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

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

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

First of all, the gravitational acceleration star nodes must all be composed of blue supergiants, so that their gravitational strength can push the spacecraft to nearly the speed of light.

The number of star nodes of this level needs to be at least 30,000.

Stars like blue supergiants are rarer than black holes and neutron stars in the universe. Where can human civilization find a series of 30,000 blue supergiants?

Isn't this embarrassing me, Fat Tiger?

All right! Even if human civilization is extremely lucky and happens to find a series of 30,000 blue supergiants, there is no way for human civilization to transform it!

Building a Dyson ring around a blue supergiant star?

The resources required to consume this would make even a human civilization that controls tens of millions of planetary systems feel numb.

And this is just one of the small problems.

Another problem is the material problem of the spacecraft.

Why is it that on the high-speed routes of human civilization at this time, the ultimate speed of 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 star's gravity is not enough, but also an important reason is that the current materials of human civilization can only withstand the ultimate speed of 45% of the speed of light. Beyond this speed, the spacecraft will disintegrate in minutes.

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

Many people say that spaceships in the cosmic era do not have high requirements for appearance. As long as the dynamic balance is done well, even a cube shape can be used as the shape of a spaceship.

This statement is actually limited to the time when the universe has just entered the era, and the speed of the spacecraft has not exceeded the 1% stage of the speed of light.

For human civilization whose sailing speed has reached 45% of the speed of light, the appearance of spacecraft has become increasingly important.

For example, this time, in order to adapt to the soaring speed of the spacecraft, the shape of the spacecraft was designed into a sphere, and an "hourglass" cavity was added in the middle to suck in various oncoming substances.

Orion's cantilever, outer regions.

The pioneering frontier of human territory.

Not far away from a huge orange main-sequence star, a "planet" with a radius of about 1,800 kilometers flew around the outside of the main-sequence star at an unimaginable speed, and its flight speed was "slapped" The moment it came out, it reached 33% of the speed of light.

This speed is indeed terrifying.

If a star the size of the sun is hit by this planet, there is a high probability that both will perish together.

This planet is the new type of space battleship that human civilization has built over the past one hundred years - the Sirius star space battleship.

The Sirius star space battleship is not just a battleship, it is also a colonial spacecraft itself.

Since the new humans are no longer limited by the earth's gravity, such large space battleships are usually used for both military and civilian purposes.

The ultimate speed of this Sirius star space battleship is 45% of the speed of light, but this can only be achieved with the help of high-speed routes.

If there is no high-speed route, its maximum speed can only reach 24%.

Engineers and researchers of human civilization have already thought of this.

In order to ensure the speed of these new space battleships, solutions have been thought of in advance when designing the space battleships.

That is to use natural black holes and neutron stars for gravitational acceleration. Although natural black holes and neutron stars are unevenly distributed and rarely in a straight line, it is better than nothing.

But speed isn't all the Sirius star has to offer.

The Sirius star's defense and attack power have reached unprecedented heights among various types of space battleships in human civilization.

Since the Sirius star can suck oncoming materials into the loophole thruster through gravitational fields and magnetic fields, it also means that the Sirius star can suck high-energy particles emitted by the enemy into the loophole thruster.

This gives the Sirius star unparalleled defensive power.

The attack power also comes from the hourglass structure in the center. This thing has a spiral vacuum acceleration pipe embedded in the inner wall, which can launch particle cannons with very high energy levels.

In addition, the Sirius star's pseudo-gravitational field generator can also distort stars and planets, destroying the stability of the gravitational field of the planetary system and causing the entire planetary system to enter a state of gravitational chaos.

The Sirius Star, which combines various top technologies of human civilization, has only built a total of 266 ships through more than a hundred years of continuous production.

Through these Sirius star space battleships, human civilization is not only rapidly expanding into the outer layers of the Orion cantilever.

In the Aquarius Arm war with the Silicon Tribe and the Omnics, dozens of Sirius star ships also killed everyone, further compressing the living space of the omnic civilization and the Silicon Tribe civilization in the Aquarius Arm.

With the large-scale popularization of pseudo-gravitational field generator technology and the in-depth exploration of gravity technology, the comprehensive strength of human civilization has become stronger and stronger.

If it were not for the super-light navigation technology, human civilization might have directly entered the Cepheus cantilever base camp of the Silicon civilization.

However, the advantage of human civilization over the Silicon civilization has unknowingly grown larger and larger.

As the gravitational shields of stars are established one by one, the human territory has basically completed the construction of gravitational defense circles in the direction of the Andromeda Cantilever, Centauri Cantilever and the Galactic Center region.

The powerful gravitational defense circle further improves the security within human territory.

At the same time, this also gives human civilization greater confidence in attacking the silicon civilization and the one-eyed civilization.

After all, in this cruel universe, civilizations are never affectionate, but life and death.

Now that human civilization has taken the strategic initiative, of course it cannot miss this opportunity.

If it weren't for the fear of the galactic center area, there might be a powerful first-level civilization, and human civilization would have already marched towards the galactic center area.

After many discussions, the Strategic Analysis Office finally decided to concentrate its efforts on attacking the Silicon civilization in the Cepheus cantilever.

Then attack the one-eyed civilization on the Centauri cantilever, and finally test the galactic center area.

However, attacking the Senying Cantilever of the Silicon Clan civilization also requires a certain strategy. Even if humans have a considerable strategic advantage at this time, they still need to be cautious.

In the early stage, we will attack a small area with all our strength, and then through the neutron cage, we will bring the fire of civilization into the Andromeda cantilever and quickly land on the beach.

After gaining a foothold, it quickly encroached on the territory of the Silicon civilization in all directions through technological advantages, and finally replaced it.
