Why have aliens never taken the initiative to contact earthlings, is there really only humans in the

Have there ever been aliens on Earth? Scientists have not been able to come up with an accurate answer to this question, and if they do not exist, how can they explain the discovery of unidentified objects in recent years? But they exist, why haven't any clues been found for so many years?

The universe has a history of 13.8 billion years, and human beings have appeared in this long period of time, and it is very likely that human beings are not the only civilization in the universe, but if aliens exist in the universe, why don't they communicate with humans? Could it be that human civilization is too positive?

Many scientists firmly believe that there must be some kind of connection between civilizations in the universe, such as before the emergence of human beings, biological chains have been formed on the earth, and it is undeniable that human beings have interfered with the changes in biological chains after their appearance. Although human beings are the overlords of the earth, once human beings are placed in the universe and look at them as extremely inconspicuous, we are puzzled by why extraterrestrial civilizations never show any clues.

Einstein once said that there are black holes and white holes in the universe, and in 2019, black holes were discovered, and white holes are still a theory, black holes are like killers, and no one can escape its attraction, Einstein felt that everything in the universe has opposites, for example, we humans will die if we are alive, and new creatures will appear to replace them after the extinction of life on the earth, so at this time, some people speculated that the reason why the white hole was not found was because the white hole was an alien civilization habitat.

It's not for nothing that the speed of light near a black hole can't escape its attraction, and all celestial bodies will disappear from the universe due to the black hole's devouring, so where do these so many stars go? In this regard, there is a huge channel inside the black hole, which is the gateway to the white hole, and humans are on the other side of the white hole, and the aliens are in the depths of the white hole, so this is the reason why they have not come to the earth for so many years.

There is another reason, aliens have discovered human beings, they feel that human civilization has developed too fast in the last few hundred years, and in a few hundred years, human beings are likely to threaten the status of alien civilizations in the universe, in order for their civilization to continue better, they will not take the initiative to contact human beings at all, afraid that human beings will cause harm to them, even if they find human beings, they do not dare to take the initiative to contact human beings.

At present, the location of the white hole has not been determined, in fact, the location of the black hole has been determined, and the ** was successfully photographed, the human aircraft did not dare to approach the black hole, no one knew what was on the other side of the black hole, and no one knew whether an alien civilization existed.

There should be aliens, because the universe is infinite, and everyone doesn't know much about the universe, so there should be aliens in the universe, and maybe aliens don't know much about human beings, so they won't contact us.

From the current various materials, it can be seen that there must be more than human beings in the universe, but also other aliens, and the reason why they do not contact the earthlings is probably because of the language barrier, and they have not understood a lot in the middle, and both sides feel that it is dangerous.

Some scientists believe that it may not be that extraterrestrial civilizations do not have contact with human beings, but that because the current science and technology of human beings are still relatively backward compared with extraterrestrial civilizations, human beings have not discovered extraterrestrial civilizations and cannot get in touch with them.

In the vast universe, I think that on a certain planet, there must be intelligent life like human living there. They don't necessarily look like people, like the dinosaurs of the Cretaceous period. They have the wisdom of humans, or higher than human intelligence.

Maybe they haven't figured out the details of human beings yet, and they don't dare to contact us humans rashly.

First of all, why do aliens contact earthlings? Think about it, for the sake of civilized exchanges? Or is it for the sake of the earth's resources? Or is it for the replenishment of the population? This is known only to real aliens. There must be aliens in the universe, and the universe is big, big.

Yes, the dimension of the universe is so big, there must be other creatures, that is, aliens, this is certain, we can't connect with each other, the reasons may be many, it may be because the distance is too far, they can't find us, or the technology is not advanced enough, so they can't communicate with each other, it is more likely that we are not in the same dimension, not in the same dimension of creatures, there is no way to connect with each other and cognition, according to the current research, we basically belong to three-dimensional creatures. However, other creatures in the universe may not be as inferior as us.

You know, the universe has 12 dimensions, and there may be 4-dimensional beings and 5-dimensional beings. We may not exist in the same dimension, and we may not meet each other. Of course, just because we can't see four-dimensional beings doesn't mean that four-dimensional beings can't see us.

Finding other life in the universe may be a breeze for more advanced beings.

They may have noticed our presence and just didn't bother to contact us and didn't bother to hurt us. Each other's well water does not interfere with the river water, and everyone is safe, and it is fine. There are too many unknowns in the universe, and any bit of star dust is a huge disaster for interstellar travel.

In addition, from time to time there will be terrifying gamma-ray bursts in the universe, which can destroy the entire planet in an instant, not to mention spacecraft.

Therefore, even if aliens have the ability to travel interstellarly, they may not necessarily have the ability to withstand these cosmic threats. Even if they found us, they wouldn't be able to contact us.

I feel like there are aliens in the universe, and the reason why they don't want to contact humans is probably because they are not technologically advanced enough, and they want to live their lives.

At present, human technology is not strong enough, and it is just not found, but there must be.

This is not known at the moment, as no evidence of the existence of aliens has been found.

In the Milky Way, there are at least 100 billion planets like the Sun that can shine on their own. Around each planet, there is a high probability that there will be a large planet. Counting the wandering planets wandering in interstellar space, the scale of operation of large planets in the galaxy can reach the level of 100 billion yuan.

Considering that there are so many extraterrestrial worlds, coupled with the fact that the universe has allowed the Earth to evolve into an intelligent population like human beings and all human beings, there is no reason to believe that the Earth is unique, and it is not easy for these exoplanets to evolve extraterrestrial lives. But the question is, where are all these alien lives? Why haven't you found it yet?

One formulation is that the universe is too big. The universe moves billions of light-years, and such a long distance is beyond the reach of everyone at this stage. Human beings are now unable to fly out of the solar system even half a longitude of 100 million light-years, and these alien worlds hundreds of millions of light-years or even hundreds of thousands of light-years away are also impossible.

Even if sub-light speed travel can be completed in the future, the distance of tens of thousands of light years is still very long. We can't go to an alien world, and aliens probably won't be able to reach Earth. There is no way to fly out of the solar system to carry out on-site testing, and everyone can only search for extraterrestrial life on Earth according to astronomical telescopes.

The distance between exoplanets is very long, and even according to the more powerful astronomical telescopes on Earth, it is completely impossible to recognize the surface of the alien world, let alone immediately look for the aliens that are likely to exist on it. At present, the search for extraterrestrial life can only count on electromagnetic waves. Because of the long distance, after the electromagnetic waves have been dispersed over a long distance, the compressive strength may be greatly attenuated, which will be difficult to detect.

The universe is so large that it isolates the development of reasonable communication between civilized behaviors. Humans have sent data signals to alien worlds thousands of light-years away, and even if there are aliens over there, they will not know about their existence until 50,000 years later.

There may be other reasons why you can't find aliens. It is very likely that there are many civilizations in the galaxy, but if they happen in a different situation, it is very likely that extraterrestrial civilizations appeared earlier than humans, but they are long since they were destroyed. Or alien civilizations know about the existence of earthlings, and they should disdain to find us.

Or maybe there are no aliens at all, and human beings are lonely beings in the universe.

If it's just because of the spacing, there is hope that we can deal with this problem in the future. Immediately running into an alien world in indoor space must cross a long distance and consume a long time. However, if jumping worms are used to connect the Earth with the alien world, interstellar travel will not be easily limited by spacing and time, and everyone may travel freely in the galaxy or even in the middle of the planet.

I think there are reasons for that. But we must be in awe of the unknown. It may be that there are no aliens in the world.

This should not be the case, and I don't think there are any aliens in the world at all, and there is no scientific basis for such a statement.

Possibly, because the universe has always been something we have been exploring, and it has not been explored until now.

It could be yes, or it could be because our current technology is not enough to find aliens.

If there are other intelligent creatures, then human beings are aliens in their eyes, because the earth is suitable for life, and human beings slowly evolve, so there are intelligent creatures such as humans.

There may be more than human beings in the vast universe, human beings are aliens in the eyes of other creatures, and the appearance of human beings is the result of biological evolution.

If humans were aliens, then humans would simply not be able to reach Earth with a spaceship. In addition, the degree of civilization is high and low, even if a planet can give birth to advanced life and evolve civilization, if the degree of civilization is similar to the prehistoric civilization of human beings, then the aliens at this time are not capable of making spaceships at all. If the civilization level of the planet is very high, far exceeding the civilization level of humans, then it is easier for them to directly transform the nearest planet than to immigrate to Earth.

Therefore, the probability that humans are aliens is so low that it is almost impossible.

Humans are not aliens, the first hominins evolved from apes, and when apes walked down trees in order to survive, the first humans gradually began to be revealed.

The intelligence of human beings is far greater than that of all living beings on Earth, and it is precisely because of this that humans seem to be the descendants of aliens, and in some sense, humans may be arranged on Earth by aliens.

How did humans come into being? Is it possible that our ancestors were "aliens" from an alien planet?

Are there really aliens? It's still a mystery! Although there is no definite evidence yet, I believe that there must be other life in the vast universe!

I'm not guessing! The universe is so big that there are no surprises! Although it takes a lot of conditions to give birth to life, it is not impossible, and the earth is an example. There are countless planets like the Earth in the universe, is it only the Earth that has life?

Even if all life needs water, there is more than one planet with water. At present, there are only no planets with liquid water in the solar system, and there are many galaxies the size of the Milky Way in the universe, and there are countless ones that look like the solar system! Are you afraid that you won't be able to find a second Earth?

Although we can't find aliens yet, won't aliens with more advanced technology than us look for us? So far, there have been many things that resemble extraterrestrial spacecraft, collectively known as UFOs, and although 99% of UFOs are masterpieces of nature, aren't there still unproven ones? Aren't they alien spaceships?

To sum up, extraterrestrial life is definitely there! It's just not discovered;

A few days ago, some scientists said that they had calculated that the planets and star systems in the Milky Way galaxy are similar to the Earth-Sun. According to research, there are about 1% of stars of the same type as the Sun in the Milky Way, and at least 10% of them have planets, that is, 100 million stars like the Sun have planets.

So the future will definitely be discovered.
