Scientists have explained why we will never find aliens
British physicists have found new evidence that we know about the existence of living beings on other planets.
“Colleagues say that we did not find traces of aliens on the grounds that intelligent life arises in the Universe extremely rare. But then it must be extremely rare, disappear very quickly or to conceal himself from the rest. All such explanations have very strange and often unrealistic,” says Anders Sandberg (Anders Sandberg), Oxford University (UK). Article by British researchers to be published in the journal Proceedings of the Royal Society of London A.
More than half a century ago, the American astronomer Frank Drake developed a formula for calculating the number of civilizations in the Galaxy with whom contact is possible, trying to estimate the chances of detection of extraterrestrial intelligence and life.
Physicist Enrico Fermi in response to a high estimate of the chances of interplanetary contact the Drake equation was formulated the thesis, which is now known as the Fermi paradox: if extraterrestrial civilizations so much, then why the mankind does not observe any traces of them?
This paradox, scientists have tried to solve in many ways, the most popular of which is the hypothesis of a “unique Earth”. She suggests that for the emergence of intelligent beings unique requirements, in fact, a full copy of our planet.
