The universe is so big, why haven t we ever found extraterrestrial civilizations, where are they hid

The first is that the earth's current technology is still at a low stage, and there is no more comprehensive and in-depth exploration of the universe, and it cannot be ruled out that foreign civilizations are more advanced than us to hide themselves.

Because there are no aliens in this world at all. Humans are known to be intelligent beings. Only other planets have ever had living things.

Because the level of scientific and technological development of human beings still cannot catch up with the development level of extraterrestrial civilizations. There should be, otherwise there are so many things that science can't explain.

There's no way to know for sure, because so far, our science hasn't really encountered such a situation, so there's no way to tell if it's real.

I haven't found it yet, but I think it should be, because no matter how unlikely it is, it will happen.

It exists, and such a civilization is a very large civilization, and it is also very good. It is very interesting for us humans to have a different feeling.

The universe was born 13.8 billion light-years ago, and without that outbreak, the world would be wiped out today, and there would be no one for each other. In fact, everyone has a different opinion about the situation of the aliens. Because of the alien creatures, if we can see them, it means that the innovative technology of the friends is better than them, and if they see everyone, it shows that their innovative technology is better than the others, so it will also produce these different results.

There is a big gap between this and the original ideological concept. People live in space, and there are trillions of organisms on the earth, and if there is no earth, there would be no life, so whether it is the earth or the planets of the solar system, it seems very important in the solar system. It's also very unusual.

However, due to the trend of high-tech development, the professionalism of our space telescopes is becoming more and more prosperous. As people see more and more terrestrial planets, they are also changing.

According to the current presentation information data of the Kepler telescope and the data of the TESS telescope. There must be a terrestrial planet in every four major planets in the solar system. It can be seen that there is absolutely no shortage of extraterrestrial civilizations in the solar system.

After all, interstellar travel must consume a lot of natural resources and energy, and the Internet resources on Earth alone will definitely not attract aliens. Just now, everyone has said that there are so many terrestrial planets, so they can find a few celestial bodies at random Internet resources that have surpassed the earth, so once the alien creatures visit the earth.

Then there will be only two outcomes after all, the first conclusion is to occupy the earth and urge the people to talk to the slaves, the second is for the sake of better friendship negotiation, but the second probability is particularly special and small. In the eyes of extraterrestrial beings, everyone is an "alien creature", so even if an extraterrestrial civilization does exist, it is not necessarily much more upscale than the individual behavior in the history of human development, and it is even very likely to be inferior to the individual behavior in the history of human development. Everyone is an alien high civilization in the universe, and the little beetles on the earth are at the same level of civilization as everyone.

No, every civilization has the value and significance of its existence, and even if there are alien civilizations, our civilization is also very meaningful.

Yes. If the civilization of aliens is higher than ours, then the science of aliens is already quite developed, they have been able to break through the myth that the speed of light cannot be surpassed, they have been able to build huge spaceships beyond the speed of light, and they have mastered the science and technology of instantaneous communication at a distance of hundreds of millions of light years.

They already have the best planet, the sea of diamonds, and the emerald mountains. Automation and intelligence of the production process. There are intelligent robots that replace humans for social production and social management.

This will not be, because aliens are special to us humans, but for aliens, we are also relatively special, but if there is really an alien civilization, then they will think that we are dangerous creatures.

Human beings are not the only ones in the universe, how can we find extraterrestrial civilizations, human enthusiasm for extraterrestrial civilizations has never diminished from ancient times to the present, from the myths and legends of the obscurantist era to search for extraterrestrial wisdom, from the philosophical speculation of ancient philosophers, to modern astronomical observation and reasoning, and then to modern advanced technological means, with the launch of the Kepler space telescope, the detection means have become more advanced. Scientists have not only fixed their eyes on the range of a few light-years or tens of light-years, but have extended further afield, and advanced technology has begun to narrow the scope of searching.

1.Whether it is the original U.S. search for extraterrestrial civilization program "OTZMA", or the more advanced U.S.-Argentina cooperation "Tami" program, and now the most advanced "STEI" program, including China's use of its own large-caliber "FAST" search for extraterrestrial civilization radio signals, although there has been a qualitative leap in the level of detection, but nothing has been found.

2.Accept and analyze any radio wave from space that is captured by the Earth, leaving no possibility unfair. Of course, this work is also the earliest extraterrestrial detection method, which officially began in 1960, and it is also the most convenient method, which is still widely used today.

Humans should actively send radio waves containing information about the Earth into space. This project also began in the 70s of the 20th century. NASA has repeatedly sent radio waves containing information such as human DNA and Earth coordinates into space, and expects to be picked up by extraterrestrial civilizations in the future and respond to us.

3.Various probes will act as messengers for humanity, making contact with extraterrestrial civilizations instead of humans. Starting from the earth, they not only undertake various scientific research tasks, but also carry all kinds of information about the earth.

When they run out of energy, end their scientific missions, and roam interstellar space, if extraterrestrial civilizations intercept them, then we have made substantial progress. Of course, this method also requires a lot of luck. That's the answer to that question.

Personally, I think that people are definitely not the only ones in the universe, because everything has its own laws and laws, so it cannot be only human beings. The only way to find an alien civilization is to constantly research science and upgrade your equipment.

Humans are not necessarily the only life in the universe, and we can find extraterrestrial civilizations through satellites, such as the Mars Explorer satellite.

Human beings are currently the only ones in the universe, and we just want to actively emit signals so that it will be easier to find.
