65.438+0.5 billion light years away, it sent signals to the earth six times. Are there really aliens?

Whether aliens exist may be what many scientists and astronomy enthusiasts are eager to know, but obviously, human beings have not found any footprints about aliens so far, and all the knowledge about aliens remains in imagination and speculation. On this issue, we should not blindly affirm or deny it, but look at it with dialectical eyes and dialectical thinking.

There are a lot of radio signals in the universe, and the radio signals received by the earth every year are also very diverse. Many scientists believe that radio signals may contain a lot of alien information, but so far, humans have no way to crack it.

Of course, everything is unexpected. If complex and diverse radio signals are just an accident born in the universe, then regular electrical signals may not include them. At a distance of 65.438+0.5 billion light years from the earth, the radio signal came and was sent to the earth six times repeatedly, which made scientists see a glimmer of hope that aliens really existed.

Why are humans eager to know about the existence of aliens? Man seems to be the master of the earth, but this is only on the surface. Only man himself knows that man is a very lonely existence on the earth and in the universe!

Although the diversity of life on the earth makes the earth look gorgeous, there are few creatures, who are as intelligent as human beings and can communicate with human beings on an equal footing. This is why scientists very much hope that there will be aliens outside the earth, at least human beings are not alone.

Scientists found that radio signals were repeatedly sent to the earth six times, which attracted wide attention from the scientific and astronomical circles. Many people think that this may be a signal from aliens. But in fact, there is no way for human beings to decipher these six repeated radio signals, so in a scientific attitude, we can't blindly draw conclusions easily.

Humans are eager to find the existence of aliens. In fact, there are traces to follow. As early as the last century, Voyager 1 space exploration has included human expectations for alien life. Voyager 1 carries a golden record, which contains human language, location and even human DNA, and is interpreted in this golden record.

With the continuous progress of human society, loneliness seems to become more pure, but in fact, in the eyes of many well-known scientists, it is very risky to explore alien life, such as Fermi, the famous proposer of Fermi paradox, and Hawking. They all believe that alien creatures are advanced and aggressive, and if humans find them, they will eventually be invaded.

Higher creatures, powerful creatures destroy lower creatures, weak creatures, there have been examples on earth for a long time, such as Columbus discovering the new continent, but what happened to the new continent in the end? The new world was colonized and expanded, and the local aborigines wanted to cry even more. Taking history as a mirror, maybe that's it.

Liu Zeng, a famous science fiction writer, expounded the Law of the Dark Forest in Three-body. In Liu's view, the universe is like a black forest, full of aggression and cruelty, and there are only hunting rules, so human beings should be cautious, otherwise, at the current level of human civilization, it may just be a certain fish.

However, these are just some guesses of scientists. As for what the discovered electrical signal means, whether it is a natural phenomenon or information sent back by aliens, it can only be explained when human science and technology develop to a certain height in the future. I wonder if you think there are aliens outside the earth?
