I don't believe it. Because I think life is based on carbon, and it is impossible for silicon to form life, I don't believe it very much.
-
I don't think NASA has said anything like that, maybe it's just a rumor. Aliens have never been to Earth at all.

As we all know, NASA is an abbreviation for National Aeronautics and Space Administration. The agency is far ahead of the world in the exploration of outer space. In the last century, the manned moon landing was successful, and many famous probes were launched, such as Voyager 1 and 2, Pioneer 10 and 11, New Horizons, Cassini Huygens, Parker Solar Probe, etc., so it is believed that NASA has the most detection capabilities.

Many people may have heard that extraterrestrial life must beCarbon-based organisms, so why can't they be other types of creatures?First of all, we need to know what carbon-based organisms mean! Perhaps some people don't understand that as far as all known life on our planet is concerned, everyone has the common attributes of carbon-based organisms.
In other words, whether humans or other animals, we are one of the organisms that use carbon as an organic matter, our amino acids.
in the carboxyl group. and amino groups are both attached by carbon.
Scientists say that planets must have "volatiles" in the atmosphere for life to sprout, and the volatiles here refer to carbon dioxide.
and water, which can lead coarse trails to boil at lower temperatures. In addition, as far as we currently know, any life form must have carbon and water to maintain its chemical growth. It is the chemical properties of these substances that prove that life on any planet in the universe must depend on them for survival.
Of course, planets must have volatile substances, but this does not mean that planets can have such conditions from the beginning of their formation. When a star is in the early stages of its life, its light can bake dust across the region. Later, the habitable area of the star also slowly changed from this process.
Eventually, it became suitable for cold and warmth, and the locust and dust became planetary. In the course of the research, scientists.
Accidentally spotted the right amount of asteroids and comets in stool shirts.
impact, which will also help a planet to become a planet with volatile substances.
When humans look for extraterrestrial life, they have to look for carbon-based life.
living environment and biological form. From sifting through habitable zones, habitable planets to finding liquid water and primordial soups, it's a shortcut in the scientific sense. Instead of blindly searching for those imaginary extraterrestrial life.
While sci-fi and religion may not buy it, or even constantly question it, it doesn't matter. Maybe 10,000 years from now, science will lead mankind to really find the life that science fiction ** and religion say?! Of course, this is the best.
However, living in the present, our science must start looking for extraterrestrial life from the most familiar and reliable places. Because this is the shortest path.
-
This is because there is only one form of life that we humans have discovered so far, and that is carbon-based life; All of Earth's biological clocks belong to this type, so even if there is extraterrestrial life, this type of high-altitude life is the most likely.
-
Only in this way can it be proved that life on other planets is the same as humans. The reason is that all life on Earth is made up of carbon-based life, and if carbon-based life can be found on the wide ball of Hoshiga, which is sold at a loss, then it proves that there are also life on this other planet.
-
Because everything on Earth is made up of carbon-based life. How to find the planet There is no sail brother in it, so people can't be confined to this only planet.
-
Until now, all life on Earth has been carbon-based, which has become the basic building block of life.
-
Will humanity finally be able to find an extraterrestrial civilization?All I can say is that the probability is more than zero, but how much is higher than zero. I can't say for sure. This is a very, very unlikely view.
It's likely that some people disagree, or will continue to swear crookedly. But if you do have even a small amount of innovation, please read the following analysis carefully, which will be my most specific analysis of extraterrestrial civilizations. Planets are known as space islands, and they are home to planetary agglomeration3.
The family of our solar light is the cosmic space island of the solar system, which includes about 400 billion planets, and the sun is only one of them. The Milky Way is about 200,000 light-years in diameter and is a vortex planet, also known as a barred spiral galaxy because of its key to a very shiny rod-shaped structure; The vortex of the solar system has two key overhangs and two supporting arms, and these larger overhangs are all more concentrated areas of the planet, and the sunlight is located on the arms called the hunter's arms about 10,000 light-years away from the key points of the solar system.
The observable universe has the potential to contain 10 trillion planets, and the observable universe is only the scope of the universe that can be observed by the limits of human physics, and beyond this range, there is an even larger unobservable universe. Therefore, how big the universe is, human beings cannot judge it now. However, the positioning of the universe in the basic theories of modern physics is informational, good from the beginning to the end, and relatively limited.
Even the planets of the solar system are 1 light-year away from each other. Academics in the thirties of the last century have analyzed the long boundaries of planets in the solar system.
There is an Oort cloud containing the planets of the solar system, which is composed of meteorites and floating dust, and there are trillions of meteorites over there, which is the origin and concentration of comets. But it is still surmised that the larger Hubble telescope will not be able to see all the meteorites over there. Experts have now used survey glasses to scan millions of planets, and so far they have not seen any advanced civilization.
Because in our TV series, only high-level civilized behaviors can change the brightness of the planet, which is discovered by everyone; And civilized behavior like everyone human,Even if there is, you can't find it.
-
It's not big, it's too hard to find aliens in the universe. The reason is that the universe is so big. Cosmic civilizations cannot get in touch with each other through the vast space of the universe, and neither of them knows whether the other really exists.
Personally, I think that extraterrestrial life is very likely to be carbon-based life forms.
-
Personally, I think that the possibility of humans finding aliens is very small, because the galaxy is so far away from us that our current technology has not yet reached the point of fully exploring the galaxy.
-
The chances of us humans being able to find aliens are very small, about 10%; It is impossible that aliens will not be the same as us humans.
-
At present, no extraterrestrial life has been discovered, and it may be discovered that it has not been announced, because there are so many galaxies in the universe that only the Earth can give birth to life, I don't think it is possible.
Is there any extraterrestrial life?
The vast majority of people have always believed that extraterrestrial life would not occur at all. Another group of people, starting from the uniqueness of life on Earth, logically deduces that thousands of stars are likely to appear in space. Not so long ago, an American biologist announced his vision of extraterrestrial life.
He believes that extraterrestrial life and civilized behavior in cosmic space have long since disappeared. The earth is the only star with life, and the history of human development is the only civilization in the universe.
Extraterrestrial life generally refers to extraterrestrial life that appears outside of Earth. This definition ranges from simple bacteria to relatively intelligent alien organisms. The course of scientific research and testing of extraterrestrial life speculation is called extracosmic biology or astral biology.
In fact, people have been using electromagnetic waves beyond Earth and astronomical telescopes to observe potentially habitable planets to detect signs of extraterrestrial life, but so far there is no accurate direct evidence of extraterrestrial life. Some people think that the probability of discovering aliens is unlikely, and there are also many people who believe that extraterrestrial life is inevitable.
What are the circumstances and conditions necessary for the birth of life?
The main criteria for the survival of organisms are the sun, gas, water source, and region. The sun gives kinetic energy to life, gas is converted into kinetic energy, water source is the main criterion for the emergence of life, and the area is an indoor space for biologically themed activities. The necessary condition for the emergence of life is external kinetic energy and its natural environment to ensure the transformation of energy.
The key to life on Earth lies in the sun and water, but it survives with the help of geothermal heating and the sea. The means of transport that you often talk about are unlikely to be able to complete the immigration investment at a high-tech level.
The temperature suitable for the survival of organisms, generally between minus 50 degrees and 150 degrees, is indispensable for moisture. The charm of life chemicals such as proteins and nucleotides is closely related to water. There is no life without water.
The air content is moderate. Although a small number of Pseudomonas aeruginosa have been found to survive without oxygen, oxygen and carbon dioxide are extremely important for the emergence of life, with sufficient light and heat, and electrical energy from the living system software.
-
There is nothing special to discover, the universe is very large, and many planets also have water, and it is very likely that there is life, or other ecological life.
-
This is because there are many galaxies in the universe, so scientists believe that not only Earth can support life, so they do not deny the existence of extraterrestrial life.
-
Scientists have not found anything, but scientists have been studying what is known about extraterrestrial life.
-
Extraterrestrial life is real, he left a portrait on my tree, please look at my head.

Every life form, from plants to animals, exhibits complexity. The first self-repeating organism evolved into more complex biological roles based on the complexity of binding more and more molecular structures. The complexity here refers to the millions of intricate ionic bonds and reactions that are necessary to maintain higher life forms.
Initial life forms such as amoebae, for example, have developed molecular structures that are far less complex than those of higher dairy animals. The complexity of the molecular structure allows some high-end effects to occur, such as inhalation, metabolism, digestion and absorption, and most importantly, reproduction. None of this would have been possible without carbon.
Without carbon, there would be no DNA, proteins, lipids, glycogen, body fat, muscle fibers, or anything else that makes up life.
At this stage, people have seen a table of 118 elements, and it is puzzling why only a few classes of elements are used to make up organic chemical life. Naturally, the most common of them is carbon. Because of the unique thermal and physical properties of carbon, it is superior to other elements.
A carbon atom is made up of four valence electrons, allowing it to produce four single bonds (e.g., methane gas), two hydrocarbon groups (e.g., carbon dioxide), and one triple bond (e.g., acetylene gas). However, the dominance of carbon is not due to its ability to produce such complex ionic bonds, but rather because it is easy and flexible to produce such bonds. In fact, the co-ancestors of carbon in the table of chemical elements all have 4 valence electrons, but the reliability of the bonds they produce cannot be compared with that of carbon.
In the table of chemical elements, below the No. 6 primordial carbon is the No. 14 primordial silicon. These elements can also produce thousands of molecular structures, but the molecular structure of the silicon molecule of the hydrocarbon group is not as smooth as that of the carbon molecular structure of the hydrocarbon group, they are only transient, and their variability eventually drives them to single bonds. Carbon molecular structures, such as nitrogen oxides, are one of the most important types of molecular structures to sustain life, and they are neither too cheerful to dissolve easily, nor too smooth to hinder ductility and adaptability, which allows enzymes to control the carbon molecular structure very easily, making it difficult for silicon-based life to survive on Earth.
Silicon is more oxygen-friendly than carbon, and it also reacts violently with O2 at relatively low ambient temperatures.
This means that the silicon chain or silane cannot be in people's air. If living organisms immediately stored kinetic energy as nitrogen oxides, carbon-based life would not survive because ethane is inherently flammable (e.g. motor gasoline and gasoline). However, carbon-based organisms store kinetic energy as nitrogen oxides such as sugars, lipids, aldehydes and other nitrogen oxides with very different physical properties.
Just when it comes to carbon-based life, it's likely that there are people who are connected to silicon-based life. Whether silicon can become the main building block of life is also a point that many people continue to explore, and at the same time, biologists have realized the corresponding ideas. In the imagination of biologists, the silicon-based material is the key to daily life in silicon-based green plants, and its biological structure is likely to be like glass fibers and filaments connected together, and the middle is connected by tensile muscle parts.
-
There is a good chance that alien organisms have carbon-based organisms, which are mainly carbon and water-based like humans.
-
Probably there are, because they're magical. So, life outside may be liquid or solid.
Each level is a very exaggerated existence, because human beings have not even reached one level in this level, so it is said that these levels are very sacred and exaggerated.
Maybe the price is very cruel, and I don't have my own thinking or something, so I say that.
All this is arranged, I don't know if you have heard such a sentence, although today's science has been very developed, but today's human beings still have not discovered the existence of extraterrestrial life, this vast universe is like a pool of stagnant water, people can not feel any vitality, human beings are a kind of thinking task, we are constantly thinking, why we still can't find external life? Why is it that we have never been able to determine whether human beings originated from **? Some people even suspect that the world in which humans live is a virtual world, in fact, scientists also have different views on this point, he believes that if humans are really in the virtual world, then it may be divided into three modes. >>>More
