Start sweeping the universe by rubbing the CPU with your hands.

Vacuum, especially the vacuum inside galaxies, is not as "empty" as people understand it.

For example, the original Earth was already in the vacuum category that people understood at a distance of 600 kilometers from the surface. A large number of near-Earth satellites operate at this altitude.

But here, the average particle density can also be as high as tens of billions of particles per cubic centimeter.

Farther away again and reaching interplanetary space, the particle density will decrease to only a dozen per cubic centimeter.

Moving to interstellar space, the particle density is even lower. In intergalactic space, the particle density can be reduced to less than one per cubic meter.

But even such an empty space still cannot meet the vacuum required for this experiment.

Because this is an attempt to influence space through dark force particles. Any excess particles in space may have a weak impact on the curvature of the space, causing the experiment to fail.

To this end, scientists had to develop a new vacuum pump to directly reduce the number of particles in this huge experimental equipment to an average of only 100 particles per 2 cubic meters.

In addition, in order to prevent particles in the test pipe from diffusing into the test space, strong magnetic field restraint equipment has been specially developed to add a "protective film" to the test pipe to strictly prohibit any particle diffusion.

At this moment, in addition to extremely few matter particles, there are only neutrinos, vacuum fluctuation particles, gravitons, dark matter particles, etc. left in this pipeline.

Han Yang currently has no way to clear these particles. Fortunately, these particles will not have much impact on the experiment and are within the acceptable range.

At this moment, a specially developed piece of equipment arrived at one end of this huge pipe. With the effect of its own equipment and the influence of external equipment, the next moment, the space around it was curved extremely precisely according to the program requirements, and the equipment became invisible in an instant and disappeared from people's sight.

The next moment, just 0.033 microseconds later, it appeared again.

It's like teleporting, it was still 100 kilometers away at the last moment. At this moment, it appeared here.

After calculation, people immediately confirmed that in this experiment, its speed reached 2997954559 meters per second, which is equivalent to the speed of straight space!
This speed is 10 times the speed of light, which is 29979 meters longer, about 30 kilometers per second!

A speed of 30 kilometers per second is really insignificant for a level four civilization, let alone compared with speeds up to ten times the speed of light at this moment.

But everyone can clearly know in their hearts that although this breakthrough is small, it is a qualitative breakthrough.

The theoretical speed limit of a Level 4 civilization is ten times the speed of light. At this moment, we have exceeded this limit!
Just like a long time ago, human civilization first transmitted a signal through radio.

This is a small step up in speed. But in the context of the entire theoretical system and background, this is undoubtedly a big step, a huge step.

In terms of speed, a breakthrough has truly been achieved here.

Later, breakthroughs were also made in the dark force shield.

After research, human scientists discovered that the so-called dark force shield is not actually like an excited state shield or a gravity shield, which uses energy or some kind of force to defend against external attacks.

To be more precise, the dark force shield can barely be called a "space" shield.

Through the deep application of darkrons, people will be able to use darkrons to create a layer of distorted space-time around the spacecraft. Through this distorted space-time, any mass and energy that tries to pass through this layer of shield - no matter it is Kinetic energy projectiles, guided weapons, or radiant energy weapons, such as laser beams, radiation beams, etc., distort and neutralize the energy.

However, the dark force shield cannot resist gravity. Because in terms of properties, gravitons are fundamentally different from other particles.

But even if it can't resist, it doesn't matter much. The most important thing is to install some gravity generating and shielding equipment internally. The technology of gravity shield has been deeply understood as early as the fourth level civilization, and now it just needs to be strengthened again.

In addition to protective shield technology, the weapon system has also undergone comprehensive innovation at the fifth-level civilization level.

In addition to the competition for long-distance communication technology, similar to "electronic warfare", in terms of weapons that mainly act on spacecrafts, battleships, bases, ground facilities and other man-made objects, the fifth-level civilization will have a brand-new secret weapon system .

Its basic principle is still based on the application and manipulation of dark particles.

Through the influence of anarkons on space, a fifth-level civilization can even create a weapon that can give a designated space a certain curvature and then instantly restore it to straightness. Therefore, the matter that is distorted along with the distortion of space will instantly lose its structure along with the change in the curvature of space. From the outside, it looks like it was suddenly distorted by a pair of invisible hands.

The impact of the curvature of space can even affect the particle composition of macroscopic matter, causing it to lose its stable structure in an instant, causing spontaneous nuclear fission and nuclear fusion, which in turn triggers violent radiation from the microscopic level, which can affect living things in an instant. Cause huge damage, even kill it directly.

There is also a more complex weapon that currently only exists in the theory of human civilization. People believe that when the understanding of dark force particles is deep enough and the control is deep enough, people can even make a designated space have several different distortion modes.

Just like a pencil, one end rotates clockwise and the other end counterclockwise.

What will happen? Obviously, this pencil will break instantly. From the outside, it looks like it was cut off by an invisible knife in an instant.

With the breakthrough of the dark force theory, one after another theoretically feasible and imaginative weapon systems were dreamed up by military experts, and then entered the stage of actual verification.

At this stage, weapons systems that prove unfeasible are abandoned. Those that are feasible will be retained. Then, on this basis, military theorists began to think and study the five-level civilization combat model.

The short hundred years passed quickly. After that, it was time for the human fleet to set sail again.

People reluctantly left this galaxy and continued to rush to the next anchorage.

During this process, people started theoretical research again and accumulated experimental requirements for the next docking.

More than a hundred years later, the fleet anchored again.

Different from the last parking, this time the various technologies developed based on the dark force theory began to be put into limited practical application.

People are trying to use quark fission-fusion dual reactors to replace the single fission reactors in the past to achieve 100% conversion of matter into energy;
People are trying to install new hyperlight engines on spacecraft and try to get them to achieve higher speeds;
People are trying to build a new shield system, applying it to experimental spacecraft, trying to build a new, anti-interference, long-distance communication system, and developing equipment that can interfere with the other party's communication system...

Time passed quickly, and this time a hundred years also passed quickly.

In this hundred years, for ordinary people living in residential spaceships, in addition to the news media reporting all day long about where and where great breakthroughs have been achieved, what new technologies have we mastered? , daily life has not actually changed. Everything is still familiar.

But for people in the scientific community, this century has brought profound changes to human civilization as a whole.

Because scientists have been working hard for hundreds of years and finally have achieved practical results at this moment.

It was a huge spaceship.

It is a huge spacecraft with a maximum length of 3000 meters, a maximum width of 800 meters, and a total mass of more than 300 million tons.

This spaceship looks extremely ugly, with potholes and undulations everywhere. The armor on it looks like randomly laid boards, one piece here and one piece there. Even its overall shape is like an irregular stone, without any sense of beauty.

But such a spacecraft, in the eyes of the tens of millions of scientific researchers involved in this project, is full of inexplicable attraction like a peerless beauty. Some old scientists even burst into tears after actually seeing it.

Because this spacecraft was not manufactured in an industrial or assembly line manner. In a sense, it is completely customized, completely handmade, and assembled piece by piece in the laboratory.

That's why it's so ugly. Because people at this moment have no time to consider aesthetics at all, as long as the function can be realized.

This ugly spaceship inherits all the most advanced technologies of human civilization so far.

Fission-fusion dual reactor, highly reliable long-distance communication system, dark force-gravity multi-layer shield, dark force hyperlight engine, dark force distortion weapons, dark force radiation weapons, space tearing weapons...

Etc., etc.

Its speed even reached an unprecedented maximum of fifteen times the speed of light.

Based on this, it will also take on an extremely important task when it sets sail this time.

It will set sail together with the human fleet and arrive at the next parking galaxy scheduled by human civilization about 26 years in advance. It will start construction there in advance and prepare the bases, equipment, energy plants, etc. needed for subsequent experiments, waiting for people. 's arrival

By then, people will no longer need preliminary preparation work and can directly start follow-up research.

At the same time, this voyage is also a comprehensive test of this brand-new spacecraft. People will comprehensively study its operation, find modules that need improvement or new design, and optimize it as much as possible to improve its performance again.

As usual, after cleaning up all traces left in this star system, the human fleet set sail again.

Contrary to expectations, in the end, this brand-new spacecraft arrived at the next target galaxy only ten years ahead of schedule.

The reason for the delay was that there were too many unexpected failures inside the spacecraft. Several times, out of desperation, people could only temporarily break away from the super-light speed voyage and repair it during normal navigation, so that it could continue this journey.

However, even if it is only ten years ahead of schedule, it is still enough for Han Yang to use the facilities on it to carry out too many preliminary preparations and save time for subsequent research.

And, even if there were frequent twists and turns, one thing that is undeniable is that it finally reached its destination. And as long as it can reach it, it means that this experiment has been a great success.

A new round of research and improvement began again.

This time, after a hundred years, a brand-new warship with a speed of 50 times the speed of light came to a successful end for people's hard research.

As the theoretical research on dark energy deepens and various applications become more mature, Han Yang and the ruling committee members finally made up their minds after careful discussions.

It’s time to iterate and upgrade the human fleet as a whole.

This time, the human fleet was parked in the galaxy for a full 260 years.

In this process, all mankind once again burst out with vigorous enthusiasm for construction. In addition to regular material collection and scientific experiments, people have also built countless factories and produced spaceships one after another that are truly at the fifth level of civilization.

These include 50 brand-new residential spaceships, up to 100 million level five civilization-level warships, large space carriers, and countless scientific research ships, transport ships, industrial ships, passenger ships...

Each of these newly built residential spaceships has a length of 30 kilometers, a width of 10 kilometers, and a height of 8 kilometers. The interior is divided into floors every 200 meters, for a total of 40 floors.

In addition to the space occupied by the spacecraft equipment, a residential spacecraft can provide up to 6000 kilometers of living space inside, which can accommodate million people in extreme cases.

Of course, the population density under normal circumstances is far from being so high. Under normal circumstances, there are about 150 to 300 million people living in a residential spacecraft. The total number of 50 ships can easily accommodate the current total population of about 9000 billion.

Moreover, each of these residential spaceships is equipped with a corresponding weapon system, has multiple dark force-gravity shields, and is equipped with a dark force hyperlight engine that can sail at 50 times the speed of light.

What is particularly worth mentioning is that the garbage disposal center that was required in every spacecraft in the past and occupied a large space has been completely eliminated in the new residential spacecraft.

Because people no longer need to deal with garbage.

This certainly does not mean that people will no longer produce garbage - a spacecraft with a population of 200 million will produce a huge amount of garbage every day.

Instead, all this garbage was transported to the fission-fusion dual reactor and "burned" as energy.

Feces, waste paper, kitchen waste, dead branches and leaves, rags, and even extremely dangerous biological waste produced in hospitals, radioactive waste produced in laboratories, highly toxic waste produced by chemical research institutes... …

It doesn't matter.

From the perspective of the fission-fusion dual reactor, no matter what comes here, it is mass and will be converted into energy, and then extends to every corner of the spacecraft, becoming lighting, warm air, and calculation needs Electricity becomes the wind, rain, thunder and lightning in the atmospheric circulation system, becomes the energy source to propel the spacecraft forward, and becomes a shield against external aggression...

After completing the change of clothes, a new round of sailing is about to begin. (End of chapter)
