Cataclysmic Era: I can unlock the tech tree

Time flies.

As the hibernation and migration plans were gradually implemented, Dawn Star, which had been somewhat bustling, once again became deserted.

Inside the First Laboratory of the Chinese Academy of Sciences, everything was still bustling with activity.

"What about Yongchang?"

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

Su Yutong nodded slightly, spreading her hands with a hint of helplessness: "You know his temper."

"During this period, I haven't been able to enter the office except when delivering meals."

Upon hearing this, Fang Xu sighed softly, "How much time has passed..."

Before the words were even finished, the sound of the door moving came from the side.

Fang Xu's spirits lifted, and he abruptly turned his head to look in the direction of Lü Yongchang's office.

The door was open.

With a furrowed brow and vacant eyes, Lü Yongchang stared blankly at the empty corridor ahead. He staggered out of his office, his face slightly pale, muttering something to himself.

Upon seeing Lü Yongchang's appearance, Fang Xu felt a pang of panic.

At this critical moment, as the backbone of human civilization, Lü Yongchang cannot afford to be harmed!

He quickly walked towards Lü Yongchang.

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

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

As the distance between the two decreased, Lu Yongchang's murmurs reached Fang Xu's ears.

One is missing?

What's missing?

Fang Xu was stunned for a moment, then subconsciously called out softly, "Yongchang?"

Lu Yongchang trembled slightly, turned his head, and cast a bewildered look at Fang Xu.

After seeing Fang Xu and Su Yutong, the confusion in Lü Yongchang's eyes dissipated considerably.

He forced a smile, forcing an awkward one: "It's you guys..."

"You..." Fang Xu hesitated for a moment before finally asking the question that was on his mind, "What did you mean by what you just said?"

"What's missing?"

Upon hearing this, Lü Yongchang fell silent, his eyes filled with even greater confusion.

"should……"

"It is a constant."

"A constant that describes gravity."

As he spoke, Lü Yongchang casually waved his hand in the air.

A holographic projection instantly appeared in front of Fang Xu.

The projection shows a dense array of extremely complex formula symbols and calculation processes.

"This is……"

Fang Xu frowned and glanced at it, feeling a throbbing pain in his head, but he still managed to follow part of Lü Yongchang's train of thought: "The gravitational field equations?"

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

Lü Yongchang explained softly, "There are some differences."

"Perhaps you can call it the superstring gravitational field equations."

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

Fang Xu's breath hitched slightly.

This completely touched upon his blind spot in knowledge.

But as the second-in-command of the Academy of Sciences, he was still clear about some basic knowledge.

Superstring theory is a type of string theory.

Both superstring theory and string theory posit that the fundamental units of the universe are not particles, but strings.

The strings move through space, thus producing various particles.

In other words, all particles in the universe are simply different vibrational modes of strings, and all matter and energy can be explained by the splitting and binding of strings.

For this reason, with the development of humankind, superstring theory has become the most promising theory to unify elementary particles and the four fundamental forces.

Perhaps sensing the thought that flashed through Fang Xu's mind, Lü Yongchang, who was staring intently at the holographic projection, murmured softly, "Perhaps, this equation can realize the grand unified theory that humanity has been pursuing for so long..."

"Grand Unified Theory?"

This time, Fang Xu couldn't contain his astonishment and exclaimed.

It's no wonder he reacted so strongly.

The Grand Unified Theory has held a mysterious attraction for all scientists since the beginning of Earth's history.

As is well known, there are four fundamental forces in the universe.

The strong interaction force, the weak interaction force, gravity, and electromagnetic interaction force.

These four forces make up the entire universe.

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

This is what is known as the Grand Unified Theory.

To date, humanity, having reached the fourth level of civilization, has achieved the unification of the strong, weak, and electromagnetic forces.

But gravity remains the most mysterious force.

Fang Xu raised his slightly trembling right hand and gently "stroked" the illusory holographic projection.

On the one hand, he hoped that Lü Yongchang could bring good news to humanity.

On the other hand, he was well aware of the difficulty of the Grand Unified Theory and worried that Lü Yongchang would run into trouble on it.

With a complex expression, he murmured softly, "Yongchang, is there any result?"

"There have been some results."

Lu Yongchang frowned and raised his hand to gently rub his temples.

Excessive thinking placed a great burden on his brain.

"This equation is incomplete..."

At this point, Lü Yongchang frowned: "If we find this constant, perhaps humanity can use it to achieve warp drive technology."

In the intervals between their conversation, familiar faces gathered around Lü Yongchang.

Clearly, they were drawn over by Fang Xu's exclamation.

Everyone stood on tiptoe, peering at the deep blue holographic image in front of Lü Yongchang.

"Professor, has there been any progress in the Grand Unified Theory?"

Tao Yuda, who was a bit impatient, asked loudly.

Seeing the eager looks on the faces of the people around him, Lü Yongchang glanced at Fang Xu with a hint of helplessness, then reached out and waved his hand in the air again.

Under Zero's control, the holographic image is magnified instantly.

The complex formulas and calculation processes were laid bare before everyone in the laboratory!

"Since everyone is here, I'll just give a brief overview."

Lü Yongchang cleared his throat and began to explain.

"Based on current research, the Randall-Sundrum model may be the most accurate spacetime model for the universe today."

"This theory posits that the spacetime we live in is five-dimensional."

"It includes four spatial dimensions and one time dimension."

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

"Electromagnetic force, weak force, and strong force all transmit on this membrane and do not enter the fifth dimension."

"Only gravity can propagate in all dimensions."

"This is also why we have difficulty analyzing gravity."

"And this superstring gravitational field describes the gravitational field that propagates in this five-dimensional spacetime."

"With it, we can indirectly manipulate gravity and achieve what is known as warp drive."

"Of course, based on this, I have another conjecture." At this point, Lü Yongchang paused for a moment before adding, "It's just a conjecture; humans today can't do that."

"If we could briefly jump out of this membrane and enter the fifth dimension of spacetime, perhaps we could achieve the so-called wormhole teleportation technology."
