Scientists have refuted the assumption of Stephen Hawking.
Specialist from the Institute of search for extraterrestrial intelligence (SETI) has denied speculation of Stephen Hawking that aliens could attack the Earth.
According to the expert, there are a number of reasons why such a development impossible.
One of the leading members of the organization Seth Shostak said that the public fears in vain the attack of the aliens. For quite a long time humanity is in space leaves various traces of their existence, among which artificial satellites, probes, radio signals, etc. If the aliens were aggressive, they have long been attacked on the Ground, noticing that there lives a underdeveloped civilization.
In addition, the expert is sure that in the vicinity of the Solar system there is not a single organism that possesses technologies for war in space. If such creatures really lived somewhere nearby, people would be able to detect their traces. Those who live far too long to get to the Ground. It will change dozens or even hundreds of generations.
It should be noted that attackers have to have really unique weapons designed for combat in zero gravity.
