If aliens really come to earth, what do they want to plunder most?

The imagination of writers and screenwriters about alien invasion of the earth is dragged down by the level of scientific literacy. We often regard some things that we regard as treasures as the objects of high-level intelligent life coming to the earth hundreds of millions of light-years away to plunder.

The lower class will point to things like gold and silver treasures, and even treat the 7 billion people on the earth as coolies; A little better will define treasure as a livable earth; People with high scientific literacy may point out that the earth and human beings are not resources, so aliens can only establish friendly relations with us when they come to the earth.

But as far as I know, there are really treasures on the earth, and they are very, very precious. Even if you travel through the whole galaxy, you may not be found. If there really is an advanced alien civilization, they will certainly not let go of such precious wealth. Then what is this wealth? How will aliens "plunder"? This is today's theme.

Resources are not precious.

First of all, we need to know, if there is an advanced alien civilization, what will they think of "treasure" and what can be called "treasure"?

Our earth is condensed by cosmic dust, and there is nothing special. These elements are well mastered in the universe, and many resources that are scarce for us now are not rare, such as energy.

In the past hundred years, we have always heard the argument that "the earth's energy is only enough for human beings for decades" in different channels, but the fact is that the remaining time for the exploitation of petrochemical energy has increased over the years. Why is this? It doesn't make sense. With the progress of civilization, human energy consumption is accelerating, but why can there always be an inexhaustible phenomenon?

That's because the speed of human exploration of energy is faster than the speed of mining, and there has been an incredible "reverse growth".

Of course, petrochemical resources will eventually be replaced by more advanced energy, which naturally gives us a fairly high upper limit. I believe many people have heard of clean energy, that is, wind energy, solar energy, hydro energy, bio-energy and so on.

But you must not know that the above four are actually solar energy. The source of wind is that sunlight heats the earth's surface, causing air to expand; Water energy is also the evaporation of solar heat, which causes water circulation in the earth's atmosphere, and water vapor is "carried" to a high place by thermal energy, thus storing gravitational potential energy. Not to mention bioenergy, photosynthesis, photosynthesis.

So how much energy does the sun give the earth? It is about 3.7668 million Ejiao every year. How big is this number? The fixed energy of photosynthesis of all plants in the world is about 3000 angstroms, and all production and consumption activities of human beings today will cost about 500 angstroms.

Well, the utilization rates are 0.79% and 0.0 13% respectively.

If all the energy from the sun can be collected, it only takes 1.5 hours to support the human expenditure for a whole year!

Before the industrial revolution, almost all human energy came from plants, so we need to try our best to find ways to scoop more water from the 3000-angstrom pool. Now, humans have discovered a piece of Wang Yang Sea behind the pool. What we need is to speed up the technical upgrade and replace it with a high-power pump.

Besides sunlight, we can also develop nuclear energy and gravitational energy, and the reserves of these energy sources are terrible. It is not an exaggeration to say that it will never be exhausted. No, it will never dry up!

There is an upper limit to the consumption of resources by civilization.

And the consumption of resources by civilization is not endless. A lot of things we think are infinite, just because we haven't touched its upper limit. To this end, I can give another example: population.

When I was a child, I often heard such propaganda-if the population is not controlled, the population on the earth will explode in a few decades, and there will be less than four people standing per square meter.

This is a typical assumption. These "gods" regard human beings as bacteria in Petri dishes. As long as they are given enough conditions, they will continue to multiply. They have established a seemingly watertight logical chain-the population will be controlled because of the lack of food in the past, and it will surely usher in explosive growth after industrialization eliminates famine.

But in fact, this is simply the reverse of cause and effect. It is precisely because famine always reduces the population that families need to constantly replenish the population. After entering the well-fed modern society, human fertility will be greatly reduced! Many developed countries have experienced negative population growth, and people are more willing to put resources into the present quality of life after their children lose their old-age security function. That is the reality.

Therefore, if there is advanced civilization, it must be extremely rich in material life. A civilization that can complete such an exaggerated interstellar voyage has no reason to even solve this problem that mankind is about to solve. In fact, according to the current development speed, in the near future, mankind will surely usher in an "energy freedom" revolution, and abundant energy will make the earth civilization enter the next stage of rapid development, and then mankind will develop the possibility of interstellar navigation.

The earth is unlikely to be an ideal colony.

The earth's environment seems to be a valuable asset in the universe, but it is not. First of all, an environment friendly to human beings is not necessarily friendly to alien life. Imagine a vibrant planet, the whole ocean is liquid ammonia. Do you really want to immigrate there?

Secondly, by observing and estimating the number of life in the universe, we can find that the number of planets suitable for life must be far more than those with intelligent life. Even if aliens need a suitable home, there is no need to pity the earth people. The earth is fine, but it must not be an orphan in the vast universe, and it is meaningless to be emotional.

Finally, we have no idea about the form of advanced civilization. Some scientists have pointed out that human beings may continue to exist for less than 1000 years. In the future, human beings may get rid of this fragile and short-lived body and become a combination of artificial intelligence and advanced design. By that time, the meaning and needs pursued by "human beings" are unpredictable. Just as the ancients 500 years ago did not understand that they could not leave the elevator when they left home, it is impossible for us to guess what a high-level civilization really needs.

Do you understand the absurdity of alien invasion in literary works now? It's like when you meet a dog on your way home from work. You glance at it and it wakes up and grins at you, for fear that you will rob it of its delicious dinner and a rotten bone. ...

Life is a treasure house of knowledge.

So ... what is the so-called treasure, and how will aliens "plunder" it?

Now, let's put ourselves in the shoes. If it is set to unfold like Avatar, we human beings are advanced civilizations, have extremely rich materials and energy, and have developed interstellar navigation, then what do we want most from the universe?

No, actually, this is what we have been doing. Humans have been tirelessly looking for extraterrestrial life, not only intelligent life, but life itself is exciting enough!

Yes, we want to know whether there are other possibilities besides the known life forms on earth; Whether there are substances capable of genetic function except nucleic acids such as DNA and RNA; Besides organic matter made of carbon, are there any other elements that can be the cornerstone of life? ...

This knowledge is not available in many experiments, and it is impossible to simulate and calculate by any means in the future.

Because they are the precipitation of billions of years, they are very hard, and they can't cut corners, and they can't find any knowledge of shortcuts ... You know, the number of layouts that can be placed on a 19× 19 Go board is much more than the atoms in the whole universe! What's more, it is the interaction between countless molecules.

I have been thinking about a problem since I was a child. Some electric fans will be dirty if they are not cleaned for a long time. There is a layer of black ash on the blade. I used to think that these ashes stuck tightly until one day I touched them myself. ...

Very loose. How did such loose ash stick to the fan blades that rotate so fast?

Later, I realized that this is actually a process of choice. All the dust that can't stick has flowed out, only the dust that can stick is left. During years of operation, electric fans have found dust that can be attached to the blades without being thrown off.

Is there any other way to find those "different" ones from a handful of dust?

And this life screening, a selection of 4 billion years, the mystery of life on earth, piled up with the age of the universe 1/3!

Molecules that perform various functions in life, how they accomplish their functions and how they interact with other molecules. How is the balance in life achieved and the transmission of information realized? This knowledge can be said to be close to infinity. Every time you know more, you will open up a new world. The final answers to these billions of years of choices are so exquisite that scientists even doubt their sources.

As far as human beings know about life now, it is only the first page of this gobbledygook. There are too many mysteries waiting for us to study, understand and explore their value. They are the most valuable source of knowledge in this universe.

Yes, the "treasure" of the earth is a complete collection of all life that has multiplied on the surface of the earth for billions of years, from every microorganism to the mystery of the human body. They are all the most valuable sources of knowledge and the most advanced research materials in this universe. If aliens find the earth, they will be overjoyed. This is a miracle star that has flown over10 billion planets, and may not find one! I'm worried about catching your biopsy to calm down, just as 20 19 makes people swallow feces to treat tuberculosis.

Protect the most precious resources

So, the last question, why should we protect wild animals? There are a lot of propaganda that will use people's sympathy to describe the killing of wild animals as very pitiful, but this will undoubtedly fall into a logical loophole-stray cats and dogs look more pitiful, why don't we protect them?

The real situation is actually like this-every extinction of animals is equivalent to losing a treasure house of knowledge accumulated over millions or even hundreds of millions of years! At present, the research on human life is too shallow. If these rare creatures can be preserved in the future, they may unlock vast amounts of knowledge in the hands of our children and grandchildren, and may even have key knowledge to solve the current human predicament! It is reckless to eat such precious resources and squander them in a temporary appetite!

So I must appeal that protecting wild animals means protecting the future of mankind. They are very important and rare resources for human beings. Please don't put them on the table again!
