Chapter 703 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 the gravitational acceleration technology, the fastest speed of the spacecraft of human civilization was only 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.
