What other forms of life are there besides carbon based life?

Specific concept, activated carbon adsorption method is the use of porous activated carbon, so that one or more substances in the water are adsorbed on the surface of the activated carbon and remove the method, the removal of objects including dissolved organic substances, the synthesis of detergents, microorganisms, viruses and a certain amount of heavy metals, and can decolorize, deodorize, air purification. Activated carbon, sulfonated coal, zeolite, coke, etc. are commonly used adsorbents in water treatment, and the activated carbon lattice forms developed pores of different shapes and sizes after activation, which greatly increases the specific surface area and improves the adsorption capacity. The effective radius of the fine pores of activated carbon is generally 1-10000nm, the radius of small pores is less than 2nm, the radius of transition pores is generally 2-100nm, and the radius of macropores is 100-10000nm.

The pore volume is generally, and the transition pore area is generally; The macroporous volume is average....

In the text, Asimov proposes 6 life forms:

fluorinated silicone organisms with fluorinated silicone as the medium;

sulfur fluoride organisms using sulfur as a medium;

water-mediated nucleic acids protein (oxygen-based) organisms;

Ammonia-mediated nucleic acids, protein (nitrogen-based) organisms;

methane-mediated lipid compound organisms;

Lipid compound organisms with hydrogen as a medium.

Although our astronomical technology is relatively advanced now, there is still a lot of room for improvement. To improve the universe as we see it, we must continue to develop at this level of technology.

Because life on Earth is based on carbon, it is through this element that life is constructed.

1. Carbon-based organisms: organisms that use carbon as the basis of organic matter. All living things known on Earth are carbon-based, including humans, based on carbon and water.

2. Orbital-based organisms: life composed of substances mainly containing silicon and silicon compounds.

In terms of material composition, all living things on the earth are basically composed of similar substances - basically composed of carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, calcium and other elements. These elements combine with each other to form small molecules of life such as amino acids, nucleotides, and glucose; These small molecules are then combined with each other in a special way to form biological macromolecules such as proteins, nucleic acids, polysaccharides and lipids. These molecules become the basic "bricks" on which life is built.

Because these important biological macromolecules that make up these lives are based on carbon skeletons, researchers call such life "carbon-based life".

Carbon-based life is an organism that uses carbon as the basis of organic matter. Silicon-based life refers to life that is composed of substances mainly containing silicon and silicon compounds.

Silicon-based life is relative to carbon-based life. The so-called carbon-based life disturbance ruler is rooted in the original concept of organic matter: substances that can only be produced by living organisms, and such substances known to humans in the past contain carbon elements; It was later proven that "organic matter" could be synthesized by chemical methods.

Although "organic" has been used as a historical concept, carbon is no longer seen as an essential core element of life. As a result, "non-carbon-based life" with silicon, boron, or phosphorus as the core elements rather than carbon as the core elements has been proposed.

From the perspective of the composition of matter, all living things on the earth are composed of basically similar substances - basically composed of carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, calcium and other elements. These elements combine with each other to form small molecules such as amino acids, nucleotides, and glucose. Silicon-based life can also be defined in this way:

Life is made up of substances mainly containing silicon and silicon compounds.

Carbon-based life is an organism that uses carbon as the basis of organic matter. All living things on Earth are carbon-based, including humans, and they are all based on carbon and water. Because the proteins that make up carbon-based organisms, such as purines and pyrimidines, which are genetic materials, are hydrocarbon derivatives, they are called carbon-based organisms.

Silicon-based life is a life form other than carbon-based life, that is, life composed of substances mainly containing silicon and silicon compounds. In terms of material composition, all living things on the earth are basically composed of similar substances - basically composed of carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, calcium and other elements. These elements are combined with each other to form small molecules of life such as amino acids, nucleotides, and glucose.

Logically, in the infinite universe, extraterrestrial life forms will certainly be ever-changing, not necessarily like us earthlings. On the path of exploring aliens, humanity can only start from scratch. Perhaps in the near future, we will indeed discover the existence of fraternal civilizations like ourselves, when it will be too late to join forces to explore other life forms in the universe.

I guess almost all the questions about whether there are aliens give us a definite answer, what is the size of the universe, we can't be exact on this question, but we have no choice but to use the word infinite to describe it.

First, we will find that carbon-based life on Earth is also in this rangeTheoretically, these life forms may exist in a specific environment. Moreover, the civilization of the earth is still at a very rudimentary level, and there is very little knowledge about the universe. Therefore, there is every reason to believe that there will be more forms that we do not know about in addition to the life forms that may exist theoretically, such as gaseous and liquid life, and even pure energy bodies separated from matter.

If you can't keep up with your meals, you'll have to stop and go.

2. According to examples, there are currently a large number of nuclei on Earth. These nuclear ** can destroy humanity many times. In fact, their power is not the shock wave generated by **, but the overall damage to the ecosystem after the end of the nuclear war, such as nuclear radiation and nuclear pollution.

But why doesn't anyone use it, because as we all know, once the nuclear ** is used, people will not have delicious fruits. But what if the people of the nuclear countries on this planet are not at all afraid of nuclear radiation and pollution.

3. It is well known that our planet and even the sun,None of them are forever there. One day, humanity will face an irresistible catastrophe. Until then, if humanity does not look for a new home, nothing but destruction awaits them.

Finding a suitable Earth for carbon-based life to survive, even if there are no aliens on Earth, will leave a way out for the future of humanity.

This is a preconceived notion that extraterrestrial life is almost the same as ours.
