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

"Insufficient data to draw conclusions." An electronically synthesized voice sounded from the side.

Lu Yongchang waved his hand impatiently: "Go aside, I didn't ask you!"

zero:"……"

Lu Yongchang quickly got out of the hibernation cabin, and while cleaning up the deep sea fluid left on his body, he thought about the reasons for it.

There must be a demon in the abnormal situation.

Could it be... this area is a territory of advanced civilization?

Human civilization is like a stunned young man, rushing directly into other people's territory!

Thinking of this possibility, he shivered suddenly.

"No, that's not right." Lu Yongchang's face became more serious, he shook his head and vetoed his previous conjecture, "Even if there is an advanced civilization, this universe shouldn't be so quiet!"

If human civilization really rushed into the territory of advanced civilization, then they should also receive something!

Whether it's an expression of friendly information, or an unknown form of attack...

In short, it is impossible to be so peaceful!

"Where are these interstellar civilizations hiding..."

Lu Yongchang's voice suddenly paused.

hide?

Why hide?

Scared?

What are they afraid of?

Advanced civilization?

In just a moment, clues were strung together in Lu Yongchang's mind.

He raised his hand dumbfoundedly, and patted his head lightly: "I understand!"

"Greatly, we have to thank the sweeper civilization and pastoral civilization."

"If it weren't for this great war, our voyage would not be so smooth."

That's right, not long ago, the war between the sweeper civilization and the idyllic faction, which spanned tens of light years, completely scared the courage of the surrounding interstellar civilization.

Every civilization hides itself, for fear of being noticed by those two higher civilizations!

In other words, human civilization came out swaggeringly at this time.

"Perhaps..." Lu Yongchang's face became strange, "These civilizations look at us like fools, right?"

"Professor, Academician Fang Xu is here." The electronic synthesizer sounded softly.

At the same time as the voice fell, Fang Xu's shout came from outside the door.

"Yongchang?!"

"Yongchang, are you awake?!"

For some reason, Fang Xu's voice was filled with excitement.

He frowned, put on his electromagnetic boots, and walked towards the door.

"Noisy, what does it look like?"

"Just woke up from hibernation, you should go to the gravity room for recovery training as soon as possible."

"Next, we have a lot of scientific research tasks, you..."

Fang Xu ignored Lu Yongchang's serious expression.

He reached out and grabbed Lu Yongchang's arm with excitement, and dragged him to the porthole not far away.

"Look!"

"Black hole!"

"This is a black hole!!"

Outside the porthole, there is an incomparably spectacular bright picture!

The mysterious and powerful black hole is clearly presented in front of Lu Yongchang!

Of course, a more accurate statement is what the event horizon of a black hole looks like. The real black hole still hasn't revealed its true face.

The incomparably huge accretion disk exudes an extremely powerful light.

That is the interstellar matter pulled by the gravity of the black hole!

They are like clouds, slowly revolving around the black hole, and gradually approach the black hole under the action of gravity, until they are swallowed by the black hole!

The central area is extremely dark.

This is the event horizon of a black hole - not even light can break free from it!

Around the event horizon is the phenomenon of gravitational lensing that can be observed with the naked eye!

Under the strong gravitational force, the starlight from far away is distorted!

Lu Yongchang stared blankly at the scene outside the porthole, and swallowed hard.

The scolding that reached his lips turned into a classic Chinese quintessence at this moment.

"Fuck..."

Chapter 588 A once-in-a-lifetime opportunity

In the empty universe, a black hole runs quietly.

The huge, bright accretion disk slowly rotates around it, presenting a strange beauty.

Farther away, a tiny fleet was also moving in a circle around it.

Unfortunately, both on earth and in the universe, beautiful things are basically dangerous.

It is no exception.

Compared with the black hole in the central region of the Milky Way, it is only a small black hole.

But under its beautiful appearance, there are still extreme dangers lurking.

Not to mention the various dangerous radiations it releases, but just its incomparably powerful gravitational force.

Once it gets too close, it will be captured by its strong gravity, and even a human fleet with an antimatter engine cannot easily escape.

As for the consequences...

Naturally, it slowly falls into the event horizon of this black hole, the region that even light cannot successfully escape, and finally falls into the center of the black hole-the singularity.

……

【Earth number】.

Lv Yongchang standing by the porthole frowned slightly.

After experiencing the initial astonishment, he soon began to think of his own.

The black hole images observed by the naked eye confirm many previous human conjectures about black holes.

But there is still a little doubt drifting slowly in his heart.

Under normal circumstances, these small black holes do not have such a large accretion disk.

Even, most of the time, it does not have the structure of an accretion disk.

This is why black holes are difficult to observe.

On the one hand, the black hole will absorb the starlight from a distance, and on the other hand, it is due to the gravitational lens effect produced by its huge gravity.

Observing from a distance, even the light behind the black hole can "circumvent" the black hole and pass to the source of observation under the action of gravity.

Simply put, we can observe the side of the black hole, and even the starlight on the back.

Therefore, small black holes without accretion disks are difficult to detect with conventional observation methods.

So why does this tiny black hole produce such a massive accretion disk?

A conjecture appeared in Lu Yongchang's mind.

Could it be... it just captured a star?

And this huge accretion disk is the "corpse" of the star—under the powerful gravitational force of the black hole, the star was completely torn apart.

This is a once-in-a-lifetime opportunity to observe black holes devouring stars!

Maybe, they can rely on observing this process to find that deeply hidden constant!

Thinking of this, Lu Yongchang felt that his heart, which had just been relieved for a while, was beating violently again!

"Go, go to Laboratory No. [-]."

Lu Yongchang said to Fang Xu excitedly: "This is a great opportunity for observation!"

Fang Xu was stunned for a while, but soon, he also wanted to understand the truth.

There was also a flash of excitement in his eyes, without saying any nonsense, he followed Lu Yongchang directly, and hurried towards the laboratory.

……

No. [-] shipboard laboratory.

A miniature holographic model of a black hole hovers quietly in the center of the laboratory.

"Zero, send out all the detectors and build an all-round observation network around the black hole."

After entering the laboratory, the expression on Lu Yongchang's face became more and more serious.

He raised his hand, gently dragged the holographic model, and reached out to click on several areas: "These areas, focus on observation."

Fang Xu glanced at it, and there was a sudden look in his eyes.

According to the current detection data, in addition to the Hawking radiation unique to black holes, the black hole in front of us also emits a large amount of X-rays, gamma rays and visible light radiation.

Except for Hawking radiation, the rest of the radiation mainly exists in the accretion disk region of this black hole.

The reason for this is also easy to explain.

First of all.

Near the black hole, the attracted stars or planets will be completely torn apart by the strong gravitational force until they become atomic or subatomic particles.

And these particles will revolve around the black hole at high speed and form a disk-like structure.

This is the origin of the black hole accretion disk.

Second.

Due to the different running speeds of the matter in the accretion disk, collisions and frictions are bound to occur between them.

This process produces a lot of light and heat.

The extremely high temperature prompts the particles in it to transform into an excited state, which then releases a large amount of rays.

This is what makes black hole accretion disks so bright.

The areas highlighted by Lu Yongchang are basically some places with strong radiation in the accretion disk.

"correct."

Lu Yongchang's voice sounded again: "Modify some detectors, add enough radiation-proof casings to them, and then let them enter the accretion disk area for in-depth investigation."

"and many more."

He Bilin's voice sounded at the gate of Laboratory No. [-].

"Professor, have you figured out what communication method these detectors use?"

He Bilin's question stunned Lu Yongchang.

He responded subconsciously: "Of course it is a quantum long-distance communication device."

"Professor, have you considered the [event form] theory?" He Bilin asked very seriously.

The so-called [event form] theory, simply put, is that the evolution of quantum states in singular space-time and flat space-time is different, and under the influence of gravity, entangled quantum pairs will be lost probabilistically.

Hearing this, Lu Yongchang frowned instantly.
