Milky Way, Orion cantilever.

The human realm faces the side of the cantilevered arm of the constellation Cestilis.

After more than 300 years of continuous transformation.

The technology of the quasi-gravitational field generator has become more mature, not only the energy consumption has decreased, but the unit gravity field strength generated has also increased a lot.

The planetary systems in this region have all been hollowed out, leaving only individual stars, and the surface of these stars has built a few Dyson giants.

Of course, these Dyson megastructures are not completely covered with the type of Dyson balls, but rather 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 making neutron materials in normal times.

In the event of a war, the enemy's high-energy particles are close to the vicinity, and the gravitational field generator on top of the Dyson ring can be activated, creating a super-strong gravitational field with a gravitational strength roughly equivalent to that of a medium-sized black hole.

Of course, the specific strength of the 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, these are all stars, but they can provide different amounts of energy to Dyson's rings.

However, considering the rarity of giant stars, 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 that has been tested so far.

The core of a red dwarf-sized star, a modified quasi-gravitational field generator, can generate the gravitational pull of a black hole equivalent to the mass of 46,000 solars.

The core of the orange main-sequence star, a modified quasi-gravitational field generator, can generate the gravitational force of a black hole equivalent to 98,000 solar masses.

The core of a yellow main-sequence star, a modified quasi-gravitational field generator, can generate the gravitational force of a black hole equivalent to 169,000 solar masses.

A standard medium-sized black hole has a mass of about 100,000 suns.

However, there is a certain difference between the coverage of the quasi-gravitational field and that of a black hole, and I don't know if the technical problem of the human quasi-gravitational field is like this, or the quasi-gravitational field itself.

Even if the quasi-gravitational field of 169,000 solar levels is reached, the force field coverage can only reach the limit of 16.9 light years.

Beyond that, the gravitational field has no way to distort space and capture high-energy particles.

In order to ensure the security of human territory, the Federal Headquarters had to coordinate the various groups to create a special defensive ring in the border area.

The defensive circle is in the same direction, and at least three stellar gravitational shields are present.

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

In the area extending outward from the gravitational defense circle, three layers of early warning are set up.

Ensure that the vast majority of blows will be detected in advance by these three layers of early warning.

After all, the stellar gravitational shield cannot be turned on at all times, which not only wastes serious energy consumption, but also seriously affects the external development of human beings.

Now the gravitational defense circle arranged by human civilization has almost reached the level of impermeability, not only can high-energy particle strikes not be able to enter the core area of human territory, but even those high-speed spaceships cannot enter the interior of human territory at will.

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

Therefore, it is too luxurious to turn on the gravitational shield at all times.

However, the technological development of human civilization in recent centuries has indeed accelerated a lot.

The advent of gravitational technology has brought about an effect similar to that of tactile bypass.

Various groups of human civilization are delving into gravitational technology in the hope of opening up other applications.

For example, the well-known "curvature technology" requires that space distortion can be produced before and after, shrinking space in front and stretching space in the back, so as to achieve the purpose of faster-than-light movement.

Unfortunately, the degree to which curvature technology needs to distort space is far beyond the reach of a quasi-gravitational field generator.

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

However, another app was successful.

That application is gravitational field acceleration technology.

In fact, this technology was not developed by human civilization, but was researched by the intelligent civilization at the beginning.

However, this technology is very weak in the hands of the intelligent machine civilization, because the gravitational field acceleration technology requires a large gravitational source to use the gravitational slingshot principle to increase the speed of the spaceship.

The "big gravitational source" required is the gravitational field at the level of a black hole, but the problem is that black holes are very rare celestial objects, and they are very unevenly distributed.

This severely limits the application of gravitational field acceleration technology.

It wasn't until human civilization developed a quasi-gravitational field generator that this technology regained traction.

Now on the front line of human civilization to open up the outer area of Orion's cantilever, the federal headquarters has organized nearby groups to build 11 "high-speed routes".

These high-speed routes consist of a series of gravitationally accelerated stars that can be accelerated in succession to 45% of the speed of light for a spaceship or spacecraft.

45% of the speed of light, which is already faster than all civilizations known to human civilization.

As mentioned earlier, as the speed of a spacecraft gets closer and closer to the speed of light, the kinetic energy generated by its speed itself will also exponentially increase.

In this case, the faster the spacecraft, the more dangerous it becomes.

Before gravitational acceleration technology, the fastest speed of human civilization's spacecraft was 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 every 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 about by gravitational acceleration technology, researchers from the Science Division and the Ministry of Space Industry racked their brains and finally came up with a completely new solution.

This solution is called the "hourglass solution".

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

Then, with a gravity-like field generator and a magnetic field offset shield, the oncoming asteroid is sucked into the hole in the middle.

This solution not only solves the risk of asteroids and stardust particles hitting the spacecraft along the way, but also turns the inhaled material into an ejection working medium through nuclear fusion and magnetic field confinement, which has the effect of accelerating.

The program allows the spacecraft of human civilization, the potential of its flight speed, to develop to the level of near the speed of light.
