"No, except for the slight fluctuation of the ray data, no abnormalities were found in electromagnetic waves, visible light, and infrared ultraviolet light."

Zhang Qing shook her head, after the gravitational wave data was abnormal, she immediately contacted the Deep Space Exploration Department of Tomorrow Group, but did not reach valuable data.

Lu Yi was silent for a moment and said: "Nine times out of ten, this abnormal gravitational wave data is caused by the activities of advanced alien civilizations or even wars, and we can't get the information in it, that is, the two sides are not in the same frequency band." ”

I learned from the leader that the existence of extraterrestrial civilizations has been confirmed, but in fact, in addition to discovering some traces and traces, human beings really have not learned about the information of extraterrestrial civilizations.

After seeing the computer technology displayed by the Muba civilization, Lu Yi also understood the reason in his heart.

Quite simply, those alien civilizations are either too weak or too strong.

Civilization is too weak, not to mention whether the other party will emit electromagnetic waves into space like human old rice, even if electromagnetic waves are really emitted, on the scale of tens of light years at every turn, these electromagnetic waves will be completely attenuated and distorted, turning into a mess of data.

In this way, even if the radio telescope array detects it, human beings will not be able to see the pattern, and will only ignore it as cosmic background data.

Civilization is stronger, and the information coding technology will be more advanced, and even if the electromagnetic wave signals emitted by them that spread in the universe are captured by humans, they will not be able to understand them, and they will not be able to see the laws and ignore them as cosmic background data.

This is the same reason that humans do things in front of ants, and ants will definitely ignore them if they don't understand them, and a more academic description is the communication between advanced civilizations, which is like the communication between mathematicians, while human civilization is a child who has not finished kindergarten.

Male mathematicians want to confess to their favorite female mathematician, they write a formula X²+(y+³√X²)²=1, and the female mathematician can understand the other party's mind when she sees it.

You can take this formula and write it to kindergarten children, then you don't know what you are writing, and your heart is equal to the scratch of graffiti.

What's more, Lu Yi guessed that the information transmission between advanced extraterrestrial civilizations is likely to use gravitational waves or faster-than-light communication, which is beyond the scope of human technology, so it has not been discovered.

The signals sent by weak civilizations are too weak, and strong civilizations are too advanced to understand, which leads to the emergence of alien blind spots.

"Lu Lu, has an alien civilization been confirmed to exist?"

Professor Lin asked curiously beside him, they didn't know the secrets of the high-level human civilization, and Lu Yi didn't say much about the Mars exploration plan when he was in a video with them, so he didn't know anything about the Martian Muba civilization.

"Mars has established that civilization existed 4 billion years ago." Lu Yi nodded, and roughly talked about the situation of the Martian Muba civilization and the existence of the Genda civilization.

"Civilization 4 billion years ago?" Zhang Qing and Lin Meng glanced at each other, and they couldn't help but feel a little shocked.

They are not ordinary people, so they know better what this time represents.

The birth of life is inseparable from heavy elements, inseparable from stable material exchange reactions, and almost all elements heavier than hydrogen in the universe are produced from stars.

Observing the starry sky and studying stars, you will find a very interesting data, that is, more than 99% of stars were born in the last 5 billion years.

The universe was created 13.8 billion years ago by the Big Bang, and the first generation of stars did not appear until 3 billion years after the Big Bang.

At that time, almost all stars were massive blue giants, which had a very short lifespan, dying in supernova explosions in about 1 billion years, turning into nebulae and a few heavy elements.

After the death of the first generation of stars, then the second generation of stars is born on the basis of nebulae left over from the explosion of the first generation of stellar supernovas.

Of course, at this time, the number of heavy elements in the universe is still very small, and there may be small meteorites that have been formed by aggregation, but they are still far from forming a planet.

Second-generation stars live longer than first-generation stars, ending their lives in the form of supernova explosions after about 4 billion to 5 billion years, and then third-generation stars are born in the remnants of second-generation stars.

After the selfless dedication of two generations of stars, the proportion of heavy elements in the universe is high enough to form planets.

Before that, there were no planetary beds in the universe for life, and life was impossible.

Even if a very small number of heavy elements gather to give birth to the lucky planet, the first and second generation stars are almost all massive stars, and the massive stars have relatively short lives, and the way of death is supernova explosion.

Against the backdrop of a starry sky full of supernova explosions and baptism of gamma-ray explosions every hundreds of thousands of years, not to mention the emergence of life on these very few planets, even the planet's atmosphere has to be stripped away by gamma-ray bursts.

In other words, at least 8 billion years after the Big Bang, the universe entered the third generation of stars, and life could appear in the universe.

Judging from this data, it is a miracle that Mars had a civilization 4 billion years ago, and what is even more terrifying is that there was already a civilization that could sail at curvature at that time.

"Lu Lu, is this possible?"

"Possibly."

Lu Yi nodded and said: "From the history of the development of the universe, the earth belongs to the first planet to appear life, Mars is also the first planet to appear life, and the Genda civilization is also the first generation of life in the universe.

It's just that compared to the 3.8 billion years it took for our earth to go from life to civilization, the Muba people are more lucky, they evolved wisdom in the first few hundred million years of life, and then developed into civilization within 100 million years.

Compared with the Muba, the Genda people are more lucky, perhaps the Genda people are only a million years ahead or even 100,000 years ahead of the Mubas.

These 100,000 years may be insignificant to the universe, but for an intelligent civilization, it is the time that determines success or failure.

If humanity had appeared 100,000 years earlier, we might have taken a place in the galaxy, or we might have perished.

Now I hope that the inheritance number left by the Pluto Muba civilization can really be preserved for 6 billion years without problems as the last Muba said.

In this way, we can roughly understand what the environment of this starry sky is like through the answer to the demise of the Muba civilization, and know whether the outside civilization is evil or good, so as to determine the next development of civilization.

In addition, the space exploration department on the group's side also discovered a meteorite with a speed of 600 kilometers per second outside the Kuiper Belt a few days ago, and it is still uncertain what the situation is. ”

"There are so many things to worry about on vacation, don't be bald, you are not the only scientist in human beings."

Seeing that Lu Yi looked worried about things and was not ready to give himself a trace of free time on vacation, Zhang Qing rolled her eyes, reached out and took Professor Lin's hand and walked out faster.

"Let's go, Xiaomeng, let's ignore this middle-aged guy who will definitely be bald."

"Hey, Zhang Qing, tell me who is bald? Am I bald? How could I be bald! ”

Lu Yi behind him was shouting a little angrily, isn't it that he was too busy some time ago and his hair was thinning a little, but there is a mentally retarded system, doesn't it grow back in the back......
