In 1950, the Italian-American physicist Enrico Fermi wondered question: if the universe is teeming with intelligent life, then why aliens still have not contacted us? So-called The Fermi paradox has been discussed for 68 years, and scientists put forward various theories about this.
Some say that intelligent life meets in the infinite Universe (in which alone galaxies, like ours, quadrillion) so rare that we are unlikely to ever see representatives extraterrestrial civilization. According to others, the human race is so far the most developed, and it is we who must seek contact with aliens, not the other way around.
If you believe the third, advanced civilizations (on Earth itself there were several) have the ability to destroy themselves, so they disappear at a certain stage of development without moving far beyond the limits of their star system or a little further. Finally, another the hypothesis is that the “green men” who are much smarter us, prefer not to interfere in the life of earthlings in any way for other reasons – just watching us, and possibly experimenting.
Another hypothesis why aliens shun us
A few days ago, Professor Adrian Kent of Canada Institute of Theoretical Physics at Waterloo voiced a new explanation Fermi paradox. The scientist suggests that the most developed civilizations in the universe are those that possess valuable and scarce resources, whatever they are.
However, over time, these resources begin to deplete, and civilization passes to the economical mode of their use. Then, they say, the inhabitants of a hypothetical distant planet understand that they cannot take risks while traveling in space and opening up in this way to other humanoids in the universe, and “lie at the bottom”, not wanting to somehow interact with others civilizations.

Kent cites the Earth as an example. As you know, our The “blue ball” has many valuable resources: water, air, minerals, plant organics. Scientists don’t stop say that with current rates of consumption ever on the planet will certainly begin to lack all this wealth.
Adrian Kent asks a perfectly logical question: is it ready humanity is risking its resources by seeking others sentient beings in the universe? Are we not afraid that the “green little men “, having received a signal from the Earth, will come here not for friendly handshakes, but they will want to take possession of our resources, which we and so few?
However, a similar theory has undoubtedly been put forward before, just a little bit under another “sauce”: any civilization in the universe, trying to “reach out” to other civilizations, must understand that aliens can be aggressive, and instead of well-wishers cruel invaders will come to us. The deceased spoke about this now Stephen Hawking …
