Why haven t human beings found extraterrestrial civilizations, is it because the universe is too vas

Friends who often watch science fiction movies will find that there are many scenes of cosmic civilizations, the most famous is the picture of aliens landing on Earth in a spaceshipAnd our technology is also constantly developing, many people believe that there is a civilization in the universe, but the question is why human beings have not found extraterrestrial civilizations, is the universe too vast? In fact, it is really very possible, and it is also possible that we will not be allowed to find extraterrestrial civilizations, let's explain.

First of all, this extraterrestrial civilization is a civilization outside the earth, when we step out of the earth and come to the universe, we have really seen the true face of the universe, it is indeed big, and it can't be described by numbers at all, and at the same time, people also begin to think, the earth is a planet in the universe I don't know how many, since the earth can give birth to life and evolve into civilization step by step, then the rest of the universe should also have civilization, that is, the so-called aliens, And their technological civilization is likely to far surpass ours, which is logical.

And we human beings are also constantly exploring the signals of cosmic civilization, for example, a few years ago, China's Tianyan successfully intercepted a signal of a suspected extraterrestrial civilization, when Hawking expressed his opinion "I hope people can not explore the traces of cosmic civilization, it is likely to bring great disasters to mankind", and the reason why we did not find an extraterrestrial civilization The universe is too vast is indeed a reason, such a large distance far exceeds the scope of our science and technology to explore.

And it is very likely that the universe did it deliberately, everything we have may have been arranged by the universe from the beginning, everything is an organic balance system, and no existence that breaks the balance of the system is allowed, if we really find an extraterrestrial civilization, it is likely that the aliens will think that we are an alien invasion race, and once it breaks out, it will be an interstellar war, and this kind of thing is absolutely not allowed to happen in the universe.

I think the reason why human beings have not yet found an extraterrestrial civilization is probably because the universe is too vast. As a result, human technology is now slow to explore more distant places. If the entire universe is only the size of the solar system, and there are extraterrestrial civilizations like Jupiter and Saturn, then human beings have long been connected with them.

Because with the current scientific and technological achievements of the earth, there is no way to go up many planets, and the scope of viewing is too small, so it is normal that no other civilization has been found.

Because there is no extraterrestrial civilization at all, it is not because the universe is too vast.

It is precisely because of the boundlessness of the universe that it is impossible to find extraterrestrial civilizations with the current level of science and technology of mankind.

There are, of course, natural phenomena of other civilizations in the universe, and besides, in every galaxy.

There will be a large planet like the Earth's environment, and there will also be different levels of civilization. Each star system will be controlled by the magnetic field of the main star (the sun), and the development of its civilization can only be based in the space of its own system, and it cannot develop beyond other star systems.

The vast universe is composed of countless stars and their star systems, and countless star systems are all independent entities that circulate in the cycle of matter, and are controlled by the huge magnetic fields of the stars (the sun) in their own system, like countless "cosmic cells", standing in the infinite natural space of the universe.

Each star system is composed of a star and many large planets, all of which have the same development law of the material cycle, will have the natural formation of habitable zone phenomenon, will have a large planet phenomenon like the same environment as the earth, and will have a biosphere.

In the natural formation, there will be intelligent creatures in the survival activities, and there will be the natural occurrence of different levels of civilization phenomena in stages.

Since the different levels of civilization in each star system will be controlled by the huge magnetic field of the main star, on the one hand, the movement of matter at different distances in the space will be locked by the magnetic field of the star; On the other hand, the space vehicles manufactured by intelligent biological civilization are all made of electromagnetic waves.

The signal controls the situation of the command.

Within the range of the stellar magnetic field of the system, the electromagnetic wave signal can be covered, and once the space vehicle exceeds the range of the stellar (sun) magnetic field magnetic, the electromagnetic wave signal will be automatically blocked. In other words, the space vehicles manufactured by the civilizations in the system cannot go beyond the control of the stellar magnetic field, in other words, the space vehicles made by the civilizations of each star system cannot cross the flight activities in other star systems.

In three aspects, the inner space vehicle is a "black hole" object formed between the edge and edge of the star system that cannot pass through the star system, and the "black hole" object has super high-speed vortex and convective motion, and once any object enters, it will disappear without a trace. Therefore, the civilizations of other galaxies in the universe are the inevitable situation that cannot come to the earth, let alone invade our earth.

does not exist. This is because the earth's defense system is relatively strong, and at the same time, the speed of human development is very fast, so it cannot invade the earth at all.

There are other civilizations in the universe; Because the distance between them is relatively far, and the corresponding living environment is different, it is not beneficial for them to invade the earth.

It should exist, it may be too far away, and it may belong to a relatively low-level civilization, so it has not been discovered, and of course there is a possibility that it does not exist.

There really are other civilizations in the universe, and scientists are still investigating this matter, and the reason why they did not invade the earth is because this matter has not been confirmed, so we must look at it rationally.

All assumptions are unfounded. Writer Yang Daxia Yang Ke sent a message.

So far, humans have been searching for extraterrestrial civilizations for hundreds of years. Except for a few UFO incidents with no evidence, not a single extraterrestrial hair, not even a single bacterial spore of extraterrestrial life has been found. But that doesn't mean there are no extraterrestrial life or civilizations in the universe.

If we speak with evidence, we can neither confirm nor deny it now. We'll find out again. So all the talk of extraterrestrials or extraterrestrial civilizations is just speculation.

Whatever you say, you can say that Earth is the first civilization. It can also be said that the earth civilization is still a very low-level civilization, with a level of. The universe is 13.8 billion years old.

If there is a civilization that is 5 billion years old, then this civilization is 8.8 billion years old. How advanced is this? At least it has reached level 3 civilization and can already travel between galaxy clusters.

Even if there had been a civilization a million years ago, it would have been a catastrophe. But where are these civilizations a**? <>

Hubble has now seen galaxies more than 13 billion light-years away and has not found a single hair of civilization. This is the so-called Fermi paradox, and so far, humans have only reached the moon, not even the solar system. And the distance of the universe is measured in light years, and the level of humans is not as good as that of ants on the African plains.

There are also ants, not the pot says the pot is black. Therefore, there is no sense of contact between civilizations of different magnitudes, and there is no need for contact. <>

Because it took us about 150,000 years to go out of Africa and to every corner of the world. It is only a few days before the first human landing on the moon. So I'm not completely denying extraterrestrial life and extraterrestrial civilizations.

This is just human exploration of the universe, this is just a baby stage, just open your eyes and see the universe. As for discovering extraterrestrial life and civilization, human science and technology cannot do it at present. So, we find nothing, in the vast African plains, there is no sign of life except them.

Ants can also create the Fermi paradox. <>

There really is, because science and technology do not meet such high standards, and there are many phenomena that do not have fair and reasonable explanations, so there are big doubts.

There may be, because this civilization is very deeply hidden and lives in a different field from humans, so humans can't find it.

Yes. This is because human beings do not currently have such a level of science to be able to find extraterrestrial civilizations, and have not yet explored this aspect.

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.

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.

How can alien civilizations be so easy to discover, especially for the reason of science and technology, it must be explored step by step, although technology is now very developed, but this is not enough, and when it can really grasp the interstellar civilization and can go out of the solar system to explore the existence of other civilizations, it may be a long time ago.

Everyone may have a lot of curiosity when they see the vast universe, and everyone will guess whether there really is an extraterrestrial civilization, just to find these extraterrestrial civilizations, many scientists have also adopted a variety of methods, although we have not found the emergence of other civilizations, but this does not prove that there is not, it can only be said that the current science and technology has not yet reached the point of development, and can explore without scruples.

Of course, it is also possible that there is a mistake in the way everyone is looking, or that these extraterrestrial civilization signals are simply impossible to search, such hope is still very slim, some goals are simply not possible to observe at close range, only after the real find can we clearly understand some signs of civilization in this galaxy, and the interstellar distance is actually in light years, then this may be hundreds of years or even thousands of light years away.

If you want to truly realize the communication between civilizations, you may have to break the limit of this attack speed, and this requires scientists to pay more effort and time, of course, the transmission of the speed of light signal is already very fast, but this speed may be very slow on other planetary civilizations, maybe in another planet, there is also a civilization that is silently exploring, after all, the universe is so big, and human beings are very small.

The birth of the earth has been 4.6 billion years, life has also appeared for a long time, such a vast universe, if you want to really discover some civilizations, that is, it is thousands of times more difficult than looking for a needle in a haystack, maybe the civilization level of other extraterrestrial life is too high, as ordinary human beings are really imperceptible, of course, all this is just everyone's speculation and curiosity, maybe other extraterrestrial life exists in different forms.
