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

"Under the action of a gravitational field, space-time is concave."

"Then, if you let... call it an anti-graviton! If you let the anti-graviton move, will it form an anti-gravitational field?!"

"Under the effect of the anti-gravitational field, the originally flat space-time may bulge!"

"In this way, the threshold for using wave-like space-time to trigger curvature navigation may be greatly reduced!"

Hearing this, He Bilin's face suddenly changed!

After a short thought, his breathing suddenly became rapid, and a flush of excitement appeared on his face.

"Yes, Professor, you are right!"

"With the help of gravitational field and anti-gravitational field, under the same power, we can create larger space-time waves, which will greatly reduce the threshold requirement for gravitational field strength!"

Suddenly, the excitement on He Bilin's face quickly dissipated, replaced by endless confusion and doubts.

"only……"

"How do we obtain antigravitons, and how do we create an antigravitational field?"

"It is impossible for the black hole detector to break away from the gravitational pull of the black hole." He Bilin stood there sluggishly, and said with a confused expression, "At present, it is impossible for us to obtain antigravitons from the vicinity of the black hole."

"It's not difficult!"

Lu Yongchang showed a hint of madness on his face: "Although I don't know why the graviton exhibits the opposite nature, I can be sure that it changes under the influence of the black hole!"

"In this case……"

"Then we'll make a black hole!"

……

After leaving the laboratory, Lu Yongchang hurriedly climbed up to the mechanical arm robot waiting at the door.

"Quick! Take me back to the office!"

Zero, who was ordered, carefully controlled the mechanical arm to fix Lu Yongchang on the back deck of the robot.

Then, accompanied by a sharp rubbing sound, the electromagnetic adsorption track was running at a high speed, leading Lu Yongchang towards the office quickly.

"hiss……"

He Bilin, who had just walked out of the laboratory, happened to see this scene.

He took a light breath of cool air, and his eyes showed a faint emotion: "How do you feel that this thing... works well?"

"Zero, apply for a mechanical arm robot for my office, which must be equipped with electromagnetic adsorption tracks."

"……receive."

Hearing Zero's electronically synthesized voice coming from the side, He Bilin nodded in satisfaction, and walked out of the laboratory.

Before Lu Yongchang left the laboratory, he gave him a task.

He has no relevant experience and needs to seek help from Fang Xu, Cao Liangcai and others.

……

After returning to the office, Lu Yongchang sat in his seat and hastily closed his eyes.

He had a hunch.

After breaking through this most critical node, the technology tree system can already provide him with corresponding help!

Compared with the past, after the brain is quantized, the speed of entering the technology tree system is much faster.

The background of the mottled technology tree appeared before his eyes again.

Although he had seen it many times, every time he saw this mottled and seemingly disorganized background, he would frown.

He thought for a long time, but he still couldn't figure out the meaning of this mottled background.

He "shaked his head" and focused his attention on the bright white technology tree suspended in the mottled background space.

【Curvature Navigation Technology】

A half-dimmed, half-bright cursor hangs silently on the top of the branches of the technology tree.

Lu Yongchang skillfully focused his attention on the cursor, and then unlocked the restrictions on the quantum state of the brain.

The originally calm thoughts became turbulent again.

With the gradual concentration of attention, the technology tree system began to play its role.

The chaotic inspirations in my mind gradually dissipated, replaced by inspirations similar to "precise push".

Time passed little by little.

A model of curvature navigation gradually took shape in his mind.

……

after one day.

[Earth] In Laboratory No. [-].

Lu Yongchang stood in front of the academicians, and beside him was a blue holographic image.

In the holographic image, there is a model constructed of translucent white lines.

Looking at everyone's suspicious eyes, Lu Yongchang said slowly:

"Everyone, this is a schematic diagram of the working principle of a curvature engine."

These words directly ignited the originally quiet atmosphere in the laboratory!

"Based on the observation of abnormal gravitons, we can basically draw a conclusion."

"Under the influence of some unknown mechanism in the black hole, gravitons exhibit the opposite properties."

"Although there is no definite experimental evidence to support it, I believe that the anti-gravitational field exists, and the space-time bulge is also achievable."

"And this is also the core working principle of this curvature engine."

Lu Yongchang cleared his throat and began to explain again.

"With the help of the anti-gravitational field, we can make the space-time behind the aircraft expand and bulge, while the space-time in front of the aircraft shrink and sag."

"In this way, time and space will become waves that keep rolling forward."

"And the aircraft is constantly moving forward under the impetus of this wave."

"Of course, in order to prevent the aircraft from being torn apart by the space-time tides, we need to smooth the space-time waves around the aircraft as much as possible."

"In other words, under the action of the curvature engine, it is not the aircraft that moves, but the space-time where the aircraft is located!"

"Since the spaceship itself is almost stationary relative to time and space, it can also allow us to break through the speed limit of relativity while avoiding the time deceleration effect of relativity!"

"Realize the super-light speed voyage in the true sense!"

The moment the voice fell, there was a burst of warm applause in the laboratory!

Lu Yongchang raised his hands slightly, and pressed them against the air.

The applause gradually stopped, and the laboratory became quiet again.

"As for the creation of the anti-gravitational field..."

"We first need to create a miniature black hole."

"As for how to make it..."

"That's the main point of what I'm going to say."

As he spoke, his right hand flicked across the holographic projection beside him.

The curvature engine model quickly dissipated, replaced by a few bright white Chinese characters.

【Ring black hole super large particle accelerator】

Chapter 646 New Accelerator Construction Plan

"hiss!"

These big characters in the holographic projection drew a gasp.

Almost every academician showed shock on his face.

Lu Yongchang's voice sounded again: "Theoretically, we can accelerate particles to a sufficient energy level through the ring black hole particle accelerator."

"At the moment of the collision, we can get a miniature black hole in the true sense."

"Miniature black holes are extremely unstable, and will evaporate themselves due to Hawking radiation almost at the moment of birth."

"Therefore, we need some solutions to stabilize this miniature black hole..."

"professor!"

After hesitating for a moment, an academician took a step forward and interrupted Lv Yongchang: "I think the most important issue at present is not how to stabilize the miniature black holes."

"Huh?" Lu Yongchang raised his eyebrows, "Say it."

"Ring black hole particle collider... how do we make it?" The academician hesitated and said, "Professor, this is different from the ring planet particle collider, it needs a lot of matter."

"At present, the fleet does not have so many material reserves."

"Even, our antimatter reserves don't allow us to stay near the black hole for too long."

"No matter from which point of view, building a ring black hole particle collider is a huge project that is impossible for the current human civilization."

His words resonated with many people.

It's normal and easy to understand.

So far, the fleet has spent nearly 350 years receiving the data.

The fleet's antimatter reserves only allow them to stay near the black hole for 500 years.

In other words, the human fleet has at most 150 years left.

According to the conventional thinking, even if the materials are abundant, I want to build a ring black hole particle accelerator, and then conduct corresponding experiments, and develop a curvature engine on this basis...

150 years is not enough!

Looking at the doubts on the faces of the academicians, Lu Yongchang showed a gentle smile again: "No, in a sense, we can even complete the construction of the ring black hole particle accelerator within a year."

"what?!"

"This is impossible!"

"Professor, are you kidding me?!"

The moment the voice fell, the originally peaceful laboratory exploded in an instant.

Almost everyone is loudly expressing their opposition and doubts.

One year to build a ring black hole particle accelerator?

Even if it is zero, under the current computing power conditions, such a feat cannot be accomplished!

Lu Yongchang chuckled, turned his head, and glanced at He Bilin not far away.

"Let Academician He answer your questions in this regard."

"He is fully responsible for the construction of the ring black hole particle accelerator."

Lu Yongchang's steady and powerful voice suppressed the noisy doubts in the laboratory.

……

Facing everyone's eyes, He Bilin turned on a holographic projection with a calm expression.

The real-time model of the black hole appeared in front of everyone.

Looking at the black hole accretion disk that has almost dissipated and only emits a very faint light, the laboratory fell silent instantly.

"Everyone, we don't need to maintain traditional concepts in the manufacture of ultra-large particle accelerators."

"We all know that the sweeper civilization is using the power of civilization to create a particle accelerator around the universe."

"According to the traditional concept, a particle accelerator around the universe needs to consume an extremely large amount of matter, and even emptying out the entire universe is not enough."

"Then how did the sweeper civilization do it?"

He Bilin's voice echoed in the laboratory, and the expressions on the faces of the academicians also changed slightly.

"So we need to think differently."
