located is divided into five major areas and fifty-five districts, of which the central dock area is the core of the entire station, which is mainly responsible for the construction of various ships of the future fleet, and is still being expanded.

"There are also four large areas scattered around the central dock area, namely the scientific experiment area responsible for the progress and teaching of various experiments, the comprehensive smelting area responsible for the collection, processing and deep processing of raw materials, the engineering construction area responsible for the construction of temporary ships and engineering robots, and the material storage area specially used to store finished materials. And the place we are going to now is the scientific experiment area where the Academy of Sciences is located. ”

Moving along the channel of the void, in a small spaceship, Zhou Chen carefully introduced the surrounding layout to everyone.

The "footprint" of the station is large, and it is like a large net spread out in Ganymede's orbit around Jupiter, moving with Ganymede. Along the way, Zhou Chen specially made the spacecraft circle around the entire station, and gave a detailed introduction to each area.

When passing by the comprehensive smelting area and the engineering construction area, everyone on the spaceship was shocked by the hot scene of large-scale industrial construction outside, and the kind of all-mechanical, large-scale construction method is impossible to appear on Earth. Just imagine how incredible it would be for them to think that thousands of tons or tens of thousands of tons of construction can be completed in a single stamping, but it is real in front of them!

There are also delicate robots that are constantly being built in the assembly line, most of them are all kinds of engineering robots with strange shapes, carrying various detectors or knives, shovels, welding and other equipment, but there are also a small number of humanoid privates carrying standard weapons, just like the kind of robots that followed Zhou Chen's side at the beginning! These humanoid soldiers make up only a small fraction of all robots, but their numbers are not to be underestimated.

This was a deep shock to the newcomers, and it also gave them a deep understanding of the force of the Earth Fleet.

After a short time, the small spacecraft docked to the connection position in the scientific experiment area. The crowd stepped out of the small spaceship and entered the inner corridor of the experimental area.

Like the small spaceship, the experimental area also has its own gravity, even if it is an extended pipe gallery, when walking on it, it is like standing on the ground, this kind of gravity feeling is exactly the same as the earth, which makes everyone feel novel.

If you look at the leopard in the tube, you can know a thing or two, the level of technology here is indeed too much higher than that of the earth, and you can clearly feel it from the detail of artificial gravity alone.

"Captain, how does the gravitational effect work here? It's just amazing! ”

A doctor of theoretical physics named Zhuang Xiaohe finally couldn't hold back the doubts in his heart and asked.

The others paused in their footsteps, thinking of the gravity they had felt on the spaceship on the same size as on Earth, how exactly did it work? Everyone couldn't help but be a little curious, so they pricked up their ears one after another.

Zhou Chen was also stunned, and then he smiled, not surprised, because he had also been curious about this question, and he had asked Dandan.

In fact, the problem of gravity has always been an objective obstacle to interstellar voyages, although the feeling equivalent of gravity can be created through rotational centrifugation, but it is actually just a pseudo-gravity, although this method can solve the problem of weightlessness to a certain extent, but in the process of taking this method, it is inevitable that there will be some unadaptability.

And this kind of pseudo-gravity can usually only be implemented for the main large parts, can not be applied to the corners and corners, the obvious example is that the connection link of the spacecraft can not rotate, so these places can not produce pseudo-gravity, and the pseudo-gravity created by choosing centrifugation is also related to the radius of rotation, which leads to the gravity generated in different places towards the axis is also different, and it is a little handy in the process of application!

If the problem of gravity is really solved, wouldn't interstellar voyages become extremely pleasant?

Seeing that everyone was looking at him with curious eyes, Zhou Chen knew that he needed to say why.

He coughed lightly and said confidently, "The reason why we feel gravity is because below where we are, there is a restrained Higgs field everywhere!" ”

"The Higgs field is a field that fills the universe, it is a quantum field, in fact, the current particle theory model believes that there are sixty-two kinds of elementary particles, each of which corresponds to a corresponding quantum field."

"The Higgs field is one of them, which can give mass to matter at the moment when the vacuum symmetry is broken. So by constraining the Higgs field, we can change the mass of the object in the local space range, and then get the gravity we want. ”

At this time, except for Zhuang Xiaohe, who was born in basic theory, who could understand Zhou Chen's explanation, most of them showed a blank look. Although they still have some understanding of what Zhou Chen said about the Higgs field giving material mass, it is limited to that.

"But the gravity generated by the mass given by the Higgs field should also be pseudogravity, right?"

Zhuang Xiaohe raised his doubts.

"That's right, it's indeed pseudogravity!"

Zhou Chen nodded calmly: "There is no way to do this, all the technology of the current Earth Fleet comes from the Odo civilization, but the Odo civilization is only a third-level civilization in the universe, and it is far from the level of discovering the 'graviton', and naturally it cannot solve the principle of gravitational generation." ”

"However, the scientists of the Odo civilization found another way and obtained the desired gravitational effect by restraining the Higgs field."

Many people believe that the magnitude of gravity is directly related to the mass of the object, as if they think that gravity is created because the object has mass. In fact, in the current theory, the factor that produces gravity or gravity is actually the gravitational mass, and the Higgs field should produce the inertial mass.

Gravitational force is only related to gravitational mass, while inertia is only related to inertial mass, they are both intrinsic properties of matter, independent of other properties of matter, such as how much charge it has, how much magnetic charge it has. However, the fact that the gravitational mass is strictly equal to the inertial mass in the experiment suggests that the two masses may be the same thing, but we have not yet found evidence that they are completely identified.

Knowing this, but not knowing why, the principle of gravity generation currently used on the Earth Fleet is actually the last link that equates gravitational mass with inertial mass, which even the Odo civilization has not mastered, so the gravity generated by this method can only be called pseudogravity.

Zhou Chen guessed that this problem could only be completely solved after discovering the "Great Unification Theory", being promoted to a fourth-level civilization, and perfectly integrating gravity into the existing mechanical system. At that time, the Higgs field, the Higgs boson, the inertial mass, the gravitational field, the graviton, and the gravitational mass can be organically combined to form a complete set of interconvertible theories.

"However, by controlling the Higgs field to generate mass, and then distorting the space by the mass effect, giving a certain gravity to the local space, although the gravity generated by this mechanism is still pseudo-gravity, it is much more practical than the pseudo-gravity generated by centrifugation by rotation, at least it can cover all corners of the spacecraft indiscriminately!"

Zhuang Xiaohe looked moved and said with admiration from the bottom of his heart. By controlling the Higgs field, you can get a false gravity effect, what a great technological prowess!

Zhou Chen smiled, and then led everyone to continue to visit the various facilities in the scientific experiment area.

When they came to a huge building, Zhou Chen stopped and introduced to everyone through the special glass: "This is the temporary headquarters of the Academy of Sciences, and this will be the place where everyone will study and work in the future." ”

When everyone heard this, they couldn't help but come forward and take a closer look.

Looking out through the glass wall of the pipe gallery, I saw a huge metal building erected by several giant arms, the metal building was very high, a full 100 stories high, and the volley showed the shape of a crescent moon. At the point of the crescent crescent gap, there is a huge platform of light and shadow, which looks like a giant lecture hall from a distance.

Seeing everyone's surprised expressions, Zhou Chen smiled and said, "In addition to receiving courses related to your major every day, you also have to take one day a week to come here for audio-visual learning of the universe overview. This huge field of light and shadow will be used to present a three-dimensional image of the universe. ”

"Even if it's used to understand the universe, it doesn't need to be that big, right?"

Cai Xiaoxi opened his mouth in shock when he saw the platform, full of shock.

Zhou Chen shook his head and said: "You can't say that, the universe is so big, when the picture is unfolded, you will find that even if it is such a large light and shadow field, sometimes it will be insufficient." ”

"Is that true?" Everyone thought it was incredible.

"I'll see when the time comes." Zhou Chen smiled mysteriously.

Next, he took everyone to visit the location of each research group, this time the recruited scientists were divided into thirteen scientific disciplines, 267 research groups, but only 39 people have come at the moment, so there are still a large number of research groups in a state of vacancies. With such a small number of people, everyone can only be temporarily gathered together.

Bringing everyone to the living area, Zhou Chen casually opened a room and introduced: "This is where you will live in the future, everyone has arranged a separate room, and the living area is connected to the experimental area and the teaching area through the pipe gallery, but you need to verify it with an identity card to enter and exit each area." ”

In order to provide the best service to these scientists, Zhou Chen also struggled in their daily life, not only set up rooms according to the standards of star-rated hotels, but also did not hesitate to equip everyone with an assistant robot.

"If you have any questions in the future, you can ask the assistant robot, and they will tell you the answer."

Talking about a short, flat, cute robot about a meter tall came to the crowd with the help of several wheels that could rotate at 360 degrees.

"Ah, this robot is so cute!!" Everyone's eyes were immediately attracted by this kind of robot, and they all bent down and pointed at the robot, and a few even reached out to touch the head of this kind of robot.
