Homo sapiens.

Wang Shengtian is also very thankful for his luck. He did not study artificial gravitational fields, but quark materials.

In an unexpected experiment, he discovered that quarks produced a field similar to gravity under the joint action of special neutrinos and strong magnetic fields.

After in-depth research, it took Wang Shengtian more than 50 years to perfect the artificial generation technology of this pseudo-gravitational field.

"This technology has further potential. At present, this prototype can only generate a gravitational field equivalent to about 7.6 times that of Jupiter. If it can be upgraded to a solar-level gravitational field and the gravity is further adjusted, it may be possible to create some special purpose equipment."

Hearing this, Wade Lewis also thought about it.

Suddenly, footsteps sounded behind the two of them.

Wang Shengtian turned his head and found that it was someone he didn't know, but he could see the identity of the person from the other party's uniform.

"Hello! Dr. Wang! I am Jun Songzi, the head of the Frontier Technology Department of the Federal Military Industry Coordination Department. It is a great honor to meet you."

"Director Du, hello!" Wang Shengtian smiled and shook hands with the other party.

Juniper didn't drag his feet, and cut straight to the point: "Doctor, I'm here today, mainly to represent the federal headquarters to investigate the pseudo-gravitational field generator."

"No problem. If you have any questions, Director Du, just ask."

As a member of the Military Industry Coordination Department, Juniper is obviously more professional than Wade Reeves in the weaponization of technology.

He quickly asked a dozen questions.

For example, the upper limit of this technology, how to enhance it, how to quickly change the frequency and so on.

According to Wang Shengtian's description, if a star is considered as the energy core of the pseudo-gravitational field generator, the upper limit of its gravitational field strength can even reach the level of a medium-sized black hole.

And because this is an artificial gravitational field, the frequency change of this gravitational field is relatively simple.

Juniper and several colleagues asked Wang Shengtian while discussing how to weaponize it.

First of all, the idea of ​​using a super-strong gravitational field to tear apart enemy planets or space battleships is definitely not advisable.

Because the enemy will definitely not stay in one area rigidly, and because the pseudo-gravitational field generator needs stars as the energy core, the speed of its own movement must not be much faster.

Considering these problems, as a weapon to directly attack the enemy, the quasi-gravitational field generator is definitely not suitable.

Soon among the colleagues of juniper berry, someone thought of an application direction.

"Your idea is to use the pseudo-gravitational field generator as a defensive shield?" Juniper quickly calculated in his mind.

Others are also thinking about the possibility of this application direction.

The man explained: "If the gravitational strength of the quasi-gravitational field generator can reach the level of a medium-sized black hole, it means that this gravitational field can distort the approaching light and high-energy particles."

"It can indeed be done." Wang Shengtian said it was feasible.

The man continued to explain: "Now the enemy's threat to our homeland is mainly the high-energy particles emitted by the particle cannon. Although the number of natural black holes and neutron stars is huge, covering this territory is obviously a drop in the ocean."

Juniper nodded: "You are right. If a group of pseudo-gravitational field generators can be placed in the border area, it can actually distort incoming high-energy particles."

But Wade Reeves, who was silent on the side, suddenly reminded: "Everyone, you seem to have forgotten another problem. The gravitational field can be distorted and even attract high-energy particles, but the generator itself is not a neutron star or a black hole."

Hearing this reminder, Juniper and the others immediately reacted.

Indeed, as Wade Reeves said, the pseudogravitational field generator itself is not an indestructible neutron star or black hole. Once hit by high-energy particles, the entire device may be scrapped instantly.

However, Juniper suddenly remembered something, and his face suddenly showed a trace of confidence: "Observer Levi, thank you for your reminder, but don't worry, we have found another solution."

"Oh? Could it be another new technology?" Wade Lewis, who was very interested in new technologies, suddenly became interested.

Juniper didn't hide it either: "It's not a new technology, but this technology can play a very good role in conjunction with the pseudo-gravitational field generator."

Then Juniper explained the solution to everyone, which is a technology developed by another group.

Named "Stellar Freeze Shield Technology", it uses multiple layers of materials to form an absolute zero shield that can effectively block high-energy particles.

But this technology has a fatal shortcoming, that is, the area of ​​the absolute zero shield is very small, and there is no way to let the enemy's high-energy particles hit the absolute zero shield.

Obviously this technology is a tasteless.

But juniper has already thought of how to solve the shortcomings of the absolute zero shield, that is to use the pseudo-gravitational field generator to attract high-energy particles to the absolute zero shield.

In this way, the pseudogravitational field generator can attract high-energy particles, and the absolute zero shield can consume the energy of high-energy particles.

In addition, the absolute zero shield itself can also be equipped with a heat recovery system, which can recover and reuse the energy generated by high-energy particles hitting the shield.

Therefore, these two systems can be combined to block the enemy's particle cannon from the human territory.

Chapter 7 and Four Hourglass

Milky way, Orion cantilever.

The Human Territory faces the side of Andromeda's cantilever.

After more than 300 years of continuous transformation.

The pseudo-gravitational field generator technology has become more mature. Not only has the energy consumption decreased, but the strength of the pseudo-gravitational field per unit has also increased a lot.

All the planetary systems in this area have been hollowed out, leaving only individual stars, and on the surface of these stars, there are not a few Dyson giant structures.

Of course, these Dyson megastructures are not fully covered Dyson spheres, but Dyson rings.

Through the Dyson ring, human civilization can continuously extract the energy of stars, and most of this energy is invested in the industry of manufacturing neutron materials in normal times.

If a war breaks out and the enemy's high-energy particles approach nearby, the quasi-gravitational field generator on the Dyson ring can be activated to generate a super-strong gravitational field whose gravitational strength is roughly equivalent to that of a medium-sized black hole.

Of course, the specific strength of the quasi-gravitational field depends on the mass of the star.

For example, white dwarfs, red dwarfs, orange main-sequence stars and yellow main-sequence stars, as well as rare giants, blue giants, and blue supergiants, are all stars, but the energy they can provide to the Dyson ring is different.

However, considering that giant stars are relatively rare, most of the stars transformed by human civilization are mainly red dwarfs, orange main sequence stars and yellow main sequence stars.

According to the data tested so far.

The red dwarf-level stellar core and the modified pseudo-gravitational field generator can generate a black hole gravity equivalent to 4.6 solar masses.

The transformed pseudo-gravitational field generator in the stellar core of the orange main-sequence star level can generate the gravity of a black hole equivalent to 9.8 solar masses.

The modified pseudo-gravitational field generator in the yellow main-sequence star-level stellar core can generate the gravity of a black hole equivalent to 16.9 solar masses.

A standard medium-sized black hole has a mass of about 10 suns.

However, the coverage of the quasi-gravitational field is somewhat different from that of black holes. I don’t know whether it is the technical problem of the quasi-gravitational field or the quasi-gravitational field itself.

Even if the quasi-gravitational field reaches the level of 16.9 suns, the coverage of the force field can only reach the limit of 16.9 light-years.

Beyond this range, the pseudogravitational field has no way to distort space, nor can it trap high-energy particles.

In order to ensure the safety of the human territory, the Federation Headquarters had to coordinate with various groups to draw up a special defensive circle in the border area.

The defense circle is in the same direction, and at least three stars must be guaranteed to have gravitational shields.

At the same time, in order to ensure that these stellar gravitational shields can detect incoming strikes in advance, the federal headquarters coordinated with various groups to form a special Orion cantilever early warning system.

In the area extending outward from the gravitational defense circle, three layers of warnings were set up.

Make sure that most of the blows will be detected in advance by these three layers of early warning.

After all, it is impossible to turn on the stellar gravitational shield all the time. Doing so will not only waste energy consumption, but also seriously affect human's external development.

The gravitational defense circle set up by human civilization has almost reached the level of airtightness. Not only can high-energy particle strikes not enter the core area of ​​human territory, but even those spaceships traveling at high speeds cannot casually enter the human territory.

Even if human civilization is willing, even passing planetary systems or neutron stars can be pulled and guided by gravitational shields.

Therefore, turning on the gravitational shield at all times is really too extravagant.

However, the technological development of human civilization in the past few hundred years has indeed accelerated a lot.

The emergence of gravitational technology has brought about an effect similar to analogy.

Various groups of human civilization are deeply researching gravitational technology, hoping to develop other applications.

For example, the well-known "curvature technology", this technology is required to produce front and rear space distortion, the front shrinks the space, and the back stretches the space, so as to achieve the purpose of superluminal movement.

It's a pity that the degree to which curvature technology needs to distort space is far beyond what a pseudogravitational field generator can handle.

At this stage, human civilization can only do theoretical verification first, and even the prototype of the curvature engine cannot be produced.

However, another application did succeed.

That application is gravitational field acceleration technology.

In fact, this technology was not developed by human civilization, but was developed by omnic civilization.

But this technology is very tasteless in the hands of omnic civilization, because the gravitational field acceleration technology requires a large gravitational source, so that the principle of gravitational slingshot can be used to increase the speed of the spaceship.

The "large gravitational source" required here is a black hole-level gravitational field, but the problem is that black holes are very rare celestial bodies, and the distribution is very uneven.

This severely limits the application of gravitational field acceleration technology.

It was not until human civilization developed a pseudo-gravitational field generator that this technology regained attention.

Now, at the front line of human civilization developing the outer area of ​​Orion’s cantilever, the Federation Headquarters organizes the nearby groups, and builds 11 “high-speed air routes”.

These high-speed routes are composed of a series of gravitationally accelerated stars, which can increase the speed of space battleships or spaceships to 45% of the speed of light through continuous relay acceleration.

45% of the speed of light, this speed has surpassed all civilizations known to human civilization.

As mentioned before, when the speed of the spacecraft is getting closer and closer to the speed of light, the kinetic energy brought by its speed itself will also show an exponential increase.

In this case, the faster the spacecraft, the greater the danger.

Before there is no gravitational acceleration technology, the fastest speed of the spaceship of human civilization is about 24% of the speed of light.

Now it is almost doubled, and the kinetic energy brought by its speed has increased by hundreds of thousands of times.

Obviously, the super magnetic field offset shield used before has no way to withstand this kind of collision.

The application of each new technology is often accompanied by a series of technological changes.

The same is true for gravitational acceleration technology.

In order to adapt to the extreme speed brought by the gravitational acceleration technology, researchers from the Science Business Department and the Space Industry Department racked their brains and finally came up with a brand new solution.

This set of plans is the "hourglass plan".

The so-called hourglass plan, as the name suggests, is to transform the shape of the spacecraft into a shape similar to an "hourglass".

Then cooperate with the pseudo-gravitational field generator and the magnetic field deflection shield to suck the oncoming asteroid into the hole in the middle.

This solution not only solves the risk of asteroids and stardust particles colliding with the spacecraft along the way, but also can transform the material sucked into the loophole into jet working fluid through nuclear fusion and magnetic field confinement, which can accelerate the effect.

This program allows the spacecraft of human civilization to develop its flight speed potential to a level close to the speed of light.

Chapter 7 and Five Star Sirius

Of course, the hourglass scheme combined with gravitational acceleration can theoretically increase the speed of the spacecraft to near the speed of light.

But "theoretically", the word itself is the result of the ideal state.

Many researchers in the Science Division have analyzed the conditions for reaching near-light speed.

First of all, the stellar nodes accelerated by gravitational force must all be composed of blue supergiant stars, so that the gravitational strength can push the spaceship to near the speed of light.

And the number of stellar nodes of this level needs to be at least 3.

Blue supergiant stars are rarer than black holes and neutron stars in the universe. Where can human civilization find 3 blue supergiant stars in a row?

Isn't this embarrassing my fat tiger?

All right!Even if the luck of human civilization is against the sky, and a series of 3 blue supergiant stars are just found, there is no way for human civilization to transform it!

Building a Dyson ring around a blue supergiant?

The resources that need to be consumed, even the human civilization that controls tens of millions of planetary systems, feel scalp numb.

And this is just one small problem.

Another problem is the material problem of the spacecraft.

Why on the high-speed route of human civilization at this time, the limit speed of the spacecraft can only reach 45% of the speed of light?

The answer is not only that the energy level of the gravitational field accelerated by the gravitational acceleration of stars is not enough, but also an important reason is that the current materials of human civilization can only withstand the limit speed of 45% of the speed of light. If the speed exceeds this speed, the spaceship will disintegrate in minutes.

As the speed of the spacecraft becomes faster and faster, various restrictions begin to appear on the materials and structure of the spacecraft itself.

Many people say that spaceships in the cosmic era do not require much shape. As long as the dynamic balance is done well, even a cube shape can be used as a spaceship shape.

This statement is actually limited to just entering the cosmic era, and the speed of the spaceship has not broken through the stage of 1% of the speed of light.

For human civilization, whose travel speed has reached 45% of the speed of light, the appearance of the spacecraft has become more and more important.
