An Argument in Favor of the “Cosmic” Nature of Humans Has Been Obtained

Additional evidence of the terrestrial life development theory, based on substances from outer space, was received by specialists from Samara University together with their colleagues from the same research team. They found that lactic acid, a compound important for metabolism, can originate in space ice. The results are presented in Journal of the American Chemical Society.

In the Universe, the most common chemical elements are hydrogen (H), helium (He), nitrogen (N), carbon (C) and oxygen (O). On the basis of four of them, terrestrial “carbon” life is built: 65 % of oxygen, 18 % of carbon, 10 % of hydrogen, and 3 % of nitrogen are on agerage contained in the body of an adult as part of various organic compounds, while the remaining 4 % fall on other atoms, said scientists at Samara National Research University.

Ivan Antonov, Associate Professor at Samara University’s Department of Optics and Spectroscopy, stated that separated atoms and structurally simple substances must match in space and have a certain external energy exposure, for obtaining organic “components” of an organism from them. Herewith, as the scientist added, it is hard to detect such molecules in outer space by using modern astronomical methods, therefore, proving the theory of “introducing” the first organic compounds from outer space by observations alone is difficult.

Specialists from Samara University together with their colleagues from the USA have obtained evidence of the possibility of lactic acid formation in outer space, a substance that, among other things, originates in muscle tissues during intense trainings. The study confirms that lactic acid can be formed from simpler substances with fewer bonds.

“We have proved that when exposed to cosmic rays, ice consisting of ethyl alcohol and carbon dioxide actually transform into more complex molecules – lactic acid and carbonic-acid monoethyl ether, a substance of the same composition, differing in structure and chemical properties. The compounds we have obtained are very interesting for observational radio astronomy, and our evidence of their formation gives astronomers a clue as to what other molecules can be found in outer space”, explained Antonov.

According to the expert, in this area, there are very ambitious tasks – finding and experimentally testing the mechanisms of forming biomolecules (building blocks of proteins, fats, carbohydrates and nucleic acids) of key classes out of simple molecules in conditions of outer space, under radiation exposure.

“Implementing these tasks can greatly change our understanding of the life origin: shifting the focus from the Earth to Outer Space, it will shed light on the life formation processes in general, as well as on the question: are we alone in the Universe?” added the scientist.

The study was conducted by using the unique scientific facility for studying chemical processes in deep space conditions, created at the Centre for Laboratory Astrophysics of the SB LPI, supported by Megagrant No. 075-15-2021-597.
