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

Fang Xu didn't answer, his mind was highly concentrated, staring at the black unknown substance in the core area.

Last time, [painting] came out of it!

"Don't worry." Lu Yongchang patted Fang Xu's shoulder lightly, "I don't think [Hua] will hide in it."

"These two-dimensional fragments belong to weaponry."

"Isn't it afraid of being fired as a weapon?"

Fang Xu froze for a moment, then burst out laughing, letting go of his high hanging heart.

In the picture, the robot is undergoing final debugging.

When the debugging is completed, various observation instruments will send back various data.

The job of Lu Yongchang and others is to find out the mystery behind gravity from these extremely complicated data.

Chapter 529 Superstring Gravitational Field

Time flies.

With the gradual implementation of the hibernation plan and the migration plan, the originally bustling Dawn Star has once again become deserted.

In the first laboratory of the Academy of Sciences, it was still busy.

"Where's Yongchang?"

Fang Xu frowned slightly, and asked in a low voice, "Are you still in the office?"

Su Yutong nodded lightly, and spread his hands helplessly: "You also know his temper."

"During this time, I couldn't enter the office except when delivering meals."

Hearing this, Fang Xu sighed lightly: "How long has it been..."

Before the words fell, the sound of the door moving came from the side.

Fang Xu was refreshed, and turned his head to look in the direction of Lu Yongchang's office.

The door is open.

Lv Yongchang frowned, staring blankly at the empty corridor in front of him, "shaking" out of the office with a slightly pale face, still muttering something.

Seeing Lu Yongchang's appearance, Fang Xu couldn't help but panic.

At this critical moment, as the backbone of human civilization, Lu Yongchang can't have any accidents!

He hurriedly walked towards Lu Yongchang.

"...No, this is not right."

"One is missing... one is missing..."

As the distance between the two continued to decrease, Lu Yongchang's whispers also reached Fang Xu's ears.

Missing one?

What is missing?

Fang Xu was stunned, and subconsciously called softly: "Yongchang?"

Lu Yongchang trembled slightly, turned his head, and cast his confused eyes on Fang Xu.

After seeing Fang Xu and Su Yutong, the confusion in Lu Yongchang's eyes dissipated a lot.

He reluctantly pulled the corners of his mouth, showing an ugly smile: "It's you..."

"You..." Fang Xu struggled for a moment, but still asked the question in his heart, "What did you mean by what you just said?"

"What's missing?"

Hearing this, Lu Yongchang fell into silence, and the confusion in his eyes became more intense again.

"should……"

"It's a constant."

"A constant that describes gravity."

As he spoke, Lu Yongchang stretched out his hand and waved it casually in the air.

A holographic projection instantly appeared in front of Fang Xu.

In the projection, there are dense and extremely complicated formula symbols and calculation processes.

"This is……"

Fang Xu frowned and glanced at it, only feeling a burst of pain in his brain, but he still managed to keep up with part of Lu Yongchang's train of thought: "The gravitational field equation?"

"No, no, no..." Fang Xu shook his head again and again, rejecting his own judgment, "It seems a little different..."

Lu Yongchang explained softly: "There are some differences."

"Perhaps, you can call it the superstring gravitational field equation."

"As the name suggests, unlike the original gravitational field equation, it is based on superstring theory."

Fang Xu suffocated slightly.

This completely touches the blind spot of his knowledge.

But as the second in command of the Academy of Sciences, he still knows some basic knowledge.

Superstring theory is a type of string theory.

Whether it is superstring theory or string theory, it is believed that the basic unit of the universe is not a particle, but a string.

Strings move through space, creating particles of all kinds.

In other words, all the particles in the universe are nothing more than different vibration modes of strings, and all matter and energy can be explained by the splitting and combining of strings.

It is also true that with the development of human beings, superstring theory has become the most promising theory to unify elementary particles and four kinds of interaction forces.

I don't know if I noticed the thought that flashed in Fang Xu's mind, and looked at the holographic projection Lu Yongchang in a trance and murmured in a low voice: "Perhaps, this equation can realize the grand unified theory that mankind has been pursuing for a long time..."

"Grand Unified Theory?"

This time, Fang Xu couldn't hold back the astonishment in his heart, and exclaimed.

No wonder he reacted violently.

The grand unified theory has been inexplicably attractive to all scientists since the earth age.

As we all know, there are four basic interaction forces in the universe.

Strong, weak, gravitational, and electromagnetic forces.

These four interacting forces build up the entire universe.

So, theoretically, there must be a theory that combines these four forces of interaction.

This is the so-called Grand Unified Theory.

Up to now, human beings who have become a fourth-level civilization have completed the unification of the three interaction forces of strong, weak, and electromagnetic.

But gravity is still the most mysterious existence.

Fang Xu raised his slightly trembling right hand, and gently "touched" the holographic projection of nothingness.

On the one hand, he hopes that Lu Yongchang can bring good news to mankind.

On the other hand, he is well aware of the difficulty of the grand unified theory, and worries that Lu Yongchang will hit a wall on it.

He murmured in a low voice with an extremely complicated expression: "Yongchang, is there any result?"

"There are certain results."

Lu Yongchang frowned, raised his hand and gently rubbed his temple.

Excessive thinking puts a huge burden on his brain.

"Don't get your hopes up too much, though."

"This equation is not complete..."

Speaking of this, Lu Yongchang frowned suddenly: "If this constant is found, maybe humans can use it to realize curvature navigation technology."

During the gap between the two of them talking, familiar faces approached Lu Yongchang,

Obviously, they were attracted by Fang Xu's exclamation just now.

Everyone stood on tiptoe, looking at the azure blue holographic image in front of Lu Yongchang.

"Professor, has the Grand Unified Theory made progress?"

The impatient Tao Yuda asked loudly.

Looking at the extremely longing looks on the faces of the people around him, Lu Yongchang glanced at Fang Xu helplessly, and then stretched out his hand again to swipe in the air.

Under Zero's control, the holographic image magnifies instantly.

The complex formulas and calculation process are displayed in front of everyone in the laboratory at a glance!

"Since everyone is here, let me just say something briefly."

Lu Yongchang cleared his throat and began to explain.

"According to today's research, the Randall-Sundrum model may be the most suitable space-time model for the universe today."

"This theory holds that the space-time we live in is five-dimensional."

"Among them, there are four dimensions of space and one dimension of time."

"Humans, or three-dimensional life, live in a 1+3-dimensional hyperspace in a five-dimensional space-time. In superstring theory, this hyperspace is called a membrane."

"The electromagnetic force, the weak force, and the strong force are all transmitted on this membrane, and will not enter the fifth dimension."

"There is only gravity, which can travel in all dimensions."

"That's why it's so hard for us to parse gravity."

"And this superstring gravitational field describes the gravitational field transmitted in this five-dimensional space-time."

"With it, we can manipulate gravity in disguise and realize so-called curvature navigation."

"Of course, on this basis, I still have a conjecture." Speaking of this, Lu Yongchang was silent for a while, and added again, "It's just a conjecture, and today's human beings can't do this."

"If we can jump out of this membrane for a short time and enter the fifth-dimensional space-time, perhaps, we can realize the so-called wormhole transmission technology."

Chapter 530 The Missing Constant: The Search for the Graviton

As Lu Yongchang's voice slowly fell, the laboratory became extremely quiet.

Only the sound of some instruments working and the slight breathing of everyone remained.

a long time.

Tao Yuda's slightly hesitant voice sounded from the side: "Professor, this equation..."

"There seems to be a problem?"

Hearing this, a smile appeared on Lu Yongchang's face.

He nodded to Tao Yuda with satisfaction: "Not bad."

"At present, it is very likely that there is a lack of a constant to describe gravity."

"Then..." A trace of anxiety flashed in Tao Yuda's eyes, he scratched his head vigorously and said, "How should we find this constant?"

Looking at the holographic projection in front of him now, Tao Yuda felt as if there were ants crawling on his body!

In his opinion, without the equation that must be constant, it is not perfect!

"..."

Under everyone's gaze, Lu Yongchang fell into a long silence.

"Perhaps, we have to search from the direction of the graviton."

"Circumsatellite Particle Accelerator?" Tao Yuda asked in a low voice, his expression slightly moving.

Lu Yongchang hesitated for a moment, then slowly shook his head and said, "The energy level is too small."

"It is impossible for the circumsatellite particle accelerator to knock out gravitons."

In the laboratory, it fell into silence again.

"Go to work."
