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

It is nothing more than reporting the location information of the detector and the corresponding time.

He glanced at it lightly.

Sure enough, the same as the initial calculation result, the fleet needs 6 minutes to receive every second of information.

He tapped his fingers lightly on the desk.

"Da da da……"

Characters danced slowly in the holographic projection, gradually converging into strings of meaningful data.

"Gravity is strong enough."

Lu Yongchang's eyes moved slightly, and he murmured in a low voice: "The curvature of space-time is already huge enough. Next, it's time to try to find the so-called gravitons."

ps: The Chinese New Year is busy, and the saved manuscripts are used up... so I still need to update, sorry QAQ

Chapter 620 Continue to Sink!

The United Fleet, on the periphery of the huge accretion disk, slowly rotates around the central black hole.

Round and round.

During this period, the huge fleet passed the Lost Star several times.

Every time, the fleet will send more or less probes to the Lost Star to investigate.

At first, when the probe reached the ground, the vengeful giant tree would cautiously make a tentative attack with its roots.

As for why be careful...

Until now, those two huge craters have just begun to grow saplings!

What's more, from time to time there will be a few strange things whizzing past in the air, who knows if there will be an attack like last time!

It is not stupid, and naturally it will not risk its life to touch the mold of human beings.

After several trials, the giant tree seemed to have figured out the rules, and gradually became familiar with these iron bumps from the sky.

Even, because these iron lumps will release a lot of radiation when they land and take off, the giant trees will "ambush" in advance.

Just like a pilgrimage, whether it is leaves or tree roots, they will cluster around the detector, waiting for the "gift from nature".

As for the giant worms left behind, they gradually discovered this pattern.

However, they are weak and obviously unable to break through the "blockade" of the giant tree, and can only "lick" some radiation materials missed by the giant tree in the farthest outlying area.

Even so, the day when the probes arrived was a rare carnival for them—at least, the giant trees would no longer attack them.

……

Research time flies by so fast.

Especially in the study of black holes, just receiving data takes up more than 80% of the entire research process.

inside the laboratory.

"Is there any sign of the existence of gravitons?"

Lu Yongchang asked with a gloomy face.

"..."

No response.

Lu Yongchang took a deep breath and calmed down the restlessness in his heart.

"Five years!"

"It has been five years since the black hole detector successfully arrived at the target area!"

"After five years of continuous observation, no trace of gravitons was found!"

"Don't talk about the so-called superstring gravitational constant, we haven't even caught the hair of the graviton!"

In the laboratory, Lu Yongchang's restless voice echoed.

While speaking, the bright green background of the technology tree system seemed to appear in his mind again.

[The Missing Constant: Finding the Graviton]

According to the tips of the technology tree, if you want to obtain the superstring gravitational constant, you must find the so-called graviton.

But until now...

"Yongchang..." Fang Xu said hesitantly, "wait a little longer."

"If the time of the black hole detector is used as a benchmark, it has only been a little over five days since it arrived at the target area."

"Don't I know about this?" Lu Yongchang's face became more and more ugly.

"Is it possible, this is why I'm so upset!"

Long before the experiment started, he was prepared to consume a lot of time.

But after waiting for five years, only a series of useless data was harvested. This fact still makes Lu Yongchang a little hard to accept.

Five years, this is five years!

In the past, five years was enough for him to research a lot of technology!

"Although the fleet supplies are sufficient, they are still limited."

"In order to resist the gravity of the black hole, we have to consume a lot of energy every moment."

"What if, what if the black hole detector takes a year to get the data we want?"

"This means the fleet has to stay here for 360 years!"

Fang Xu was silent.

Like Lu Yongchang, this problem has been bothering him.

"According to the calculation of zero, we can stay here for 500 years at most."

"It seems that there is still plenty of time, but judging from the data obtained so far, I don't think the probe can give us a satisfactory answer within this deadline!"

"In 500 years, can we really find gravitons?!"

Lu Yongchang's voice still echoed in the laboratory.

"That……"

He Bilin's voice came from not far away: "Professor, what do you think should be done?"

Lu Yongchang also fell silent.

The laboratory was quiet, and a famous academician subconsciously slowed down his breathing, for fear of disturbing Lu Yongchang's train of thought.

"Let the probe continue to sink!!"

Lu Yongchang's firm voice suddenly pierced the silence in the laboratory.

"But this is already the limit position that the detector can reach!" He Bilin's face changed slightly, and he immediately retorted, "If it continues to sink, the power of the detector's antimatter engine will not be enough to break free from the gravity of the black hole."

"The probe will lose the ability to maintain an orbit."

"Under the gravity of the black hole, it will continue to fall towards the event horizon of the black hole until it is swallowed by the black hole!"

"That's not the most important question."

"Once the distance between the detector and the black hole continues to decrease, the time-slowing effect will continue to increase."

"At that time, if you want to receive a complete piece of data, the time consumed will increase significantly!"

Lu Yongchang did not immediately respond to He Bilin's words, but reached out and dragged a holographic image.

He made a gesture to ask Zero to clear all the data on the projection, and then said again.

"Some time ago, I have been thinking about a problem."

"Perhaps because of the lack of understanding of the specific situation of black holes, there was a problem with our original speculative data."

"The curvature of space-time in the region where the detector is located is still not large enough to allow gravitons to be directly exposed to the visible universe!"

As he spoke, Lu Yongchang raised his hand and began to write on the holographic projection in front of him.

"This is……"

He Bilin on the side frowned, and murmured softly: "The formula for calculating the conditions for the emergence of gravitons?"

"That's right." Lu Yongchang nodded, without any pause in the movement of his hands, and wrote down lines of esoteric numbers and letters like flowing water.

"Among the data sent back by the detector, several pieces of data caught my attention."

"Although they have nothing to do with gravitons, they deviate slightly from our previous models of black holes."

"The observation time is still short, and we are still not sure whether this is an experimental error."

"But if we feed these biases into the extrapolation process..."

The movements of Lu Yongchang's hands became faster and faster, and the handwriting on the projection became more and more scribbled.

Fortunately, the academicians present have long been accustomed to Lu Yongchang's scribbled handwriting, and it is not too difficult to recognize them.

"We can easily come to a conclusion."

The movement of Lu Yongchang's writing and drawing in his hand suddenly stopped, and then, he tapped a string of numbers lightly.

"The curvature of space-time near the black hole detector is far from enough!"

ps: Two updates will resume tomorrow!

Chapter 621 Successful Deciphering

The calculation process in holographic projection is extremely complex.

However, when Lu Yongchang deliberately slowed down the derivation speed, most of the academicians present kept up with his derivation progress.

He Bilin frowned, staring at the last string of numbers on the projection, subconsciously opened a holographic projection, and began to calculate.

"Never mind."

Lv Yongchang glanced at the formulas and figures in the projection, and interrupted He Bilin's initial calculation in a soft voice.

"In 330 years, to be precise, 329 years and 10 months later, we will receive the data from the probes that arrived in the second target area."

The movements in He Bilin's hands paused: "Over 300 years..."

"Then over 300 years..."

"Hibernate." Lu Yongchang said in a deep voice, "All hibernate, and the fleet sails with the lowest consumption."

"Until abnormal data is received."

"Yongchang, what if the abnormal data has not been received?" Fang Xu asked the worst situation.

Lu Yongchang took a deep breath, calmed down his emotions, and said in an extremely helpless tone.

"The fleet will be here for 450 years."

"After 450 years, Zero will lead the fleet to the nearest star system to replenish supplies."

The voice fell, and there was silence in the laboratory.

Every academician showed more or less unwillingness on his face.

"Anyone else have an opinion?"

Lu Yongchang waited for a while, and after confirming that there was no objection, he gave an order to Ling.

"Zero, control half of the black hole detectors to go to the second target area at full speed."

"The remaining black hole detectors maintain their current orbits and continue to perform observation tasks."

Due to the time-deceleration effect, Zero has to deliberately adjust the speed at which information is sent, so it will take a while for the black hole detector to receive the complete command.

After confirming that the order had been executed, Lu Yongchang patted his hands lightly, pretending to be relaxed and said with a smile.

"Everyone, it's time for us to prepare for hibernation!"

"Maybe when we wake up, our detectors will find traces of gravitons!"

Lu Yongchang's words did not dispel the negative atmosphere in the laboratory.

He Bilin and the others had bitter smiles on their faces.

Can such an ideal situation really happen?
