Time passes by quickly.

With the gradual implementation of the hibernation plan and migration plan, the originally lively Dawn Star once again returned to its deserted state.

And in the first laboratory of the Academy of Sciences, he still looked busy.

"Where is Yongchang?"

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

Su Yutong nodded slightly and spread his hands helplessly: "You know his temper, too."

"During this period, I can't even enter the office except when delivering food."

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

Before the words could be finished, the sound of moving doors coming from the side.

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

The door is open.

Lu Yongchang frowned, stared at the empty corridor directly in front of him with a pale face, and his face "swayed" out of the office, and he kept muttering something.

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

At this critical moment, as the backbone of human civilization, Lu Yongchang cannot have any trouble!

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 murmuring also came into Fang Xu's ears.

One missing?

What is missing?

Fang Xu was stunned for a moment, subconsciously spoke and called softly: "Yongchang?"

Lu Yongchang trembled slightly, turned his head and turned his confused gaze to Fang Xu.

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

He forced himself to pull the corner of his mouth and showed an ugly smile: "It's you..."

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

"What's missing?"

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

"should……"

"It's a constant."

"A constant describing gravity."

As he said that, Lu Yongchang reached out and waved his hand casually in the air.

A holographic projection instantly appeared in front of Fang Xu.

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

"This is……"

Fang Xu frowned and glanced at him, feeling a swelling and pain in his brain, but he still barely followed part of Lu Yongchang's thoughts: "Graining Field Equation?"

"No, no, no..." Fang Xu shook his head repeatedly and rejected his judgment, "It seems a bit 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's breathing was slightly suffocated.

This completely touched his blind spot in knowledge.

But as the second-in-commander 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 particles, but strings one by one.

The strings move in space, resulting in various particles.

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

It is also true that with the development of human beings, superstring theory has become the most promising theory that unifies fundamental particles and the four interactive forces.

I don’t know if I noticed the thoughts flashing in Fang Xu’s heart. Lu Yongchang, who was staring at the holographic projection in a daze, murmured in a low voice: “Maybe, this equation can realize the great unification theory that humans have been pursuing for a long time…”

"Great Unified Theory?"

This time, Fang Xu couldn't help but feel surprised and exclaimed.

It's not his repercussions.

The Great 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 interaction forces, weak interaction forces, gravitational and electromagnetic interaction forces.

These four interaction forces build the entire universe.

Therefore, theoretically speaking, there must be a theory that can combine these four interaction forces.

This is the so-called unified theory.

Up to now, humans who have become level 4 civilizations have achieved the unity of three interaction forces: strong, weak and electromagnetic.

But gravity is still the most mysterious existence.

Fang Xu raised his slightly trembling right hand and gently "stroke" 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 was well aware of the difficulty of the theory of great unification and was worried that Lu Yongchang would encounter a wall on it.

He murmured in a very complicated expression: "Yongchang, is there any result?"

“There are certain results.”

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

Overthinking puts a huge burden on his brain.

"But don't expect too much."

"This equation is not complete..."

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

In the gap between the two of them, familiar faces came to Lu Yongchang.

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

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

"Professor, has the theory of great unification progressed?"

Tao Yuda, who was a little anxious, asked loudly.

Looking at the extremely longing expression on the faces of everyone around him, Lu Yongchang glanced at Fang Xu helplessly, and then reached out to swing through the air again.

Under the control of zero, the holographic image is instantly enlarged.

The complex formulas and calculation processes are presented to everyone in the laboratory at a glance!

"Since everyone is here, I'll just talk about it briefly."

Lu Yongchang cleared his throat and spoke to explain.

"According to today's research, the randall-sundrum model may be the most consistent with the space-time model of today's universe."

"This theory believes that the time and space we live in are five-dimensional."

"It contains four dimensions of space and one dimension of time."

"And humans, or three-dimensional life, live in a 13-dimensional hyperspace in five-dimensional space-time. In superstring theory, this hyperspace is called a membrane."

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

"Only gravity, it can propagate in all dimensions."

"This is also why it's difficult for us to analyze gravity."

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

"With it, we can control gravity in disguise to achieve so-called curvature navigation."

"Of course, on this basis, I still have a guess." Speaking of this, Lu Yongchang was silent for a while, and added again, "Just just guess, humans today cannot do this level."

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