Age of Cataclysm: I can light up the technology tree

Swish!

The door of the laboratory opened with a bang, attracting the attention of all the academicians in the laboratory.

A slight humming sound came from a distance.

The academicians were not unfamiliar with such a humming sound - it was the sound of the robot's electromagnetic adsorption tracks moving on the deck of the starship.

But this time the tone of the humming sound was undoubtedly much higher than normal.

This means an extremely high driving speed.

Under normal circumstances, for the safety of personnel, the speed of the robot's movement in the starship is greatly limited - at least, it will not emit such a humming sound with such a clear Doppler effect.

It is coming towards the laboratory!

As soon as this thought arose in the minds of the academicians, a mechanical arm robot equipped with electromagnetic adsorption tracks appeared at the door of the laboratory.

Chirp!

The sudden brake brought a slightly sharp friction sound.

The academicians in the laboratory were stunned.

They stared at the scene at the door of the laboratory in a daze, and the expressions on their faces gradually became strange.

"This..."

"Professor Lu?!"

"What the hell?!"

They have seen many mechanical arm robots, not to mention small ones, even large ones that are hundreds of meters long, which can't shock these academicians.

They see Lu Yongchang every day, so naturally they can't be surprised.

But the combination of the two brought an unprecedented shock to this group of academicians - in front of them, Lu Yongchang was standing on the back deck of the mechanical arm robot, and showed them a "gentle" smile.

"Zero, put me down." Lu Yongchang gently patted the mechanical arm in front of him that temporarily served as a safety belt, and said softly.

The next moment, under the eyes of everyone who seemed to have seen a ghost, the mechanical arm slowly loosened and helped Lu Yongchang leave its back deck.

Lu Yongchang walked into the laboratory, clapped his hands with ease and sighed from the bottom of his heart.

"I didn't realize it before. I didn't expect this thing to be so fast. It's much more convenient than walking."

Academicians: "......???"

Lv Yongchang didn't care about the "weird" looks of the academicians, and turned his head to look around.

"Where is He Bi's neighbor?"

He randomly picked a lucky academician and asked him a question.

"He... Academician He hasn't come yet. Today is his day off."

"Tsk..." Lv Yongchang said softly, "He's too slow."

"... Professor, is there something big going on?" The academician asked curiously.

"Big thing?" Lv Yongchang chuckled, "It can be considered a big thing. The second set of data from the black hole detector has been successfully transmitted."

The moment the voice fell, a slight discussion broke out in the laboratory.

"Really?!" In the distance, an academician's face flushed slightly, and he said excitedly, "I have waited for so many years, and finally I have waited for this set of data!"

"Professor, what do you think is the cause of these abnormal data?"

Lv Yongchang smiled and shook his head: "I am not a god. Before I see those data, I can't make an accurate inference."

Just as the academicians were discussing enthusiastically, a burst of hurried footsteps came from outside the laboratory.

A few seconds later, He Bilin, who was panting, appeared in front of the laboratory door.

"Xiao He, you are too slow."

Lv Yongchang said happily: "I recommend something to you, you can..."

"Robotic arm robot, right?" He Bilin didn't care about taking a breath, and interrupted Lv Yongchang's words with a strange look on his face, "Professor, I just called you from behind, you didn't hear it, did you?"

Lv Yongchang: "..."

"Yes, is that true?"

It seems... when I was "racing robots", I really heard a faint shout?

Thinking of this, the smile on his face became stiff.

"Ahem!" Lv Yongchang coughed hard, ignoring everyone's strange looks, and directly changed the subject, "Zero, is the data decompression completed?"

"Release all the abnormal observation data!"

The moment the voice fell, dense and complicated data suddenly appeared in the huge holographic projection in front of the laboratory.

"Zero?"

Seeing this huge amount of data, Lv Yongchang was surprised and asked, "Have you confirmed that it has been screened?"

"The data screening work has been completed." The electronic synthesized voice followed, "The amount of abnormal observation data is relatively large, accounting for about 10%."

Lv Yongchang's expression suddenly became serious.

10% of the proportion, this is already a very large data sample!

He stopped talking and looked directly at the holographic projection in front of him.

...

More than an hour later.

Lv Yongchang breathed a sigh of relief.

The huge data sample basically confirmed the vague guess in his heart.

He turned his head to look at He Bilin, who was standing beside him, and happened to meet He Bilin's gaze.

"Professor, now we can basically determine the reasons behind these abnormal data."

He took a deep breath, was silent for a while, and said solemnly:

"Anti-gravitons!"*2

Under the gaze of all the academicians, Lv Yongchang and He Bilin said in unison.

He Bilin was stunned, and looked at Lv Yongchang in surprise: "Professor, you thought of it too?"

"Of course." Lv Yongchang smiled and nodded gently, "It is very similar to the graviton, with only a few parameters different."

"It is hard not to speculate in the direction of the anti-graviton."

"A magical universe." He Bilin was silent for a moment, and sighed from the bottom of his heart, "When we first discovered the graviton, we all agreed that the antiparticle of the graviton should be itself."

"Just like the photon."

"Now this discovery completely overturns our previous cognition."

"This is also the reason why I didn't dare to make a judgment at the beginning."

Lv Yongchang shook his head slowly and whispered: "Don't say it too early."

"I still think that under normal circumstances, the antiparticle of the graviton is itself."

"Otherwise, many phenomena in the universe will be difficult to explain."

"As for these abnormal data now..."

Speaking of this, Lv Yongchang fell silent again.

After a long time, he uttered a few words with great difficulty: "Perhaps, this is related to the nature of the black hole."

He Bilin's eyes moved, and he quickly understood the meaning behind Lv Yongchang's words.

"Professor, you mean..."

"The existence of the black hole makes the graviton temporarily show the opposite characteristics?"

Lv Yongchang nodded and shook his head.

He looked a little confused.

At this moment, he once again deeply felt his ignorance.

"I... I don't know."

"Maybe it's the influence of the black hole, or maybe it's something else..."

Lv Yongchang's lips moved slightly, and he murmured in a low voice.

On the eve of becoming a fifth-level civilization, a faint dark cloud appeared again in the sky of the human scientific world.
