The astronomer assumes that there can be a club of civilizations that are hidden from people.
Scottish astronomer Duncan Forgan reported, people are not currently met aliens, because the world can exist “clicks” aliens who conceal their existence from the Earth.
As follows from the article in the electronic library Arxiv.org previously we have created a formula that allows to calculate the number of civilizations in the galaxy, but according to this theory people should be able to meet other civilizations.
Scientist double-checked this theory and suggested that the people still had not met the aliens, for one simple reason — they are hiding from earthlings.
The researcher assumes that the reasons for this may be many, one of the options that the aliens consider humans to be an underdeveloped civilization in order to contact residents.
Forgan suggests that there may be a club of civilizations that are hidden from people.
