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

The robot that was close to the stabilizer tilted and was thrown directly against the wall beside it.

"Zero?! What's going on?!"

Lu Yongchang's expression changed slightly, and he shouted loudly.

Could it be a magnetic field problem?

impossible!

Before the start of the research project, Lu Yongchang considered this point. Logically speaking, these robots should not be affected by the magnetic field!

Zero didn't reply, but the camera quickly changed direction and focused on the hapless robot.

Under the shooting of the high-definition camera, the robot's legs and hands have become a twist!

"This……"

Lu Yongchang's face changed, and an unbelievable idea slowly emerged in his mind.

"Gravity shield?"

Fang Xu on the side expressed the conjecture in Lu Yongchang's mind in a hoarse voice.

"I'm afraid it is." Lu Yongchang's eyes burst into light, and he said excitedly, "If you want to ensure that it is not polluted by any particles, a gravitational shield is an excellent option!"

Sure enough, [Painting] had tampered with the drawing of the stabilizer!

The so-called strong magnetic field is probably just a deception!

For the two-dimensional core, it should be the gravitational shield that really works!

"Can we break it?" Fang Xu swallowed, and asked curiously but timidly.

"I'm afraid not."

Lu Yongchang stretched out his hand to operate the small holographic projection on the side, and said with some regret: "This layer of gravitational shield is very strong."

"Judging from the phenomenon of gravitational lensing, its strength is far above the gravitational shield of the flagship of the Lator civilization."

Fang Xu was at a loss for words when he heard the words.

This is fucking shit.

They can't even solve the gravitational shield of the Lator civilization, let alone this thing in front of them.

"It can be regarded as a little harvest." Lu Yongchang's eyes flickered, "At least, we can analyze gravity by observing this gravitational shield."

"certainly……"

Speaking of this, Lu Yongchang raised his head again and glanced at the extremely deep darkness inside the gravitational shield: "I'm even more curious about what's inside."

"What kind of substance can restrain such poorly stable two-dimensional fragments?!"

Suddenly, as if thinking of something, Lu Yongchang suddenly raised his hand and patted his forehead.

Under the gaze of everyone, he murmured to himself excitedly: "Could it be..."

"Is it dark matter?"

Chapter 520 Dark Matter

Lu Yongchang's mumbling voice was extremely clear in the quiet laboratory.

"Dark matter?!"

The expressions of the researchers standing beside him changed slightly, either excited or worried...

"Professor, why do you think this is dark matter?"

From the side, He Bilin's inquiry sounded.

……

Unlike antimatter.

Antimatter is the matter that is actually observed by human beings.

And dark matter...

As of today, human civilization has become a fourth-level civilization, but it still exists in theory.

As one of the top astronomers in the Academy of Sciences, He Bilin naturally understands the mystery of dark matter.

First, is the definition of dark matter.

It is an invisible substance that may exist in the universe.

At the same time, it is the main component of the matter in the universe, but it is not a component of various celestial bodies in the universe.

According to various observation results, the proportion of dark matter in the total matter of the universe has reached an astonishing 85%, and at the same time, it accounts for 27% of the total mass-energy of the universe!

As for all kinds of celestial bodies visible to the naked eye, they only account for about 5% of the total mass energy of the universe.

Calculated in this way, the addition of various celestial bodies and dark matter only accounts for 32% of the total mass energy of the universe.

So, what about the remaining 68%?

They are the so-called dark energy.

Compared with dark matter, dark energy is more mysterious, and it may even be the driving force behind the accelerating expansion of the universe!

Although humans have not directly found the so-called dark matter, there is a lot of evidence for its existence.

For example, the operation of the Milky Way.

In an ordinary star system, due to the gravitational effect of the main star, the closer the star is to the star, the faster the revolution speed, and the farther the star is, the slower the revolution speed is.

But in the Milky Way or other spiral galaxies, this rule is invalid.

In the Milky Way, all stars rotate at almost the same angular velocity.

To put it simply, it is contrary to ordinary star systems, the closer the stars are to the center of the Milky Way, the slower the revolution speed; the outer stars are the faster the revolution speed!

This may lead to a result-because the outer stars are running too fast, they escape the gravitational control of the central black hole of the Milky Way, and then cause the Milky Way to disintegrate!

But that didn't happen.

The distribution of matter in galaxies can be calculated through the distribution of the diffusion velocity of visible celestial bodies in galaxies. After various observations and calculations, the distribution of matter in most galaxies and star clusters is different from the distribution of observed matter—visible matter only occupies A very small fraction of the total mass.

In other words, there is an invisible substance scattered throughout the universe.

This is dark matter.

In a galaxy, dark matter acts as the "glue" between the stars, allowing all the stars to rotate around the center of the galaxy at almost the same angular velocity, and preventing the disintegration of the galaxy.

……

Lu Yongchang silently watched the picture in the holographic projection.

In the picture, the mass of black matter located in the core area of ​​the two-dimensional debris restraint device quietly "stays" in its position.

He Bilin turned his head and looked at Lu Yongchang suspiciously.

Although he didn't know what Professor Lu was thinking at this time, he still suppressed the confusion that kept emerging deep in his heart.

There is no other reason.

When he was thinking about a problem, he didn't like others to interrupt his train of thought.

As for others, He Bilin would naturally not interrupt Professor Lu's thoughts at such a time.

"I……"

Suddenly, Lu Yongchang's lips moved slightly, and he murmured in a slightly confused tone: "I don't know either..."

"However, according to our theory, it does fit the definition of dark matter very well."

"First, dark matter is highly stable."

"The ability to confine two-dimensional fragments with such an active nature is undeniable in its degree of stability."

"Secondly, dark matter basically does not participate in electromagnetic interactions."

"That is, it interacts very weakly with photons, and it's basically not emitting light."

"That fits perfectly, too."

"The third..."

"Dark matter participates in gravitational interactions."

"This may explain the strength of the surrounding gravitational shield."

Lu Yongchang's eyes were full of confusion: "If [Painting] simply wants to isolate the interference of particles, this gravitational shield does not need such a high strength at all."

"According to the latest calculation results, its strength is even more than [-] times stronger than the gravitational shield made by Latour's flagship."

"so……"

"Its main role is likely to be to confine the dark matter in it."

He Bilin frowned, and nodded thoughtfully: "You say that...there is indeed a bit of similarity."

"But, Professor, I have a question."

"Tell me." Lu Yongchang nodded, turned his gaze away from the holographic screen, and turned to look at He Bilin who was walking beside him.

Facing the gazes of Lv Yongchang and a group of scientific researchers, He Bilin pondered for a moment and asked.

"What is its energy source?"

"I don't think the energy produced by the fusion reactor in this small starship can support such a high-strength gravitational shield."

Hearing this question, Lu Yongchang also fell silent.

Yes.

What is its energy source?

With the deepening of the research, one mystery after another appeared in front of the Academy of Sciences.

Although the number of reactors in this starship far exceeds that of normal starships, it is only a fusion reactor of a second-level civilization after all.

Not to mention the seventh-level civilization, just for today's human beings, the energy produced by any starship equipped with an antimatter engine is not of the same order of magnitude as it!

"perhaps……"

Lu Yongchang stared at the simple but extremely aesthetic restraint device in the holographic projection, and slowly said: "The so-called fusion reactor power supply is just a scam by [painting]."

"It must have its own unique energy system, we just don't know it."

"Professor, what should we do now?" He Bilin looked at the huge restraint device in the holographic projection with some reluctance.

Everyone knew the meaning of He Bilin's words.

The restraint device in front of him contains too many technologies far beyond human civilization.

To scientists, it's like a piece of poison laced with honey.

Like other scientists, Lu Yongchang's face is full of tangled words.

"call……"

He let out a long breath of turbid air, as if letting go of the obsession in his heart, his whole body was relaxed.

"Observe and test the gravitational shield."

He glanced at the dark matter in the core area with nostalgia, and said softly: "Whether it's dark matter or a brand-new energy system, it's not something we can touch today."

"Zero, monitor it in real time, and report immediately if any abnormality occurs!"

The order had been issued, and everyone present could only forcibly suppress the desire for truth in their hearts.

Chapter 521 Mutation

a few hours later.

The hour hand of the holographic clock on the wall points to the number 3.

The night is getting darker and darker, and there are fewer and fewer researchers in the laboratory.

Lu Yongchang stood motionless in front of the huge holographic projection, staring fixedly at the mass of black matter in the center of the screen.

In the face of various and endless observation and detection methods of human beings, it stands still.

During the detection process in the past few hours, it just quietly suspended in the core area of ​​the restraint device, silently "watching" the meaningless movements of the group of "ants" around it.

"How arrogant..."
