After listening to the replay of this sound repeatedly.

A bespectacled, brown-haired expert said excitedly, "The sound has obvious regularity and characteristics, unlike anything that was formed naturally or by a small meteorite impact. It sounds like some kind of intelligent life is sending us a signal."

"If true, gentlemen, this would be the first time we have clearly received a signal from extraterrestrial intelligent life, and it would be a great discovery!"

"But how was this sound generated? If extraterrestrial life wanted to send us a signal, why didn't they just use radio waves?" another person questioned.

The brown-haired expert confidently stated, "I suspect it may be transmitted via radio waves or other means, and information loss is inevitable over long distances."

"By striking the outer shell of the space station with some kind of ray or gravitational wave, the integrity of the information can be guaranteed to the greatest extent possible."

"It's somewhat similar to Morse code."

He blurted out his theory in one breath. Although it sounded unbelievable, the other experts couldn't come up with a more reasonable explanation and accepted his theory.

In fact, they also have their own selfish motives. Once it is confirmed that the signal is from extraterrestrial life, these experts who study outer space will immediately become famous and their status will skyrocket.

After reaching a consensus, they shared their hypothesis with the three people on the space station and asked them to simulate "bang bang bang" sounds to send them into outer space and make contact with extraterrestrials.

Meanwhile, in outer space, the engineering robot had climbed back into the Mousse-1 module, and Ye Chen was able to clearly hear the communication between the space station and the ground through the eavesdropping device.

"What? An alien?"

Hearing the experts' judgments, Ye Chen couldn't help but chuckle. "It seems that experts from any country can be unreliable at times."

He shook his head and said, "Forget it, let's ignore these experts. Zhizi, hack into the space station's server and copy all the research data inside."

With the help of the eavesdropping device, Zhizi successfully entered the space station's server without alerting anyone.

The space station has been operating for more than 20 years and has accumulated a large amount of observation data, including hundreds of scientific research results, each of which is invaluable.

In less than three seconds, Zhizi had silently copied them all.

Mousse 1 restarted and quietly left the space station, continuing its journey in outer space. The entire process went smoothly, and no one noticed what was happening.

Ye Chen looked at the data that Zhi Zi had copied and was very satisfied. After instructing the others not to disturb him, he buried himself in the data.

Meanwhile, at the ground control center, language experts have already studied dozens of results from various aspects such as the frequency and intensity of sound intervals.

A day later, a major report appeared in mainstream Western media, titled: "Humanity makes first contact with extraterrestrial intelligent life and communicates with it."

Subsequently, NASA released the full audio on its official website, along with a language glossary!

This news immediately caused a global sensation; humanity had finally made contact with extraterrestrial intelligent life.

At the same time, a large number of self-proclaimed experts in astronomy or linguistics have appeared online to interpret the discovery or translate the alien signals.

Suddenly, the sound of "bang bang bang" became a hot topic, with countless people creating their own interpretations of the language translations published by NASA.

Online, netizens' latest greeting has become "bang, bang—bang—".

If you don't know this, it means you're already out of touch!

One internet celebrity even created a new song called "Welcome to Blue Star" based on this language, using only the "bang" sound.

The new song quickly gained popularity on YouTube, garnering over ten million views in just one day. Even the International Space Station used the song as a symbol of friendship from Earth, spreading it into outer space.

......

Ye Chen was completely unaware of the unintentional hot topic that had arisen, as he was currently in seclusion.

After obtaining more than 20 years of research data from the International Space Station, Ye Chen had a progress bar for unlocking the technology of the Mus civilization appear in his mind.

As he delves deeper into the data, the progress bar is growing rapidly.

In particular, he unlocked scientific and technological knowledge related to space technology one by one, which gave him many practical technologies for building future space bases.

For example, life support systems are needed to provide a suitable environment for human survival in space bases, including life support systems such as air, water, and food.

This research has actually been applied in the International Space Station, although it is relatively rudimentary, it is no different in essence from the life support system of a large base.

Ye Chen has unlocked all the technical data of this technology in his mind. If resources allow, he will be able to build this system soon.

Besides information on life support systems, a lot of other technical data has also been unlocked.

Next, Ye Chen shifted his focus to anti-gravity technology, which was also the main purpose of his space trip.

Decades ago, humans began researching anti-gravity technology on Earth.

With the rapid development of science and technology, especially after the establishment of the International Space Station in Earth orbit, this research has made significant progress.

Antigravity technology is mainly based on the interaction between electromagnetic force and gravity. Simply put, it is to control and influence the gravity acting on an object by precisely manipulating the electromagnetic and gravitational fields around it.

Although it sounds simple in principle, it is extremely difficult to actually implement.

One of the biggest challenges is energy. To levitate an object, a powerful and stable energy source is needed to control the electromagnetic field, which humans did not have before.

However, with the realization of nuclear fusion, this biggest problem no longer exists.

Other issues, such as materials and control, are no longer major problems.

After personally experiencing weightlessness and collecting sufficient research data, Ye Chen no longer found these problems to be problems.

It's only a matter of time before we create anti-gravity equipment.

When the first anti-gravity device is successfully manufactured, humanity will enter a completely new era.

Breaking free from the gravitational pull of planets will provide unprecedented convenience for humanity's exploration of interstellar space.

From then on, humans were able to freely travel and explore space.
