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

"[Event Form] theory..."

"Many experiments have been done before, and it is basically confirmed that quantum long-distance communication will not be affected by gravity."

"Professor, previous experiments were conducted around planets or stars." He Bilin reminded softly, "But this is a black hole."

"We are not sure whether the space-time distortion caused by black holes will affect quantum long-distance communication."

Lu Yongchang's face gradually became serious.

He Bilin was right.

Compared with black holes, the space-time distortion caused by stars and planets is really inconspicuous.

He tapped his knuckles on the experimental table in front of him, hesitated for a while, and said, "If this is the case, we may have to return to the original electromagnetic wave communication."

"In this way, the efficiency of information transmission will drop to another level."

Lu Yongchang looked at the holographic projection with some helplessness: "Zero, add an electromagnetic wave communication module to those detectors."

"receive."

"There is another problem." He Bilin continued, "The time flow around the black hole."

"The closer the detector is to the black hole, the slower its time flow is under the influence of gravity."

"Whether it is electromagnetic wave communication or quantum long-distance communication, this problem cannot be avoided."

"The information transmitted by the detector in one second may take decades or even hundreds of years to receive it in its entirety."

The helplessness in Lv Yongchang's eyes grew even stronger.

"I have also considered this issue."

"At present, we can only consume a lot of time to complete this observation experiment."

Chapter 589 The Lost Star

As scientific researchers arrived at Laboratory No. [-] one after another, more and more parts and functions were added to the detector.

Fortunately, all detectors are modular in design, adding or removing functions does not take too much time.

three days later.

When the ring black hole observation network was successfully built, the first batch of black hole detectors left the manufacturing platform built by several engineering ships, drove the antimatter engine, and flew straight towards the extremely bright accretion disk.

……

The moment the observation network around the black hole was activated, a large amount of data rushed into the central computer located on Earth like a flood.

Even though the Optical Quantum Supercomputing Center has been upgraded several times, facing such a huge amount of observation data, there was a short-term freeze.

Fortunately, humans have zero.

It saves civilization countless hours of data processing!

In the laboratory, Lu Yongchang is carefully looking at the processed detection data in the holographic projection, trying to find out what he wants from these complicated data.

"Professor, the 9PL67 detector found an abnormal phenomenon."

Electronic synthesizers interrupted his thoughts.

Lu Yongchang still stared at the holographic image in front of him, and nodded casually.

Along with his movements, a holographic projection appeared beside him.

The next moment, he "reluctantly" withdrew his gaze from the data, and turned to look at the picture beside him.

"what?"

His eyes lighted up slightly, and he let out a small gasp.

"I didn't expect that there is a planet in this place!"

The laboratory was very quiet, and Lu Yongchang's soliloquy was clearly heard by the people around him.

"What? Planet?!"

"Fuck?!"

"..."

For a moment, the quiet laboratory became lively in an instant.

A group of scientists, like children who saw a lollipop, put down their work and walked quickly to Lu Yongchang. With their necks raised, they looked curiously at the holographic image beside him.

A star with several rings slowly orbits the black hole outside the black hole's accretion disk.

The rings appear a faint purple-pink in the light of the black hole's accretion disk.

This fantastic picture did not attract the attention of many scientists.

All eyes were focused on the planet with faint white clouds on its surface.

The yellow-green continent, and the blue waters...

The laboratory fell into a brief silence.

But after that, there was an increasingly heated discussion!

"Fuck!"

"This tm is actually a livable planet!"

"I... it actually has liquid water and vegetation on it!"

"Landing! Landing now! I want to see what the creatures living around the black hole look like!"

"..."

Perhaps because of being too surprised, a series of Chinese quintessence suddenly sounded in the laboratory.

It's no wonder that these scientists are restless.

Even Lu Yongchang opened his mouth slightly, and couldn't believe what he saw with his eyes.

"Zero, send some probes alone and try to land on this planet!"

Lu Yongchang suppressed the excitement in his heart and gave orders to Ling.

"receive."

Looking at the planet in the holographic projection, Lu Yongchang's heart suddenly moved.

"It seems that there is no need to look for other evidence."

"This black hole is indeed devouring a star, and this planet should be a member of the star system."

He murmured to himself, "This planet is really lucky, it didn't fall into the accretion disk of the black hole."

"The Lost Star." Lv Yongchang smiled and reached out and clicked on the holographic projection, "Let's call it the Lost Star."

……

It will take a lot of time for the probe to reach the Lost Star.

Naturally, Lu Yongchang and others would not waste time waiting. After sighing, everyone turned their attention back to the data sent back by the observation network around the black hole.

"Professor, the first black hole detectors are about to enter the accretion disk."

However, the electronic synthesizer sounded again, drawing everyone's attention back again.

In the huge holographic projection, real-time images from the black hole detector quickly appeared.

Unlike the pictures sent back by ordinary detectors, the pictures sent back by these black hole detectors seem a bit stuck.

"Mo Zeyang, report the working status of the ultra-distance communication device."

Lu Yongchang immediately sent an inquiry to Mo Zeyang who was not far away.

This is an additional experiment in the process of detecting black holes.

Verify the so-called [event form] theory again.

Although quantum entanglement effects are not affected in the gravitational fields of stars and planets, the super-strong gravitational fields of black holes are the real test of quantum communication.

After all, the curvature engine also creates an extremely strong gravitational field.

Once it is confirmed that quantum communication will be affected by a strong gravitational field, the research and development of new communication technologies will also need to be put on the agenda.

"Professor, the status of the ultra-distance communication device is normal."

"The entanglement state of all light quanta is normal!" Mo Zeyang's voice came from a distance.

Lu Yongchang nodded thoughtfully: "At present, the [event form] theory has not yet been confirmed."

"It may be that the gravitational field is not strong enough." He Bilin added in a low voice, "According to my calculations, the entangled quantum pairs will be lost within the event horizon of the black hole."

"Event horizon..." Lu Yongchang frowned slightly, "In this case, it is impossible to study the interior of the black hole."

Speaking of this, Lu Yongchang changed the subject: "However, compared with the [event form] theory, I think we should pay more attention to the time deceleration effect."

In order to determine the change of time velocity around the black hole, one of the black hole detectors is equipped with a precise cesium atomic clock, which will send a confirmation message to the fleet every second.

Under normal circumstances, the interval for receiving information by fleets using ultra-distance communication devices should also be 1 second.

But now, the acceptance interval for this confirmation message has come to 2 seconds.

It seems that the increase is not much, but this is the outermost region of the black hole after all.

If the detector continues to approach, the time slowing down phenomenon will become more and more obvious!

"One day on the ground, one year in the sky" may become a reality.

At that time, the data transmitted by the black hole detector in just one second will take 6 minutes for the fleet to receive!

Even, as the detector gradually approaches the event horizon of the black hole, the flow of time will slow down to an even more exaggerated level!

There is no doubt that this will bring great difficulty to the data analysis work!

Lu Yongchang didn't pay too much attention to the fast-moving accretion disk matter in the freeze screen, and his energy was mainly focused on the various boring data sent back by the detector.

After observing for a long time, he frowned and shook his head.

"No."

"The gravitational field is not strong enough."

"Zero, control the detector and continue to approach the black hole."

Chapter 590 Habitable planet?

"drop!"

A faint beep sounded from the side.

Lu Yongchang withdrew his gaze and turned to look at the holographic projection beside him.

It is the information sent back by the probe sent to the lost star.

The probe sent by the fleet has successfully entered the atmosphere of the lost star at this time, and is trying to land on this lucky planet.

As for the basic data of the Lost Star, it has already been presented in the holographic projection, but Lu Yongchang was attracted by the black hole data before, and did not pay attention to the information sent back by the detector.

But now, looking at the data in front of him, his eyes are filled with surprise and excitement.

【Quality: 2.16M⊕】

[Surface Gravity: 1.49g]

[Atmospheric composition: 62.3% nitrogen, 31.9% oxygen...]

[Land area: 67.8%, ocean area: 32.3%. 】

【…】

This is a livable planet!

This was the first thought that came to Lu Yongchang's mind.

If the livability of Dawn Star is 80%, then the livability of this Lost Star may reach 90%, or even higher!

It's lucky!

This was the second thought born in Lu Yongchang's mind!

Currently, its distance from the black hole is perfect!
