Russian billionaire Yuri Milner promises to allocate $ 100 million for acquisition time using the best telescopes of the planet and the development of new methods of searching for radio signals of extraterrestrial origin. Why the businessman has decided to spend so much money?
Not all scientists are convinced that SETI (Search for Extraterrestrial Intelligence is the General name of projects to search for extraterrestrial intelligence) is moving in the right direction. Some even believe that the search for radio signals from outer space devoid of meaning. Will Milner to expand bottlenecks SETI?
In 1950 Enrico Fermi formulated a funny paradox: for some reason the aliens, if any, categorically not in a hurry to contact with us. As soon as civilization takes possession of even such primitive technology, as a small thermonuclear bomb, it acquires the ability to colonize the entire Galaxy — for earthlings the time of such settlement a conservative figure would not have exceeded 3.75 million years. If we consider that this colonization is too expensive, you can make cheap robotic probes or just send radio signals to other star systems.
As we now know, the most earth-like planets in the Universe were formed a few billion years before ours. Seemingly this means that over c the Big Bang of a century our system could be repeatedly colonized by extraterrestrial civilizations (EC) — more than a thousand times, if we consider only our galaxy, and over a million times, if you take into account inhalations civilization. But any traces of the colonizers, we do not see, as well as their space probes. A century of observational SETI evidence that the excess foreign radio signals around us unnoticed.
Dozens of solutions to the paradox can be summarized in three main points of view. First, waving Occam’s razor, says: if we don’t see the CC, they don’t exist.
