"I know that such unfounded speculation does not serve any substantial purpose for scientific research."

As he spoke, Lü Yongchang chuckled softly.

"But that's just your guess!" an academician shouted. "Professor Lü, your guess has never been proven wrong in all this time!"

Lu Yongchang pursed his lips and said half-jokingly, "What if we're wrong this time?"

"Well..." The academician who had spoken scratched his head, and an awkward smile immediately appeared on his face.

A soft, good-natured laugh rang out in the command center.

"Alright, let's get back to the main topic." Lü Yongchang reached out and pulled over a holographic projection, then started writing and drawing on it. "Words are no proof. Next, I will briefly explain to you the reasons for making this judgment."

As soon as he finished speaking, the relaxed atmosphere in the command center suddenly became tense.

Every academician stared wide-eyed, afraid of missing even a single punctuation mark.

After all, everyone knows that Professor Lü's deduction steps are exceptionally unconventional.

In a moment of distraction, you might miss some important information.

"First of all, according to special relativity, objects with mass cannot exceed the speed of light, just like protons and electrons, whose speed can only approach the speed of light infinitely."

"Therefore, we need to introduce a concept for tachyons."

"Virtual quality".

“A long time ago, during the research of quantum physics, we came to a conclusion.”

"Imaginary numbers are not imaginary; imaginary numbers that have meaning in mathematics also have corresponding meaning in reality."

As he spoke, Lü Yongchang quickly scribbled something on the holographic projection.

"Based on the derivation steps here, we can extrapolate the concept of imaginary numbers."

"This leads to the concept of virtual mass."

"And the mass of a tachyon is an imaginary mass."

"That is precisely why it can break free from the constraints of special relativity and become a superluminal particle."

As Lü Yongchang's words echoed in everyone's ears, the complex and intricate formulas in the holographic projection became more and more numerous.

"The speculation about the properties of tachyons is also based on the concept of virtual mass."

"Unlike ordinary particles, tachyons have been moving at speeds far exceeding the speed of light from the moment they are created."

"Its speed will increase indefinitely as energy is dissipated, which is different from what we usually know about particles."

"When its energy is completely dissipated and approaches zero, its speed will approach infinity."

"Therefore, in order to observe tachyons, we must reduce their speed, which means we need to input a large amount of energy into them."

"Even so, its speed will not be less than the speed of light. Only by using warp drive can we have the opportunity to observe it."

Beside him, Tao Yuda murmured thoughtfully, "If the 'fast zo' really exists, we can also draw a simple conclusion."

"What?" Lu Yongchang heard Tao Yuda's muttering and turned to look at him with a questioning gaze.

Tao Yuda was silent for a moment, then said with certainty, "Our universe is composed of two parts: the real universe and the virtual universe. The real universe is the visible universe within the speed of light, while the virtual universe is the invisible universe above the speed of light!"

Upon hearing this, Lü Yongchang also fell into deep thought.

After a long pause, he hesitated for a moment before nodding, confirming Tao Yuda's statement: "That conclusion can indeed be drawn."

Lu Yongchang's words caused quite a stir in the command center.

One by one, academicians from related fields began to discuss the matter.

"No, that's not right!"

Fang Xu's voice drowned out all the subtle discussions: "Professor, Kuai Zi has a big problem!"

"Our cause and effect have been reversed!"

...

Within the cone of light lies destiny.

The emergence of Kuaizi seems to have shattered this proposition.

I understand what you mean.

Lu Yongchang said softly, "For the visible universe, the appearance of faster-than-light particles seems to mean that time reversal is possible, and the cause-and-effect relationship will also be reversed."

"But the universe is fair."

"According to current reasoning, we can only detect tachyons and receive information transmitted via tachyons while traveling faster than light."

"In other words, only when we transcend the light cone can we obtain information beyond the light cone."

"Cause and effect have not been reversed."

“But… what if?” Fang Xu said with a somewhat grim expression, “What if tachyons break through this limit and affect the visible universe?”

"If time could be reversed and cause and effect could be reversed, it would mean that there is a huge problem with our physics system to some extent!"

"This will be an enormous blow to the science of human civilization!"

Fang Xu's words struck everyone's hearts like a heavy hammer.

Reversing time and reversing cause and effect would lead to countless paradoxes.

This will be a disruptive storm for both science and philosophy!

Lu Yongchang took a deep breath, a thoughtful look in his eyes.

He raised his hand and waved it gently: "Quiet down, let me think about it."

The noisy command center fell silent once again.

Lu Yongchang raised his head and looked at the holographic clock interface in the distance.

The hands of the clock ticked clockwise second by second, and the river of time flowed steadily forward.

Suddenly, the hands began to turn backward, and the river of time began to flow upstream!

The entire universe has changed!

The cause-and-effect relationship is no longer maintained. A person walking on the street will suddenly die because a flowerpot will hit him ten minutes later!

Lu Yongchang shook his head vigorously, trying to banish this terrifying image from his mind.

"We have never observed this phenomenon to date."

Lu Yongchang said, word by word, "Perhaps, there exists a self-correcting mechanism in the universe that we are not yet aware of, which could prevent this situation from occurring."

"Or perhaps..."

"Parallel universe theory".

"As long as it affects parallel universes, such an unbelievable scenario will not occur."

When he said those words, Lü Yongchang felt his heart skip a beat.

Could it be that...

Lu Yongchang composed himself and suppressed his unfounded speculations.

He raised his hand and gently rubbed his slightly aching temples.

"Don't think about that too much yet."

"What we can think of, they can think of too."

"Since the universe has been running smoothly without any problems, let's not worry about it."

"Let's think about the specific experimental issues."

“They…” Fang Xu’s expression darkened slightly as he murmured.

Who are they?

These are, of course, those advanced civilizations.

The cleaner, the pastoral type...

Compared to human civilization, these advanced civilizations seem more likely to accomplish such a "feat".

Fang Xu, upon thinking of this, suddenly felt a chill run down his spine.
