Researchers in chemistry from the University of California at Berkeley and the University of Hawaii at Manoa have decided to completely destroy conventional ideas about the creation of human civilization. Scientists were able to simulate in the new experimental conditions in deep space, showing that the complex building blocks of life may have been created on an icy interplanetary dust, and then fell back to Earth, giving impetus to the emergence and development of living organisms.
According to experts, they were able to prove that in the space to create the conditions capable of challenging dipeptides, which are bound pairs of amino acids that are formed in outer space, and then fell to earth. In particular, we were struck by the cosmic origin of almost all building blocks of life are present on Earth - said Richard Mathis, director of astrobiology.
With this theory, we can prove that life on our planet came on board such a space body, like a meteor or comet that could catalyze the formation of enzymes, proteins (polypeptides) and more complex molecules (sugar, for example) - the substances necessary for the origin of life.
Due to the fact that the fallen meteorites, scientists have detected only the basic organic molecules, it was assumed that these preconditions for the emergence of biological forms in the world is not enough. Origin of life due to more complex molecular structures. Ultimately, the researchers came to the unanimous conclusion that the complex chemistry of life appeared in the Earth#39;s oceans.
To prove their theory, the researchers of the University of Hawaii have created an artificial comet in a special reactor to space conditions - a large number of cosmic rays, low temperatures and vacuum. In the center of the celestial body of the reactor is small dimensions - a conglomerate consisting of frozen water space dust dioxide, ammonia and other components comets cooled to 10 Kelvin (-263 ° C).
From time to time, scientists simulated the solar wind from the young Sun and cosmic rays bombarding the comet using beams of high-energy electrons and other charged particles.
As it turned out, the comet is produced after each impact, sufficient materials and complex molecules (nine different amino acids and at least two dipeptides), who were able, by the scientists, give rise to the development of life on Earth.
