Why is life based on carbon?

Everything on Earth consists of carbon and will consist of it for the foreseeable future, but can life in other parts of the universe be based on another substance?

It's amazing to see the forms of life that are featured in the films and the leading series, such as "Very Strange Things", "Annigation", "Acception" and "Love, Death and Robots." These creative new worlds create our curiosity and desire to see if such things really exist.

What makes carbon so special?

Carbon is a small kid in a class that is very social and very easy to get close to.

The 4 electrons in its outer shell are open to exchange with anyone. Carbon is easily covalent with other elements because of its small size, and the molecules and compounds it forms are extremely stable. The quadruple of carbon and small size make it special, so it uses every opportunity to complete its octate and become stable.

Catenation forces carbon to form an unusually stable chain, inflammation, and ring structures. It not only links to another carbon, but also creates strong links with hydrogen, oxygen, nitrogen and many other elements, all of which are necessary combinations as the basis for life. The strength of the carbon link varies depending on the direction of its connection and the element with which it is connected. Electro-positiveness, chirolity, melting and boiling temperatures, distance between kernels, gravity forces and many other chemical and physical properties play a role in stability and reaction capacity.

Why not silicon or any other element?

The closest element to "social" carbon is silicon, but silicon is large and slightly introverted. Even though silicon belongs to the same group as carbon, it is not able to form strong and stable links with itself or other elements, especially hydrogen. If it forms sustainable connections, they are not as diverse, flexible and complex as carbon. Silicon responses are also slower than carbon responses.

Biochemistry also plays an important role in this argument. CO2 dissolves in our blood and helps maintain the pH of blood, and plants use it for photosynthesis to produce oxygen that supports other life forms. Now imagine that you're breathing SiO2, which is a crystal... it doesn't seem very easy.

However, some diatomic algae living in the ocean do contain silicon in their system, but it is not the same as self-replicating carbon DNA and RNA, one of the main biomoleculars of living creatures.

Is life possible on the basis of any other element?

At least life on Earth will remain carbon-based.

The flexibility, stability and ability of carbon to create polymers make it almost the ideal building block of life on our planet, and from a chemical point of view it seems almost impossible for silicon to replace carbon, especially since silicon is toxic to some living organisms.

The essence of life lies in building blocks of proteins or similar compounds, and metabolism and genetic material. We know this because of what we have seen on Earth and in its forms of life.

It takes a lot to create life, and this article has only touched on the tips of the iceberg, and it is disappointing that we will have to be content with science fiction films about our non-carbon forms of life, but we must not give up on our scientists and researchers who are constantly trying to go beyond our carbon existence.
