What is the scariest thing that humans may find when looking for extraterrestrial life?

When human beings are looking for alien life, they are most afraid of discovering alien life and being imprisoned by alien life as an intruder. Sealed in a transparent circle shaped like a soap bubble, you can't get out, get in, escape or run away. People experience all kinds of difficulties and hardships, and what they get is disappointment and despair.

When human beings are looking for extraterrestrial life, it may be the most horrible when they are warned to "leave" by aliens, or the looming light of unidentified flying objects emitted by aliens is also the most horrible.

What is the scariest thing that humans may find when looking for extraterrestrial life?

Fermi paradox is a scientific paradox about aliens and interstellar travel, which expounds the contradiction between overestimating the existence of extraterrestrial civilization and lacking relevant evidence. It is reported that a group of scientists from NASA and California Institute of Technology recently conducted a new study. The content of the study is why humans can't find aliens so far. The answer to this question has been made public recently. People can't find alien civilizations, perhaps because they are dead.

If the level of human civilization has reached a star-rated civilization, then the most horrible thing that may happen when looking for extraterrestrial life is that * * * is different from the core values. Alien civilizations may use sub-light speed spacecraft and carry self-replicating intelligent robots to other planets. Because the basic language of alien life is very different from that of human beings, language translation is not enough. A nuclear war destroyed our planet and left mankind with nowhere to go.

When studying the great migration of the origin of human civilization and the civilization it created, we not only see the physiological differences of human beings in skin color, body shape and hair, but also see some core features that run through all cultures, although they lost contact thousands of years ago.

Today, I can find such evidence from movies. People of different races and cultures may have separated from us 75 thousand years ago, but they still laugh, cry and get excited at the same time in the movies. Translators of foreign films have noticed the uniqueness of jokes and humor in movies, although these languages themselves have evolved independently long ago.

Such evidence also applies to our aesthetics. When we visit the exhibition of ancient civilization in the art museum, we will always see some similar themes. No matter what the culture is, we can find works of art depicting landscapes, portraits of the rich and powerful, and images of myths and gods. Although it is difficult to quantify the feeling of beauty scientifically, people's understanding of beauty is often * * *, even in completely different cultures. For example, no matter what culture we study, we can see similar flowers and flower patterns.

Another theme that spans space and time is our common social values. One of its core focuses is to benefit others, which means kindness, generosity, friendship and consideration. Various golden rules exist in many civilizations. Many religions in the world emphasize the same idea at the most basic level, such as charity and sympathy for the poor and the unfortunate.

Another core feature of all cultures is not internal, but external.

This includes curiosity, innovation, creativity and the desire to explore and discover. All cultures in the world have myths and legends about great explorers and pathfinders.

Therefore, the Neanderthal principle admits that our core personality has not changed much in 200,000 years, so even if we are scattered among the stars in the Milky Way, it is likely to retain our values and personality characteristics.

In addition, psychologists also point out that our brain may have a more attractive image. If we take photos of hundreds of different people at random, and then add these photos together with a computer, we will see a composite average image. Surprisingly, this picture is considered attractive by many people. If this is true, it means that there is an average image in our brain, which determines what is more attractive to us. We think that beautiful faces are actually the norm, not the exception.

However, what will happen when we finally reach the state of 1 civilization and can travel faster than light? Will we spread the values and aesthetics of our world to the whole galaxy?

If so, it proves that human beings have changed to type II civilization. In the end, type II civilization may not only exhaust the energy of its parent star, but also exhaust the energy of all nearby stars, and gradually begin to become type III civilization, that is, galaxy civilization. Type ⅲ civilization can not only get energy from billions of stars, but also use the energy of black holes, such as the supermassive black hole in the center of the Milky Way, whose weight is equivalent to 10,000 suns in 200 years.

When the starship moves towards the core of our galaxy, we will find a large number of dense stars and dust clouds, which will become the ideal energy source of type III civilization. In order to communicate in the galaxy, such an advanced civilization may use gravitational waves.

In the future, artificial intelligence may be the terminator of mankind. As we all know, the number of stars in the Milky Way is about 654.38+00 billion to 400 billion. According to the formula, alien civilization appeared about 8 billion years after the formation of the Milky Way. According to the evolution of life on earth, primitive life has appeared about 4 billion years after the formation of the Milky Way.

Einstein first predicted gravitational waves in 19 16, but it was not discovered by physicists until 20 16. Different from laser beams, when gravitational waves propagate, laser beams may be absorbed, scattered and diffused, while gravitational waves can propagate in stars and interstellar space, which makes them more reliable in long-distance communication.

It is not clear whether faster than light travel is feasible, so we need to consider what will happen if it is impossible.

If only a sub-light spacecraft is possible, then Type III civilization may decide to send a self-replicating probe to the stars at sub-light speed, so as to explore billions of worlds in the backyard of the Milky Way. Their idea is to put these robots on a distant satellite.

Satellites are an ideal choice because their environment is more stable and will not be eroded, and because of their weak gravity, spacecraft can easily land and leave on its surface. Using solar collectors to provide energy, satellite detectors can scan planetary systems and send back useful information continuously.

Once the sub-light speed spacecraft lands, the probe will create a factory using lunar materials and make thousands of copies of itself. Each copy will continue to clone and fly to other distant satellites for immigration. So only one robot can get 1000 robots. If each robot can make 1 0,000 robots, then we have 1 10,000 robots, followed by 1 100 million robots and 1 100 million robots. In just a few generations, we can have an inflatable sphere containing trillions of such devices. Scientists call it the von Neumann machine.

In fact, this is the plot in the movie "200 1 A Space Odyssey". Even today, this may be the truest description of the encounter between the earth and alien intelligence. In this movie, aliens put a Von Neumann machine-Blackstone on the moon, which sends signals to a transit station on Jupiter to monitor and even influence the evolution of human beings.

Therefore, the first thing we may encounter is not a monster with small eyes, but a small detector that can replicate itself. It may be a machine miniaturized by nanotechnology, or it may be too small for you to notice. As you can imagine, there is evidence that aliens have been in your yard or on the moon, but it is difficult to find such evidence.

At present, it is believed that the age of the Milky Way is about 65.438+0.3 billion years, which means that if there is an alien civilization in the Milky Way, the initial civilization of the Milky Way will appear about 5 billion years earlier than the civilization of the earth. And 5 billion years is enough for the primitive nucleus to evolve into an advanced civilization, which means that if this alien Wen Mingzhen exists 5 billion years before us,

Then this civilization may already be the top civilization. But why can't we find them? At present, it is generally believed that all alien civilizations did not reach the ability to fly out of the parent galaxy before extinction.

In fact, we earthlings are looking for alien civilization because we are too lonely. When we think about this, we are afraid that we are the only life in the universe. We shouted to the universe, but got no reply. This looks terrible, and we even worry that the universe is virtual.

Some people say that the earth may be really lonely because the conditions for studying life are too harsh, but there is another big filtering theory besides the hypothesis of a perfect earth. According to this theory, it only takes millions of years for animals with average intelligence to evolve into intelligent creatures, so they can evolve into intelligent creatures (civilizations), so the civilization on the planet may be a process of continuous cycle and repetition. Each generation of civilization develops to a certain stage, and after extinction for some reason, it will evolve again and give birth to a new civilization. As early as the 1960s, there was a view that the development of science and technology was a double-edged sword. Scientific progress seems to have advanced human civilization to a higher level, but in fact it has also brought life into a new round of destruction.

It will not be so easy for human beings on earth to get in touch with extraterrestrial life. British physicist Stephen Hawking once said, Never contact with aliens. This is the case with the dark forest theory in Three-body. Maybe many people are curious. Since aliens are so developed, do they still need resources on earth? There should not be any scarce resources they need on the earth. Are they really going to attack the earth? Maybe aliens are not interested in some mineral resources on earth. But there are some resources on the earth that may not be found elsewhere, and that is life on the earth. The environment of other planets is likely to be different from that on earth, so there may be no conditions for life on earth. For these aliens, life on earth is unique, and the genes of biological clock are worth studying. Other alien races may be belligerent. They just want to occupy the territory of other creatures and don't need any reason at all. What they want is the possessiveness of conquest. They don't care what resources there are on the earth, but if we don't contact aliens now, will we not be able to contact aliens in the future? In fact, this matter is not necessarily. The reason why we can't contact aliens now is that extraterrestrial civilization is more developed than human civilization. We humans can only go to the moon now. There is no life on the moon, so I have no ability to actively seek contact with aliens. However, if we can visit other planets hundreds or thousands of years later, our strength may be the same as other planets.

When human beings are looking for alien life, they don't feel any terror, mainly because they haven't found anything yet, not to mention aliens and alien life.

It should be said that the earth, including human beings, feels terror and anxiety, because while studying and exploring the universe, the deeper human beings explore, the more lonely they feel. Just as astronauts look at the earth on the moon, they feel that the earth is lonely and the beauty of the earth is beautiful. What if one day it falls or is sucked away by a black hole, and there are billions of people with families and relatives on it? It's terrible to think about it. Is there only one person on the earth in the vast universe? This is by no means specially arranged by the universe.

The universe that humans can detect is about 93 billion light-years in diameter. What a big world it is, maybe more than that. There is no sign of aliens within 93 billion light years. Only some galaxies, star clusters, nebulae and extremely large balls are found, so the earth and human beings are lonely.

Loneliness is not a good thing. Lonely earth and lonely people are basically the same. Sometimes when you are lonely for a long time, you will have pressure and even fear, because what can a person do? If there is only one person on earth in space, will you feel too lonely in the end, because human beings alone can't realize the civilization of the universe? At present, humans have not even figured out the solar system. Can you really work hard to get out of the solar system, or you will be eliminated if you can't keep up with the trend?

When human beings are looking for alien life, the most terrible thing is to be destroyed when they find it; Or find that many humans on earth are aliens; The most terrible thing is that there are no aliens. No one can tell whether there is an alien civilization, and there is no conclusive evidence so far (of course UFO loyalists may disagree). So what is the scariest truth about human search for alien civilization? Might as well smash a brain hole and imagine.

When aliens are discovered, human beings will be destroyed. This discovery may be mutual. When human beings are looking for alien civilization, alien civilization may also be looking for the destination of interstellar immigrants.

The earth environment is extremely suitable for the survival of carbon-based organic life forms. The elemental composition of cosmic matter is similar, and the body composition of aliens and terrestrial creatures is similar in a high probability. So the earth is very attractive to alien civilizations.

At the current level of science and technology, human civilization may find aliens, but it will also be destroyed by aliens, and the earth will be occupied by aliens. At that time, there may be only a few "unique" in the alien zoo.

No matter from Hawking's "Don't look for aliens" or Liu's "three-body" law of the dark forest of the universe, it is possible to find that aliens are the end of mankind.

Surrounded by aliens, if one day, we find that aliens have already come to the earth, mixed with humans, and even have no reproductive isolation from humans, and there are mixed-race descendants. Is this scene scary? !

Maybe Trump is an alien? Being in a high position, with a series of childish behaviors, first bring down the most powerful country on earth and facilitate alien invasion.

Maybe aliens are around us, and three or four out of ten people are aliens. They use the unique brain waves of aliens, whisper to each other, and then chat casually with the people on earth.

The ultimate horror-we are alone in the universe. In the whole vast universe, perhaps only one planet has produced intelligent life, and even only the earth has produced life. This is not impossible.

The vast universe, with the expansion of space, slowly becomes lifeless. Only human beings are a civilization, struggling to find the meaning of their own existence and the meaning of the universe. And doomed to be lonely and silent in the universe.

I get goose bumps just thinking about it. It's horrible!

These are three horrible scenes that I think of when human beings are looking for alien civilization. Although the unknown is horrible, everyone says that the truth is the most horrible, and no one knows what it looks like.

What is the scariest thing that humans may find when looking for extraterrestrial life? So far, scientists have discovered many "incredible lives" on the earth. For example, there are traces of life in the thin atmosphere outside the Carmen Line, on the shell of the International Space Station, in 100% hydrogen, under the extremely cold ice, in the harsh external environment such as the submarine crater with a temperature of several hundred degrees Celsius.

These findings strongly show that life should be ubiquitous in the universe, so it is not difficult for us to imagine that there must be many intelligent civilizations like us in the universe. So why can't we find these alien civilizations?

In fact, there is a simple explanation that the universe is so big that there is an insurmountable distance between civilizations. Why do you say that? Let's look at the civilization of the earth. With the existing and predictable level of science and technology, it is impossible to fly out of the "small" solar system, let alone to the nearby star system.

Voyager 1 is the farthest man-made object, and it takes tens of thousands of years to fly out of the solar system.

Some people may say that civilizations in the universe can always "speak from a distance" even if there is no physical contact. Then why haven't we received any signal from alien civilization? In fact, this should be because of the following two reasons.

First, because of the lack of time, the time for human beings to light up the "radio communication" skill point is still very short, and the signal of alien civilization has not yet reached the earth; Second, due to the lack of technology, alien civilizations may use more advanced communication methods, such as neutrinos and gravitational waves. Maybe we are surrounded by information from alien civilizations, but we "turn a blind eye".

It can be inferred that at some point in the future, when the scientific and technological level of human beings reaches a certain level, they will receive a lot of information from alien civilizations. What was the scariest thing that humans might find at that time? In my opinion, the most terrible thing is that the signals we receive from alien civilizations are mixed with all kinds of help-seeking information.

Einstein told us that the transmission of any information in the universe can't exceed the speed of light in a vacuum, which means it takes a long time for the signals of alien civilization to reach the earth. For example, an alien civilization is 100 light years away, and the information they send to the earth will take at least 100 years to arrive. So when we receive these distress messages, the alien civilizations that sent the messages may have disappeared from the universe many years ago.

(Red giant devours nearby planets)

This means that these distress messages from alien civilizations confirm the hypothesis mentioned above, that is, all civilizations in the universe can't break through the distance gap set by the universe, and they can only try to communicate with other civilizations by "calling from a distance".

Imagine that the universe is like an endless sea, but many civilizations in the universe can only live on a small island in this sea. Even if they do their best, they will never leave the area near their island, and when the island where they live sinks, this civilization will perish. Obviously, we human beings are facing the same thing, because the earth is also one of many isolated islands. ...

Excuse me, is there anything more horrible than this? Relatively speaking, we would rather believe that the earth is the "zoo" of alien civilization, because at least we still have hope.

We should find extraterrestrial life first. If handled properly, it is not terrible, because at this time, we may have certain opportunities. If conditions permit, you can avoid or make corresponding strategic planning and deployment. The terrible thing is that if alien life finds us first, it will prove that they are more advanced and developed than us earthlings in all aspects. Whether it is good or bad, whether we can make our own choices is unknown.

When humans are looking for extraterrestrial life, terrible things may not happen. Maybe this is a beautiful thing. Maybe alien civilization is much kinder than human beings. The reason why human beings are afraid of extraterrestrial life is that they are often afraid of the unknown. In fact, when human beings are looking for extraterrestrial life, if they can really be discovered or discovered by extraterrestrial civilization, most of them are beautiful. 1. If human beings on earth can discover alien civilizations one day, it means that the scientific and technological level of human beings on earth is high enough to resist the threat of possible alien civilizations. If they are discovered by alien civilizations, it means that the scientific and technological strength of alien civilizations is stronger than that of human beings on earth. Alien civilization may have crossed billions of light-years to meet human beings on earth, so it is unlikely that it came from such a far place to destroy human beings. If we can master the civilization that spans billions of light years, we must have a complete grasp of the energy and resources of the universe, and we will simply disdain this kind of resource on the earth, and we will not rob this tiny resource of human beings on the earth. It is very likely that alien civilization has brought advanced future technology to human beings, and it is a high probability event to let human beings span tens of millions of years at once.

2. As for the latest situation of human search for extraterrestrial life, just the day before yesterday, the U.S. Department of Defense released some UFO investigation reports, pointing out that 144' s report on unidentified aviation phenomenon (UAP) has no clear indication that these UFOs exist in any non-terrestrial creatures. In other words, so far, human beings on earth still know nothing about the existence of alien life.

3, if only by human imagination, there are countless intelligent civilizations in the universe, because the universe is too big. In almost infinite time and space, if only human beings are intelligent civilizations, it is a waste of space. Compared with the universe, the earth is almost negligible. The most terrible thing for human beings is the unknown universe, the lonely existence in the solar system and the concern for life on earth. Only when human beings fly out of the solar system, the Milky Way and the interstellar civilization can they have a chance of eternal life as a whole.

What is the scariest thing that human beings may encounter when looking for extraterrestrial life?

Fermi once pointed out at a small gathering that the universe is so big and so old in time that statistically speaking, extraterrestrial life is inevitable, but where are they? This is the famous Fermi paradox.

According to the normal situation, if there is a planet in a corner of the universe, it may appear as long as it is100000 years earlier than the earth. If there is life and intelligent civilization appears more times than human beings, then why didn't they come to the earth? If we change our way of thinking and give human civilization100000 years of development time, we must have achieved interstellar navigation and gone to more distant exoplanets to find new life and new homes.

Fermi paradox has many explanations. The most extreme one is that there is no other biological civilization in the universe, or that human civilization is the highest civilization in the universe, but this possibility is very slim. The black forest law proposed by Liu in the three-body can well explain Fermi paradox, as follows:

Because we can't judge the good and evil of a civilization, in order to keep our civilization from being attacked, what we can do is to attack at the first time. This is frightening, which is why Hawking has always opposed the active search for extraterrestrial life. This may also be the scariest thing encountered in the search for extraterrestrial life. That is, when we discovered extraterrestrial civilization, we did not establish diplomatic relations, nor did we have harmonious exchanges, but we were greeted with a shotgun.

Hawking's attitude on this point is very clear. Although the search for extraterrestrial life may bring opportunities to our development, opportunities are also accompanied by crises. We should make clear which one to choose, the slow development or the potential threat of extinction. But this is not the case. Plans to find extraterrestrial life have been going on. At present, it is mainly by receiving radio signals from the depths of the universe. At present, China's Eye of Heaven has such a task, looking for extraterrestrial wisdom and civilization.

This is just one of the most terrible things we may encounter in the search for extraterrestrial civilization. We have worked hard for decades, thousands of years or even longer to detect a large number of planets near the solar system, and even many planets in the Milky Way. In the end, we found nothing, and even found no extraterrestrial life. Personally, I think this is quite terrible, which means that life on the earth or Wen Mingzhen is a miracle, perhaps the only one in the galaxy or the universe. In that case, we are too lonely.

But in fact, from a special point of view, extraterrestrial life and even extraterrestrial civilization definitely exist, and the evidence is there. We are the evidence, and more than 8.7 million species on earth are the evidence. In a sense, life on earth is not alien life compared with other celestial bodies. Since we can exist and develop for 3.8 billion years, there is no reason why there is no other life or civilization.

What is the scariest thing that humans may find when looking for extraterrestrial life? When I saw this problem, my immediate thought was that when we found out that "there is no life on the second planet except the earth!" " I think this is the scariest thing.

At present, the earth is our only home in the universe. But is the earth our permanent home? I don't know. At present, the earth's environment is still very suitable for life and human survival. But scientists have found that the brightness of the sun is increasing, and it will increase by 1 0% every1100 million years. At this rate, in about one billion years, the earth will become too hot for human habitation. After 5 billion years, the sun will become a red giant, and the earth is likely to be swallowed up by the sun. Where should humans go at that time?

Some people may say, why should we consider such a long term? It's hard to say whether humans can exist for so long. However, as an advanced intelligent life on the earth, human beings do not want to be trapped on the earth doing nothing. Therefore, we'd better find a new home suitable for human survival before this situation comes.

If human beings find life on other planets in the universe, it means that this planet has the basic conditions to support life. After human transformation, this planet may also be suitable for human habitation. However, after human efforts to search, it is found that there is no life on the second planet except the earth in the universe. This is undoubtedly a very terrible thing.

We can imagine that within 46 billion light-years of Hubble's volume, only the dusty earth has life. What a terrible loneliness it is. This loneliness means that the earth is our only permanent home in the universe, and no other planet in the universe can take us in. We humans will eventually be trapped on the earth and eventually disappear into the universe with the disappearance of the sun. After the disappearance of life on the earth, there is no life in the vast universe.

What is the significance of the existence of a universe without life and human appreciation? If the ultimate result of our exploration of extraterrestrial life is that the earth is the only planet with life in the universe, is this the most horrible thing? I think so. Is that what everyone thinks? Do you think there is a great possibility of extraterrestrial life in the universe?
