It's reasonable for me to have a two-way foil for a second-level civilization, right?

It is also for this reason that in the [Kunpeng] mobile laboratory one light-year away, the antimatter engine is continuously outputting majestic energy at full power, and there are loud bangs in the vacuum experiment cabin all the time. ——That was the moment when the experimental subject entered the state of curvature navigation, because the material could not withstand the tidal effect of space-time and thus shattered the sound produced.

Every experiment generates a large amount of data.

These data were continuously sent to Lu Yongchang's office and presented to Lu Yongchang one by one.

As a result, Lu Yongchang's office was covered by layers of holographic projections.

In the ocean of azure blue data, he is like an insignificant dust, quietly huddling in a corner and doing his own calculations.

Time passed little by little.

In front of him, while a more complete space-time model gradually became clear, a set of equations related to the development of human civilization gradually surfaced.

……

Three months passed by.

The closed office door was finally slowly opened again.

At the door, Fang Xu's face was full of excitement and anticipation.

Through the slowly opening gap of the door, he vaguely saw layers of dense blue holographic projections inside the room.

On each holographic projection, there are bright white data and formulas like a book from heaven.

As the gap in the door gradually opened, these azure blue holographic projections gradually turned into light particles and dissipated in the air.

When the door was completely opened, only a huge holographic image was left in the slightly dimmed office.

On the projection, there is an intoxicating picture scroll.

Time and space, under the action of the gravitational field, set off rhythmic waves like the wind blowing across the sea.

Fang Xu stared blankly at the waves in the holographic projection.

In his opinion, at this moment, the space-time waves in the holographic projection seem to be much more alive, and are no longer as rigid as before.

At the same time, in the process of the rhythm of time and space, there is an indescribable beauty!

His gaze slowly turned to the other side, which was densely packed with formulas and equations.

Under the control of zero, these equations also follow the slight rhythm of time and space.

Before he could take a closer look, a figure came out from the depths of the room, which attracted his attention but also blocked part of his vision.

The figure gradually became clear.

Unkempt hair, haggard face...

But none of this could hide the bright, fiery light in his eyes!

Fang Xu swallowed lightly, and asked in a hoarse voice: "Teach, professor..."

"Yes, did you succeed?"

Facing Fang Xu's question, Lu Yongchang slowly stopped his staggering steps, twitching the corners of his mouth, showing a bright smile.

"of course."

he responded softly.

……

one year later.

The first curvature engine prototype was successfully manufactured.

Considering that the power of the prototype is still relatively small, it was installed on a small starship modified from the Xuannv fighter.

【Curvature No. [-]】

This is the code name of this small starship.

For the sake of safety, the test flight location of [Curvature No. [-]] is also not next to the fleet.

Relying on the antimatter engine, it "slowly" came to an open area 0.1 light-year away from the fleet.

Originally, according to Fang Xu's idea, the test site of [Curvature No. [-]] had to be carried out at least one light-year away.

But Lu Yongchang believes that 0.1 light-year is safe enough.

Of course, the main reason is that it took too long to send [Curvature No. [-]] one light-year away.

After the prototype of the curvature engine was successfully born, Lu Yongchang didn't want to wait for a moment!

Finally, after thinking about it for countless days and nights, the real curvature navigation experiment is about to begin!

inside the laboratory.

"Professor, according to the experimental plan, [Curvature No. 10] carrying experimental animals such as mice and gorillas will conduct a [-]-minute curvature voyage."

He Bilin reported to Lv Yongchanghui meticulously: "During the period, the starship's speed will reach 1.1 times the speed of light."

"On the preset route, the Academy of Sciences has deployed a total of [-] detection-type starships to conduct an all-round investigation of the voyage process."

"Do you have anything to add?"

1.1 times the speed of light, which is also the limit level that the first-generation curvature engine can achieve.

Of course, after increasing the power of the curvature engine, the sailing speed will also increase accordingly.

It's just that the higher the sailing speed, the higher the requirements for the curvature of time and space. At the same time, the waves of time and space will become more difficult to control.

After careful calculation, Lu Yongchang came to a conclusion.

According to the current energy level that humans can control, the maximum speed that the curvature spacecraft can reach should be about ten times the speed of light.

In other words, ten times the speed of light should be the ceiling of a fourth-level civilization.

Since the development paths and directions of civilizations in the universe are quite different, the technology tree of each civilization will also be quite different.

There will also be a big gap in the degree of mastery of the curvature engine by different civilizations, and the speed of starships will vary greatly.

Therefore, according to the calculation results, Lu Yongchang divided a simple grade for curvature navigation.

The basis for division is naturally the degree of control over energy.

With a curvature of the first level, the starship travels at a speed between 1c-10c, which is the level of human civilization today.

(c refers to the speed of light, 10c is 10 times the speed of light.)

Secondary curvature, 10c-100c.

Tertiary curvature, 100c-1000c.

Four levels of curvature, 1000c-10000c.

And so on.

According to his guess, the sweeper civilization and the pastoral civilization have a great probability of mastering the fourth-level curvature technology, or even the more advanced fifth-level curvature technology!

"Professor?" He Bilin's voice interrupted his thoughts.

He came back to his senses, and after pondering for a moment, his face showed some satisfaction: "The planning is very good."

"Just follow the plan you said."

"Okay!" He Bilin nodded excitedly.

Chapter 653 Curvature Communication 1.0 Program

The moment the order was issued, the experiment officially began.

Under Zero's control, the antimatter engine inside [Curvature One] began to work at full power.

"The gravitational field generator is ready!"

"The anti-gravitational field generator is ready!"

"Curvature bubbles start to form!"

"..."

Announcements sounded one after another in the laboratory.

At the same time, the peaceful time and space gradually became hideous.

But at the core of the "storm", it is calm.

A small, ever-fluctuating gravitational field smoothes out all the folds of space-time, creating a small, peaceful paradise.

And [War Speed ​​No. [-]] is just in the middle of this paradise!

"Get ready to enter curvature sailing!"

"Countdown: 5,4,3..."

Looking at the rapidly flashing data in the holographic projection, Lu Yongchang clenched his fists slightly and subconsciously held his breath.

With the end of the countdown, [Curvature No. [-]] also disappeared from everyone's sight.

The sound in the laboratory became more and more "noisy", and almost every academician began to get busy.

"Quick!" Lu Yongchang shouted in a hurry, "Zero, confirm the working status of the quantum communication device!"

[Curvature No. [-]] The moment it enters the state of curvature, it means that the ordinary electromagnetic wave communication has failed - it leaves the electromagnetic wave behind!

According to the situation that appeared near the black hole at the beginning, the quantum decoherence phenomenon will also appear in the quantum long-distance communication device under the action of a strong gravitational field.

If the long-distance communication device also fails completely...

That means that every time the human fleet enters the curvature navigation, the quantum long-distance communication module will be damaged in all directions!

Thinking of this situation, Lu Yongchang's face suddenly turned ugly.

"Current entangled state quantum loss rate: 1.72%."

"The communication connection status is normal."

"Information loss rate: 1.72%."

"[Curvature No. 1.1] has successfully entered the state of curvature navigation, and the current navigation speed is [-]c!"

The moment the electronic synthesizer sounded, Lu Yongchang suddenly breathed a sigh of relief!

As stated in the [event form] theory, under the influence of gravity, quantum entanglement pairs will be lost probabilistically.

During the detection of micro black holes, Lu Yongchang discovered that the probability of loss of quantum entanglement pairs is directly related to the strength of gravity.

When the gravitational strength exceeds a threshold, that is, when the curvature of space-time reaches the threshold, the entangled state quantum has a probability of decoherence.

The greater the gravitational strength, the higher the curvature of space-time, and the greater the probability of decoherence!

Therefore, after rigorous calculations, Lu Yongchang had a guess.

When the curvature navigation speed is below 10c, the quantum communication device will not completely lose its function!

This means that at present, human civilization can still use quantum long-distance communication to communicate!

However, the probabilistic loss of entangled state quantum means that the transmitted information will also be probabilistically lost.

But it can be made up for!

By regularly shuffling the order of information and transmitting information at high frequencies, humans may be able to avoid the loss of information during transmission.

To put it simply, it is to arrange and combine a sentence through a specific algorithm, and then send out all these combinations.

In this process, information will be missing probabilistically.

After receiving the information, the receiving end restores the information through an algorithm.

By comparing each piece of missing information, complete information can be obtained.

[Curvature No. [-]] The second purpose of the experiment is to verify the feasibility of this plan!

"Report! No. [-] probe starship has detected curvature fluctuations!" An academician reported excitedly, "The state of space-time curvature is all normal!"

"Good! Good! Good!" Lu Yongchang said repeatedly with a red face.

"Zero, start the curvature communication 1.0 program, and check the integrity of the transmitted information again."

After a short wait.

"Curvature communication 1.0 has been successfully launched."

"The communication connection status is normal."

"Current information loss rate: 0%."
