For works of fiction and scientific theories followed. Many interesting thoughts about the possibility of silicon life expressed at the time a prominent Soviet geochemist and mineralogist Alexander Fersman (1883-1945 years). Together with his colleague and friend of Academician Vladimir Vernadsky, he justified the astonishing idea of the possible ways of evolution of life on earth silicon. Hypothesis Fersmana -Vernadskogo developed and added to the American planetary astronomer Thomas Gold (1920-2004 years), suggested that at a certain stage of development of the earth’s crust where life could arise silicon is still lurking in the depths of the seething magma.
In 1957, the literary era cream niyorganicheskih beings ended with the release of the novel Fred Hoyle’s «black cloud.» It eminent British astrophysicist described the appearance of the Earth’s near a giant interstellar cloud reasonable. It is virtually immortal being traveling from one star to the other, feeding on the energy of light and thought, exchanging radio pulses between its parts. Together with another cult science fiction — «Solaris» by Stanislaw Lem — «Black Cloud» has become a kind of standard for a long time for hypotheses about the most unusual forms of extraterrestrial life.
In the 1960s and the work of Lem Hoyle gave rise to an avalanche of publications on the most paradoxical aliens. For example, an American pen-Tel fiction Roger Zelazny wrote the story «The passion for collecting,» in which the planet inhabited by intelligent Skvernida stones. Stones gradually grow and gain weight by collecting a variety of atoms and molecules. Having reached a critical size, they explode, scattering all around their nuclei.
Another patriarch of fiction, Clifford D. Simak, made a romantic story, «All flesh — the grass,» where through the space-time rift in the American town in the Midwest penetrate reasonable flowers. In contrast to the predatory Triffids John Wyndham in «Day of the Triffids», these cute creating hope for understanding and help earthlings.
Crystals, magma, clouds, oceans, rocks, flowers — the list of the living and sentient beings could continue for a long time. What is this possible in the vast universe, and that is absolutely incredible? It is time to have its say scientists.
Search for another reason
In November 1961, the Radio Observatory in Green Bank (West Virginia, USA) held the first conference in the history of science on «Search for Extraterrestrial Intelligence» (SETI). Today this abbreviation is familiar to every enthusiast study of extraterrestrial civilizations. After 10 years there is another section of interdisciplinary research — «Communication with extraterrestrial intelligence» (CETI).
At the same time there was an interesting hypothesis of Soviet scientists on the super-conductor based on reason. It was developed by astrophysicist Vitaly Ginzburg. No less original hypothesis in the mid-1970s published a group of French astrophysicists. They examined the unexpected prospect of the existence of «nuclear life» to die after the supernova explosion of a star.
It required the systematization of all these hypotheses dizzy, and a big fan of SETI and CETI Robert Shapiro took up the solution of this problem. This chemist at New York University, wrote a book, «Life beyond Earth: A Guide for reasonable earthling of life in the Universe,» which introduced the original classification of all kinds of creatures in the universe.
On the pages of the monograph Shapiro has plasmoids that exist in stellar atmospheres, beacon inhabiting interstellar clouds, and lavoby magmoby — in the form of classical structures of silicon
