Controversial question of the existence of extraterrestrial life … require new approaches and especially the acceptance of new premises

Still remains a series of puzzles that encourage human reason, and generates all sorts of existential questions: Is there life in the universe? There are older than the terrestrial civilization? Earth is the only inhabited planet? Summary of all information obtained by observation and / or discovery will lead to research that will contribute to solving them in time, inevitably leading to overall human progress. Exobiologilor studies, search for extraterrestrial life attempts to contact any civilization in the universe, are important for the existence and future of our species as a single entity, existing intelligence Terra waters. Warnings past, present and hope for the future logic converge in a plea for enriching human knowledge about heritage, leading inevitably to unlocking the mysteries of the universe. The phrase: we are not alone in the universe, require new approaches – opinions are seeing in recent times to promote competition in the power of ideas on the existence of extraterrestrial life, based on simplification rather excessive for me. Elogvente statements and studies are published in magazines like British specialists Philosophical Transactions of the Royal Society, the recent research from Cambridge and approved by The Royal Society of London. In the last century many have derided the possibility of extraterrestrial life. In the nineteenth century full of French astronomer, Camille Flammarion, in his book „L’Astronomie Populaire”, the plurality of inhabited worlds. Monitoring of extraterrestrial life begins with 1960, when American astronomer Frank Drake kick off the „OZMA” the name given in memory of the enchanting wizard of Oz countries, pointing at the Green Bank radio telescope, a star similar to our Sun, Tau Ceti. In November 1961 organized the first „Conference on extraterrestrial life, at Green Bank, and featuring his famous equation, or Drake’s formula. At the base has accepted a number of hypotheses for the appearance of life such as: the existence of a planet size, orbit, rotation and revolution movement, temperature, amount of water, relative and similar to those of Earth. This system must belong to a planet-sized stars, like the sun. (Only in the Milky Way is estimated over 8 billion of these stars). Equation to allow estimation of the number N of advanced technological civilizations in the Milky Way. Each term of this equation can not be measured only in a subjective manner and within the only two possible scenarios: one maximal (optimistic) and one minimum (pessimist). Equation depends on the number of stars are born every year in our galaxy, the number of stars with planetary systems like our solar system, the number of planets that hold the necessary conditions for the emergence of life, the number of planets where life actually occurred, the number of planets with intelligent life that has evolved, the probability of intelligent forms have the ability and desire to communicate with others in the galaxy, and the time that a civilization can reach a stage of advanced technology necessary interstellar communication. According to the equation in case of an optimistic scenario there would be 10 billion civilizations, and if a pessimistic conception, the result is 1, so a single civilization – the Earth. Following the conference specialists in the field have accepted an intermediate value N = 50 000 possible only civilizations in the Milky Way. Thus were demarcated a number of programs for the discovery of extraterrestrial life. The most prestigious programs for searching and explaining evidence of extraterrestrial life are: FOG (Russia) – Communication with Extra Terrestrial Intelligence and SETI (USA) Search for Extra Terrestrial Intelligence. In the search for extraterrestrial life a step forward was made at the end of the twentieth century by the emergence of a new science-exobiologia which give implicitly anthropocentric way of thinking, then the only forms of life such as those known to us until now. Preconceived ideas as cutting off the only forms of life would be based only on molecular chains of carbon whose main element we consider in the coming years we will see the extraordinary discoveries in the existence of life in the universe. Maybe a new hypothesis should be accepted by researchers in the field, the existence of life on structuralitatii problem, given a drug that is not material in itself, but the overwhelming role in the emergence of complex structures of life to be a primary substance, not necessarily carbon.

Anyway I am just a simple binary civilization …

Problema controversata a existentei vietii extraterestre …necesita noi abordari si mai ales  acceptarea unor noi premize

Persista inca, o serie de enigme care incita ratiunea umana, si genereaza tot felul de intrebari existentialiste: Exista viata in Univers? Exista civilizatii mai vechi decat cea terestra? Terra este singura planeta locuita? Sumarea tuturor informatiilor obtinute prin observatie si/sau descoperire, vor duce la cercetari care vor contribui la solutionarea lor in timp, ducand inevitabil la progresul omenirii per ansamblu. Studiile exobiologilor, cautarea vietii extraterestre incercarile de a lua legatura cu eventuale civilizatii din Univers, sunt importante pentru existenta si viitorul speciei noastre ca si singura entitate inteligenta existent ape Terra. Avertismentele trecutului, logica prezentului si speranta pentru viitor converg intr-o pledoarie pentru imbogatirea tezaurului cunosterii umane, ducand inevitabil la descifrarea tainelor universului.

Sintagma: nu suntem singuri in univers, necesita noi abordari – opinii

Observam in ultimul timp o competitie in promovarea in forta a ideilor referitoare la existenta vietii extraterestre, pe baza unor simplificari dupa mine destul de excessive. Sunt elogvente declaratiile si studiile specialistilor englezi publicate in reviste gen Philosophical Transactions of the Royal Society, al recentelor cercetari de la Cambridge si agreate de The Royal Society of London. In ultimul secol multi au ironizat posibilitatea existentei vietii extraterestre. In plin secol al XIX-lea astronomul francez, Camille Flammarion, prezenta in cartea sa “L’Astronomie populaire”, pluralitatea lumilor locuite. Monitorizarea vietii extraterestre incepe prin 1960, cand astronomul American Frank Drake da startul proiectului “OZMA” nume dat in amintirea feericei tari a vrajitorului Oz, indreptand radiotelescopul de la Green Bank, spre o stea asemanatoare Soarelui nostru, Tau Ceti. In noiembrie 1961 organizeaza prima “Conferinta asupra vietii extraterestre”, la Green Bank, prezentand si celebra sa ecuatie , sau “formula lui Drake”. La baza au fost acceptate o serie de ipoteze pentru aparitia vietii cum ar fi: existenta unei planete cu dimensiuni, orbita, miscare de rotatie si de revolutie, temperatura, cantitate de apa, relative si asemanatoare cu cele ale Terrei. Aceasta planeta trebuie sa apartina sistemului unei stele de marime medie, similare cu Soarele.(numai in Calea Lacteea sunt estimate peste 8 miliarde de astfel de stele). Ecuatia sa permite estimarea numarului N de civilizatii tehnologice avansate din Calea Lactee. Fiecare termen al acestei ecuatii nu poate fi evaluat decat intr-o maniera subiectiva si in cadrul a doar doua scenarii posibile: unul maximal(optimist) iar altul minimal(pessimist). Ecuatia depinde de numarul de stele care se nasc in fiecare an in galaxia noastra, de numarul stelelor cu sisteme planetare asemanatoare sistemului nostru solar, de numarul planetelor care detin conditiile necesare aparitiei vietii, de numarul planetelor pe care viata a aparut efectiv, de numarul planetelor cu viata care a evoluat spre inteligenta, de probabilitatea ca formele inteligente sa aiba capacitatea si dorinta de a comunica cu altele din galaxie, si de timpul in care o civilizatie poate atinge un stadiu tehnologic avansat necesar comunicarii interstelare. Conform ecuatiei in cazul unui scenariu optimist ar exista 10 miliarde de civilizatii, iar in cazul unei conceptii pesimiste, rezultatul este 1, deci o singura civilizatie – cea terestra. In urma conferintei specialistii in domeniu au acceptat o valoare intermediara N= 50.000 civilizatii posibile numai in Calea Lactee. Astfel au fost demarcate o serie de programe pentru descoperirea vietii extraterestre. Cele mai prestigioase programe pentru cautarea dovezilor si explicarea vietii extraterestre sunt: CETI(Rusia) – Communication with Extra Terrestrial Intelligence, si SETI(SUA) Search for Extra Terrestrial Intelligence. In cautarea vietii extraterestre un pas inainte s-a realizat la sfarsitul secolului XX prin aparitia unei noi stiinte- exobiologia, care renunta implicit la modul de gandire antropocentrist, dupa care singurele forme de viata ar fi cele cunoscute de noi pana acum. Renuntand la ideile preconcepute ca singurele forme de viata ar fi bazate doar pe lanturile moleculare al carei element principal este carbonul putem considera ca vom asista in urmatorii ani la descoperiri extraordinare in domeniul existentei vietii in univers. Poate o noua ipoteza ar trebui acceptata de cercetatorii din domeniu, referitor la problema structuralitatii existentei vietii, adica sa nu primeze substanta materiala in sine ci rolul covarsitor in aparitia vietii sa fie complexitatea structurilor unei substante primordiale, si nu neaparat carbonul.

oricum suntem doar o simpla civilizatie binara…
