If we have contacted outward life, will this cause human overwhelming?

If aliens really exist, then hiding our wisdom and curiosity will not stop them from discovering our world

And it will only hurt us. When we explore the wisdom of the outside world, we have a lot of hope and fear, but are these hopes or fear basically?

One of the most wonderful issues is related to our position in the universe. In the 13.8 billion years of the universe evolution, after the Earth formed 4.5 billion years, or at least after 4 billion years of life appeared in our earth, human beings have done it. This is the first time -at least, we have a lot of evidence -a civilization with wisdom, perception, and technology on the earth. We can receive signals from the distant universe, identify their sources and attributes, and even surpass the restraint of our planet home, and start exploring the vast space outside the home.

Although we have been looking for signs of other wisdom life in the universe for more than half a century -looking for extraterrestrial wisdom -at present we still have no strong evidence to prove their existence. At the same time, many people advocate strengthening our positions and existences, hoping to attract the attention of aliens to get in touch with other high civilizations of the Galaxy. Others believe that this is a terrible, which may lead to self -destruction strategies. What should we think? More importantly, what should we do? The following is what Garry Davis wants to know. He asked: "I have thought about the civilization of off -site civilization for a long time. Everyone here is a layman. But I am still right to Kakho and Douglaswakkh. This communication is disappointed. If you can read your views on this issue, I will be very happy. "

This is indeed a wonderful issue worth exploring. This problem is located at the junction of the limits of science and the risk/return/dangerous scene, which has the possibility of completely unknown. In the face of this issue, the entire society, even the future of all human beings may be at stake.

If smart alien creatures really exist in the galaxy or the universe, then they may be detected through different signals: electromagnetic signals, planet transformation signals, or because they are flying in space. But so far, we have not found any evidence to prove that there are planets with aliens living. We may be really lonely in the universe, but the most honest answer is that our understanding of related possibilities is not enough to give a certain denial. (Ryan Somma/Flickr)

The greatest hope and fear for the first contact with aliens lies in what kind of scenes will be, what will they look like? Although we will not know these before they really discover them. There are currently five major possibilities for how we discover extraterrestrial creatures on one day in the future.

The first: we found in the backyard of our universe simple, like microorganisms. By discovering petrochemicals, dormant, and even active life that comes from the earth. They can be in the solar system, or just pass through the solar system. Exploring tasks, or lucky to get a material that landed on the earth and contains life, can make this discovery come true.

The second: we indirectly discover signs of life on the planets or satellites in other scholars. By direct imaging or Lingri spectrum, we can identify the characteristics of life planets and draw conclusions. The most likely explanation is that it has life.

Third type: We received and decoded a technological signal sent by an advanced external civilization. Regardless of whether it is reached through the radio wave band, another electromagnetic frequency, or through the signal we have not cracked (perhaps from high energy neutrinos). The scientific exploration made by the Institute of Civilization (SETI) will be discovered first.

Fourth type: We received direct visits by aliens. Those who study the UFO incident hope that in the gap that has been recognized and witnessed but has not sufficient resolution to expose the facts, a spacecraft from smart alien creatures is waiting to be discovered.

Fifth type: Oh, maybe aliens are waiting outside, but they have not actively spread their news. They are waiting for the first information from alien civilization. So we need to send it so that they can receive it.

For a long time, scientists are pursuing the first three possibilities and will continue to study in this direction. The fourth possibility has also continued to attract a large number of pseudo -science and conspiracy theories, although many recent efforts have been put in this state. The fifth possibility pushed our greatest hope and deepest fear to the front line.

For foreign stars, the most ideal planet should be a planet with the size of the earth and the quality of the earth. This planet is similar to the distance from the stars surrounded by it and the distance from the earth to the sun. We have not found such planets, but we have speculated how many such planets may have in our galaxy. We must pay attention to distinguish the biological characteristics we think. For example, oxygen, oxygen needs to be divided into oxygen generated by life and oxygen generated through inorganic processes.

Of course, we hope that at least one other smart civilization will be born at a moment of the galaxy. Like us, they have obtained advanced technology and began to search for things outside in their own attachments. They are curious about what they can or find.

Maybe they already know the answer that is still confused about us, such as: What is the secret of sustainable nuclear fusion? What is the overall policy of solving energy problems? How their races overcome internal fighting, accumulation of resources, excessive consumption, and global war to maintain their survival on the mother star. But maybe they have made every effort to search for possible technical characteristics, and they have not been found for a long time, which gives them abandonment. Perhaps the only reason to prevent them from contacting us is that they do not know that we are here, and they have not actively spread their news, and they have not preached their existence. If this is the case, maybe all we have to do is to announce: we are here!

Once our signal reaches their position -a few light years or tens of thousands of light years -they can send a signal, or even manned task. Affordable answering the answer we look forward to: Yes, there are other smart aliens, we are here!

This photo was taken in 2011 (now 11 years), showing the coverage of human radio signals in space. One light years is a long distance. But the average distance of stars in our solar system is tens of thousands of light years. After so long, the signal we launched has reached about 10,000 stars. (Abstract Goose)

Of course, every hope is to wait for fear. Fear is not that there is no other life outside that can receive our signals, not that aliens hear our voice and choose to ignore that we refuse to reply. It is not afraid that everything we do is futile. Before the signal we sent is covered by the background of the cosmic noise, the threshold of alien civilization has not been touched. On the contrary, what we are afraid of is that aliens really receive this signal and drive at us with maliciousness. We are afraid of a predatory alien civilization -have a lot more advanced technology than us -conquer us in the future.

Considering the technical gap that will definitely exist, because they may lead us for hundreds of years, thousands of years, or even millions of years. This will be a short and cruel war, and finally ended with human beings or slavery. Just like the plot of many aliens invading movies. Without enough unrealistic victory for brave people, we may be destroyed by ourselves.

In this photo, a white receiver cone (part of the antenna receiver) of an antenna is being moved by the crane. Human beings not only have the ability to detect electromagnetic signals from the universe, but also send and broadcast these signals. (CSIRO)

Of course, since the first radio station and TV signal have been transmitted, they are powerful enough and have a suitable frequency, which allows them to penetrate the Earth's atmosphere ionizing layer and Van Alan radiation belt -humans have been intentionally interested in about 80 years, and have been intentionally interested in in about 80 years. Or inadvertently declare our existence to more advanced external civilization. If we use the earth as a sphere with a radius of 80 light years, we have discovered about 10,000 star systems within this range, most of which have not been found today. Affordable signal.

There is a difference between what we have done inadvertently and the things that we will continue and work together to explore the things that may exist outside the galaxy. The main idea belongs to "Meti: Sending information to the outside world". It is sometimes called "active search for the Outreach Civilization Program (SETI)" because it does not simply listen to it, but actively spreads, including targeted at the target Sexually spread signal to the star system that is particularly interested. It was this behavior that attracted people's attention, and criticism and attention.

Corresponding to looking for alien smart creatures is to send them messages: Meti. By designing and spreading a kind of good -looking, intelligent information to try to get in touch with alien civilization, we may receive a civilized response, otherwise it may not be interested in our planet. (Meti International)

As far as we know, we have gone much farther than most of us decades ago. In the early 1990s, we only guessing evidence proved that planets outside the solar system existed. We don't know how many planets of the earth are surrounded by solar stars; we don't know which types of planets in the universe are common and which are rare; we don't know that our solar system is typical, unusual or rare in the universe. Essence By 2021, many things have changed.

Our galaxy has about 400 billion stars, and we are just one of about 2 trillion galaxies in the universe. Stars in our galaxy:

80% -100% of stars have planets and planetary systems around.

About 20%of the stars are like the sun, belonging to the K, G or F subtype,

10-20%of these planets are similar to the earth in terms of size and quality.

Among them, 20-25%of the galaxy is a planet, which we call the "livable band", which means that if they have the atmosphere of the earth, their surface will have a temperature suitable for liquid water.

With all these patching together, we will find that there may be billions of potentially living in our galaxy: they have conditions and ingredients suitable for life. There are many possibilities in the universe, but we still don't know a lot, which makes us very uncertain about an ultimate problem: how many smart and technical civilizations are there in the universe? How many spacecraft and advanced civilization methods are there. But before we know how to estimate these parameters, especially those parameters that appear under the "F_BT" umbrella, we still don't know at all, we are just guessing possible answers. (University of Rochester)

According to the New York Times, everyone -including Kakamo and Douglaswakh -Both believe that as far as intelligent life is concerned, it is true that human beings are the only idea. After all, we still don't know the answers to the three major questions.

1. In a world we think may be livable, how many already exist or have life?

2. In the world of life, how many worlds have maintained themselves on the time scale of the universe, such as billions of years, thus evolving into complex, multi -cell, or highly differentiated creatures?

3. In a world where life survival, prosperity, and complex, how many worlds have really become intelligent and technical?

There are billions of planets that may live in our galaxy, which is inferred by the situation we can measure. But we must face our ignorance calmly. If the answers to these three questions are around 1%, then smart life has appeared thousands of times in our galaxy in the past. If the answers to these three questions are 0.01%or less, then we may be the first person in the entire galaxy to reach so far.

The fact is that if there are no more high -quality information about the universe, we will not know, but if any of these three steps is "difficult", then human beings may really be lonely.

If an alien spacecraft arrives on the earth, the imagination illustrations when they first come into contact with us. What we are most worried about is that aliens will be hostile to humans. They will come to our planet and seize any resources we think of valuables, but do not consider our own existence. (Andrés Nieto Porras)

To facilitate discussions, let's imagine that if there are other smart civilizations. Should we try to contact them? Canada Daoxiong said no and controversy -I made this debate very fierce -he said:

"I think that promoting our existence to the outside world is a catastrophic bad idea. In fact, I think that contact with an opponent who knows nothing about us will be the biggest mistake in human history. The civilization collapse we know. It may happen ... assuming that aliens are peaceful, they want us to benefit from their technology, this idea is naive, because they are more likely to be like Cordus. "

Then, assuming that aliens are like Cordus: to conquer and wealth. Not the wealth of gold, but the precious resources we can dominate. Frankly speaking, this is the biggest problem of this argument: if an alien species can cross the universe and has mastered the complex technologies such as Star Travel, then they exist on the earth instead of rare resources. Woolen cloth?

There is nothing. Everything on the earth is not unique. They are easy to synthesize elsewhere, perhaps except for smart life itself. We must assume that an advanced alien civilization will only be interested in us, because we announce our existence and then act quickly without any reason to destroy us. "Maybe they feel that stepping on these technologies on these technologies The creatures in the 物 还 are very interesting. "It is like a child may use a magnifying glass to burn the ant alive to death.

The earth will emit electromagnetic signals at night, but to shoot such images from outside the light, a high -resolution telescope is needed. However, an alien civilization with interstellar travel must have the ability to have this telescope, at least it can detect the small amount of light from our planet at night: this is a clear technical feature. (NASA ’s Earth Observator/Noaa/DOD)

On the other hand, Wakakh's opposite view is the only way to ensure that the universe "lurker" is the only way to ensure that it is isolated in our island world, rather than add any civilized dialogue that may occur. To sum up in his own words:

"Some people will say, okay, wait, if they already know that we are here, what's the point of contacting us?" We are trying to test the so -called zoo hypothesis ... (Imagine we are in the zoo) We are in a certain Several extent is observing animals. We know that they already exist. We passed by a group of zebras. One of them turned to us, looking straight at our eyes, and began to knock out a series of quality numbers with hoofs. I don't know now. Maybe, you have to look at the horses. I want to stay here and try to communicate with this Zebra. "

I don't believe it too. If an alien civilization discovered our planet and concluded, "Well, it must have lives in life", then it will be very eye -catching over the past few hundred years. The rapid changes in our atmosphere, the increase in carbon dioxide, the existence of artificial chemicals in the atmosphere, the appearance of visible light (artificial) lighting, and the emergence of radio signals at night. The presence. Of course, if the zebra shows a very smart side, we will be shocked, but that is because we have not only studied the zebra, but also studied many other animals, and have various indicators to evaluate their intelligence.

Unless one of the two choices is correct:

1. The aliens are lonely and have been waiting to talk to others,

2. Alien is waiting for us to achieve some kind of "achievement" -just like the Volker civilization in Star Trek "before contacting us for the first time, we have been waiting for us Before appearing,

We have no reason to believe that after the thoughtful broadcast, we will complete anything that we have not completed by the signal we have not sent so far.

The crashing alien spacecraft in "X File", as the propaganda film of the tenth season, represents our hope and fear of contact with alien smart species. Although how many of us are "willing to believe", there is no evidence that whether it is good or bad, there will be other lives to contact us. (X-FILES / FOX / Rodrigo Carvalho)

Of course, this is completely a speculative thinking exercise, mainly driven by our own imagination and the knowledge of the events on the earth. However, whether the smart aliens exist or not, whether their intention is malicious or goodwill, there is a fact that there is a fact: although we are facing many problems on the earth -some are caused by ourselves, and some are from external pressure- - No evidence shows that other lives will come to save us.

No other life will solve our energy problems, our resource management problems, our unsustainable treatment of the environment, or issues such as war, hunger, nutritional insufficient or water crisis. Without other lives, we can help us learn to cherish each other's lives and even our own lives. If we want to be liberated from the problems we are now facing, we must look inward, look at ourselves, and look out: not to look at the stars, but to see each other. In this world, the biggest resources we have is our ability to accumulate knowledge and cooperation.

There are raw materials, but what we have to do is to put them together and use them for everyone's interests. If we want to change our human trajectory, seek knowledge, and find a real answer for our deepest questions is definitely an important part of the solution. But for unknown things, we can neither depend on hope nor depend on fear. On the contrary, we must rely on the most important resources: the understanding of our common humanity.
